The role of bronchoscopy and needle aspiration in the diagnosis of peripheral lung masses.
Sixty patients underwent flexible fiberoptic bronchoscopy and percutaneous needle aspiration of peripheral lung lesions with fluoroscopic monitoring. A single general anesthetic was used. We found that percutaneous needle aspiration was the more accurate of the two procedures in establishing a diagnosis but that flexible fiberoptic bronchoscopy proved complementary in some instances. The incidence of pneumothorax was 27% but aspiration was needed in only 8%. There were no other complications. In 84% of patients with primary carcinoma of the lung presenting as a peripheral lesion, the diagnosis was established by these procedures. The accuracy was less in metastatic lesions and considerably less in benign lesions.
