Endoscopic Management of Weight Regain

Abstract

Roux-en-Y gastric bypass (RYGB) is a commonly performed bariatric surgical procedure. Weight regain is common and multifactorial, with dilation of the gastrojejunal anastomosis (GJA) and possibly enlargement of the gastric pouch contributing factors for weight recidivism. Technological advancement in the field of bariatric endoscopy has led to several innovative approaches to manage these anatomic changes. This chapter will focus on available devices and techniques and review existing data and safety considerations of each.
