Biliopancreatic Diversion with Duodenal Switch
The Biliopancreatic Diversion with Duodenal Switch is a two-part bariatric procedure wherein the surgeon would first create a tubular pouch in the stomach by removing a part of the stomach – as in case of a gastric sleeve and secondly, a bypass is made in the large intestine. This procedure helps reduce the amount of food intake and thereby assists weight loss over a period of time.
However, in some of the other procedures the affect of the reduced stomach wanes over a period of time and thereby the patient by return to normal consumption of food over a period of time. Thus, in case of BD/DS, this is addressed by bypassing a large part of the small intestine, also the food consumed does not mix with the pancreatic and/bile enzymes until it is considerably down in the lower intestine leading to much lower quantities of absorption of nutrients into the blood stream.
This procedure is known to result in about 60-70% weight loss with a reduction in fat of 70% or more. It is also helpful in mitigating risks from type 2 diabetes, heart conditions, hypertension and other lifestyle/obesity related conditions.
However, on the disadvantages side, the procedure may require a slightly longer hospitalization compared to other bariatric procedures and has a statistically higher mortality rate when compared to the other bariatric surgeries.
