Biliopancreatic Diversion (BPD) and Bandinaro are more complex procedures for certain patients with specific medical and weight loss requirements.

BPD is a type of gastric bypass to treat severe clinical obesity. Biliopancreatic Diversion combines a certain amount of restriction with a high degree of malabsorption, and was originally designed to reduce the health complications associated with the discontinued jejuno-ileal bypass procedure.

BPD changes the normal process of digestion by making the stomach smaller and allowing food to bypass part of the small intestine so that you absorb fewer calories. You will feel full more quickly than when your stomach was its original size, which reduces the amount of food you eat and thus the calories consumed. Bypassing part of the intestine also means that you will absorb fewer calories. This leads to weight loss.

Although it produces excellent weight loss results, and permits patients to eat a larger amount of food than after most bypass operations, BPD is less common nowadays because BPD patients require long-term nutritional follow-up to prevent post-operative malnutrition
There are two biliopancreatic diversion surgeries: a biliopancreatic diversion and a biliopancreatic diversion with duodenal switch.
  • In a biliopancreatic diversion, a portion of the stomach is removed. The remaining portion of the stomach is connected to the lower portion of the small intestine.
  • In a biliopancreatic diversion with duodenal switch, a smaller portion of the stomach is removed, but the remaining stomach remains attached to the duodenum (the upper part of the small intestine). The duodenum is connected to the lower part of the small intestine.
These procedures can be done by making a large incision in the abdomen (an open procedure) or by making a small incision and using small instruments and a camera to guide the surgery (laparoscopic approach).
