10-40% of Roux-en-Y gastric bypass (RYGB) patients regain significant weight after Roux-en-Y gastric bypass surgery due to dilation of the pouch and/or the gastrojejunal (GJ) anastomosis. Traditional revision surgery is associated with significant morbidity (e.g. post-anastomotic GJ leak) where less invasive endoluminal procedures may represent safer alternatives. The present article reports a ...

BACKGROUND Bariatric surgery is an effective treatment to obtain weight loss in severely obese patients. The feasibility and safety of bariatric robotic surgery is the topic of this review. METHODS A search was performed on PubMed, Cochrane Central Register of Controlled Trials, BioMed Central, and Web of Science. RESULTS Twenty-two studies were included. Anastomotic leak rate was 8.51% in ...

Roux-en-Y gastric bypass is a well-accepted tool for the treatment of obesity and, compared to conventional weight loss methods (eg, diet and exercise) and other weight loss surgeries (eg, gastric banding), it results in considerable weight loss that is maintained long term. Although successful, the mechanisms for weight loss are not completely understood and it is thought that gastrointestinal...

CONTEXT Causal factors of gastrojejunal ulcers after Roux-en-Y gastric bypass include peptic acid secretion from the gastric pouch. Esomeprazole is a potent inhibitor of acid secretion. OBJECTIVE To assess the occurrence of dyspepsia and gastrojejunal ulcers within the first 2 months after Roux-en-Y gastric bypass during the use of esomeprazole. METHODS One hundred eighteen morbid obese sub...

BACKGROUND Surgical options for morbid obesity are diverse, and the Roux-en-Y gastric bypass, initially described by Fobi has gained popularity. Knowledge about the physiology of the bypassed stomach is limited because this newly produced segment of the stomach is inaccessible to endoscopic or contrast radiological studies. AIM To evaluate the myoelectric activity of the bypassed stomach and ...

Bowel obstruction is a known complication of Roux-en-Y gastric bypass. It can be caused by adhesions, internal hernia, incarcerated ventral hernia, or intussusception. Sometimes the underlying cause may be unusual. These 2 case reports describe patients who underwent laparoscopic Roux-en-Y gastric bypass and whose postoperative courses were complicated by small-bowel obstruction due to phytobez...

Postprandial symptoms of neuroglycopenia after bariatric surgery may result as a consequence of endogenous hyperinsulinemic hypoglycemia (nesidioblastosis) not dumping syndrome. Pancreatectomy is an acceptable treatment for this condition. We present the video of a case of near-total distal robotic pancreactectomy for the treatment of nesidioblastosis after Roux-en-Y gastric bypass. Robotic pan...

Worldwide, there have been <25 reported cases of hyperammonemic encephalopathy associated with Roux-en-Y gastric bypass surgery in the absence of cirrhosis. We describe a 42-year-old woman who presented with subacute but progressive neurological decline late in her postoperative course, which deteriorated despite multiple conservative and aggressive measures, including hemodialysis, in an attem...

This report describes a rare case of adult intussusception in a patient with a history of a Roux-en-Y gastric bypass procedure; complicated by a history of narcotic abuse, methadone dependence, and methamphetamine abuse. Adult patients who have undergone a Roux-en-Y gastric bypass procedure may be at an increased risk of developing intussusception, and clinicians involved in their care should b...
