Late Breaking Abstract - Efficacy of radial EBUS with thin bronchoscope in patients with peripheral pulmonary lesions

This study investigate the effectiveness of radial endobronchial ultrasound – transbronchial biopsy (R-EBUS-TBB) with thin bronchoscope in peripheral lung lesions. We compared the diagnostic yields and complication rates of REBUS-TBB with CT-PTNB in a total of 199 patients with peripheral lung lesions. Of the total 199 men, 120 were men and the mean age was 67.6 ± 12.5 years. The left upper lobe was 61 (30.7%) and right upper lobe was 59 (29.6%). 68.8% of the 137 confirmed cases were diagnosed as malignant. The diagnotic accuracy of R-EBUS-TBB in 56 patients was lower than CT-PTNB in 179 patients with statistically significant difference (64.3 vs. 85.9%; P <0.001). Of these, 14 were performed with R-EBUS-TBB alone, 146 with CT-PTNB only, and 43 with simultaneously R-EBUS-TBB and CT-PTNB. There was no difference in the diagnostic yield of three groups; 85.7% of R-EBUS alone, 87.7% of CT-PTNB only, and 95.3% of combined CT-PTNB and R-EBUS. In the 56 patients who underwent R-EBUS, the diagnosis rate according to the location of the tumor in the ultrasonic probe had significant difference. Complications in CT-PTNB were pneumothorax in 60 patients (32.4%), bleeding in 13 patients (7.0%), pneumonia in two patients (1.1%), while R-EBUS had a moderate cough in four patients (7.1%). The diagnosis rate of R-EBUS-TBB was lower than that of CT-PTNB, but it was very safe and showed a high diagnostic yield of 85.7% in patients with difficult access by CT-PTNB
