Duodenal Switch

The duodenal switch procedure is a combined malabsorptive and restrictive weight loss surgery. This procedure is also known as a vertical gastrectomy with duodenal switch, biliopancreatic diversion with duodenal switch and simply DS or BPD-DS. This method decreases the quantity of food your stomach can hold; thereby, the numbers of calories that can be absorbed and used are reduced.

During the procedure your bariatric surgeon creates a moderately sized stomach pouch by bypassing part of the small intestine, allowing you to lose weight without having to alter your eating habits. After the procedure, your stomach can only approximately five to six ounces of food, while other obesity procedures allow for one-half to one full ounce of food.

How Many People Have The Duodenal Switch Procedure?

Approximately, 20,000 duodenal switch procedures are performed annually in the United States.

The Duodenal Switch Procedure

The duodenal switch is one of the most complicated weight loss procedures performed. Performed either open or laparoscopically your bariatric surgeon combines two surgical techniques a restrictive component, which reduces the size of the stomach, and the malabsorptive component. This method rearranges the small intestine to separate the flow of the food from the flow of bile and pancreatic juices patients can lose 70-80% of excess weight within two years of the procedure.

During the procedure, your surgeon keeps a small part of the duodenum in the digestive system. The duodenum is the first section of the small intestine. It is located in the stomach and the jejunum, or the middle part of the small intestine. Then your surgeon rearranges the small intestine to separate the flow of the food from the flow of bile and pancreatic juices. Food and digestive juices interact only in the last 18-24 inches of the intestines, allowing for malabsorption. The procedure itself lasts 3-4 hours. Some surgeons may perform it in two procedures. Following your procedure, you will consume less food than usual, but it is still more than with other weight loss surgeries.
