Diagnosis of small pulmonary lesions by transbronchial lung biopsy with radial endobronchial ultrasound and virtual bronchoscopic navigation versus CT-guided transthoracic needle biopsy: A systematic review and meta-analysis.

ABSTRACT: Advances in bronchoscopy and CT-guided lung biopsy have improved the evaluation of small pulmonary lesions (PLs), leading to an increase in preoperative histological diagnosis. We aimed to evaluate the efficacy and safety of transbronchial lung biopsy using radial endobronchial ultrasound and virtual bronchoscopic navigation (TBLB-rEBUS&VBN) and CT-guided transthoracic needle biopsy (CT-TNB) for tissue diagnosis of small PLs.A systematic search was performed in five electronic databases, including MEDLINE, EMBASE, Cochrane Library Central Register of Controlled Trials, Web of Science, and Scopus, for relevant studies in May 2016; the selected articles were assessed using meta-analysis. The articles were limited to those published after 2000 that studied small PLs ? 3 cm in diameter.From 7345 records, 9 articles on the bronchoscopic (BR) approach and 15 articles on the percutaneous (PC) approach were selected. The pooled diagnostic yield was 75% (95% confidence interval [CI], 69-80) using the BR approach and 93% (95% CI, 90-96) using the PC approach. For PLs ? 2 cm, the PC approach (pooled diagnostic yield: 92%, 95% CI: 88-95) was superior to the BR approach (66%, 95% CI: 55-76). However, for PLs > 2 cm but ? 3 cm, the diagnostic yield using the BR approach was improved to 81% (95% CI, 75-85). Complications of pneumothorax and hemorrhage were rare with the BR approach but common with the PC approach.CT-TNB was superior to TBLB-rEBUS&VBN for the evaluation of small PLs. However, for lesions greater than 2 cm, the BR approach may be considered considering its diagnostic yield of over 80% and the low risk of procedure-related complications.

Project description:BACKGROUND:Radial endobronchial ultrasound (R-EBUS) transbronchial lung biopsy (TBLB) improves the diagnostic yield from peripheral pulmonary lesions (PPLs). However, the small specimens obtained using small forceps through a guide sheath (GS) may impede diagnosis and molecular analysis. Here, we investigated the diagnostic significance of additional conventional TBLB with standard forceps after R-EBUS-GS-guided TBLB. METHODS:We retrospectively reviewed data from 55 patients who underwent conventional TBLB after R-EBUS-GS-guided TBLB for PPL diagnosis. Procedures were performed on single PPLs with no visible lesions on bronchoscopy. In cases with inconclusive pathologic confirmation, final diagnoses were made based on pathologic specimens or clinical observations. RESULTS:The median size of the target lesions was 28?mm. The appearances on computed tomography images were solid (n = 45, 81.8%), part-solid (n = 7, 12.7%), and cavitary nodules (n = 3, 5.5%). A computed tomography bronchus sign was present in 35 (63.6%) cases, and a radial probe was positioned within target lesion in 32 (58.2%) cases. R-EBUS-GS-guided TBLB was diagnostic in 30 (54.5%) patients, and subsequent conventional TBLB yielded additional diagnostic information in 8 (14.5%) patients. Probe positioning within target lesions and the outer margin of PPLs more than 1 cm from pleura were significantly associated with enhanced diagnostic yield from the combined procedures. In conventional TBLB, probe positioning within target lesions (75.0% vs. 11.8%, P = 0.004) and characteristic of nonsolid nodules (83.3% vs. 15.8%, P = 0.006) were significantly associated with additional diagnostic utility. CONCLUSIONS:Conventional TBLB following R-EBUS-GS-guided TBLB could be a useful procedure for diagnosing PPLs, especially for nonsolid nodules. KEY POINTS:Significant findings of the study: Additional conventional TBLB with standard forceps after R-EBUS-GS-guided TBLB yielded an additional 14.5% diagnostic utility for peripheral pulmonary lesions. For conventional TBLB, probe positioning within target lesions and nonsolid nodules were significantly associated with additional diagnostic utility. WHAT THIS STUDY ADDS:Conventional TBLB with standard forceps after R-EBUS-GS-guided TBLB is an effective and economically accessible diagnostic tool for peripheral pulmonary lesions.

Project description:Background:Metagenomic next-generation sequencing (mNGS) is a new technology that allows for unbiased detection of pathogens. However, there are few reports on mNGS of lung biopsy tissues for pulmonary infection diagnosis. In addition, radial endobronchial ultrasound (R-EBUS) is widely used to detect peripheral pulmonary lesions (PPLs), but it is rarely used in the diagnosis of peripheral lung infection. Objective:The present study aims to evaluate the combined application of R-EBUS-guided transbronchial lung biopsy (TBLB) and mNGS for the diagnosis of peripheral pulmonary infectious lesions. Methods:From July 2018 to April 2019, 121 patients from Tianjin Medical University General Hospital diagnosed with PPLs and lung infection were enrolled in this prospective randomized study . Once the lesion was located, either TBLB or R-EBUS-guided-TBLB was performed in randomly selected patients, and mNGS was applied for pathogen detection in lung biopsy tissues. The results of mNGS were compared between the TBLB group and R-EBUS-guided TBLB group. In addition, the clinical characteristics and EBUS images from 61 patients receiving bronchoscopy for peripheral lung infectious detection were analyzed and compared with the results of mNGS. Results:The positivity rate of mNGS in R-EBUS-guided TBLB was (78.7%, 48/61) that was significantly higher than (60.0%, 36/60) in the TBLB group. Difference in the position of R-EBUS probe and image characteristics of peripheral lung infectious lesions affected the positivity rate of mNGS. Tissue collected by R-EBUS within the lesion produced higher positivity rate than samples collected adjacent to the lesion (P=0.030, odds ratio 17.742; 95% confidence interval, from 1.325 to 237.645). Anechoic areas and luminant areas of ultrasonic image characteristics were correlated with lower positivity rate of mNGS (respectively, P=0.019, odds ratio 17.878; 95% confidence interval, from 1.595 to 200.399; P=0.042, odds ratio 16.745; 95% confidence interval, from 1.106 to 253.479). Conclusions:R-EBUS-guided TBLB is a safe and effective technique in the diagnosis of peripheral lung infectious lesions. R-EBUS significantly facilitates the accurate insertion of bronchoscope into the lesions, which improves positivity rate of mNGS analysis in pathogen detection. The R-EBUS probe position within lesion produced a higher positivity rate of mNGS analysis. Nevertheless, the presence of anechoic and luminant areas on ultrasonic image was correlated with poor mNGS positivity rate.
