Endorotor versus standard endoscopic removal for walled-off pancreatic necrosis
Official title: Effectiveness of Endorotor PED® System Versus Conventional Endoscopic Techniques for the Management of Walled-off Pancreatic Necrosis in Acute Necrotizing Pancreatitis: Randomized Single-blinded Controlled Superiority Trial and Cost-utility Analysis
Run by Assistance Publique - Hôpitaux de Paris · NCT07253350 · Data updated 2026-11-12
This trial will try whether using the Endorotor device helps adults with infected or symptomatic walled-off pancreatic necrosis recover faster or with fewer procedures than standard endoscopic necrosectomy after drainage.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18 years) hospitalized for acute necrotizing pancreatitis who have undergone endoscopic drainage for infected or symptomatic WON and still require at least one DEN session are ideal candidates.
✕Probably not a fit
Patients without an endoscopic drainage in place, those who already had a necrosectomy before screening, people with limited life expectancy, known major bleeding disorders, or who are pregnant will not benefit or are ineligible.

What this trial studies
This is a national, single-blinded, multicenter randomized (1:1) trial using a PROBE design that enrolls adults with complicated acute necrotizing pancreatitis who require direct endoscopic necrosectomy (DEN) after endoscopic drainage of walled-off necrosis (WON). Participants are randomized to conventional DEN or DEN using the Endorotor system, with outcomes including clinical recovery, number of necrosectomy sessions, complications, and cost-utility. Informed consent is obtained after at least 24 hours of consideration following a minimum 48-hour interval from drainage to the first necrosectomy session. The trial compares procedural effectiveness and resource use between the two approaches across participating French centers.
Why it matters
Potential benefit: If successful, the Endorotor approach could reduce the number of necrosectomy sessions, shorten hospital stays, lower complication rates, and decrease overall treatment costs.
How similar studies have gone: Small case series and nonrandomized reports of powered endoscopic necrosectomy devices have shown promising results, but randomized controlled evidence directly comparing Endorotor to conventional DEN is limited.
