 This report reviewed the invasion depth for the diagnosis of colorectal neoplasia using magnifying colonoscopy and focused on pit pattern and NBI. Despite the establishment of the pit pattern classification(Kudo & Tsuruta), the diagnostic criteria for severe irregular VI type pit pattern remains unclear. As for NBI, we introduced the NICE and JNET classification. In these classifications, both vessel and surface patterns are essential for application. Except the JNET classification type 2B, each JNET category is sufficient for characterizing colorectal neoplasia. Furthermore, the diagnostic ability of type 2B is relatively low compared with that of other categories. Based on this fact, pit pattern diagnosis with chromoagents, such as indigo carmine or crystal violet, should be added to cases showing type 2B or in categories with a low confidence in the use of JNET classification.
