  • Title: [Transbronchial lung biopsy as a diagnostic method of peripheral lesions].

    Abstract:
    The aim of the study was to assess the diagnostic yield of transbronchial lung biopsy (TBLB) without fluoroscopic guidance in peripheral lesions of diameter 2,5-6 cm. TBLB was performed in 65 consecutive patients without abnormalities in bronchial tree in standard bronchofiberoscopy and preceded by computed tomography (CT). The CT guidance helped to select the segment of lung to be biopsied. In 39 patients (60%) TBLB enabled to diagnose 36 cases of lung cancer, 2 cases of carcinoid and 1 case of malignant lymphoma. There were 26 cases (including 21 cases of lung cancer) undiagnosed by means of TBLB. In 24 patients the diagnosis was established by means of other methods like transbronchial needle aspiration (TBNA)--5 cases, thin needle biopsy (TNB)--12 cases, open lung biopsy (OLB)--7 cases and in the remaining 2 patients a regression of clinical and radiological features was observed. Transbronchial lung biopsy was found to be efficient diagnostic method in peripheral lesions higher than 2,5cm. However, in 40% of cases this technique doesn't allow to establish a diagnosis. This, in turn implicates the necessity for further diagnostic procedures including TBNA, TNB or even OLB.
