Establishing a reproducible large animal survival model of laparoscopic Roux-en-Y gastric bypass.

Background: The advent of metabolic surgery and the increasing focus on the substantial resolution rate of type 2 diabetes after laparoscopic Roux-en-Y gastric bypass (LRYGB) call for additional fundamental investigations as to the mechanisms behind this effect. These investigations require an adequate animal model. Our objective was to develop a reproducible survival model of LRYGB performed in a large animal at a tertiary university hospital.

Gastrointestinal complications after lung transplantation.

Background: Gastrointestinal complications after lung transplantation remain a common yet poorly defined problem. In this study we examine our experience with gastrointestinal complications after lung transplantation.

Methods: Between August 1990 and June 2005, we retrospectively analyzed 208 patients who had undergone lung transplantation (single, 65% [137 of 212]; double, 34% [72 of 212]; heart-lung, 0.

Bariatric operations in Veterans Affairs and selected university medical centers: results of the patient safety in surgery study.

Background: The objectives of this study were to evaluate outcomes and predictors of morbidity in patients undergoing Roux-en-Y gastric bypass (RYGB) during the Patient Safety in Surgery (PSS) Study.

Study Design: National Surgical Quality Improvement Program data on PSS patients undergoing RYGB were analyzed for unadjusted and adjusted outcomes. Gender groups acted differently and were analyzed separately.
