Size, Experience, Location, Fibrosis (SELF) nomogram demonstrating score of 5 correlating with high risk of perforation (11.6%) in a patient with 5-cm rectal polyp without fibrosis when lesion removal is performed by a physician with limited (fewer than 50 procedures) experience in endoscopic submucosal dissection (ESD).
