| [ Summary ] |
Endoscopic piecemeal mucosal resection (EPMR) for large colorectal tumors, such as LSTs, is a useful form of curative EMR. This is especially so with type V pit patterns where magnification enables us to easily recognize the cancerous area in large adenomatous LST-granular type conditions. With this information, EPMR may be performed to avoid cutting these areas. To reduce the number of residual tumors and local recurrence after EPMR, it is important to observe the margin of the ulcer by using magnifying endoscopy.If tumor pits are still observed in the lateral margin, trimming must be performed on the lesions with argon plasma coagulation, or other means. |
