| [ Summary ] | Endoscopic diagnostics has remarkably advanced in the last few decades using magnifying endoscopy and pit fissure diagnosis. Although pit pattern diagnostics are evolving into standard methods, simply applying them to the classification categories, such as card games, is not effective. The first reason is that the pit pattern classification is established for colorectal epithelial neoplastic lesions (adenomas, cancers) and does not cover other lesions. Second, the pit pattern has a subtype, even in adenomas and cancers. Thirdly, it is not possible to cope with the change in the concept of pathology. However, it can be mastered by understanding the observation technique of a magnifying endoscope, theory of pit patterns, and effects of pathogenesis on the magnifying findings. | |
