[Transbronchial needle aspiration under CT guide for enlarged mediastinal lymph node biopsy].
To ascertain the nature of enlarged mediastinal lymph nodes transbronchial needle aspiration (TBNA) was performed under CT guide through bronchoscopy. Forty-five enlarged mediastinal lymph nodes from 33 lung cancer patients were biopsied. The results indicated that 25 enlarged lymph nodes from 20 patients were due to cancer metastasis while 15 enlarged lymph nodes from 8 cases were due to inflammation, and those from the remaining 5 cases were normal. Therefore, about 33.3% of the enlarged mediastinal lymph nodes in lung cancer patients result from noncancerous inflammatory changes. TBNA under CT guide has the advantage of accurate localization, is easy to perform and safe.
