[215 cases of diffuse pulmonary disease diagnosed with transbronchial lung biopsy via bronchofibroscope].

215 cases of diffuse pulmonary disease diagnosed with transbronchial lung biopsy (TBLB) via bronchofibroscope were reported. The incidence of successful biopsy was 96.7%. The total diagnostic rate was 80.5%. There were no other serious complications except for bloody or blood-streaking sputum, but the amount rarely exceeded 50 ml, and pneumothorax occurred occasionally. It was suggested that TBLB is an easy, safe and useful method for diagnosing diffuse pulmonary disease.
