EUS-guided drainage and, if required, endoscopic necrosectomy (EN) has become the criterion standard for the treatment of pancreatic walled-off necrosis (WON). A dedicated powered endoscopic debridement system, the EndoRotor (Interscope Inc, Northbridge, Mass, USA), has been introduced as an alternative to snare necrosectomy. This study evaluates the novel EndoRotor catheter, NecroMax 6.0 (Interscope Inc, Whitinsville, Mass, USA), for EN in patients with WON.
This single-center retrospective case series included consecutive patients with WON treated with the NecroMax 6.0 catheter. Safety, ability to perform EN, and clinical resolution were evaluated.
Twenty patients underwent 30 EN procedures with the NecroMax 6.0 catheter. One suspected device-related adverse event was observed (3.3%). In 1 procedure, EN could not be performed because of excessive bending of the endoscope. Eighteen patients (90.0%) achieved clinical resolution.
EN with the NecroMax 6.0 catheter was technically feasible in 96.7% of patients with a low rate of adverse events.
超声内镜引导下引流术，如果需要，内镜下坏死组织清除术（EN）已成为治疗胰腺包裹性坏死（WON）的标准方法。一种专门的电动内镜清创系统，EndoRotor（Interscope Inc，Northbridge，Mass，USA），已被引入作为套扎坏死组织清除术的替代方法。本研究评估了新型 EndoRotor 导管，NecroMax 6.0（Interscope Inc，Whitinsville，Mass，USA），用于治疗 WON 患者的 EN。
这项单中心回顾性病例系列研究纳入了接受 NecroMax 6.0 导管治疗的连续 WON 患者。评估了安全性、EN 的实施能力以及临床缓解情况。
20 例患者接受了 30 次 NecroMax 6.0 导管的 EN 治疗。观察到 1 例疑似与器械相关的不良事件（3.3%）。在 1 例手术中，由于内镜过度弯曲，无法进行 EN。18 例患者（90.0%）实现了临床缓解。
在 96.7%的患者中，使用 NecroMax 6.0 导管进行 EN 是可行的，不良事件发生率低。
