Abstract:
Objective To evaluate the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and conventional-transbronchial needle aspiration (C-TBNA) in mediastinal and lung hilar lesions. Method 301 cases of lung hilar and mediastinal lesions were selected from 2010 to 2016. Among them, 183 cases underwent TBNA, and the other 118 cases received EBUS-TBNA technology. During the research, the associations of diagnostic positive rate and complications were analyzed in order to explore the advantage and the value of EBUS-TBNA. Results The positive rates of EBUS-TBNA in central groups (2R, 4L, 4R, 7) were higher than in the peripheral groups (10R, 10L, 11R, 11L) (P < 0.05). When studying the lymph node group 2R, 4R and 7R, the positive rate of EBUS-TBNA is much more significant than conventional TBNA (P < 0.05); When biopsying at the lymph node group R4 and group 7, one needle positive rate of EBUS-TBNA were much more superior than TBNA (P < 0.05), the three needles cumulative positive rate of EBUS-TBNA almost reach the total positive rate(P > 0.05), an approving effect of puncture can be acquired; The accuracy and sensitivity of EBUS-TBNA in the diagnosis of lung hilar and mediastinal lesions were much better than conventional TBNA (P < 0.05), especially the diagnostic positive rate of EBUS-TBNA in benign diseases was higher (P < 0.05); The complications rates in both two technologies were not significantly different (P > 0.05), there were no severe complications during the operations in all cases. Conclusion EBUS-TBNA is useful in diagnosis of mediastinal and hilar lesions of unknown reason, and significant in diagnosis of bronchial and extrabronchial diseases. It is an efficiency and safe operation while further application studies are needed.
