Current status of colorectal endoscopic submucosal dissection in Korea

Colorectal endoscopic submucosal dissection (ESD) is not yet fully popularized in Korea, but is increasing steadily. The outcomes of colorectal ESD in Korea are comparable to those in Japan and other countries. ESD-related complication rates are decreasing as experiences accumulate. Particularly for rectal laterally spreading tumors, ESD is becoming more prevalent than transanal endoscopic microsurgery. Standard indication, qualified training system, and full medical insurance coverage should be established for the procedure to become popular in the long run.
