What is Duodenal Switch Surgery?

Duodenal switch surgery is the most powerful of all the bariatric procedures. The duodenal switch procedure involves two steps.

Your surgeon will begin by performing a sleeve gastrectomy. In this step, the surgeon will remove around 80% of your stomach, leaving a tube-shaped piece about the size of a banana. Then, the first portion of the small intestine is detached from the rest of the small intestine. This will include the valve that releases food to the small intestine (the pyloric valve).

The surgeon will then connect the latter part of the small intestine to the stomach, bypassing the majority of the small intestine. Food will then enter the stomach pouch and pass through to the latter part of the small intestine.

A duodenal switch bariatric surgery encourages weight loss in two ways. First, it limits the amount of food you can eat by reducing your stomach size. Second, the intestinal bypass reduces nutrient absorption, including fats and proteins.

The two steps of the duodenal switch procedure are usually done at the same time. However, in some cases, your surgeon may recommend performing the sleeve gastrectomy first and then the intestinal bypass once weight loss has begun.
