Laparoscopic Duodenal Switch

Laparoscopic Duodenal Switch

The duodenal switch (DS) is a modification of the BPD designed to prevent ulcers, increase the amount of gastric restriction, minimize the incidence of dumping syndrome, and reduce the severity of protein-calorie malnutrition. However, the dumping syndrome is also believed by many to be a benefit, rather than a detriment, in that it helps patients avoid eating sugary and high fat foods which would adversely affect weight loss. The DS was first reported by Dr Doug Hess in 1986.

These procedures have some of the highest reported weight loss in long-term studies, but also have the highest rate of nutritional complications compared to the Gastric Bypass and the purely restrictive procedures. These operations are some of the most complex in bariatric surgery.
