Abstract

Background and Aims: It is controversial whether anticoagulant therapy increases the risk of bleeding after Endoscopic Submucosal Dissection (ESD). The aim of this study is to evaluate the effects of anticoagulant therapy on gastric ESD.Methods: Patients who underwent gastric ESD in Toranomon Hospital between April 2005 and July 2017 were enrolled. The risk of post-ESD bleeding was evaluated using multivariate cox proportional hazards analysis.Results: Of 1979 patients enrolled, 49 were taking anticoagulant agent; 25 discontinued warfarin and switched to heparin alternative therapy during ESD, whereas 24 discontinued DOAC (Direct oral anticoagulant). During 2 months of the entire observational period, post-ESD bleeding occurred in 88 patients (4.4%): 80 patients without any anticoagulant agent (4.1%), 8 patients with anticoagulant agent (9.1%); 4 patients with a warfarin (16.0%), 4patients with DOAC (16.7%). In multivariate analysis, anticoagulant therapy [hazards ratio (HR) 6.24, 95% confidence interval (CI): 2.93–13.27], warfarin (HR4.19, 95% CI: 2.10–16.62), DOAC (HR6.71, 95% CI: 2.39-18.82) were independent risk factors of post-ESD bleeding.Conclusion: Because anticoagulant therapy significantly increases the risk of post-ESD bleeding, it should be necessary to strictly management at least two weeks after ESD.
