Sa1142 Clinical Outcomes of Endoscopic Submucosal Dissection for Colorectal Neoplasms: A Retrospective Multicenter Cohort Study

In Japan colorectal endoscopic submucosal dissection (ESD) received health insurance approval in April 2010, and it is now one of the most useful methods for treatment of early colorectal neoplasms. Good outcomes of colorectal ESD have been reported in advanced high-volume centers, but these procedures were performed by a limited number of highly skilled experts in specialized centers. The AIM of this study was to investigate the clinical outcomes of colorectal ESD and evaluate the feasibility of the procedure in a multicenter retrospective survey that included non-specialized public hospitals in Hiroshima prefecture in Japan.
