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...

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...

BACKGROUND Obesity has recently been cited as the number one killer in the USA. This problem is both a national and regional epidemic. The health care costs of obesity and obesity-related illnesses are ever increasing, and gastric bypass surgery is becoming a popular treatment strategy. Recently, reports describe not only surgical outcomes, but also quality of life outcomes. The bigger issue of...

The incidence of diabetes has been increasing over previous years. It is hypothesized that promoting the survival of islet β-cells is a key direction for the treatment of diabetes. Although gastric bypass surgery improves certain types of diabetes and attenuates its progression, there are certain associated disadvantages (including intestinal obstruction and anastomotic leakage), and quality of...

BACKGROUND Currently, bariatric surgery is the most effective therapy for morbid obesity, and the laparoscopic approach is considered gold-standard for Roux-en-Y gastric bypass. Totally robotic Roux-en-Y gastric bypass has been proposed as a major evolution in minimally invasive bariatric surgery and its use is becoming more widespread. AIM To provide an early report of the first Brazilian ca...

BACKGROUND The literature reports that gastrojejunal derivation with Roux-en-Y gastric bypass is highly efficient in controlling weight and resolving; but studies have shown worsened glycemic control in a considerable number of patients and associated factors that have not been fully elucidated. AIM To analyze the profile of patients submitted to gastric bypass that did not achieve satisfacto...

The objective was to examine the relationship between fulfilment of expectations and health-related quality of life 4 and 12 months after gastric bypass. A follow-up study based on patients undergoing gastric bypass at Aalborg Hospital - Aarhus University Hospital during February 2008 to December 2009. Health-related quality of life was assessed by Short Form 36 and summarized into the physical...

CONTEXT Roux-en Y gastric bypass surgery is the most common operation for treatment of morbid obesity. The approach to pancreaticoduodenal resection in patients with a history of Roux-en Y gastric bypass is not well described. CASE REPORTS Pancreaticoduodenal resection was performed in two patients with distal bile duct strictures, with a past history of Roux-en Y gastric bypass. In both case...

INTRODUCTION Bariatric surgery is a method of treating morbid obesity, which has been raising more and more interest in the past years. Among all types of intervention, the most frequently used is Roux-en-Y gastric bypass, an intervention both restrictive and malabsorptive, which leads to best results in weight loss. In Romania, bariatric surgery, and especially Roux-en-Y gastric bypass, is not...

BACKGROUND Gastric bypass surgery seems to have an effect on glucose metabolism beyond what is mediated through weight reduction. The magnitude of this effect on fasting and post-challenge glucose levels remains unknown. RESULTS Morbidly obese subjects without known diabetes performed a 75 g oral glucose tolerance test before and after either gastric bypass surgery (n = 64) or an intensive li...
