Summary

This is a national single-blinded prospective multicenter randomized (1:1) controlled trial, with two parallel arms, using a PROBE methodology, including patients with complicated acute necrotizing pancreatitis who require DEN of WON collection after endoscopic drainage. We will compare 2 groups: conventional DEN and DEN with Endorotor®. The study will be offered to all consecutive patients fulfilling the eligibility criteria after endoscopic drainage for WON. Since the time between drainage and the first necrosectomy session is usually at least 48 hours a period of at least 24h will be allowed for the patient to consider options to participate or not. Information and collection of informed consent will be done by an investigating physician.

Conditions

  • Acute Necrotizing Pancreatitis

Interventions

DEVICE

Endorotor Group

DEN will be performed with Endorotor 3.2 or ENDOROTOR PED® system depending on the position of cystoenterostomy. Endorotor 3.2 is slimmer and enters WON more easily when the transgastric access is located in the upper portion of the stomach). If needed: lavage, aspiration and conventional mechanical debridement could be used in addition during an ENDOROTOR-based DEN session.

OTHER

Conventional group

DEN is performed conventionally with abundant lavage and mechanical debridement using a non-dedicated material (diathermic loop, polypectomy or Dormia basket) to catch pieces of necrosis
