Global Technical Diversity in Roux-en-Y Gastric Bypass: An International Survey Among IFSO Members

Roux-en-Y gastric bypass (RYGB) is one of the most effective bariatric procedures worldwide, providing both restrictive and malabsorptive benefits. However, marked heterogeneity exists globally in pouch construction, limb configuration, mesenteric defect closure, and adjunctive practices, leading to difficulties in comparing outcomes across centers. Understanding these variations is essential for developing international consensus and standardized reporting.
