Lin CK, Wu SH, Chua YW, Fan HJ, Cheng YC. TransEBUS: The interpretation of endobronchial ultrasound image using hybrid transformer for differentiating malignant and benign mediastinal lesions. J Formos Med Assoc 2024:S0929-6646(24)00216-X. [PMID: 38702216 DOI: 10.1016/j.jfma.2024.04.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 03/14/2024] [Accepted: 04/24/2024] [Indexed: 05/06/2024] Open
Abstract
The purpose of this study is to establish a deep learning automatic assistance diagnosis system for benign and malignant classification of mediastinal lesions in endobronchial ultrasound (EBUS) images. EBUS images are in the form of video and contain multiple imaging modes. Different imaging modes and different frames can reflect the different characteristics of lesions. Compared with previous studies, the proposed model can efficiently extract and integrate the spatiotemporal relationships between different modes and does not require manual selection of representative frames. In recent years, Vision Transformer has received much attention in the field of computer vision. Combined with convolutional neural networks, hybrid transformers can also perform well on small datasets. This study designed a novel deep learning architecture based on hybrid transformer called TransEBUS. By adding learnable parameters in the temporal dimension, TransEBUS was able to extract spatiotemporal features from insufficient data. In addition, we designed a two-stream module to integrate information from three different imaging modes of EBUS. Furthermore, we applied contrastive learning when training TransEBUS, enabling it to learn discriminative representation of benign and malignant mediastinal lesions. The results show that TransEBUS achieved a diagnostic accuracy of 82% and an area under the curve of 0.8812 in the test dataset, outperforming other methods. It also shows that several models can improve performance by incorporating two-stream module. Our proposed system has shown its potential to help physicians distinguishing benign and malignant mediastinal lesions, thereby ensuring the accuracy of EBUS examination.

Abstract
PURPOSE It is unclear whether performing endosonography first in non-small cell lung cancer (NSCLC) patients with radiological N1 (rN1) has any advantages over surgery without nodal staging. We aimed to compare surgery without endosonography to performing endosonography first in rN1 on the overall survival (OS) of patients with NSCLC. MATERIALS AND METHODS This is a retrospective analysis of patients with rN1 NSCLC between 2013 and 2019. Patients were divided into 'no endosonography' and 'endosonography first' groups. We investigated the effect of nodal staging through endosonography on OS using propensity score matching (PSM) and multivariable Cox proportional hazard regression analysis. RESULTS In the no endosonography group, pathologic N2 occurred in 23.0% of patients. In the endosonography first group, endosonographic N2 and N3 occurred in 8.6% and 1.6% of patients, respectively. Additionally, 51 patients were pathologic N2 among 249 patients who underwent surgery and mediastinal lymph node dissection (MLND) in endosonography first group. After PSM, the 5-year OSs were 68.1% and 70.6% in the no endosonography and endosonography first groups, respectively. However, the 5-year OS was 80.2% in the subgroup who underwent surgery and MLND of the endosonography first group. Moreover, in patients receiving surgical resection with MLND, the endosonography first group tended to have a better OS than the no endosonography group in adjusted analysis using various models. CONCLUSION In rN1 NSCLC, preoperative endosonography shows better OS than surgery without endosonography. For patients with rN1 NSCLC who are candidates for surgery, preoperative endosonography may help improve survival through patient selection.

Abstract
Objective Endobronchial ultrasound-guided transbronchial needle injection (EBUS-TBNI) may effectively treat acute pulmonary embolisms (PEs). Here, we assessed the effectiveness of clot dissolution and safety of tissue plasminogen activator (t-PA) injection using EBUS-TBNI in a 1-week survival study of a porcine PE model. Methods Six pigs with bilateral PEs were used: 3 for t-PA injection using EBUS-TBNI (TBNI group) and 3 for systemic administration of t-PA (systemic group). Once bilateral PEs were created, each 25 mg of t-PA injection using EBUS-TBNI for bilateral PEs (a total of 50 mg t-PA) and 100 mg of t-PA systemic administration was performed on day 1. Hemodynamic parameters, blood tests, and contrast-enhanced computed tomography scans were carried out at several time points. On day 7, pigs were humanely killed to evaluate the residual clot volume in the pulmonary arteries. Results The average of percent change of residual clot volumes was significantly lower in the TBNI group than in the systemic group (%: systemic group 36.6 ± 22.6 vs TBNI group 9.6 ± 6.1, P < .01) on day 3. Considering the elapsed time, the average decrease of clot volume per hour at pre-t-PA to post t-PA was significantly greater in the TBNI group than in the systemic group (mm3/hour: systemic 68.1 ± 68.1 vs TBNI 256.8 ± 148.1, P < .05). No hemorrhage was observed intracranially, intrathoracically, or intraperitoneally on any contrast-enhanced computed tomography images. Conclusions This study revealed that t-PA injection using EBUS-TBNI is an effective and safe way to dissolve clots.

BMC Anesthesiol 2023; 23:276. [PMID: 37587423 PMCID: PMC10428560 DOI: 10.1186/s12871-023-02241-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 08/11/2023] [Indexed: 08/18/2023] Open
Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can be performed in a wide range, from minimal sedation to general anesthesia. Advanced age increases perioperative risks related to anesthesia and is also associated with many pathological processes that further increase morbidity and mortality. The ideal sedation protocol for EBUS-TBNA has yet to be determined in geriatric patients. Deep sedation (DS) may increase the safety and performance of the procedure. There are limited studies evaluating the effectiveness and safety of EBUS-TBNA under DS in elderly patients. METHODS 280 patients who underwent EBUS-TBNA under DS were included in this retrospective study. 156 patients aged 65 years and over (Group 1) and 124 patients under 45 (Group 2) were compared. Demographic data, comorbidities, pulmonary function tests (PFTs), hemodynamic measurements, and peripheral oxygen saturation (SpO2) before the procedure were evaluated. In addition, the duration of the EBUS-TBNA procedure, sedation agents and dosages, recovery time, and complications related to the procedure in the 24 h and applied medications and treatments were recorded. RESULTS There was no difference in body mass index, EBUS-TBNA procedure duration, and recovery time between geriatric and young patients(p > 0.05). The proportion of female patients, pre-anesthesia SpO2, and PFTs were found to be significantly lower in geriatric patients(p < 0.05). ASA classification, frequency of comorbidities, and initial mean arterial pressure were found to be significantly higher in the geriatric group(p < 0.05). The propofol-ketamine combination was the most preferred sedative in both groups. The dose of propofol used in the regimen in which propofol was administered alone was found to be lower in the elderly group (p < 0.05). The increase in the HR was significant in Group 2 in the T4 and T5 periods with respect to T1 when the differences were compared (p < 0.05). As a complication, the frequency of high blood pressure during the procedure was higher in the elderly group (p < 0.05). CONCLUSIONS The EBUS-TBNA procedure performed under DS was safe in elderly and young patients. Our study showed that the procedure and recovery times were similar in the elderly and young groups. The incidence of temporary high blood pressure during the procedure was higher in the elderly patients. The other complication rates during the procedure were similar in groups. Decreased propofol dose in the regimen using propofol alone has shown us that anesthetists are more sensitive to the administration of sedative agents in geriatric patients, taking into account comorbidities and drug interactions.

Abstract
Endobronchial Ultrasound (EBUS) has been widely used to stage lung tumors and to diagnose mediastinal diseases. In the last decade, this procedure has evolved in several technical aspects, with new tools available to optimize tissue sampling and to increase its diagnostic yield, like elastography, different types of needles and, most recently, miniforceps and cryobiopsy. Accordingly, the indications for the use of the EBUS scope into the airways to perform the Endobronchial Ultrasound-TransBronchial Needle Aspiration (EBUS-TBNA) has also extended beyond the endobronchial and thoracic boundaries to sample lesions from the liver, left adrenal gland and retroperitoneal lymph nodes via the gastroesophageal tract, performing the Endoscopic UltraSound with Bronchoscope-guided Fine Needle Aspiration (EUS-B-FNA). In this review, we summarize and critically discuss the main indication for the use of the EBUS scope, even the more uncommon, to underline its utility and versatility in clinical practice.

Abstract
BACKGROUND Since their introduction, both linear and radial endobronchial ultrasound (EBUS) have become an integral component of the practice of Pulmonology and Thoracic Oncology. The quality of health care can be measured by comparing the performance of an individual or a health service with an ideal threshold or benchmark. The taskforce sought to evaluate quality indicators in EBUS bronchoscopy based on clinical relevance/importance and on the basis that observed significant variation in outcomes indicates potential for improvement in health care outcomes. METHODS A comprehensive literature review informed the composition of a comprehensive list of candidate quality indicators in EBUS. A multiple-round modified Delphi consensus process was subsequently performed with the aim of reaching consensus over a final list of quality indicators and performance targets for these indicators. Standard reporting items were developed, with a strong preference for items where evidence demonstrates a relationship with quality indicator outcomes. RESULTS Twelve quality Indicators are proposed, with performance targets supported by evidence from the literature. Standardized reporting items for both radial and linear EBUS are recommended, with evidence supporting their utility in assessing procedural outcomes presented. CONCLUSION This statement is intended to provide a framework for individual proceduralists to assess the quality of EBUS they provide their patients through the identification of clinically relevant, feasible quality measures. Emphasis is placed on outcome measures, with a preference for consistent terminology to allow communication and benchmarking between centres.

Abstract
Lung cancer is the most lethal cancer type in Taiwan and worldwide. Early detection and treatment advancements have improved survival. However, small peripheral pulmonary nodules (PPN) biopsy is often challenging, relying solely on bronchoscopy with radial endobronchial ultrasound (EBUS). Augmented fluoroscopy overlays the intra-procedural cone-beam computed tomography (CBCT) images with fluoroscopy enabling real-time three-dimensional localization during bronchoscopic transbronchial biopsy. The hybrid operating room (HOR), equipped with various types of C-arm CBCT, is a perfect suite for PPN diagnosis and other interventional pulmonology. This study shares the single institute experience of EBUS transbronchial biopsy of PPN with the aid of augmented fluoroscopic bronchoscopy (AFB) and CBCT in an HOR. We retrospectively enrolled patients who underwent robotic CBCT, augmented fluoroscopy-guided, radial endobronchial ultrasound-confirmed transbronchial biopsy and cryobiopsy in a hybrid operating room. Patient demographic characteristics, computed tomography images, rapid on-site evaluation cytology, and final pathology reports were collected. Forty-one patients underwent transbronchial biopsy and 6 received additional percutaneous transthoracic core-needle biopsy during the same procedure. The overall diagnostic yield was 88%. The complications included three patients with pneumothorax after receiving subsequent CT-guided percutaneous transthoracic needle biopsy, and two patients with hemothorax who underwent transbronchial cryobiopsy. Overall, the bronchoscopic biopsy of PPN using AFB and CBCT as precise guidance in the hybrid operating room is feasible and can be performed safely with a high diagnostic yield.

Abstract
PURPOSE OF REVIEW In the history of bronchoscopy, the advent of flexible transbronchial needle aspiration (TBNA) before and, subsequently, of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), have represented fundamental events, as they have significantly and definitively changed interventional pulmonology's role in diagnostic and therapeutic work-up of most of thoracic diseases.Purpose of this historical review is to retrace the main stages that have contributed to the development of these two techniques. RECENT FINDINGS TBNA allowed the bronchoscopists to overcome the barrier of the tracheobronchial wall and to obtain samples from hilar-mediastinal lesions. With this additional method, bronchoscopy has become an essential procedure for staging of lung cancer.The advent of echo-bronchoscopes, allowing to perform TBNA under direct ultrasound guidance in real time, further increased the diagnostic yield of this technique. Furthermore, the insertion of the echo-bronchoscope through the oesophagus allowed to extend the landscape of targets to sample, including also para-esophageal lesions, liver metastases, celiac nodes and left adrenal glands.EBUS-TBNA has shown its usefulness not only in the approach to mediastinal lesions, but also in other clinical conditions, such as lung nodules or masses adjacent to the tracheobronchial tree. SUMMARY Despite the obvious advantages of EBUS-TBNA, this technology is not yet available in many centres and countries worldwide. For this reason, TBNA remains a basic technique that must complete the technical background of bronchoscopists and it should not be forgotten.

[PMID: 36525475 PMCID: PMC9891861 DOI: 10.1111/1759-7714.14719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 10/21/2022] [Accepted: 10/22/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Few studies assessed the use of endobronchial ultrasound (EBUS)-guided re-biopsy for detecting the T790M mutation after epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) failure. METHODS A total of 2996 EBUS procedures were performed during the study period (January 2019-June 2022). In total, 44 consecutive patients who underwent EBUS-guided re-biopsy (56 procedures) for detecting the T790M mutation were analyzed. The success rates and T790M mutation frequencies were analyzed according to the re-biopsy site and EBUS method. Multivariate logistic regression analyses were used to identify factors affecting the likelihood of the T790M mutation. RESULTS The success rates for the mutation analyses using EBUS with a guide-sheath (EBUS-GS), EBUS guided transbronchial needle aspiration (EBUS-TBNA), and EBUS-GS with EBUS-TBNA for re-biopsy were 80.6% (29/36), 93.3% (14/15), and 100% (5/5), respectively. Patients who underwent lymph node biopsy using EBUS-TBNA had an increased rates of the T790M mutation compared with those undergoing lung biopsy using EBUS-GS (EBUS-TBNA, 60.0%; EBUS-GS with EBUS-TBNA, 40.0%; EBUS-GS, 11.1%; p < 0.001). In multivariate analysis, the use of a first-generation EGFR-TKI (odds ratio [OR], 4.29; 95% confidence interval [CI], 1.05-17.58; p = 0.043) was associated with occurrence of the T790M mutation. Re-biopsy of the metastatic site tended to be associated with a higher T790M mutation rate. Mild hemoptysis occurred in 3.6% (2/56) of the patients. CONCLUSIONS EBUS-guided re-biopsy can be used for detecting the T790M mutation in patients who failed EGFR-TKI therapy. The T790M mutation frequency differed according to the re-biopsy site. The use of a first-generation EGFR-TKI was an independent predictor of the T790M mutation.

Abstract
OBJECTIVE We compared dexmedetomidine-remifentanil vs. propofol-remifentanil in terms of safety and quality during sedation for Endobronchial ultrasonography (EBUS). METHODS A randomized, double-blind trial. Outpatients undergoing EBUS randomly received 1 μg/kg/hour dexmedetomidine or a target concentration of 2.5 μg/mL propofol, both combined with remifentanil initially targeted at 1.5 ng/mL and subsequently titrated. Additional sedatives were restricted. The primary outcome was the need for airway rescue interventions to treat oxygen desaturation. RESULTS Twenty-eight patients received dexmedetomidine-remifentanil and 27 received propofol-remifentanil. Airway rescue interventions were fewer in the dexmedetomidine group vs. the propofol one (23 vs. 76% patients, relative risk 3.21 (95% CI 1.55-6.64, P < 0.002)). Desaturation in the dexmedetomidine group was always resolved by increasing nasal oxygen flow, whereas additional interventions were needed in 60% of patients receiving propofol. Hypotension was more frequent in the propofol group, while hypertension, bradycardia and coughing were similar in both. Bronchoscopists' and patients' satisfaction were similar, although in the dexmedetomidine group two patients needed additional sedatives and two patients would not repeat the sedation technique. CONCLUSION Moderate sedation with dexmedetomidine-remifentanil for EBUS is safer than deep sedation with propofol-remifentanil but it would occasionally need additional sedatives to ensure patient satisfaction.

Abstract
Background Concurrent bronchoscopy using radial probe and convex endobronchial ultrasound (RP‐ and CP‐EBUS) is used to simultaneously evaluate both peripheral lung lesions for the histological diagnosis of the primary tumor and mediastinal lymph nodes for mediastinal staging. So far, little is known about the combined procedure with RP‐ and CP‐EBUS. Methods Between January 2020 and March 2021, the bronchoscopy database was reviewed to identify the clinical outcomes of the combined procedure with RP‐ and CP‐EBUS. Patients who underwent transbronchial biopsy using RP‐EBUS alone were classified as the RP‐EBUS group, while those who underwent a combined procedure with RP‐ and CP‐EBUS were classified as the combination group. Results The overall diagnostic yield of the bronchoscopic procedure in the combination group was significantly higher than the RP‐EBUS group (90.7% vs. 70.0%, p < 0.001). CP‐EBUS increased the diagnostic yield of the bronchoscopic procedure in the combination group by 9.3%. Although the mean procedure time was significantly longer, and the mean doses of midazolam and fentanyl were significantly higher in the combination group (p < 0.001), there were no differences in the overall complication rates between the two study groups (1.4% and 1.0% for the RP‐EBUS and combination groups, respectively, p = 0.766). Conclusions Combined bronchoscopy using RP‐ and CP‐EBUS is feasible and safe. In addition to mediastinal staging, CP‐EBUS increased the overall diagnostic yield of the bronchoscopic procedure by 9.3%.

Clinical utility of EBUS-TBNA of hilar, interlobar, and lobar lymph nodes in patients with primary lung cancer. Thorac Cancer 2022; 13:2507-2514. [PMID: 35859356 PMCID: PMC9436691 DOI: 10.1111/1759-7714.14587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Revised: 07/05/2022] [Accepted: 07/08/2022] [Indexed: 11/27/2022] Open
Abstract
Background Endobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA) is used to evaluate hilar/interlobar/lobar lymph nodes. This study aimed to assess the clinical utility of EBUS‐TBNA for station 10/11/12 lymph nodes (LNs) in patients with primary lung cancer. Methods This was a retrospective analysis of a prospectively collected database of patients with primary lung cancer who underwent EBUS‐TBNA for station 10/11/12 LNs from January 2015 to December 2019. Patients with benign results from EBUS‐TBNA who did not undergo surgical sampling/clinical follow‐up or who received radiotherapy/chemotherapy were excluded. Results The analyses were conducted on 889 LNs from 797 patients. The overall diagnostic sensitivity, specificity, accuracy, negative predictive value (NPV), and positive predictive value of EBUS‐TBNA were 95.7, 100, 97.3, 93.2, and 100%, respectively. Diagnostic sensitivity was significantly lower for LNs <10 mm than ≥10 mm in size (90.1% vs. 97.8%; p < 0.001). There was no significant difference in diagnostic performance according to the nodal station (10 vs. 11/12) and left‐ versus right‐sided LNs. The diagnostic sensitivity (100 vs. 95.5%; p = 0.221) and specificity (100 vs. 100%) of N3 LNs was not significantly different from those of N1 LNs. In this study, eight (8/91, 8.8%) patients with cN1 NSCLC received neoadjuvant treatment based on the results of EBUS‐TBNA. Conclusion EBUS‐TBNA accurately evaluates station 10/11/12 LNs of both N1 and N3 disease. The diagnostic performances of EBUS‐TBNA for station 10/11/12 LNs seem to be comparable to those of EBUS‐TBNA for mediastinal LNs.

Abstract
Background This study discusses the developmental trends and research hotspots in bronchoscopy anesthesia in the past six decades. Methods The original and review articles published from 1975 to June 2021 related to bronchoscopy anesthesia were retrieved from the Web of Science Core Collection (WoSCC). Three different scientometric tools (CiteSpace, VOSviewer, and Bibliometrix) were used for this comprehensive analysis. Results There was a substantial increase in the research on bronchoscopy anesthesia in recent years. A total of 1,270 publications were retrieved up to June 25, 2021. Original research articles were 1,152, and reviews were 118, including 182 randomized controlled trials (RCTs). These publications were cited a total of 25,504 times, with a mean of 20.08 citations per publication. The US had the largest number of publications (27.6%) and the highest H-index of 44. The sum of publications from China ranked second (11.5%), with an H-index of 17. Keyword co-occurrence and references co-citation visual analysis showed that the use of sedatives such as dexmedetomidine in the process of bronchoscopy diagnosis and treatment was gradually increasing, indicating that bronchoscopy anesthesia was further progressing toward safety and comfort. Conclusion Based on a bibliometric analysis of the publications over the past decades, a comprehensive analysis indicated that the research of bronchoscopy anesthesia is in a period of rapid development and demonstrated the improvement of medical instruments and surgical options that have significantly contributed to the field of bronchoscopy anesthesia. The data would provide future directions for clinicians and researchers in relation to bronchoscopy anesthesia.

Abstract
High-frequency endoscopic ultrasound (HFEUS) imaging is an important tool commonly used in clinical practice for imaging hollow organs. The virtual source synthetic aperture (VSSA) method is effective in improving the imaging quality of HFEUS. However, interference from the motor control unit severely affects the accuracy of the conventional delay and sum (DAS) method, thus compromising the effectiveness of VSSA. In this article, a new computational method based on phase correction was proposed to overcome these shortcomings, which is named phase-corrected-and-sum (PCAS). Meanwhile, the parameters of coherence factor weighting (CFW) can be obtained from the correlation coefficient of the superimposed signals to further increase the imaging quality. Three kinds of imaging experiments were designed to evaluate the proposed method. Compared with the conventional method, the results show that the PCAS-CFW method improves the lateral resolution by about 10% and the contrast-to-noise ratio (CNR) by about 44%. Therefore, this proposed method is capable of significantly improving HFEUS image quality, and this method can be easily integrated into current HFEUS imaging systems, showing great potential for clinical applications.

Abstract
BACKGROUND The safety and efficacy of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in patients aged 70 years and older has been established. However, few studies have evaluated the safety, usefulness, and significance of EBUS-TBNA in patients aged 80 years and older. METHODS We retrospectively investigated patients aged 80 years and older who underwent EBUS-TBNA under local anesthesia. The study period was 10 years; from November 1, 2010 to October 31, 2020. The primary endpoint was the safety of EBUS-TBNA, which was measured as the incidence of complications associated with the procedure. The secondary endpoints were the overall diagnostic rate, malignant disease diagnosis rate, and malignant disease treatment rate. RESULTS A total of 111 patients were enrolled in the study, and the median age was 82 years (range: 80-89 years). The incidence of complications (the primary endpoint) was 5% (5/111) and comprised oversedation in one case, chest pain in one case, hypoxemia in two cases, and arrhythmia in one case. Regarding the secondary endpoints, the diagnostic rate for all patients was 75% (83/111), and the diagnostic rate of malignant disease was 89% (75/84). Of the 75 patients with malignant disease diagnosed with EBUS-TBNA, 61 (81%) received tumor-specific therapy in accordance with their diagnoses. CONCLUSION EBUS-TBNA can be considered safe and effective even in patients aged 80 years and older.

Eknewir S, John TJ, Bennji SM, Koegelenberg CFN. The utility of endobronchial ultrasound-guided transbronchial needle aspiration in a community with a high HIV and tuberculosis burden. Afr J Thorac Crit Care Med 2022; 28:10.7196/AJTCCM.2022.v28i1.156. [PMID: 35814170 PMCID: PMC9255698 DOI: 10.7196/ajtccm.2022.v28i1.156] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/07/2022] [Indexed: 11/18/2022] Open
Abstract
Background Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become the gold standard in diagnosing and performing nodal staging in patients with suspected lung cancer and diagnosing other malignant and benign diseases. Studies from countries with low tuberculosis (TB) incidence suggest that it has a sensitivity of 90 - 95% and a specificity of 100%. Objectives To investigate the utility of EBUS-TBNA in a community with a high HIV and TB burden. Methods We retrospectively reviewed all patients who underwent EBUS-TBNA to confirm a tissue diagnosis during a 2-year period from January 2017 - December 2018. Only patients with complete medical, pathology and radiology records and follow-up were included. Results During the 2 years, a total of 201 patients underwent EBUS-TBNA. Some patients (n=19) had incomplete notes or follow-up and 104 cases were ultimately diagnosed with benign nodal disease. In the 182 patients who were ultimately included in the present study, EBUS-TBNA had a sensitivity of 95.1% (95% confidence interval (CI) 88.6 - 98.2), specificity of 100% (95% CI 94.20 - 100), positive predictive value (PPV) of 100.00% (95% CI 95.3 - 100) and negative predictive value (NPV) of 94.1% (95% CI 86.0 - 97.8) for all diagnoses. The overall diagnostic accuracy was 97.3% (95% CI 93.9 - 99.2). Out of the 64 patients who had lung cancer, EBUS-TBNA had a sensitivity of 95.2% (95% CI 86.7 - 99.0), specificity of 100% (95% CI 5.5 - 100), PPV of 100.0% and NPV of 58.3% (95% CI 31.7 - 80.9). The overall diagnostic accuracy for lung cancer was 95.5% (95% CI 87.2 - 99.1%). Conclusion EBUS-TBNA has high diagnostic accuracy, even in a population with a high HIV and TB burden.

Endobronchial Ultrasound Transbronchial Needle Aspiration With a 19-Gauge Needle vs 21- and 22-Gauge Needles for Mediastinal Lymphadenopathy. Chest 2022; 162:712-720. [PMID: 35381259 DOI: 10.1016/j.chest.2022.03.041] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 02/18/2022] [Accepted: 03/21/2022] [Indexed: 10/18/2022] Open
Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used to evaluate mediastinal lymphadenopathy. Studies focusing on malignant lymphadenopathy have compared 21- and 22-gauge (21G and 22G, respectively) needles and have not identified an advantage of one needle size over the other in terms of diagnostic yield. RESEARCH QUESTION Does the 19-gauge (19G) EBUS needle offer greater diagnostic yield and sensitivity vs the 21G and 22G EBUS needles for a diagnosis of sarcoidosis, lymphoma, or mediastinal lymphadenopathy not yet diagnosed? STUDY DESIGN AND METHODS This study retrospectively examined records of 730 patients from the Stather Canadian Outcomes Registry for Chest Procedures (SCOPE) database who underwent EBUS-TBNA for a diagnosis of suspected sarcoidosis, lymphoma, or mediastinal lymphadenopathy not yet diagnosed. A propensity score analysis of two groups was performed. One group comprised patients undergoing EBUS-TBNA with a 19G needle, the other with a 21G or 22G needle. Cases for analysis were selected with a 1:2 ratio of 19G vs 21/22G using logistic regression and random matching with all eligible 19G cases included. RESULTS There were 137 patients (312 targets) in the 19G group and 274 patients (631 targets) in the 21/22G group in the propensity score analysis. The diagnostic yield was 107 of 137 (78.1%) in the 19G group vs 194 of 274 (70.8%) in the 21/22G group (difference, 7.3%; 95% CI, -1.9 to 15.6; P = .116). The sensitivity of EBUS-TBNA for sarcoidosis was 80 of 84 (95.2%) in the 19G group vs 150 of 156 (96.2%) in the 21/22G group (difference, 1.0%; 95% CI, -4.2 to 8.2; P = .71). In patients with a final diagnosis of lymphoma, EBUS was diagnostic in 10 of 13 (76.9%) in the 19G group vs 12 of 12 (100%) in the 21/22G group (difference, 23.1%; 95% CI, -5.4 to 50.3; P = .08). INTERPRETATION The study did not identify an advantage of the 19G EBUS needle over the 21/22G EBUS needles for diagnostic yield nor sensitivity for sarcoidosis or lymphoma.

Randomized Cross-over Trial of Endobronchial Ultrasound Transbronchial Needle Aspiration With or Without Suction in Suspected Malignant Lymphadenopathy. J Bronchology Interv Pulmonol 2022; 29:131-139. [PMID: 34369402 DOI: 10.1097/lbr.0000000000000801] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Accepted: 07/06/2021] [Indexed: 11/25/2022]
Abstract
RATIONALE The benefit from applying suction during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is unclear. BACKGROUND The purpose of this study was to evaluate the impact of applying suction during EBUS-TBNA of lymph nodes (LN) on the diagnostic yield and specimen quality of EBUS-TBNA smears and cellblocks. METHODS We conducted a randomized blinded cross-over trial comparing the diagnostic yield and quality of EBUS-TBNA samples obtained with suction (S+) and without suction (S-) from suspected malignant mediastinal LN. Each LN was aspirated 4 times in a randomly assigned alternating order: S+/S-/S+/S- or S-/S+/S-/S+, resulting in 2 matched S+/S- smears pairs and 1 matched S+/S- cellblocks pairs. Specimen were assessed by a blinded cytopathologist. The primary outcome was the diagnostic yield of EBUS-TBNA smears and cellblocks. Secondary analyses accounted for LN size (≤2 vs. >2 cm) and station (mediastinal vs. hilar). RESULTS Of 234 EBUS-TBNA smears and 114 cellblocks were obtained from 59 LN. The concordance of S+ and S- cellblocks diagnostic yield was low (43.8%; 95% confidence interval: 30.7-57.6) with a significantly higher diagnostic yield among S+ compared with S- cellblocks (56.1% vs. 10.5%, respectively, P<0.001), regardless of LN station and size. However, S+ and S- smears were moderately concordant (66.7%; 95% confidence interval: 57.4-75.1) with no overall difference in their respective diagnostic yield. Numerically higher diagnostic yield among S+ smears in LN≤2 cm or hilar LN was not statistically significant. Results were similar for specimen adequacy, sensitivity and diagnosis of malignancy. CONCLUSION Applying suction during EBUS-TBNA of suspected malignant LN enhanced the diagnostic yield of cellblocks regardless of mediastinal LN station or size, but not of smears.

Abstract
Methods From May 2006 to January 2017, patients with mediastinal lymphadenopathy, who received an EUS-guided trucut biopsy or an FNA biopsy, were retrospectively reviewed. Demographic data, endosonographic characteristics of LNs including size, shape, border, echotexture, and echogenicity, diagnostic yield, and adverse events between the trucut needle group and aspiration needle group were compared. Results A total of 69 patients (trucut group, n = 33 vs. aspiration group, n = 36) were identified. There were no significant differences in demographic data, indication for an EUS-guided biopsy, location of LNs, number of needle passes, and endosonographic features of LNs between the two groups. The sizes of LNs were larger in the trucut group than in the aspiration group (28.9 ± 14.0 mm vs. 21.1 ± 8.8 mm, P = 0.007). However, there was no significant difference in the ratio of LNs that were ≥10 mm in both groups. The overall accuracy of the EUS-guided biopsy for the diagnosis of malignant lesions was 79.7% (55/69). There were no significant differences in the histological diagnostic yield of malignant LNs between the two groups. There were no significant procedure-related adverse events in both groups. Conclusion The EUS-guided biopsy can be a useful method for histologic evaluation of mediastinal nodal lesions.

Abstract
Aims and Objectives Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a precise modality for tissue sampling of mediastinal and hilar lesions adjacent to the proximal airway. This study aims to determine the diagnostic efficacy, sensitivity, and specificity of rapid-on site evaluation (ROSE) in EBUS-TBNA. Materials and Methods This is a retrospective study that included 100 patients who underwent EBUS-TBNA of paratracheal and mediastinal lymph nodes in a tertiary care hospital in South India between March 2018 and March 2020. After the procedure, the diagnostic yield from the nodes sampled was transferred to slides that were stained with rapid hematoxylin and eosin (H and E), and then onsite evaluation was done. The tissue derived was also processed for histopathologic examination in all cases. ROSE was performed to assess sample adequacy and to arrive at a preliminary diagnosis. In patients suspected of tuberculosis, the sample was collected for GeneXpert evaluation as well. Results Of the 100 cases studied, 51 were males and 49 were females. The age distribution was between 3 and 78 years. Forty-seven cases were diagnosed as granulomatous lymphadenitis, 13 as metastatic malignancies, 33 as reactive lymphadenitis, 3 as atypical cells, and 1 case was diagnosed as a cystic lesion. The diagnostic yield was not adequate for evaluation in three cases. Diagnostic yield was obtained in the first two passes where the lymph nodes were more than 2 cm in size. More diagnostic passes were required in lymph nodes less than 2 cm and those located between and adjacent to major vessels. The onsite diagnosis was correlated with the final histopathologic diagnosis. Conclusion ROSE serves as a useful adjunct to reduce procedure time and enhance sample collection and triaging, and reduces the need for further invasive testing.

Abstract
BACKGROUND Suction and capillary pull are 2 biopsy techniques used in endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Although these techniques have been shown to perform comparably in terms of overall diagnostic yield, we hypothesized that the capillary pull technique would be associated with improved rapid on-site evaluation (ROSE) adequacy rates thus allowing for a shorter procedure time. METHODS One hundred eighteen patients undergoing EBUS-TBNA for any indication were randomized to suction or capillary pull techniques for the first biopsy pass; the technique used for all subsequent passes was based on operator preference and was not recorded. The first pass was subjected to ROSE and an adequacy assessment was given. ROSE slides were also scored for cellularity of diagnostic/lesional cells and blood contamination. The overall procedure time was also recorded. RESULTS There were no significant differences between suction and capillary pull techniques in terms of ROSE adequacy rates. Cellularity of diagnostic/lesional cells and blood contamination scores were also comparable. There was no significant difference in procedure time for the 2 techniques. CONCLUSION This study suggests no differences in ROSE outcomes between suction and capillary pull techniques in EBUS-TBNA. The technique used should therefore be left to the discretion of the operator.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a safe and minimally invasive diagnostic tool for mediastinal and hilum evaluation. However, infectious complications may occur after EBUS-TBNA. Among these, mediastinitis and pericarditis are rare.
CASE SUMMARY A 67-year-old woman was referred to our hospital due to paratracheal lymph node enlargement on chest computed tomography (CT). EBUS-TBNA was performed on the lymph node lesions, and prophylactic oral antibiotics were administered. Seven days after EBUS-TBNA, the patient visited the emergency room with a high fever and chest pain. Laboratory test results revealed leukocytosis with a left shift and elevated C-reactive protein level (25.7 mg/dL). Chest CT revealed the formation of a mediastinal abscess in the right paratracheal lymph node and pericardial and bilateral pleural effusions. The patient received intravenous antibiotic treatment, cardiac drainage through pericardiocentesis, and surgical management. The patient recovered favorably and was discharged 31 d after the operation.
CONCLUSION Mediastinitis and pericarditis after EBUS-TBNA are rare but should be considered even after the use of prophylactic antibiotics.

Abstract
BACKGROUND Rapid on-site cytologic evaluation (ROSE) helps to improve the diagnostic accuracy in endobronchial ultrasound (EBUS) procedures. However, cytologists are seldom available to perform ROSE in many institutions. Recent studies have investigated the application of deep learning in cytologic image analysis. As such, the present study analyzed lung cytologic images obtained by EBUS procedures, and employed deep-learning methods to distinguish between benign and malignant cells and to semantically segment malignant cells. METHODS Ninety-seven patients who underwent 104 EBUS procedures were enrolled. Four hundred and ninety-nine lung cytologic images obtained via ROSE, including 425 malignant and 74 benign, and most malignant were lung adenocarcinoma (64.3%). All the images were used to train a residual network model with 101 layers (ResNet101), with suitable hyperparameters selected to classify benign and malignant lung cytologic images. An HRNet model was also employed to mark the area of malignant cells. Automatic patch-cropping was adopted to facilitate dataset preparation. RESULTS Malignant cells were successfully classified by ResNet101 with 98.8% classification accuracy, 98.8% sensitivity, and 98.8% specificity in patch-based classification; 95.5% classification accuracy in image-based classification; and 92.9% classification accuracy in patient-based classification. Malignant cell area was successfully marked by HRNet with a mean intersection over union of 89.2%. The automatic cropping method enabled the system to complete diagnosis within 1 s. CONCLUSIONS This is the first study to combine lung cytologic image deep-learning classification with semantic segmentation. The model was optimized for high accuracy and the automatic cropping facilitates the clinical application of our model. The success in both lung cytologic images classification and semantic segmentation on our dataset shows a promising result for clinical application in the future.

Abstract
OBJECTIVES Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become a standard procedure, but little is known about its infectious complications. The aim of this study is to evaluate the incidence and risk factors of infectious complications of EBUS-TBNA and its clinical course, including effects on anti-cancer treatment. METHODS This is a nested case-control study of patients who received EBUS-TBNA and were followed for at least 2 months at Samsung Medical Center from August 2009 to April 2019. Patients with clinical symptoms of infection and correlating chest images were defined as the infection group (n = 33). The controls were randomly selected from patients without infectious complication. Multivariate logistic regression with backward selection was used to identify the risk factors of infectious complications. RESULTS Of the 6826 patients, 33 (0.48%) infectious complications were identified, comprising pneumonia (n = 20) and mediastinal infections (n = 13). Target lesions with necrotic features on chest computed tomography (CT) scan (adjusted odds ratio [aOR], 3.08; 95% confidence interval [CI], 1.49-6.40; P = 0.002) and procedures that were performed via the esophagus (aOR, 3.19; 95% CI, 1.47-6.88; P = 0.003) were independently associated with infectious complications. Among patients ultimately diagnosed with cancer, the infection group tended to refuse anti-cancer treatment compared to controls (32/459, 7.0% vs. 5/30, 16.7%; P = 0.066). However, among the patients who received anti-cancer treatment, there was no delay in onset of treatment. CONCLUSIONS Infectious complications of EBUS-TBNA are rare; however, attention should be paid if the target lesion appears necrotic on chest CT or if the procedure is performed via the esophagus. Although it was not conclusive due to its rarity, patients with infectious complications tended not to receive anti-cancer treatment.

Erdogan-Durmus S. Diagnostic value of liquid-based cytology test in intrathoracic lymph nodes and lung lesions sampled by endobronchial ultrasonography-transbronchial needle aspiration. Diagn Cytopathol 2021; 49:1251-1256. [PMID: 34709736 DOI: 10.1002/dc.24898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 09/24/2021] [Accepted: 10/18/2021] [Indexed: 11/06/2022]
Abstract
BACKGROUNDS Liquid-based cytology (LBC) has begun to be used in non-gynecological samples such as endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). This study aims to investigate the diagnostic value of LBC in intrathoracic lymph nodes and lung lesions sampled with EBUS-TBNA. METHODS In total, 174 cases that underwent EBUS-TBNA between July 2020 and February 2021 were included (75 and 99 cases were prepared using conventional and LBC methods, respectively). The two groups were compared in terms of diagnostic categories, number of slides, cell blocks, slides per location, locations sampled, immunohistochemical studies, sensitivity, specificity, and diagnostic accuracy. RESULTS The percentages of malignant, suspicious for malignancy, benign, and non-diagnostic (ND) cases were 51.8%, 1.1%, 39.6%, and 7.5%, respectively. The LBC and conventional group (CG) had similar rates in the diagnostic categories, except for ND (3.0% and 13.3%, respectively). The sensitivity of LBC and CG were 90.4% and 85.7%, respectively. There were no differences in the specificity and diagnostic accuracy between groups. There was a statistically significant difference between groups in terms of the number of slides, number of slides per location, number of cell blocks, and locations sampled (p < .001, p < .001, p < .05, p < .05). CONCLUSION The LBC technique can be used for samples taken with EBUS-TBNA. Rapid fixation and the absence of artificial problems greatly reduce the rate of ND samples in LBC slides. Other important advantages are a lower number of slides to examine and a greater number of cell blocks.

Abstract
Background Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) allows precise real-time sampling of intrathoracic lesions and is a minimally invasive, safe, and cost effective technique with high diagnostic yield. The aim of the current study is to evaluate utility of EBUS-TBNA cytology with cellblocks (CBs) in the diagnosis and subtyping of the intrathoracic lesions. Materials and Methods It was a prospective study conducted from October 2015 to October 2017. We received 233 cases of intrathoracic lesions for EBUS-TBNA, of which CB was made in 217 cases. A flexible endobronchial ultrasound scope was used to sample the lesions. Results There were 89 females and 128 males amongst the total 217 patients (age range: 14-85 years, mean age: 48.35 years). The smears from EBUS-TBNA contained adequate material in 137/144 [95.1%] non-neoplastic cases and 34/36 [94.4%] of the neoplastic cases, whereas the CBs provided adequate material in 94/144 [65.3%] non-neoplastic cases and 37/40 [92.5%] neoplastic cases. The CB helped subtyping the malignancy in 19 cases and of these immunohistochemistry (IHC) was done on the CB in 15 cases. The biopsy was non-diagnostic in 17/36 cases of granulomatous pathology and 4/18 neoplastic cases diagnosed with EBUS-TBNA.3. Conclusions EBUS-TBNA provides rapid diagnosis through cytology and the material recovered in the same setting for the CB preparation can be used for immunohistochemical analysis and it may at times provide the diagnosis in cases where the smears are non-diagnostic.

Abstract
Endobronchial ultrasound (EBUS) bronchoscopy is an established minimally-invasive modality for visualization, characterization, and guidance of sampling of paratracheal and parabronchial structures and tissues. In the intensive care unit (ICU), rapidly obtaining an accurate diagnosis is paramount to the management of critically ill patients. In some instances, diagnosing and confirming terminal illness in a critically ill patient provides needed closure for patients and their loved ones. Currently available data on feasibility, safety, and yield of EBUS bronchoscopy in critically ill patients is based on single center experiences. These data suggest that in select ICU patients convex and radial probe-EBUS bronchoscopy can serve as useful tools in the evaluation of mediastinal lymphadenopathy, central airway obstruction, pulmonary embolism, and peripheral lung lesions. Barriers to the use of EBUS bronchoscopy in the ICU include: (I) requirement for dedicated equipment, prolonged procedure time, and bronchoscopy team expertise that may not be available; (II) applicability to a limited number of patients and conditions in the ICU; and (III) technical difficulty related to the relatively large outer diameter of the convex probe-EBUS bronchoscope and an increased risk for adverse cardiopulmonary consequences due to intermittent obstruction of the artificial airway. While the prospects for EBUS bronchoscopy in critically ill patients appear promising, judicious patient selection in combination with bronchoscopy team expertise are of utmost importance when considering performance of EBUS bronchoscopy in the ICU setting.

Abstract
Sarcoidosis is a multisystem disorder of unknown origin and poorly understood pathogenesis that predominantly affects lungs and intrathoracic lymph nodes and is characterized by the presence of noncaseating granulomatous inflammation in involved organs. The disease is highly heterogeneous and can mimic a plethora of other disorders, making diagnosis a challenge even for experienced physicians. The evolution and severity of sarcoidosis are highly variable: many patients are asymptomatic and their disease course is generally benign with spontaneous resolution. However, up to one-third of patients develop chronic or progressive disease mainly due to pulmonary or cardiovascular complications that require long-term therapy. The diagnosis of sarcoidosis requires histopathological evidence of noncaseating granulomatous inflammation in one or more organs coupled with compatible clinical and radiological features and the exclusion of other causes of granulomatous inflammation; however, in the presence of typical disease manifestations such as Löfgren’s syndrome, Heerfordt’s syndrome, lupus pernio and asymptomatic bilateral and symmetrical hilar lymphadenopathy, the diagnosis can be established with high level of certainty on clinical grounds alone. This review critically examines the diagnostic approach to sarcoidosis and emphasizes the importance of a careful exclusion of alternative diagnoses.

High Diagnostic Accuracy and Safety of Endoscopic Ultrasound-Guided Fine-Needle Aspiration in Malignant Lymph Nodes: A Systematic Review and Meta-Analysis. Dig Dis Sci 2021; 66:2763-2775. [PMID: 32979158 DOI: 10.1007/s10620-020-06554-2] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2020] [Accepted: 08/10/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND AND AIMS Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is increasingly being used for diagnosing lymphadenopathy. We aim to systematically review the accuracy of EUS-FNA in differentiating benign and malignant mediastinal and abdominal lymph nodes (LNs). METHODS A comprehensive literature search was performed on multiple electronic databases through February 2020. A random or fixed effect model generated the pooled sensitivity, specificity, likelihood ratio (LR), and diagnostic odds ratio (DOR) of EUS-FNA. Subgroup analyses and meta-regression were used to explore sources of heterogeneity. RESULTS Twenty-six studies involving 2753 patients with 2833 LNs were included. In the differential diagnosis of benign and malignant LNs, EUS-FNA had a pooled sensitivity, specificity, positive LR, and negative LR of 87% (95% confidence interval [CI] 86-90%), 100% (95% CI 99-100%), 68.98 (95% CI 42.10-113.02), and 0.14 (95% CI 0.11-0.17), respectively. The pooled rate of adverse events associated with EUS-FNA was 1.57% (95% CI 1.06-2.24%). The summary receiver operating characteristic (SROC) yielded an area under the curve (AUC) of 0.9912. EUS-FNA performed in mediastinal LNs gained a sensitivity of 85% (95% CI 81-88%), while in abdominal LNs, it reached 87% (95% CI 82-91%). The sensitivity of the subgroup with rapid on-site evaluation (ROSE) was 91% (95% CI 89-93%), while non-ROSE was 85% (95% CI 82-87%). CONCLUSIONS EUS-FNA is a sensitive, highly specific, and safe method for distinguishing benign and malignant mediastinal or abdominal LNs. However, the sensitivity of EUS-FNA still varies significantly among different centers.

Abstract
Background The difference in patient comfort with conscious sedation versus general anaesthesia for bronchoscopy has not been adequately assessed in a randomised trial. This study aimed to assess if patient comfort during bronchoscopy with conscious sedation is noninferior to general anaesthesia. Methods 96 subjects were randomised to receive conscious sedation or general anaesthesia for bronchoscopy. The primary outcome was subject comfort. Secondary outcomes included willingness to undergo a repeat procedure if necessary and level of sedation assessed clinically and by bispectral index (BIS) monitoring. Results There was no significant difference between subject comfort scores (difference -0.01, 95% CI -0.63-0.61 on a 10-point scale; p=0.97) or willingness to undergo a repeat procedure (97.7% versus 91.8%, 95% CI -4.8-15.5%; p=0.37). Deeper levels of sedation in the general anaesthesia cohort was confirmed with both clinical and BIS monitoring. There was no significant difference in diagnostic accuracy (conscious sedation 93.9%, 95% CI 80.4-98.3% versus general anaesthesia 86.5%, 95% CI 72.0-94.1%; p=0.43). There were more complications (29.6%, 95% CI 18.2-44.2% versus 6.1%, 95% CI 2.1-16.5%; p<0.01) in the general anaesthesia group. There was no relationship between high BIS scores and subject discomfort. BIS levels <40 during a procedure were associated with increased complications. Conclusion Conscious sedation is not inferior to general anaesthesia in providing patient comfort during bronchoscopy, despite lighter sedation, and is associated with fewer complications and comparable diagnostic accuracy. BIS monitoring may have a role in preventing complications associated with deeper sedation.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is useful for diagnosing hilar and mediastinal lymph node enlargement; however, specimens obtained are often small and inadequate for pathologic diagnosis. In June 2017, EchoTip ProCore, a puncture needle with a side trap, was launched in Japan. In this single-center prospective interventional study, 57 patients with lymph nodes, intrapulmonary tumor or pleural mass were diagnosed using EBUS-TBNA with EchoTip ProCore between June 2017 and February 2020. EBUS-TBNA was performed for 57 patients and 53 patients had sufficient specimen for histologic diagnosis. The following pathologic subtypes were diagnosed: non-small cell lung cancer, 22; small cell lung cancer, 8; cancer of unknown primary, 2; neuroendocrine tumor (G2) recurrence, 1; lymphoma, 2; metastatic renal cell carcinoma, 3; thymoma recurrence, 1; sarcoidosis, 4; tuberculosis, 1; and non-malignancy, 9. In addition, the cytology showed Class V in 31 out of 57 cases (54.4%). In total, a definitive pathological diagnosis was obtained in 50 out of 57 cases (87.7%). The only complication was pneumonia caused by BAL simultaneously combined with EBUS-TBNA in one patient. Among 13 patients with inadequate specimens or without malignancy, only one patient was subsequently diagnosed with malignancy, and the median follow-up period was 300 days. EBUS-TBNA using EchoTip ProCore can obtain a sufficient specimen size for pathologic diagnosis.

Abstract
PURPOSE EBUS-TBNA is a frequently used diagnostic method for mediastinal/hilar lymphadenopathies and masses. This procedure is performed with intravenous sedation (IVS). During IVS, patients often develop hypoxemia and nasal oxygen delivery is insufficient in some patients. The aim of this study was to investigate the effect of oxygen application with nCPAP on hypoxemia during EBUS-TBNA. METHODS Patients with EBUS-TBNA indication who did not have any serious heart-lung disease were randomly divided into two groups. One group received only oxygen and the other group received nCPAP+oxygen. Patient characteristics, arterial oxygen saturations, anesthetic agents, CPAP pressures, oxygen concentrations and processing times were recorded during the procedure. Practitioner satisfaction was evaluated at the end. RESULTS 29 nCPAP+oxygen, 31 oxygen patients were included in the study. There were no significant differences in terms of age, sex, smoking history and presence of additional diseases in two groups. Neck circumference, BMI and STOP BANG questionnaire values were similar. Desaturation time was significantly longer in oxygen group than nCPAP+oxygen group (316±390 sec, 12±118 sec, respectively, p=0,019). Snoring was detected during the procedure in 22 patients in the oxygen group and in 11 patients in the nCPAP group (p=0,01). There were no serious complications in both groups. Practitioner satisfaction was higher in the nCPAP group but this was not statistically significant (p=0,052). CONCLUSION Oxygen application by nCPAP during EBUS-TBNA under IVS, significantly reduces desaturation time. Oxygen delivery with nCPAP seems to be a better choice especially for the patients with high Mallampati index.

Abstract
OBJECTIVES Endobronchial ultrasound- and endoscopic ultrasound-guided fine-needle aspiration (EBUS-/EUS-FNA) are minimally invasive techniques of diagnosing and staging malignancies. The procedures are difficult to master, requiring specific feedback for optimizing yield. METHODS Over 2 years, EBUS-/EUS-FNA cases were gathered using the institutional pathology database. Patient and specimen characteristics were collected from the pathology database and electronic medical record. RESULTS In 2 years, 789 unique FNA specimens were collected (356 EBUS and 433 EUS specimens). The cohort and each subgroup had excellent performance, which was enhanced by telepathology. The discrepancy rate was satisfactorily low. Hematolymphoid neoplasms are overrepresented in discrepant EBUS cases. The malignancy rates of cytology diagnostic categories were comparable to the literature. CONCLUSIONS Using diagnostic yield and concordance results allow for comprehensive evaluation of the entire process of EBUS-/EUS-FNAs. This study's findings can influence patient management, training methods, and interpretation of results, while also acting as a model for others to investigate their own sources of inadequacy, discrepancy, and training gaps.

Diagnostic utility of rapid on-site evaluation of endobronchial ultrasound-guided transbronchial needle aspiration samples: A study in a region of high tuberculosis burden. Cytopathology 2021; 32:428-435. [PMID: 33848034 DOI: 10.1111/cyt.12975] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Revised: 02/28/2021] [Accepted: 03/12/2021] [Indexed: 11/30/2022]
Abstract
INTRODUCTION Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a very useful tool for precise diagnosis of thoracic lesions. However, the procedure sometimes has a poor yield. Rapid on-site evaluation (ROSE) in EBUS-TBNA has been shown to be helpful to improve its diagnostic yield and minimise the need for repeat procedures. Most of the studies that have evaluated the utility of ROSE have focused on malignant lesions; however, it is important to understand its utility in benign lesions, particularly in a country with a high tuberculosis burden. OBJECTIVE This study was undertaken to evaluate the utility of ROSE in EBUS-TBNA for the diagnosis of patients presenting with mediastinal lymphadenopathy and/or thoracic mass for benign and malignant pathologies. METHODS This was a prospective study including 47 patients who underwent EBUS-TBNA for thoracic lesions (lung masses and hilar/mediastinal lymphadenopathy) over a 10-month period at a single tertiary care centre. In addition to ROSE and definitive cytology, the aspirated material was also sent for cell block and microbiological studies. Endobronchial/transthoracic biopsy was conducted for histopathological evaluation (HPE) where required, at the discretion of the clinician. ROSE diagnosis was then compared with the final diagnosis. RESULTS Of the 47 patients examined using ROSE, granulomas were observed in 33 cases, non-specific inflammation in six cases, and malignancy in five cases; one case was inconclusive and the sample was found to be inadequate in two cases. The ROSE assessment matched the final diagnosis in 84.45% patients. CONCLUSION ROSE is a simple procedure that is able to provide an immediate and accurate assessment of adequacy and has a significant yield, enabling a preliminary diagnosis to be made in both benign and malignant samples.

Performance insights of endobronchial ultrasonography (EBUS) and mediastinoscopy for mediastinal lymph node staging in lung cancer. Lung Cancer 2021; 156:122-128. [PMID: 33931293 DOI: 10.1016/j.lungcan.2021.04.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 03/28/2021] [Accepted: 04/02/2021] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Endobronchial Ultrasonography (EBUS) and mediastinoscopy are used for mediastinal lymph node staging in patients with suspected non-small cell lung carcinoma (NSCLC). In our hospital, confirmatory mediastinoscopy has been largely abandoned, which may reduce the number of surgical interventions and health care costs. This study provides insight into EBUS and mediastinoscopy performance in patients with proven NSCLC from January 2007 until January 2019. METHODS This is a single-centre, retrospective study, evaluating unforeseen N2 rates, negative predictive value and survival, providing insight into the diagnostic yield of EBUS and mediastinoscopy. Surgical lung resection with lymph node dissection was used as reference. RESULTS A total of 418 patients with proven NSCLC after lung resection (mean age: 66 years; 61 % male) and 118 patients who underwent mediastinoscopy, have been included in the study. The overall prevalence of N2 metastases after lung resection was 10.5 %. The percentage of unforeseen N2 cases after negative EBUS was 14.5 %, and 14.3 % after negative mediastinoscopy. Over the past nine years, none of the confirmatory mediastinoscopies were tumor positive after negative EBUS results. The median survival in patients with surgically confirmed N2 metastases was 33 months, compared to 23 months in patients with EBUS/mediastinoscopy-proven N2 metastases. CONCLUSION Despite optimisation of mediastinal staging procedures, it remains difficult to identify all patients with N2 metastases in the workup of NSCLC. In our institute, confirmatory mediastinoscopy has no added value after tumor-negative EBUS procedures, and has been abandoned as standard procedure.

Abstract
BACKGROUND In the last decade, the advent of thoracic endosonography has revolutionised the field of diagnostic bronchoscopy. METHODS We conducted a single-centre prospective study in "Sotiria" Chest diseases hospital between January 2016 and December 2019. The study aimed to evaluate the efficacy and diagnostic value of combined EBUS/EUS-b in comparison with EBUS-TBNA and EUS-b FNA in different intrathoracic diseases. RESULTS A total of 266 patients were enrolled (70.7% males, 85.7% smokers, mean age ± SD: 62.8 ± 11.8). Diagnosis and staging of suspected lung cancer (LC) were the main indications for EBUS/EUS-b in 56.7% of patients, followed by lymphadenopathy of unknown origin in 27%, lymphadenopathy in previous malignancy in 10.9%, and staging of proven LC in 5.3%. EUS-b FNA alone or combined with EBUS-TBNA was performed in 14.7% of patients. A total of 512 lymph nodes was sampled (481 through EBUS-TBNA and 31 through EUS-b FNA). EBUS/EUS-b led to a definitive diagnosis in 68.4% of the patients. Most cases (50.4%) were malignancies, while 18% represented benign diseases (83.3% sarcoidosis). Sensitivity of combined EBUS/EUS-b was higher in comparison with sensitivity of both procedures alone (100% vs 89.4% vs 88.9%). Accordingly, the overall sensitivity of EBUS/EUS-b for the detection of malignancy and sarcoidosis was 93% and 95.2%, respectively. No severe complications were observed. CONCLUSION Thoracic endosonography is an efficient, safe, minimally invasive tool yielding high sensitivity and diagnostic accuracy in patients with suspected malignancy and mediastinal lymphadenopathy. Experienced pulmonologists in EBUS-TBNA should more routinely perform EUS-b FNA to avoid unnecessary surgical interventions.

Abstract
Background and Objectives: Along with the rapid improvement of imaging technology, convex probe endobronchial ultrasound (CP-EBUS) sonographic features play an increasingly important role in the diagnosis of intrathoracic lymph nodes (LNs). Conventional qualitative and quantitative methods for EBUS multimodal imaging are time-consuming and rely heavily on the experience of endoscopists. With the development of deep-learning (DL) models, there is great promise in the diagnostic field of medical imaging. Materials and Methods: We developed DL models to retrospectively analyze CP-EBUS images of 294 LNs from 267 patients collected between July 2018 and May 2019. The DL models were trained on 245 LNs to differentiate benign and malignant LNs using both unimodal and multimodal CP-EBUS images and independently evaluated on the remaining 49 LNs to validate their diagnostic efficiency. The human comparator group consisting of three experts and three trainees reviewed the same test set as the DL models. Results: The multimodal DL framework achieves an accuracy of 88.57% (95% confidence interval [CI] [86.91%–90.24%]) and area under the curve (AUC) of 0.9547 (95% CI [0.9451–0.9643]) using the three modes of CP-EBUS imaging in comparison to the accuracy of 80.82% (95% CI [77.42%–84.21%]) and AUC of 0.8696 (95% CI [0.8369–0.9023]) by experts. Statistical comparison of their average receiver operating curves shows a statistically significant difference (P < 0.001). Moreover, the multimodal DL framework is more consistent than experts (kappa values 0.7605 vs. 0.5800). Conclusions: The DL models based on CP-EBUS imaging demonstrated an accurate automated tool for diagnosis of the intrathoracic LNs with higher diagnostic efficiency and consistency compared with experts.

Abstract
AIM Complication rates are low and endobronchial ultrasound guided needle aspiration (EBUS-TBNA) is generally regarded as a safe procedure, but there is a very limited number of studies evaluating the efficacy and safety of the procedure in advanced ages. The aim of this study is to assess the safety and performance outcomes of EBUS-TBNA in elderly. METHODS It was a retrospective observational study; patients who received EBUS-TBNA between September 2016 and January 2018 were evaluated. We analyzed patient's characteristics, doses of midazolam, and lidocaine used, regions of lymph node biopsies, and complications. Also, functionality and general physical status of patients over 65 years of age were evaluated. RESULTS During study period 132 cases of EBUS-TBNA were evaluated. 39 (29.5%) cases were aged 70 years, and over. There were more comorbidities in older group. Performance status of older group was worse. Furthermore, when evaluated according to American College of Cardiology (ACC)/American Heart Association (AHA) and American Society of Anesthesiologists (ASA), the older group was found to be composed of the riskier patients. When patients aged between 65 and 69, and over 70 compared, older patient's Barthel, EQ 5-D, SGA, and G8 scores were found to be worse. Despite that, there was no difference in the frequency, and types of complications between both groups. Diagnostic performance was not different between age groups. CONCLUSIONS Independent from comorbidities, general health status, and functionality EBUS-TBNA procedure in 70-year-old and over patients is a safe minimally invasive procedure.

Abstract
Mediastinitis by endobronchial ultrasound-guided transbronchial needle aspiration. EBUS-related mediastinitis is treated effectively by surgical drainage. Combination of surgery and medical treatment can be very effective in the treatment of inflammation caused by EBUS.
We report two cases of severe mediastinitis accompanied by abscess due to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), that were successfully treated by effective surgical drainage. A 68-year-old woman was referred to our hospital due to chest discomfort and high fever after EBUS-TBNA, and a 54-year-old man was referred due to general weakness, chills, and high fever after the same procedure. Both were diagnosed with EBUS-related mediastinitis and discharged after surgical treatment. Similar to previous reports, the importance of surgical procedures for mediastinitis caused by EBUS-TBNA was suggested. Further research and establishment of guidelines on this matter is necessary.

Abstract
Background Sonographic findings of lymph nodes on endobronchial ultrasonography (EBUS) images have been reported to be useful to predict lymph node metastasis (LNM) in lung cancer patients. F-18 fluorodeoxyglucose (FDG) uptake in lymph nodes was also found to be useful. In this study, we aimed to clarify whether a combination of sonographic features and maximum standardized uptake values of lymph nodes (LN-SUVmax) is useful for predicting LNM in lung cancer patients. Methods From January 2014 to December 2019, a total of 147 lymph nodes from 104 patients with lung cancer, who underwent preoperative EBUS and FDG-positron emission tomography (PET)/computed tomography (CT) followed by surgery were retrospectively assesses. The characteristics of the patients, LN-SUVmax, and sonographic findings of lymph nodes were reviewed. Predictive factors associated with LNM were identified using the logistic regression model. Results The average size of the lymph nodes was 8.55 (range, 3–22) mm and the average LN-SUVmax was 5.36 (range, 1.79–31.19). The prevalence of nodal metastasis was 26/147 (17.4%), including 22 in mediastinal lymph nodes and 4 in hilar lymph nodes. Multivariate analysis demonstrated four independent predictive factors for LNM; size, round or oval shape, absence of a central hilar structure, and LN-SUVmax. The optimal cutoff value for lymph node size and LN-SUVmax were 10 mm and 6.00, respectively. By combinating of the two modalities, we obtained the results with sensitivity of 76.9%, specificity of 95.1% and accuracy of 93.2%. Conclusions A combination of sonographic findings and LN-SUVmax showed a higher diagnostic rate of LNM than either modality alone in lung cancer patients.

Abstract
Screening for lung cancer has changed substantially in the past decade since The National Lung Screening Trial. The resultant increased discovery of incidental pulmonary nodules has led to a growth in the number of lesions requiring tissue diagnosis. Bronchoscopy is one main modality used to sample lesions, but peripheral lesions remain challenging for bronchoscopic biopsy. Alternatives have included transthoracic biopsy or operative biopsy, which are more invasive and have a higher morbidity than bronchoscopy. In hopes of developing less invasive diagnostic techniques, technologies have come to assist the bronchoscopist in reaching the outer edges of the lung. Navigational bronchoscopy is able to virtually map the lung and direct the biopsy needle where the scope cannot reach. Robotic bronchoscopy platforms have been developed to provide stability and smaller optics to drive deeper into the bronchial tree. While these new systems have not yet proven better outcomes, they may reduce the need for invasive procedures and be valuable armamentarium in diagnosing and treating lung nodules, especially in the periphery.

Abstract
SETTING Although endobronchial ultrasonography-transbronchial needle aspiration (EBUS-TBNA) has a well-known place in the staging and diagnosis of lung cancer, the place of EBUS is not clear in the diagnosis of benign diseases, especially in countries with a high prevalence of tuberculosis. AIM The aim of this study is to investigate the diagnostic efficacy of EBUS-TBNA in benign diseases in a population with a high prevalence of tuberculosis. MATERIAL AND METHODS Between October 2011 and March 2018, 1077 EBUS-TBNA was applied. RESULTS The diagnosis was reached with mediastinoscopy or video assisted thoracic surgery (VATS) in 41 (74.5%) and with the second EBUS-TBNA performed in 14 (25.5%) of 55 EBUS practices in 41 patients with malignancy diagnosis. The final diagnosis was achieved with clinical/radiological features in 7 (77.7%) cases of sarcoidosis, with VATS/mediastinoscopy in 2 (22.2%) cases, with EBUS-TBNA performed for the second time in 6 (54.5%) tuberculosis cases and with acid-resistance bacilli reproduction in Lowenstein-Jensen culture in 5 (45.4%) cases. Two hundred and ninety-five (79.7%) patients were accepted as "benign disease" due to the absence of radiological and clinical progression of lesions in the follow-up. CONCLUSION The diagnostic accuracy of EBUS-TBNA is high in benign diseases such as sarcoidosis and tuberculosis.

Thrombolysis of Pulmonary Emboli via Endobronchial Ultrasound-Guided Transbronchial Needle Injection. Ann Thorac Surg 2020; 112:395-404. [PMID: 33941356 DOI: 10.1016/j.athoracsur.2020.08.043] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2020] [Revised: 07/30/2020] [Accepted: 08/31/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle injection (EBUS-TBNI) is a novel technique for treating peribronchial targets. The aim of this study was to evaluate preliminary feasibility of thrombolysis of pulmonary emboli via EBUS-TBNI. METHODS Yorkshire pigs (30-48 kg) were anesthetized and mechanically ventilated. Pre-formed autologous clots were injected sequentially into bilateral lower pulmonary arteries in bilateral models (PE1 and PE2, respectively) or into 1 side in unilateral models using a 21-gauge EBUS-TBNA needle under EBUS guidance. In the bilateral model, 2 hours after clot injection either 25 mL of tissue-plasminogen activator (t-PA; 1mg/mL) or distilled water were administered into each embolus via 25-gauge EBUS-TBNA needle. In the unilateral model, 25 mg t-PA was administered intravenously. Hemodynamic parameters were monitored continuously, and clot dissolved volume was evaluated by EBUS 30 minutes post-treatment administration. RESULTS All clots (6.1 ± 1.7 mL) were successfully injected as documented by EBUS Doppler imaging. Clot injection in the bilateral model (n = 6) increased pulmonary arterial pressure (mm Hg: Baseline 19.2 ± 5.9 vs PE1: 26.7 ± 9.1, P = .005 vs PE2 29.9 ± 7.1, P = .0007). After t-PA TBNI in the bilateral model (n = 6), pulmonary arterial pressure at 30 minutes post-injection showed improvement (mm Hg: PE2 29.9 ± 7.1 vs post-t-PA 24.4 ± 3.9, P = .0283). Treatment with t-PA TBNI demonstrated superior clot dissolution at 30 minutes post-treatment (dissolved mm3: t-PA TBNI 625.4 ± 156.6 vs t-PA intravenously: 181.6 ± 94.3, P = .0003 vs distilled water TBNI 42.5 ± 33.0, P < .0001). There were no complications. CONCLUSIONS EBUS-guided transbronchial thrombolysis may be a feasible approach for treating central pulmonary emboli.

Clinical utility of thoracic endosonography (EBUS/EUS-b) in mediastinal staging of patients with non-small cell lung cancer: comparison with integrated PET/CT-a real-life prospective study in Greece. J Thorac Dis 2020; 12:5657-5666.

Abstract
Background Accurate mediastinal staging in patients with non-small cell lung cancer (NSCLC) is crucial for the determination of optimal treatment management. Methods This was a real-life prospective study enrolling 140 patients between December 2016 and August 2018. We aimed to determine the clinical utility of EBUS/EUS-b in mediastinal staging of patients with NSCLC in comparison with integrated PET/CT. Furthermore, SUVmax cut-off value with the highest specificity/accuracy was evaluated. Subgroup analysis according to histological type was performed. Results One hundred and thirty patients were eligible for analysis (mean age ± SD: 67.6±7.6, males 97). Three hundred different lymph node stations were sampled (272 through EBUS-TBNA and 28 through EUS-b FNA). Mean SUVmax of all malignant lymph nodes was 7.46 (SD =5.54). Sensitivity, specificity, PPV and NPV of EBUS/EUS-b for the identification of mediastinal malignant lymph nodes was 93.8%, 100%, 100%, and 93.4%, respectively. Accordingly, PET/CT yielded 92.2% sensitivity, 43.9% specificity, 64.8% PPV and 83.3% NPV. For adenocarcinoma (n=76) NPV were 86.2% with EBUS/EUS-b and 75% with PET/CT. NPV for squamous cell (n=46) was 100% with EBUS/EUS-b and 90.9% with PET/CT. EBUS/EUS-b staging yielded excellent agreement with final staging (97.5%, Tau 0.94, P<0.001). ROC curve analysis identified the value 4.95 as the optimal SUVmax cut-off value with the best specificity (87.4%) and accuracy (79%) (AUC 0.69; 95% CI: 0.73-0.84, P<0.001). Conclusions Thoracic endosonography is an excellent, minimally invasive tool yielding high sensitivity and diagnostic accuracy in mediastinal staging of patients with NSCLC. Implementation of both EBUS/EUS-b and PET/CT is necessary before any surgical intervention.
