[Diagnostic value of transbronchial lung biopsy via fiberbronchoscope of peripheral or diffuse pulmonary disease]

To understand the diagnostic value of peripheral and diffuse pulmonary disease examined with Transbronchial lung biopsy (TBLB) via fiberoptic bronchoscope.

Four hundred and sixty patients of peripheral and diffuse pulmonary disease were diagnosed with TBLB via fiberoptic bronchoscope without fluoroscopic guidance. The result of clinical data and pathologic diagnosis were underwent retrospectively analyses.

Confirmed diagnosis was obtained in 351 patients; the total positive diagnostic rate was 76.3%. Diseases were included lung cancer, pulmonary tuberculosis, diffuse interstitial pulmonary fibrosis, pulmonary sarcoidosis etc. The positive diagnostic rate of TBLB on pleural pulmonary disorders was the lowest. There were no any other serious complications except bleeding, blood sputum, fever and pneumothorax occasionally.

TBLB in diagnoses of peripheral and diffuse pulmonary disease is a reliable, safe, handy cheap, may repeatable operational method.
