Is the duodenal switch the same surgery as the open/laproscopic bilio pancreatic diversion?

BPD is a more complex surgery than DS, and it is typically reserved for patients who are very obese or have other health conditions that make them high risk for other weight-loss surgeries.Duodenal Switch (DS)
DS is a combination of a restrictive and malabsorptive surgery. The first step of the surgery is to remove about 80% of the stomach. This reduces the amount of food that you can eat and helps you feel full sooner. The second step of the surgery is to bypass a large portion of the small intestine. This means that your body will not absorb as many calories and nutrients from the food that you eat.
Biliopancreatic Diversion (BPD)
BPD is a purely malabsorptive surgery. The stomach is not bypassed or removed, but a large portion of the small intestine is bypassed. This means that your body will not absorb as many calories and nutrients from the food that you eat. BPD is a more complex surgery than DS, and it carries a higher risk of complications.

There are a few terms used that mean almost the same thing. You will see terms like BPD (biliopancreatic diversion), duodenal switch and Scopinaro. They are similar procedures with slight variations. It also depends on who performs the surgery. But their basic principle remain the same.
