[Endoscopic diagnosis of tuberculosis and other granulomatous diseases of respiratory organs: advances and prospects].

The paper presents data on the use of various bioptic methods in phthisiatry and pulmonology. Particular attention is given to granulomatous diseases of the lung whose misdiagnosis may be during clinical examinations in 50-70% of cases. Making the methods of transbronchial biopsies, including those of the lung and bronchoalveolar lavage, better, putting them into practice widely, and developing new studies (microbiological, electron microscopic, immunological, morphological) for biopsy specimens may improve the diagnosis of lung diseases.
