[Bronchofibroscopic and histological studies in the differential diagnosis of interstitial lung diseases in children].

The examination of 51 children with lung diseases revealed a great variety of their forms. While choosing the optimum method of early diagnosis of interstitial lung disease in children, it is necessary to use all currently available techniques: X-ray, tomography, scintigraphy, lung function tests, laboratory analyses, and morphological study of specimens of transbronchial lung biopsy and alveolar lavage (AL). In the authors' opinion, fibroscopy with transbronchial lung biopsy and lung are major techniques of differential diagnosis of pediatric pulmonology.
