The Duodenal Switch Process

Duodenal switch bariatricsThe duodenal switch is a weight-loss operation that modifies your stomach and your small intestine. It combines a gastrectomy (removal of part of your stomach) with an intestinal bypass, which makes the path your food takes through your intestines shorter.

 

In some extremely overweight patients this operation is performed in 2 stages: sleeve gastrectomy is performed first, followed 9-12 months later by the intestinal bypass portion of the procedure. It may also be used as a revision operation for sleeve patients who have not lost enough weight or who regain significant weight. In such cases the intestinal bypass is added beyond the sleeve rather than dividing the sleeve and converting it to a gastric bypass.

 

 

Expected Weight Loss

 

Most patients can expect to lose 60 to 80 percent of their excess body weight over a 2-year period. Clinical trials have demonstrated durable weight loss of about 70% of excess body weight beyond 10 years.
