Should Surveillance Endoscopy Be Routine After One Anastomosis Gastric Bypass to Detect Marginal Ulcers: Initial Outcomes in a Tertiary Referral Centre.

Purpose: Encouraged by the excellent outcomes of one anastomosis gastric bypass (OAGB) reported by many authors, we added this procedure to our bariatric armamentarium in 2015. Here we present our initial experience of 68 cases and findings from routine upper gastrointestinal endoscopy at 1 year.

Materials And Methods: This is a retrospective analysis of a prospectively maintained database of a single surgical unit in a tertiary referral centre.
