Computed tomography assessment of postoperative gastric vascular supply and staple-line leak development after sleeve gastrectomy
Background: Residual arterial supply of the gastric tube after sleeve gastrectomy (SG) can be damaged by surgery, which can reduce gastric tube perfusion and could promote postoperative leakage. Objective: To compare the postoperative vascularization of the gastric tube using early computed tomography (CT) scanning after SG in patients with or without postoperative staple-line leak. Setting: University hospital. Methods: A retrospective analysis of a prospective database was performed in consecutive patients undergoing SG. Patients who presented with a staple-line leak were matched (1:3) with a control group of patients who underwent surgery without postoperative morbidity during the same period. Gastric tube vascularization was studied on a postoperative day 2 CT scan in both groups of patients. Results: During the study period, 1826 patients underwent SG, including 42 patients (2.3%) who presented with a staple-line leak. Those 42 patients were successfully matched to 126 control patients. Global identification of residual gastric arterial supply in early postoperative CT scans was similar in patients with or without staple-line leak after SG. However, residual vascular supply of the gastroesophageal junction (i.e., terminal and anterior cardiotuberosity branches of the left gastric artery or left inferior phrenic artery) was more frequently interrupted by the staple line in the group of patients who developed a gastric leak. Conclusion: This study suggests a correlation between interruption of the main arteries supplying the gastroesophageal junction by the staple line on early postoperative CT scans and the development of gastric leak after SG. These results support the vascular theory as one of the causes of leak after SG
International multicenter expert survey on endoscopic treatment of upper gastrointestinal anastomotic leaks
Background and study aims: A variety of endoscopic techniques are currently available for treatment of upper gastrointestinal (UGI) anastomotic leaks; however, no definite consensus exists on the most appropriate therapeutic approach. Our aim was to explore current management of UGI anastomotic leaks. Methods: A survey questionnaire was distributed among international expert therapeutic endoscopists regarding management of UGI anastomotic leaks. Results: A total of 44 % of 163 surveys were returned; 69 % were from gastroenterologists and 56 % had > 10 years of experience. A third of respondents treat between 10 and 19 patients annually. Fifty-six percent use fully-covered self-expandable metal stents as their usual first option; 80% use techniques to minimize migration; 4 weeks was the most common reported stent dwell time. Sixty percent perform epithelial ablation prior to over-the-scope-clip placement or suturing. Regarding endoscopic vacuum therapy (EVT), 56 % perform balloon dilation and intracavitary EVT in patients with large cavities but small leak defects. Regarding endoscopic septotomy, 56 % consider a minimal interval of 4 weeks from surgery and 90 % consider the need to perform further sessions. Regarding endoscopic internal drainage (EID), placement of two stents and shorter stents is preferred. Persistent inflammation with clinical sepsis was the definition most commonly reported for endoscopic failure. EVT/stent placement and EVT/EID were the therapeutic options most often chosen in patients with previous oncologic surgery and previous bariatric surgery, respectively. Conclusions: There is a wide variation in the management of patients with UGI anastomotic leaks. Future prospective studies are needed to move from an expert- to evidence- and personalization-based care
Operative management of acute abdomen after bariatric surgery in the emergency setting: the OBA guidelines
Background: Patients presenting with acute abdominal pain that occurs after months or years following bariatric surgery may present for assessment and management in the local emergency units. Due to the large variety of surgical bariatric techniques, emergency surgeons have to be aware of the main functional outcomes and long-term surgical complications following the most performed bariatric surgical procedures. The purpose of these evidence-based guidelines is to present a consensus position from members of the WSES in collaboration with IFSO bariatric experienced surgeons, on the management of acute abdomen after bariatric surgery focusing on long-term complications in patients who have undergone laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass.
Method: A working group of experienced general, acute care, and bariatric surgeons was created to carry out a systematic review of the literature following the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) and to answer the PICO questions formulated after the Operative management in bariatric acute abdomen survey. The literature search was limited to late/long-term complications following laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass.
Conclusions: The acute abdomen after bariatric surgery is a common cause of admission in emergency departments. Knowledge of the most common late/long-term complications (> 4 weeks after surgical procedure) following sleeve gastrectomy and Roux-en-Y gastric bypass and their anatomy leads to a focused management in the emergency setting with good outcomes and decreased morbidity and mortality rates. A close collaboration between emergency surgeons, radiologists, endoscopists, and anesthesiologists is mandatory in the management of this group of patients in the emergency setting
Superior Mesenteric Artery Syndrome—Believe in it! Report of a Case
We present a case of a man with amyotrophic lateral sclerosis who developed superior mesenteric artery syndrome (SMAS) following the confection of feeding jejunostomy. He was successfully managed by conservative treatment. Left lateral positioning during enteral feeding allowed quick resolution of the occlusive state. Various surgical interventions have been associated with SMAS, directly or indirectly, by reducing the width of the aortomesenteric angle. The operative stress was probably what triggered symptomatology in our patient thus to conclude that the surgical stress should be considered as a causal factor triggering the SMAS in a context of other predisposing factors
Difficult biliary stones in the elderly. Endoscopic retrograde cholangiography. A single surgical tertiary centre experience with follow-up
Background: Pancreaticobiliary diseases and choledocholithiasis are common in elderly patients. Endoscopic treatment of biliary stones represents a well-established mini-invasive technique. However, limited data are available regarding the treatment of 'difficult' biliary stones, especially in the elderly population. The aim of our study is to evaluate the efficacy and safety of therapeutic endoscopic retrograde cholangiopancreatography (ERCP) in patients ≥85 years of age with complex biliary stones.Materials and Methods: From January 2015 to January 2017, data from ERCP procedures performed for complex biliary stones were retrospectively collected. The patients were divided into two groups based on their age: Group A - aged 85 years or older (n = 110) and Group B - aged 65 years or younger (n = 62). Demographic data, success, complications and recurrence rates for both groups were reported.Results: Chronic comorbidities (86.3% vs. 24.2%; P < 0.001) and use of antithrombotic drugs (48.2% vs. 19.3%; P < 0.001) were more frequent in the elderly. The technical success rate (95.4% vs. 96.7%; P > 0.6) and complication rate (8.2% vs. 13%; P > 0.2) were not statistically different among the two groups. Periampullary diverticula (PAD) were observed more frequently in Group A (38.1% vs. 17.7%; P < 0.006). More patients from Group B underwent cholecystectomy during the same admission (8.2% vs. 42.3%; P < 0.001). The recurrence rate was not different among the groups (7.6% vs. 5%; P > 0.5). PAD was identified as the risk factor for recurrence (P < 0.02).Conclusion: ERCP in the elderly was found to be a safe procedure, carrying a high degree of success for the treatment of difficult biliary stones
