[ Summary ] |
We assessed the clinical usefulness of conventional endoscopy for diagnosis of colorectal lesions. Observation of the color and shape of lesion is useful for differential diagnosis of neoplastic or non-neoplastic lesions. For the differential diagnosis of adenoma or carcinoma, observation of the presence of depressions, nodule on nodule and heterogeneity of color is useful. For differential diagnosis of M-SM s cancer or SM m cancer, observation of the presence of remarkable depression, submucosal tumor (SMT) like appearance at the edge of polypoid lesions, or observation of expansion and conversing folds at the circumference of lesion is useful. Conventional endoscopy is useful for diagnosis of colorectal lesions by using indigo carmine dye. |
