Abstract
Transbronchial forceps biopsy (TBB) of the lung through the fiberoptic bronchoscope was performed in 74 patients. A histological diagnosis compatible with the clinical course, and roentgenographic appearance was obtained in 47 (64%) patients. There were six cases with inadequate tissue and ten cases where TBB was both nondiagnostic and of no other benefit in the subsequent management of the patient. This procedure was of particular value in evaluation of acutely ill patients with diffuse parenchymal disease. TBB either gave a specific diagnosis or correctly influenced patient management in 14 (89%) of 16 acutely ill patients with diffuse parenchymal disease. There was no uncontrollable hemorrhage; in one patient (15%) pneumothorax occurred. The safety and diagnostic value of this technique in the diagnosis of diffuse lung disease is proven.
