[Transthoracic puncture biopsy in the diagnosis of peripheral lung neoplasms].

Transthoracic puncture biopsy of the lung using an original procedure of application of an unsophisticated trocar was performed in 109 patients with peripheral neoplasms. The procedure was carried out by a surgeon and a roentgenologist and was monitored by means of the TYP-DE-800 TV installation provided with an electronic optical amplifier. Peripheral cancer was identified in 83 cases, metastases of tumors which arose at sites other than the lung--7; chronic abscess--8 and benign lesions in 11 cases. Owing to its high diagnostic value and safety, a wide-scale application of vacuum biopsy should be recommended in cases of peripheral pulmonary neoplasms (segmental and subsegmental) of uncertain etiology.
