Colorectal creeping tumors were endoscopically studied in 411esions (39 cases) for thediagnosis of depth of invasion in comparison with histopathological results. Creepingtumors were classified into 3 types for the variation of the size of'nodules. Type I (211 esions) : The size of each nodule is uniform. Type II (8 lesions) : The size of each noduleis multiform. Type III (21 esions) : Giant nodules are seen m the tumor. The mean size oftumors in Type II and III was significantly larger than that of Type I. The incidence ofcarcinoma in adenoma was 91.7% in Type III, 50.0% in Type II, and 19.0% in Type I. Theredness of mucosal color or the depression on tumors was reliable sign for histologicaldiagnosis of carcinoma. There were 71esions of invasive carcinoma (sm ; 5cases, mp, 2cases) . Its characteristic features were giant nodules (3 cases) and depression on tumors (3 cases) . The indications for endoscopic rnucosal resection are Type I and II, bud Type III or the other types with depression may be considered as invasive carcinoma. We have todiagnose the depth of invasion correctly and select an adequate management, whichincludes a surgical operation, for the treatment of creeping tumors.
