Metagenomic next-generation sequencing diagnosis of peripheral pulmonary infectious lesions through virtual navigation, radial EBUS, ultrathin bronchoscopy, and ROSE

| Summary: | Objective To evaluate the efficacy of combined rapid on-site evaluation of cytology (ROSE), ultrathin bronchoscopy, virtual bronchoscopic navigation, radial endobronchial ultrasound (EBUS), and metagenomic next-generation sequencing (mNGS) for diagnosis of peripheral pulmonary infectious lesions. Methods Specimens from patients with peripheral lung infection were obtained by transbronchial lung biopsy (TBLB) and bronchoalveolar lavage (BAL), and mNGS was used to detect pathogenic microorganisms. The sensitivity and specificity of mNGS were compared between TBLB tissue and BAL fluid. Results The most common pathogens of pulmonary infectious lesions in this study were Pseudomonas aeruginosa , Klebsiella pneumoniae , and Acinetobacter baumannii . The specificity of mNGS was higher in TBLB tissue than in BAL fluid, but mNGS of BAL fluid had higher sensitivity. Conclusions The combination of ROSE, ultrathin bronchoscopy, virtual bronchoscopic navigation, radial EBUS, and mNGS technology yielded high efficacy for the diagnosis of peripheral pulmonary infectious lesions. TBLB and BAL specimens have respective advantages in specificity and sensitivity for mNGS analysis. |
