Biliopancreatic Diversion with Duodenal Switch (BPD/PS)
BPD/PS is a kind of combination of two methods of weight loss surgery. Sleeve gastrectomy and gastric bypass. First, the specialist cut the stomach and reduce totally the sizes of the stomach (80% of the stomach is removed) but the pyloric valve and the duodenum remain. Next, the duodenum (a small part of the intestine near the stomach) is joined to end part of your intestine. Next action is bypass step. So it’s clear that BPD/PS reduces the amount of food you eat and reduce the absorption of that. Those two actions are performed simultaneously but you can choose to do that in a two-step. This complicated surgery can cause Malnutrition although it can be more effective. So specialists just prefer to do that for a patient with a BMI over 50.
