Abstract
The purposes of the study: To assess the sensitivity of the trans-thoracic fine needle aspiration of the mass-like lung lesion and the factors influenced satisfied specimen. To evaluate the complication rate of this procedure and the factor that increased the risk of complication. Materials and Methods: This study was done retrospectively in the 320 patients had mass-like lung lesion who trans-thoracic fine needle aspiration were done under computed tomography guidance. Results: The satisfied specimen from this procedure was 92.2%. The sensitivity of this procedure was 91.5% for malignant lesion, 50% for tuberculous infection, and 34.4% for other infections or inflammatory lesions. The satisfactory of the specimen tended to decrease slightly in the deeper lesion. Pneumothorax was the most common complication, found in 14.4% and only 1.6% required intercostal chest drainage. The factors influenced increasing pneumothorax rate were passing of needle through emphysematous lung, passing of the needle through the fissure, and needle passing the lung more than 1 centimeter. Conclusion: The trans-thoracic fine needle aspiration of the mass-like lung lesion had high sensitivity especially in malignant lesions. The complications were low and mild. The most common complication was pneumothorax. To decrease risk of pneumothorax, avoidance of passing the needle through emphysematous lung and fissure should be considered.
