Phase II study of endobronchial ultrasound (EBUS)-guided transbronchial biopsy using thin bronchoscope (XBF-3B260Y1) with miniature probe (XUM-S20-17R) for diagnosis of peripheral pulmonary lesions - EBUS-guided transbronchial biopsy using thin bronchoscope with miniature probe

A total of 86 patients with suspected peripheral lesions were included in this prospective study. Twelve patients with endobronchial lesions within the segmental bronchi and 3 patients who did not return to follow-up were excluded from this analysis. Thus, a total of 71 patients with peripheral pulmonary lesions (mean size, 31.2 +- 12.7 mm) were included in the final analysis. The mean bronchus level reached with the thin bronchoscope was 4.6 generations. Diagnostic histologic specimens were obtained in 49 of 71 patients (69%: 80% for malignant lesions and 52% for benign lesions). There were no significant complications.
