A Ring‑augmented Roux‑en‑Y Gastric Bypass with MiniMizer Ring is Effective and Safe in Patients with a BMI > 50 kg/m2.

This Letter to the Editor evaluates Jense et al.'s (2025) study on MiniMizer ring-augmented Roux-en-Y gastric bypass (RYGB) for patients with BMI > 50 kg/m2. While the study demonstrates promising outcomes-35.2% total weight loss (TWL) at 2 years and 83.3% diabetes remission-several limitations warrant discussion. Key concerns include (1) the absence of stratified data on ring diameters (6.5-8.0 cm), which obscures optimal size selection for balancing efficacy and complication risks; (2) limited applicability to revisional surgery, a common need for super-obese patients; and (3) insufficient reporting of micronutrient deficiencies and quality-of-life impacts, critical for holistic patient care. Additionally, the lack of cost-effectiveness analysis leaves the MiniMizer ring's economic justification unclear. We commend the authors' rigorous methodology but propose future research to address these gaps through standardized ring sizing, inclusion of revisional cases, and comprehensive nutritional and economic evaluations. These refinements would enhance the evidence base for ring-augmented RYGB in high-risk populations.
