To evaluate the role of transbronchial needle aspiration (TBNA) in the diagnosis of patients with enlarged mediastinal and/or hilar lymph node.Patients with mediastinal and/or hilar lymphoadenopathy proven by CT scan were eligible for TBNA as reported. All specimens were directly and instantly smeared for pathological examination.From June 1 2004 to December 31 2007, 164 patients were examined: including 80 lung cancers, 69 lung benign diseases, 2 other malignancy tumor, and 13 without definite diagnosis. Total 260 lymph nodes were punctured. TBNA procedures were successfully carried out in 445/463 (96.1%). Sensitivity of TBNA was 82.5% (66/80) in patients who had been proven to suffer from bronchogenic carcinoma. There were 25 patients that diagnosis of lung cancer was pathologically determined by TBNA only. A total of 122 lymph nodes in the 80 lung cancer patients were aspirated by TBNA with a positive rate of 65.6% (80/122). Severe complications were rare except small amount of bleeding at the TBNA site (100/164, 61.0%). From June 1 2006 to December 31 2007, lymph node tissues able to make histology diagnosis were yield in 73.5% (64/87) patients. Through histology pathology, the sensitivities of TBNA were 53.3% (8/15) for sarcoidosis and 78.6% (33/42) for lung cancer.TBNA is quite safe and helpful in diagnosis and staging of bronchogenic carcinoma, and in diagnosis of benign lung diseases.
