Background: Bariatric surgery is the most efficient therapy for morbid obesity. Staple line and anastomotic leakage are the most feared postoperative complications after Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy (LSG). Traditional treatment options like revisional surgery and endoscopic stent placement are associated with high morbidity and mortality as well as variable success rates. Endoscopic vacuum therapy (EVT) has shown to be a new successful and feasible treatment option for leaks of different etiology after major gastro-esophageal surgery.
Method: We report a case of the EVT principle being applied in a patient with three major leaks located apart from each other within the gastric staple line after LSG for morbid obesity (BMI 62.7). EVT was initiated on postoperative day 8.
Results: In total, 18 endoscopic interventions were performed in 72 days, the vacuum sponge being replaced endoscopically every 4 days. Hospital length of stay was 106 days. No relevant procedure related complications were observed during the course of therapy and during the follow up.
Conclusion: EVT of postoperative leaks in the upper GI tract has been shown to be feasible and safe. It combines defect closure and effective drainage and allows a periodic inspection of the wound cavity. In case of therapeutic failure, it does not jeopardize surgical repair or stent placement. Even though the techniques and materials used in EVT still vary considerably according to local expertise, EVT has the potential to succeed as a nonsurgical, feasible, safe, and effective treatment option for postoperative leaks in bariatric surgery.

Background: Bariatric surgery is the most long-term effective treatment option for severe obesity. The role of gut microbiome (GM) in either the development of obesity or in response to obesity management strategies has been a matter of debate. This study aims to compare the impact of two of the most popular procedures, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (GB), on metabolic syndrome parameters and gut bacterial microbiome and in systemic immuno-inflammatory response.

This study investigates the effects of Roux-en-Y gastric bypass (RYGB) on fibrotic MASH, assessed using the fibrotic NASH index (FNI) and the non-invasive NASH detection score (NI-NASH-DS), as well as provides further data on the diagnostic accuracy of both scores.

Background: Previous studies have demonstrated Black-vs-White disparities in postoperative outcomes following primary metabolic and bariatric surgery (MBS). With the rising prevalence of MBS, it is important to examine racial disparities using quality indicators in primary and revisional procedures. This study explores Black-vs-White disparities in postoperative outcomes following primary and revisional MBS.

Background: Safety in one anastomosis gastric bypass (OAGB) is judged by outcomes, but it seems reasonable to utilize best practices for safety, whose performance can be evaluated and therefore improved. We aimed to test an artificial intelligence-based model in real world for the evaluation of adherence to best practices in OAGB.Please check and confirm that the authors and their respective affiliations have been correctly identified and amend if necessary.

Background: Defect closure with mesh suture is a novel technique for hernia repair. Originally described as the construction of lightweight macroporous polypropylene mesh strips as a suture material, it is now available as an FDA-approved product. Mesh suture better distributes tensile forces and reduces fascial tearing compared to traditional suture but requires less implanted material and tissue dissection compared to planar mesh.
