HISTOLOGICAL PREPARATION OF SPECIMENS RESECTED BY ENDOSCOPIC SUBMUCOSAL DISSECTION

Abstract

Large lesions can be resected by endoscopic submucosal dissection (ESD) and diagnosed by pathological examination. However, when the resected specimens are handled improperly, it is impossible to make a correct diagnosis even if the specimen was obtained by en bloc resection. Endoscopists need to know how to handle the endoscopically resected specimens appropriately. The task of the endoscopist is not only ESD but also verification between endoscopic findings and pathological findings. This verification is needed to improve endoscopic diagnosis.
