A241 APPLICATION OF NEXT GENERATION QUALITY AND EXPERT-LED CASE REVIEW TO INCREASE THE CONSISTENCY OF SESSILE SERRATED ADENOMA DIAGNOSTIC RATES: A CANADIAN TERTIARY-CARE CENTRE EXPERIENCE

摘要

BackgroundSessile serrated adenomas (SSAs) are known precursors of colorectal adenocarcinoma. Accurate identification and classification of SSAs have important clinical implications. Despite attempts to establish universal criteria for the histologic diagnosis of SSA, significant variability exists in the pathologist diagnostic rate (PDR) of SSAs compared to tubular adenoma (TA).
