Early experience with use of an endoscopic hot scissor-type knife for myotomy during per-oral endoscopic myotomy procedure

摘要

Background and AimsCurrent devices used for per-oral endoscopic myotomy (POEM) function predominantly to either cut tissue or coagulate vessels. When bleeding vessels are encountered within the submucosa or muscle, dedicated coagulation grasping devices are often necessary. An endoscopic “hot” scissor-type knife is available that combines coagulation and cutting functions. Scissor-type knives may therefore be helpful during the POEM procedure.
