Biliopancreatic Diversion Gastric Bypass
The bariatric stomach bypass procedure known as biliopancreatic diversion (Scopinaro procedure) is one of the more extreme malabsorptive surgeries used to treat clinical, morbid and malignant obesity. Not only is a large part of the stomach removed, but the anatomy of the small intestine is changed to divert the bile and pancreatic juices so they meet the ingested food (arriving via the reduced stomach pouch) closer to the middle or the end of the small intestine. As a result, calorie and nutrient absorption is severely curtailed.
Biliopancreatic Diversion Bypass Procedure
This is a longer, more complicated stomach bypass procedure. The bariatric surgeon removes roughly 3/4 of the stomach which restricts both food intake and stomach acid production. The small intestine is then divided, with one end attached to the stomach pouch thus forming the "alimentary limb." All food ingested into the stomach passes down this segment which completely bypasses the duodenum and the jejunum. Meanwhile, the digestive juices from the pancreas are channeled through the "biliopancreatic limb," which meets the "alimentary limb" thus forming a common limb at which point some calorie and nutritional absorption then occurs. Bariatric surgeons are able to vary the length of this common digestive tract to regulate the degree of absorption of protein, fat and fat-soluble vitamins.
Weight Loss After Biliopancreatic Stomach Bypass
On average, patients who have malabsorptive bypass surgery, like biliopancreatic diversion, typically lose two-thirds of their pre-operative excess weight within 2 years. Although a more drastic procedure than other bypass surgeries, biliopancreatic bypass is especially effective for weight reduction.
Eating Guidelines After Biliopancreatic Diversion Surgery
After undergoing stomach by-pass surgery, patients should eat small meals frequently throughout the day, as their new smaller stomach cannot accommodate large meals. Neither can the new stomach tolerate large amounts of fat, alcohol, or sugar. So for optimum weight loss and minimum side effects after biliopancreatic diversion surgery, it is essential that patients reduce fat intake, especially fast food meals and deep-fried foods, as well as high-sugar foods like cakes, cookies, and candy.
