Single anastomosis duodeno-ileal switch

Single Anastomosis Duodeno-ileal Switch

This is a unique type of bariatric surgery and involves a single surgical anastomosis. The purpose of this unique surgical technique is to reduce the loop of the intestine where nutrients get absorbed. This surgery is recommended for patients with morbid obesity and is based on the biliopancreatic diversion in which a sleeve gastrectomy is followed by an end-to-side duodeno–ileal diversion.

How It Works

The procedure involves a laparoscopic surgery to be performed in which a small gastric sleeve needs to be created by removing the greater part of the stomach, such as in the sleeve technique. This technique offers excellent weight loss and metabolic results.


Single Anastomosis Duodeno-ileal Switch reduces operative time and decreases the possibility of surgically related complications. Patients can get the satisfactory results in weight loss after undergoing this surgery.
