Brief Summary

Bilio-Pancreatic diversion with Duodenal Switch (BPD-DS) is the most effective bariatric procedure in terms of long-term weight loss and remission rate of Type 2 Diabetes. However, its technical difficulty and increased risk of long-term nutritional deficiencies have been a major hindrance to its diffusion. Recently, a " simplified " technique of Duodenal-Switch has been proposed by Sanchez-Pernaute et al. This technique involves the creation of a Sleeve Gastrectomy, transection of the first duodenum, and connection of the duodenum to an omega-loop of small bowel instead of a terminal intestinal loop used in standard BPD-DS. The overall objective of this study is to assess in a prospective randomized blinded trial, the outcomes of this new procedure, using a comprehensive clinical evaluation and follow-up method. This could potentially change the clinical practice and surgical approach in our Institution.
