Abstract

Introduction: The current standard of treatment for non-variceal upper GI bleed (NVUGIB) includes endoscopic hemostasis with either through-the-scope clips or thermal therapy. However, they may be associated with rebleeding, especially in high-risk ulcers. The use of over-the-scope clips (OTSC) has been demonstrated in multiple recent studies to be an effective measure for NVUGIB. We aimed to analyze the current literature on standard therapy with OTSC for the management of NVUGIB. Methods: A meta-analysis was performed by pooling the data from randomized studies obtained from a comprehensive search of Medline, Embase, and Scopus from inception to February 2023. The outcomes analyzed included rates of persistent bleeding, rebleeding, mortality, and duration of hospitalization. Results: A total of 5 studies were included in the final analysis. There was no significant difference in the risk of persistent bleeding between the groups, with a risk ratio (RR) of 0.29 [95% confidence interval (CI): 0.07 – 1.27]. The use of OTSC was associated with a significantly lower risk of 7-day and 30-day rebleeding compared to standard therapy with RR of 0.30 (95% CI: 0.16 – 0.59) (Figure 1A) and 0.42 (95% CI: 0.24 – 0.72) (Figure 1B), respectively. There was no difference in the risk of 30-day mortality or the duration of hospitalization. On a subgroup analysis of studies using OTSC as a first-line therapy, there was no change in the effect. Conclusion: The use of OTSC can reduce the rebleeding rates after endoscopic hemostasis. However, OTSC may not reduce the risk of persistent bleeding or mortality. Future studies are required on the cost-efficacy of this modality
