Weight Loss through Duodenal Switch or Biliopancreatic Diversion

Also known as Biliopancreatic Diversion, Duodenal Switch is a modern day weight loss surgery that is both, restrictive and malabsorptive.

Duodenal Switch involves removing approximately 70 percent of the stomach that comprises the area with a greater curvature, in the first step. In the second step, a long portion of the small intestine is re routed to create two different pathways and a single common channel.

The two pathways thus created are meant to perform separate functions. The shorter one, also known as the digestive loop takes food from the stomach to the common channel. The longer one, known as the biliopancreatic loop performs the function of carrying bile from the liver to the common channel. The common channel is usually 75 to 150 centimeters long and is a part of the intestine. In this channel the digestive path mixes with the bile from the biliopancreatic loop before losing it all in the large intestine.

This complete process reduces the amount of time taken by the body to absorb calories from food in the small intestine thereby limiting the absorption of fat. After the surgery has been done, as a result of this arrangement only 20 percent of the total fat gets absorbed.

Who all can go for Duodenal Switch and what are the risks involved?
Anybody with a Body Mass Index greater than 40 can go for this surgery. Also, those with BMI more than 35 accompanied by other ailments like sleep apnea or type2 diabetes are appropriate candidates for duodenal switch.

Long term risks may include hernia and bowel obstruction.
