What is Biliopancreatic Diversion?

Biliopancreatic diversion is a type of obesity surgery, usually the most technically demanding procedure of all the weight loss surgeries. This surgery will change the normal digestion process, by making your stomach smaller and bypassing the food from a part of your small intestine. This will make you absorb only a few calories.

Types of Biliopancreatic Diversion Surgeries

Biliopancreatic Diversion:

In this procedure, a portion of your stomach will be removed. Remaining portion of your stomach will be connected to your small intestine’s lower portion.

Biliopancreatic Diversion With Duodenal Switch:

A smaller portion in your stomach will be removed and the remaining stomach will be left attached to the duodenum. Upper part of your small intestine is called duodenum

Both the procedures need either a large incision in your abdominal area (open procedure) or a small incision, and the surgery is done using small surgical instruments and a camera for guiding the process (laparoscopic approach). The stomach capacity will be 4 to 5 ounces, so you will not be able to consume anything more than that.

Benefits of Biliopancreatic Diversion
