Endorotor versus standard endoscopic removal for walled-off pancreatic necrosis

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

NA · Assistance Publique - Hôpitaux de Paris · NCT07253350

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.

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.

Who should consider this trial

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.

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.

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 performed: 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.
