Single-Anastomosis Duodenal Ileostomy with Sleeve Gastrectomy "Continued Innovation of the Duodenal Switch".

Single-anastomosis duodenal ileostomy with sleeve gastrectomy (SADI-S) is an important emerging procedure in bariatric surgery as an alternative to performing the Roux-en-Y gastric bypass (RYGB) or the Roux-en-Y duodenal switch. With this significant weight loss and low weight regain, SADI-S has low complication rates. SADI-S, because of its anatomic configuration, also does not increase ulcer risk in patients, with almost no ulcers observed. Because of the short common channel, malnutrition is a risk. Diabetes resolution is higher than with RYGB. Overall SADI-S is a safe and effective procedure for patients with higher body mass index and patients with diabetes.
