摘要

Background

The Roux-en-Y gastric bypass (RYGB) is regarded as one of the most effective treatments for obesity. The ring-augmented RYGB (raRYGB), has demonstrated superior long-term weight loss outcomes and better weight maintenance compared to the standard RYGB. There is no agreement regarding the optimal procedure for patients with a BMI >50 kg/m2. This study aims to evaluate the effectiveness and safety of ring augmentation of a RYGB with a MiniMizer ring in patients with a BMI >50 kg/m2 at 2-year follow-up.

Methods

This study is a retrospective cohort study performed at the Zuyderland Medical Center in Heerlen and the Nederlandse Obesitas Kliniek Zuid. All patients with a BMI >50 kg/m2 who underwent a raRYGB with a MiniMizer ring in the period 2016–2021 are included. Total weight loss (TWL), obesity-related complications, and surgical-related complications were analyzed over 2 years post-operative.

Results

A total of 171 patients were included, of whom 78.4% were female, with a median BMI of 54.0 kg/m2 (51.4–57.7 IQR) and age of 42 (32–52 IQR) years at baseline. The mean % TWL was 15.6 at 3 months, 24.8 at 6 months, 32.1 at 1 year, and 35.2 at 2 years post-operatively. Complications of Clavien Dindo 3 or higher within the first 30 post-operative days were seen in 8 patients (4.7%) of which 1 (0.6%) was ring related.

Conclusions

The raRYGB with a MiniMizer ring in this study population results in high total weight loss results after 2 years. Ring-related complications rates are low. Therefore, we conclude that a raRYGB is an effective and safe treatment option for patients with a BMI >50 kg/m2.
