In this article, we are going to discuss about a procedure known as Duodenal switch or biliarypancreatic diversion. This procedure has both the malabsorption as well as the restrictive properties. It can be easily said that this procedure is a step ahead from the gastric bypass surgery. A great deal of weight is lost through this procedure.

Let us see what this surgery is. Biliarypancreatic diversion or duodenal switch requires removal of the part of stomach and then the stomach is joined to the intestine. The second part of the operation is to divert the biliary and pancreatic duct openings into another part of the intestine. This surgery functions to create various channels. First channel serves as the passage of food. The second channel is where the biliary and the pancreatic ducts open. The third channel is where the food passage and the ducts meet.

Removing the part of stomach serves as restricting the amount of food intake. Creating the second channel of biliarypancreatic diversion allows delayed action of biliary and pancreatic enzymes on food that causes decreased absorption. So, this surgery also has the malabsorptive properties.

This weight loss surgery results in rapid weight loss, which can result in formation of gallstones. Therefore, in order to prevent this condition, the gallbladder is removed during this procedure.

It is important for individuals undergoing this type of weight loss surgery to follow the recommendations of their surgeon very closely.
