    • Abstract

    Background
    Ultrathin bronchoscopes can be guided under fluoroscopy to reach solitary pulmonary nodules. The aim of this study is to compare its diagnostic yield against conventional bronchoscope.

    Methods
    two hospitals have prospectively collected patients referred to study solitary pulmonary nodules by bronchoscopy under fluoroscopy guidance. One centre performed the procedures with a conventional bronchoscope (Olympus BF Q-180, outer diameter 5.5 mm, working channel 2.0mm) and the other an ultrathin (Olympus XP 160, outer diameter 2.8; working channel 1.2 mm). In both groups bronchial washings were routinely collected. In the conventional group, brushing was always performed and biopsies were performed only when biplane fluoroscopy confirmed that forceps were in contact with the lesion. In the ultrathin bronchoscope group, biopsies were only performed when an endoluminal lesion was seen; if there were no endobronchial lesion, then bronchial brushing was performed.

    Results
    both groups were similar in the main variables, except for the number of brushes performed in the conventional group (total 31 vs. 66; p <0.05)). Conventional (n=27): age 67.6; gender (M) 66.7%; diameter 20.1 (SD 5.9); SUVm (n=20) 9.1; localization 0% (inner), 50% (middle), 50% (outer); left lower lobe (11.1%), bronchus sign (45%); visualized by fluoro (88.9%); biopsy performed (40.9%); brushes (2 in 55%, 3 in 44.4%). Ultrathin (n=39): age 66.9; gender (M) 79.5%; diameter 21.5 (SD 6.0); SUVm (n=32) 7.7; localization 11.1 (inner), 55.6% (middle), 33.3% (outer); left lower lobe (12.8%), bronchus sign (68.4%); visualized by fluoro (69.2%); biopsy performed (59.1%); brushes (non2 20%, 1 in 69.2%, 2 in 7.5%%, 3 in 2.6%). The final diagnosis were achieved in 44.4% in the conventional group vs. 38.5% in the ultrathin group (p=0.6)

    Conclusion
    the ultrathin bronchoscope is equally effective as the conventional bronchoscopy under fluoroscopy guidance in the diagnosis of SPN.
