Abstract
BackgroundRecently, 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.MethodsOur 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.ResultsA 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%, I2=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%, I2=47.72%), compared to 87% (95%CI 75-94%, I2=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.ConclusionHemospray 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.
