| [ Summary ] |
Among early colorectal carcinomas (Tis/T1), lesions with little possibility of lymph node metastasis and higher expectancy of curability with en bloc resection on the basis of the size and the location are usually treated endoscopically because such cases are expected to be curable. Obvious clinical T1b carcinomas (submucosal invasion depth ≥1,000μm) are usually treated surgically. When endoscopic treatment is carried out for colorectal carcinomas, en bloc resection is the principal approach ; however, piecemeal resection is also acceptable when the possibility of submucosal invasion can be definitively excluded and if the treatment is appropriately carried out. |
