Se realiza un estudio sobre 156 pacientes con imagen radiológica única de nodulo pulmonar solitario (NPS) que fueron diagnosticados de carcinoma broncogénico (CB), con el fin de relacionar la posición radiológica del tumor con la rentabilidad diagnóstica de la fibrobroncoscopia (FB). Para la localización radiológica del tumor se utilizó un método de división pulmonar con el fin de delimitar dos zonas: central y periférica. Este método está basado en el campo de máxima visualización al fibrobroncoscopio del árbol bronquial. La FB se realizó en todos los casos sin fluoroscopia. En los NPS de localización central, el porcentaje diagnóstico de la FB fue del 89,6% (78/ 87) descendiendo al 34,8% (24/69) en los de localización periférica con una diferencia estadísticamente significativa entre ambos grupos de p < 0,001.

A la vista de los resultados obtenidos, concluimos que el sistema de clasificación radiológica que hemos utilizado tiene una gran validez y por ello, así como por la baja rentabilidad de la FB en los tumores periféricos, debería de ser aplicado sistemáticamente a todos aquellos pacientes con un NPS a fin de elegir la técnica diagnóstica más adecuada en cada caso, sin necesidad de recurrir para ello a una FB previa.

In order to assess the relationship between the radiographic location of tumours and the diagnostic effectiveness of fiberoptic bronchoscopy (FB), we studied 156 patients with the only radiographic finding of a sole pulmonary node (NPS) diagnosed as bronchogenic carcinoma (CB). For radiographic location of every tumour, the pulmonary fields were divided in two areas: central and peripheral. This method is based on the maximum visualization scope of the bronchial tree by using fiberoptic bronchoscopy. Bronchoscopy was ahvays performed without fluoroscopy. The diagnostic rates were 89.6% (78/87) for centrally located pulmonary nodes and 34.8% (24/69) for nodes of peripheral location. That difference is statistically significant at p < 0.001.

Based on the results obtained in this study we conclude that the radiographic classification we used is highly effective. For that reason, as well as for the low diagnostic effectiveness of fiberoptic bronchoscopy in peripheral tumours, it should be used systematically in every patient with a sole pulmonary node in order to select the adequate diagnostic procedure in every case without the need for a previous fiberoptic bronchoscopy examination.
