Gastric bypass leads to the remission of type 2 diabetes independently of weight loss. Our hypothesis is that changes in bile flow due to the altered anatomy may partly explain the metabolic outcomes of the operation. We prospectively studied 12 patients undergoing gastric bypass and six patients undergoing gastric banding over a 6-wk period. Plasma fibroblast growth factor (FGF)19, stimulated ...

Abstract Background: Laparoscopic One-anastomosis gastric bypass (LOAGB) has proved to be safe and effective, with short learning curve low morbidity rate. Methods: This was a prospective

INTRODUCTION Single anastomosis gastric bypass (one anastomosis gastric bypass or mini-gastric bypass) has been presented as an option of surgical treatment for obese patients in order to reduce operation time and avoiding eventual postoperative complications after Roux-en-Y gastric bypass.The main late complication could be related to bile reflux. AIM To report the experiences published afte...

BACKGROUND Weight loss causes changes in appetite and energy expenditure that promote weight regain. Ghrelin is a hormone that increases food intake in rodents and humans. If circulating ghrelin participates in the adaptive response to weight loss, its levels should rise with dieting. Because ghrelin is produced primarily by the stomach, weight loss after gastric bypass surgery may be accompani...

OBJECTIVE Use of gastric bypass surgery is common and increasing. Over 40% of patients in diabetes remission after gastric bypass surgery may redevelop diabetes within 5 years. Metformin, the first-line drug for diabetes, has low bioavailability and slow, incomplete gastrointestinal absorption. We hypothesized that gastric bypass would further reduce the absorption and bioavailability of metfor...

BACKGROUND The recent article by Guller, Klein, Hagen was reviewed and discussed by the authors of this response to critically analyze the validity of the conclusions, at a time when patients and providers depend on peer reviewed data to guide their health care choices. The authors of this response all have high volume bariatric surgery practices encompassing experience with both gastric bypass...

The study aimed to examine the effect of gastric bypass on diabetic nephropathy (DN) in Chinese patients. A retrospective study of 101 samples with DN stages I to IV underwent Roux-en-Y gastric bypass. Anthropometric and biochemical parameters were assessed during a 1-year follow-up. Binary logistic regression analysis was used for predictors and ROC for cutoff points. There was significant red...

A 40-year-old woman presented with small bowel obstruction caused by an internal hernia through Peterson's defect. The patient was known to have midgut malrotation (MM) and also had laparoscopic Roux-en-Y gastric bypass for morbid obesity 6 years prior. An open revision of Roux-en-Y gastric bypass was performed as a result of ischemia of alimentary limb. She made a slow but uneventful recovery ...

RESULTSdGlycemic control improved in all three groups at 24months (N5 54), with amean HbA1c of 6.76 1.2% for gastric bypass, 7.16 0.8% for sleeve gastrectomy, and 8.46 2.3% for IMT (P , 0.05 for each surgical group versus IMT). Reduction in body fat was similar for both surgery groups, with greater absolute reduction in truncal fat in gastric bypass versus sleeve gastrectomy (216 vs.210%; P5 0....

INTRODUCTION Nutrition counseling is important for veterans undergoing gastric bypass surgery. The aim of this study was to explore the relationship between the number of nutrition visits a patient attended and change in body mass index (BMI) after gastric bypass surgery for the veteran population. METHODS A retrospective study examined veterans (N = 79) who underwent Roux-en-Y gastric bypass...
