Abstract
Endoscopic mucosal resection (EMR) allows histopathological examination to be performed because specimens are collected as with surgical resection . It can also provide equivalent curability to surgical resection, depending on the patient . In recent years, the development of endoscopic submucosal dissection (ESD) has made it possible to resect large lesions and the surrounding normal tissues in an en bloc manner . Accordingly, it is necessary to properly handle the specimens obtained by EMR as with surgically resected specimens, and it is important to make an accurate histopathological diagnosis . For this purpose, it is important to assess complete resection correctly by handling EMR specimens according to a strict protocol and conducting stereoscopic microscopy.
