Single Anastomosis Duodeno-Ileal Switch (SADIS)
SADI-S (Single anastomosis duodeno–ileal bypass with sleeve gastrectomy) is a newer variant of duodenal switch surgery, which for three decades has helped obese patients control their weight. The key benefit of SADI-S is that one intestinal bypass is made, rather than two, resulting in less time in surgery and reduced risk of intestinal leakage. SADI-S actually removes less of the intestine than other types of bariatric surgery, increasing the amount of nutrients your body will be able to absorb. You will need to take vitamins for the rest of your life, however. Because only one new intestinal connection is made in SADI-S, there is less risk of contents leaking from the intestine into the body cavity. This single connection also has the advantage of preventing the possibility of future bowel obstruction, also known as an internal hernia.
How It Works
The procedure involves a laparoscopic surgery to be performed in which a small gastric sleeve needs to be created by removing the greater part of the stomach, such as in the sleeve technique. This technique offers excellent weight loss and metabolic results.
Single Anastomosis Duodeno-ileal Switch reduces operative time and decreases the possibility of surgically related complications. Patients can get satisfactory results in weight loss after undergoing this surgery.
