    • Abstract

    Background
    Flexible fiberoptic bronchoscopy (FB) is the standard of care for the evaluation of pulmonary lesions. The aim of the current study is to investigate the effectiveness of EBUS-guided bronchoscopy compared to blind FB techniques in the study of non-visible pulmonary lesions.

    Methods
    We conducted a one year, retrospective, study comparing two populations: In the first one biopsies were performed conventionally (FB-B) with the help of static CT images and in the second biopsies were performed after EBUS- guidance (FB-EBUS). A 20- MHz radial- type ultrasound probe was used to obtain images. Sampling techniques, like bronchial brushing (BR) and transbronchial biopsies (TBB), were conducted in both populations by two separate bronchoscopists. If not a diagnosis was achieved a surgical biopsy or observation strategy was followed.

    Results
    Forty patients appeared with non visible lesions and were included in this study. Twenty patients were examined with the use of EBUS (FB- EBUS) and in twenty cases a conventional FB (FB-B) was conducted. Moreover left lower lobe was the most promising to obtain a diagnosis using ultrasonographic images.

    Conclusion
    Our results suggest that in patients with a non visible pulmonary lesion or SPNs a diagnostic strategy involving EBUS- guided biopsy techniques is a reasonable and effective choice.
