Diagnostic Value of Endobronchial Ultrasound Guided Transbronchial Needle Aspiration in Lung and Mediastinum Space Occupying Lesions
Abstract：Objective To evaluate the diagnostic value of endobronchial ultrasound guided transbronchial needle aspiration(EBUS - TBNA)in lung and mediastinum space occupying lesions. Methods 154 patients with lung and mediastinum space occupying lesions found by CT underwent EBUS - TBNA. All samples were analyzed by cytological smears and histopathological exminations. Results Among the 154 biopsy specimens,147 cases had histological com-parison. 109 cases were diagnosed as malignant lesions,9 cases as benign lesions and 5 cases as suspicious carcino-ma. Overall sensitivity,specificity and accuracy were 95. 5% ,100% and 95. 9% respectively using histological and clinical diagnosis. Conclusion The combination of cytology and histology in EBUS - TBNA is accurate,sensitive and specific for diagnosis and staging lung and mediastinum space occupying lesions.
