The Duodenal Switch is a weight loss surgery that is both restrictive and malabsorptive. The Duodenal Switch is a laparoscopic or minimally invasive procedure. The surgeon works with instruments and a camera inserted through small incisions in the abdomen.
Duodenal Switch: How Does It Work?
The procedure starts the same as a Sleeve Gastrectomy by removing about 1/2 of the stomach which creates a small stomach pouch about the size of a banana. The first part of the small intestine is divided. The small intestine is measured from the colon backwards to limit absorption. This part of the small intestine is connected to the first part of the small intestine. A second intestinal connection is made to further limit absorption.
