The role of transbronchial lung biopsy in the diagnosis of solitary pulmonary nodule.
Transbronchial lung biopsy (TBLB) is a well-recognized diagnostic technique in diffuse interstitial lung diseases, but it is not considered to be the first choice in investigation of solitary pulmonary nodules (SPN). The main idea of this study was to increase the sensitivity of bronchoscopy using multiple techniques, especially TBLB, thus to avoid more aggressive diagnostic procedures. The objective of this prospective study was to evaluate the efficacy and safety of TBLB in the diagnosis of SPN, in comparison with other bronchoscopic techniques. ⋯ Diagnostic yield improved significantly with the increasing number of specimens (less than 3 specimens: sensitivity 59%, 3 or more specimens: sensitivity 87%, p < 0.05). Complications of TBLB occurred in 2 (4%) patients: 1 incomplete pneumothorax and 1 hemorrhage. According to the results, we conclude that TBLB is an accurate and safe technique for the diagnosis of pulmonary solitary nodule with a diameter equal or greater than 25 mm.
