LOCALIZATION AND SHAPE OF STENOSES IN CENTRAL LUNG CARCINOMA- SENSITIVITY AND PRECISION OF MDCT VB AND FB/LOKALIZACIJA I OBLIK STENOZA U CENTRALNOM KARCINOMU PLUCA--OSJETLJIVOST I PRECIZNOST MDCT VB I FB

The objective is to present diagnostic capabilities of virtual bronchoscopy (VB) and fiberoptic bronchoscopy (FB) for determining the localization and shape of stenoses in patients with central lung carcinoma. A systematic study was performed on 220 patients aged 11-83 (54.36[+ or -]17.24) years with endobronchial disease using the FB and VB methods during the 2013-2017 period. Central carcinoma of the lung was found on VB in 130 patients and on FB in 120 patients. Other nosologic diseases were found in 22 patients. Right localization of central carcinoma prevailed over left localization in both sexes. A significant difference in the localization criterion was found in female patients examined by VB (U-test, p=0.01). VB and FB yielded 86.5% vs. 91.60% precision and 85% vs. 94.5% sensitivity. In conclusion, VB was found to be a successful noninvasive method for determining the localization of lung tumors and shape of stenoses, which are essential in the diagnosis of malignant processes.

Sustavna studija provedena je na 220 bolesnika u dobi od 11 do 83 godine (54,36[+ or -]17,24) s endobronhijalnom bolesti primjenom metoda FB i VB u razdoblju od 2013. do 2017. godine. Središnji karcinom pluca otkriven je na VB u 130 bolesnika i na FB u 120 bolesnika. U 22 bolesnika pronadene su druge nozološke bolesti u oba spola. Desnostrana lokalizacija prevladavala je nad lijevostranom lokalizacijom središnjeg karcinoma. Znacajna razlika u kriteriju lokalizacije pronadena je u žena koje su pregledane pomocu VB (U-test, p=0,01). Preciznost VB bila je 86,5% prema 91,60% za FB, dok je osjetljivost VB bila 85% u usporedbi s 94,5% za FB. Zakljuceno je da je VB uspješna neinvazivna metoda za odredivanje lokalizacije tumora pluca i oblika stenoza, koji su neophodni u dijagnostici zlocudnih procesa.
