[Transbronchial needle aspiration in routine bronchoscope practice].
OBJECTIVE
To evaluate the yield of transbronchial needle aspiration (TBNA) in a clinical routine bronscopy practice after training under the guide by CT scanning.


METHODS
Using Wang TBNA System and CT scanning methods to define the site in airway for puncturing the enlarged mediastinal lymphnode. The positive rate of TBNA was 64%, almost equal to the positive rate (61%) of the method by operating directly under CT scanning. TBNA was performed on 100 consecutive patients with 152 enlarged mediastinal nodes undergoing diagnostic fiberoptic bronchoscopy.


RESULTS
The positive rate (64%) was equal to the positive rate (61%) under the CT guide.


CONCLUSIONS
CT guiding TBNA is very useful for training doctors to learn the TBNA technique, and TBNA can be done very well and play an important role in routine bronchoscope practice.
