Coccidioidomycosis causes significant morbidity in endemic areas. In the absence of sensitive diagnostic serologic testing, clinicians have increasingly relied on lung and lymph node biopsies for diagnosis. Recently, endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) has been shown to be an excellent sampling method for the diagnosis and staging of lung cancers, especially when combined with endoscopic ultrasound guided fine needle aspiration (EUS-FNA). We present 13 consecutive cases where EBUS-TBNA and/or EUS-FNA of pulmonary lymph nodes were performed as part of the workup for pulmonary coccidioidomycosis...

BACKGROUND: Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) has revolutionized the diagnostic approach to mediastinal diseases. Lesions located lateral to the pulmonary artery (trans-PA, Station 5), or in the lumen of the PA (intra-PA) are in the 'blind-spot' of EBUS. OBJECTIVES: We describe a case series where EBUS guided trans-pulmonary or intra-pulmonary aspiration (EBUS-TIPNA) was used for diagnosis. METHODS: Retrospective analysis of 10 patients who had EBUS-TIPNA over 3 years in 2 centers...

A 65-year-old man was diagnosed with granulomatosis with polyangiitis (GPA) at the age of 47, when cytoplasmic anti-neutrophil cytoplasmic antibody (C-ANCA) serology was positive, and he had multiple nodular shadows in both lungs. He had been treated with prednisolone, cyclophosphamide (CPA) and plasma exchange. At the age of 64, a nodular shadow was newly detected in the right lower lung field and serum tumour marker increased. Subsequent positron emission tomography/computed tomography scan demonstrated accumulations of fluorodexyglucose (FDG) in the same area, mediastinum lymph nodes, thoracic wall, right iliac bone, and right retroperitoneum...

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...

The use of endobronchial ultrasound trans-bronchial needle aspiration (EBUS-TBNA) as the initial diagnostic and staging procedure in patients with suspected, non-metastatic lung cancer has gained substantial support, and is now recommended by numerous guidelines. Whereas considerable attention has been pointed to the reductions in costs achieved by EBUS-TBNA, that has not been the case for some of its more significant benefits, namely the reduction of the diagnostic work-up time and its ability to accurately assess and restage lymph nodes, which were previously stated incorrectly by CT or PET scan...

Background/aim: Mediastinal lymph nodes are the second most commonly affected lymph nodes in tuberculous lymphadenitis. It is often difficult to diagnose tuberculosis in patients with lymphadenopathy without parenchymal lesions. The aim of this study was to describe the diagnostic utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in patients with isolated mediastinal tuberculous lymphadenitis (MTLA). Materials and methods: This study included 527 patients who had undergone EBUS-TBNA between December 2012 and December 2014...

INTRODUCTION: Next generation sequencing (NGS) testing of lung cancer is recommended by guidelines, and endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) often provides the only material available for testing. Previous studies have demonstrated successful NGS testing on cell block samples obtained by EBUS; however, cytology smears provide a more reliable sample with better DNA quality for testing. In this study, we aimed to determine the success rate of OncoScreen (50 gene) and OncoPlus (1213 gene) panel NGS testing of cytology samples obtained by EBUS utilizing 22- and 25-gauge needles...

The endobronchial ultrasound (EBUS) scope has been increasingly used in the gastrointestinal tract (EUS-B). Scientific data proves its efficacy and safety to provide a complete lung cancer staging, when combined with EBUS-TBNA, and in the diagnosis of para-esophageal lesions. There are multiple barriers to start performing EUS-B but probably the most important ones are related to knowledge and training, so new operators should follow a structured training curriculum. This review aims to reflect the best current knowledge regarding EUS-B and provide a road map to assist those who are incorporating the technique into their clinical practice...

Lung cancer is still underdiagnosed mainly due to lack of symptoms. Most patients are diagnosed in a late stage where unfortunately only systematic therapy can be applied. Fortunately in the last five years several novel therapies and combinations have emerged. However; in certain situations local therapeutics modalities have to be applied in order to solve emergency problems as in the case that we will present. Convex-EBUS probe was used along with a novel method of ventilation which keeps PCO2 concentration satisfyingly low...

Endobronchial ultrasound-guided needle aspiration (EBUS-TBNA) is a well-established procedure with high diagnostic yield and safety. However, the standard 22 gauge needles sometimes cause major bleeding particularly in hypervascular tumors like metastatic lung tumors from renal cell carcinoma (RCC). The 25 gauge needles are already introduced to endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), and are considered as one of the standard devices due to their comparable diagnostic outcome, lower complication risk, and the better manipulability...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has increasingly been performed for the diagnosis and staging of thoracic malignancies. Findings of a necrotic lymph node raise concern for infectious process and malignancy. A hypoechoic area on ultrasound/EBUS within a lymph node without blood flow is suggestive of pathologies like infections or malignancy. Inspection of the fluid could suggest a diagnosis; clear aspirates usually suggest bronchogenic or mediastinal cysts and purulent material suggests abscesses or necrotic lymph nodes...

BACKGROUND: Immunohistochemical (IHC) assessment of programmed death-ligand 1 (PD-L1) in non-small cell lung cancer (NSCLC) has become important since the development of anti-PD-1/-PD-L1 directed drugs. Various PD-L1 antibodies and cut-offs have been used in different trials to predict response to these drugs, thus comparison of those studies is difficult. We compared PD-L1 mRNA expression measured by RT-qPCR with PD-L1 protein expression evaluated by IHC. Moreover, we investigated the impact of different tumour tissue acquisition methods on the reliability of PD-L1 measurement techniques...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been widely used for diagnosis and mediastinal lymph nodes staging in patients with suspicious lung cancer. Ultrasound elastography is a novel sonographical technique that can evaluate tissue compressibility. The aim of the present study was to investigate the diagnostic yield of elastography for differentiating malignant and benign mediastinal lymph nodes. Conventional EBUS B-mode features, including size, shape, border distinction, echogenicity, central hilar structure with central blood vessel and coagulation necrosis were also evaluated...

We report findings for a patient that underwent endobronchial ultrasound (EBUS) guided transbronchial needle aspiration (TBNA) for diagnostic purposes after an abnormal chest CT. The patient initially presented with cough and shortness of breath. Chest CT revealed a 6 cm soft tissue mass with mildly enlarged right hilar lymph nodes (LNs) and a small right sided pleural effusion. Based on these radiologic findings, the patient underwent an EBUS guided FNA of the mass. To our surprise, the mass was hypoechoic by EBUS and on aspiration, the syringe filled with yellow fluid...

BACKGROUND: Whether the use of rapid on-site cytologic evaluation (ROSE) increases the diagnostic yield of transbronchial needle aspiration (TBNA) remains unclear. This article is a systematic review of studies describing the utility of ROSE in subjects undergoing TBNA. METHODS: The study included a systematic review of the PubMed, Embase, and Scopus databases for randomized controlled trials investigating the diagnostic yield of conventional transbronchial needle aspiration (c-TBNA) or endobronchial ultrasound (EBUS)-TBNA, with or without ROSE, in subjects with mediastinal lymphadenopathy...

Endobronchial Ultrasound (EBUS) with the two modalities curved and radial EBUS significantly improved the diagnostics in several pulmonary diseases. The examination and staging of mediastinal and hilar lymph nodes in patients with known or suspected lung malignancy as well as the evaluation of unknown pulmonary or mediastinal lesions can be achieved with minimal invasive means when using EBUS. More invasive surgical procedures for diagnostic purposes can be omitted. The diagnostic yield also increases when EBUS is applied in sarcoidosis or mediastinal lymph node tuberculosis but only to some extend in case of lymphoma...

INTRODUCTION: The quality of tissue acquisition during Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a major determinant of the diagnostic yield of the procedure. In the tissue button (TB ) technique the retrieved cellular specimen is fixed in ethanol and subsequently scraped from slide using surgical blade into formaldehyde and processed like ordinary tissue biopsy thus potentially increasing its diagnostic value. OBJECTIVES: To retrospectively evaluate the diagnostic yield of a TB technique in patients undergoing EBUS-TBNA for various malignant and benign conditions...

BACKGROUND: In breast cancer patients, the expression statuses of oestrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) are crucial in the choice of treatment. Receptor expression in metastatic lesions can differ from the primary tumour. The aim of our study was to analyse the utility of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to obtain samples allowing the identification of ER, PR and HER2 expression in patients with mediastinal metastases of breast cancer...
