Revision of Roux-en-Y Gastric Bypass for Inadequate Weight Loss or Weight Regain

Andreas Alexandrou et al. In Vivo. 2022 Jan-Feb.

Abstract

Inadequate weight loss or weight regain after Roux-en-Y gastric bypass (RYGBP) occurs in more than a quarter of patients for various reasons. Available remedying treatment options include endoscopic and surgical techniques for revision of the gastric pouch and the gastro-jejunal anastomosis, conversion of standard to distal gastric bypass (DRYGBP) or the conversion of RYGBP to biliopancreatic diversion (BPD) or duodenal switch (DS). There is quite a variability concerning the technical simplicity, safety, and effectiveness of these techniques and the small number of patients in the numerous single-center reports precludes any meaningful comparisons. This review aimed to describe all available methods and present the advantages and disadvantages of each of them, to facilitate, rather than guide, the decision of the average bariatric surgeon who encounters such a patient.

Keywords: Obesity; gastric bypass; outcomes; review; revisional surgery; weight regain.
