The role of transbronchial lung biopsy in diffuse pulmonary disease.
Forty consecutive patients underwent flexible fiberoptic transbronchial lung biopsy for diagnosis of diffuse nodular or infiltrative lung disease. Biplane fluoroscopic examination with image intensification greatly facilitated accurate placement of the biopsy forceps near the pleura; Specimens of lung parenchyma were obtained for culture and histological study in every  case. A pathological diagnosis was correctly established in 34 of 40 patients. Transbronchial biopsy was helpful in the clinical management of an additional 4 patients. Biopsy results were not accurate in 2 patients. No significant morbidity was associated with the procedure. Fiberoptic transbronchial lung biopsy is a safe and useful adjunct to the diagnosis of parenchymal lung disease.
