Abstract
|
|
|
Percutaneous needle biopsy is most reliable noninvasive method of obtaining the confirm diagnosis of peripheral pulmonary nodule. Needle aspiration combined with cytologic examination is being used with increasing frequency in the diagnosis of
pulmonary
nodules and masses. Percutaneous needle lung biopsy was bone in pulmonary or mediastinal lesions using 19 Gauge fine aspiration needle or 14 Gauge cutting needle, and the results were compared with respect to diagnostic accuracy and complications
Over a periods of recent ten years, 476 patients who had localized pulmonary lesion sand underwent percutaneous needle lung aspiration and biopsy using 19 Gauge fine aspiration needle or 14 Gauge cutting needle.
The age distribution of the patients was from sixteen to eighty-one years old. Among 467 patients, 337 patients were male and 130 patients were female. In 244 patients, the lesion were less than 4cm in largest diameter, and in 223 patients, the
lesion
were larger than 4cm, but the size of the lesion was not correlated with malignancy. Diagnosic yields of the 14 Gauge cutting needle and the 19 Gauge fine needle were 88.3% and 76.8% respectively. Success rate of benign and malignant lesion were
more
higher in 14 Gauge cutting needle than 19 Gauge fine aspiration needle. Common diseases were primary lung cancer, tuberculoma, abscess in order of frequency. The complications of procedure ware mild pneumothorax in ten patients, mild hemoptysis
in
six
patients and subcutaneous emphysema in one patients. With Cutting needle and aspiration needle, complication rate were 2.73% and 1.36%, respectively.
Percutaneous needle lung biopsy with cutting needle under the chest computed tomogram and biplane fluroscopy had lower complication rate and high diagnostic success rate for the intrathoracic lesions.
