[A comparative study on manual and coaxial automated percutaneous lung biopsy].

Objective: To evaluate the difference in diagnostic accuracy and complication rate and operational procedures between manual and coaxial automated percutaneous lung biopsy under CT-guidance.

Methods: Ninety-seven patients [aged from 19 - 87 (50 ± 17) years], with undiagnosed pulmonary lesions underwent CT-guided percutaneous lung biopsy from June 2006 to May 2010 in this hospital. The final diagnosis was confirmed by surgical pathology or clinical follow-up.

[A comparative research on the conventional transbronchial needle aspiration and endobronchial ultrasound-guided transbronchial needle aspiration for the diagnosis of mediastinum lesions].

Objective: To compare the diagnostical yields and complication of conventional transbronchial needle aspiration (TBNA) and endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) for the mediastinum lesions under the same condition.

Method: Ninety-five patients with mediastinal lesions on chest CT were included. Bronchoscopy was performed under the local anesthesia, TBNA, EBUS-TBNA performed sequentially as a single combined procedure.
