Abstract		Background. The results of bronchoscopic needle aspiration (BNA) used to confirm the spread of metastases from lung lung cancer to the mediastinal lymph nodes were compared with histopathological findings at surgical resection. The diagnostic yield of BNA of peripheral lymph nodules and mases, and of peribronchial and submucosal lesions was assessed in two groups of patients. Methods. In this retrospective study, we compared the results of BNA and operative histological findings in 28 patients with lung cancer. In addition, we determine dthe diagnostic yield of BNA in 26 patients with peripheral lymph nodes involvement, and in 24 patients with peribronchial and submucosal malignant lesions. The latter two groups were evaluated both by BNA, transbronchial biopsy, bronchial biopsy and transthoracic aspiration needle biopsy. Results. BNA demonstrated malignant cells in 2 patients, while staging done by the pathologist revealed metastase to mediastinal lymph nodes in 8 patients. In our group, the positive and negative predictive value of BNA was 100% and 78%, respectively. The diagnostic yield of BNA was 54% forpatients with peripheral lesions, and 63% for patients with signs of peribronchial and submucosal involvement. Conclusions. BNA has a high positive predictive value in staging lung cancer concerning the mediastinal lymph node involvement. Also, it a useful adjunct method in the diagnosis of peripheral lymph mode and peribronchial and submucosal lesions.
Summary		Izvleček. Bronshoskopska igelna aspiracija (BIA) je učinkovita dodatna metoda v invazivni pljučni diagnostiki. glavne indikacije so zamejitev pljučnega raka glede na zaseženost bezgavk mediastinuma, vtisnjenje dihalnih poti zaradi peribronhialne rašče, submukozna rast tumorja in periferne spremembe. Bolniki in metode. V retrospektivni študiji smo pri 28 bolnikih s pljučnim rakom primerjali izvid BIA in končni patološki izvid pri operaciji. V dveh dodatnih skupinah bolnikov smo ugotavljali, kakšna je bila diagnostična uspešnost BIA pri perifernih spremembah - 26 bolnikov in pri spremembah v velikih dihalnih poteh (submukozna rast procesa in znaki pritiska na bronhije zaradi peribronhialne rašče) - 24 bolnikov. Rezultati. Pred operacijo smo ugotovili zaseženost bezgavk v mediastinumu pri dveh bolnikih, ob operaciji pa pri osmih. Pozitivna napovedna vrednost BIA pri naših bolnikih je bila 100%, negativna pa 78%. Primerjali smo tudi diagnostično uspešnost BIA pri bolnikih s periferno lezijo, kjer je bila diagnostična pri 54% in pri bolnikih z znaki vtisnjenja bronhijev in submukozne rasti, kjer je bila BIA diagnostična pri 63% bolnikov. Zaključki. BIA ima visoko pozitivno napovedno vrednost pri zamejitvi pljučnega raka glede zaseženosti bezgavk mediastinuma, in je dopolnilna diagnostična metoda pri diagnostiki perifernih lezij in sprememb v velikih dihalnih poteh.
