Duodenal Switch

The Duodenal Switch (DS) procedure is both restrictive and malabsorptive. A simple way to think of the DS procedure is like a sleeve gastrectomy that also includes rerouting the intestines to further limit caloric intake.

The restrictive portion involves removing approximately 65%-75% of the stomach creating a cylindrical sleeve shaped stomach with a capacity of about 10-12 ounces. The intestine is then divided just past the gastric outlet (where food exits the stomach and enters the small intestine) and reconnected much further downstream creating 2 separate channels called the biliopancreatic channel (where bile and pancreatic juices flow) and the alimentary channel (which carries the food from your stomach). These 2 channels come together in the common channel where absorption of fat and calories occur.

Compared to the gastric bypass, this procedure has a longer area of intestine that is bypassed and a shorter common channel, therefore the DS procedure involves a greater amount of malabsorption than does the gastric bypass procedure. Patients who have had a duodenal switch procedure typically only absorb about 20% of the fat they intake. As with all the surgical weight loss procedures presented in this book, it is very important for DS patients to adhere to a lifelong vitamin and mineral regimen and undergo evaluation with yearly nutrition labs.
