Abstract

PURPOSE: The purpose of this study was to evaluate the usefulness of combined automated gun biopsy (AGB) and fine needle aspiration (FNA) in the diagnosis of lung lesions.
MATERIALS AND METHODS
Lung lesions in 102 patients were aspirated consecutively using a 21-gauge fine needle and biopsied with an 18-gauge automated gun at intervals of 3 -5 minutes. Final diagnosis was based on the findings of surgery or clinical follow-up.
RESULTS
In 50 patients with malignant lesions, diagnostic accuracy was 80% with AGB and 76% with FNA, but using the combined modality, the figure was 94%. In 52 patients with benign lesions, diagnostic accuracy was 54% with AGB and 50% with FNA; using the combined modality, 69 percent accuracy was achieved. For all lesions, the diagnostic accuracy of the combined modality was thus significantly higher than that of a single method (p<.05). The complications which occurred were pneumothorax in six cases (5.9%), chest tubing in two (0.2%) and minor hemoptysis in nine (8.8%).
CONCLUSION
In the diagnosis of lung lesions, the combined use of AGB and FNA is safe and can increase diag-nostic accuracy.
