Forty two patients with early colorectal cancer were studied to evaluate the results of endscopic piecemeal polypectomy from 1992 to 1996. The number of piecemeal resection was most frequent, about 5 times, in nodule-aggregating lesions in configuration of tumor and about 6 times in lesions over 30mm in size of tumor. There were 36 patients in whom all piecemeal specimens could be obtained. The average maximum diameter of the specimen was about 14mm and the depth of cancer invasion could be diagnosed in all patients. In 35 patients with mucosal cancer, no recurrence was seen. In 4 of 7 patients with submucosal cancers, complete resections was performed, but local recurrence was seen in 1 patients. In 3 patients residual cancer was noted and additional surgical resec-tions was performed. Two patients had residual cancer in resected specimens and another patient . had lymph node metastases. These results showed that endoscopic piecemeal polypectomy was useful for mucosal cancer but should be indicated cautiously for sub-mucosal cancer.
