Efficacy of Endoscopic Tissue Adhesive in Patients with Gastrointestinal Tumor Bleeding.

Background Gastrointestinal tumors bleeding remains a significantly clinical challenge due to its resistance to conventional endoscopic hemostasis methods. While the efficacy of endoscopic tissue adhesives (ETA) in variceal bleeding has been established, its role in gastrointestinal tumor bleeding (GITB) remains ambiguous.Aims This study aims to assess the feasibility and effectiveness of ETA in the treatment of GITB.Methods The study enrolled 30 patients with GITB who underwent hemostasis through Histoacryl (R) tissue glue injection. Hemostasis success rates, ETA-related adverse events, and re-bleeding rates were evaluated.Results ETA application achieved successful hemostasis at all tumor bleeding sites, with immediate hemostasis observed in all 30 (100.0%) patients. Among the initially hemostasis cases, 5 patients (17.0%) experienced re-bleeding within 30 days, and the 60 day re-bleeding rate was 20.0% (6/30). Expect for one case of vascular embolism, no adverse events related with ETA application were reported. The 6 month survival was 93%.Conclusion ETA demonstrated excellent immediate hemostasis success rate in GITB cases and showed promising outcomes in prevention re-bleeding.
