Biliopancreatic Diversion

Biliopancreatic Diversion is both a restrictive and malaborptive procedure that works by altering the normal process of digestion, removing 2/3 of the stomach and rerouting food to pass by a section of the small intestine, thus limiting the amount of calorie absorption. Patients undergoing biliopancreatic diversion will feel full faster than before the surgery, which in turn cuts back the amount of food (and calories) consumed which is what leads to weight loss.

There are two versions of this surgery: Biliopancreatic diversion and a biliopancreatic diversion with duodenal switch. The difference between the two is the following:

  • Biliopancreatic Diversion – Part of the stomach is surgically removed, and the remaining portion of the stomach is connected to the lower portion or the distal segment of the small intestine.
  • Biliopancreatic Diversion with Duodenal Switch – Again a portion of the stomach is removed, but it is smaller than in the surgery without duodenal switch. And 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.
