Evaluation of Laparoscopic Single Anastomosis Duodenoileal Bypass-Sleeve Gastrectomy in Bariatric Surgery

Abstract

Single anastomosis duodenoileal bypass with sleeve gastrectomy (SADIS) is a new bariatric technique based on the biliopancreatic diversion with duodenal switch in which after the sleeve gastrectomy, the duodenum is anastomosed to the ileum in a Billroth-II fashion. A 250-cm common channel alimentary limb is devised. Anticipating an appropriate weight loss, at least similar to that obtained after gastric bypass. Benefits for operated patients are a shorter operative time, the performance of only one anastomosis, and no mesentery opening. Key words: Biliopancreatic diversion, Duodenal switch, Gastric bypass, Metabolic surgery, Mini Gastric bypass, Morbid obesity, Single anastomosis, Sleeve Gastrectomy
