The preventive effects of endoscopic hemostasis for rebleeding of colonic diverticular hemorrhage (CDH) remain controversial. We retrospectively evaluated the risk factors for rebleeding after endoscopic hemostasis for CDH. This study included 146 patients treated with endoscopic hemostasis for CDH from April 2013 to December 2017. We initially achieved endoscopic hemostasis in all patients without any severe complications. Of 146 patients, early rebleeding (i.e. rebleeding within 30 days after initial hemostasis) occurred in 27 patients and late rebleeding occurred in 37 patients. The risk factor for early rebleeding was hemostasis by non-ligation method (odds ratio: 3.62; 95% CI: 1.13-15.22; P=0.025) according to the multivariate analysis. Risk factors for late rebleeding were history of diverticular hemorrhage (odds ratio: 3.36; 95% CI: 1.32-8.51; P=0.011) and ischemic heart disease (odds ratio: 9.76; 95% CI: 3.28-29.00; P<0.001). These findings suggest endoscopic hemostasis might not be able to prevent late rebleeding. The ligation method could be a first-line treatment for CDH.
