In this retrospective cohort study of 55 patients at a tertiary care center, we evaluated Hemospray as either a primary or salvage endoscopic hemostatic therapy. Immediate hemostasis was achieved in 100% of primary cases and 97% of salvage cases. Although not statistically significant, rebleeding occurred less frequently in the primary group (14%) than in the salvage group (30%). Patients in the primary therapy group required fewer post-procedure transfusions and had shorter hospital stays, though this may be related to the differing bleeding etiologies rather than treatment modality. Mortality did not differ significantly between groups. These findings align with previous literature highlighting high rates of immediate hemostasis but variable rebleeding outcomes. While concerns persist about long-term hemostatic durability, particularly in monotherapy use, Hemospray\u2019s efficacy in treating bleeding from tumors and friable lesions\u2014especially when used as a primary modality\u2014underscores its clinical value. Despite limitations related to sample size and study design, our results support Hemospray\u2019s role as an effective primary or adjuvant intervention for both upper and lower GIB.<\/jats:p>","DOI":"10.1177\/10815589261451201","type":"journal-article","created":{"date-parts":[[2026,5,6]],"date-time":"2026-05-06T06:15:36Z","timestamp":1778048136000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["The clinical utility and outcomes of Hemospray as primary versus salvage therapeutic modality for endoscopic hemostasis: A retrospective cohort study"],"prefix":"10.1177","author":[{"given":"Keith R.","family":"Garrison","sequence":"first","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Texas Tech University Health Sciences Center, El Paso, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luis O.","family":"Chavez","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Texas Tech University Health Sciences Center, El Paso, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeff Angelo","family":"Taclob","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Texas Tech University Health Sciences Center, El Paso, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandro","family":"Robles","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Texas Tech University Health Sciences Center, El Paso, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marc J.","family":"Zuckerman","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Texas Tech University Health Sciences Center, El Paso, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sherif E.","family":"Elhanafi","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology and Hepatology, Texas Tech University Health Sciences Center, El Paso, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,5,5]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.giec.2015.02.008"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bpg.2007.10.011"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2036.2011.04651.x"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/jgh.14114"},{"key":"e_1_3_2_6_2","first-page":"654","article-title":"Acute lower GI bleeding in the UK: patient characteristics, interventions and outcomes in the first nationwide audit","volume":"67","author":"Oakland K","year":"2018","unstructured":"Oakland K, Guy R, Uberoi R, et al.
