Background: Hemorrhage is one of the most serious complications of endoscopic sphincterotomy (EST). The risk factors for delayed hemorrhage are not clear. This study aimed to explore the risk factors for post-EST delayed hemorrhage and suggest some precautionary measures.Methods: This study analyzed 8477 patients who successfully underwent endoscopic retrograde cholan- giopancreatography (ERCP) and EST between January 2007 and June 2015 in the First Affiliated Hospital of Nanchang University. Univariate and multivariate analyses were performed to find the risk factors for delayed hemorrhage after EST. Results: Of the 8477 patients screened, 137 (1.62％) experienced delayed hemorrhage. Univariate analysis showed that male, the severity of jaundice, duodenal papillary adenoma and carcinoma, diabetes, intraop- erative bleeding, moderate and large incisions, and directional deviation of incision were risk factors for post-EST delayed hemorrhage ( P < 0.05). Multivariate analysis showed that intraoperative bleeding [odds ratio (OR) = 3.326; 95％ CI: 1.785–6.196; P < 0.001] and directional deviation of incision (OR = 2.184; 95％ CI: 1.266–3.767; P = 0.005) were independent risk factors for post-EST delayed hemorrhage. Conclusions: Delayed hemorrhage is the most common and dangerous complication of EST. Intraoperative bleeding and directional deviation of incision are independent risk factors for post-EST delayed hemor- rhage.
