Alterations in gastrointestinal physiology after Roux-en-Y gastric bypass.

Changes in gastrointestinal hormones and leptin after Roux-en-Y gastric bypass procedure: a review.

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...

Bleeding duodenal ulcer after Roux-en-Y gastric bypass surgery: the value of laparoscopic gastroduodenoscopy

Postoperative upper gastrointestinal bleeding, though rare, is a potentially fatal complication of gastric bypass surgery that usually occurs a few months postoperation. The current report describes a 57-year-old man with a bleeding duodenal ulcer who underwent Roux-en-Y gastric bypass surgery 12 years earlier. With an increasing number of gastric bypass surgeries performed each year, physician...

Gastrointestinal hemorrhage after laparoscopic gastric bypass.

Gastrointestinal hemorrhage is a potential perioperative complication after Roux-en-Y gastric bypass. The surgeon performing laparoscopic gastric bypass should understand the need for early recognition and management of this complication, as it can be life-threatening. This paper discusses the incidence and clinical presentation of gastrointestinal hemorrhage, mechanisms for hemorrhage, managem...

Comparison of roux-en-y gastric bypass techniques with and without distal gastric plication in patients with morbid obesity

Impact of Roux-en-Y gastric bypass surgery on rat intestinal glucose transport.

Roux-en-Y gastric bypass (RYGB) has become the gold-standard bariatric procedure, partly because of the rapid resolution of accompanying diabetes. There is increasing evidence this is mediated by duodenal exclusion. We hypothesize that duodenal exclusion suppresses intestinal Na(+)/glucose cotransporter SGLT1-mediated glucose transport, improving glucose handling, and aimed to test this in a ro...

A Case Report on Complicated Bleeding in a Patient Post Roux-En-Y Gastric Bypass

Roux-en-Y gastric bypass (RYGB) is a fairly routine surgical procedure for treating patients with morbid obesity. Since postoperative upper gastrointestinal bleeding (GI) is uncommon and etiologies in these patients can be variable, investigation and treatment can be difficult in the post-surgical patient. We report a case of a 65 year-old female, post Roux-en-Y bariatric surgery who presented ...
