Efficacy of Hemospray in non-variceal upper gastrointestinal bleeding: a systematic review with meta-analysis.

ABSTRACT: Background:Recently, amongst other hemostatic modalities, Hemospray (TC-325) has emerged as an effective method for managing patients with non-variceal upper gastrointestinal bleeding (GIB). We conducted this systematic review and meta-analysis to assess the efficacy of Hemospray in patients with non-variceal upper GIB. Methods:Our primary outcomes were clinical and technical success; secondary outcomes were aggregate rebleeding, early rebleeding, delayed rebleeding, refractory bleeding, mortality, and treatment failure. A meta-analysis of proportions was conducted for all reported primary and secondary outcomes. A relative risk meta-analysis was conducted for studies reporting direct comparisons between Hemospray and other hemostatic measures. Results:A total of 20 studies with 1280 patients were included in the final analysis. Technical success of Hemospray was seen in 97% of cases (95% confidence interval [CI] 94-98%, I 2=52.89%) and a significant trend towards increasing technical success was seen during publication years 2011-2019. Clinical success of Hemospray was seen in 91% of cases (95%CI 88-94%, I 2=47.72%), compared to 87% (95%CI 75-94%, I 2=0.00%) for other hemostatic measures. The secondary outcomes of aggregate rebleeding, early rebleeding, delayed rebleeding, refractory rebleeding, mortality and treatment failure following the use of Hemospray were seen in 27%, 20%, 9%, 8%, 8%, and 31% of cases, respectively. Conclusion:Hemospray is safe, effective and non-inferior to traditional hemostatic measures for the management of non-variceal upper GIB, and can thus be used as an alternative option.
