Usefulness of a clutch cutter for surgeons with experience of performing colorectal endoscopic submucosal dissection in less than 100 patients at an institution without tutors

Aims The usefulness of a clutch cutter (CC), a scissor-type knife, for colorectal endoscopic submucosal dissection (CESD) has recently been reported. However, there has been no study on the usefulness of a CC for surgeons with experience of performing CESD in less than 100 patients at an institution without tutors. Therefore, the usefulness of a CC for such surgeons was examined in the present study.
