Lung tissue pathology includes wide range of diseases, for specific treatment pathology confirmation is needed. Transbronchial lung biopsy is the one of the ways to obtain the material. Aim of our investigation was to assess efficacy and the level of complication associated with this procedure. Materials and methods. Results of 201 transbronchial lung biopsy performed from 2014 to 2016 were analyzed. Manipulation performed in endoscopy department under fluoroscopy control and radiologist superwising. Results. Diagnostic yield was 87,6%. The most common histology patterns were sarcoidosis and pneumonitis. Pneumothorax rate was 1 %, bleeding - 1 %. There were no procedure-related deaths. Conclusion. Transbronchial lung biopsy is a safe and effective method for lung tissue pathology confirmation with relatively low risk of complications.
