Clinical Trial Summary

This study is aimed to investigate the changes in pharmacokinetics and efficacy of antiplatelet agents before and after distal gastrectomy in gastric cancer patients taking oral antiplatelet agents for primary or secondary treatment for cardiovascular disease and to evaluate its impact on the occurrence of postoperative bleeding complications and thromboembolic events.

Eligibility

Inclusion Criteria:
