Summary

The loop duodenal switch (L-DS) is a single-anastomosis biliopancreatic diversion with duodenal switch (BPD-DS) procedure. The original BPD-DS has two-anastomosis and is an accepted and approved bariatric procedure by the American Society of Metabolic and Bariatric Surgery. Preliminary data from Sanchez-Pernaute et al. (2013) indicates that the L-DS procedure is safer and easier to perform as it only requires one anastomosis compared to the BPD-DS, and offers good results for treatment of both morbid obesity and its metabolic comorbidities, including type-2 diabetes mellitus. However, the initial publications of the loop DS still resulted in a small number of patients with total protein malnutrition. For this reason, the investigators will study the loop DS with a modification of the originally published technique with a longer common channel limb (300 cm) to reduce the risk of protein malnutrition For patients with a BMI \>50, many are limited to just a sleeve gastrectomy as other bariatric procedures are technically challenging with increased operative risk. A loop duodenal switch may be a safer operation with improved weight loss for the super-morbidly obese patient.

PROCEDURE

Loop duodenal switch

The loop duodenal switch (L-DS) is a single anastomosis duodeno-intestinal bypass. In this simplified version of a BPD-DS, a sleeve gastrectomy is followed by a single anastomosis of the duodenum to the ileum in a loop fashion. The proposed benefits of this are to reproduce the excellent weight loss seen after a BPD-DS (an accepted and utilized bariatric procedure in the USA) but with the potential for reduced complications. With one anastomoses in the L-DS over two in the BPD-DS there is a theoretical lower probability of leaks, strictures, reduced anesthesia with shorter operative times, and decreased risk of internal hernia.
