| [ Summary ] |
This study was carried out to determine the therapeutic efficacy of colonoscopic resection, in cluding piecemeal mucosal resection. During the period from January 1990 to June 2000, we colonoscopically resected 419 lesions which were 20mm or larger in size (Ip 188, Isp 90, Is 38, IIa and LST 103). We analyzed 130 lesions (Isp 46, Is 26, IIa and LST 58) which could be sufficiently evaluated in respect to cure rates. They were observed for an average of 22.4 months (max 103 months), excluding Ip lesions and operative lesions, after colonoscopic resection, because of submucosal invasion and perforation. One hundred twenty nine lesions were completely cured colonoscopically. One lesion was operated on after colonoscopic resection because of suspicions about local residue. However, pathological examination was not performed on local residue. In conclusion, colonoscopic resection of large polyps exhibits excellent therapeutic efficacy. |
