Result

The SADI-S is a type of bariatric surgery with a single surgical anastomosis. It has a restrictive component when reducing the greater curvature of the stomach, but especially 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 from the classic duodenal switch, the gastric bypass (RNY) or sleeve gastrectomy. It is a type of bariatric surgery carried out to lose weight.

Disadvantages

Patients will need to take vitamin supplements A, D, E, K and minerals throughout their lives. Analytical monitoring is necessary to prevent malnutrition. Stones in the gallbladder, flatulence and diarrhea are more frequent. The surgical risks are similar 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. There is a greater chance of bile reflux than a traditional duodenal switch. As of 2018, it is still classified as experimental by all insurance companies and has no long term follow-up data. There is no research to indicate that it has any significant reduction in vitamin or mineral supplementation as compared to the classic duodenal switch.
