Se estudia la posible utilidad de la punción bronquial aspirativa a través del broncofibroscopio en 125 neoplasias localizadas en bronquios centrales accesibles a la visión endoscópi-ca. En todos los casos, la imagen endobronquial sugería la posible negatividad de la biopsia, el legrado y el broncoaspirado debido a: 1) crecimiento peribronquial del tumor o 2) masa endobronquial difícil de biopsiar de forma eficaz a causa de necrosis, carácter hemorragíparo o difícil acceso. En ambas circunstancias, la adición de la punción a las demás técnicas aumentó de forma significativa el rendimiento diagnóstico de la broncoscopia: del 72% al 83% (p < 0,05) en los 78 tumores de crecimiento peribronquial y del 70% al 87% (p < 0,025) en las 47 masas endobronquiales. Estos resultados confirman la utilidad de la punción bronquial aspirativa en el diagnóstico de las neoplasias bronquiales centrales con imagen endoscópica que haga sospechar la negatividad de otras técnicas.

In 125 neoplasms localized at the central bronchi and visually accessible at endoscopy, the usefulness of transbronchial needle aspiration through the fiberoptic bronchoscopy was evaluated. In all cases the endobronchial observation suggested that the biopsy or bronchoaspirate will not be successful in obtaining specimen because: a) the tumor showed a periobronchial growing, or b) the endobronchial mass exhibited necrosis, hemorrhage or a difficult access. In both circumstances aspirative punction increased the diagnostic yield of bronchoscopy: from 72% to 83% (p<0,05) in the 78 tumors of peribronchial growing and from 70% to 87% (p<0,025) in the 47 endobronchial tumors. These results confirm the usefulness of transbronchial needle aspiration in the diagnosis of central bronchial neoplasms in which endoscopio observation suggests that the other techniques will have important limitations.
