Core Tip
Core tip: Many types of knives have been developed and used for endoscopic submucosal dissection (ESD). We modified the grasping type scissors forceps and developed a novel grasper type scissors (GTS). The aim of this study was to evaluate the efficacy and safety of GTS compared to hook knife plus coagrasper (HKC) for ESD of gastric epithelial neoplasia. The procedures were performed without interruption in every case in both groups. GTS is a safe and effective device for ESD of gastric epithelial neoplasia compared with HKC. ESD can be performed with GTS alone, which can reduce the costs for ESD.
