A systematic description of the post-EMR defect to identify risk factors for clinically significant post-EMR bleeding in the colon

and Aims: Clinically significant bleeding (CSPEB) is the most frequent serious adverse event after endoscopic mucosal resection (EMR) of large laterally spreading colonic lesions (LSLs). There is no proven prophylactic therapy, and it remains a significant drawback of EMR. We aimed to systematically describe and evaluate the features of the post-EMR mucosal defect (PED) and their relationship to CSPEB.
