SADI-S (Single anastomosis duodenal-ileal bypass with sleeve)

Single anastomosis duodeno–ileal bypass with sleeve gastrectomy is a new bariatric surgical procedure to lose weight.

The SADI-S is a type of laparoscopic bariatric surgery with a single surgical anastomosis (duodeno-ileal bypass) and creation of a small gastric sleeve such as in the sleeve technique. The technique can be more effective because of the combination of gastric bypass and gastric sleeve and in comparison to the gastric sleeve – additional performing of the intestinal loop where nutrients are absorbed.

Technique used for SADI-S

It can be performed by laparoscopy. A small gastric sleeve is created by sectioning the greater curvature of the stomach, such as in the sleeve technique. Subsequently, the duodenum is transected respecting the pylorus. A duodenum-intestinal anastomosis is carried out between 250 centimeters (98 in) and 300 centimeters (120 in) from the ileocecal valve. Therefore, this distance becomes the length of the common channel where nutrients are absorbed.
