Understanding Laparoscopic Duodenal Switch

Laparoscopic Duodenal Switch (BPDDS or DS) is a complex weight loss surgery that involves multiple elements. The first is removal of a large part of the stomach, which promotes weight loss because you become full after just a small amount of food. The second element reroutes the food, bypassing the small intestine where digestion normally occurs. The procedure also alters the way bile and digestive juices break down food. This promotes weight loss by reducing the number of calories that can be absorbed.


Combining laparoscopic bypass of a portion of the intestine with a laparoscopic sleeve gastrectomy, DS surgery represents a powerful combination of “malbabsorptive” and “restrictive” weight loss. The result is the best and most durable weight loss of any of the major bariatric procedures.


Because the process involves malabsorption, there are possible complications related to insufficient vitamin and mineral intake and absorption, but these are usually controllable with oral supplementation. With proper maintenance and follow-up, the Duodenal Switch is a safe and very effective bariatric operation.
