Run by Centre Hospitalier Departemental Vendee · NCT04994665 · Data updated 2026-11-12

This study is testing if adding a procedure called omentopexy during sleeve gastrectomy can help prevent new cases of acid reflux in patients after their surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with obesity-related comorbidities and a BMI between 35 and 40 kg/m² or a BMI of 40 kg/m² or higher.

Probably not a fit

Patients with eating disorders, mental disorders, or those with a BMI below 35 kg/m² are unlikely to benefit from this study.

What this trial studies

This study aims to assess the impact of omentopexy on the development of gastro-oesophageal reflux disease (GERD) following sleeve gastrectomy. It is a prospective, multicentric, randomized trial involving 526 patients, divided into two groups: one undergoing sleeve gastrectomy alone and the other undergoing sleeve gastrectomy with omentopexy. The evaluation will occur two years post-surgery, utilizing the CARLSSON and BAROS scores to measure quality of life and reflux rates. The primary goal is to demonstrate that omentopexy reduces the incidence of de novo GERD without relying on Proton-Pump Inhibitors.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of GERD in patients undergoing sleeve gastrectomy, improving their quality of life.

How similar studies have gone: While the specific approach of omentopexy in this context may be novel, similar studies have shown promising results in managing GERD post-bariatric surgery.
