 We have reported endocytoscopy(EC), an ultra-high magnification system, which enables us to observe not only the structural atypia but also the cellular atypia in colorectal lesions. In this study, we used the integrated type EC(XCF-260EC1, Olympus, Tokyo, Japan). We classified the EC findings into 5 groups(EC classification)and evaluated the usefulness of the classification for differential diagnosis. Positive predictive value of each EC group was as follows. EC 1b(hyperplastic polyp): 100%. EC 2(adenoma): 75.0%. EC 3b(invasive cancer): 98.4%. In lesions of EC 3a, 9.1% were adenomas and 45.5% were invasive cancers. As for the differentiation between neoplastic(EC 2.3)and non-neoplastic(EC 1)lesions, the EC diagnosis corresponded with the pathological diagnosis completely. The integrated type EC system enabled us to observe colorectal lesions at the cellular level in vivo. Our classification of EC images corresponded well with the final pathological diagnosis. Endosytoscopy was especially useful for differential diagnosis between neoplastic and non-neoplastic lesions and for diagnosing invasive cancers.
