Computed Tomography-Guıded Tru-Cut Bıopsy in the Dıagnosıs of Lung Lesıons; Our Clınıcal Experience.

INTRODUCTION

CT-guided tru-cut biopsy, which is less invasive and cost-effective, is an important diagnostic tool with high accuracy in lesions located peripherally in the lung. In this article, CT-guided tru-cut biopsy experiences of thoracic surgeons are shared.

MATERIALS AND

METHODS

CT-guided tru-cut biopsy was performed on 200 patients with suspected lung lesions in the thoracic surgery clinic. Diagnostic rates of biopsies, complications, factors affecting the development of complications, and complication management were examined.

RESULTS

The diagnostic rate of the biopsies was 88%. Pneumothorax developed in 19.5% and hemothorax in 1% after the procedure. There was a significant relationship between mass dimensions and total complication rates (p=0.017). The relationship between the distance among the pleura and the mass and the development of complications was significant (p<0.001). The relationship between the number of biopsies and the development of pneumothorax was significant (p=0.011). The relationship between the size of the mass and the development of pneumothorax was significant (p=0.011). In univariate binary logistic regression analysis, a significant correlation was found between the size of the mass and the development of total complications (odds ratio (OR)=0.356 (95% CI: (0.146-0.868), (p=0.023)).

DISCUSSION: In the diagnosis of lung lesions, CT-guided tru-cut biopsy is an effective diagnostic tool with high diagnostic power, with its less invasiveness, and lower cost. The increase in the lung parenchyma distance passed with the biopsy needle increased the likelihood of complications most significantly. The size of the mass and the number of biopsies also had significant effects on the development of complications.
