biliopancreatic diversion

a surgical treatment for morbid obesity consisting of resection of the distal two thirds of the stomach and attachment of the ileum to the proximal stomach. The duodenum and jejunum are bypassed and empty their secretions into the distal ileum through a new anastomosis. Also called biliopancreatic bypass.

BPD

A bariatric surgical treatment for obesity in which most of the stomach is removed. The remaining proximal pouch is anastomosed to the distal ileum bypassing the duodenum and proximal small intestine. The proximal small intestinal segment is anastomosed to the ileum distal to the gastroileal anastomosis. The procedure restricts the intake of nutrients and causes malabsorption, both of which lead to weight loss. Successful procedures result in sustained weight loss of about 25% of body weight, a result as good as any other surgical treatment for overweight. Common complications of the procedure include iron-deficiency anemia, deficiencies in the absorption of vitamins A, D, E, and K and the minerals calcium and magnesium, gradual bone loss, foul-smelling stools, and failure of surgical anastomoses. The operation takes more time to perform than other bariatric surgeries and tends to have more immediate postoperative complications. The procedure is infrequently performed because of its many complications.

Bariatric surgery helps to accomplish continuous weight loss by either reducing the size of the stomach to reduce food intake with an implanted medical device (gastric band or intragastric balloon) or through removal of a portion of the stomach (sleeve gastrectomy) or by resecting and rerouting the small intestines to a small stomach pouch to reduce nutrient absorption (Roux-en-Y gastric bypass or biliopancreatic diversion with duodenal switch).
