 The recently proposed oncogenic pathway in colorectal lesions with serrated structures, i.e., the serrated pathway, has drawn attention to the serrated lesions of the colon and rectum. However, management of such lesions remains controversial. In the present study, to clarify how they should be managed, we examined endoscopic findings and histopathologic findings of hyperplastic lesions, sessile serrated lesions, and classic serrated adenoma. As a result, in the event that normal endoscopy shows reddening, pitting, and two-tiered rounded protuberances; narrow band imaging magnification shows capillary pattern type III ; or pit pattern magnification shows pit pattern type V, concurrent cancer is strongly suspected, and the lesion should be actively resected.
