摘要
Background and Aims: We previously reported preliminary safety results for a new method, endoscopic detachable snare ligation (EDSL), for diverticular hemorrhage. This method does not need endoscope removal to attach a ligation device after detection of the bleeding site. The aim of the present study was to evaluate the efficacy and safety of EDSL in a larger patient population.
Methods: This prospective study was conducted in 12 institutions. Patients suspected of having diverticular hemorrhage without serious systemic disease were enrolled. The primary endpoint was early (within 30 days) recurrent bleeding rate in patients treated with EDSL. The secondary endpoints were overall early recurrent bleeding rate in patients with definite diverticular bleeding and adverse events in patients treated with EDSL.
Results: From June 2015 to March 2017, bleeding diverticula were detected in 123 of 205 enrolled patients (60%), of whom 101 (82%) were treated with EDSL. Most patients (20/22) in whom EDSL was not successful were treated with clipping. The early recurrent bleeding rate was 7.9% (95% confidence interval, 2.6%-13.2%; 8/101) in patients who could be treated with EDSL. The median total endoscopic and EDSL procedure time was 40 minutes (inter-quartile range, 15-71) and 4 minutes (interquartile range, 1-7), respectively. Two mild adverse events, colonic diverticulitis and temporary abdominal pain, were observed.
Conclusion: EDSL was confirmed to be useful and safe for treatment of colonic diverticular hemorrhage. (Clinical trial registration number: UMIN 000001858.)
