Objectives

Narrative objectives1

Two histopathological classifications, JSCCR and WHO 2019, are currently used for diagnosing serrated lesions in Japan. This study aimed to compare endoscopic diagnostic performance based on each criterion and to clarify features of discordant lesions (WHO-SSL but JSCCR-HP).
