Duodenal Switch

Duodenal switch surgery combines food intake restriction with reduced calorie absorption, resulting in higher weight loss. It also has a 98% “cure” rate for type 2 diabetes.

The procedure is quite complex and involves reducing the size of the stomach, removing the gallbladder and rerouting the intestines – 4 steps in all:


1. Around 70% of the left side of the stomach is removed creating a cylindrical-shaped pouch that connects the esophagus to the small intestine.

2. The top of the small intestine is then cut, leaving part of the duodenum (where most of the body’s chemical digestion takes place) attached to the stomach and removing the gallbladder.


3. Next, the lower part of the small intestine is cut approximately 1 meter from where it connects to the large intestine. The duodenum is then attached to the part that is still connected to the large intestine.


4. Finally, the end of the loose part of the small intestine is attached to the part of the small intestine that connects the duodenum to the large intestine. This lets the gastric juices mix with the food from the stomach in the last section of the small intestine.

This procedure may be performed as open surgery or laparoscopically. After surgery, patients will, need to take vitamin supplements for the rest of their lives.
