[A stereoscopic localization apparatus for early diagnosis of lung cancer and its clinical application].
We invented a stereoscopic localization apparatus for early diagnosis of lung cancer, facilitating fine needle aspiration biopsy especially for the deep-situated small lesion of the lung. Under X-ray, the stereoscopic localization of the three dimensions, posteroanterior sagittal and frontal plane, and transverse section of the body with small lesions can be soon established accurately with the apparatus. 227 percutaneous aspiration biopsies of lung lesions were performed by using the apparatus from 1985 to 1989. Of the 206 patients, 180 had lung lesions less than 3cm in size, and in 89.6% of the patients positive diagnosis was obtained by the first puncture biopsy. Satisfactory specimens were obtained in 96.6% of the biopsies. 26 malignant lesions about 1cm in diameter were localized, punctured and diagnosed accurately. They were subsequently confirmed surgically and pathologically. Mild pneumothorax occurred in 19 patients, and it subsided spontaneously.
