Preliminary report of a new scissor-like device for endoscopic submucosal dissection (ESD) for safe and effective treatment of Zenker's diverticulum

Introduction: Endoscopic therapy of Zenker's diverticulum is based on cutting the septum between the diverticulum and the esophageal lumen by using lasers, staplers, harmonic scalpels, argon plasma coagulation, or needle knives. Most recently, a new scissor-like device with serrated jaws for endoscopic submucosal dissection (ESD) was introduced. The device is fully rotatable and available in different lengths. In addition, the outer edges are insulated to minimize the risk of damaging tissue. Aims: First study to prospectively assess the potential of the new scissor-like ESD device for treatment of Zenker's dive…
