Coronavirus disease 2019 (COVID-19) emerged in Wuhan City and rapidly spread throughout China and around the world since December 2019. The World Health Organization (WHO) declared the COVID-19 outbreak a global pandemic on 11 March 2020. Patients with metabolic disorders like cardiovascular diseases, diabetes and obesity may face a greater risk of infection of COVID-19 and it can also greatly affect the development and prognosis of pneumonia.
“A higher cumulative MeNTS score, which can range from 21 to 105, is associated with poorer perioperative patient outcome, increased risk of COVID-19 transmission to the health care team, and/or increased hospital resource utilization. Given the need to maintain OR capacity for trauma, emergency, and highly urgent cases, an upper threshold MeNTS score can be designated by surgical and perioperative leadership based on the immediately anticipated conditions and resources at each institution.”
All elective surgical and endoscopic cases for metabolic and bariatric surgery should be postponed during the pandemic. This minimises risks to both patient and healthcare team, as well as reducing the utilisation of unnecessary resources, such as beds, ventilators and personal protective equipment (PPE). In addition, postponing these services will minimise potential exposure of the COVID-19 virus to unsuspecting healthcare providers and patients. As the long-term effects or complications of COVID-19 are still unknown, metabolic and bariatric surgeries for patients who were diagnosed and recovered from COVID-19 should be evaluated by a multidisciplinary team. Diet and lifestyle modifications should be advised before surgical treatment.

Many oncological patients with upper gastrointestinal (GI) tract tumours, apart from other symptoms, are malnourished or cachectic at the time of presentation. In these patients feeding plays a crucial role, including as part of palliative treatment. Many studies have proved the benefits of enteral feeding over parenteral if feasible. Depending on the tumour’s location and clinical stage there are several options of enteral feeding aids available. Since the introduction of percutaneous endoscopic gastrostomy (PEG) and its relatively easy application in most patients, older techniques such as open gastrostomy or jejunostomy have rather few indications.
The majority of non-PEG techniques are used in patients with upper digestive tract, head and neck tumours or trauma that renders the PEG technique unfeasible or unsafe for the patient. In these patients, especially with advanced disease requiring neoadjuvant chemotherapy or palliative treatment, open gastrostomy and jejunostomy were the only options of enteral access. Since the first report of laparoscopic jejunostomy by O’Regan et al. in 1990 there have been several publications presenting techniques and outcomes of laparoscopic feeding jejunostomy. Laparoscopic jejunostomy can accompany staging or diagnostic laparoscopy for upper GI malignancy when the disease appears advanced, hence avoiding additional anaesthesia and an operation in the near future.
In this video the author describe the technique of laparoscopic feeding jejunostomy applied during the staging laparoscopy in patient with advanced upper gastrointestinal tract cancer with co-morbid cachexy, requiring enteral feeding and neoadjuvant chemotherapy.

Basicamente, existem quatro situações que indicam a realização de traqueostomia: prevenção de lesões laringotraqueais pela intubação translaríngea prolongada; desobstrução da via aérea superior, em casos de tumores, corpo estranho ou infecção; acesso à via aérea inferior para aspiração e remoção de secreções; e aquisição de via aérea estável em paciente que necessita de suporte ventilatório prolongado.
A substituição do tubo endotraqueal pela cânula de traqueostomia ainda acrescenta benefícios, proporcionando conforto e segurança do paciente. Algumas sociedades americanas sugerem que a traqueostomia deva ser sempre considerada para pacientes que necessitarão de ventilação mecânica prolongada, ou seja, por mais de 14 dias.
Muitas vezes, a decisão de se realizar uma traqueostomia é tomada pelo julgamento clínico de médicos, principalmente aqueles que trabalham em unidades de terapia intensiva. Isso envolve a análise de múltiplos fatores, tais como as características de cada paciente, o motivo pelo qual ocorreu a intubação, doenças associadas, resposta ao trata-mento e prognóstico individualizado. Embora haja uma tendência de indicação de traqueostomia precoce em pacientes neurocríticos e com trauma grave.
- Diminuição do trabalho respiratório
- Melhora da aspiração das vias aéreas
- Permitir a fonação
- Permitir a alimentação por via oral
- Menor necessidade de sedação
- Redução do risco de pneumonia associada à ventilação
- Diminuição do tempo de ventilação mecânica
- Diminuição do tempo de internação em unidades de terapia
- Redução da mortalidade
Pyogenic liver abscess (PLA), a suppurating infection of the hepatic parenchyma, remains a mortality associated condition and nowadays develops as a complication of biliary tract diseases for about 40% of cases. Recently, the etiologies of PLA have shifted from intra-abdominal infections such as acute appendicitis and trauma to pathologic conditions of the biliary tract; however, up to 60% of patients with PLA have no clear risk factors and these cases are called cryptogenic.
The incidence of PLA varies from 8 to 22 patients per 1,000,000 people belonging to a geographical area with substantially higher rates having been reported in Taiwan. Early diagnosis and treatment is a crucial step in the management of these patients, since the presentation may be subtle and not specific (abdominal pain, fever, nausea, and vomiting), so currently constitutes a challenge for physicians: a high index of suspicion is the cornerstone of prevention for misdiagnosis and improvement of prognosis.
In recent decades, combined antibiotic therapy and percutaneous drainage have become the first-line treatment in most cases and has greatly improved patients’ prognosis: the mortality rate has dropped from 70% to 5%. In terms of causative pathogens, bacteria most frequently associated with PLA are Escherichia coli, Enterobacteriaceae, anaerobes, and other members of the gastrointestinal flora. Over the past 2 decades Klebsiella pneumoniae has been emerging as the predominant pathogen responsible for 50% to 90% of PLA in the Asian population and it has been reported with increasing frequency in South Africa, Europe, and the United States.
Because such experiences have not yet been reported in Maranhão, we reviewed the cases of PLA seen at our institution and the present study is a retrospective analysis of demographic characteristics, etiological factors, presentation patterns, microbiological etiology, and the treatment of PLA cases which were presented in an Brazilian hospital over a 25-year-period.
