Established Technique

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.

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.

<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.
