This surgery is also known as biliopancreatic deviation (BDP).
The basic principles of this procedure are almost the same as the Roux in “Y” gastric bypass, but in this procedure approximately an 80% of the stomach is resected. The pyloric valve, which controls the flow of the food from the stomach to the intestine, is one of the parts of the stomach that is not affected by the surgery.
A small portion of the small intestine, the duodenum, which is normally connected to the stomach, is not affected by this procedure. The intestine is almost completely bypassed when the connection to the last part of the intestine is done.
Malnutrition is one of the risks of this surgery, because of this and the higher risks and complications of this surgery we limit this procedure for special patients with Supermorbid extreme Obesity with a BMI higher than 50 with a clear indication for this surgery and as a two stage procedure.
