BACKGROUND: Hemorrhage is one of the serious adverse events of endoscopic sphincterotomy (EST). However, the risk factors for delayed hemorrhage after EST have not been clarified. The aim of this study was to examine the risk factors for delayed hemorrhage after EST. METHODS: Consecutive patients who underwent EST between January 2011 and December 2015 were analyzed retrospectively. The incidence, treatment outcomes, and risk factors for delayed hemorrhage were evaluated. Delayed hemorrhage was defined as symptomatic hemorrhage occurring 24 h after an endoscopic procedure. RESULTS: After analyzing 1113 patients who underwent EST, delayed hemorrhage was seen to occur in 30 (2.7%) patients. The median period before presentation of delayed hemorrhage was 2 days (range 1-6) after EST, and its severity was mild in four, moderate in 20, and severe in six patients. All patients with delayed hemorrhage received successful endoscopic hemostasis. Univariate analysis showed that delayed hemorrhage occurred more frequently in patients with hemodialysis (p = 0.013), heparin replacement of antithrombotic agents (p = 0.012), or early hemorrhage occurring just after EST (p < 0.001). Among these, hemodialysis (OR 6.44, 95% CI 1.67-24.8; p = 0.007), heparin replacement (OR 3.76, 95% CI 1.42-9.98; p = 0.008), and early hemorrhage (OR 4.35, 95% CI 1.90-9.96; p < 0.001) proved to be independent risk factors for delayed hemorrhage on multivariate analysis. CONCLUSIONS: The incidence of delayed hemorrhage after EST was 2.7%. Hemodialysis, heparin replacement, and early hemorrhage were the risk factors for delayed hemorrhage.
