 Endoscopic piecemeal mucosal resection(EPMR)according to plan for resection of large colorectal tumors is generally known. We evaluated161colorectal tumors diagnosed as Type V pit pattern.68.6% of submucosal cancers deeper than1,000μm showed Type VI(higher irregularity pattern)and Type VN pit pattern. The rate of occurrence of the lesion diagnosed as Type V pit pattern in the area of cancer was64% in50early colorectal cancers with as adenoma component. Magnifying colonoscopy is useful for EPMR according to plan when Type V pit pattern is abserved. Granular type of laterally spreading tumor(LST-G)is a good indication for EPMR. According to our study, the mean size of remnant or recurrent colorectal tumors after EMR was6.8mm. Using magnifying colonoscopy, the remnant or recurrent tumor after EMR was detected clearly.
