The major gastrointestinal endoscopy society guidelines list endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) as a high-risk procedure for bleeding. However, there are no studies evaluating the risk of bleeding for EUS-FNA of solid organs while patients continue to take clopidogrel. The aim of the present case series was to evaluate the rate of bleeding in a cohort of patients who underwent EUS-FNA for solid lesions while on clopidogrel. Bleeding was measured at the time of the procedure by bleeding seen on EUS, endoscopic visualization of blood, or drop in hemoglobin after the procedure. From 2013 to 2015, 10 patients were identified for this case series. Lesions that underwent EUS-FNA included gastric and rectal subepithelial lesions, pancreas masses, and liver masses. No immediate or delayed bleeding was observed in any of the patients. EUS-FNA of solid lesions on clopidogrel may not be a high-risk procedure for bleeding. Larger studies are needed to confirm this finding.
