Study objectives: To evaluate factors affecting the diagnostic yield of flexible fiberoptic bronchoscopy in evaluating solitary pulmonary nodules (SPNs).

Design: Retrospective analysis of bronchoscopies performed over a 4-year period.

Setting: A tertiary teaching hospital.

Patients: One hundred seventy-seven patients with pulmonary nodules without endobronchial lesions who underwent bronchoscopy with brushing, washing, and transbronchial biopsy.

Results: There were 151 malignant and 26 benign lesions. The diagnostic accuracy of bronchoscopy in malignant and benign lesions were 64% (97 of 151) and 35% (9 of 26), respectively. The yield of bronchoscopy was directly related to lesion size (p < 0.001, chi(2)). When lesions were grouped according to distance from the hilum, yields of bronchoscopy in central, intermediate, and peripherally located lesi...
