 Lesions and use of antiplatelet drugs. Patients treated with anticoagulants, cilostazol, and surgical resection were excluded. A total of 350 patients were included in the analysis. The patients were divided into groups based on their use of antiplatelet therapies (APTs). In the single APT group, 53 patients received low dose aspirin (LDA), and 5 patients received a thienopyridine. LDA was continued during endoscopic submucosal dissection (ESD) in 14 of 58 patients in the single APT group and 24 of 31 patients in the dual APT (DAPT) group.
