Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

The biliopancreatic diversion with duodenal switch has two components. The first is similar to the sleeve gastrectomy, where a portion of the stomach is removed to create a smaller, tube-shaped stomach pouch. The second component involves bypassing a large portion of the small intestine. Like gastric bypass surgery, BPD/DS reduces the amount of food the stomach can hold and limits the absorption of calories and nutrients in the small intestine.

BPD/DS can result in greater long-term weight loss than other bariatric procedures. Eventually, patients are able to eat near normal amounts of food. The absorption of fat is reduced by 70 percent or more, and gut hormones that control appetite are favorably affected. However, this procedure carries the highest risk for complications and mortality, as well as a greater potential to cause deficiencies in protein, vitamins, and minerals.
