Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy for treating morbid obesity

The procedure

Single-anastomosis duodeno-ileal bypass with sleeve gastrectomy for treating morbid obesity is usually done under a general anaesthetic by keyhole (laparoscopic) surgery. It involves 2 steps. First, a gastric sleeve is made by removing some of the stomach to make it smaller and into a tube shape. Then, the first part of the small intestine is shortened and joined to the last part of the small intestine. The procedure is permanent. Sometimes, the steps are done in 2 separate operations. The aim is to reduce the size of the stomach and small intestine to reduce the amount of food that is absorbed into the body.

After surgery, patients have to eat a low-calorie diet. Multivitamins, calcium and iron supplements are prescribed when needed.
