Perioperative Interventions to Prevent Gastroesophageal Reflux Disease and Marginal Ulcers After Bariatric Surgery - an International Experts' Survey

Sonja Chiappetta et al. Obes Surg. 2023 May.

Abstract

Objective: This study aimed to survey international experts in metabolic and bariatric surgery (MBS) to improve and consolidate perioperative interventions to prevent gastroesophageal reflux disease (GERD) and marginal ulcers (MU) after MBS.

Background: Very important long-term complications after MBS include GERD, Barrett's esophagus, and MU. Prevention might be fundamental to reduce the incidence, severe complications, and the increasing number of revisional bariatric surgeries.

Methods: An international scientific team designed an online confidential questionnaire with 45 multiple-choice questions. The survey was sent to 110 invited experts and 96 of them (from 41 different countries) participated from 21 July 2022 to 4 September 2022.

Results: Most experts (≥ 90%) prescribe postoperative acid suppression agents after MBS. Life-long proton pump inhibitors prophylaxis in smokers with avoidance of non-steroidal anti-inflammatory drugs are recommended by most of the experts (66%, 73%) after any type of gastric bypass. Two-thirds of experts (69%) perform Helicobacter pylori eradication prior to MBS. Two-thirds of experts (68%) routinely perform EGD and biopsy before MBS. Follow-up esophagogastroduodenoscopy (EGD) and timing threshold for revisional and conversional MBS were variable among experts.

Conclusion: This expert survey underlines important perioperative interventions that reached a two-thirds consensus among MBS international experts. Variability in follow-up EGD, approach to complication management, and thresholds for revisional and conversional MBS emphasize the need for further researches and consensus guidelines.
