Abstract

The aim of the present study was to determine the indications for radial endobronchial ultrasound‑guided transbronchial lung biopsy (rEBUS‑D‑TBLB) for the diagnosis of peripheral pulmonary lesions (PPL) located at the bronchopulmonary segments and subsegments. Data collected from 774 patients who underwent rEBUS‑D‑TBLB for suspected PPL, including clinical information, distribution of lesions, diagnostic spectrum and diagnostic rate, were collected and retrospectively reviewed. Additionally, the Wilcoxon signed‑rank test was performed to analyze the diagnostic yield of lesions in bronchopulmonary subsegments under the lesion diameter limit of 3 cm. In total, 802 lesions were found in 774 patients. The diagnostic yield of rEBUS‑D‑TBLB for all lesions was 67.18%. Overall, 362 cases of malignant disease and 158 cases of benign disease were diagnosed, with sensitivities of 70.98 and 79.00% respectively. Lesions were distributed throughout the 18 bronchopulmonary segments of the lungs. The bronchopulmonary segments with >5% of the majority of the discovered lesions were LB1+2, LB3, LB6, LB10, RB1‑4 and RB9. The diagnostic yield of rEBUS‑D‑TBLB was found to be >65% for lesions located at LB3, RB1‑3 and RB9. Further rEBUS‑D‑TBLB examinations of the LB1+2a, LB6a and RB4b segments produced diagnostic yields of 81.25, 66.67 and 71.43% respectively. Finally, at segment RB4a, rEBUS‑D‑TBLB examination was more effective for lesions with diameters >3 cm compared with lesions with diameters <3 cm. The diagnostic yields for PPL distributed at LB1+2a, LB3, LB6a, RB1‑3, RB4a (diameter >3 cm), RB4b, and RB9 using rEBUS‑D‑TBLB were higher compared with for other segments, providing a theoretical basis for the clinical application of rEBUS‑D‑TBLB for the diagnosis of PPL in patients.
