[Methodology and effectiveness of bronchoscopy with polychromatic analysis in patients with pulmonary tuberculosis and sarcoidosis].

A procedure of polychromatic analysis (PA) was improved by using light filter occular attachments. In 154 patients, including those with pulmonary tuberculosis (101) and sarcoidosis (53), a diagnostic effectiveness of a traditional bronchoscopy is compared to that with PA, including morphoendoscopic comparison. As against traditional bronchoscopy, PA made it possible to find out in 34.8% an additional number of non-specific endobronchitis cases accompanying pulmonary tuberculosis, and at the same time to approach in 90.2% an endoscopic diagnosis to a pathomorphologic one. In several patients the authors managed to additionally distinguish by means of PA infiltrative bronchial tuberculosis of tuberous type. In pulmonary sarcoidosis the use of PA also allowed to increase a diagnostic effectiveness of the traditional bronchoscopy.
