Result

SADI-S (Single anastomosis duodeno–ileal bypass with sleeve gastrectomy) is a bariatric surgical technique to lose weight.

The SADI-S is a type of type of bariatric surgery with a single anastomosis. It has a restrictive component when reducing the greater curvature of the stomach, but specially a malabsorptive component, as the common channel is also reduced. The objective of this surgical technique is to lessen the intestinal loop where nutrients are absorbed.

Technique

It can be performed by laparotomy or 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, 250 centimetres (98 in) from the ileocecal valve. Therefore, the common channel, where nutrients are absorbed becomes 2.5 metres (8.2 ft) long..

Advantages

The SADI-S is a single anastomosis bariatric surgery. It is different than the classic duodenal switch, the gastric bypass (RNY) or sleeve gastrectomy. It is type of bariatric surgery carried out to lose weight.

Disadvantages

Patients may need to take vitamin supplements: A, D, E, K and minerals throughout life. Analytical monitoring is necessary to prevent malnutrition. Stones in the gallbladder, flatulence and diarrhea are more frequent. The surgical risks are the same as in other bariatric techniques, including intestinal perforation, anastomotic leaks, infection, abscess, venous thrombosis and pulmonary embolism. In the long term it can produce a bowel obstruction.
