ABSTRACT

BACKGROUND AND AIMS: EUS-guided drainage and, if required, endoscopic necrosectomy (EN) has become gold standard for treatment of pancreatic walled-off necrosis (WON). A dedicated powered endoscopic debridement system, EndoRotor (Interscope Inc., Northbridge, MA, USA), has been introduced as an alternative to snare necrosectomy. This study evaluates the novel EndoRotor catheter, NecroMax 6.0, for EN in patients with WON.

METHODS: This single-center retrospective case series included consecutive WON patients treated with the NecroMax 6.0 catheter. Safety, ability to perform EN, and clinical resolution were evaluated.

RESULTS: Twenty patients underwent a total of 30 EN procedures with the NecroMax 6.0 catheter. One suspected device-related adverse event was observed (3.3%). In one procedure EN could not be performed due to excessive bending of the endoscope. Eighteen (90.0%) patients achieved clinical resolution.

CONCLUSION: Endoscopic necrosectomy with the NecroMax 6.0 catheter was technically feasible in 96.7% with a low rate of adverse events.
