Endorotor-Based Endoscopic Necrosectomy as a Rescue or Primary Treatment of Complicated Walled-off Pancreatic Necrosis. A Case Series.

Direct endoscopic necrosectomy (DEN) is a cumbersome, time-consuming procedure that can be necessary in cases of infected pancreatic walled-off necrosis (WON) not responding to endoscopic ultrasound (EUS)- guided drainage only. Until now, DEN has been performed with non-dedicated devices, thus requiring multiple, long-lasting sessions to achieve adequate clearance of necrotic content. These results in prolonged hospital stay, increased costs and have potential consequences for patients who must undergo multiple endoscopic interventions under sedation. We report four cases of DEN performed in patients with WON after EUS-guided drainage with the Endorotor system, a new morcellator device specifically designed to perform the procedure.
