SADI-s
(SINGLE ANASTOMOSIS DUODENO ILEAL BYPASS)

It is a novel surgery similar to the minigastric bypass. It consists of doing a bypass of one anastomosis only, but with a larger gastric reservoir that preserves the esophageal distal sphincter (pylorus) and performs the anastomosis to the duodenum.

History

First described by A. Sánchez –Pernaute; it is also known as one anastomosis duodenal switch. It is gaining popularity since it is a simpler technique than the duodenal switch, however, it is a technique with potential for more serious complications. These have prevented it from being more widespread.

Weight loss and illness resolution

• Similar results to duodenal switch. Better results than the gastric bypass because of its increased malabsorption.

• Good quality of life.

• Similar mortality and morbidity to the rest of techniques, if the surgeon is an expert.

• Very good resolution of comorbidies.

Indications

• Revisional surgery after gastric sleeve because of lack of improvement in diabetes, or because of  poor weight loss results

• Diabetic patients and/or for metabolic syndrome

• BMI > 50
