    Abstract:
    Objective This historical control study was performed to evaluate i) the rebleeding rate of bleeding colon diverticula treated with endoscopic band ligation (EBL) versus endoscopic clipping (EC) and ii) risk factors for rebleeding of diverticula initially treated by endoscopic hemostasis. Methods From January 2010 to December 2012, 68 patients were treated with EC, and from January 2013 to August 2016, 67 patients were treated with EBL. All patients in each group were followed up for one year to check for rebleeding. Results The rebleeding rate was lower in the EBL group (7 of 67, 10%) than in the EC group (21 of 68, 31%; p<0.01). This difference was mainly due to the lower rebleeding rate from the same hemorrhagic diverticulum initially treated by hemostasis (EBL: 4 of 67, 6%; EC: 15 of 68, 22%; p<0.01). The time span until rebleeding in the EBL group was ≤1 week. A multivariate analysis indicated that bleeding from the diverticula on the right side of the colon was a high-risk factor for rebleeding from the diverticula (odds ratio, 4.48; 95% confidence interval, 1.22-16.46; p=0.02). Conclusion The low rebleeding rate in the EBL group was attributed to the low degree of rebleeding from the same diverticulum, indicating that EBL was superior to EC in preventing rebleeding of an initially treated diverticulum.
