Abstract

PURPOSE
Results of 181 percutaneous needle aspiration biopsies performed with an 18-gauge needle during a period of 3 years were analyzed to determine efficacy and safety of the procedure.
MATERIALS AND METHODS
Biposies were performed in patients that could not be diagnosed by bronchoscopy or sputum cytology. The biopsy procedure with 18-gauge Crown needle was guided by fiuoroscopy. The biopsy specimen placed in 10% formalin solution were histologically confirmed.
RESULTS
In 160 patients(89%), the positive diagnosis was made by percutaneous needle aspiration biopsy. There were 153 lung lesions(120 malignant and 33 benign lesions) and 7 mediastinal lesions. the diagnostic accuracy of malignant and benign disease was 91% and 80% respectively. Complications included pneumothorax(n=11) and hemothorax(n=l):six of them required treatment with chest tube and the remainder showed spontaneous resporption.
CONCLUSION
PCNB with an 18-gauge needle provided a reliable, relatively safe diagnostic tool to establish the diagnosis of both malignant and benign chest lesions.
