Abstract
The diagnosis of peripheral pulmonary lesions (PPLs) remains a challenge for physicians. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been applied in the diagnosis of PPLs, but its diagnostic rate varies widely. The systematic review and meta-analysis was conducted to figure out the accuracy and safety of EBUS-TBNA in the diagnosis of PPLs. We searched the PubMed and Embase databases for relevant studies published from January 1, 2000 to December 30, 2021 and used PICO (Participants, Intervention, Comparison, and Outcome) to worked out the diagnostic rate of EBUS-TBNA in PPLs. Two reviewers independently performed the data extraction and assessed study quality. Statistical analysis was carried out via R software. In 7 studies of totally 510 patients of PPLs, the overall EBUS-TBNA diagnosis yield is 0.75 (95% CI 0.67-0.84) by the random effect model. EBUS-TBNA showed a higher accuracy of 0.64 (95% CI 0.53-0.74) compared to 0.46 (95% CI 0.19-0.72) of endobronchial ultrasound-guided transbronchial biopsy (EBUS-TBB) when EBUS probe is adjacent to lesions. In the case of malignant lesions, the diagnostic rate of EBUS-TBNA is 0.79 (95% CI 0.72-0.88). Combined EBUS-TBNA with conventional bronchoscopy procedures showed the highest diagnostic yield (0.83 (95% CI 0.79-0.87)). Collectively, EBUS-TBNA should be performed firstly in patients with PPLs suspected to lung cancer especially when the EBUS probe was adjacent to the lesions. No serious procedure-related complications were observed.

Abstract
Background: The diagnosis of peripheral pulmonary nodules (PPNs) still is the key and difficult point. Previous studies have demonstrated that the diagnostic yield of radial endobronchial ultrasound (rEBUS) visible nodules is significantly higher than that of invisible nodules. The traditional method of predicting the rEBUS-visibility of nodules is based on the CT-bronchus signs, but its effectiveness may be unsatisfactory. Objective: We innovate a valuable predictive model based on virtual bronchoscopic navigation to identify beforehand which PPNs are likely to be successfully visualized by rEBUS. The innovative predictor is the ratio of the size of lesions (S) to the shortest straight-line distance (D) from the terminal point of the virtual navigation path to the localization point of the nodule. Methods: This is a retrospective study. On the training dataset of 214 patients, a receiver operating characteristic curve was drawn to understand the utility of the predictive model and get the optimal cut-off points. Ninety-two cases were enrolled in the validation dataset to validate the external predictive accuracy of the predictor. Results: The optimal cut-off point of the curve was 1.84 with the Youden index of 0.65, at which point the area under the curve was 0.85 (95% CI: 0.76-0.95). The predictor has a good performance in the validation dataset with sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 81%, 100%, 100%, 71%, and 87%, respectively. Conclusion: The S/D ratio is a valuable and innovative method to identify beforehand which PPNs are likely to be successfully visualized by rEBUS. If the S/D ratio of the nodule is greater than 1.84, it will be visualized by rEBUS.

[PMID: 35053537 PMCID: PMC8773960 DOI: 10.3390/cancers14020375] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 01/09/2022] [Accepted: 01/10/2022] [Indexed: 11/25/2022] Open
Abstract
Simple Summary Metastatic lung tumors are relatively common, and their pathological diagnosis is crucial for determining the appropriate treatment strategy. Although bronchoscopy is one biopsy method, its role has not been established for peripheral metastatic lung tumors. The present study aimed to investigate the value of bronchoscopy, using radial endobronchial ultrasound for diagnosis. We analyzed 235 lesions consecutively, and the overall diagnostic yield was 76.6%, which was slightly higher than the reported cumulative sensitivity for general peripheral pulmonary lesions. There were no serious complications. The results demonstrated that bronchoscopy is a valuable technique for peripheral metastatic lung tumors that combines diagnostic accuracy and safety. Moreover, the higher diagnostic yield was associated with the large lesion size, inner location, and visibility on radiography. These findings should contribute to the selection of biopsy methods for metastatic lung tumors and improve the diagnostic yield. Abstract Although lungs are one of the most frequent sites of metastasis for malignant tumors, little has been reported about the value of bronchoscopy for lung metastases presenting with peripheral pulmonary lesions (PPLs). This retrospective cohort study investigated the diagnostic value of bronchoscopy for peripheral metastatic lung tumors. Consecutive patients who underwent diagnostic bronchoscopy with radial endobronchial ultrasound for PPLs and were finally diagnosed with metastatic lung tumors from April 2012 to March 2019 were included. We analyzed 235 PPLs, with a median size of 18.8 mm. The overall diagnostic yield was 76.6%. In a multivariable analysis, large lesion size (>20.0 mm vs. <20.0 mm: 87.6% vs. 67.7%, p = 0.043, OR = 2.26), inner location (inner 2/3 vs. outer 1/3: 84.8% vs. 69.1%, p = 0.004, OR = 2.79), and visibility on radiography (visible vs. invisible: 83.2% vs. 56.1%, p = 0.015, OR = 3.29) significantly affected the diagnostic yield. Although a positive bronchus sign tended to have a higher yield, no significant difference was observed (81.8% vs. 70.6%, p = 0.063). Only one case of lung abscess was observed, with no serious complications. In conclusion, bronchoscopy is a valuable technique for peripheral metastatic lung tumors, with good diagnostic accuracy and safety.

Abstract
BACKGROUND An optimal sampling sequence in radial guide sheath endobronchial ultrasound lung biopsy (R-EBUS) is unclear. This prospective single-center pilot randomized controlled trial aimed to determine if the initial method and sequence of sampling affect the diagnostic accuracy of the procedure. METHODS Consecutive patients undergoing R-EBUS for lesions >15 mm with a bronchus sign were randomly assigned (1:1:1) to biopsy first (group A), brushings first (group B) or combination (group C). The primary outcome was a positive diagnosis from any sampling method. RESULTS Fifty-four patients were randomized. The overall diagnostic yield of the procedure was 77.8% (95% confidence interval: 66%-89%), with no difference between groups. A higher rate of positive cytology from brushings was seen if the biopsies were performed before brushings (77.8% in group A vs. 44.4% in group B, P=0.03). The rate of positive cytology from washings was higher if the washings were obtained just after the brushings (61.1% in group A vs. 11.1% in group B, P=0.02). There was no difference in the rate of positive biopsy histology in the groups (P=0.27). All 3 sampling modalities were more likely to be positive in group A (50.0% vs. 11.1% in group B and 22.2% in group C, P=0.04). Complications rate was low and not significantly different between groups. CONCLUSION The overall rate of a positive R-EBUS procedure was not affected by the initial sampling method or sequence. However, all 3 sampling modalities were more likely to be positive if biopsies were performed first, followed by brushings and washings.

Abstract
We report a 79-year-old woman, who had undergone surgery for papillary thyroid carcinoma 18 years previously and lung adenocarcinoma 15 years previously. She didn't receive any follow-up because she had no recurrence for 5 years in both diseases. She visited a local doctor with precordial pain and thorax discomfort as her chief complaints, where chest computed tomography indicated a 14 mm-sized nodule in the right lower lobe and 5-7 mm-sized small nodules in both lungs. Using endobronchial ultrasonography with a guide sheath (EBUS-GS) for the diagnosis in our department, the lesions were confirmed by ultrasonography, and a transbronchial biopsy was carried out under fluoroscopy. Pathologically, a sufficient amount of tumor cells were collected, and the findings of adenocarcinoma were obtained. Her condition was diagnosed as recurrent pulmonary metastases of thyroid papillary carcinoma because of the atypical columnar epithelial cells with nuclear variants and the papillary proliferation of intranuclear inclusion, and because of the positive findings in immunohistochemical staining for thyroglobulin. Since papillary thyroid carcinoma is positive for thyroid transcription factor-1 (TTF-1), which is widely used as a marker of lung adenocarcinoma, it cannot be used to differentiate between the two. It is often difficult to diagnose papillary thyroid carcinoma by bronchoscopy, because its progress is slow and the origin of the metastatic lung tumor is not in the bronchus, unlike primary lung cancer. However, a devised transbronchial biopsy procedure for slowly progressive metastatic lung tumors such as papillary thyroid carcinoma is considered to be a useful technique for diagnosis.

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.

Abstract
Bronchoscopy has a lower diagnostic yield for peripheral lung lesions (PLL). Endobronchial ultrasound guide sheath transbronchial lung biopsy (EBUS GS TBLB) has been used to overcome such limitation. Recent studies revealed that combined methods (e.g., EBUS GS TBLB plus electromagnetic navigation [EMN] or virtual bronchoscopic navigation [VBN]) further improve the diagnostic yield. However, those systems are associated with a high cost burden. Accordingly, we attempted to use VBN by computed tomography (CT) workstation (Aquarius iNtuition, TeraRecon) not dedicated only for VBN as an adjunctive tool for EBUS GS TBLB. We performed a prospective registry study to investigate whether VBN by CT workstation could improve the diagnostic yield of PLL.Between February 2017 and February 2018, 128 patients with PLL were divided into 2 groups (VBN and non-VBN [NVBN]). In NVBN group (n = 64), EBUS GS TBLB was performed using a hand-drawn bronchial map based on CT images. VBN group (n = 64) underwent EBUS GS TBLB using VBN images.VBN using CT workstation did not improve the diagnostic yield of EBUS GS TBLB for PLL (VBN vs NVBN, 72% vs 80%, P = .284). VBN slightly reduced procedure time (minute [mean ± SD], 25.31 ± 10.33 vs 25.81 ± 9.22), navigation time (time to find the lesion) (9.10 ± 7.88 vs 9.50 ± 7.14), and fluoroscopy time (2.23 ± 2.39 vs 2.86 ± 4.61), while these differences were not statistically significant.The diagnostic yield of EBUS GS TBLB was not improved with VBN (compared with using a hand-drawn bronchial map). Although VBN slightly shortened the procedure-related times, which were not significantly different.

Abstract
Bronchoscopic sampling of PPL was significantly advanced by the development of the endobronchial ultrasound guide sheath method in the 1990s. Since then, a range of technical and procedural techniques have further advanced diagnostic yields. These include the use of thinner bronchoscopes with better working channel diameters, understanding the importance of peripheral transbronchial needle aspiration, and virtual bronchoscopic assistance. These have enabled better sampling of smaller and more technically challenging lesions including ground-glass nodules. Most recently, robotic bronchoscopy has been developed which, among other refinements, allows fine control of visual bronchoscopic navigation by replacing movements directed by the hand with electronic consoles and trackballs, and innovatively integrate virtual with real bronchoscopic pathways. The requirement for PPL diagnosis and treatment is expected to increase with more chest CT performed as part of CT screening programmes.

Abstract
BACKGROUND Bronchoscopy is important to diagnose lung cancer. However, some patients who undergo bronchoscopic procedures develop respiratory tract infections. Little is known about the proportion of pathogen-positive results in bacterial cultures from diagnostic bronchoscopy samples in patients with suspected lung cancer. This study aimed to determine the rate of positive bacterial cultures after diagnostic bronchoscopy in patients with suspected lung cancer and the relationship among culture results, clinical characteristics, and respiratory tract infections. METHODS We retrospectively reviewed the medical records of all immunocompetent patients who underwent bronchoscopy and had culture and histological samples for the diagnosis of peripheral pulmonary lesions from September 2012 to August 2014 at the National Cancer Center in Tokyo. We analyzed data and classified radiological lesions into the following categories: calcifications, cavitations, low-density areas, margin irregularities, and satellite nodules. RESULTS The study population consisted of 328 patients (median age, 69 years). We found that 65.9% of patients had malignant lesions and 4.2% of patients had positive cultures for pathogenic bacteria. The number of calcifications (p = 0.002, 95% CI: 2.17-41.10) was significantly higher in patients with positive bacterial isolates, according to the multivariate analysis, and bacterial culture positivity was not associated with the development of respiratory complications after bronchoscopy. Of the three patients with respiratory complications, all presented with cavitations. CONCLUSION Because of the low prevalence of positive bacterial cultures in patients with suspected lung cancer, bacterial culture may be limited to specific patients, such as those with calcifications. Lesions with cavitation warrant close monitoring.

Abstract
肺癌是全球癌症相关死亡的主要原因, 肺癌的治愈率很低, 不仅因其自身攻击性, 还因对肺癌筛查的忽视。随着肺部筛查手段的不断进展, 肺外周病变的检出率逐渐提高, 当前对外周肺病变进行诊断的最常用方法是经支气管行支气管镜检查或计算机断层扫描(computed tomography, CT)引导下经皮穿刺针吸/活检, 然而对于外周肺病灶, 支气管镜检查有较低的诊断率, 经皮穿刺检查有较高的气胸发生率, 因此, 使用安全、微创的方法对外周肺病变进行组织确诊是临床工作者将面临的挑战。新型支气管镜介入诊断技术已逐渐用于临床, 这些技术可有效提高外周肺病变的诊断率, 缩短诊断时间, 使患者获得及时有效的治疗。本文将现有的技术进行简要综述以帮助临床医生尝试应用这些微创技术。

Abstract
The diagnosis of pulmonary nodules can be made using several methods including computed tomography (CT)-guided fine-needle aspiration (FNA), radial endobronchial ultrasound (EBUS)-guided sampling techniques (transbronchial lung biopsy [TBLB], transbronchial brush, bronchoalveolar lavage, or transbronchial needle aspiration [TBNA]), or occasionally with convex probe (CP) EBUS-TBNA. While CT-guided FNA is associated with a high (25%) rate of pneumothorax, the CP-EBUS cannot reach lesions beyond the interlobar region. Radial EBUS-guided TBLB and transbronchial brushing are excellent modalities in the evaluation of peripheral pulmonary lesions. However, these techniques cannot access lesions that are located adjacent to the proximal segmental bronchus, due to the presence of a cartilaginous wall. Herein, we describe a 58-year-old man, who presented with a lung nodule in the right middle lobe, wherein radial EBUS-guided TBNA proved to be the most appropriate diagnostic modality. We also discuss the current utility of radial EBUS-guided TBNA in day-to-day practice.

Abstract
Endobronchial ultrasonography using a guide sheath (EBUS-GS) is a novel method used for collecting peripheral pulmonary lesion (PPL) samples. EBUS-GS is performed by introducing a guide sheath-covered miniprobe into the target bronchus and then withdrawing the miniprobe after lesion detection, leaving the guide sheath in situ as a working channel for obtaining lesion samples. EBUS-GS can improve PPL diagnosis rates and be used for obtaining specimens for molecular analysis. In this review, we discuss the clinical applications of EBUS-GS, the factors that affect its diagnostic sensitivity, and potential complications. We also compare EBUS-GS with other available diagnostic techniques and discuss the strengths and limitations of this method.

Abstract
INTRODUCTION: Since the National Lung Screening Trial demonstrated the utility of low-dose computed tomography screening for lung cancer, the detection rate of ground-glass nodules (GGNs) has increased. Endobronchial ultrasound with a guide sheath (EBUS-GS) is widely performed to diagnose peripheral pulmonary lesions, but there are not enough reports on the predictive ability of EBUS-GS in diagnosing GGNs. The aim of this study is to investigate the predictive factors for a successful diagnostic bronchoscopy for GGNs. METHODS: Consecutive patients who underwent diagnostic bronchoscopy for GGNs from September 2012 to January 2016 were enrolled in this study. From these, cases who underwent EBUS-GS were selected. They were reviewed and analyzed to examine the association between the diagnostic yield and the following clinical factors: lesion size, lobar position, location, consolidation-to-tumor ratio, visibility on X-ray, use of virtual bronchoscopy, bronchus sign, guide sheath size, and number of biopsies. RESULTS: We enrolled 254 cases, of which 167 were diagnosed using EBUS-GS (65.7% diagnostic yield). Univariate analysis indicated that a positive bronchus sign was a significant factor for higher diagnostic yield (72.9% vs. 34.0%; P < 0.001). The use of virtual bronchoscopy also tended toward a higher yield, but the result was not significant (69.0% vs. 54.4%; P = 0.058). However, multivariate analysis indicated that both were significantly associated with higher diagnostic yield (P < 0.001, odds ratio [OR]: 5.35; P < 0.001, OR: 1.97, respectively). CONCLUSIONS: Our results suggest that a positive bronchus sign and the use of virtual bronchoscopy are positive predictive factors for successful diagnostic bronchoscopy of GGNs.

Abstract
The diagnosis and staging of patients with lung cancer has relied on tissue sampling. Endobronchial ultrasound (EBUS) is a minimally invasive procedure for the rapid and safe acquisition of tissue and can be done easily and repeatedly. EBUS transbronchial needle aspiration (TBNA) is now the standard for diagnosis of mediastinal and hilar lymphadenopathy and should be considered in patients who have a high probability of lymph node metastases without systemic involvement. EBUS also provides guidance for biopsy of peripheral lung lesions. Recent advances of EBUS with new techniques help to improve the diagnostic yield and decrease the complication rate and total procedure time.

Radial endobronchial ultrasound with a guide sheath for diagnosis of peripheral cavitary lung lesions: a retrospective study. BMC Pulm Med 2016; 16:76. [PMID: 27170169 PMCID: PMC4866378 DOI: 10.1186/s12890-016-0244-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2016] [Accepted: 05/05/2016] [Indexed: 11/10/2022] Open
Abstract
Background Radial endobronchial ultrasound with a guide sheath (EBUS-GS) has improved the diagnostic outcomes of peripheral lung lesions. However, to our knowledge, reports on the use of EBUS-GS for diagnosis of cavitary lesions are unavailable. Therefore, this study aimed to assess the effectiveness and safety of EBUS-GS for diagnosis of peripheral cavitary lung lesions (PCLLs). Methods This study was a single-institution retrospective review of PCLLs examined by using EBUS-GS between July 2013 and October 2015. The diagnostic results of different EBUS-GS samples, including cytologic, histopathologic, and microbiologic samples, were analysed separately. Results Of 696 radial EBUS procedures performed during the study period, 50 were performed for examination of PCLLs. The overall diagnostic yield for EBUS-GS was 80 % (40/50). Regarding 27 malignant lesions, the diagnostic yields for cytologic and histopathologic samples were 63.0 % (17/27) and 74.1 % (20/27), respectively. Regarding 23 benign lesions, the diagnostic yields for histopathologic and microbiologic samples were 69.6 % (16/23) and 47.8 % (11/23), respectively. Uni- and multivariate analyses indicated that the EBUS probe being within the lesion was the only factor significantly associated with increased diagnostic yield (odds ratio, 7.04; P = 0.03). Although pulmonary infection occurred after the procedure in 1 patient (2.0 %), no other complications, including pneumothorax or significant haemorrhage, were reported. Conclusion EBUS-GS was found to be an effective and safe procedure for diagnosis of PCLLs.
