Biliopancreatic Diversion Bypass
The Biliopancreatic Diversion Bypass is an open surgery and requires a long incision that
will leave scarring. This surgery is not as common compare to Roux-en-Y gastric bypass and has undoubtedly more
side effects and complications. It is quite often patients that have had this surgery will experience loss of
nutrition, which may eventually cause long term health problems.
During this surgery, portions of the stomach are removed and the bypass is then attached to the distal illium
(part of the digestive tract). The small pouch that is created then serves as the stomach to hold food.
Both of the roux en Y and biliopancreatic diversion gastric bypass surgeries are designed to curb food
intake, thus allowing a person to take in fewer calories and lose weight faster. This bypass reduces the length of
functioning small intestine (where most nutritional uptake occurs) so that a significant amount of fat and other
macronutrients pass through undigested through the digestive system. A bypass is formed through surgery in the
small intestines to decrease the absorption of food. This will help curb hunger too.
Typically with bypass surgery, about half of the weight is lost within the first year and most patients reach
their weight loss goal within the second year after surgery. Although a more drastic procedure than other bypass
surgeries, biliopancreatic diversion bypass is particularly useful and effective for weight reduction.
