 We reviewed the clinical usefulness of NBI(narrow band imaging)endoscopy in its improvement of detection of colorectal neoplasia, differential diagnosis between neoplasia and non-neoplasia, pit pattern diagnosis and invasion depth diagnosis of carcinoma in colorectal neoplasia. NBI is commonly considered to be useful in differential diagnosis between neoplasia and non-neoplasia & pit pattern diagnosis for regular pits without chromoendoscopy. NBI magnification is expected to be useful in qualitative diagnosis of colorectal carcinoma through assessment of both microvessel structure and pit like pattern on the lesion surface(NBI Hiroshima Classification). Also, we introduced several NBI magnification classifications for colorectal tumor in Japan. Furthermore, we proposed a new non-magnification NBI classification for colorectal tumor(CTNIG Classification).
