Antithrombotic drugs were withdrawn following the 2017 guidelines (Appendix on anticoagulants including DOACs). To further clarify differences in antithrombotic agents' effects, the peri\u2010cancerous mucosa in the resected specimen was pathologically evaluated according to the Updated Sydney System. Multivariate analysis was performed to assess the risk of post\u2010ESD bleeding.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The incidence of post\u2010ESD bleeding in patients taking DOACs was 19.6% (10\/51). Among patients taking antithrombotic drugs, DOACs were identified as a possible factor involved in post\u2010ESD bleeding (odds ratio [OR] 4.92). Among patients taking DOACs, possible factors included resection length diameter \u226530\u2009mm (OR 3.72), presence of neutrophil infiltration (OR 2.71), lesions occurring in the lower third of stomach (OR 2.34), and preoperative antiplatelet use (OR 2.22). Post\u2010ESD bleeding by DOAC type was 25.0% of patients (4\/16) receiving apixaban, in 20.0% (3\/15) receiving edoxaban, in 21.4% (3\/14) receiving rivaroxaban, and in none of those receiving dabigatran.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The administration of DOACs was shown to be a possible factor involved in post\u2010ESD bleeding, and risk factors for patients taking DOACs included neutrophil infiltration. The pharmacological differences in the effects of DOACs contributing to bleeding in gastric ulcers suggest comparatively less bleeding with dabigatran after
