Duodenal Switch

The Duodenal Switch forms a tube-shaped stomach pouch, similar to a sleeve gastrectomy, and reduces the use of the small intestine, resembling a gastric bypass.

The Procedure

After forming the sleeve-like stomach, the first portion of the small intestine is detached. Then, a section of the small intestine is connected to the new stomach outlet, allowing food to pass from the sleeve pouch to the lower part of the small intestine.

How it Works

The smaller stomach limits food intake, while bypassing about 75% of the small intestine, more than any other common procedure, significantly reducing calorie and nutrient absorption.

Patients need vitamin and mineral supplements post-surgery. The duodenal switch alters intestinal hormones to reduce hunger, increase fullness and improve blood sugar control more than a gastric bypass or sleeve gastrectomy.

This makes it the most effective approved metabolic surgery for treating type 2 diabetes.
