Core Tip
Core tip: The clutch cutter (CC) was developed to reduce risk of complications related to endoscopic submucosal dissection (ESD) using conventional knives. The CC can grasp, pull, coagulate and/or incise targeted tissue using electrosurgical current, as with a bite biopsy. The CC can be used in all ESD steps (marking, mucosal incision, submucosal dissection, and hemostatic treatment). ESD using the CC (ESD-CC) for gastric adenoma (GA) gave a 100% R0 resection rate in this study, with no perforation. ESD-CC is a technically efficient, safe, and easy method for resecting GA.
