| [ Summary ] | Colorectal ESD is difficult to treat compared to gastric ESD because of the thin colorectal wall and the presence of curves and folds. ESD is better than surgical treatment for superficial giant rectal cancer due to the ability to provide functional preservation. We stress the importance of dissection depth in providing safe ESD. Dissection levels must be carefully maintained between horizontal vascular networks in the submucosal layer and the muscularis propria. In this manner is possible to fully treat difficult cases such as those involving fibrotic lesions. It these ways it is possible to perform accurate pathological examinations of appropriate samples. | |
