Introduction:
Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) has become the gold standard for surgical weight loss in the morbidly obese. The success of LRYGB may be measured by excess weight loss (EWL), and several variables have been identified as independent pre-operative predictors of EWL. However, current models of estimating EWL, based on multivariate regression analysis, are poorly prognostic. Artificial neural networks (ANN) are advanced, continually adapting computational systems taught
Introduction:
With an estimated 15 million Americans morbidly obese and the numbers growing, bariatric surgery’s role will continue. The primary mechanisms through which bariatric surgery achieves its outcomes are through the mechanical restriction of food intake, reduction in the absorption of ingested foods, or a combination of both. In addition to these malabsorptive and restrictive mechanisms, hormonal changes also play a role. Roux-en-Y Gastric Bypass (RYGB) and Vertical sleeve gastrectomy
Introduction: Biliary disease is a common complication in bariatric surgery patients. The purpose of this study is to determine whether an association exists between the type of bariatric surgery performed and the incidence of biliary disease.
Methods and Procedures: We retrospectively reviewed all vertical sleeve gastrectomy (n=300), roux en-Y gastric bypass (n=2120), and gastric lap band procedures (134) performed at our institution between 2002 and 2012. Primary endpoints included the type o
Introduction
Laparoscopic sleeve gastrectomy (LSG) has become a standard procedure in the bariatric surgeons’ armamentarium for obesity surgery. Recognized as a standalone procedure, there has been a recent increase in the number of procedures performed. As the number of cases increase, so do the number of complications. Staple line leak can be a devastating morbidity, which can consume health care resources as well as be detrimental to the patient. Just as the technique for the LSG has e
Introduction
Laparoscopic sleeve gastrectomy (LSG) has become an acceptable primary stand-alone procedure for metabolic and weight-loss surgery. Traditional LSG involves multiple small abdominal incisions, similar to traditional laparoscopic cholecystectomy. Sleeve gastrectomy has also been performed using the single incision laparoscopic surgery (SILS) technique, to minimize scarring and improve ultimate cosmetic outcome. SILS is technically challenging due to the crossover of instruments. Rec
