Surgical Management of GERD After Sleeve Gastrectomy

Evaluation of a patient referring GERD after sleeve gastrectomy should start with a detailed history and physical examination; the presence or absence of GERD-related symptoms should be thoroughly documented as well as any prior treatments or therapy used to treat it. Obtaining preoperative and operative records is of paramount importance particularly in those patients who had their index procedure performed elsewhere. Any endoscopic findings and prior imaging available are important to determine what the best course of action would be. If the patient had preoperative and postoperative imaging such as UGI, it is useful to compare those with a recent study to look for anatomical problems that may have been not addressed at the time of the index operation or developed over time. After this information is obtained, we can classify the GERD after sleeve as:


1. De novo GERD
2. Preexisting GERD without improvement
3. Preexisting GERD with worsening/complication


Regardless of how we classify the GERD, an initial evaluation with imaging
studies such as UGI and EGD is recommended. Comparison with any prior films if available is of significant value. Based on the UGI, we can determine if the shape of the sleeve falls into one of the following categories: tubular, dilated bottom, dilated upper, or dumbbell-shaped sleeve; we will also be able to evaluate esophageal peristalsis in real time and if there is associated hiatal hernias. We believe UGI under fluoroscopy provides important physiologic and anatomic information that can help guide our management approach, and therefore we offer it to all patients. We follow the radiologic evaluation with endoscopy, and during endoscopy, we look for objective signs of reflux such as esophagitis, presence of bile in the stomach or esophagus, as well as missed or recurrent hiatal hernias. In patients with evidence of esophagitis or metaplasia, multiple biopsies are taken. During the endoscopy, subtle findings that suggest a kink or a stricture may be present. In the absence of objective signs of gastroesophageal reflux disease on both endoscopy and upper GI series, we pursue physiologic testing followed by highresolution manometry and pH monitoring. In those patients where clear reflux esophagitis is seen, this additional testing may not be necessary or may be performed in selected cases depending on what the surgical or endoscopic therapy would be.

GERD AFTER SLEEVE GASTRECTOMY

While it is true that most sleeve-related GERD will be effectively treated with a conversion to Roux-en-Y gastric bypass, not every patient with GERD after reflux will require a bypass or would agree to have one. First key step in addressing the patient is to evaluate whether the patient was selected appropriately to have a sleeve and second is to determine the exact sleeve anatomy; are there anatomical factors that will make it more likely for this patient to experience reflux; is there dilated fundus? Is there a kink or stricture in the sleeve or is it an anatomically appropriate operation? We should pay important attention to the weight loss the patient has experienced with the sleeve. Patients who do not have adequate weight loss and have GERD symptoms should not undergo other therapies and should probably undergo a bypass; however it is our unpublished experience that patients with the association of poor weight loss after sleeve and difficult to treat GERD will correct their GERD after conversion, but their weight loss results are still marginal even with a well-constructed bypass.

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.

Bariatric Surgery During the COVID-19 Pandemic

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.

MENTS_SCORE_2020

“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.”

GENERAL RECOMMENDATIONS

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.

Laparoscopic JEJUNOSTOMY

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.

Pyogenic Liver ABSCESS

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 coliEnterobacteriaceae, 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.

Surgical Management of CHRONIC PANCREATITIS

Chronic_Pancreatitis

Chronic pancreatitis (CP) is a progressive, destructive, inflammatory process that ends in total destruction of the pâncreas and results in malabsorption, diabetes mellitus, and severe pain. The incidence and prevalence of CP are increasing in the worldwide and incidence is between 1.6 and 23 per 100 000 with increasing prevalence. The treatment of CP is complex; in the majority of cases na interdisciplinary approach is indicated that includes conservative, endoscopic, and surgical therapy. The surgical treatment of CP is based on two main concepts:preservation of tissue via drainage aims to protect against further loss of pancreatic function, and pancreatic resection is performed for nondilated pancreatic ducts, pancreatic head enlargement,or if a pancreatic carcinoma is suspected in the setting of CP.

RESECTIVE PROCEDURES

The vast majority of patients are seen with a ductal obstruction in the pancreatic head, frequently associated with an inflammatory mass. In these patients, pancreatic head resection is the procedure of choice; The partial pancreatoduodenectomy (PD) or Kausch-Whipple procedure, in its classic or pylorus-preserving variant, has been the procedure of choice for pancreatic head resection in CP for many years (Jimenez et al, 2003). The duodenum-preserving pancreatic head resections and its variants—the Beger (1985), Frey (1987), and Bern procedures (Gloor et al, 2001)—represent less invasive, organsparing techniques with equal long-term results. Only very few patients come to medical attention with smallduct disease (diameter of the pancreatic duct ❤ mm) and no mass in the pancreatic head. Possibly, a large majority of those patients from former series had unknown autoimmune pancreatitis. In these cases, a V-shaped excision of the anterior aspect of the pancreas is a safe approach, with effective pain management (Yekebas et al, 2006). In the rare case of a patient seen with segmental CP in the pancreatic body or tail, such as that seen as a result of posttraumatic ductal stenosis, a middle segment pancreatectomy or a pancreatic left resection may be the best approach.

CONCLUSION

The adequate therapy of CP is adjusted to the symptoms of the patient, the stage of the disease, and the morphology of pathologic changes of the pancreas. The surgical technique must be adjusted to the pathomorphologic changes of the pancreas. For patients with CP and an inflammatory mass in the head of the pancreas, the DPPHR is less invasive than a PD and is associated with comparable long-term results. The Bern modification of the DPPHR represents a technical variation that is equally effective but technically less demanding. Whether total pancreatectomy with islet cell transplantation is a viable therapy of CP remains to be proved by further studies. Surgical therapy provides effective long-term pain relief and improvement of quality of life, but it may not stop the decline of endocrine or exocrine pancreatic function. Strategies to improve or maintain endocrine and exocrine function in CP remain an interesting field of research.

Laparoscopic distal PANCREATECTOMY

Laparoscopic distal pancreatectomy has become a relatively standard operation and has been approached by a similar technique by multiple groups since its original description. Generally, four or five trocars are used to gain entrance to the abdominal cavity, but three-trocar LPD has been described. A “clockwise” technique results in an efficient, reliable, and uniform approach for removing the vast majority of lesions that are located to the left of the neck of the pancreas (Asbun & Stauffer, 2011). The technique begins with the positioning of the patient in a modified right lateral decubitus position. The degree of lateral positioning depends on the patient’s body habitus and the location of the lesion, as well as the tilting capabilities of the operative bed. The use of gravity assisted retraction with the patient in a reverse Trendelenburg position with the left flank elevated is a key component to successful exposure of the tail of the pancreas and the spleen. Four mid- to left-sided abdominal trocars are placed in a semicircle around the body and tail of the pancreas, including two 12 mm and two 5 mm trocars, and a five step clockwise method is used.

Step 1: Mobilization of the splenic flexure of the colon
and exposure of the pancreas

The first step is mobilization of the splenic flexure of the colon. The lateral attachments, splenocolic ligament, and gastrocolic ligament are succes-sively transected to allow access to the lesser sac. If the spleen is to be removed, the dissection proceeds cranially, and the short gastric vessels are transected up to the superior pole of the spleen. Sufficient mobilization of the colon allows for gravity-assisted retraction of the colon, and the stomach is completely freed from the anterior aspect of the body and tail of the pancreas. Infrequently, an additional trocar or tacking stitch is required to elevate the stomach to the anterior abdominal wall off the pancreas and out of the operative field.

Step 2: Dissection along the inferior edge of the pancreas
and choosing the site for pancreatic division

The second step is to identify the inferior border of the pancreas and create a window in the fibroadipose tissue plane between the retroperitoneum and the pancreas. This dissection is carried medially toward the lesion of interest. Intraoperative ultrasound is performed to clearly identify the lesion and the planned site of division of the pancreas.

Step 3: Pancreatic parenchymal division and ligation
of the splenic vein and artery

The third step is pancreatic parenchymal division and ligation of the splenic artery and vein. After dissecting around the pancreas in 360 degrees, a Penrose drain or suture is placed around the proposed site of division of the pancreas and is used to elevate the pancreas from the retroperitoneum. A band passer instrument is helpful for this part of the procedure. For distal pancreatectomy, the splenic vessels will often be dissected, ligated, and divided en bloc with the parenchyma. For subtotal resections with division of the pancreas at the neck, the underlying superior mesenteric vein and splenic vein are dissected away from the posterior aspect of the pancreas, and the celiac trunk is identified individually and dissected free from the neck and proximal body of the pancreas. Parenchymal transection is performed with a linear stapling device by using a slow, gradual, and stepwise compression technique. Thick tissue staples (open staple height of approximately 4 mm) with staple line reinforcement is preferred for almost any pancreas consistency, and the stapler is gradually closed in a stepwise manner over the course of several minutes to allow for parenchymal compression. Parenchymal transection and splenic vessel division are done individually for subtotal pancreatectomy for lesions located between the gastroduodenal artery and the celiac trunk.

Step 4: Dissection along the superior edge of the pancreas

The fourth step is to sweep the pancreas inferiorly and anteriorly off the retroperitoneum toward the splenic hilum. A deeper dissection plane that includes Gerota fascia and the left adrenal gland may be chosen for malig-nancies that appear to have posterior invasion from the pancreas.

Step 5: Mobilization of the spleen and specimen removal

The fifth step is the mobilization of the spleen from its diaphragmatic and retroperitoneal attachments and placement of the specimen within a bag for exteriorization. Major complications were seen in less than 10% of patients, and both the conversion rate and the clinically significant pancreatic fistula (grade B/C) rate by using the gradual stepwise compression stapled technique was seen in fewer than 5%. Operative drains were rarely placed.

Outcomes
The minimally invasive approach to resection of the left-sided pancreas by distal or subtotal pancreatectomy has gained acceptance and been used with an increasing frequency worldwide during the past decade. Multiple systematic reviews have demonstrated the safety of LDP and its superiority versus open distal pancreatectomy (ODP) for selected outcomes, such as blood loss, transfusion rates, and hospital stays; it must be remembered, however, that all these studies are retrospective in nature and therefore severely limited by significant selection bias. All studies showed similar reoperation rates and mortality, but most found a lower overall morbidity for the laparoscopic approach. Some studies identified lower rates of specific complications, such as wound infection and even pancreatic fistula. Although oncologic clearance was similar, most studies have shown that ODP is often the surgery of choice for larger tumors.

Hepatic Hemangioma: Is There an Indication for Surgical Resection?

Hepatic hemangioma (HH) is the most common benign liver tumor. It consists of blood-filled cavities fed by the hepatic arterial circulation, with walls lined by a single layer of endothelial cells, a veritable chaotic entanglement of distorted blood vessels confined to a region as small as a few mm and as large as 10 cm, 20 cm and even 40 cm. The frequency is higher among adults, with a prevalent age at the initial diagnostic in the range of 30-50 years. Literature places the HH incidence at 0.4% to 20% of the total population. At necropsy, the frequency is of 0.4 to 7.3%, all the authors agreeing with an incidence of over 7%. The HH prevalence in the general population varies greatly, most often being discovered incidentally during imaging investigations for various unrelated pathologies. Regarding sex distribution, it seems that women are more susceptible, as confirmed by all pertaining studies, with a reported 4.5:1 to 5:1 ratio of female to male cases. Most often, HH are mono-lesions but multiple-lesions are possible; they account for 2.3% and up to 20-30% of the cases, depending on the source. At the initial diagnosis, the majority of HH measure below 3 cm in size, the so-called capillary hemangiomas; of these, only 10% undergo a size increase with time, for reasons still unknown. The next size class covers lesions between 3 cm and 10 cm in size, referred to as medium hemangiomas. Lastly, giant or cavernous hemangiomas measure up to 10 cm, with occasional literature reports of giant HH reaching 20-40+ cm in size. Location-wise they are most often found in the right liver lobe, often in segment IV, often marginal.

Operative Management

Operative intervention for liver hemangiomas remains a controversial topic. Previous studies from major hepatobiliary centres have proposed varying indications for a hemangioma resection. Findings from the present study demonstrate that operative management of symptomatic hemangiomas remains an effective therapy and can be performed with low morbidity to the patient. However, aside from abdominal symptoms, prophylactic resections in the setting of hemangioma enlargement, size, or patient anxiety is not advised as the risk of developing life-threatening associated complications is rare.

Established Complications. In the minority of cases that present as a surgical emergency due to haemorrhage, rupture, thrombosis and infarction, surgical management may be the only appropriate course of action. There is also a role for the elective surgical management of giant haemangiomata, albeit in a highly selected group of patients. As demonstrated by the data presented above, an operative approach with the objective of preventing future complications of giant haemangiomata is less easy to justify.

Diagnostic Uncertainty. Despite improvements in non-invasive imaging technology, cases of diagnostic uncertainty continue to pose a challenge. In situations where it is not possible to exclude malignancy, surgical intervention by formal liver resection may be indicated. In almost all situations, the use of percutaneous liver biopsy for the differentiation of giant haemangiomata from malignant liver lesions cannot be justified. The risks of haemorrhage as a result of biopsying a giant haemangioma are appreciable and, together with the risks of needle track seeding and intra-abdominal dissemination of a potentially curable malignancy, mean that biopsy in this setting must be avoided.

Incapacitating Symptoms. Having taken all possible steps to ensure that symptoms are attributable to the haemangioma, surgical resection may be justified on grounds of intractable symptoms. Patients with clearly defined abdominal compressive symptoms may be more likely to derive benefit from surgery than patients with non-specific abdominal discomfort, although this is not backed up by a meaningful body of evidence. Management of this group of patients is, by necessity, highly individualised. Despite apparently satisfactory surgical management, symptoms persist in approximately 25% of patients following resection of seemingly symptomatic haemangiomata.

While most people with HH show no sign or symptom, and most HH are non-progressing and do not require treatment, there is a small number of cases with rapid volumetric growth or complications, which prompt for appropriate therapy. The results of clinical and laboratory investigations to date, mostly for imaging techniques, have demonstrated that for small HH, regular follow-up is enough. For cavernous HH, the evolution is unpredictable and often unfavorable, with serious complications requiring particular surgical expertise in difficult cases. Hepatic hemangiomas require a careful diagnosis to differentiate from other focal hepatic lesions, co-occurring diagnoses are also possible.

Management of POST-HEPATECTOMY complications

HEPATECTOMY_OZIMOGAMA

Hepatectomia Esquerda – Metástase CR


Hepatic resection had an impressive growth over time. It has been widely performed for the treatment of various liver diseases, such as malignant tumors, benign tumors, calculi in the intrahepatic ducts, hydatid disease, and abscesses. Management of hepatic resection is challenging. Despite technical advances and high experience of liver resection of specialized centers, it is still burdened by relatively high rates of postoperative morbidity and mortality. Especially, complex resections are being increasingly performed in high risk and older patient population. Operation on the liver is especially challenging because of its unique anatomic architecture and because of its vital functions. Common post-hepatectomy complications include venous catheter-related infection, pleural effusion, incisional infection, pulmonary atelectasis or infection, ascites, subphrenic infection, urinary tract infection, intraperitoneal hemorrhage, gastrointestinal tract bleeding, biliary tract hemorrhage, coagulation disorders, bile leakage, and liver failure. These problems are closely related to surgical manipulations, anesthesia, preoperative evaluation and preparation, and postoperative observation and management. The safety profile of hepatectomy probably can be improved if the surgeons and medical staff involved have comprehensive knowledge of the expected complications and expertise in their management.

Classroom: Hepatic Resections

The era of hepatic surgery began with a left lateral hepatic lobectomy performed successfully by Langenbuch in Germany in 1887. Since then, hepatectomy has been widely performed for the treatment of various liver diseases, such as malignant tumors, benign tumors, calculi in the intrahepatic ducts, hydatid disease, and abscesses. Operation on the liver is especially challenging because of its unique anatomic architecture and because of its vital functions. Despite technical advances and high experience of liver resection of specialized centers, it is still burdened by relatively high rates of postoperative morbidity (4.09%-47.7%) and mortality (0.24%-9.7%). This review article focuses on the major postoperative issues after hepatic resection and presents the current management.

BILIARY-ENTERIC ANASTOMOSIS



Imagem

The operative conduct of the biliary-enteric anastomosis centers around three technical steps: 1) identification of healthy bile duct mucosa proximal to the site of obstruction; 2) preparation of a segment of alimentary tract, most often a Roux-en-Y jejunal limb; and 3) construction of a direct mucosa-to-mucosa anastomosis between these two. Selection of the proper anastomosis is dictated by the indication for biliary decompression and the anatomic location of the biliary obstruction. A right subcostal incision with or without an upper midline extension or left subcostal extension provides adequate exposure for construction of the biliary-enteric anastomosis. Use of retractors capable of upward elevation and cephalad retraction of the costal edges are quite valuable for optimizing visual exposure of the relevant hilar anatomy.

Imagem
Division of the ligamentum teres and mobilization of the falciform ligament off the anterior surface of the liver also facilitate operative exposure; anterocephalad retraction of the ligamentum teres and division of the bridge of tissue overlying the umbilical fissure are critical for optimal visualization of the vascular inflow and biliary drainage of segments II, III, and IV. Cholecystectomy also exposes the cystic plate, which runs in continuity with the hilar plate. Lowering of the hilar plate permits exposure of the left hepatic duct as it courses along the base of segment IVb. In cases of unilateral hepatic atrophy as a result of long-standing biliary obstruction or preoperative portal vein embolization, it is critical to understand that the normal anatomic relationships of the portal structures are altered. In the more common circumstance of  right-sided atrophy, the portal and hilar structures are rotated posteriorly and to the right; as a result, the portal vein, which is typically most posterior, is often encountered first; meticulous dissection is necessary to identify the common bile duct and hepatic duct deep within the porta hepatis.
