Short-Term Results of Single-Anastomosis Gastric Bypass After Failed Sleeve Gastrectomy

Abstract

Accumulating evidence obviously supports the superiority of weight loss surgery over non-surgical treatments for management of morbidly obese patients in terms of outcomes as sustained weight loss, improved quality of life and prevention, reduction, or resolution of co-morbidities (e.g., T2DM, dyslipidemia), as well as reduced overall mortality. However, weight loss failure/weight regain is a well- recognized issue after bariatric surgery. To date, no clear consensus has been reached on a numerical definition for weight recidivism (i.e., % weight regained). Weight recidivism varies according to the length of follow-up and the bariatric procedure performed, being especially prevalent after procedures which lack an intestinal bypass. Recently, it has been estimated that approximately 37% of SG patients will eventually require a secondary operation to account for weight recidivism after 10 years. This might involve either a redo (Resleeve gastrectomy), conversion to another bariatric procedure [e.g., Gastric Bypass, duodenal switch], or adding an adjustable gastric band.
