În lucrare sunt analizate datele cercetărilor endoscopice ale bronhiilor mari şi mici la 153 de bolnavi cu tuberculoză evolutivă. Afectarea bronhiilor mari s-a înregistrat la 96 (62,7%) de bolnavi. Dereglările respiraţiei s-au constatat la 57 (59%) de bolnavi. Simptomatologia endoscopică a bronhiilor mici este mult mai numerică. În total la cei 153 de bolnavi s-au vizualizat 1071 de diferite caractere endoscopice. La fiecare bolnav cu indicii normali ai spirogramei reveneau câte 7,4 caractere endoscopice. Astfel, cu mult până la apariţia dereglărilor spirometrice, în bronhiile mici se produc leziuni acute şi se formează leziuni postinflamatorii. S-a stabilit importanţa cercetărilor endoscopice a bronhiilor mici, care elucidează leziuni morfologice la 100% de cazuri.

In this study were analyzed results of small and big bronchi endoscopic investigations in 153 patients with advanced tuberculosis. Big bronchi’s affection was observed in 96 patients (62,7%), changes in pulmonary functional tests were revealed in 57 (59%) patients. Endoscopic simptomatology of small bronchi was more numerical: in total in 153 patients there were visualized 1071 different pathological endoscopic characteristics. There were revealed at mean 7,4 pathological endoscopic characteristics in every patient with normal parameters of pulmonary functional tests. Thus, there were determined, that long before pulmonary functions tests changes appearance, in small bronchi produced acute lesions and formed inflamatory injury. There were stated the importance of small bronchi endoscopic investigation, that detected morphologic lesions in 100% of cases.
