Global Variations in Practices Concerning Roux-en-Y Gastric Bypass—an Online Survey of 651 Bariatric and Metabolic Surgeons with Cumulative Experience of 158,335 Procedures

Abstract

Introduction

There is significant variation in practices concerning Roux-en-Y gastric bypass (RYGB) among bariatric surgeons, but there is currently a lack of robust data on the nature and extent of these variations. The purpose of this study was to understand global variations in practices concerning RYGB.

Methods

A questionnaire-based survey on Survey Monkey® was created, and the link was shared freely on various social media platforms. The link was also distributed through a personnel email network of authors.

Results

A total of 657 surgeons from 65 countries completed the survey. Crohn’s disease and liver cirrhosis were considered absolute contraindications for RYGB by 427 surgeons (64.98%) and 347 surgeons (53.30%), respectively. More than 68.5% of surgeons performed routine upper GI endoscopy while 64.17% performed routine ultrasound of abdomen preoperatively. The majority of surgeons (77.70%) used the perigastric technique for Gastric pouch creation. Approximately, 79.5% used orogastric bougie. More than 70% of the respondents did not use any staple line reinforcement routinely. Only 17.67% of surgeons measured the whole small bowel length, and the majority of surgeons (86.5%) used constant length of BP limb. Approximately, 89% used constant length of alimentary limb. Approximately, 95% of surgeons preferred antecolic bypass, and more than 86% routinely closed the Petersen defect. Marginal ulcer prophylaxis was used by the majority (91.17%). Almost 95% of surgeons recommended lifelong vitamin and mineral supplements.

Conclusion

This survey identifies global variations in practices concerning RYGB. It identifies several areas for future research and consensus building.
