Fundoplication of the excluded stomach after one‑anastomosis (omega) gastric bypass

Official title: Evaluation of Post-Omega Bypass Excluded Stomach Fundoplication to Treat Disabling Gastroesophageal Reflux Disease Resistant to Medical Treatment and Requiring Surgery

Run by GCS Ramsay Santé pour l'Enseignement et la Recherche · NCT06621979 · Data updated 2026-11-12

This will try fundoplication of the excluded stomach to stop severe reflux in adults who had a one‑anastomosis (omega) gastric bypass and did not get relief from medicines.

Is this trial a fit for you?

Likely a good fit

Adults (≥18) who had a one‑anastomosis gastric bypass, have disabling reflux refractory to medical treatment, underwent fundoplication of the excluded stomach within the prior two years, and have preoperative objective reflux testing are the intended candidates.

Probably not a fit

Patients converted from one‑anastomosis to Roux‑en‑Y, those without objective evidence of reflux, those who respond to medical therapy, or patients with other non‑reflux causes of symptoms are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-center, ambispective, interventional, non-randomized pilot tests whether fundoplication of the excluded stomach can objectively suppress disabling gastroesophageal reflux after one‑anastomosis gastric bypass. Adults who underwent the bypass and then received the excluded‑stomach fundoplication within two years because medical therapy failed are eligible. The protocol uses comprehensive objective evaluations such as endoscopy, pH‑impedance monitoring, and imaging to measure reflux before and after the procedure. Outcomes include objective reflux control and patient-reported quality of life measures.

Why it matters

Potential benefit: If successful, this procedure could markedly reduce or eliminate disabling reflux symptoms and lower the need for further complex revision surgeries, improving patients' quality of life.

How similar studies have gone: This application of excluded‑stomach fundoplication after omega bypass is relatively novel and supported mainly by small case series with mixed preliminary results.
