 Serrated neoplasia pathway is the canceration from hyperplastic polyps. There are various opinions about the treatment of serrated lesions, but the presence of tumorigenesis, especially cytological dysplasia in SSA/P, which is clear in our study, is usually the presence of two-step ridges/nodules and redness in endoscopy ; furthermore, using J-NET and pit pattern classifications in magnifying endoscopy to identify the existence of tumors is useful, thereby greatly contributing to the treatment indication for serrated lesions of the colon. We also anticipate the endoscopic diagnosis tools, such as ultramagnifying endoscopes and AI.
