Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the diagnosis of upper gastrointestinal tumors

Introduction: Endoscopic ultrasound (EUS) is an accurate imaging modality in the staging of gastrointestinal tumors, in the differential diagnosis of subepithelial lesions and pancreatobiliary disorders. The EUS-guided fine needle aspiration (FNA) significantly increased the diagnostic value and sensitivity of EUS in the identification of malignancies. Aims: To evaluate the diagnostic yield of the EUS-guided FNA in cyto-histological diagnosis of upper gastrointestinal tumors, particularly for the focal lesions of the pancreas. Patients and methods: 49 patients who underwent EUS-guided FNA from April 2011 in our…
