Core Tip

Core tip: Although mechanical closures of larger artificial ulcer floor are effective to prevent post-endoscopic submucosal dissection (ESD) bleeding, mechanical closures might create a mucosal bridge which reduces the efficacy of prevention of post-ESD bleeding. Although covering with polyglycolic acid sheet (PGAs) is a more ideal treatment, it is difficult to deliver thin PGAs by pan-endoscope. Therefore, novel concept to deliver various devices and materials were developed.
