Abstract Background: Cryobiopsy is an established technique that yields larger and higher-quality samples than does a forceps biopsy. However, it remains underutilised in the diagnosis of peripheral pulmonary lesions (PPLs), mainly because of difficulties in handling conventional cryoprobes. A recently introduced single-use cryoprobe with a smaller diameter and more flexibility than conventional ones may improve its diagnostic ability for PPLs. We conducted this prospective study to evaluate the feasibility of transbronchial cryobiopsy in the diagnoses of PPLs, using a new 1.7-mm cryoprobe. Methods: The study included patients with PPLs less than 30 mm in diameter scheduled to undergo bronchoscopy. All the procedures were performed using a combination of virtual bronchoscopic navigation, radial endobronchial ultrasound (R-EBUS) and X-ray fluoroscopy, and all the samples were collected using the cryoprobe alone. Thereafter, we assessed the diagnostic outcomes and safety profiles.Results: A total of 50 patients were enrolled and underwent cryobiopsy. The median lesion size was 20.8 mm (range, 8.2–29.6 mm), and the negative bronchus sign was seen in 34% of lesions. The diagnostic yield was 94% (95% confidence interval, 83.5–98.8%). A positive bronchus sign had a significantly higher diagnostic yield than did a negative bronchus sign (100% vs. 82.4%; P=0.035). The yield was achieved regardless of other variables, including lesion size, location, and R-EBUS findings. The major complications were mild and moderate bleeding in 28% and 62% of patients, respectively. Pneumothorax was identified in one patient.Conclusion: Transbronchial cryobiopsy using the new 1.7-mm cryoprobe is a feasible procedure that has the potential to increase the diagnostic accuracy for PPLs.Trial Registration: Japan Registry of Clinical Trials, jRCT1032200065.

The aim of the study was to determine the accuracy of rapid on-site examinations, performed on transbronchial brushings of peripheral pulmonary lesions, in determining final bronchoscopic diagnosis. In addition to determining if rapid on-site examination impacts procedural outcomes.A prospective cohort study of consecutive patients with peripheral pulmonary lesions, which had been located by radial endobronchial ultrasound, was undertaken. Bronchoscopy was terminated if rapid on-site examination demonstrated diagnostic malignant material. Non-diagnostic rapid on-site examination resulted in further bronchoscopic sampling, including transbronchial lung biopsy and/or sampling from different locations.128 peripheral pulmonary lesions were located by endobronchial ultrasound in 118 patients. The final bronchoscopic diagnoses included nonsmall cell lung cancer (n=76), carcinoid (n=3), and metastatic malignancy (n=3). Procedure times were significantly shorter for procedures when rapid on-site examinations demonstrated malignancy compared to those where rapid on-site examination was non-diagnostic (19±8 min versus 31±11 min, respectively; p<0.0001). In four procedures, initial negative rapid on-site examination results prompted redirection of sampling from alternate bronchial segments, resulting in positive diagnostic tissue being obtained. Positive and negative predictive value of rapid on-site examination for a malignant bronchoscopic diagnosis was 63 (97%) out of 65, and 43 (68%) out of 63, respectively.Rapid on-site examination of brushing specimens has a very high, positive, predictive value for bronchoscopic diagnosis of cancer and shortens the bronchoscopy procedure times. It has the potential to reduce complications, improve cost-effectiveness, and may improve diagnostic performance via live feedback.

Objective: To evaluate the diagnostic value of radial endobronchial ultrasound (R-EBUS) combination with rapid on-site evaluation (ROSE) guided transbronchial lung biopsy (TBLB) for peripheral pulmonary lesions. Methods: Peripheral pulmonary lesions identified by computed tomography underwent R-EBUS with or without ROSE randomly from February 2016 to August 2017. The diagnostic yield and the operation time were compared. Results: In total, 158 patients were involved in and completed this research, including 84 cases in the group of R-EBUS with ROSE, and 74 in the group without ROSE. The diagnostic yield of ROSE group was 85.7%. Among these positive cases, 69.4% cases were malignant tumors, and 30.6% cases were benign lesions. The operation time was (24.6 ± 6.3) min. In the group without ROSE, the diagnostic yield was 70.3%, including 35 malignant tumors (67.3%), and 17 benign lesions (32.7%). The operation time was (31.5 ± 6.8) min. There were significant differences between both groups in the diagnostic yield (χ2 = 5.556, P = 0.018) and in the operation time (t = 3.187, P < 0.01). No serious procedure related complications were observed, such as pneumothorax and hemorrhage. Conclusion: ROSE can improve the diagnostic yield, and shorten the operation time. R-EBUS combined with ROSE is a safe and effective technique for peripheral pulmonary lesions.

Abstract Background: This study aimed to evaluate the diagnostic value of virtual bronchoscopic navigation combined with radial endobronchial ultrasound for peripheral pulmonary lesions (PPLs). Methods: The 105 patients with PPLs identified by computed tomography in Nanjing Brain Hospital underwent radial endobronchial ultrasound (R-EBUS) with or without virtual bronchoscopic navigation (VBN) randomly from January 2015 to December 2017. The diagnostic yield, operation time and complications were evaluated in the two groups. Results: There was no significant difference in the diagnostic yield between the VBN+R-EBUS group and the R-EBUS group (76.0% vs. 65.5%, P =0.287). The operation time in VBN+R-EBUS group was less than that in R-EBUS group (20.6±12.8 min vs. 28.6±14.3 min, P =0.016). No severe procedure related complications such as pneumothorax and hemoptysis were observed. Conclusions: VBN cannot improve the diagnostic yield, but it can shorten the operation time. The VBN combined with R-EBUS is a safe and effective technique for PPLs.

Objectives To evaluate the value of rapid on-site evaluation (ROSE) during radial probe endobronchial ultrasound transbronchial lung biopsy (rpEBUS-TBLB) for peripheral pulmonary lesions (PPLs). Methods One hundred and six patients with PPLs who received rpEBUS-TBLB were enrolled in this study. One specimen was immediately examined by ROSE and the other was sent to the central laboratory for cytologic diagnosis. The results of ROSE were compared with those of pathological diagnosis. Results The diagnostic accuracy, sensitivity, and specificity of ROSE during rpEBUS-TBLB for PPLs were 82.1%, 89.6%, and 77.1%, respectively. The procedure times and number of biopsies were less for procedures when ROSE was positive compared with those when ROSE was negative (procedure time: 20.5 ± 7.9 vs. 28.3 ± 7.6 minutes; number of biopsies: 1.6 ± 0.9 vs. 2.8 ± 0.6 times). No serious procedural complications were observed. Conclusions ROSE has value for diagnosing PPLs during rpEBUS. It can reduce procedure time, number of biopsies, and complications. ROSE combined with rpEBUS is an effective and safe method for the diagnosis of PPLs.

<b><i>Background:</i></b> The diagnostic yield of peripheral pulmonary lesions (PPLs) using radial endobronchial ultrasound (EBUS) remains challenging without navigation systems. Cone-beam computed tomography-derived augmented fluoroscopy (CBCT-AF) represents a recently developed technique, and its clinical utility remains to be investigated. <b><i>Objectives:</i></b> The aim of this study was to investigate the diagnostic yield of transbronchial biopsy (TBB) using a combination of CBCT-AF and radial EBUS. <b><i>Methods:</i></b> We recruited consecutive patients with PPLs who underwent radial EBUS-guided TBB, with or without AF, between October 2018 and July 2019. Following propensity score 1:1 matching, we recorded the procedure-related data and measured their efficacy and safety. <b><i>Results:</i></b> While 72 patients received EBUS-plus-AF, 235 patients received EBUS only. We included 53 paired patients following propensity score matching. The median size of lesions was 2.8 and 2.9 cm in the EBUS-plus-AF group and EBUS-only group, respectively. Diagnostic yield was higher in the former group (75.5 vs. 52.8%; <i>p</i> = 0.015). The diagnostic yield for the EBUS-plus-AF group was significantly higher for lesions ≤30 mm (73.5 vs. 36.1%; <i>p</i> = 0.002). Moreover, there was no significant difference in the complication rates (3.8 vs. 5.7%; <i>p</i> = 1.000). Twenty-four nodules (45.3%) were invisible by fluoroscopy in the EBUS-plus-AF group. All of them were identifiable on CBCT images and successfully annotated for AF. The mean radiation dose of total procedure, CBCT, and fluoroscopy was 19.59, 16.4, and 3.17 Gy cm<sup>2</sup>, respectively. <b><i>Conclusions:</i></b> TBB using a combination of CBCT-AF and EBUS resulted in a satisfactory diagnostic yield and safety.
