BACKGROUND Obesity is among the leading causes of disease and death. Bariatric surgery is the most effective treatment of obesity. There is increasing evidence that after gastric bypass surgery, patients and animal models show a decreased preference for sweet and fatty foods. The underlying mechanism may include alterations in taste function. OBJECTIVE We hypothesize that a gastric bypass red...

PURPOSE Recent studies have demonstrated that mineral and electrolyte abnormalities develop in patients who undergo bariatric surgery. While it is known that these abnormalities are a risk factor for urolithiasis, the prevalence of stone disease after bariatric surgery is unknown. We evaluated the likelihood of being diagnosed with or treated for an upper urinary tract calculus following Roux-e...

Roux-en-Y gastric bypass (RYGBP) is the most commonly performed type of bariatric surgery, which is used in the treatment of obesity and type 2 diabetes. Recent case reports and case series have described a rare complication of RYGBP, status post-gastric-bypass hyperinsulinemic hypoglycemia, which was mainly managed successfully with pancreatectomy. In this letter, we describe the first success...

Currently, the most effective therapy for the treatment of morbid obesity to induce significant and maintained body weight loss with a proven mortality benefit is bariatric surgery. Consequently, there has been a steady rise in the number of bariatric operations done worldwide in recent years with the Roux-en-Y gastric bypass (gastric bypass) being the most commonly performed operation. Against...

BACKGROUND Gastric bypass has repeatedly been shown to improve and even cure type 2 diabetes by substantially improving insulin resistance. The mechanism by which it achieves this is not currently known, but some have hypothesized that there may be important humoral effects brought about by the bypass of the stomach, duodenum or proximal jejunum. A better understanding of the time course of the...

Problems of obesity and its accompanying metabolic disorders remain relevant throughout the world are due to an increased risk disability early mortality in patients with this pathology. Currently, bariatric surgery is recognized as most effective treatment for morbid obesity. Of exceptional importance not only technical features operation, but also a full preoperative examination. The occurren...

The type 2 diabetes mellitus (T2DM) is one of the most serious diseases that threaten public health. Modified gastric bypass surgery has been applied to the treatment of T2DM patients in the 1990s, but the therapeutic mechanism to this function is still unclear. The aim of this study was to further clarify the effect and the mechanism of modified gastric bypass surgery on glucose metabolism in ...

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 ...
