Abstract:
Objective:To evaluate the diagnostic value of endobronchial ultrasonography(EUS)-guided fine-needle aspi-ration(FNA)in diagnosis of lung cancer.Methods:EUS-guided FNA was used in16patients suspected of lung cancer of sub-mucosal and parabronchial structures.Bronchoscopic methods failed to detect any abnormality in them.Results:Final diag-noses were made in15patients,including8cases of bronchopulmonary adenocarcinoma,4cases of bronchopulmonary squa-mous carcinoma and3cases of lymphatic metastasis of bronchral adenocarcinoma.The sensitivity of EUS-guided FNA was 93.8%. There was no severe complications associated with the use of EUS.No patients developed bleeding or pneumatotho rax.Conclusion:EUS is useful in detecting pathologic changes in the submucosal and parabronchial structures.EUS guided FNA is accurate and safe for diagnosis of lung cancer,especially in small nodes.
