Efficacy and safety of radial probe endobronchial ultrasound-guided biopsy for peripheral lung lesions in chronic obstructive pulmonary disease patients

RP-EBUS-TBLB can be used as an appropriate method to diagnose PPLs in patients with COPD. The size of the lesion (≥30 mm) and having the probe within the lesion were important for successful diagnosis. The location of the lesion in the upper lobe is associated with diagnostic failure. No difference was observed in the diagnostic yield based on the severity of airflow limitation. The complication rates were acceptable.
