BPD-DS Surgery: Understanding the Biliopancreatic Diversion with Duodenal Switch

Biliopancreatic diversion with a duodenal switch (BPD-DS) is an advanced form of weight loss surgery. Patients interested in BPD-DS may benefit from some basic information on the details of this procedure.

The Facts

• According to the National Institute of Diabetes and Digestive and Kidney Diseases, BPD-DS surgery aims to limit food intake through removal of a large section of the stomach and a reduction of the body's ability to absorb food calories.

Vertical Sleeve Gastrectomy

• BPD-DS surgery begins with a preliminary procedure called a vertical sleeve gastrectomy (VSG). During a VSG, surgeons cut the stomach down to a narrowed sleeve, which remains attached to a segment of the small intestine.

Stomach Reattachment

• The next step of BPD-DS involves a reattachment of the narrowed stomach to a much lower segment of the small intestine. This reattachment significantly decreases the body's ability to absorb calories and nutrients, according to Rochester General Hospital.

Surgery Options

• BPD-DS surgery may be performed as a traditional open-incision procedure or a minimally invasive procedure called a laparoscopy.

Considerations

• Potential complications of BPD-DS include frequent and liquid bowel movements, abdominal bloating, protein malnutrition, bone disease, anemia and increased risk of gallstones. In a small number of cases, reports Rochester General Hospital, death may also occur.
