Repairing the esophagus during weight loss surgery for patients with a weak valve

Official title: A Randomized Controlled Trial Evaluating PAtients With Lax Gastroesophageal Junction to Initial Sleeve Gastrectomy With or Without Concomitant Crural Repair (REPAIR)

Run by Sengkang General Hospital · NCT05330910 · Data updated 2026-11-12

This study tests if fixing a hiatal hernia during weight loss surgery can help people with a weak valve have fewer problems like acid reflux and esophagus damage after their surgery.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 21-65 with a Hill's grade III gastroesophageal junction who are planning to undergo laparoscopic sleeve gastrectomy.

Probably not a fit

Patients with documented erosive esophagitis or those with Hill's grade I, II, or IV gastroesophageal junction will not benefit from this study.

What this trial studies

This clinical trial investigates the effects of repairing a hiatal hernia during laparoscopic sleeve gastrectomy (LSG) on the incidence of postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). The study aims to determine if patients with a lax gastroesophageal junction and hiatal hernia experience fewer complications after surgery when the hernia is repaired simultaneously. Participants will be divided into two groups: one receiving LSG alone and the other receiving LSG with hiatal hernia repair. The trial seeks to provide insights into the best surgical approach for patients at risk of postoperative complications.

Why it matters

Potential benefit: If successful, this approach could reduce the risk of postoperative GERD and EE in patients undergoing bariatric surgery.

How similar studies have gone: Previous studies have shown mixed results regarding the benefits of hiatal hernia repair during LSG, indicating that this approach is still under investigation.
