NCT ID NCT04834635

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested a new surgical technique called FundoRing, where the surgeon wraps the unused part of the stomach around the new stomach pouch during gastric bypass. The goal is to improve weight loss and reduce bile reflux compared to the standard bypass. One thousand adults with obesity were randomly assigned to get either the FundoRing or standard surgery, and researchers tracked their weight, reflux symptoms, and complications over time.
