 We assessed the clinical usefulness of conventional endoscopy for diagnosis of colorectal lesions. Observation of the color and shape of the lesions is useful for differential diagnosis of neoplastic or non-neoplastic lesions. For the differential diagnosis of adenoma or carcinoma, observation of the presence of depression, nodule on nodule and heterogeneity of color is useful. For differential diagnosis of M to SM slight cancer or SM massive cancer, observation of the presence of remarkable depression, submucosal tumor like appearance at the edge of a polypoid lesion, or observation of expansive appearance and poor extension at the circumference of the lesion is useful. Overall accuracy for the differential diagnosis of M to SM slight cancer or SM massive cancer using conventional endoscopy is 77.6%. Conventional endoscopy is useful for diagnosis of colorectal lesions.
