Remission of type 2 diabetes in patients undergoing biliointestinal bypass for morbid obesity: A new surgical treatment

Background Nutrient interaction with the mid-gut may play a role in improving type 2 diabetes mellitus (T2D) after bariatric surgery. However, Roux-en-Y gastric bypass, biliopancreatic diversion, and sleeve gastrectomy include diversion of food from the duodenum and/or partial gastrectomy.

A prospective evaluation of the role of BIBP in glycemic control has not been reported. Objectives Longitudinal evaluation of T2D after BIBP. Setting University hospitals in Europe and Canada. Method The effects of BIBP on metabolism and glycemia in 28 consecutive patients with T2D were evaluated over 2 years. Results Decreases (P
