Abstract
The current indications for colorectal endoscopic submucosal dissection (ESD) are large colorectal cancers (CRC) or adenomas in which conventional en bloc endoscopic mucosal resection (EMR) is predicted to be difficult. However, because early CRC with submucosal (SM) deep invasion should not be treated with ESD due to increased lymph node metastasis risk, it is important to accurately diagnose invasion depth before treatment. Based on previous clinicopathological analyses, Based on previous clinicopathological analyses, laterally spreading tumor (LST) non-granular types > 20mm are definite candidates for ESD and LST granular types > 30mm are possible candidates for ESD.
