Bleeding after ESD occurs in 4.1%–8.5% of patients who undergo gastric ESD. The "BEST-J score" is a prediction model to stratify the risk of bleeding after ESD for early gastric cancers. Nine factors were weighted with point values: 4 points for anticoagulants (warfarin, direct oral anticoagulants), 3 points for chronic kidney disease with hemodialysis, 2 points each for P2Y12 receptor antagonist (thienopyridine) and aspirin, 1 point each for cilostazol, a tumor size >30 mm, lower-third in tumor
