Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is valuable for diagnosing pulmonary sarcoidosis. We aimed to evaluate the diagnostic yield of EBUS-TBNA and cytology in sarcoidosis during the first 9 years at our institution. METHODS Patients who underwent EBUS-TBNA for suspected sarcoidosis between January 2011 and November 2019 were identified retrospectively. EBUS-TBNA was performed with rapid on-site cytological evaluation of the samples. The final diagnosis was based on the pathology and/or cytology results, radiologic features, and clinical follow-up findings. The yield rate was analyzed annually. RESULTS Eighty patients underwent 83 EBUS-TBNA procedures for suspected sarcoidosis. In total, 136 lymph nodes were sampled. The mean number of lymph node stations sampled was 2.0 ± 0.6; the mean number of needle passes per lymph node was 3.5 ± 0.8. Sixty-five patients were diagnosed with sarcoidosis, with a total of 68 procedures. Nonnecrotizing granulomatous inflammation was detected in the EBUS-TBNA samples from 49/68 procedures (yield rate: 72.1%). Of 19 patients with sarcoidosis who did not obtain a pathological diagnosis with EBUS-TBNA, epithelioid cells and/or multinuclear giant cells suggestive of granulomatous inflammation were detected in five. The sensitivity, specificity, positive predictive value, and negative predictive value (NPV) for pathological diagnosis of sarcoidosis using EBUS-TBNA were 72.1%, 100%, 100%, and 24.0%, respectively. On using cytology, the sensitivity and NPV increased to 79.4% and 26.3%, respectively. The yield rate did not increase until 2016. CONCLUSION EBUS-TBNA is useful for diagnosing sarcoidosis. Cytology resulted in an additional yield rate of 7.3%, which improved as the number of cases increased.

Abstract
Mediastinal lymphadenopathy is a condition in which one or more mediastinal lymph nodes are enlarged for malignant or benign causes, generally more than 10 mm. For a long time, the only way to approach the mediastinum was surgery, while in last decades endoscopic techniques gained their role in neoplastic diseases. At the present time, EBUS is the technique of choice for studying the mediastinum in the suspicion of cancer, while there are not strong indications in guidelines for the study of benign mediastinal lymphadenopathy. We reviewed the literature, looking for evidence of the role of EBUS in the diagnostics of non-neoplastic mediastinal lymphadenopathy, with special regard for granulomatous disease, both infectious and non-infectious. EBUS is a reliable alternative to surgery in non-neoplastic mediastinal lymphadenopathy, even if more evidence is needed for granulomatous diseases other than tuberculosis and sarcoidosis.

Abstract
Background: Sarcoidosis is a multisystem disease characterized by noncaseating granulomatous inflammation that most commonly involves the lungs. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become an invaluable tool in the assessment of patients with mediastinal and/or hilar lymphadenopathy. Objective: It has been hypothesized that use of the larger 19-gauge (G) needle with EBUS-TBNA improves diagnostic sensitivity in sarcoidosis. However, it is unclear whether the existing literature supports this supposition. Data Sources: A literature search of Embase and Medline was performed by two reviewers. Included articles were evaluated for bias using the QUADAS-2 tool. Data Extraction: For quantitative analysis, we performed a meta-analysis using a binary random-effects model to determine pooled sensitivity. Subgroup analysis was performed based on needle size, use of rapid on-site evaluation (ROSE), study design, and prevalence of sarcoidosis in study group. Synthesis: Sixty-five studies with a total of 4,242 patients were included in the meta-analysis. Overall pooled sensitivity for diagnosis of sarcoidosis was 83.99% (95% confidence interval [CI], 81.22-86.53) among all studies. The 19G subgroup had a significantly higher sensitivity (93.73%; 95% CI, 89.72-97.74%; I2 = 0.00%; P < 0.01) compared with the 21G subgroup (84.61%; 95% CI, 78.80-90.42%; I2 = 69.83%), 22G subgroup (84.07%; 95% CI, 80.90-87.24%; I2 = 85.21%) or unspecified 21G/22G subgroup (78.85%; 95% CI, 70.81-86.90%; I2 = 84.47%). There were no significant differences with use of ROSE or prevalence of sarcoidosis or by study design. Conclusions: The use of 19G needles during EBUS-TBNA had the highest diagnostic sensitivity based on available studies. Further randomized controlled trials using 19G needles should be considered in patients with suspected sarcoidosis.

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
Sarcoidosis (SA) is a systemic granulomatous disorder of unknown etiology with lung and mediastinal lymph nodes (LNs) as the main location. T lymphocytes play important role in the formation of granulomas in SA, but still little is known about the role of maturation profile in the development of inflammatory changes. The aim of this study was to determine the CD4+ and CD8+ T cells maturation profile in LNs and in peripheral blood (PB) and its relation to disease severity expressed by diffusing capacity of the lung for carbon monoxide (DLCO). 29 patients with newly pulmonary SA were studied. Flow cytometry was used for cells evaluation in EBUS-TBNA samples. We observed lower median proportion of T lymphocytes, CD4+ T and CD8+ T cells in patients with DLCO< 80% than in patients with normal diffusion (DLCO > 80%). Patients with DLCO < 80% had lower median proportion of effector and higher median proportion of central memory CD4+ and CD8+ T cells than patients with DLCO > 80%. We reported for the first time that LNs CD4+ and CD8+ T cells maturation differs depending on the DLCO value in sarcoidosis. Lymphocytes profiles in LNs may reflect the immune status of patients with SA and can be analysed by flow cytometry of EBUS-TBNA samples.

Abstract
INTRODUCTION Lung cancer is the most common cancer in the world, both in terms of new cases and deaths. Almost a fifth of all cancer deaths worldwide are due to lung cancers. Our aim was to evaluate the utility of endobronchial ultrasound-guided trans-bronchial needle aspiration (EBUS-TBNA) for lymph node staging in patients with lung cancer. METHODS We performed a retrospective study on a total of 427 patients who underwent EBUS-TBNA sampling from January 2020 to December 2020 and a total of 610 lymph nodes were sampled. There were 322 men (mean age: 66.3 and range: 20-87) and 105 women (mean age: 65.9 and range: 18-81). RESULTS Cytological diagnosis revealed that 55 patients had adenocarcinoma, 28 squamous cell carcinoma, 43 neuroendocrine tumours, 34 non-small cell carcinoma not otherwise specified, 21 metastasis from extra-thoracic malignancy, 7 atypical cells suspicious for malignancy, and 239 patients had normal or reactive lymph nodes or non-neoplastic diagnosis. The diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 91%, 88.3%, 100%, 100% and 89.2%, respectively. CONCLUSION EBUS-TBNA is a safe technique with high accuracy, sensitivity, specificity, PPV, and NPV. It is an excellent option for the diagnostic approach of patients with lymphadenopathy or intra-thoracic lesions as well as for the staging of malignancies.

Abstract
BACKGROUND Endobronchial ultrasound (EBUS) guided intranodal forceps biopsy (IFB) is considered complimentary to EBUS-TBNA for patients with intrathoracic lymphadenopathy when either additional tissue is requested for comprehensive molecular testing, or for suspected lymphoma and sarcoidosis. This is a systematic review and meta-analysis to investigate the diagnostic yield and complications of combined EBUS-IFB and EBUS-TBNA compared to EBUS-TBNA alone. METHODS We performed a systematic search of MEDLINE, Embase, and Google Scholar for studies evaluating the use of EBUS-IFB for diagnosis of intrathoracic adenopathy, assessing the quality of each study using the QUADAS-2 tool. Using inverse-variance weighting, we performed a meta-analysis of diagnostic yield estimations. We also reviewed the complications related to the procedure. RESULTS Six observational studies with 443 patients undergoing 467 biopsies were included in the final analysis. Meta-analysis yielded a pooled overall diagnostic yield of 67% (312/467) for EBUS-TBNA and 92% (428/467) for EBUS-TBNA + EBUS-IFB, with an inverse variance - weighted OR of 5.87 (95% CI, 3081 to 9.04, p<0.00001) and an I 2of 15%. The overall complications included pnuemomediastinum (1%), bleeding (0.8%) and respiratory failure (0.6%). The funnel plot analysis illustrated no major publication bias. Subgroup analysis showed increased diagnostic yield for lymphoma (86% vs 30%, p=0.03) and sarcoidosis (93% vs 58%, p<0.00001). CONCLUSIONS The addition of EBUS-IFB to EBUS-TBNA improves the overall diagnostic yield of sampling intrathoracic adenopathy when compared to EBUS-TBNA alone. The complication rates of the combined approach are higher than with EBUS-TBNA, but are reportedly lower than with transbronchial or surgical biopsies.

Abstract
INTRODUCTION Diagnosis of sarcoidosis is based on clinical status and radiologic specific findings. Tissue confirmation of noncaseating granulomas is crucial. Pathological confirmation of pulmonary sarcoidosis is most commonly accomplished by bronchoscopy, which has a diagnostic yield of approximately 60%-70%. OBJECTIVES In this prospective study, we analysed potential benefit of EBUS-TBNA and EBB combination, application of cell blocks and smears with puncturing more than one station of lymph nodes in order to determine optimal strategy in diagnosis of sarcoidosis. METHODS About 133 patients with suspicion of sarcoidosis (stage I and stage II) were included in this study. Each patient underwent conventional bronchoscopy with endobronchial biopsy (EBB) followed by the EBUS and puncturing at least two different lymph node stations. RESULTS Positive cytopathological verification of sarcoidosis in our study was obtained in 123 patients (92.5%). EBUS-TBNA was diagnostic in 116 patients (87.2%). EBB was positive in 26 patients (19.55%). Combination of EBUS-TBNA and EBB statistically increased diagnostic yield of sarcoidosis to 92.5%. Sensitivity of EBUS-TBNA with EBB was 93.9%, specificity 100%, PPV 100% and NPV 20%. CONCLUSIONS Combining EBUS-TBNA from at least two lymph node stations and EBB increased diagnostic yield of sarcoidosis. Such diagnostic strategy had almost 93% of diagnostic yield in stage I and stage II of sarcoidosis. Taking into account the safety of the whole procedure with endobronchial ultrasonography combined with conventional endoscopy with EBB and its cost effectiveness, TBLB can be intended to diagnose stage III or IV of pulmonary sarcoidosis.

Abstract
The field of interventional pulmonology has grown rapidly since first being defined as a subspecialty of pulmonary and critical care medicine in 2001. The interventional pulmonologist has expertise in minimally invasive diagnostic and therapeutic procedures involving airways, lungs, and pleura. In this review, we describe recent advances in the field as well as up-and-coming developments, chiefly from the perspective of medical practice in the United States. Recent advances include standardization of formalized training, new tools for the diagnosis and potential treatment of peripheral lung nodules (including but not limited to robotic bronchoscopy), increasingly well-defined bronchoscopic approaches to management of obstructive lung diseases, and minimally invasive techniques for maximizing patient-centered outcomes for those with malignant pleural effusion.

Abstract
Background: The diagnosis of sarcoidosis is not standardized but is based on three major criteria: a compatible clinical presentation, finding nonnecrotizing granulomatous inflammation in one or more tissue samples, and the exclusion of alternative causes of granulomatous disease. There are no universally accepted measures to determine if each diagnostic criterion has been satisfied; therefore, the diagnosis of sarcoidosis is never fully secure. Methods: Systematic reviews and, when appropriate, meta-analyses were performed to summarize the best available evidence. The evidence was appraised using the Grading of Recommendations, Assessment, Development, and Evaluation approach and then discussed by a multidisciplinary panel. Recommendations for or against various diagnostic tests were formulated and graded after the expert panel weighed desirable and undesirable consequences, certainty of estimates, feasibility, and acceptability. Results: The clinical presentation, histopathology, and exclusion of alternative diagnoses were summarized. On the basis of the available evidence, the expert committee made 1 strong recommendation for baseline serum calcium testing, 13 conditional recommendations, and 1 best practice statement. All evidence was very low quality. Conclusions: The panel used systematic reviews of the evidence to inform clinical recommendations in favor of or against various diagnostic tests in patients with suspected or known sarcoidosis. The evidence and recommendations should be revisited as new evidence becomes available.

Diagn Pathol 2020; 15:36. [PMID: 32293480 PMCID: PMC7158000 DOI: 10.1186/s13000-020-00958-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2020] [Accepted: 04/08/2020] [Indexed: 12/25/2022] Open
Abstract
Background Transbronchial needle aspiration (TBNA) is a minimally invasive procedure performed to diagnose lymph node (LN) adenopathy. TBNA with and without endobronchial ultrasound (EBUS) guidance has a high diagnostic yield for malignant LN enlargement, but the value for diagnosing benign LN enlargement has been less thoroughly investigated. Methods We retrospectively evaluated 3540 patients with mediastinal LN enlargement who received TBNA. One hundred sixty-six patients with benign mediastinal lymphadenopathy were included and 293 LNs were biopsied. A positive result was defined as a specific histological abnormality. Conventional TBNA (cTBNA) and EBUS-TBNA, as well as cTBNA and transbronchial forceps biopsy (TBFB), were compared. The subgroup analysis was stratified by disease type and LN size. Results A diagnosis was made in 76.84% of the EBUS-TBNA and 61.31% of the cTBNA (P < 0.05). EBUS-TBNA was superior to cTBNA for both granulomatous (65.18% vs. 45.45%, P < 0.05) and non-granulomatous disease (96.92% vs. 84.06%, P < 0.05). In contrast, the diagnostic yield of EBUS-TBNA was higher than that of cTBNA for LNs < 20 mm (79.44% vs. 64.29%, P < 0.05), but for LNs > 20 mm the difference was marginal. These findings were confirmed in a group of independent patients who received cTBNA plus EBUS-TBNA. The diagnostic yield did not differ between cTBNA and TBFB, but significantly increased to 76.67% when both modalities were employed. Conclusions EBUS-TBNA is the preferred minimally invasive diagnostic method for benign mediastinal LN disease. Combined cTBNA and TBFB is a safe and feasible alternative when EBUS is unavailable.

Abstract
Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a widely available diagnostic tool for suspected stage I/II sarcoidosis. Combination of EBUS-TBNA and transbronchial lung biopsy (TBLB) has been proposed as diagnostic procedure in clinical settings. Objectives: The aim of this study was to assess the diagnostic yield of combined EBUS-TBNA and TBLB and identify the markers correlated with a high diagnostic rate. Methods: We retrospectively analyzed the data of 37 patients with suspected stage I/II sarcoidosis with enlarged hilar or mediastinal lymph nodes on computed tomography (CT) images. These patients had been scheduled to undergo EBUS-TBNA and TBLB. Serum levels of sarcoidosis markers (angiotensin-converting enzyme [ACE], soluble interleukin-2 receptor [sIL-2R], and lysozyme), CT findings, and examination techniques were evaluated as predictive markers for diagnosis. Results: Of the 37 patients, 32 had undergone both EBUS-TBNA and TBLB, while the remaining 5 patients had only undergone EBUS-TBNA. The diagnosis was confirmed by TBLB in 16 of the 32 patients (50.0%), EBUS-TBNA in 31 of the 37 patients (83.8%), and combined TBLB and EBUS-TBNA in all patients (100.0%). The serum level of sIL-2R, but not that of ACE or lysozyme, was correlated with successful diagnosis by EBUS-TBNA. Conclusion: In patients with stage I/II sarcoidosis, the serum level of sIL-2R is a promising and useful marker for predicting the diagnosis by EBUS-TBNA and reducing the burden of additional TBLB and its possible complications.

Abstract
Background Drug resistance in tuberculosis (TB) is a major public health problem. It is easy to assess for drug resistance in pulmonary samples, but the resistance pattern of TB in the mediastinal nodes has not been studied. The aim of this study is to assess the incidence of multidrug resistance in tubercular mediastinal adenopathy with the help of endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration. Materials and Methods This was a prospective study at a tertiary care teaching hospital in New Delhi where 102 patients with positive mycobacterial cultures from mediastinal lymph node aspirates taken with the help of EBUS were enrolled over 24 months and their drug sensitivity to the first-line antitubercular drugs analyzed. Results There were 30 cases of drug resistance of 102 culture-positive cases. Of them, 8 patients had multidrug resistant TB (MDR-TB), 16 cases had only single drug resistance, and the remaining 6 cases had more than one drug resistance pattern but not MDR. In our study, the overall incidence of MDR-TB is 7.8% (8/102), although the incidence of MDR-TB in new and re-treatment cases is 2.2% (2/89) and 46.1% (6/13), respectively. Conclusion Such a high percentage of drug-resistant patients is common in tertiary care hospitals; however, similar percentages may be found in other settings as well. Therefore, all efforts should be made to take samples for Mycobacterium tuberculosis culture from the involved nodes before commencing therapy to avoid treatment failures.

Endobronchial ultrasound-guided mediastinal lymph node forceps biopsy in patients with negative rapid-on-site-evaluation: A new step in the diagnostic algorithm. CLINICAL RESPIRATORY JOURNAL 2019; 14:314-319. [PMID: 31845474 DOI: 10.1111/crj.13133] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2018] [Revised: 10/07/2019] [Accepted: 12/09/2019] [Indexed: 01/24/2023]
Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) provides a high diagnostic yield in lung cancer, but the yield for benign conditions and lymphoma is lower. The material obtained by EBUS-TBNA is limited by the lack of histopathological samples in some cases. The current 'expanded' aims of mediastinal lymph node (MLN) sampling are both an accurate diagnosis and adequate material for 'targeted' processing in malignant and benign disease. The sample obtained with the 21/22G EBUS needle may not be sufficient in all situations. OBJECTIVES The aim of the study was to evaluate the role of a novel technique for EBUS-guided MLN forceps biopsy (EBUS-TBFB) when EBUS-TBNA with rapid on-site-evaluation (ROSE) failed to provide a diagnosis. In addition, the technical aspects and safety of EBUS-TBFB were studied. METHODS About 30 consecutive patients with enlarged MLN, with a negative EBUS-TBNA ROSE were included. EBUS-TBFB was done by the method described below. The histopathology and complications were recorded. RESULTS Adequate samples for analysis were obtained in all the patients with both EBUS-TBNA and EBUS-TBFB. In patients with a non-diagnostic EBUS-ROSE, EBUS-TBFB led to positive diagnostic results in an additional 8/30 patients (27%). Mild bleeding was noted in two patients who underwent EBUS-TBFB, which resolved with conservative management. The procedure was safe with no major complications. CONCLUSION In patients with a negative EBUS-ROSE, EBUS-TBFB using this technique is safe and augments the diagnostic yield. EBUS-TBFB adds to the armamentarium of EBUS, especially in benign aetiologies of MLN enlargement.

Abstract
Introduction Transbronchial lung cryobiopsy (TBLC) is an endoscopic technique proven to be useful in diagnostic approach to interstitial lung disease (ILD), but its role in sarcoidosis is not fully established. The aim of the present study was to assess the diagnostic yield of TBLC in sarcoidosis and its safety profile. Methods Retrospective analysis of patients, evaluated in a tertiary hospital ILD outpatient clinic, who underwent TBLC in the diagnostic work-up. TBLC was performed in accordance with the 2018 expert statement from the Cryobiopsy Working Group. Results 32 patients were included (mean±sd age 47.7±12.6 years, 59.4% male) and divided into three groups: highly likely sarcoidosis (n=21), possible sarcoidosis (n=6) and unlikely sarcoidosis (n=5). A mean of 2.8±0.8 TBLCs were performed. The definitive diagnosis was established by TBLC in 20 out of 27 patients with suspected sarcoidosis. Two patients were diagnosed with sarcoidosis by other methods performed afterwards. TBLC leaded to other diagnosis as well, such as fungal infection (n=1), hypersensitivity pneumonitis (n=1) and silicosis (n=3), making the diagnostic yield for suspected sarcoidosis of TBLC of 92.6%. TBLC was also able to show compatible histological features in five patients whom sarcoidosis was not previously considered. The complications reported overall were pneumothorax in five (15.6%) patients and moderate bleeding in one (3.1%) case. Conclusion In this cohort, TBLC was a safe, reliable and useful procedure in sarcoidosis diagnosis. These results suggest that TBLC can be used successfully in those cases where a definitive diagnosis could not be reached with the usual and less-invasive diagnostic tools. TBLC is a safe procedure with a high diagnostic yield in patients with a prior suspicion of sarcoidosis. Moreover, it can diagnose atypical cases in which previous methods are inconclusive.http://bit.ly/2KWJxLG

Abstract
Endobronchial ultrasound (EBUS) and transbronchial needle aspiration (TBNA) have changed the landscape of pulmonology. Mediastinal structures beyond the confines of airway walls are visualized in real-time with EBUS, leading to improved accuracy of tissue sampling and diagnostic yield. With the development of various needle sizes ranging from 25-G to 19-G, the sampling of lymph nodes is becoming easier and more commonplace. Yet, certain conditions such as sarcoidosis and lymphoma may still be difficult to diagnose via EBUS-TBNA. Furthermore, in the age of targeted therapy, there are more demands on EBUS-TBNA samples for molecular marker testing and next-generation sequencing. Here, we present a complementary methodology, EBUS-guided intranodal forceps biopsy (EBUS-IFB), for tissue acquisition that may help address these deficiencies. Specifically, we aim to propose indications, contraindications, outline approaches in performing IFB, and provide an overview of the data for this complementary technique.

Abstract
BACKGROUND Histological diagnosis of systemic granulomatosis may be difficult. The question of the best histological target remains unanswered. CASE We report here the observation of a patient admitted in intensive care unit for severe hypercalcemia in the context of polylymphadenopathy and constitutional symptoms. Assessment of this hypercalcemia was suggestive of systemic granulomatosis. The CT (computed tomodensitometry) revealed lymphadenopathies of the mediastinum and the hepatic hilus, hepatomegaly and heterogeneous splenomegaly. At this stage, our main hypotheses were: lymphoid hematopathy, sarcoidosis, tuberculosis. An echo-guided biopsy of the spleen allowed the histological diagnosis of systemic granulomatosis suggestive of sarcoidosis, without significant complication in the course. CONCLUSION This observation illustrates the efficiency and safety of spleen biopsy for the histological diagnosis of systemic granulomatosis.

Abstract
Here we present a comprehensive review of the literature concerning the utility of convex probe endobronchial ultrasound (CP-EBUS) in the diagnosis and treatment of nonmalignant conditions and discuss the associated complications. CP-EBUS has been conventionally used for the staging of lung cancer and sampling of mediastinal and hilar nodes. However, its application is not limited to malignant conditions, and it is gaining acceptance as a diagnostic modality of choice for nonmalignant conditions such as tuberculosis, sarcoidosis, pulmonary embolism, thyroid lesions, and cysts. Moreover, its therapeutic value allows for extended applications such as mediastinal and thyroid cyst drainage, fiducial marker placement for radiation therapy, and transbronchial needle injection. The noninvasiveness, low complication rate, high diagnostic yield, and satisfactory sensitivity and specificity values are the main attributes that lend credence to the use of CP-EBUS as a standalone primary diagnostic and therapeutic tool in pulmonary medicine in the foreseeable future.

Abstract
OBJECTIVES In patients with testicular Germ Cell Tumors (GCT) noncaseating granulomatous diseases such as Sarcoid Like Lesions (SLL) or Sarcoidosis can mimic metastasis due to hilar or mediastinal lymphadenopathy. Due to the clinical and prognostic impact, exclusion of malignant diseases is mandatory. MATERIAL AND METHODS Retrospectively, data from 636 GCT patients, who were seen in the course of tumor surveillance/follow-up were collected. Focus was put on the detection of tumor relapse vs. noncaseating granulomatous reactions. For the differential diagnosis of thoracic lymphadenopathy or pulmonary infiltrates either bronchoscopy (e.g., endobronchial ultrasound-guided transbronchial needle aspiration, endobronchial ultrasound-guided transbronchial needle aspiration) or thoracic surgery was performed. Both GCT patients with either tumor relapse or coexisting SLL were compared to GCT patients without SLL and tumor relapse. RESULTS Twenty-nine patients suffered from suspected tumor relapse. Whereas thoracic relapses were suspected in 15 patients on chest computed tomography, thoracic relapse was confirmed in 5 cases by open surgery. In 2 cases open surgery yielded reactive lymphadenitis, and in 8 cases SLL was diagnosed either via EBUS-TBNA (n = 7) or thoracoscopic wedge resection plus lymphadenectomy (n = 1). With focus on overall survival, no relevant difference was found between all tested subgroups (P = 0.265; logrank test). CONCLUSIONS In GCT patients, the coexistence of noncaseating granulomatous disease is common. Minimal invasive bronchoscopic techniques can serve for the cytopathologic exclusion of malignant thoracic manifestations. In our monocenter patient group the coexistence of SLL did not have any prognostic impact on overall survival.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the commonly used technique for pathological confirmation of clinically suspected sarcoidosis, mostly owing to its consistently high success rate in the detection of granulomas. However, other possible advantages, which are less appreciated and often poorly studied, may also contribute to the wider use of EBUS-TBNA in the future. These advantages include refinement of differential diagnoses through the study of lymph node characteristics during B-mode examination; reduction of complications associated with bronchoscopy, as well as improved triage of the specimen for ancillary studies with the use of rapid on-site evaluation; optimization of the quality of the sample through the selection of a target area for biopsy with minimal vascularity and absence of calcifications by using the colour Doppler and the B-mode; and prediction of the presence of extensive lymph node fibrosis by using the strain elastography module. Yet, limitations and possible clinical drawbacks should also be acknowledged. Indeed, due to the lack of specificity of the pathology findings in EBUS-derived samples, the diagnosis of sarcoidosis is one of the exclusion and should remain essentially clinical. The external validity of EBUS-TBNA results in sarcoidosis is questionable, as they mainly derive from studies in populations with a high disease prevalence. Finally, the risk exists that the low morbidity and high diagnostic yield of EBUS-TBNA may lead to its overuse in patients with clinical/radiological findings specific enough to secure a clinical diagnosis of sarcoidosis.

Abstract
Background Isolated mediastinal lymphadenopathy is an increasingly common finding as a result of the increasing use of cross-sectional thoracic imaging. We investigated the performance of endobronchial ultrasoundguided transbronchial needle-aspiration (EBUS-TBNA) in establishing a pathological diagnosis in patients with isolated mediastinal lymphadenopathy. Methods We retrospectively analysed all consecutive EBUS-TBNA examinations performed over a 4-year period at a single tertiary referral centre. Final diagnoses were made using pathology reports, correlated with clinical features and the results of any other investigations. Results In total, 126 EBUS-TBNA examinations were performed to investigate isolated mediastinal lymphadenopathy. A positive pathological diagnosis was made following EBUSTBNA in 54 cases (43%). When the results of further investigations and variable radiological follow up were included, the final sensitivity of EBUS-TBNA for making a diagnosis in isolated mediastinal lymphadenopathy was 80% (95% CI 69%-89%). Conclusions This study confirms that EBUS-TBNA has acceptable sensitivity for detecting both benign and malignant pathologies underlying isolated mediastinal lymphadenopathy.

Abstract
Background and Objective EBUS-TBNA has revolutionized the diagnostic approach to thoracic diseases from a surgical to minimally invasive procedure. In non small-cell lung cancer (NCSLC) patients, EBUS-TBNA is able to dictate the consecutive therapy both for early and advanced stages, providing pathological diagnosis, mediastinal staging, and even adequate specimens for molecular analysis. This study reports on the ability of EBUS-TBNA to make different diagnoses and dictates the consecutive therapy in a large cohort of patients presenting different thoracic diseases. Methods All procedures performed from January 2012 to September 2016 were reviewed. Five groups of patients were created according to the main indications for the procedure. Group 1: lung cancer staging; Group 2: pathological diagnosis in advanced stage lung cancer; Group 3: lymphadenopathy in previous malignancies; Group 4: pulmonary lesions; Group 5: unknown origin lymphadenopathy. In each group, the diagnostic yield of the procedure was analysed. Non malignant diagnosis at EBUS-TBNA was confirmed by a surgical procedure or clinical and radiological follow-up. Results 1891 patients were included in the analysis. Sensitivity, negative predictive value, and diagnostic accuracy in each group were 90.7%, 79.4%, and 93.1% in Group 1; 98.5%, 50%, and 98.5% in Group 2; 92.4%, 85.1%, and 94.7% in Group 3; 90.9%, 51.0%, and 91.7% in Group 4; and 25%, 83.3%, and 84.2% in Group 5. Overall sensitivity, negative predictive value, and accuracy were 91.7%, 78.5%, and 93.6%, respectively. Conclusions EBUS-TBNA is the best approach for invasive mediastinal investigation, confirming its strategic role and high accuracy in thoracic oncology.

Abstract
BACKGROUND While endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is widely used as an initial diagnostic procedure for pathological confirmation of sarcoidosis, it is unclear how many passes are required to obtain diagnostic materials. OBJECTIVES The aim of this study was to determine the number of needle passes needed for the diagnosis of stage I/II sarcoidosis using EBUS-TBNA. METHODS At three institutions, 109 patients with suspected stage I/II sarcoidosis were recruited and underwent 6 passes of EBUS-TBNA for the main target lesion. Additional EBUS-TBNA for other lesions was permitted. The cumulative yields of needle passes for detecting noncaseating epithelioid cell granulomas were analyzed. RESULTS A total of 109 patients underwent EBUS-TBNA for 184 lesions. EBUS-TBNA identified specimens containing granulomas in 81 of 92 patients (88%) with a final diagnosis of sarcoidosis. The cumulative yields through the first, second, third, fourth, fifth, and sixth passes for the main target lesion were 63, 75, 82, 85, 86 and 88%, respectively. In the 55 patients that underwent EBUS-TBNA for multiple lesions, the cumulative yields of 2 passes per lesion for 2 lesions (total of 4 passes) and of 4 passes for single lesions were 86 and 84%, respectively (p = 1.00). CONCLUSIONS If rapid on-site cytological evaluation is not available, we recommend at least 4 passes per patient for either single or multiple lesions with EBUS-TBNA for pathological diagnosis of stage I/II sarcoidosis.

Abstract
PURPOSE Transbronchial lung cryobiopsy (TBLC) is a novel technique that has proved to be useful in diagnosing various interstitial lung diseases (ILD). The use of TBLC to diagnose sarcoidosis in an unselected patient population is unknown, and could be complimentary to endobronchial ultrasound fine needle aspiration (EBUS-FNA). METHODS A retrospective analysis of 36 patients in a single, tertiary-care, academic medical center was conducted to describe the yield of both EBUS-FNA and TBLC in the diagnosis of suspected sarcoidosis over a three year period. A grading system to evaluate the presence and extent of specific radiographic features on computed tomography chest imaging studies was compared to the results of EBUS-FNA and TBLC. Complications associated with the procedures were also noted. RESULTS The overall diagnostic yield in our cohort (all pathologic diagnosis considered) was 80.6% (29 out of 36 patients had a definite pathologic diagnosis). Eighteen patients referred for possible sarcoidosis had a positive bronchoscopic specimen confirming the diagnosis of sarcoidosis. For those patients with a pathologic diagnosis of sarcoidosis, the diagnostic yield for EBUS-FNA and TBLC was 66.7% each (12 out of 18 patients), while the combined diagnostic yield for EBUS-FNA and TBLC increased to 100%. For all cases, the pneumothorax rate was 11.1%. CONCLUSIONS TBLC appears to be a safe and complimentary technique to diagnose sarcoidosis and could be considered part of the diagnostic armamentarium in bronchoscopic centers.

Abstract
BACKGROUND Mediastinoscopy is a good method to evaluate mediastinal lesions. We sought to determine the current role of mediastinoscopy in the investigation of non-lung cancer patients with mediastinal lymphadenopathy. MATERIALS AND METHODS We retrospectively reviewed clinical parameters (age, gender, histological diagnosis, morbidity, mortality) of all patients without lung cancer who consecutively underwent mediastinoscopy in Hospital of Faculty of Medicine of Dicle University between June 2003 and December 2016. RESULTS Two-hundred twenty nine patients without lung cancer who underwent mediastinoscopy for the pathological evaluation of mediastinum during the study period were included. There were 156 female (68%) and 73 male (32%) patients. Mean age was 52.6 years (range, 16 to 85 years). Mean operative time was 41 minutes (range, 25 to 90 minutes). Mean number of biopsies was 9.3 (range, 5 to 24). Totally, 45 patients (19.6%) had previously undergone a nondiagnostic bronchoscopic biopsy such as transbronchial needle aspiration or endobronchial ultrasound-guided transbronchial needle aspiration. Mediastinoscopy was diagnostic for all patients. Diagnosis included sarcoidosis (n=100), tuberculous lymphadenitis (n=66), anthracosis lymphadenitis (n=44), lymphoma (n=11) metastatic carcinoma (n=5), and Castleman's disease (n=1); there was a diagnosis of silicosis in one patient and tymoma in one patient. Neither operative mortality nor major complication developed. The only minor complication was wound infection which was detected in three patients. CONCLUSION Although newer diagnostic modalities are being increasingly used to diagnose mediastinal diseases, mediastinoscopy continues to be a reliable method for the investigation of mediastinal lesions.

Abstract
BACKGROUND Intrathoracic tuberculous (TB) lymphadenitis is a diagnostic challenge to the clinician. Although endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can obtain a sample from the affected lymph node, the diagnosis of TB lymphadenitis by cytopathology remains inaccurate. OBJECTIVE To evaluate the efficacy of EBUS-TBNA rinse fluid TB polymerase chain reaction (PCR) assay for the diagnosis of intrathoracic TB lymphadenitis. METHODS A retrospective study was conducted on 102 patients who underwent EBUS-TBNA for diagnostic evaluation of intrathoracic lymphadenopathy. EBUS-TBNA specimens were evaluated by cytopathological examination. Rinse fluid of the needle was routinely submitted for acid-fast bacillus (AFB) staining, mycobacterial culture, and TB-PCR using the AnyplexTM MTB/NTM real-time detection kit. RESULTS Of 102 patients, 16 were diagnosed with intrathoracic TB lymphadenitis by either microbiology, cytopathology, or on clinical grounds. The sensitivity, specificity, positive predictive value, and negative predictive value of rinse fluid TB PCR assay were 56.2%, 100.0%, 100.0%, and 92.5%, respectively. Using the area under the ROC curve (AUC) as a measure of a diagnostic performance, TB-PCR had the highest AUC, compared with mycobacterial culture, AFB smear, and finding of necrotizing granulomatous inflammation (0.78, 0.75, 0.56, and 0.72, respectively). A combination of TB PCR, mycobacterial culture, and finding of necrotizing granulomatous inflammation provided the best diagnostic performance (sensitivity, specificity, positive predictive value, negative predictive value, and AUC of 75.0%, 100.0%, 100.0%, 95.6%, and 0.88, respectively). CONCLUSIONS EBUS-TBNA rinse fluid TB-PCR is useful in the diagnosis of intrathoracic TB lymphadenitis. Combining TB-PCR with mycobacterial culture and cytopathological findings improved the diagnosis performance.

Abstract
Currently, whether endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is superior to conventional TBNA (cTBNA) in the diagnosis of mediastinal lymphadenopathy remains controversial. We undertook a meta-analysis of randomized controlled trials (RCTs) to evaluate the diagnostic yield of EBUS-TBNA versus cTBNA in the diagnosis of mediastinal lymphadenopathy, both in benign and malignant etiologies. Computer-based retrieval was performed on PubMed and EMBASE. The quality was evaluated according to the quality assessment of diagnostic accuracy studies-2, and Meta-Disc was adopted to perform meta-analysis. The pooled sensitivity, specificity, and diagnostic odds ratio (DOR) with 95 % confidence intervals (CIs) were calculated. The summary receiving operating characteristic curve as well as the areas under curve (AUC) was measured. Four studies with a total of 440 patients met the inclusion criteria. Our results showed that the pooled sensitivity was 0.90 (95 % CI 0.85-0.94) and 0.76 (95 % CI 0.68-0.82), pooled specificity was 0.75 (95 % CI 0.60-0.87) and 0.94 (95 % CI 0.86-0.98), DOR was 75.38 (95 % CI 16.38-346.97) and 108.17 (95 % CI 13.84-845.35), and AUC was 0.9339 and 0.9732 for EBUS-TBNA group and cTBNA group, respectively. Although EBUS-TBNA with a higher sensitivity performs better than cTBNA, there is lack of enough evidence regarding EBUS-TBNA being superior to cTBNA in the diagnosis of mediastinal lymphadenopathy. Considering the limitations of methodology and limited data, further robust RCTs are needed to verify the current findings and investigate the optimal choice in patients receiving TBNA.

Abstract
Background: Effective use of the convex curvilinear ultrasound bronchoscope in the esophagus (EUS-B) for fine needle aspiration biopsy of mediastinal structures is now well described. In contrast, there is little to no reporting, depending on the site of EUS-B for access to sub-diaphragmatic structures. Our practice has been accessing sub-diaphragmatic sites for years. This review documents our experience with EUS-B to biopsy liver, left adrenal glands, and coeliac lymph nodes. Methods: After Institutional Review Board's approval, all endosonographic procedures performed by interventional pulmonary between July 2013 and June 2015 were reviewed. Those including biopsy of sub-diaphragmatic sites were then selected for analysis. Results: Over the study interval, 45 sub-diaphragmatic biopsy procedures (25 left adrenal glands, 7 liver, and 13 celiac node) were performed with EUS-B. In all cases, cellular adequacy was present, and samples were large enough for immunohistochemistry and any relevant ancillary studies. Metastatic malignancy was documented in 58% of cases, 16% of cases contained benign diagnostic findings, and in 27% of cases, normal organ tissue was documented. There were no complications. Conclusions: Operators comfortable with the endobronchial ultrasound scope in both the airway and the esophagus can actively seek and successfully perform biopsy of sub-diaphragmatic abnormalities when present and can thereby add to the diagnostic value of the procedure.

Abstract
Background Studies have reported a high diagnostic yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the diagnosis of sarcoidosis. We sought to review the yield of EBUS-TBNA for the diagnosis of sarcoidosis at our institution over time, and examine factors that may influence this yield. Methods Patients who underwent EBUS-TBNA for suspected sarcoidosis between December 2008 and November 2011 were identified. EBUS was performed without rapid on-site evaluation (ROSE) of samples. The final diagnosis was based on the results of all invasive diagnostic procedures and/or clinical follow-up. Logistic regression analysis was used to examine the effect of various factors on yield. Results 43 patients underwent 45 EBUS-TBNA procedures for suspected sarcoidosis. A total of 115 lymph nodes were sampled. The 21 G needle was used in 51% of procedures. The mean number of lymph node stations sampled was 2.6 (SD 0.7) and the mean number of needle passes per procedure was 7.8 (SD 2.0). Non-necrotising granulomatous inflammation was detected in EBUS-TBNA samples from 34/45 (76%) procedures. The overall diagnostic yield increased to 36/45 (80%) following a cytopathology review for this study. Needle gauge, number of lymph node stations sampled and number of needle passes were not associated with diagnostic yield. The yield of EBUS-TBNA increased significantly after the first 15 procedures performed for suspected sarcoidosis; the 2 additional cases diagnosed after the cytopathology review were part of this early experience. Conclusions EBUS-TBNA is a valuable technique for the diagnosis of sarcoidosis when performed without ROSE. The yield of the procedure improved significantly over time, based on operator and cytopathologist experience.

Abstract
Sarcoidosis is a systemic disease, with lung involvement in almost all cases. Abnormal chest radiography is usually a key step for considering diagnosis. Lung impact is investigated through imaging; pulmonary function; and, when required, 6-minute walk test, cardiopulmonary exercise testing, or right heart catheterization. There is usually a reduction of lung volumes, and forced vital capacity is the most accurate parameter to reflect the impact of pulmonary sarcoidosis with or without pulmonary infiltration at imaging. Various evolution patterns have been described. Increased risk of death is associated with advanced pulmonary fibrosis or cor pulmonale, particularly in African American patients.

Abstract
The diagnosis of sarcoidosis, a systemic granulomatous disease, is based on a compatible clinical-radiological picture and the histological evidence of noncaseating granulomas. Other diseases mimicking sarcoidosis, mostly infections and other granulomatoses, have to be excluded. There is no single test for sarcoidosis, and the presence of granulomas alone does not establish the diagnosis. Symptoms of sarcoidosis are not specific and can be markedly different according to organ involvement and disease course. Respiratory symptoms and fatigue are the most common symptoms at any stage of disease. Histological confirmation is not needed for Löfgren's or Heerfordt's syndrome and asymptomatic bihilar lymphadenopathy. The radiological staging system is still based on chest radiography, and computed tomography is not mandatory for routine follow-up. (18)F-fluorodeoxyglucose positron emission tomography may be of value in special cases. For assessment of lung involvement and follow-up, pulmonary function tests are necessary with vital capacity being the most important single parameter and diffusion capacity the most sensitive. Bronchoscopy with biopsy is the most common procedure for detection of granulomas, when there is no easier biopsy site like skin or peripheral lymph nodes. Endobronchial ultrasonography-guided transbronchial needle aspiration has replaced mediastinoscopy for evaluation of mediastinal and hilar lymph nodes with a high diagnostic yield. Despite numerous studies, no single biomarker can be reliably used for correct diagnosis or exclusion of sarcoidosis. Genetic testing, despite promising advances, has still not been included in routine care for sarcoidosis patients. The long-term prognosis of sarcoidosis depends on the different organ manifestations: Cardiac or central nervous involvement, together with respiratory complications, is critical. A multidisciplinary approach is necessary for comprehensive care of the sarcoidosis patient.

Abstract
Endobronchial ultrasound has become the first choice standard of care procedure to diagnose benign or malignant lesions involving mediastinum and lung parenchyma adjacent to the airways owing to its characteristics of being real-time and minimally invasive. Although the incidence of lung cancer has been decreasing, it is and will be the leading cause of cancer-related mortality in the next few decades. When compared to other cancers, lung cancer kills more females than breast and colon cancers combined and more males than colon and prostate cancers combined. The type of lung cancer has changed in recent decades and adenocarcinoma has become the most frequent cell type. Prognosis of lung cancer depends upon the cell type and the staging at the time of diagnosis. The cell type and molecular characteristics of adenocarcinoma may allow individualized targeted treatment. Other malignant conditions in the mediastinum and lung (eg, metastatic lung cancers and lymphoma) can be biopsied using endobronchial ultrasound needles. Endobronchial ultrasound needle biopsies provides mostly cytology specimens due to its small sizes of needles (22 gauge or larger) which may not give enough tissue to make a definitive diagnosis in malignant (eg, lymphoma) or benign conditions (eg, sarcoidosis). EchoTip ProCore endobronchial needle released in early 2014 provides histologic biopsy material. Larger tissue biopsies may potentially provide a higher diagnostic yield and it eliminates mediastinoscopy or other surgical interventions. Here we aim to review bronchoscopic approach in the diagnosis of mediastinal lesions with emphasis of EchoTip ProCore needles.

Abstract
RATIONALE Multidetector-row chest computed tomography scan is a common initial imaging modality and endobronchial ultrasound is a minimally invasive diagnostic tool used to evaluate enlarged lymph nodes, but comparisons of imaging results are lacking. OBJECTIVES To determine the size of thoracic lymph nodes and the strength of agreement between each measurement from coronal plane computed tomography and static endobronchial ultrasound images. METHODS A retrospective review of consecutive patients who underwent endobronchial ultrasound-transbronchial needle aspiration of their lymph nodes because of clinical suspicion of benign or malignant thoracic disease. MEASUREMENTS AND MAIN RESULTS One hundred and twenty-four lymph nodes from the mediastinal (74.2%) and hilar (25.8%) stations were measured in 59 patients (mean age, 64.5 yr; 33 males). The mean (standard deviation) short-axis diameter on computed tomography was 14.1 (6.7) mm compared with 12.6 (6.6) mm on endobronchial ultrasound. Benign lymph nodes (n = 42) were larger on computed tomography than on endobronchial ultrasound (14.1 [6.2] vs. 11.5 [6.2] mm). Malignant lymph nodes (n = 35) were larger on endobronchial ultrasound than on computed tomography (17.3 [6.4] vs. 16.2 [6.7] mm). Sixty-five percent of the lymph nodes that were initially interpreted as not enlarged on axial computed tomography images measured greater than 10 mm on each imaging modality (12.5 [5.9] mm on computed tomography and 10.5 [5.6] mm on endobronchial ultrasound) and 24% of the sampled lymph nodes from this group contained malignant cells. Random-effects maximal likelihood linear regression showed a statistically significant difference between endobronchial ultrasound and the computed tomography method for measuring short-axis diameter in all 124 lymph nodes. There was a weak agreement (intraclass correlation, rho: 0.44 [95% confidence interval, 0.31-0.59]) between short-axis diameter measurements from each imaging modality. CONCLUSIONS Our single-center study shows that there was poor correlation between computed tomography and endobronchial ultrasound for the measurement of mediastinal and hilar lymph nodes. Malignant cells were recovered by ultrasound-guided needle aspiration from a substantial fraction of lymph nodes that were initially interpreted as normal in size. If these findings are confirmed, new criteria may be needed for lymph node measurement on computed tomography that will guide selection of lymph nodes for endobronchial ultrasound-transbronchial needle aspiration.

Abstract
Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) had an enormous impact on the current advancement in diagnostic bronchoscopy. The aims of the present study were: (1) to evaluate the added value of EBUS-TBNA to routine diagnostic bronchoscopy performed in patients with mediastinal lymph node enlargement and (2) to identify factors that affect the diagnostic yield of EBUS-TBNA. We retrospectively analyzed 712 EBUS-TBNA procedures out of the 4081 bronchoscopies performed in the years 2009-2014. The number of EBUS-TBNA procedures increased from 61 (8.8 % of all bronchoscopies) in 2009 to 160 (21.4 %) in 2014. In 625 (87.8 %) patients adequate cytological material was obtained. Based on cytological examination of EBUS-TBNA aspirates, specific diagnosis was made in 367 (51.5 %) patients. The forceps biopsy of endobronchial lesions provided specific diagnosis in only 204 (28.6 %) patients. The percentage of patients with EBUS-TBNA based diagnosis increased steadily from 34.4 % in 2009 to 65.0 % in 2014 (p < 0.0001). The median lymph node diameter in patients with positive EBUS-TBNA findings was 20 (IQR 15-30) mm and was significantly larger than that in patients with negative EBUS-TBNA results (15 (IQR 10-20) mm, p = 0.0001). The highest diagnostic yield (78.5 %) was found in patients with lymph node dimension between 31 mm and 40 mm. We conclude that EBUS-TBNA is a valuable diagnostic method in an unselected group of patients with mediastinal lymph node enlargement. The percentage of positive EBUS-TBNA diagnoses is related to lymph node dimensions. The overall efficacy of EBUS-TBNA improves with increasing years of experience.

The Use of Endobronchial Ultrasound in the Diagnosis of Subacute Pulmonary Histoplasmosis. DIAGNOSTIC AND THERAPEUTIC ENDOSCOPY 2015; 2015:510863. [PMID: 26543344 PMCID: PMC4620272 DOI: 10.1155/2015/510863] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/23/2015] [Accepted: 08/30/2015] [Indexed: 11/17/2022]
Abstract
Objective. Endobronchial ultrasound (EBUS) utility in diagnosis in malignant and granulomatous mediastinal disease has been well demonstrated. We propose to examine the role of EBUS transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of subacute pulmonary histoplasmosis (SPH) with mediastinal lymphadenopathy in an area where histoplasmosis is endemic. Methods. A retrospective review was performed in a single academic institution between 2009 and 2012 of patients referred for EBUS-TBNA who had radiographic imaging and clinical symptomatology suspicious for SPH. Seven patients were reviewed. TBNA results showing granulomatous disease with areas of necrosis in the appropriate clinical setting were considered to be adequate for the diagnosis of SPH when alternative diagnosis was excluded. Patients underwent further clinical follow-up of 12 months to determine the final diagnosis. Results. All seven patients were felt to have SPH diagnosis reached by a combination of clinical presentation, EBUS-TBNA results, fungal serologies, and antigen testing. None of the patients needed further invasive procedures. Conclusions. EBUS-TBNA is a minimally invasive tool that can be used to support a diagnosis of SPH in patients with a high degree of clinical suspicion. EBUS-TBNA should be considered as an adjunctive diagnostic procedure for patients with SPH in an appropriate clinical setting.

Abstract
Background: Endobronchial ultrasound-guided transbronchial fine-needle aspiration is a minimally invasive technique for diagnosis of mediastinal lesions. Although most studies have reported the utility of EBUS-FNA in malignancy, its use has been extended to the benign conditions as well. Objective: To evaluate the diagnostic yield and cytologic accuracy of endobronchial ultrasound-guided transbronchial fine-needle aspiration (EBUS-FNA) in cases of clinically and radiologically suspected granulomatous diseases. Patients and Method: From May 2010 to April 2015, 43 of 115 patients who underwent EBUS-FNA at one center for radiologically and clinically suspicious granulomatous lesions, and with no definite histological diagnosis, were included in this retrospective study. Results: When the histological diagnosis was taken as the gold standard, the sensitivity of EBUS-FNA was 85% and specificity was 100% with the positive predictive value of 100. The combined diagnostic sensitivity of EBUS-FNA and transbronchial lung biopsy was 100%. In 4 cases, cell block provided an exclusive morphological diagnosis of sarcoidosis which was noncontributory by EBUS-FNA. Conclusion: Our study supports the use of EBUS-FNA, by virtue of being a safe, minimally invasive, and an outpatient procedure, in the diagnosis of granulomatous mediastinal lymphadenopathy, thereby obviating more invasive testing in a significant number of patients. Also, cell block provides additional data in the diagnosis in these benign mediastinal diseases.

Abstract
OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is commonly used for clinical diagnosis of mediastinal lymphadenectasis. This study aimed to evaluate the diagnostic significance of EBUS-TBNA for mediastinal lymphadenectasis in a large single center. METHODS A total of 846 patients who were not definitively diagnosed with mediastinal lymphadenectasis underwent EBUS-TBNA were retrospectively analyzed in this study. RESULTS In total, 842 patients underwent EBUS-TBNA successfully. There were 589 patients with malignancy, including squamous carcinoma (118 cases; 20.6%), adenocarcinoma (187 cases; 32.7%) and small cell carcinoma (88 cases; 15.4%). A total of 253 patients were diagnosed with benign disease, including tuberculosis (111 cases; 43.9%) and sarcoidosis (93 cases; 36.7%). The diagnostic sensitivity of lung cancer, tuberculosis and sarcoidosis were 94.4%, 81.1% and 51.6%, respectively. The overall sensitivity of EBUS-TBNA was 92.0%. N2 stage in lung cancer patients who were diagnosed by EBUS-TBNA was significantly higher than other stages. The positive rate of targeted puncture is high for the lymph nodes whose short-axis diameters were larger than 1 cm. CONCLUSION The operation risk of EBUS-TBNA is relatively small. In diseases complicated by mediastinal lymphadenectasis, malignant diseases are most, and benign diseases mainly are granulomatous. EBUS-TBNA is a valuable diagnostic technique in patients with mediastinal lymphadenectasis whose diagnosis have not been determined.

Abstract
BACKGROUND AND AIMS Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an accurate and minimally invasive technique that has been shown to have excellent diagnostic yield in the diagnosis of mediastinal and hilar lymphadenopathy. However, endoscopic bronchial biopsy (EBB) and transbronchial lung biopsy (TBLB) are still the standard method for making a pathologic diagnosis of sarcoidosis. The aim of this study was to compare the diagnostic yield of EBUS-TBNA and TBLB through a flexible bronchoscope in patients with stage I and II sarcoidosis. METHODS A total of 653 patients with suspected stage I and II sarcoidosis were included in this retrospective study. After radiological assessment, patients were qualified to bronchoscopy. Patients underwent sequential EBUS-TBNA followed by TBLB and/or EBB. In all patients, 1056 biopsies from mediastinal lymph nodes group were taken. RESULTS In all of the biopsied lymph nodes, positive results were obtained in 549 patients (84%). In 180 patients with stage II TBLB, a biopsy was taken from affected part of the lung. Positive results were found in 79 patients (43.9%). EBB was performed in 340 patients, with a positive result in 101 (29.7%). Mediastinoscopy was performed in 60 patients (9.2%) with a negative result in EBUS-TBNA, TBLB and/or EBB. Non-caseating granulomas were found in 48 patients. The sensitivity of TBLB technique alone was significantly lower at 43.9% (79/180) (P < 0.001). The sensitivity of EBB was significantly lower than EBUS-TBNA and TBLB and reached 29.7% (101/340) (P < 0.0001, P < 0.003). The overall diagnostic accuracy for EBUS-TBNA was 84%, and the combination of EBUS-TBNA with standard bronchoscopic techniques had a diagnostic accuracy of 89%. CONCLUSION The diagnostic yield of the EBUS-TBNA for stage I and II sarcoidosis is clearly higher than for TBLB and EBB. The combination of EBUS-TBNA with standard bronchoscopic techniques is safe and feasible, and optimizes the diagnostic yield in patients with pulmonary sarcoidosis and enlarged intrathoracic lymph nodes. EBUS-TBNA in combination with standard bronchoscopy may be considered to be the first-line investigation in patients with suspected sarcoidosis and enlarged intrathoracic lymphadenopathy.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is superior to conventional transbronchial needle aspiration (cTBNA) in the staging of lung cancer. However, its efficiency in diagnosis of sarcoidosis when combined with endobronchial biopsy (EBB) and transbronchial lung biopsy (TBLB) has not been studied. This randomized controlled trial compares diagnostic yield of EBUS-TBNA vs cTBNA in combination with EBB and TBLB. METHODS Patients with clinical diagnosis of sarcoidosis were randomized 1:1 to EBUS-TBNA or cTBNA. All patients underwent TBLB and EBB. The primary outcome was detection of granulomas. The secondary end points were the individual and cumulative yields of various procedures, serious adverse events, and procedure time. RESULTS Of the 130 patients, sarcoidosis was diagnosed in 117 (62 cTBNA, 55 EBUS-TBNA). The two groups were similar at baseline. Granulomas were demonstrated in 104 (53 cTBNA, 51 EBUS-TBNA) patients and were similar in two groups (85.5% vs 92.7%, P = .34). Individually, EBUS-TBNA had the highest yield (41 of 55, 74.5%), which was better than cTBNA (30 of 62, 48.4%, P = .004) or EBB (40 of 111, 36.3%, P < .0001) but not TBLB (78 of 112, 69.6%, P = .54). Adding EBB/TBLB to cTBNA led to an increase in granuloma detection, whereas the addition of TBLB (but not EBB) significantly enhanced the yield of EBUS-TBNA. The procedure time was significantly longer with EBUS-TBNA. No major adverse events occurred. CONCLUSIONS Individually, EBUS-TBNA has the highest diagnostic yield in sarcoidosis, but it should be combined with TBLB for the optimal yield. The diagnostic yield of cTBNA (plus EBB and TBLB) is similar to EBUS-TBNA plus TBLB. TRIAL REGISTRY ClinicalTrials.gov; No.: NCT01908868; URL: www.clinicaltrials.gov.

Abstract
We herein report two cases of thymomas diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). In both cases, the tumor was adjacent to the central airway. Therefore, we attempted to perform EBUS-TBNA in order to obtain specimens for a histopathological examination, which resulted in a diagnosis of thymoma. In one case, surgical resection was conducted and the histological evaluation of the resected specimen confirmed thymoma type AB, consistent with the histology from the EBUS-TBNA specimen. As a safe and minimally invasive procedure, EBUS-TBNA may be considered for the diagnosis of mediastinal tumors, including thymoma.

Abstract
BACKGROUND Although the role of endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) in pulmonary sarcoidosis has previously been investigated, the determining factors in diagnosing sarcoidosis by EBUS-TBNA without rapid on-site evaluation (ROSE) are unclear. METHODS Patients with clinically and radiographically suspected sarcoidosis underwent EBUS-TBNA without ROSE in a prospective study. Presence of non-caseating epithelioid cell granulomas was pathologic evidence of sarcoidosis. RESULTS The EBUS-TBNA was performed in 120 patients, 111 of whom had confirmed sarcoidosis. For the patients with sarcoidosis (62 stage I, 49 stage II) EBUS-TBNA provided sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 93.69%, 100%, 100%, 56.25%, and 94.17%, respectively, in the diagnosis of sarcoidosis. Diagnostic yield of EBUS-TBNA for sarcoidosis was associated with disease stage, but not associated with serum angiotensin converting enzyme level, number of lymph node stations sampled per patient, or total number of passes performed per patient. At EBUS-TBNA, 284 mediastinal and hilar lymph nodes were aspirated in 111 patients. Multivariate logistic regression revealed that short-axis diameter and more than 1 needle pass per lymph node were independent risk factors associated with positive pathology. No major procedure-related complications were observed. CONCLUSIONS Endobronchial ultrasound-guided transbronchial needle aspiration is a safe procedure with high sensitivity for diagnosing sarcoidosis, having a higher diagnostic yield in stage I than stage II. To obtain a higher diagnostic yield of EBUS-TBNA in pulmonary sarcoidosis without ROSE, operators should select the largest mediastinal or hilar lymph node accessible and puncture with 3 to 5 passes.

Abstract
Effective use of the convex curvilinear ultrasound bronchoscope in the esophagus (EUS-B) is well described. EUS-B has not been described for diagnostic sampling of the left adrenal gland. We describe 6 cases of diagnostic fine-needle aspiration of the left adrenal gland using EUS-B. This capacity increases the diagnostic capabilities of the pulmonologist experienced in EUS-B.

Endobronchial ultrasound-guided transbronchial needle aspiration for diagnosis of sarcoidosis in clinically unselected study populations. Respirology 2014; 20:226-34. [PMID: 25477156 DOI: 10.1111/resp.12449] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2014] [Revised: 08/31/2014] [Accepted: 10/21/2014] [Indexed: 12/19/2022]
Abstract
Literature suggests that ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has excellent performance characteristics for diagnosis of sarcoidosis. However, many authors challenge the external validity of EBUS-TBNA results, as most studies were performed in referral centres by highly experienced investigators, and included populations with very high sarcoidosis prevalence. We performed a systematic review and meta-analysis to estimate the role of EBUS-TBNA for diagnosis of sarcoidosis in studies enrolling consecutive patients with lymphadenopathy detected at imaging studies, regardless of the suspected underlying clinical aetiology. The Pubmed, Embase, Cinahl, Web of Science and Cochrane Library databases were screened to identify the pertinent literature. Quality of eligible studies was assessed by Quality Assessment, Data Abstraction and Synthesis-2 criteria. Pooled diagnostic yield, sensitivity and specificity were calculated, and a summary receiver operating characteristic curve was constructed. Subgroup analysis was planned to identify possible sources of study heterogeneity. Fourteen studies, collectively involving 2097 patients, fulfilled eligibility criteria. The median prevalence of sarcoidosis was 15%. EBUS-TBNA had a pooled diagnostic yield of 0.79 (standard deviation, 0.24), a pooled sensitivity of 0.84 (95% confidence interval (CI), 0.79-0.88) and a pooled specificity of 1.00 (95% CI, 0.99-1.00). Only subgroup analysis exploring the influence of study design seemed to influence the observed inter-study heterogeneity for sensitivity, retrospective studies showing worst sensitivity than prospective ones. The results of EBUS-TBNA for diagnosis of sarcoidosis in clinically unselected populations are excellent and compare favourably with published results from studies conducted in selected populations. High-quality trials would be needed to evaluate factors possibly explaining the observed heterogeneity in sensitivity.
