BACKGROUND & AIMS: Standard endoscopic therapies do not control bleeding or produce complications in as many as 20% of patients with nonvariceal gastrointestinal bleeding. Most bleeding comes from ulcers with characteristics such as high-risk vascular territories and/or large vessels. We evaluated the efficacy of using over-the-scope clips (OTSCs) as primary or rescue therapy for patients with bleeding from lesions that have a high risk for adverse outcomes. METHODS: We performed a retrospective analysis of data from 67 patients with gastrointestinal bleeding from high-risk lesions who were treated with OTSCs as primary (n = 49) or rescue therapy (n = 18) at a quaternary center, from December 2011 through February 2015. The definition of high-risk lesions was lesions that were situated in the area of a major artery and larger than 2 mm in diameter and/or a deep penetrating, excavated, fibrotic ulcer with high-risk stigmata, in which a perforation could not be ruled out or thermal therapy would cause perforation, or lesions that could not be treated by standard endoscopy. Clinical severity was determined based on the Rockall score and a modified Blatchford score. Our primary outcome was the incidence of rebleeding within 30 days after OTSC placement. We assessed risk factors for rebleeding using univariate hazard models followed by multivariable analysis. RESULTS: Of the 67 patients, 47 (70.1%) remained free of rebleeding at 30 days after OTSC placement. We found no difference in the proportion of patients with rebleeding who received primary or rescue therapy (hazard ratio, 0.639; 95% confidence interval, 0.084-4.860; P = .6653). Only 9 rebleeding events were linked clearly to OTSCs and required intervention, indicating an OTSC success rate of 81.3%. We found no significant associations between rebleeding and clinical scores. However, on multivariable analysis, patients with coronary artery disease had a higher risk of rebleeding after OTSC independent of international normalized ratio and antiplatelet use (hazard ratio, 7.30; P = .0002). CONCLUSIONS: In a retrospective analysis of 67 patients with bleeding from high-risk gastrointestinal lesions, we found OTSCs to prevent rebleeding in more than 80% of cases. In the past, these lesions were treated with surgical or radiologic interventions. Patients with coronary artery disease have an increased risk of rebleeding after OTSCs, suggesting the need for escalated therapies.
