Biliopancreatic diversion – Duodenal switch
What is it?
BPD-DS is a well established weight loss surgery procedure in which approximately 50% of the stomach is removed and a significant amount of the small bowel is re-routed to increase malabsorption of calories. This operation is reserved for patients with BMIs greater that 50.
How does it work?
The reduction in size of the stomach by 50% results in restriction of food being taken in and the large part of the effect of the operation is caused by the shortening of the bowel involved in the absorption of calories. This leads to excellent durable weight loss in patients with BMIs over 50. The duodenum is one of the portions of small bowel bypassed and thus, BPD-DS is excellent for diabetes resolution. The feeling of hunger normally disappears for some time.
