Biliopancreatic Diversion with Duodenal Switch Gastric Bypass

The Biliopancreatic Diversion with Duodenal Switch (BPD/DS) is a 2-part procedure. First, a portion of the stomach is removed to create a smaller stomach pouch, similar to the sleeve gastrectomy procedure. Then, the bottom part of the small intestine is brought up and connected to the new stomach pouch, bypassing a large portion of the small intestine.

Like other weight loss surgeries, BPD/DS initially helps to reduce the amount of food that can be consumed. This effect decreases over time, and patients of this procedure are eventually able to eat almost “normal” amounts of food. Unlike other procedures, BPD/DS bypasses a large part of the small intestine. This process causes a significant decrease in the absorption of calories and nutrients.

How Effective Is BPD/DS?

In terms of weight loss, the large majority of patients will lose up to 70% of their excess body weight after one year. BPD/DS is also considered highly effective for treating type 2 diabetes.

Is BPD/DS Reversible?

No. BPD/DS should be considered permanent.
