Biliopancreatic Diversion with Duodenal Switch

This procedure is considered to be primarily a malabsorptive operation. It restricts both the amount of food that the body can intake, as well as the amount of calories and nutrients the body absorbs. During this procedure stapling is used to reduce the capacity of the stomach, while retaining the natural stomach outlet. The majority of the small intestine is bypassed, causing nearly complete malabsorption of food contents.

Unlike banding weight loss procedures, biliopancreatic diversion with duodenal switch involves the removal of about 70% of the stomach. While often considered one of the most difficult weight loss procedures, it produces the greatest amount of total excess body weight loss among currently performed operations.

The benefits of this medical weight loss procedure are many. Patients experience more rapid weight loss after undergoing surgery, less food intolerance, and greater long term weight loss. However, it does have potential shortcomings as well. Protein and vitamin malnutrition are possible concerns after this procedure.

Chronic diarrhea is another potential complication from this procedure. The most important factor in electing to have biliopancreatic diversion with duodenal switch is to ensure your bariatric surgeon is experienced, and properly trained in the procedure
