Duodenal Switch With Biliopancreatic Diversion

Duodenal switch with biliopancreatic diversion is an advanced technique in bariatric surgery to achieve weight loss.

During the initial consultation, the surgeon will determine the patient’s candidacy for duodenal switch surgery. Focused bariatric surgeon Dr. Wiljon Beltre provides weight loss procedures to patients in Orlando, Tampa, Maitland, Central Florida, and surrounding locations in the marvelous Sunshine State.

How does it Work?

The biliopancreatic diversion with duodenal switch comprises of two components. Initially, a small, tube-like stomach pouch is produced by removing a portion of the stomach. After that, the surgeon bypasses a significant portion of the small intestine.

A biliopancreatic diversion alters the regular process of digestion by decreasing the size of the stomach. It enables the food to bypass a portion of the small intestine so that the patient absorbs a lesser number of calories.

After the biliopancreatic diversion bariatric surgery, the patient feels fuller faster than when the stomach was it’s standard size. This significantly decreases the quantity of food that the patient desires to eat. Bypassing a part of the small intestine also leads to the absorption of lesser calories.

This facilitates in weight reduction. However, the patient will need to adopt a healthy lifestyle and eating habits to ensure that the weight loss outcomes are permanent.  

Types of Biliopancreatic Diversion

There are two types of biliopancreatic diversion procedures, namely, a biliopancreatic diversion and a biliopancreatic diversion with duodenal switch. A majority of surgeons avoid the biliopancreatic diversion with duodenal switch surgery if the patient does not have a BMI higher than 50 or the excess weight is not contributing to significant health issues.

A portion of the stomach is taken out in the biliopancreatic diversion surgery. The remaining portion of the stomach is linked to the bottom part of the small intestine. This procedure is high-risk and causes health challenges in the long-term. After the procedure, the body faces difficulties in absorbing nutrients and food.

In a biliopancreatic diversion with duodenal switch, a distinct portion of the stomach is removed. The surgeon ensures that the pylorus is left intact. The pylorus refers to the valve that controls the flow of food from the stomach to the small intestine.

Both these surgeries require a large incision in the belly during an open procedure. In the laparoscopic technique, several small incisions are placed, and small instruments and a camera are utilized to conduct the surgery.

What to Expect After the Procedure?

The surgery reduces the size of the stomach, and this causes the patient to feel fuller sooner. Food can also be released into the small intestine more rapidly. This is known as the “dumping syndrome.” A duodenal switch decreases the likelihood of the dumping syndrome.
