Objective To explore the diagnostic value of video bronchoscope-guide transbronchial needle aspiration(TBNA) combined with transbronchial lungbiopsy(TBLB) on pulmonary sarcoidosis.Methods Twenty-two patients,definitely diagnosed as stage Ⅰ pulmonary sarcoidosis,were enrolled into the study and accepted TBNA and TBLB.Results The positive diagnostic rates of TBNA and TBLB were 63.6%(14/22) and 40.9%(9/22),but the rate increased to 90.9%(20/22) when the two methods were used together,which showed significant differences(x2=12.24,4.66,P<0.01 or <0.05).Conclusion TBNA combined TBLB test is a safetymethod with high diagnostic accuracy for pulmonary sarcoidosis.
