Endoscopic submucosal dissection (ESD) has become a widely used endoscopic technique for the treatment of earlycolorectal tumors due to the advantages of high complete resection rate, low recurrence rate, small restriction, minimal trauma, and rapid recovery. However, because the difficult and long operation of ESD, as well as the thin colorectal wall, large bending angle, narrowlumen and folds, the perforation rate of colorectal ESD is relatively high. Therefore, proper understanding and knowledge of the occurrence, risk factors, prevention and management measures of colorectal ESD complicating perforation are essential for the successfulcompletion and clinical promotion of colorectal ESD. |
