Single Anastomosis Duodeno–Ileal Bypass with Sleeve Gastrectomy FAQs

Learn more about SADI-S here. 

Single Anastomosis Duodeno–Ileal Bypass with Sleeve Gastrectomy, or SADI-S as it is commonly known, is a modified version of the duodenal switch procedure. SADI-S combines the benefits of both intestinal bypass and sleeve gastrectomy to effectively treat morbid obesity. During the procedure, a large portion of the stomach is removed in order to reduce one’s capacity to eat and to reduce one’s level of ghrelin (the hunger hormone), while the top part of the small bowel is divided so that food bypasses part of the small intestine. This works by reducing the number of fats, sugar and calories that are absorbed by the body.

According to studies, the SADI-S procedure is able to provide greater weight loss than either a standard sleeve gastrectomy or gastric bypass procedure. Because the surgery combines the benefits of sleeve and bypass operations, it is often a very effective treatment for those who are morbidly obese. The surgery also has less risk of dumping and diarrhoea than other forms of bypass, and there also tends to less risk of internal hernia when compared to other surgical weight loss options.

The SADI-S procedure tends to be a much longer operation than the other surgical weight loss options that are currently available. As a result, the anaesthetic time is longer than the other procedures. There is also an increased risk of leakage with SADI-S. This is because there are two staple lines — one for the sleeve and one for the bypass. Dr Dolan will advise you as to whether SADI-S is the best option for you, depending on your particular circumstances and health condition. He will also let you know about any other options available to you.
