Su1619 Is it possible to identify endoscopically the colorectal serrated lesion with early cancer

Serrated lesions of the colorectum, such as hyperplastic polyps (HPs), traditional serrated adenoma (TSAs) and sessile serrated adenomas/polyps (SSA/Ps), are important contributors to colorectal carcinogenesis. Thus, reliable identification of the presence of a cancer component in serrated lesions has important clinical implications. The aim of this study was to analyze the potential of conventional endoscopy and advanced endoscopic imaging techniques, including chromoendoscopy and narrow band imaging, to delineate the characteristic features of serrated lesions with cancer.
