In 2020, the American Society for Metabolic and Bariatric surgery endorsed the SADI-S surgery as yet another effective form of bariatric surgery. This procedure is a combination of a gastric bypass and a gastric sleeve. Utilizing the best components of each procedure, the SADI-S is ideal for patients with a BMI of 50+ and for those with type 2 diabetes.

SADI-S Surgery (Single Anastomosis Duodenal-Ileal Bypass with Sleeve Gastrectomy)
How SADI-S surgery is performed
The first half of this laparoscopic procedure involves performing the sleeve gastrectomy. During surgery, a bariatric surgeon divides the upper portion of the stomach from the lower portion leaving a tube-shaped “sleeve” to serve as the stomach. Approximately 80-85% of the stomach is removed.
Following the sleeve portion of the procedure, our surgeons re-route the first part of the small intestine so food bypasses them, thus preventing the body from absorbing the full amount of calories consumed.
The Benefits of SADI-S Surgery
- The procedure is performed laparoscopically resulting in shorter recovery, smaller incisions, and less pain.
- Because it is combining the best aspects of the gastric bypass and gastric sleeve, patients feel fuller longer because the majority portion of the stomach that generates ghrelin, the hormone that stimulates hunger, is removed. In addition, by bypassing the first part of the small intestine, optimization of blood sugar levels is more easily achieved.
- This procedure is simpler to perform than a gastric bypass and only results in a single anastomosis as opposed to two.
- For patients with a previous history of a gastric sleeve requiring further weight loss, this will be an excellent option to assist with continuing their weight loss journey.
SADI-S Weight Loss: What Can You Expect?
Published studies on weight loss report an average of 50-85% excess weight loss (EWL) after SADI-S surgery.
Weight loss after surgery is commonly described by the percentage of excess weight lost (%EWL). Excess weight is the amount of weight over ideal weight.

Please Note: The excess weight loss listed above is just an average. A patient can lose more or less than the average amount of expected excess weight loss based upon how well they follow the program guidelines.
