Fricção Cirúrgica: Desafios e Realidades no Centro Cirúrgico

Fricção Cirúrgica: Desafios e Realidades no Centro Cirúrgico

No universo da teoria militar, Carl von Clausewitz introduziu o conceito de “fricção” para descrever as dificuldades e imprevistos que complicam a execução dos planos de guerra. Esse conceito, no entanto, transcende o campo de batalha e encontra paralelos surpreendentes em outros cenários complexos e de alta pressão, como o centro cirúrgico. A “fricção cirúrgica” refere-se às diversas dificuldades que cirurgiões e equipes médicas enfrentam durante procedimentos, afetando a eficiência e os resultados esperados.

Imprevisibilidade e Complexidade

Assim como na guerra, a cirurgia está repleta de elementos imprevisíveis. Mesmo com um planejamento meticuloso e uma equipe altamente treinada, fatores inesperados podem surgir. Complicações anatômicas, reações adversas a medicamentos e condições pré-existentes do paciente são apenas alguns exemplos de imprevistos que podem alterar drasticamente o curso de uma operação.

“Tudo na guerra é simples, mas a coisa mais simples é difícil.” – Carl von Clausewitz

Equipamentos e Tecnologia

Embora a tecnologia moderna tenha revolucionado a medicina, ela também introduz sua própria forma de fricção. Equipamentos sofisticados podem falhar ou não funcionar conforme esperado. A calibração inadequada de máquinas, falhas de software em dispositivos médicos e até problemas de energia podem criar obstáculos significativos durante uma cirurgia. Manter e operar esses equipamentos requer um nível elevado de expertise técnica e atenção constante.

“A fricção é o único conceito que distingue amplamente a guerra real da guerra no papel.” – Carl von Clausewitz

Comunicação e Coordenação

A comunicação é crucial em um centro cirúrgico, onde cada membro da equipe desempenha um papel vital. Qualquer falha na transmissão de informações pode ter consequências sérias. Mal-entendidos entre cirurgiões, anestesistas, enfermeiros e técnicos podem levar a erros críticos. A coordenação eficaz é essencial para garantir que todos os procedimentos sejam executados sem problemas, desde a preparação do paciente até a conclusão da cirurgia.

“A mais triviais coisas, vistas no contexto de uma operação militar, parecem ir contra você.” – Carl von Clausewitz

Fatores Humanos

A fricção também emerge das variáveis humanas. Fadiga, estresse e pressão emocional podem afetar o desempenho dos profissionais de saúde. Cirurgiões e enfermeiros frequentemente trabalham em turnos longos e intensos, o que pode levar a lapsos de concentração e julgamento. A capacidade de um profissional de saúde de manter a calma e tomar decisões rápidas e precisas é testada continuamente no ambiente cirúrgico.

“A guerra é o domínio da incerteza; três quartos dos fatores sobre os quais a ação é baseada estão enfiados na névoa de maior ou menor incerteza.” – Carl von Clausewitz

Logística e Suprimentos

A logística desempenha um papel crítico no funcionamento suave de um centro cirúrgico. A disponibilidade de instrumentos estéreis, medicamentos e outros suprimentos médicos é fundamental. Qualquer atraso na entrega de suprimentos ou problemas com a esterilização de instrumentos pode interromper um procedimento e aumentar os riscos para o paciente.

“A guerra é a área da atividade humana mais suscetível à fricção.” – Carl von Clausewitz

Mitigando a Fricção Cirúrgica

Assim como os comandantes militares desenvolvem estratégias para mitigar a fricção na guerra, as equipes cirúrgicas adotam várias práticas para reduzir as dificuldades inesperadas. Treinamento rigoroso e contínuo, simulações de procedimentos complexos e protocolos claros de comunicação são essenciais. Além disso, a manutenção regular de equipamentos e a implementação de sistemas de redundância podem ajudar a minimizar falhas técnicas.

“A habilidade de um líder militar reside na manutenção de uma visão clara e objetiva apesar da fricção.” – Carl von Clausewitz

A fricção cirúrgica, como descrita por Clausewitz em um contexto militar, reflete a realidade desafiadora do centro cirúrgico. Reconhecer e preparar-se para essas dificuldades é crucial para garantir a segurança do paciente e o sucesso das operações. Em última análise, a habilidade das equipes médicas em gerenciar a fricção cirúrgica determina a eficácia e a eficiência das intervenções cirúrgicas.

Charlie Munger’s 25 Cognitive Biases Applied to Digestive Surgery

In the demanding field of digestive surgery, excellence is not just a goal but a necessity. By integrating the profound insights of Charlie Munger on cognitive biases with the motivational principles of Zig Ziglar, surgeons can achieve superior performance and enhance patient care. This comprehensive guide offers actionable recommendations and illustrative examples tailored to the unique challenges of digestive surgery, ensuring that every decision is informed, balanced, and patient-centered.

  24. Lollapalooza Tendency
    • Example: Multiple biases leading to a major error in patient care.
    • Recommendation: Be vigilant about recognizing and mitigating multiple biases simultaneously.
  25. Tendency to Overweight Recent Information
    • Example: Giving undue importance to the most recent piece of information received.
    • Recommendation: Balance recent information with a thorough review of all relevant data.

Just as Charlie Munger highlights the importance of avoiding cognitive biases for effective decision-making, Zig Ziglar teaches us the significance of attitude and continuous improvement. For a digestive surgeon, applying these principles can transform clinical practice, leading to exceptional performance and superior patient care. Zig Ziglar said, “You don’t have to be great to start, but you have to start to be great.” Every step taken towards overcoming cognitive biases and adopting evidence-based practices is a step towards excellence. By recognizing and mitigating these 25 cognitive biases, you position yourself for an assistive performance that not only treats but truly cares for patients.

Recommendations from Zig Ziglar for Digestive Surgeons

  1. Believe in Yourself: “If you can dream it, you can achieve it.” Trust in your ability to learn and grow continually.
  2. Set Clear Goals: “A goal properly set is halfway reached.” Define clear objectives to enhance your skills and knowledge.
  3. Maintain a Positive Attitude: “Your attitude, not your aptitude, will determine your altitude.” Face challenges with a positive and resilient mindset.
  4. Learn from Every Experience: “Failure is an event, not a person.” Use every situation, good or bad, as a learning opportunity.
  5. Serve Others with Excellence: “You can have everything in life you want if you will just help enough other people get what they want.” Focus on patient well-being in all decisions.

By integrating Munger’s lessons and Ziglar’s motivational wisdom, you will not only become a better surgeon but also an inspiring leader and a true advocate for excellence in medicine. Remember always: “Success is doing the best we can with what we have.” Keep evolving, seeking knowledge, and above all, serving your patients with dedication and compassion. Together, let’s transform the practice of digestive surgery, one step at a time, towards the excellence our patients deserve.

Mondino de Luzzi (1270-1326) e o surgimento do MONITOR DE ANATOMIA

Mondino, oriundo de Bolonha, nasceu e concluiu seus estudos em sua cidade natal, obtendo sua graduação por volta do ano de 1290. A partir de 1306, tornou-se membro do corpo docente da universidade local. Ele recebeu instrução de Tadeu, compartilhando a mesma época de estudo com Mondeville, e dedicou-se de maneira sistemática à Anatomia, realizando dissecações públicas do corpo humano. Mondino é reconhecido como o pioneiro na “restauração” da Anatomia. Em 1316, publicou o tratado intitulado “Anothomia”, considerado o primeiro trabalho “moderno” na área, distinguindo-se por sua abordagem prática e original, diferenciando-se de simples traduções de textos clássicos.

A obra de Mondino apresenta desafios, conforme apontado por Singer (1996), destacando-se a nomenclatura confusa e as condições peculiares da dissecação naquela época. A ausência de conservantes apropriados, apesar do conhecimento acumulado pelos egípcios em técnicas de embalsamamento, tornava a dissecação um processo extenuante, preferencialmente realizado no inverno e em até quatro dias específicos para cada região do corpo.

Apesar de imprecisões anatômicas, como apontado por Friedman e Friedman (2001), Mondino desempenhou um papel crucial na instituição da dissecação como componente essencial do estudo anatômico. Essa prática foi posteriormente integrada ao currículo médico da Universidade de Bolonha, permitindo, até o final do século XVI, que as execuções de criminosos fossem realizadas de maneira que não comprometesse o trabalho anatômico, representando um avanço no uso do corpo humano na construção do conhecimento.

A contribuição de Mondino foi duradoura, pois sua obra foi uma das principais fontes de conhecimento em Anatomia humana por mais de duzentos anos, até o advento da obra de Vesalius no século XVI. Ao assumir a cátedra da disciplina, Mondino introduziu uma nova dinâmica nas aulas de Anatomia, afastando-se da dissecação e inserindo o ostensor (aluno) e o demonstrator ou incisore (técnico) para conduzirem os procedimentos, enquanto os alunos observavam.

As técnicas predominantes, como dissecação a fresco, maceração e preparações secas ao sol, eram utilizadas por Mondino e seus contemporâneos. Apesar de suas reservas quanto à maceração, essa técnica continuou a ser praticada, como confirmado pelos textos de Guido de Vigevano em 1345, representando a persistência do uso da dissecação para fins educacionais em Bolonha.

Mondino não expandiu significativamente o conhecimento anatômico existente, mas contribuiu para a formação de anatomistas que perpetuaram a tradição da disciplina em Bolonha, Pádua e em outros países. Notáveis estudiosos, como Gabrielle de Gerbi e Alessandro Achillini, aprimoraram e ampliaram as descrições anatômicas de Mondino em suas próprias contribuições.

A anatomia permanece como alicerce fundamental para o desenvolvimento da medicina ao oferecer conhecimentos cruciais para o adequada exercício profissional. O legado de anatomistas como Mondino, que enfrentaram desafios significativos em suas dissecações pioneiras, ecoa nas salas de aula modernas. A persistência do estudo anatômico é essencial para a formação médica, e os monitores de anatomia desempenham um papel vital nesse processo educativo. Atuando como elo entre a teoria e a prática, esses monitores, herdeiros contemporâneos do ostensor de Mondino, desempenham um papel crucial ao auxiliar na orientação dos alunos nas complexidades da dissecação e na compreensão da anatomia humana. Sua contribuição atual é inseparável do legado histórico, garantindo que o conhecimento anatômico continue a florescer, moldando as futuras gerações de profissionais de saúde e consolidando a anatomia como um pilar indispensável no edifício da medicina.

ODE AOS MESTRES ANATÔMICOS

Ser mestre é perpetuar juventude, Afrontando o inexorável fio do tempo, Desdobrando-se, multiplicando-se, Nas almas dos discípulos, criando ensejo.

Escolas germinam quando a maturidade, Se entrelaça à força do nobre sentimento, O mestre, sábio, fala à mente e coração, Exemplo luminoso, toque profundo, alento.

Na odisseia do saber, mestre é guia, Navegando oceanos de experiência viva, Com luz, desbrava trilhas no pensamento.

O mestre, como sol em seu zênite, Aquece a jornada do aprendizado, Conservando-se jovem, eternamente, erudito.

Assim, na sala de aula, é o comandante, Que com alma e sabedoria encanta, O mestre, semeando luz e meta.

Small desires have a life as short as the journey of those who pursue them.

The will is the road: those who want, move forward; those who don’t, justify.

Those who want find the way; those who don’t, know the reasons.

Those who want make sacrifice meaningful.

Those who don’t want declare the barriers that ease guilt.

Those who don’t want turn restriction into prohibition, limit into decision.

Those who want decide for the outcome to be achieved.

Those who don’t want decide based on the difficulty encountered.

What is challenging for one is motivating for another.

What is sacrifice for one is commitment for the other.

The challenge, for both, changes – irritating or exciting, obstacle or opportunity. Those who want accept and persist.

Those who don’t want retreat and give up.

The drive of man is his GREAT desire.

Small desires have a life as short as the journey of those who pursue them.

O Estoicismo Cirúrgico

Aplicando Princípios Filosóficos na Prática Cirúrgica

O campo da cirurgia, especialmente no tratamento das doenças do aparelho digestivo, exige não apenas habilidades técnicas refinadas, mas também resiliência emocional e ética sólida. A prática cirúrgica, por sua natureza, envolve decisões difíceis, momentos de pressão extrema e desafios inesperados. Nesse contexto, os princípios do estoicismo, filosofia praticada por pensadores como Sêneca, Epicteto e o imperador Marco Aurélio, oferecem ferramentas valiosas para que o cirurgião enfrente a complexidade emocional e ética de sua profissão.

Prof. Dr. Ozimo Gama
Et Fortior

Neste artigo, direcionado a estudantes de medicina, residentes de cirurgia geral e pós-graduandos em cirurgia do aparelho digestivo, vamos explorar como os princípios estoicos podem ser aplicados à prática cirúrgica, promovendo não apenas a eficiência técnica, mas também a excelência ética. Abordaremos as virtudes estoicas que podem moldar o comportamento de um cirurgião, aprimorando sua capacidade de lidar com adversidades e tomar decisões sábias no centro cirúrgico.

1. Aceitação das Limitações: “Primum non nocere” em Ação

O princípio estoico de aceitar o que não pode ser mudado é fundamental para o cirurgião. Em um procedimento cirúrgico, o inesperado pode surgir a qualquer momento. O estoicismo ensina que devemos focar no que está sob nosso controle – nossas ações e reações – e aceitar com serenidade aquilo que foge ao nosso alcance, como complicações imprevistas ou resultados adversos. Essa atitude fortalece o cirurgião, permitindo-lhe manter a calma e a clareza mental em situações críticas.

“O que está no meu poder é como reajo ao que acontece. O resto está fora do meu controle.” – Marco Aurélio

2. A Virtude da Perseverança em Meio às Adversidades

A cirurgia, especialmente nas doenças do aparelho digestivo, frequentemente envolve longos procedimentos, altos níveis de complexidade e a necessidade de ajustes rápidos. O estoicismo valoriza a perseverança diante de dificuldades, uma virtude essencial para o cirurgião que deve persistir no cuidado dos pacientes, mesmo em cenários complicados. A capacidade de continuar com foco e determinação, mesmo em circunstâncias adversas, é o que distingue o cirurgião estoico.

“A adversidade é uma oportunidade para a virtude.” – Marco Aurélio

3. Disciplina e Autocontrole no Centro Cirúrgico

O autocontrole é uma das virtudes centrais do estoicismo, e no campo cirúrgico, é vital que o cirurgião mantenha o controle emocional durante procedimentos complexos. O estoicismo nos ensina a não sermos controlados por emoções passageiras, como medo ou frustração, mas sim a agir com racionalidade. No centro cirúrgico, isso se traduz em decisões conscientes e calculadas, que priorizam o bem-estar do paciente, mantendo a objetividade diante de situações estressantes.

“Não é o que acontece, mas como você reage que importa.” – Marco Aurélio

4. Justiça e a Importância de Tratar Todos os Pacientes com Equidade

Para o cirurgião, a justiça, outro pilar estoico, é essencial. Todo paciente, independentemente de sua condição socioeconômica, deve receber o mesmo nível de cuidado e atenção. A prática cirúrgica ética requer que o cirurgião trate cada paciente com equidade, aplicando os princípios da medicina de maneira justa, sem preconceitos ou favoritismos. O cirurgião estoico vê em cada paciente uma oportunidade de exercer a sua profissão com justiça e integridade.

“A justiça consiste em fazer o que é correto, não o que é popular.” – Marco Aurélio

5. Coragem e Resiliência na Tomada de Decisões Difíceis

A cirurgia muitas vezes exige coragem para tomar decisões difíceis, especialmente em situações de risco à vida do paciente. A filosofia estoica valoriza a coragem como uma virtude indispensável. Para o cirurgião, isso significa enfrentar com firmeza e clareza os dilemas éticos e clínicos, mesmo quando há incertezas. A coragem estoica permite que o cirurgião aja com confiança e serenidade, tomando decisões informadas e moralmente corretas, mesmo em momentos críticos.

“A coragem é a dignidade sob pressão.” – Marco Aurélio

Conclusão

A prática cirúrgica é muito mais do que um conjunto de habilidades técnicas; é uma arte que exige um equilíbrio entre conhecimento, ética e resiliência emocional. Ao adotar os princípios estoicos, o cirurgião pode enfrentar os desafios diários com serenidade, perseverança e justiça, sempre em busca do bem maior para seus pacientes. O estoicismo oferece uma base filosófica robusta para lidar com as pressões da vida cirúrgica, fortalecendo o profissional em sua jornada por excelência técnica e moral.

“A felicidade de sua vida depende da qualidade de seus pensamentos.” – Marco Aurélio

  1. “What we control is what we calmly accept.” – In moments of uncertainty and pressure in the operating room, the serene acceptance of circumstances is crucial for maintaining composure and focus.
  2. “Do not expect the doctors to do everything for you.” – Marcus Aurelius reminds us of the importance of recognizing our own limitations. Collaboration between doctor and patient is essential for effective treatment.
  3. “Pain is inevitable. Suffering is optional.” – When dealing with patients in painful situations, it’s vital to remember that our role extends beyond physical treatment to emotional support and alleviating suffering.
  4. “Doing what needs to be done when it needs to be done, to the best of our ability, is already enough.” – In a profession as demanding as medicine, it’s vital to remember that every effort dedicated to patient care is valuable and meaningful.
  5. “What is morally right is more important than what is legally right.” – In some situations, it may be necessary to make decisions that go beyond protocol, aiming for the best interest of the patient.
  6. “To wait is harmful. Not to wait is necessary.” – Readiness and agility in making medical decisions can be crucial in emergency situations.
  7. “Time is a river, and facts are currents; we cannot escape, we cannot choose where we will go, nor when, nor how.” – This reflection reminds us of life’s impermanence and the importance of cherishing every moment in medical practice.
  8. “Man’s health is our treasure.” – Marcus Aurelius emphasizes the valuable responsibility doctors have in preserving and restoring individuals’ health.
  9. “Every day that dawns brings some evil, which we must accept, for no day will be without it.” – Recognizing that challenges are part of the medical journey allows professionals to face them with courage and determination.
  10. “Where is the good, if not in doing good to those in need?” – The practice of medicine is a living testament to compassion and altruism. Through it, doctors have the opportunity to demonstrate the true essence of human kindness.

Conclusion

Just as Marcus Aurelius faced the challenges of the Roman Empire with serenity and wisdom, the modern surgeon finds in his words a guide to practicing medicine with virtue and humanity. By uniting technical skill with Stoic philosophy, the surgeon becomes not only a master of their craft but also an example of Stoic activity for the entire medical community. May each operating room be a temple of virtue and care, where the legacy of Marcus Aurelius lives on through the hands of Stoic surgeons.

The Art of Healing: Wisdom from Opus Dei for Medical Professionals

1. “Work is a path to holiness.” – Just as in Opus Dei, where work is considered a means to grow closer to God, in the field of medicine, every interaction with a patient, every diagnosis, and every surgery is an opportunity to serve and make a positive impact.

2. “In your daily work, offer up small sacrifices for your patients.” – Much like Opus Dei encourages offering up small sacrifices for spiritual growth, in medicine, dedicating extra time, attention, or effort for a patient’s well-being can be a powerful form of compassion.

3. “Strive for excellence in your field; it is a reflection of your dedication to your patients.” – Opus Dei emphasizes the pursuit of excellence in one’s profession as a form of service to God. Similarly, in medicine, continuous learning and improvement directly benefit the quality of care provided to patients.

4. “Treat each patient with dignity, respect, and kindness.” – This fundamental principle aligns with Opus Dei’s emphasis on valuing every individual. In medicine, showing compassion and empathy is as important as clinical expertise.

5. “Pray for guidance in making difficult decisions.” – Just as Opus Dei encourages seeking spiritual guidance in challenging situations, in medicine, turning to one’s faith for moral and ethical dilemmas can provide clarity and a sense of purpose.

6. “Foster a culture of trust and collaboration among colleagues.” – Opus Dei emphasizes unity and mutual support among its members. Similarly, in the medical field, teamwork and open communication are vital for providing the best possible care for patients.

7. “Never underestimate the power of a kind word or gesture.” – Small acts of kindness, like those encouraged in Opus Dei, can have a profound impact on a patient’s experience and recovery in the medical setting.

8. “Cultivate a spirit of gratitude for the opportunity to serve others.” – Recognizing the privilege of being able to heal and alleviate suffering is a perspective shared by Opus Dei and medical professionals alike.

9. “Strive for balance between professional and personal life.” – Opus Dei emphasizes the importance of a balanced life. In medicine, maintaining a healthy work-life balance is crucial for sustaining a long and fulfilling career.

10. “Embrace the challenges of medicine as opportunities for growth and service.” – Opus Dei encourages embracing life’s challenges as a means of spiritual growth. Likewise, in medicine, facing the complexities and difficulties of healthcare with dedication and compassion can lead to profound personal and professional development.

Incorporating these principles from Opus Dei into the practice of medicine can not only enhance the quality of care provided but also contribute to a more compassionate and fulfilling healthcare experience for both practitioners and patients alike.

Liderança Inspiradora de Lord Nelson: Lições para Cirurgiões Contemporâneos

A história nos presenteou com inúmeros líderes notáveis, cujas habilidades e características têm inspirado gerações ao longo dos séculos. Um desses ícones é Lord Nelson, o lendário almirante britânico do século XVIII, conhecido por sua coragem e maestria tática nas batalhas navais. Surpreendentemente, as características de liderança de Lord Nelson têm aplicações valiosas mesmo na prática contemporânea da cirurgia. Neste artigo, exploraremos algumas dessas qualidades e como nós cirurgiões podemos aplicá-las para alcançar o sucesso em nossas batalhas cirúrgicas.

“Eu sou inabalável em minha determinação, como nunca estive em minha vida, desde que coloquei o pé no convés de um navio.”

1. Determinação Inabalável: Lord Nelson era conhecido por sua determinação inabalável em alcançar seus objetivos. Ele enfrentou inúmeras adversidades e desafios durante suas batalhas navais, mas nunca desistiu diante das dificuldades. Os cirurgiões contemporâneos podemos aprender com essa qualidade, mantendo-se resilientes diante de obstáculos, buscando soluções mesmo nas situações mais desafiadoras e garantindo o melhor atendimento possível para nossos pacientes. Durante a Batalha do Nilo, em 1798, Nelson enfrentou condições adversas quando a frota britânica ficou encalhada em bancos de areia. Enfrentando uma situação aparentemente desesperadora, ele permaneceu determinado a superar os obstáculos para alcançar a vitória. Com habilidades táticas brilhantes, Nelson conseguiu finalmente manobrar sua frota para fora dos bancos de areia e alcançar uma vitória decisiva sobre a frota francesa.

“Eu sempre fui um covarde em tudo, exceto nesta profissão.”

2. Coragem sob Pressão: Durante a Batalha de Copenhague, em 1801, Nelson foi ordenado a se retirar pelo comandante em chefe, mas ele ignorou a ordem e ergueu o telescópio em seu olho cego para afirmar que não conseguia ver o sinal. Ele então liderou seu esquadrão em um ataque corajoso, superando uma poderosa defesa dinamarquesa. Sua determinação e coragem sob pressão foram fundamentais para a vitória britânica. Em meio ao caos e perigo das batalhas navais, Lord Nelson demonstrou coragem excepcional. Seu exemplo inspirador pode nos lembrar da importância de permanecermos calmos e focados, mesmo durante procedimentos complexos ou emergências médicas. A coragem para tomar decisões rápidas e precisas pode fazer a diferença entre a vida e a morte em uma sala de cirurgia.

“A vontade não pode ser chamada de coragem, mas dever, o resultado da força da mente; e qualquer um que possua esse poder, quando chega a hora de agir, encontrará a coragem que necessita.”

3. Liderança Carismática: Lord Nelson conquistou o respeito e a admiração de sua tripulação com sua liderança carismática. Durante a Batalha do Nilo, quando o perigo era iminente e a tripulação estava nervosa, Nelson subiu ao convés e enfrentou corajosamente o inimigo, encorajando seus marinheiros a seguirem seu exemplo. Sua presença inspiradora foi fundamental para manter o moral elevado e motivar sua equipe a lutar com determinação. Lord Nelson era conhecido por sua liderança carismática e inspiradora. Ele conquistou o respeito e a lealdade de sua tripulação com sua empatia e capacidade de se conectar emocionalmente com seus marinheiros. Os cirurgiões contemporâneos também podem se beneficiar ao desenvolver uma liderança que inspire confiança e motivação em suas equipes médicas, promovendo um ambiente colaborativo e eficiente.

“Eu planejo que cada homem atue de acordo com o que vê melhor, mas qualquer homem que venha entre as duas frotas, não pode ser errado, portanto, não pode ser chamado de insubordinação, mas uma obediência em que cada oficial julga por si mesmo o que é melhor a ser feito.”

4. Capacidade de Adaptação: Durante a Batalha de Trafalgar, a estratégia inicial de Nelson era enfrentar a frota inimiga de maneira mais tradicional. No entanto, quando percebeu que a formação inimiga era mais forte do que o esperado, ele rapidamente adaptou sua tática e implementou a “manobra de Nelson”, cortando a linha inimiga e concentrando seu poder de fogo para alcançar a vitória. Durante suas batalhas, Lord Nelson enfrentou situações imprevistas e mudanças de planos. Sua capacidade de adaptação e flexibilidade permitiu-lhe ajustar suas estratégias conforme necessário. Na cirurgia contemporânea, os profissionais também devem ser ágeis e adaptáveis, prontos para responder a mudanças repentinas durante procedimentos cirúrgicos complexos ou emergências médicas.

“Seja qual for a estação em que você estiver, carregue consigo o pensamento de que todos os olhos estão voltados para você. Comande a si mesmo sempre que for o exemplo de todos os outros.”

5. Comunicação Efetiva: Lord Nelson era conhecido por sua habilidade de comunicação clara e direta com sua equipe. Antes da Batalha do Nilo, ele escreveu uma carta aos marinheiros enfatizando a importância da vitória e oferecendo palavras de encorajamento. Sua mensagem sincera e motivadora demonstrava sua preocupação com o bem-estar de sua tripulação e ajudou a criar um senso de propósito comum entre seus homens. A comunicação efetiva era uma das principais características de liderança de Lord Nelson. Ele sabia como transmitir suas ordens com clareza e também valorizava o feedback de sua equipe. Cirurgiões contemporâneos podem seguir esse exemplo, enfatizando a comunicação transparente com seus colegas e pacientes para garantir que todos estejam alinhados quanto aos procedimentos e tratamentos.

Em suma, a história de Lord Nelson nos ensina que as características de liderança transcendem as épocas e têm aplicação valiosa em diversas áreas, incluindo a medicina. Ao incorporar a determinação, coragem, carisma, adaptação e comunicação efetiva de Lord Nelson, podemos nos inspirar e tornar líderes excepcionais em nossas práticas médicas, promovendo um atendimento de qualidade e impactando positivamente a vida dos pacientes. A frase ‘A Inglaterra espera que cada um faça sua parte’ tornou-se um lema inspirador e atemporal, capturando a essência da liderança de Lord Nelson na Batalha de Trafalgar. Essas palavras ecoam através dos séculos, lembrando-nos da importância da responsabilidade individual e do trabalho em equipe para alcançar o sucesso em qualquer empreendimento. Assim como os marinheiros da frota britânica foram impulsionados por esse chamado à ação, também podemos aplicar essa mensagem em nossas próprias vidas e carreiras. Como cirurgiões, somos lembrados da nossa obrigação de desempenhar cada procedimento com diligência e dedicação, e ao mesmo tempo, liderar nossas equipes com empatia e coragem. A mensagem de Lord Nelson nos inspira a superar desafios, enfrentar pressões e trabalhar juntos para alcançar os melhores resultados possíveis em nossas práticas médicas. Ao seguir esse exemplo atemporal de liderança podemos oferecer o melhor atendimento possível aos nossos pacientes e à sociedade.

Ortodoxia Cirúrgica

Embora “Ortodoxia” seja uma obra filosófica e teológica escrita por G.K. Chesterton, suas ideias podem ter algumas aplicações interessantes e reflexivas no cotidiano da cirurgia. Claro que a relação direta pode não ser evidente, mas certos princípios filosóficos podem fornecer perspectivas valiosas para os cirurgiões. Aqui estão algumas maneiras pelas quais as ideias de “Ortodoxia” podem ser aplicadas no contexto cirúrgico:

  1. Valorizar o pensamento paradoxal: A cirurgia é uma disciplina complexa e muitas vezes ambígua, onde os médicos devem tomar decisões cruciais em situações desafiadoras. Valorizar o pensamento paradoxal pode ajudar os cirurgiões a considerar opções diversas e até opostas antes de tomar decisões importantes.
  2. Reconhecimento da complexidade humana: Chesterton destaca a importância de compreender a natureza complexa da realidade. No contexto cirúrgico, isso se traduz em tratar cada paciente como um indivíduo único, com suas próprias circunstâncias médicas, emocionais e sociais. Isso pode ajudar os cirurgiões a abordar cada caso com uma mente aberta e livre de preconceitos.
  3. Equilíbrio entre tradição e inovação: Assim como Chesterton valoriza a tradição cultural, os cirurgiões podem se beneficiar de uma abordagem equilibrada entre as técnicas tradicionais e as inovações médicas. Combinar o conhecimento estabelecido com as mais recentes pesquisas e tecnologias pode levar a melhores resultados para os pacientes.
  4. Enfrentar a incerteza: A cirurgia pode ser imprevisível, e os resultados nem sempre são garantidos. A ortodoxia de Chesterton nos encoraja a aceitar a incerteza e a enfrentar os desafios com coragem e confiança. Essa mentalidade pode nos ajudar a enfrentar situações complicadas e se adaptar a cenários imprevistos.
  5. Importância da ética e moralidade: Chesterton enfatiza a importância da moralidade e da virtude. Na cirurgia, esses princípios são essenciais para garantir a melhor qualidade de atendimento ao paciente, respeitando sempre a dignidade e os direitos humanos.
  6. Valorizar a imaginação: A imaginação é uma parte essencial do trabalho cirúrgico, permitindo aos médicos visualizar procedimentos, simular situações e pensar em soluções criativas. A capacidade de imaginar possibilidades pode ajudar os cirurgiões a planejar cuidadosamente cada intervenção.

Embora “Ortodoxia” não tenha sido escrito com o objetivo específico de se aplicar à cirurgia, as ideias e princípios contidos na obra podem inspirar uma reflexão mais profunda e nos guiar de forma mais consciente, sensível e equilibrada.

As virtudes cardinais cirúrgicas

A prática cirúrgica é uma forma de arte que exige habilidade técnica e precisão, mas vai além disso. Os cirurgiões não apenas dominam as técnicas e procedimentos, mas também são desafiados a aplicar virtudes cardinais em cada etapa do ato operatório. A diérese, exérese, hemostasia e síntese, as quatro fases cruciais da cirurgia, podem ser vistas como um reflexo das virtudes cardinais: prudência, justiça, fortaleza e temperança. Vamos explorar como essas virtudes se manifestam na rotina de um cirurgião comprometido com o bem-estar dos pacientes.

Diérese (A Prudência como Guia) : A primeira etapa da cirurgia, a diérese, é o momento em que o cirurgião realiza uma incisão precisa para acessar o local a ser tratado. A prudência, virtude da sabedoria prática, entra em cena através do domínio da anatomia. O cirurgião deve avaliar cuidadosamente cada caso, analisar os riscos e tomar decisões fundamentadas. A prudência orienta a escolha das melhores abordagens cirúrgicas, levando em consideração a saúde geral do paciente, suas necessidades individuais e o objetivo final da intervenção.

Exérese (A Justiça na Busca pelo Equilíbrio): Na fase de exérese, o cirurgião remove tecidos ou estruturas comprometidas pela doença. Aqui, a justiça desempenha um papel essencial. O cirurgião deve agir com equidade, buscando remover apenas o que é necessário, sem excessos ou negligências. A justiça implica em tratar cada paciente com equidade, respeito e imparcialidade, levando em consideração os melhores interesses do indivíduo e buscando o bem comum. É um compromisso em garantir que o procedimento cirúrgico seja realizado com integridade e sempre em benefício do paciente.

Hemostasia (A Fortaleza para Enfrentar Desafios) : Durante a fase de hemostasia, o cirurgião aplica técnicas para controlar o sangramento e garantir um campo cirúrgico claro. Nesse momento, a fortaleza se faz presente. A cirurgia pode apresentar situações imprevistas, complicações ou momentos de grande pressão. A fortaleza permite ao cirurgião manter-se firme, agir com coragem diante de adversidades e tomar decisões rápidas, mas sábias, para proteger a vida e o bem-estar do paciente. A fortaleza é a virtude que impulsiona o cirurgião a enfrentar desafios com firmeza e superar obstáculos através de uma alma inabalável, mantendo durante todo o procedimento uma determinação com o melhor prognóstico do paciente.

Síntese (A Temperança na Busca do Equilíbrio Final) : A última etapa, a síntese, envolve a restauração da integridade do tecido por meio de suturas ou outros meios. Nesse momento, a temperança se revela. A temperança é a virtude que permite ao cirurgião exercer controle e moderação, evitando excessos e buscando a harmonia. A escolha adequada do material de sutura, a técnica precisa e o cuidado meticuloso são fundamentais. A temperança assegura que a finalização do ato operatório seja feita com prudência, justiça e fortaleza, considerando o bem-estar a longo prazo do paciente.

Logo, podemos concluir que a prática da cirurgia transcende a habilidade técnica e exige o cultivo das virtudes cardinais. A prudência, a justiça, a fortaleza e a temperança tornam-se guias éticos para o cirurgião comprometido com o cuidado ao paciente. A diérese, exérese, hemostasia e síntese, cada uma refletindo uma virtude cardinal, são etapas cruciais em busca da excelência médica. Quando o cirurgião incorpora essas virtudes em sua rotina, ele se torna não apenas um técnico habilidoso, mas um verdadeiro médico que busca o bem-estar e a cura integral do paciente. A arte da cirurgia, assim, se revela não apenas como uma expressão de destreza manual, mas como uma expressão do cuidado compassivo e virtuoso que o médico oferece ao paciente.

Sobre o FUTURO

Aos cinco anos, o que você queria ser quando crescesse?

Médico.

Tudo começou quando eu tinha por volta de 4 – 5 anos e após um acidente domiciliar, precisei passar por uma cirurgia na mão. A forma como aquele profissional que nos atendeu acalmou a angústia dos meus pais e tratou com habilidade o ferimento me marcou profundamente. Apesar de não ter ideia do que isso significaria na minha jornada futura, aquele sentimento de ação e resolução se tornou uma paixão que me acompanha até hoje.

Specific Competence of Surgical Leadership

Surgeons are uniquely prepared to assume leadership roles because of their position in the operating room (OR). Whether they aspire to the title or not, each and every surgeon is a leader, at least within their surgical team. Their clinical responsibilities offer a rich variety of interpretations that prepare them for a broader role in health care leadership. They deal directly with patients and their families, both in and out of the hospital setting, seeing a perspective that traditional health care administrative leaders rarely experience. They work alongside other direct providers of health care, in varied settings, at night, on weekends, as well as during the typical workday. They understand supply-chain management as something more than lines on a spreadsheet.

The Challenges for a Surgical Leader

Surgeons prefer to lead, not to be led. Surgical training has traditionally emphasized independence, self-reliance, and a well-defined hierarchy as is required in the OR. However, this approach does not work well outside the OR doors. With colleagues, nurses, staff, and patients, they must develop a collaborative approach. Surgeons are entrusted with the responsibility of being the ultimate decision maker in the OR. While great qualities in a surgeon in the OR, it hinders their interactions with others. They have near-absolute authority in the OR, but struggle when switching to a persuasive style while in committees and participating in administrative activities. Most surgeons do not realize they are intimidating to their patients and staff. With patients, a surgeon needs to be empathetic and a good listener. A surgeon needs to slow the pace of the discussion so that the patient can understand and accept the information they are receiving. As perfectionists, surgeons demand a high level of performance of themselves. This sets them up for exhaustion and burnout, becoming actively disengaged, going through the motions, but empty on the inside. Given the many challenges surgeons face, it is difficult for them to understand the leadership role, given its complex demands.

Specific Competencies

Authority

Although teams and all team members provide health care should be allowed input, the team leader makes decisions. The leader must accept the responsibility of making decisions in the presence of all situations. They will have to deal with conflicting opinions and advice from their team, yet they must accept that they will be held accountable for the performance of their team. The surgeon–leader cannot take credit for successes while blaming failures on the team. Good teamwork and excellent communication do not relieve the leader of this responsibility.

Leadership Style

A surgeon often has a position of authority based on their titles or status in an organization that allows them to direct the actions of others. Leadership by this sort of mandate is termed “transactional leadership” and can be successful in accomplishing specific tasks. For example, a surgeon with transactional leadership skills can successfully lead a surgical team through an operation by requesting information and issuing directives. However, a leader will never win the hearts of the team in that manner. The team will not be committed and follow through unless they are empowered and feel they are truly heard. A transformational leader is one who inspires each team member to excel and to take action that supports the entire group. If the leader is successful in creating a genuine atmosphere of cooperation, less time will be spent giving orders and dealing with undercurrents of negativity. This atmosphere can be encouraged by taking the time to listen and understand the history behind its discussion. Blame should be avoided. This will allow the leader to understand the way an individual thinks and the group processes information to facilitate the introduction of change. While leadership style does not guarantee results, the leader’s style sets the stage for a great performance. At the same time, they should be genuine and transparent. This invites the team members to participate, creating an emotional connection. Leaders try to foster an environment where options are sought that meet everyone’s desires.

Conflict Management

Conflict is pervasive, even in healthy, well-run organizations and is not inherently bad. Whether conflict binds an organization together or divides it into factions depends on whether it is constructive or destructive. A good leader needs to know that there are four essential truths about conflict. It is inevitable, it involves costs and risks, the strategies we develop to deal with the conflict can be more damaging than the conflict itself, and conflict can be permanent if not addressed. The leader must recognize the type of conflict that exists and deal with the conflict appropriately. Constructive discussion and debate can result in better decision making by forcing the leader to consider other ideas and perspectives. This dialog is especially helpful when the leader respects the knowledge and opinions of team members with education, experience, and perspective different from the leader’s. Honesty, respect, transparency, communication, and flexibility are all elements that a leader can use to foster cohesion while promoting individual opinion. The leader can create an environment that allows creative thinking, mutual problem solving, and negotiation. These are the hallmarks of a productive conflict. Conflict is viewed as an opportunity, instead of something to be avoided.

Communication Skills

Communication is the primary tool of a successful leader. On important topics, it is incumbent on the leader to be articulate, clear, and compelling. Their influence, power, and credibility come from their ability to communicate. Research has identified the primary skills of an effective communicator. They are set out in the LARSQ model: Listening, Awareness of Emotions, Reframing, Summarizing, and Questions. These are not set in a particular order, but rather should move among each other freely. In a significant or critical conversation, it is important for a leader to listen on multiple levels. The message, body language, and tone of voice all convey meaning. You cannot interrupt or over-talk the other side. They need an opportunity to get their entire message out. Two techniques that enhance listening include pausing and the echo statement. Pausing before speaking allows the other conversant time to process what they have said to make sure the statement is complete and accurate. Echo statements reflect that you have heard what has been said and focuses on a particular aspect needing clarification. Good listening skills assure that the leader can get feedback that is necessary for success.

Vision, Strategy, Tactics, and Goals

One of the major tasks of a leader is to provide a compelling vision, an overarching idea. Vision gives people a sense of belonging. It provides them with a professional identity, attracts commitment, and produces an emotional investment. A leader implements vision by developing strategy that focuses on specific outcomes that move the organization in the direction of the vision. Strategy begins with sorting through the available choices and prioritizing resources. Through clarification, it is possible to set direction. Deficits will become apparent and a leader will want to find new solutions to compensate for those shortfalls. For example, the vision of a hospital is to become a world class health care delivery system. Strategies might include expanding facilities, improving patient satisfaction, giving the highest quality of care, shortening length of hospital stay with minimal readmissions, decreased mortality, and a reduction in the overall costs of health care. Tactics are specific behaviors that support the strategy with the aim to achieve success. Tactics for improving patient satisfaction may include reduced waiting time, spending more time with patients, taking time to communicate in a manner that the patient understands, responding faster to patient calls, etc. These tactics will then allow a leader to develop quantitative goals. Patient satisfaction can be measured. The surgical leader can then construct goals around each tactic, such as increasing satisfaction in specific areas. This information allows a surgical leader to identify barriers and they can take steps to remedy problem areas. This analysis helps a leader find the weakest links in their strategies as they continue toward achieving the vision.

Change Management

The world of health care is in continuous change. The intense rate of political, technical, and administrative change may outpace an individual’s and institution’s ability to adapt. Twenty-first century health care leaders face contradictory demands. They must navigate between competing forces. Leaders must traverse a track record of success with the ability to admit error. They also must maintain visionary ideas with pragmatic results. Individual accountability should be encouraged, while at the same time facilitating teamwork. Most leaders do not understand the change process. There are practical and psychological aspects to change. From an institutional perspective, we know that when 5% of the group begins to change, it affects the entire group. When 20% of a group embraces change, the change is unstoppable.

Succession Planning and Continuous Learning

An often-overlooked area of leadership is planning for human capital movement. As health care professionals retire, take leaves of absences, and move locations, turmoil can erupt in the vacuum. Leaders should regularly be engaging in activities to foster a seamless passing of institutional knowledge to the next generation. They also should seek to maintain continuity to the organization. Ways to accomplish this include senior leaders actively exposing younger colleagues to critical decisions, problem solving, increased authority, and change management. Leaders should identify promising future leaders, give early feedback for areas of improvement, and direct them toward available upward career tracks. Mentoring and coaching help prepare the younger colleagues for the challenges the institution is facing. Teaching success at all levels of leadership helps create sustainable high performance.

Visão Crítica de Segurança (Colecistectomia)

A colecistectomia laparoscópica (CL) é o padrão-ouro para tratamento de cálculos biliares. No entanto, o risco de lesão do ducto biliar (BDI) continua a ser preocupação significativa, uma vez que CL ainda tem taxa de BDI maior do que a via laparotômica, apesar de muitos esforços propostos para aumentar sua segurança.

A Visão Crítica da Segurança (CVS) proposta por Strasberg é a técnica para a identificação dos elementos críticos do triângulo de Calot durante a CL. Esta técnica foi adotada em vários programas de ensino e com a proposta de reduzir o risco de BDI e o uso da adequado da CVS está associado a menores taxas de BDI. O objetivo deste #Webinar é abordar a Anatomia Cirúrgica Fundamental para a realização de uma Colecistectomia Laparoscópica.

Subtotal cholecystectomy for difficult acute cholecystitis

Laparoscopic cholecystectomy is considered the gold standard for treatment of benign gallbladder diseases. Cholecystectomy using this method can be completed in 90% of elective cholecystectomies and 70% of emergency cholecystectomies. Acute cholecystitis, especially if difficult, can change the above paradigm, resulting in open conversion or change of technique. The conditions that define a difficult cholecystectomy are as follows: necessity of conversion from laparoscopic to open surgery; duration of procedure greater than 180 min; blood loss greater than 300 ml; and urgent need for involvement of a more experienced surgeon. One of the “rescue” procedures to complete the surgery safely (both for the surgeons and patients) is subtotal cholecystectomy (STC). Open and laparoscopic subtotal cholecystectomy have been reported. For many surgeons, this is considered a bail out technique, and the timing of decision making is crucial to avoid catastrophic complications. Te capability to perform STC in laparoscopy is increasingly requested during difficult laparoscopic cholecystectomy. Difficult LC has a risk of BDI from 3 to 5 times higher in laparoscopy than open surgery. In case of operative difficulties of young surgeons mostly trained in laparoscopy the help of senior surgeons is strongly recommended. The purpose of the present study is to clarify how laparoscopic subtotal cholecystectomy may be used to complete a difficult cholecystectomy for acute cholecystitis without serious complications.

Personal Data

Biliary leakage represents the most frequent complication of incomplete resection of the gallbladder wall in cases of difficult acute cholecystectomy treated with subtotal cholecystectomy. This complication is rarely fatal but requires correct treatment. If bile leakage does not stop spontaneously seven days postoperatively, the possible treatments are endoscopic biliary sphincterotomy, endoscopic plastic stent, and a fully covered self-expanding metal stent. When performing closure of the gallbladder stump, suturing the anterior residual of both anterior and posterior wall represents the best method to have fewer complications. Complications, if not lethal, decrease the patient’s quality of life. Intraoperatively, it is of utmost importance to carefully expose the gallbladder stump to avoid left-in-place stones, wash the entire cavity and drain the abdomen. Bile duct injuries can be a significant complication in this type of surgery. Prevention of the lesions with conversion from laparoscopic to open, or the opinion of older surgeon in case of difficulties is strongly recommended. Mortality is a very rare complication. The limitations of our study are given by the heterogeneity of the techniques used for LSC and the lack of a long-term follow-up analyzing the related complications.

Liver Disease and Perioperative Risk

The liver is the biggest intestinal organ and plays a central role in the homeostasis of different physiological systems including nutrition and drug metabolism, the synthesis of plasma proteins and haemostatic factors, as well as the elimination of different endogenous and exogenous substances. Although the liver contributes with only 3% to total body weight, given its major role in homeostasis and high energy consumption, it receives 25% of total cardiac output (CO). Two vessels contribute to the perfusion of the liver. The majority (70%) of the hepatic perfusion is provided by the portal vein, which contributes 50% of the organ’s oxygen demand. The other 50% is provided by the hepatic artery, which makes up around 30% of total liver perfusion. Hepatic arterial blood flow is mainly dependent on the organ’s metabolic demands and controlled via autoregulatory mechanisms, whereas blood supply through the portal vein depends on the perfusion throughout the whole gastrointestinal tract and the spleen. This unique, dual perfusion system provides constant perfusion rates and oxygen supply, which is crucial for adequate liver function. These high oxygen demands are reflected in a hepatic vein saturation of almost 30%.

The liver is also unique in its ability of regeneration, which allows the performance of major surgery including, amongst others, extended resections of liver tumours, living donations and so on. Many patients have normal liver function parameters when they present for liver surgery, especially when the reason for resection is metastasis or a benign liver tumour. The most common causes of liver resections are the hepatocellular carcinoma (HCC) and the cholangiocellular carcinoma (CCC). Hepatocellular carcinoma (HCC) often develops in patients with underlying liver cirrhosis; many of these patients show signs of chronic liver dysfunction (CLD).

As explained previously, the liver plays a central role in a great deal of physiological systems. Therefore, in case of chronic liver dysfunction (CLD) or liver failure, several effects on other organ systems have to be expected. Consequently liver resections and bile duct surgery as having a high risk for perioperative cardiac events, with an estimated 30-day cardiac event rate (cardiac death and myocardial infarction) of more than 5%. Patients undergoing liver surgery pose a significant challenge to treating physicians in the perioperative period. Due to the improvement of surgical techniques, the “liver patient” is becoming more and more complex, confronting surgeons, anaesthetists and intensive care personnel with difficult intra- and postoperative courses, and considerable multiorgan disorders. The cornerstones of an optimal management are careful selection of the patients, appropriate monitoring and protection of the liver and other vital organs.

“Not Only SURGEONS…”

Not Only Surgeons

SURGERY, A NOBLE PROFESSION

Surgery is, indeed, one of the noblest of professions. Here is how Dictionary defines the word noble: 1) possessing outstanding qualities such as eminence, dignity; 2) having power of transmitting by inheritance; 3) indicating superiority or commanding excellence of mind, character, or high ideals or morals. These three attributes befit the profession of surgery. Over centuries, the surgical profession has set the standards of ethical and humane practice. Surgeons have made magnificent contributions in education, clinical care, and science. Their landmark accomplishments in surgical science and innovations in operative technique have revolutionized surgical care, saved countless lives, and significantly improved longevity and the quality of human life. Generations of surgeons have developed their craft and passed it on to succeeding generations, as they have to me and to each one of you, to take into the future.

Beyond its scientific and technical contributions, surgery is uniquely fulfilling as a profession. It has disciplined itself over the centuries and dedicated its practice to the best welfare of all human beings. In return, it has been accorded the respect of society, of other professions, and of policy makers. Its conservative stance has served it well and has been the reason for its constancy and consistency. At the beginning of the 21st century, however, profound changes are taking place at all levels and at a dizzying pace, providing both challenges and opportunities to the surgical profession. These changes are occurring on a global level, on the national level, in science and technology, in healthcare, and in surgical education and practice.

To retain its leadership position in innovation and its attractiveness as a career choice for students, surgery must evolve with the times. It is my belief that surgery needs to introduce changes to create new priorities in clinical practice, education, and research; to increase the morale and prestige of surgeons; and to preserve general surgery as a profession. I am reminded of a Chinese aphorism that says, “You cannot prevent the birds of unhappiness from flying over your head, but you can prevent them from building a nest in your hair.”

ADVANCES IN SCIENCE

The coalescence of major advances in science and technology made the end of the 20th century unique in human history. Notable among the achievements are the development of microchips and miniaturization, which fueled the explosion in information technology. The structure of the human genome is nearly completely elucidated, ushering in the genomic era in which genetic information will be used to predict, on an individual basis, susceptibility to disease and responsiveness to drug therapy. The field of nanotechnology allows scientists to work at a resolution of less than one nanometer, the size of the atom. By comparison, the DNA molecule is 2.5 nanometers.

In the last 50 years, biomedical research became increasingly reductionist, turning physiologists and anatomists into molecular biologists. As a result, two basic science fields—integrative physiology and gross anatomy—now have a lower standing in medical education and surgical science than they once did. Surgery and surgical departments can and possibly should claim these fields, but the window of opportunity is narrow. Research is now moving back from discipline-based reductionist science to multidisciplinary science of complexity, in which biomedical scientists work side by side with engineers, mathematicians, and bioinformatists. The ability of high-speed computers to quickly process tens of millions of pieces of data now allows for data-driven rather than hypothesis-based research. This collaboration among different disciplines has already been successful.

TRANSFORMATION OF HEALTHCARE SYSTEM

During the past 75 years, we have seen the entire healthcare system undergo a profound transformation. In the 1930s and for a considerable period thereafter, medical practice was fee-for-service, the doctor–patient relationship was strong, and the physician perceived himself or herself as being responsible nearly exclusively to his or her individual patients. The texture of medical practice started to change when the federal government became involved in the provision of healthcare in 1965. The committee on “Crossing the Quality Chasm” identified six key attributes of the 21st-century healthcare system. It must be:

  1. Safe, avoiding injuries to patients;
  2. Effective, providing services based on scientific knowledge;
  3. Patient-oriented, respectful of and responsive to individual patients’ needs, values, and preferences;
  4. Timely, reducing waits, eliminating harmful delays for both care receiver and caregiver;
  5. Efficient, avoiding wasted equipment, supplies, ideas, and energy;
  6. Equitable, providing equal care across genders, ethnicities, geographic locations, and socioeconomic strata;

No one knows at present what this 21st-century healthcare system will look like. While care in the old system was reactive, in the new system it will be proactive. The “find it, fix it” approach of the old system will be replaced by a “predict it, prevent it, and if you cannot prevent it, fix it” approach. Sporadic intervention, provided only when patients present with illness, will give way to a system in which physicians and other healthcare providers plan 1-, 5-, and 10-year care programs for each patient. Care will be more interactive, with patients taking a more important role in their own care. The technology-oriented system will become a system that provides graded intervention. Delivery systems will not be fractionated but integrated. Even more importantly, care will not be based simply on experience and clinical impression but on evidence of proven outcome measures. If the old system was cost-insensitive, the new system will be cost-sensitive.

SURGICAL PRACTICE

There are many reasons for the declining interest in general surgery, some of which parallel reasons for the drop in medical school applicants in general. One problem specific to surgery is that medical students are given less and less exposure to surgery, due to the shortening of required surgical rotations. Most important, however, is their perception that the life of the surgical resident is stressful, the work hours too long, and the time for personal and family needs inadequate. The workload of the surgical resident over the years has increased significantly both in amount and intensity, without concomitant increase in the number of residents and at a time when hospitals have significantly reduced the support personnel on the surgical ward and in the operating rooms. Students graduating with debts close to $100,000 simply find the years of training in surgery too long, followed by uncertain practice income after graduation.

From several recent studies, lifestyle is the critical and most pressing issue in surgical residency. Some studies have also shown that the best students tend to select specialties that provide controllable lifestyles, such as radiology, dermatology, and ophthalmology. We have a problem not only in the declining number of students applying for surgical training but also in the declining quality of those who do apply. In a preliminary survey of 153 responding general surgery programs, we found that attrition (i.e., categorical residents leaving the training programs) occurred at a rate of 13% to 19% in the last 5 years. In 2001, 46% of those leaving general surgery training programs cited lifestyle as the major reason.

Unless these trends are reversed, general surgery as a specialty is threatened, and a future shortage of general surgeons is inevitable. I know that the Council of the American Surgical Association is most concerned about the crisis in general surgery. We must do a better job of communicating to students and residents that the practice of surgery is as rewarding as ever and full of opportunities in this new era. Innovations in minimal access and computer-assisted surgery and simulation technology provide exciting new possibilities in surgical training. We must also look very carefully at the demands of surgical residency and improve the life of residents without compromising their surgical experience. Unless we deal with work hours and quality of life issues, we are likely to see continuing decline in the interest of medical students in surgical training.

CONCLUSIONS

In conclusion, the noble profession of surgery must rise to meet numerous challenges as the world in which it operates continues to undergo profound change. These challenges represent opportunities for the profession to develop an international perspective and a global outreach and to address the growing needs of an aging population undergoing major demographic and workforce shifts. The leadership of American surgery has a unique role to play in the formulation of a new healthcare system for the 21st century. This task will require commitment to quality of care and patient safety, and it will depend on harnessing the trust and support of the American public. Advances in science and technology—particularly in minimal access surgery, robotics, and simulation technology—provide unprecedented opportunity for surgeons to continue to make landmark contributions that will improve surgical care and the human condition. I believe it is also crucially important that we train surgeon-scientists who will keep surgery at the cutting edge in the genomic and bioinformatics era. Ours is a noble profession imbued with eminence, dignity, high ideals, and ethical values. It has a rich and proud heritage… and I quote, “The highest intellects, like the tops of mountains, are the first to catch and reflect the dawn.”

Surgical Management of PANCREATIC CANCER

INTRODUCTION

Pancreatic ductal adenocarcinoma (PDAC) carries one of the poorest overall prognosis of all human malignancies. The 5-year survival in patients with PDAC, for all stages, remains as low as 6–7%. The low survival rate is attributed to several factors, of which the two most important are aggressive tumor biology and late stage at which most patients are diagnosed. Only 10–20% of patients are eligible for resection at presentation, 30–40% are unresectable/locally advanced, and 50–60% are metastatic. Pancreatic cancer without distant metastasis can be divided into three categories: resectable, borderline resectable, and locally advanced. In absence of metastatic disease, the most important factor for improving survival and possibly offer cure is to achieve a margin-negative resection. Even after potential curative resection, most patients develop recurrences eventually, and 5-year survival of completely resected patients is only up to 25%. The aggressive tumor biology and its inherent resistance to chemotherapy and radiotherapy contributes to early recurrence and metastasis.

SURGICAL ADVANCES

Pancreatic cancer surgery has evolved over the past few decades and remains the cornerstone of treatment of resectable and borderline resectable tumors. Advances in modern imaging give precise information on disease extension and vascular involvement that aids in surgical planning in order to achieve a margin-negative resection.

SURGICAL TECHNIQUES

Surgical techniques for pancreatic cancer include pancreaticoduodenectomy, distal pancreatectomy with splenectomy, and total pancreatectomy. Standard lymphadenectomy for pancreatoduodenectomy should include removal of lymph node stations 5, 6, 8a, 12b1, 12b2, 12c, 13a, 13b, 14a, 14b, 17a, and 17b. Involvement of superior mesenteric vein (SMV)/portal vein(PV) was previously considered as a contraindication for resection. However, curative resection along with SMV/PV with vascular reconstruction has now become a standard practice in specialized high-volume centers. To improve margin-negative resections, specially in borderline resectable tumors with proximity to vascular structures, SMA first approach was proposed as a new modification of standard pancreatico-duodenectomy. In a systematic review, SMA first approach was shown to be associated with better perioperative outcomes, such as blood loss, transfusion requirements, pancreatic fistula, delayed gastric emptying, and reduced local and metastatic recurrence rates. In case of arterial involvement, there is no good evidence at present to justify arterial resections for right-sided pancreatic tumors. However, the modified Appleby procedure, which includes en bloc removal of celiac axis with or without arterial reconstruction, when used in appropriately selected patients, offers margin negative resection with survival benefit for locally advanced pancreatic body and tail tumors and should be performed in high-volume centers. Most evidence does not support advantage of more extended resections such as removal of the para-aortic lymph nodes and nerve plexus and multivisceral resections routinely. Such extended resections are associated with compromised quality of life because of associated higher perioperative morbidity and intractable diarrhea. However, in highly selected patients, with preserved performance status and stable or nonprogressive disease on neoadjuvant treatment, such extended resections can provide survival advantage over palliative treatments. Radical surgery in the presence of oligometastatic disease has also been reported to prolong survival in highly selected patients.

Surgical Management of CHOLANGIOCARCINOMA

#thesurgeon

Cholangiocarcinoma is an uncommon cancer that occurs within the intrahepatic and extrahepatic portions of the bile duct system. In North America, the incidence of extrahepatic cholangiocarcinoma is 0.5–2 per 100,000 and 0.95 per 100,000 for intrahepatic cholangiocarcinoma. Up to 50% of patients will be lymph node (LN) positive at presentation, 5% are multifocal tumors, and 10–20% will have peritoneal involvement at presentation. Risk factors for cholangiocarcinoma are primary sclerosing cholangitis (PSC) with a lifetime risk 10–40%, parasitic infection, previous sphincteroplasty, congenital anomalies of the biliary tree (choledochal cyst, Caroli’s disease, anomalous pancreaticobiliary duct junction), and chronic biliary inflammatory disease (hepatitis B/C, liver cirrhosis, recurrent pyogenic cholangitis). The most common presentation is painless jaundice and weight loss in the setting of extrahepatic duct involvement. In Western countries, 80% are extrahepatic (20% distal and 60% hilar) and 20% are intrahepatic.

SPECIAL NOTES

Ca 19–9 can be elevated in up to 85% of patients with cholangiocarcinoma, but is not specific; elevation can also occur in the setting of obstructive jaundice without malignancy. If it remains elevated after biliary decompression, it could indicate the presence of malignancy. Elevated pre- and postoperative Ca 19–9 predict poor survival.
• For perihilar tumors, decisions regarding which side of the liver to resect depend on right- or left-sided dominance, volume of future liver remnant, and the extent of vascular and ductal involvement.
• Some centers report that 30–50% of tumors will be deemed unresectable at the time of surgery, despite accurate preoperative imaging.
• Quality Indicators: Pathologic Analysis—R0 margin, regional lymphadenectomy includes three or more LN.

SURGICAL MANAGEMENT

Intrahepatic cholangiocarcinoma: Surgical resection is the only potential cure with removal of involved liver segments. There is emerging evidence that recommends a routine hilar LN and dissection for its prognostic value, M1 disease includes involvement of celiac,periaortic or caval LN.

Distal bile duct (below the cystic duct): Surgical resection is the only potential cure. Pancreaticoduodenectomy including en bloc resection of extrahepatic bile duct and gallbladder. Regional nodes include: Hilar (CBD, common hepatic, portal, cystic), Posterior and anterior pancreaticoduodenal Nodes along SMV, Nodes along right and lateral wall of SMA.

Hilar (above the cystic duct): En bloc resection of extrahepatic bile duct and gallbladder, including right and left hepatectomy, or extended right/left hepatectomy, Caudate lobe should be removed. Regional nodes include: Hilar (CBD, hepatic,portal, cystic), Pericholedochal nodes in hepatoduodenal ligament.

Ao Cadáver DESCONHECIDO

Hic locus est ubi mors gaudet succurrere vitae

“É este o lugar onde a morte se alegra de socorrer a vida”

Égide do respeito ao Cadáver no estudo da Anatomia Humana*.

A utilização do cadáver representa uma tríplice lição educativa:

  1. Instrutiva/Informativa: como meio de conhecimento da organização do corpo humano, procedendo ao estudo no vivo;
  2. Normativa/Disciplinadora: através do seu caráter metodológico e de precisão técnica da linguagem;
  3. Estético/Moral: pela natureza do material de estudo, o cadáver, e pelo método primeiro de aprendizado, a dissecção, que é experiência e trabalho repousante na contemplação da beleza e harmonia de construção do organismo humano.

Contudo e essencialmente, porém, lição de ética e de humildade, porque:

  1. Não é o cadáver, doado ou indigente, fato isolado da comunidade, mas seu reflexo, dela provindo. O cadáver que é o meio de aprendizado para adequada assistência do vivo, assim portanto tão importante para a sociedade como o é o paciente;
  2. Esses corpos sem vida são vivificados de forma reiteradas pelo calor da juventude estudiosa através do sentimento de gratidão; O cadáver, antes de tudo “um irmão em Humanidade, se entrega despojadamente ao conhecimento que proporciona aos futuros profissionais, de maneira anônima oriunda do jogo do acaso da vida;
  3. O cadáver anônimo ao receber este título – cadáver desconhecido – e assim ultrapassar o limite estreito de um nome e, despersonalizado, distribui elementos para o bem coletivo, sem ter conhecimento quer antes, durante ou depois de sua imolação, do seu destino a um tempo sublime e sagrado;
  4. O Cadáver desconhecido tudo oferece ao conhecimento sem nada haver recebido daquele que o estuda, que dá sem saber que dá e por isso, sem conhecer recompensa da gratidão e sem sentimento do valor  da sua dádiva generosa, na mais nobre expressão de poderosa caridade universal;
  5. O cadáver que dissecado, desmembrado, simboliza outra forma de crucificação para o bem comum e marca o sentido profundamente humano da Medicina;

Portanto o nosso material de estudo transcende pois ao simples valor de meio e objeto de aprendizado; e nos fala em linguagem universal que nos educa na humildade da limitação humana. Eis porque na austeridade do ambiente do Laboratório de Anatomia a atitude física, mental e verbal do aluno deve ser de sobriedade, respeito, meditação e elevada compostura, manuseando as peças anatômicas com o mais profundo sentimento de respeito e carinho.

Nulla Medicina Sine Anatomia

“Ao curvar-te sobre o cadáver desconhecido…

lembra-te que este corpo nasceu do amor de duas almas; cresceu embalado pela fé e esperança daquela que em seu seio o agasalhou, sorriu e fitou os mesmos sonhos das crianças e dos jovens; por certo amou, foi amado e também acalentou um amanhã feliz. Seu nome só Deus o sabe e agora nesta fria lousa, o destino inexorável deu-lhe o poder e a grandeza de servir a humanidade numa última missão, ENSINAR.

Ó irmão ignoto que tivestes a morada do espirito, o seu corpo, perturbado em seu repouso imutável por nossas mãos ávidas de saber, apresentamos a ti o nosso respeito permanente e infindo AGRADECIMENTO.”

COMPARATIVE STUDY BETWEEN THE SLEEVE GASTRECTOMY AND GASTRIC PLICATION IN OBESE RATS

INTRODUCTION: Obesity results from a prolonged imbalance between energy intake and energy expenditure. Studies with experimental models of bariatric surgery provided a fundamental contribution to the understanding of morphological and functional changes in obesity and after bariatric surgery. The restrictive bariatric surgery techniques currently used are gastric banding, sleeve gastrectomy and the gastric plication. The latter is considered an experimental technique and has therefore not yet enough studies that shed light on the postoperative rates of weight loss, surgical complications, resolution of comorbidities and the mechanisms responsible for weight loss. The aim of this study was to conduct a comparative study in rats with cafeteria diet-induced, between gastric plication and sleeve gastrectomy in variation late postoperative in body weight ,plasma biochemistry and gross and microscopic alterations gastric effects obesity.

MATERIAL AND METHOD: 28 male Wistar rats were randomized into three groups after induction period of obesity by cafeteria diet and underwent sleeve gastrectomy (GV group), gastric plication (GP group) and sham operation (control group). The animals were assessed daily postoperatively and the variables were recorded: (initial seven days, 14 and 21 days) body weight and presence of complications until day 21 postoperatively, when they were euthanized and evaluated: biochemistry (glucose, insulin, HDL, total cholesterol, triglycerides, AST, ALT and serum ghrelin), degree of intra-abdominal adhesions, resistance testing will air insufflation in the stomach and microscopic evaluation of the gastric mucosa.

RESULTS: In relation to body weight variation of animals GV group (initial weight: 318 ± 7.89 g / Final weight: 213 ± 9.03g) was significantly decreased (p<0.05) at 21 post-surgery day compared to the GP group (initial weight: 314.11 ± 20.79 g / final weight: 239.16 ± 14.71 g) and control (initial weight: 315.16±17.54g / final weight: 317.91±16.06 g). The animals in the GV group had a significant decrease (p<0.001) in blood glucose, insulin, transaminases, serum HDL and ghrelin compared to animals in GP and control. Was also significantly lower the burst pressure of the stomach in the GV group, the insufflation test the atmospheric air in relation to the GP and control groups. The GP and GV groups showed even different histological grade of inflammation
(subacute inflammation) and control group (chronic inflammation).

CONCLUSIONS: The sleeve gastrectomy is more effective than gastric plication weight loss, metabolic control and reduction of serum ghrelin in obesity rats, and presents the same rates of postoperative complications (adhesions, deaths and grade inflammation).

KEYWORDS: 1. Obesity; 2. Bariatric Surgery; 3.Wistar rats.

Preoperative Biliary Drainage

The most common presenting sign for patients with malignancy of the periampullary region is obstructive jaundice. While a significant proportion of these patients will be asymptomatic, the deleterious systemic consequences of uncontrolled hyperbilirubinemia may still occur. Furthermore, symptoms such as pruritus can be debilitating and have a significant impact on the quality of life. Thus, some have advocated preoperative drainage of the biliary system in patients with resectable periampullary malignancies, given widespread availability of endoscopic retrograde cholangiopancreatography and its perceived safety profile. On the other hand, the purported benefits of routine preoperative drainage in this patient population (namely, resolution of symptoms in symptomatic patients while awaiting surgery, restoration of the enterohepatic cycle, and a potential decrease in postoperative morbidity) have proven to be largely theoretical, and now there are high-quality phase III data that demonstrate the deleterious effects of routine stenting. A seminal study originating from the Netherlands in 2010 evaluated this issue in the only modern randomized controlled trial to date evaluating preoperative endoscopic biliary decompression for these patients. In their multicenter study, they randomized 202 patients with newly diagnosed pancreatic head cancer and bilirubin levels between 2.3 and 14.6 mg/dL to preoperative biliary drainage for 4–6 weeks vs. immediate surgery which was to be performed within a week of enrollment. The primary endpoint was the development of serious complications within 120 days after randomization. Serious complications were defined as complications related to the drainage procedure or the surgical intervention that required additional medical, endoscopic, or surgical management, and that resulted in prolongation of the hospital stay, readmission to the hospital, or death. The reported overall rate of serious complications in this study favored the immediate surgery group (39 vs. 74%; RR 0.54–95% [CI], 0.41–0.71; P < 0.001), complications related to surgery were equivalent (37 vs. 47%; P = 0.14), and there was no difference in mortality rates or length of hospital stay. The observed drainage-related complications included a 15% rate of stent occlusion, 30% need for exchange, and 26% incidence of cholangitis.

Based on these results, the authors concluded that the morbidity associated with the drainage procedure itself had an additive effect on the postoperative morbidity of patients undergoing pancreatic head resection for cancer and recommended against its routine use in this population.

A Cochrane systematic review of all available randomized studies (including the abovementioned study by van der Gaag et al.) evaluating preoperative biliary drainage was published in 2012. In this study, Fang et al. assessed the impact of this intervention on survival, serious morbidity (defined as Clavien-Dindo grade 3 or 4), and quality of life. Furthermore, they sought to assess differences in total length of hospital stay and cost. They identified six randomized trials of which four used percutaneous transhepatic biliary drainage and the remaining two used endoscopic sphincterotomy and stenting. The pooled analysis of 520 patients (of which 51% underwent preoperative biliary drainage) showed no difference in mortality, but importantly, it showed a significantly higher incidence of serious morbidity in the preoperative drainage group with a rate ratio (RaR) of 1.66 (95% CI 1.28–2.16;P = 0.002). There was no difference in length of hospital stay and not enough data reported for analysis of cost or quality of life.

Based on the available level 1 data, the authors concluded that there was no evidence to support or refute routine preoperative biliary drainage in patients with obstructive jaundice.

However, this review also underscored the fact that preoperative biliary drainage may be associated with an increased rate of adverse events and thus questioned the safety of this practice. This Cochrane review included old studies that evaluated patients undergoing percutaneous drainage, a technique used less frequently today for periampullary malignancies. Furthermore, several of these trials included patients with hilar and other types of biliary obstruction. However, the concept of preoperative decompression, as well as its purported benefits and observed results, may be reasonably extrapolated to patients with periampullary lesions.

Critical View Of Safety

Steven Strasberg, 2017

“The concept of the critical view was described in 1992 but the term CVS was introduced in 1995 in an analytical review of the emerging problem of biliary injury in laparoscopic cholecystectomy. CVS was conceived not as a way to do laparoscopic cholecystectomy but as a way to avoid biliary injury. To achieve this, what was needed was a secure method of identifying the two tubular structures that are divided in a cholecystectomy, i.e., the cystic duct and the cystic artery. CVS is an adoption of a technique of secure identification in open cholecystectomy in which both cystic structures are putatively identified after which the gallbladder is taken off the cystic plate so that it is hanging free and just attached by the two cystic structures. In laparoscopic surgery complete separation of the body of the gallbladder from the cystic plate makes clipping of the cystic structures difficult so for laparoscopy the requirement was that only the lower part of the gallbladder (about one-third) had to be separated from the cystic plate. The other two requirements are that the hepatocystic triangle is cleared of fat and fibrous tissue and that there are two and only two structures attached to the gallbladder and the latter requirements were the same as in the open technique. Not until all three elements of CVS are attained may the cystic structures be clipped and divided. Intraoperatively CVS should be confirmed in a “time-out” in which the 3 elements of CVS are demonstrated. Note again that CVS is not a method of dissection but a method of target identification akin to concepts used in safe hunting procedures. Several years after the CVS was introduced there did not seem to be a lessening of biliary injuries.

Operative notes of biliary injuries were collected and studied in an attempt to determine if CVS was failing to prevent injury. We found that the method of target identification that was failing was not CVS but the infundibular technique in which the cystic duct is identified by exposing the funnel shape where the infundibulum of the gallbladder joins the cystic duct. This seemed to occur most frequently under conditions of severe acute or chronic inflammation. Inflammatory fusion and contraction may cause juxtaposition or adherence of the common hepatic duct to the side of the gallbladder. When the infundibular technique of identification is used under these conditions a compelling visual deception that the common bile duct is the cystic duct may occur. CVS is much less susceptible to this deception because more exposure is needed to achieve CVS, and either the CVS is attained, by which time the anatomic situation is clarified, or operative conditions prevent attainment of CVS and one of several important “bail-out” strategies is used thus avoiding bile duct injury.

CVS must be considered as part of an overall schema of a culture of safety in cholecystectomy. When CVS cannot be attained there are several bailout strategies such a cholecystostomy or in the case of very severe inflammation discontinuation of the procedure and referral to a tertiary center for care. The most satisfactory bailout procedure is subtotal cholecystectomy of which there are two kinds. Subtotal fenestrating cholecystectomy removes the free wall of the gallbladder and ablates the mucosa but does not close the gallbladder remnant. Subtotal reconstituting cholecystectomy closes the gallbladder making a new smaller gallbladder. Such a gallbladder remnant is undesirable since it may become the site of new gallstone formation and recurrent symptoms . Both types may be done laparoscopically.”

Mirizzi’s Syndrome

INTRODUCTION

First described by Pablo Mirizzi in 1948 as “functional hepatic syndrome”, Mirizzi’s syndrome was initially thought to be the result of a “physiologic sphincter” of the hepatic duct. It is now understood to be a result of mechanical obstruction of the common hepatic duct secondary to an impacted stone in the gallbladder neck, Hartmann’s pouch, or the cystic duct. The syndrome is very uncommon in Western populations with a reported prevalence of 0.05%-5.7% in large modern series of patients undergoing biliary surgery. With chronic stone impaction, inflammation and recurrent cholangitis can develop with subsequent erosion into the common bile duct (CBD) and resultant biliobiliary fistula between the gallbladder and CBD.

CLASSIFICATION

The syndrome encompasses a spectrum of disease. Broadly speaking, Mirizzi’s syndrome can be grouped into two major categories: (1) external compression of the CBD without a fistula (Type 1), and (2) erosion into the CBD causing a cholecystobiliary fistula (Type II-IV). Csendes classification is currently being used to reflect the above classification. Retrospective studies have identified an association between Mirizzi’s syndrome and gallbladder cancer, with an incidence as high as 28%, relative to an incidence of 1-2% in patients with uncomplicated gallstone disease. As with other malignant processes of the biliary tract, biliary stasis and chronic inflammation have been suggested to play a role. In general, it is difficult to distinguish benign Mirizzi’s syndrome from a neoplastic process preoperatively, although older patient age, significantly elevated Ca 19-9, and imaging features suggestive of invasion into the liver or a mass filling the gallbladder should raise suspicion for malignancy.

CLINICAL FINDS
The most common presenting symptoms are right upper quadrant pain, jaundice, nausea/vomiting, and fever. This spectrum of findings overlaps with several other pathologic processes of the hepatobiliary tract, making preoperative diagnosis difficult. Additionally, the clinical picture may be complicated by the concurrent presence of acute cholecystitis, pancreatitis, or even gallstone ileus. Mirizzi’s syndrome should be suspected in any patient presenting with right upper quadrant pain and abnormal liver enzymes (particularly elevated bilirubin and alkaline phosphatase) or imaging suggestive of an impacted stone. Three findings on imaging together suggest a diagnosis of Mirizzi’s: 1) dilation of the biliary system above the level of the gallbladder neck, 2) the presence of a stone impacted in the gallbladder neck, and 3) an abrupt change to a normal width of the common duct below the level of the stone. Such findings should prompt further imaging to better define the biliary tree, either indirectly though magnetic resonance cholangiopancreatography (MRCP), or directly through endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography (PTC). No imaging modality is entirely sensitive for Mirizzi’s syndrome and the key is to maintain a high index of suspicion.

MANAGEMENT

Management of Mirizzi’s syndrome depends on the degree of fistula. In Type I disease, laparoscopic cholecystectomy is usually achievable, either total (classic) or subtotal, depending on the specific intraoperative findings. If the view of safety can be attained with the critical structures isolated, a classic cholecystectomy may be performed. If the view of safety cannot be achieved due to inflammation or adhesions, the gallbladder is taken down retrograde and opened near the cystic duct orifice. All stones are removed, including any impacted stones, and the cystic duct orifice is examined for the presence of bile to determine whether it is patent. If the cystic duct is patent, it should be ligated (if possible), or the remnant gallbladder should be sutured closed over it (choledochoplasty). An external closed suction drain may be left in the gallbladder fossa and removed the following day if drainage is non-bilious. More commonly, the cystic duct is obliterated, and a subtotal cholecystectomy with removal of all stones is sufficient.

Management of Mirizzi’s syndrome in the presence of a biliobiliary fistula is more complex. If the fistula involves <1/3 of the CBD circumference (Type II), options include primary repair using absorbable suture, closure over a T-tube, or choledochoplasty using the remnant gallbladder. The last approach is preferable to maintain the diameter of the CBD and minimize the risk of subsequent stricture but requires that sufficient gallbladder remnant be available to allow closure. In the presence of a more extensive fistula (Type III or IV), bilioenteric anastomosis is usually the best option.

Transplantation for nonalcoholic steatohepatitis

INTRODUCTION

The global obesity epidemic has dramatically increased the prevalence of NAFLD and made it the leading cause of chronic liver disease in Western nations. NAFLD is considered the hepatic manifestation of the metabolic syndrome and shares a strong association with type 2 diabetes mellitus, obstructive sleep apnea (OSA), and cardiovascular disease. Although cardiovascular disease is the leading cause of death in patients with NAFLD, the subset of patients who meet histopathologic criteria for NASH are those at greatest risk of liver-related morbidity and mortality. Ludwig and colleagues coined the term NASH in 1980 to describe a cohort of middle-aged patients with elevated serum liver enzyme levels who had evidence of alcohol-associated hepatitis on biopsy specimens in the absence of alcohol consumption. Subsequent study led to the proposed “2-hit” hypothesis in which a sequential progression from isolated fatty liver (IFL) to NASH involved the initial “hit” of hepatic steatosis followed by a second “hit” of oxidative stress resulting in liver injury. It was subsequently recognized that patients who have steatohepatitis on a liver biopsy specimen are at greatest risk for progression to cirrhosis compared with those who have IFL. Correspondingly, our understanding of the pathogenesis of NAFLD has evolved from the 2-hit hypothesis. NASH is expected to become the most common cause of cirrhosis and the leading indication for LT in the USA in the 2020s. As a major public health concern, an understanding of its epidemiology and pathogenesis is paramount to facilitate our ability to effectively diagnose and treat patients with NAFLD and NASH.

EPIDEMIOLOGY

NAFLD is an increasingly frequent cause of cirrhosis and HCC. In fact, a report published in 2018 listed NAFLD as the second leading non-neoplastic indication for LT in adults in the USA, following alcohol-associated liver disease. Obesity (BMI ≥30 kg/m2) and type 2 diabetes mellitus are commonly encountered in patients with NAFLD; these 2 diseases have been recognized as risk factors for HCC, irrespective of the presence or etiology of cirrhosis. Although BMI is not necessarily a reliable indicator of adiposity in patients with end-stage liver disease, particularly in those with fluid retention and ascites, it is commonly used by many LT centers during the patient selection process. Morbid obesity (BMI ≥40 kg/m2 without significant obesity-related comorbidities or BMI ≥35 kg/m2 associated with obesity-related comorbidities) is commonly regarded as a relative contraindication to LT; however, data from the Organ Procurement and Transplantation Network demonstrate that 16.5% and 5% of patients who underwent LT in 2016 had a BMI greater than or equal to 35 kg/m2 and greater than or equal to 40 kg/m2, respectively.

NAFLD and Liver Transplantation

Analysis of data from the UNOS registry has suggested that the risk of primary graft nonfunction is increased and short- and long-term survival is poorer in morbidly obese liver transplant recipients with various causes of end-stage liver disease. However, when analyzed as an entire cohort and not stratified by BMI, patients with NAFLD have patient and graft survival rates that are comparable to those for other indications for LT. Many of the key precipitants of NAFLD (obesity, hyperlipidemia, and insulin resistance) are exacerbated by immunosuppression. Recurrence of NAFLD after LT causes graft injury, although graft loss does not typically occur. De novo NAFLD after LT has also been described. In the absence of specific therapy for NAFLD, therapeutic efforts after LT should center on weight control, optimal diabetic management, and use of a lipid-lowering agent, if indicated. Intensive noninvasive weight loss interventions pre-LT appear to be successful (reduction of BMI to <35 kg/m2) in a large proportion of patients (84%) enrolled in carefully monitored multidisciplinary protocols; however, 60% of patients regained weight to a BMI ≥35 kg/m2 post-LT. Although bariatric surgery is feasible in selected patients with NAFLD, this intervention is typically reserved for patients with early stages of liver disease and, as is the case for many other abdominal surgical procedures, is contraindicated in those with decompensated cirrhosis because of high morbidity and mortality. A strategy of combining LT with sleeve gastrectomy during the same operation has only been evaluated in small prospective series. The mean surgical time was not significantly different between LT and combined LT/sleeve gastrectomy, and the mean BMI reduction with the combined surgical approach was 20 kg/m2. Metabolic complications, such as post-transplant diabetes mellitus, as well as steatosis of the graft noted by US were significantly less frequent in patients undergoing LT/sleeve gastrectomy compared with patients who lost weight noninvasively pre-LT. The safety and efficacy of this combined surgical approach and other combinations of less invasive weight loss interventions, such as endoscopic techniques, pre-LT must be confirmed by large prospective studies before they can be recommended. Bariatric interventions are still an option post-LT; however, the procedure should be performed by an experienced surgeon, and the role of less invasive endoscopic techniques postLT is still under investigation.

Sleeve Gastrectomy vs NAFLD

Bariatric surgery leads to substantial weight loss that results in improved metabolic parameters and hepatic histology in patients with NAFLD, according to numerous large retrospective and prospective cohort studies. In one study of 109 patients with NASH who underwent follow-up liver biopsy one year after bariatric surgery, 85% of patients had resolution of NASH, and 33% had improvement in fibrosis. Initial concerns that fibrosis would worsen with rapid weight loss were unfounded, as demonstrated in a meta-analysis in which fibrosis improved by 11.9% from baseline after bariatric surgery. Although bariatric surgery is not recommended as a treatment for NASH, the abundant positive data in its favor suggest that surgical weight loss is a viable option for patients with comorbid conditions that would warrant the surgery for other reasons. Patients with NASH cirrhosis are at potentially higher risk for surgical complications, although some centers have demonstrated encouraging results with sleeve gastrectomy in patients with Child-Pugh class A cirrhosis.

Laparoscopic Liver Resection

INTRODUCTION

Laparoscopic hepatic resection is an emerging option in the field of hepatic surgery. With almost 3000 laparoscopic hepatic resections reported in the literature for benign and malignant tumors, with a combined mortality of 0.3% and morbidity of 10.5%, there will be an increasing demand for minimally invasive liver surgery. Multiple series have been published on laparoscopic liver resections; however, no randomized controlled trial has been reported that compares laparoscopic with open liver resection. Large series, meta-analyses, and reviews have thus far attested to the feasibility and safety of minimally invasive hepatic surgery for benign and malignant lesions.

THECNICAL ASPECTS

The conversion rate from a laparoscopic approach to an open procedure was 4.1%. The most common type of laparoscopic liver resection performed is a wedge resection or segmentectomy (45%), followed by left lateral sectionectomy (20%). Major anatomic hepatectomies are still less frequently performed: right hepatectomy (9%) and left hepatectomy (7%). Cumulative morbidity and mortality was 10.5% and 0.3%.

Laparoscopic Left Hepatectomy

BENEFITS OF LAPAROSCOPIC APPROACH

More importantly, almost all the studies comparing laparoscopic with open liver resection consistently showed a significant earlier discharge to home after laparoscopic liver resection. Lengths of stay were variable based on the country of origin of the studies but were consistently shorter for laparoscopic liver resection. Three studies published in the United States presented a length of stay of 1.9 to 4.0 days after laparoscopic liver resection. Studies from Europe showed an average length of stay of 3.5 to 10 days whereas those from Asia reported an average of length of stay of 4 to 20 days after laparoscopic liver resection.

COST ANALYSIS

Vanounou and colleagues used deviation-based cost modeling to compare the costs of laparoscopic with open left lateral sectionectomy at the University of Pittsburgh Medical Center. They compared 29 laparoscopic with 40 open cases and showed that patients who underwent the laparoscopic approach faired more favorably with a shorter length of stay (3 vs 5 days, P<.0001), significantly less postoperative morbidity (P 5 .001), and a weighted-average median cost savings of $1527 to $2939 per patient compared with patients who underwent open left lateral sectionectomy.

SURGICAL MARGINS

Initial concerns about the adequacy of surgical margins and possible tumor seeding prevented the widespread adoption of laparoscopic resection approaches for liver cancers. In comparison studies, there were no differences in margin-free resections between laparoscopic and open liver resection. In addition, no incidence of port-site recurrence or tumor seeding has been reported. With more than 3000 cases of minimally invasive hepatic resection reported in the literature (and no documentation of any significant port-site or peritoneal seeding), the authors conclude that this concern should not prevent surgeons from accepting a laparoscopic approach.

SURVIVAL OUTCOMES

There were no significant differences in overall survival in the 13 studies that compared laparoscopic liver resection with open liver resection for cancer. For example, Cai and colleagues showed that the 1-, 3-, and 5-year survival rates after laparoscopic resection of HCC were 95.4%, 67.5%, and 56.2% versus 100%, 73.8%, and 53.8% for open resection. For resection of colorectal cancer liver metastasis, Ito and colleagues showed a 3-year survival of 72% after laparoscopic liver resection and 56% after open liver resection whereas Castaing and colleagues51 showed a 5-year survival of 64% after laparoscopic liver resection versus 56% after open liver resection.

CONCLUSION

Compared with open liver resections, laparoscopic liver resections are associated with less blood loss, less pain medication requirement, and shorter length of hospital stay. A randomized controlled clinical trial is the best method to compare laparoscopic with open liver resection; however, such a trial may be difficult to conduct because patients are unlikely to subject themselves to an open procedure when a minimally invasive approach has been shown feasible and safe in experienced hands. In addition, many patients would have to be accrued to detect a difference in complications that occur infrequently. Short of a large randomized clinical trial, meta-analysis and matched comparisons provide the next best option to compare laparoscopic with open liver resection. For laparoscopic resection of HCC or colorectal cancer metastases, there has been no difference in 5-year overall survival compared with open hepatic resection. In addition, from a financial standpoint, the minimally invasive approach to liver resection may be associated with higher operating room costs; however, the total hospital costs were offset or improved due to the associated shorter length of hospital stay with the minimally invasive approach.

Medically-Necessary, Time Sensitive: (MeNTS) Score

Operating During The COVID-19 Coronavirus Pandemic

“At the University of Chicago, members of the Department of Surgery decided to investigate this issue more precisely. As stay-at-home restrictions in some states are easing, and as non-emergency medical care is being reconsidered, how does one possibly triage the thousands upon thousands of patients whose surgeries were postponed? Instead of the term “elective,” the University of Chicago’s Department of Surgery chose the phrase “Medically-Necessary, Time Sensitive” (MeNTS). This concept can be utilized to better assess the acuity and safety when determining which patients can get to the operating room in as high benefit/low risk manner as possible. And unlike in any recent time in history, risks to healthcare staff as well as risks to the patient from healthcare staff, are now thrown into the equation. The work was published in the April issue of the Journal of the American College of Surgeons.

On March 17, 2020, the American College of Surgeons recommended that all “elective” surgeries be canceled indefinitely. These guidelines were published, stating that only patients with “high acuity” surgical issues, which would include aggressive cancers and severely symptomatic disease, should proceed. Based on the Elective Surgery Acuity Scale (ESAS), most hospitals were strongly encouraged to cancel any surgery that was not high acuity, including slow-growing cancers, orthopedic and spine surgeries, airway surgeries, and any other surgeries for non-cancerous tumors. Heart surgeries for stable cardiac issues were also put on hold. Patients and surgeons waited. Some patients did, indeed undergo non-Covid-19-related surgeries. But most did not. Redeployment is gradually turning to re-entry.

The re-entry process for non-urgent (yet necessary) surgeries is a complicated one. Decisions and timing, based on a given hospital’s number and severity of Covid-19 patients, combined with a given city or state’s current and projected number of Covid-19 cases, how sick those patients will be, and whether or not a second surge may come, involves a fair amount of guesswork. As we have all seen, data manipulation has become a daily sparring match in many arenas. The authors of the study created an objective surgical risk scoring system, in order to help hospitals across this country, as well as others across the world, better identify appropriate timing regarding which surgeries can go ahead sooner rather than later, and why. They factored several variables into their equation, to account for the multiple potential barriers to care, including health and safety of hospital personnel. They created scoring systems based on three factors: Procedure, Disease and Patient Issues.

The authors of the study created an objective surgical risk scoring system, in order to help hospitals across this country, as well as others across the world, better identify appropriate timing regarding which surgeries can go ahead sooner rather than later, and why. They factored several variables into their equation, to account for the multiple potential barriers to care, including health and safety of hospital personnel.  Each patient would receive an overall conglomerate score, based on all of these factors, with the lower risks giving them more favorable scores to proceed with surgery soon, and the higher risks giving patients a higher score, or higher risk regarding proceeding with surgery, meaning it may be safest, for now, to wait.

Dr. Jeffrey Matthews, senior author of the paper, and Department Chair at the University of Chicago, stated that this model is reproducible across hospital systems, in urban, rural, and academic settings. And in the event of potential unpredictable surges of Covid-19 cases, the scoring system “helps prioritize cases not only from the procedure/disease standpoint but also from the pandemic standpoint with respect to available hospital resources such as PPE, blood, ICU beds, and [regular hospital] beds.”

The scoring system is extremely new, and the coming weeks will reveal how patients, surgeons and hospitals are faring as patients without life-and-death emergencies and/or Covid-19 complications gradually begin filling the operating rooms and hospital beds. In addition, and perhaps just as important, the study authors note that creating systems whereby healthcare resources, safety, and impact on outcomes need to be considered more carefully for each patient intervention, the larger impact of each intervention on public health will be better understood: not only for today’s pandemic, but also in future, as yet unknown, global events.”

Covid-19 and Digestive Surgery

The current world Covid-19 pandemic has been the most discussed topic in the media and scientific journals. Fear, uncertainty, and lack of knowledge about the disease may be the significant factors that justify such reality. It has been known that the disease presents with a rapidly spreading, it is significantly more severe among the elderly, and it has a substantial global socioeconomic impact. Besides the challenges associated with the unknown, there are other factors, such as the deluge of information. In this regard, the high number of scientific publications, encompassing in vitro, case studies, observational and randomized clinical studies, and even systematic reviews add up to the uncertainty. Such a situation is even worse when considering that most healthcare professionals lack adequate knowledge to critically appraise the scientific method, something that has been previously addressed by some authors. Therefore, it is of utmost importance that expert societies supported by data provided by the World Health Organization and the National Health Department take the lead in spreading trustworthy and reliable information.

Tratamento Cirúrgico do Abscesso Hepático Piogênico

Introdução

O abscesso hepático piogênico (AHP) é uma condição infecciosa grave caracterizada por uma coleção encapsulada de material purulento no fígado. Frequentemente, essa condição é resultante de infecções bacterianas, originárias do trato biliar ou de fontes intra-abdominais, como diverticulite. O manejo do AHP requer uma abordagem multidisciplinar, combinando diagnóstico rápido, antibioticoterapia e, em muitos casos, intervenção cirúrgica. No Brasil, a mortalidade associada a essa condição pode variar de 10% a 20%, sendo particularmente elevada em pacientes com comorbidades, como diabetes e cirrose. A presente revisão discute as abordagens cirúrgicas no tratamento do AHP, com ênfase nos critérios de intervenção, técnicas cirúrgicas e melhores práticas para o cirurgião do aparelho digestivo.

Diagnóstico e Classificação

O diagnóstico precoce do AHP é essencial para determinar a abordagem terapêutica mais adequada. Exames de imagem, como ultrassonografia (USG) e tomografia computadorizada (TC), são as ferramentas primárias para identificar a extensão da lesão e guiar a tomada de decisões. A classificação dos abscessos hepáticos baseia-se em seu tamanho e características morfológicas:

  • Abscessos pequenos (menores que 3 cm) podem, muitas vezes, ser tratados com antibioticoterapia isolada.
  • Abscessos maiores (geralmente >5 cm) e multiloculados exigem drenagem percutânea ou intervenção cirúrgica.

A etiologia do AHP no Brasil é predominantemente associada a bactérias como Escherichia coli e Klebsiella pneumoniae, e pacientes imunocomprometidos, como diabéticos, estão em maior risco de desenvolver complicações graves.

Abordagem Terapêutica

O tratamento do AHP é multimodal e deve ser adaptado à gravidade do caso, com o uso combinado de antibióticos, drenagem percutânea e intervenção cirúrgica, quando necessário. As diretrizes atuais propõem um algoritmo terapêutico baseado no tamanho e nas características dos abscessos.

1. Antibioticoterapia

A antibioticoterapia empírica deve ser iniciada imediatamente após o diagnóstico, visando cobertura para bactérias gram-negativas e anaeróbias. Ciprofloxacina ou cefixima combinadas com metronidazol são frequentemente utilizadas no manejo de abscessos hepáticos não complicados. A escolha do antibiótico deve ser ajustada conforme os resultados das culturas de sangue e de amostras do abscesso, garantindo uma abordagem personalizada.

2. Drenagem Percutânea

A drenagem percutânea, guiada por USG ou TC, é o tratamento de escolha para abscessos maiores que 3 cm e uniloculares (Tipo II). Esse método minimamente invasivo apresenta uma alta taxa de sucesso, próxima a 90%, sendo eficaz na maioria dos casos. No entanto, falhas podem ocorrer em abscessos multiloculados ou com conteúdo viscoso ou necrótico, situações em que a drenagem percutânea se torna inadequada, necessitando de intervenção cirúrgica.

3. Intervenção Cirúrgica

A cirurgia está indicada em abscessos multiloculados grandes (>3 cm, Tipo III), em abscessos que não respondem à drenagem percutânea ou na presença de complicações, como ruptura do abscesso. A cirurgia pode envolver drenagem minimamente invasiva ou ressecção hepática, dependendo da complexidade do abscesso e da experiência do cirurgião. Abscessos maiores que 10 cm apresentam maior risco de complicações, e nesses casos, a drenagem cirúrgica pode ser preferível. A laparotomia é recomendada em situações de peritonite ou quando o abscesso é de difícil acesso para drenagem percutânea.

4. Laparoscopia

A laparoscopia é uma alternativa minimamente invasiva à cirurgia aberta, indicada em abscessos uniloculares de tamanho moderado. Essa técnica oferece vantagens significativas, como menor tempo de internação e recuperação mais rápida, além de menor risco de complicações pós-operatórias.

Aplicação na Cirurgia Digestiva

O papel do cirurgião do aparelho digestivo é central no manejo dos abscessos hepáticos, especialmente em casos que requerem intervenção cirúrgica. A drenagem percutânea deve ser considerada a primeira linha de tratamento sempre que viável, mas o cirurgião deve estar preparado para realizar intervenções mais invasivas quando necessário. A laparoscopia tem demonstrado resultados promissores, reduzindo o tempo de internação e o risco de complicações. No Brasil, as infecções intra-abdominais complicadas são uma das principais causas de internação em emergências cirúrgicas, e o manejo adequado desses casos depende de uma sólida formação técnico-cirúrgica.

Algoritmo de Tratamento

Com base nas evidências disponíveis, um algoritmo de tratamento para o AHP pode ser delineado da seguinte forma:

  • Abscessos pequenos (<3 cm, Tipo I): Tratamento com antibióticos isolados.
  • Abscessos grandes uniloculares (>3 cm, Tipo II): Drenagem percutânea associada a antibioticoterapia.
  • Abscessos grandes multiloculados (>3 cm, Tipo III): Intervenção cirúrgica.

Pontos-Chave

  • Diagnóstico Precoce: O uso da TC com contraste é fundamental para o diagnóstico preciso do tamanho e da localização dos abscessos hepáticos, orientando a decisão terapêutica.
  • Intervenção Cirúrgica: Abscessos multiloculados ou maiores que 5 cm frequentemente requerem intervenção cirúrgica, especialmente quando a drenagem percutânea falha.
  • Abordagem Minimamente Invasiva: A laparoscopia oferece uma alternativa eficaz à cirurgia aberta, proporcionando uma recuperação mais rápida e com menor morbidade.
  • Manejo Integral pelo Cirurgião Digestivo: O conhecimento técnico-cirúrgico é essencial para o manejo de abscessos hepáticos complexos, garantindo uma abordagem eficaz e personalizada.

Conclusão

O manejo do abscesso hepático piogênico exige uma abordagem multidisciplinar, sendo o cirurgião digestivo uma peça-chave no tratamento de casos complexos. A decisão entre drenagem percutânea e intervenção cirúrgica deve considerar múltiplos fatores, como o tamanho do abscesso, a resposta ao tratamento conservador e as condições clínicas do paciente. Como afirmou o Prof. Henri Bismuth: “Le traitement chirurgical n’est pas seulement une question de technique, mais de jugement. Le moment de l’intervention est aussi important que l’intervention elle-même.” Assim, o domínio técnico e a tomada de decisões precisas são fundamentais para o sucesso terapêutico no tratamento do AHP.

Internal Hernia after Laparoscopic Gastric Bypass

The purpose of this review is to evaluate the incidence and management of internal hernias (with or without SBO) after LGBP.

INTRODUCTION

Laparoscopic Roux-en-Y gastric bypass (LGBP) has been shown to be an effective treatment for morbid obesity, both in terms of weight loss and improvement in multiple comorbidities. While the laparoscopic approach offers many advantages to the patient in terms of fewer wound complications, decreased length of hospital stay, and decreased postoperative pain, certain complications of this operation continue to pose difficult clinical problems as the number of procedures performed increases. One such complication is internal hernia through one of the mesenteric defects, which can result in small bowel obstruction, ischemia, or infarction and often requires reoperation.

An internal hernia is defined as a protrusion of intestine through a defect within the peritoneal cavity, as opposed to an external (or incisional) hernia that protrudes through all layers of the abdominal wall. Internal hernias almost always occur through iatrogenic defects created surgically.

Internal_Hernia_Ozimo_Gama

Incisional hernias occur at a higher incidence after open gastric bypass (GBP) at a rate of about 20 percent. LGBP has a lower rate of incisional hernias. A recent study by Rosenthal, et al., showed a 0.2-percent rate of port site hernias in 849 patients using blunt-tip trocars at 3,744 port sites. Internal hernias, on the other hand, occur more frequently in LGBP than in the open procedure. This is a significant clinical problem, since internal hernia is the most common cause of small bowel obstruction (SBO) after LGBP. Retrospective reviews have found the incidence of SBO after LGBP to be between 1.8 and 9.7 percent. The incidence of internal hernia after LGBP is between 0.2 and 8.6 percent based on multiple studies.

This incidence is higher than that seen with open GBP, and this is presumably due to decreased adhesion formation after laparoscopic surgery compared to open surgery. The creation of potential space as a result of weight loss may also be a contributing factor in the etiology of internal hernias, which often present in a delayed fashion. In addition, the particular case of pregnancy— with the mass effect of an enlarging uterus—may predispose to this condition, as there have been three case reports in the literature of internal hernia during pregnancy, one of which resulted in intestinal ischemia and fetal demise. Due to the increasing scope of this problem and its potentially devastating consequences, surgeons should have a high clinical suspicion for internal hernia after LGBP.

An internal hernia can potentially occur through either two or three defects, depending on whether a retrocolic or antecolic technique is used for the Roux limb. Petersen’s defect is defined as the space between the Roux limb and the transverse mesocolon. A defect is also present between the biliopancreatic and Roux limbs at the jejunojejunostomy. If a retrocolic approach is used, a third defect in the transverse mesocolon is created. This is the most common site of internal hernia in most reports, which has prompted many surgeons to adopt an antecolic technique in order to eliminate this defect. Higa’s study of 2,000 patients showed an internal hernia distribution of 67 percent mesocolic, 21 percent jejunal, and 7.5 percent Petersen. However, some centers experience a higher rate of hernia in the jejunal or Petersen’s defects, despite the use of a retrocolic approach.

PRESENTATION

Patients with internal hernia most commonly present with abdominal pain, and may also have symptoms of small bowel obstruction. The time of presentation varies greatly and may occur within one week of the initial operation or up to three years postoperatively. However, the majority of cases occur between 6 and 24 months postoperative. Radiographic diagnosis of internal hernia presents a challenge since the characteristic findings on computed tomography (CT) scan are often missed.

Features suggestive of an internal hernia include small bowel loops in the upper quadrants; evidence of small bowel mesentery crossing the transverse mesocolon; presence of the jejunojejunostomy superior to the transverse colon; signs of small bowel obstruction; or twisting, swirling, crowding, stretching, or engorgement of the main mesenteric trunk and according to one study, the sensitivity and specificity of CT is 63 percent and 76 percent, respectively.

Another study showed that although the diagnosis was only made prospectively by CT scan in 64 percent of cases, a retrospective review of the images showed that diagnostic abnormalities were present in 97 percent of cases. A report of five cases of internal hernia by Onopchenko found that only one was diagnosed preoperatively by radiological reading, even though all five had findings suggestive of internal hernia to the bariatric surgeon. These findings emphasize the need for communication with the radiologist, careful attention to patient history, and high clinical suspicion for internal hernias. In rare cases, closed loop obstruction and extensive bowel ischemia and infarction can occur. This dreaded complication underscores the necessity of making a rapid diagnosis. If the patient has significant symptoms but radiologic studies are negative, a diagnostic laparoscopy is warranted to rule out internal hernia.

PREVENTION AND TREATMENT

Given the prevalence of internal hernias and the increasing popularity of bariatric surgery, it is important to prevent or minimize this complication at the time of the initial operation. Although there have been no randomized, controlled trials comparing different techniques of LGBP, some authors have anecdotally reported lower rates of internal hernia after modifying their technique from a retrocolic to antecolic approach. Champion and Williams reported a significant decrease in small bowel obstruction after changing to an antecolic position, and Felsher and colleagues found no internal hernias in their study after adopting the antecolic approach.

However, other studies support careful defect closure as the most important factor in reducing hernia rates. Dresel and colleagues report no internal hernias after modifying their technique to include closure of Petersen’s defect. Carmody and colleagues report a decreased hernia incidence when closing all defects, even with a retrocolic approach. DeMaria’s study reports anecdotal improvement after closing mesenteric defects in two layers, on the medial and lateral aspects of the defect.

The majority of internal hernias can be successfully treated laparoscopically, with reduction and defect closure. The laparoscopic approach is usually successful; however, because of the lack of adhesion formation after laparoscopy, Capella, et al., suggest laparotomy for patients who experience a second episode of bowel obstruction due to recurrent internal hernia after laparoscopic repair. The greater adhesion formation after laparotomy may help prevent future internal hernia formation.

CONCLUSION

One of the benefits of laparoscopy, decreased adhesion formation, is likely also responsible for the increasing prevalence of internal hernia as a complication following laparoscopic gastric bypass. Although it has not been borne out in randomized clinical trials, anecdotal evidence and expert opinion suggest that Roux limb position and mesenteric defect closure at the time of initial operation are important factors in ultimate rates of hernia formation. Careful attention must be paid to individual surgical techniques in order to prevent this potentially devastating complication. The benefits of LGBP are maximized when there is a low incidence of postoperative hernias and resultant obstruction.

Anatomia Cirúrgica Pancreática

A anatomia cirúrgica do pâncreas é um dos tópicos mais fascinantes e desafiadores da cirurgia do aparelho digestivo. Conhecer detalhadamente a estrutura e a topografia do pâncreas é crucial para a realização de procedimentos cirúrgicos seguros e eficazes. Neste artigo, vamos explorar os aspectos mais importantes da anatomia pancreática, abordando pontos-chave para estudantes de medicina e residentes de cirurgia do aparelho digestivo.

Estrutura Anatômica do Pâncreas

O pâncreas é uma glândula retroperitoneal situada transversalmente no abdome, na altura das vértebras L1-L2, abrangendo os principais vasos sanguíneos e a coluna vertebral. Ele é composto por cinco partes principais: cabeça, colo, corpo, cauda e processo uncinado.

  • Cabeça: Localizada à direita da linha média, cercada pelo duodeno. A cabeça do pâncreas possui uma extensão inferior chamada processo uncinado, que está intimamente relacionada com a veia mesentérica superior e a artéria mesentérica superior.
  • Colo: Uma parte estreita entre a cabeça e o corpo, situada anteriormente à veia porta, definida pela localização anatômica anterior à formação da veia porta, geralmente pela confluência das veias mesentérica superior e esplênica.
  • Corpo: Estende-se para a esquerda, posterior ao estômago, com a superfície anterior coberta pelo peritônio, formando parte da parede posterior do saco menor.
  • Cauda: Parte terminal que se estende até o hilo esplênico, confinada entre as camadas do ligamento esplenorrenal juntamente com a artéria esplênica e a origem da veia esplênica.
  • Processo Uncinado: Considerado uma parte distinta do pâncreas devido à sua origem embriológica diferente, estendendo-se posteriormente aos vasos mesentéricos superiores.

Peso e Dimensões Normais

Em um adulto saudável, o pâncreas tem um peso médio de aproximadamente 80 a 120 gramas. As dimensões normais do pâncreas variam, mas geralmente medem cerca de 15 a 20 cm de comprimento, 4 a 5 cm de largura na cabeça, e 1,5 a 2,5 cm de espessura.

Vascularização do Pâncreas

A vascularização do pâncreas é complexa e vital para a compreensão cirúrgica. As principais artérias que irrigam o pâncreas são:

  • Artéria Pancreatoduodenal Superior: Ramo da artéria gastroduodenal que irriga a cabeça do pâncreas.
  • Artéria Pancreatoduodenal Inferior: Ramo da artéria mesentérica superior que também fornece sangue à cabeça do pâncreas.
  • Ramos Pancreáticos da Artéria Esplênica: Irrigam o corpo e a cauda do pâncreas.

As veias pancreáticas drenam para a veia esplênica, veia mesentérica superior e, eventualmente, para a veia porta.

Ductos Pancreáticos

O pâncreas possui dois principais ductos: o ducto pancreático principal (ducto de Wirsung) e o ducto pancreático acessório (ducto de Santorini).

  • Ducto Pancreático Principal (Ducto de Wirsung): Começa na cauda do pâncreas e percorre o corpo até a cabeça, onde geralmente se junta ao ducto biliar comum na ampola de Vater, regulada pelo esfíncter de Oddi. O diâmetro normal do ducto pancreático principal varia de 1 mm na cauda até 3 mm na cabeça.
  • Ducto Pancreático Acessório (Ducto de Santorini): Corre superior e paralelo ao ducto de Wirsung, drenando parte da cabeça do pâncreas na papila duodenal menor.

O esfíncter de Oddi é uma estrutura única de fibras musculares lisas que regula o fluxo das secreções biliares e pancreáticas para o duodeno e impede o refluxo do conteúdo intestinal para o sistema ductal pancreatobiliar.

 

Considerações Cirúrgicas

Entender a anatomia pancreática é essencial para evitar complicações durante procedimentos cirúrgicos. Algumas das considerações importantes incluem:

  • Ressecção Pancreática: Procedimentos como a pancreatoduodenectomia (procedimento de Whipple) requerem um conhecimento detalhado das relações anatômicas para garantir a remoção eficaz do tumor com a menor morbidade possível.
  • Drenagem Biliar: A proximidade do pâncreas com o ducto biliar comum exige precisão ao evitar danos durante as cirurgias.
  • Anastomoses Pancreáticas: A criação de anastomoses seguras entre o pâncreas e o intestino é crítica para prevenir complicações pós-operatórias, como fístulas pancreáticas.

Variações Anatômicas

As variações anatômicas do pâncreas e dos ductos pancreáticos são comuns e podem impactar significativamente a abordagem cirúrgica. Uma compreensão detalhada dessas variações é essencial para a personalização do plano cirúrgico. Por exemplo, o pâncreas anular é uma condição em que o tecido pancreático forma um anel ao redor do duodeno, podendo causar estenose duodenal.

Conclusão

A anatomia cirúrgica pancreática é um campo complexo e detalhado que exige estudo e prática contínuos. Compreender as nuances dessa anatomia é fundamental para qualquer cirurgião do aparelho digestivo. Como disse o renomado anatomista Andreas Vesalius: “A anatomia é a fundação de todas as ciências médicas.”

Nutritional Management of Acute Pancreatitis

Acute pancreatitis is a common intra-abdominal inflammatory condition of varied aetiology. The disease is mild in the vast majority of patients and has a favourable outcome. The acute severe form of the disease on the other hand is a lethal form with a high mortality and morbidity. A number of strategies have provided clinical benefit in severe acute pancreatitis (SAP). Of these, nutritional management is by far the most effective. SAP is associated with persistent end-organ failure, commonly respiratory, circulatory and renal. Treatment is targeted to support these organs. As of now there is no definitive therapy for acute pancreatitis. Patients are managed with fluids, analgesics, antibiotics and nutritional supplements besides adequately treating local complications such as pseudocyst and walled-off pancreatic necrosis by suitable interventional methods, be it endoscopic or percutaneous. The focus here is nutritional support in the management of SAP.

Which Form of Nutrition: Parenteral or Enteral?

This depends largely on the functional integrity of the stomach and small intestine. Patients of SAP often have poor gastric emptying and paralytic ileus, which is made worse with the use of narcotics. Moreover, local complications of pancreatitis (peripancreatic fluid collections) can have a pressure effect on the stomach and/or duodenum. As a result oral feeds may not be possible in these patients. Patients on ventilator support also cannot be given oral feeds.

Enteral feeding through the nasogastric or nasojejunal tubes is often not tolerated by patients because of discomfort. In addition, these tubes often get displaced or withdrawn. Reinsertion of the tubes, under endoscopic or radiological guidance, is cumbersome in such patients. All these factors favour parenteral feeding. The distinct advantage of enteral nutrition is that it prevents mucosal atrophy and transmigration of bacteria (an important causeof sepsis in SAP). Also, enteral feeding augments intestinal motility and is cheaper than parenteral preparations. Enteral nutrition improves motility in patients with paralytic ileus. The relative merits of these forms of nutritional therapy have been evaluated in a systematic review. Eight published randomized trials including a total of 348 patients were included. Enteral feeding was given through a nasojejunal tube and parenteral nutrition through a catheter placed in a central vein. Enteral nutrition was shown to reduce mortality, multi-organ failure, systemic infection and surgical intervention in comparison with parenteral nutrition. The length of hospital stay too was shown to be reduced. In view of these, enteral nutrition appears to be a better option while managing patients of SAP and has been recommended by the American College of Gastroenterology, American Gastroenterological Association and International Association of Pancreatology.

When should enteral feeding be started?

Patients with mild acute pancreatitis can usually be started on oral feeds in 2–3 days. Those with moderately severe acute pancreatitis can be started on oral feeding only after a variable period and hence should receive enteral nutritional support. Early enteral feeding has been shown to avoid end-organ failure in a large series of patients (1200).

Enteral feeding started within 48 h of onset of illness was associated with organ failure in 21% of patients as opposed to 81% when enteral feeding was started after 48 h. This benefit of early enteral feeding has also been shown in a recent meta-analysis. However, there was no benefit in mortality with early enteral feeding. In yet another randomized controlled trial, early enteral feeding (within 24 h) was compared with on-demand enteral feeding after 72 h.

The primary endpoint of this study was major infection or death. The study did not detect any significant difference in the primary endpoint in either group (early or on-demand feeding). However, it did show that patients receiving on-demand nutrition tolerated oral feeds without using a tube.

  • Nasogastric or Nasojejunal

Should the feed be administered in the stomach through a nasogastric (NG) tube or in the jejunum through a nasojejunal (NJ) tube? Gastric feeding is thought to increase pain and aggravate pancreatitis due to food-induced pancreatic stimulation. In view of this, NJ feeding is practised. However, placement of a NJ tube is cumbersome and needs a skilled endoscopist or radiologist. It causes more inconvenience to patients. A nasogastric (NG) tube is thus an alternative. A number of studies have been published comparing NG and NJ feeding. The results of these studies can be summarized as follows: There was no difference in mortality. Feeds were equally tolerated in the two groups and NG feeding is simple. NG feed was not shown to increase pain and is thus as good as NJ feeding. A meta-analysis subsequently published showed no difference in mortality, hospital stay and infection rate between the two groups. Both forms of feeding were equally well tolerated. NJ feeding thus is not advised in the management of most patients with SAP. However, it still has a place when the patient has a high risk of aspiration. Also, patients on a ventilator and those not tolerating NG feed should be fed through NJ tube. The other issue concerning enteral feeding in SAP is the composition of the feed.

  • Type of Formulation

Various commercially available formulations include (1) polymeric formulations comprising complex lipids, carbohydrates and proteins and (2) elemental formulations comprising simple amino acids, carbohydrates and free fatty acids. Other formulations used are glutamine-rich feeds and feeds with probiotics, fibres, etc. Immuno-nutrition using arginine, glutamine and polyunsaturated fatty acids has been evaluated in multiple studies and compared with standard feeding. A metaanalysis showed some benefit in mortality but not for prevention of infection, end-organ failure or inflammatory response. This benefit was not seen with the use of probiotics or fibre-based feeds. A systematic review did not show any benefit of immuno-nutrition or probiotics. It also showed that polymeric formulations are as well tolerated as oligomeric ones (elemental).

ERCP Induced Perforations

In the epoch of minimally invasive management of biliary and pancreatic disorders, endoscopic retrograde cholangiopancreatography (ERCP) combined with endoscopic sphincterotomy (ES) has become a prevalent procedure all over the world. Even though ES is a safe procedure, it carries a small but significant number of serious complications which include pancreatitis, bleeding, cholangitis and perforation. As per old literature, ERCP-related perforations were reported in 0.5–2.1% of sphincterotomies with a mortality rate of 16–18%. However, the improvement in the experience and skill of the endoscopy specialists combined with advancements in technology have reduced the incidence of perforation to <0.5% over the years. Sphincterotomy (56%) and guidewire manipulation (23%) are widespread causes of perforations related to endoscopic retrograde cholangiopancreatography (ERCP). There is a dearth of evidence-based strategies with respect to the proper management of ERCP perforations. While one set of investigators promote on-demand conservative and surgical management, based on a clinical course, the others support operative repair in all cases on account of the complications associated with the delayed operative intervention.

INDICATIONS OF SURGICAL MANAGEMENT

1. Large extravasation of contrast at the time of ERCP defined as incomplete dissipation of contrast after 1 min on follow-up plain film.
2. If there is only a small amount of contrast extravasation, where there is complete dissipation after 1 min of ERCP, on follow-up plain film, then a UGI with contrast injection on fluoroscopy is performed in 2–8 h. If this shows extravasation, we recommend surgical exploration.

3. Follow-up CT scan showing a collection due to perforation in the retroperitoneum or intraperitoneum.
4. Retained hardware unable to be removed by endoscopy along with perforation.
5. Massive subcutaneous emphysema.
6. Failure of conservative management.

A delay in diagnosis or in surgery will lead to death. The reason is that there is a massive autodigestion of body tissues which is due to a constant release of enzymes, and this eventually leads to sepsis. The principle of treatment by surgery is the same as endoscopic treatment. Any case that is suspected to have ERCP-induced perforation is kept nil by mouth, and the gastric contents are decompressed by Ryles tube and intravenous antibiotics.

This is done by diverting bile, enteric and pancreatic juices away from the site of perforation. However simple drainage will also cause the juices to flow through the perforation site and body cavities before draining out of the tubes. This could be avoided by diverting the juices through well-controlled different paths which could be done by the following procedures:
1. T-tube in CBD;
2. Placement of duodenostomy tube—lateral/end duodenostomy;
3. Duodenal diverticulization;
4. Pyloric exclusion;
5. Roux-en-Y duodenojejunostomy.

The disadvantage of using Roux-en-Y duodenojejunostomy is that if the edges are inflamed, then the sutures will not hold properly. However other procedures can be used even when the edges are inflamed. Even though duodenostomy appears to be simple, a part of gastric and duodenal contents pass across the perforation site.

Duodenal diverticulization involves three things: (1) tube to divert duodenal and pancreatic juice, (2) T-tube in CBD to divert bile and (3) distal
gastrectomy and Billroth II anastomosis to provide an alternate pathway for food and gastric juice, thereby preventing these from passing through the site of perforation. Although this procedure has been proved to be successful, it is less widely used due to its complex nature. Pyloric exclusion is a simpler form in which the pylorus is closed by purse string by long-standing absorbing sutures like PDS 2.0 instead of distal gastrectomy. Similar to duodenal diverticulization, T-tube drainage of the CBD and loop gastrojejunostomy are done. The duodenal perforation is closed over a duodenostomy tube.

Whenever there is collection which is localized to the retroperitoneum, retroperitoneal surgical approach can be carried out. Advantages of this procedure are (1) it permits gravitational drainage, (2) avoids septic complication of the peritoneal cavity, (3) directs retroperitoneal necrosectomy with post-operative washes and (4) avoids complex intra-abdominal surgeries. However the disadvantage of this procedure is that it can be used only for retroperitoneal-contained perforations.
