Mini-gastric bypass: Prevention and management of complications in performance and follow-up.

The mini-gastric bypass (MGB) has proven to be a safe, rapid and effective weight-loss procedure. However, as with all abdominal operations, complications may still occur, and should be prevented if possible and treated appropriately. The authors discuss experience with the MGB.

Esophagogastric junction function and gastric pressure profile after minigastric bypass compared with Billroth II.

Background: Minigastric bypass (MGB) is being performed widely with effective weight loss and improvement in co-morbidities. Because of similarity to Billroth II (BII), there are concerns about bile reflux.

Objectives: To assess the esophagogastric junction (EGJ) function, esophageal peristalsis, and reflux exposure after MGB and BII.

The Evaluation of Screening Questionnaires for Obstructive Sleep Apnea to Identify High-Risk Obese Patients Undergoing Bariatric Surgery.

Background: Obstructive sleep apnea (OSA) is extremely common among bariatric surgical candidates. Identifying those at risk for moderate to severe OSA is challenging. Testing all bariatric surgical candidates with a level 1 polysomnographic study is expensive and resource intensive.

The Effects of One-Anastomosis Gastric Bypass on Glucose Metabolism in Goto-Kakizaki Rats.

Background: The improvement in glucose metabolism after bariatric surgery is well established. The aim of this study was to investigate the hormones and glycemic control in diabetes after a one-anastomosis gastric bypass (OAGB) variant in an animal model of non-obese type 2 diabetes mellitus.

Methods: Thirty-six Goto-Kakizaki rats were randomly assigned to undergo one of the following procedures: OAGB (18 rats) or sham intervention (18 rats).

Bariatric surgical practice revisited: unrecorded or overlooked problems in the severely obese.

Severe loss of activities of daily living, if noted, is a potent reason for weight-loss surgery.

A brief history of the surgery for obesity to the present, with an overview of nutritional implications.

Massive obesity results in serious diseases, which are a major public health problem. Surgery is frequently the only means to achieve and sustain significant weight loss. This historical overview is aimed at providing knowledge and appreciation of this surgery to scientists in other complex areas of nutrition.
