INTRODUCTION In bariatric surgery, still new surgical techniques are developed. On the one hand, the Roux-en-Y gastric bypass (RYGB) is one of the most common procedures used. However, many patients experience dumping syndrome or pain due to bile reflux. On the other hand, revisions after gastric banding are frequent and may be technically challenging. AIM To create a new bariatric procedure ...

BACKGROUND Proximal Roux-en-Y gastric bypass may not ensure adequate weight loss in superobese patients. Bypassing a longer segment of the small bowel may increase weight loss. The objective of the study was to compare the perioperative outcomes of laparoscopic proximal and distal gastric bypass in a double-blind randomized controlled trial of superobese patients. The study was conducted at two...

There has been increasing interest in the role that gut hormones may play in contributing to the physiological changes produced by certain bariatric procedures, such as Roux-en-Y gastric bypass and sleeve gastrectomy. Here, we review the evidence implicating one such gut hormone, glucagon-like peptide-1, as a mediator of the metabolic benefits of these two procedures.

The problem of revision of failed vertical banded gastroplasty (VBG) has become a common situation in bariatric surgery. Sleeve gastrectomy (SG) has been recently used to revise failed restrictive procedures. This study presents a patient that is treated with Roux-n-Y gastric bypass because of mesh migration after SG for revision of failed VBG.

We report a rare case of complicated jejunal diverticulitis in a patient with previous bariatric surgery. Small bowel diverticulosis is generally considered an inoffensive disease. In this report we describe a case of small bowel perforation in an obese subject who had undergone laparoscopic Roux-en-Y gastric bypass.

Biliopancreatic limb obstruction after laparoscopic Roux-en-Y gastric bypass is a challenging diagnosis as the symptoms are very nonspecific. CT scan is the optimal study for evaluation. Early diagnosis and treatment is essential in reducing the morbidity and mortality associated with this condition.

Heterotopic mesenteric ossification (HMO) is a rare entity with few cases reported in the world literature. We report two cases. Both patients underwent an open gastric bypass with Roux-en-Y reconstruction procedure for morbid obesity and subsequently presented with gastrointestinal fistulae associated with HMO.

Marginal ulcers are reported to be the most common complication following Roux-en-Y gastric bypass surgery. Despite their frequency, they are rarely diagnosed prospectively with cross-sectional imaging. We present four cases in which the diagnosis of marginal ulceration was made prospectively with CT and confirmed with endoscopy.

Marginal ulceration at the gastrojejunal anastomosis is a common complication following Roux-Y gastric bypass (RYGB). Hemodynamically significant hemorrhagic marginal ulcers are usually treated either endoscopically or surgically. We describe a unique case of life-threatening hemorrhagic marginal ulcer eroding into the main splenic artery. This condition was initially managed with angiographic ...
