“…After a lapse of 10 years, endoscopic devices and related medical equipment have been developed with further refinements in the procedural techniques, which have led to a higher rate of resectability and lower rate of complications, as well as technical stabilization of gastric ESD. In particular, control of intraoperative bleeding is critical to a successful outcome of ESD; therefore, it has been estimated that improving the management of intraoperative bleeding by various advances in endoscopic devices and medical equipment, together with procedural refinements has enabled complete and safe resection (20,21). Furthermore, post-ESD preventive coagulation of visible vessels in the resection area of ESD, which was introduced in 2003, may have resulted in the lower rate of delayed bleeding observed in the last period (16).…”
