About single anastomosis duodenal-ileal (SADI) surgery
SADI surgery uses two bariatric surgery procedures — gastric sleeve surgery and gastric bypass surgery — to provide very aggressive weight loss. It is often recommended for people with a BMI greater than 50 or those who have not lost enough weight from gastric sleeve surgery alone. Our bariatric surgeons at Scripps use the latest in minimally invasive (laparoscopic) techniques. By making only a few small incisions during surgery, laparoscopic SADI surgery may result in less pain, shorter hospitalization, decreased risk of complications, shorter recovery time and better cosmetic results.
How does SADI surgery work?
SADI surgery helps promote weight loss in two ways:
- By restricting the amount of food your stomach can hold and, subsequently, the calories you consume, with a gastric sleeve.
- By shortening or “bypassing” part of your small intestine, which reduces the amounts of calories and nutrients your body absorbs.
Because your body absorbs fewer nutrients following SADI surgery, you’ll need to take nutritional supplements daily.
What happens during SADI surgery?
SADI surgery involves two procedures.
First, your surgeon permanently reduces the size of your stomach by 80% through gastric sleeve surgery. The remaining portion, which is shaped like a tube or “sleeve,” can hold only about two ounces of food at any given time. For comparison, an average stomach can hold up to two quarts. In addition, reducing the stomach size also reduces the production of ghrelin, a hormone which sends hunger signals to the body.
Next, your surgeon re-routes part of your small intestine to your remaining stomach, bypassing about 75% of your digestive system. During the normal digestive process, your small intestine absorbs calories and nutrients. Following surgery, once food leaves your stomach it will bypass the top portion of your small intestine, so your body will absorb fewer calories and nutrients from the food you’ve eaten.
Depending on the patient, the surgeon may perform SADI as one procedure or as two separate procedures.
