A 65-year-old woman, never smoker, with medical history of hypertension, nonischemic cardiomyopathy, and moderate pulmonary hypertension presented with symptomatic bilateral pleural effusions. Thoracentesis revealed a lymphocyte predominant transudate and was negative for malignancy, microbiologic cultures were negative for an infectious cause. Chest tomography showed mediastinal and bilateral hilar lymphadenopathy, lymph node biopsy with endobronchial ultrasound-guided transbronchial needle aspiration showed non-necrotizing granulomas compatible with sarcoidosis...

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: The propofol use for moderate sedation (MS) during endobronchial ultrasound (EBUS) bronchoscopy is primarily restricted for use by an anesthesiologist because of safety concerns. The goals of this study were to demonstrate the safety and the diagnostic yield of the use of propofol by bronchoscopists and trained endoscopy nurses during EBUS bronchoscopy without intubation. METHODS: We tested a bolus propofol administration protocol targeting MS for EBUS bronchoscopy...

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...

In diagnosing peripheral pulmonary lesions (PPL), radial endobronchial ultrasound (R-EBUS) is emerging as a safer method in comparison to CT-guided biopsy. Despite the better safety profile, the yield of R-EBUS remains lower (73%) than CT-guided biopsy (90%) due to the smaller size of samples. We adopted a hybrid method by adding cryobiopsy via the R-EBUS Guide Sheath (GS) to produce larger, non-crushed samples to improve diagnostic capability and enhance molecular testing. We report six prospective patients who underwent this procedure in our institution...

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...

BACKGROUND: Peripheral pulmonary lesions (PPLs) pose a diagnostic challenge, and the optimal investigation in many such cases remains unclear. Computed tomography (CT)-guided percutaneous needle biopsy (CT-PNB) has been the modality of choice for such lesions with a high diagnostic accuracy but with high rates of pneumothorax. Endobronchial ultrasound (EBUS) with a radial probe is an alternate diagnostic modality with increased diagnostic yield of bronchoscopy in the evaluation of PPL...

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: Virtual fluoroscopy (VF) is a novel guided technique that provides ray summation images of target lesions similar to X-ray fluoroscopy. Endobronchial ultrasound with a guide sheath (EBUS-GS) is a useful modality for imaging ground-glass nodules (GGNs) but is not ideal for GGNs that cannot be detected on X-ray fluoroscopy. We evaluated whether the addition of VF to EBUS-GS improved the diagnostic yield. Methods: Consecutive patients who had undergone diagnostic bronchoscopy for GGNs that were not detected on X-ray fluoroscopy between September 2012 and January 2016 were retrospectively enrolled...

Background: The current standard methods for detecting pulmonary artery diseases are pulmonary artery enhanced computed tomography (CT) scan and pulmonary arteriography. However, some patients cannot tolerate these procedures for various reasons. The present study aimed to investigate the feasibility and operation process of endobronchial ultrasound (EBUS) in exploring the pulmonary artery. Methods: Based on normal contrast-enhanced chest CT images, the sites and process for exploring the pulmonary arteries were established...

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: Endoscopic ultrasound (EUS) allows access to the inferior mediastinal lymph node stations (8 and 9) which are beyond the reach of endobronchial ultrasound (EBUS). The addition of EUS to EBUS procedures requires cost and resource investment. This study sought to describe the prevalence of station 8/9 nodal metastases from intra-operative lymph node sampling in a UK region where routine pre-operative EUS is not available. METHODS: A retrospective review of all lung cancer resections at the University Hospital South Manchester from 2011 to 2014...

Endobronchial metastasis occurs in only 2%-5% of non-pulmonary cancers. Here we report on an 84-year-old woman who presented with breathlessness and light-headedness while on holiday in Australia, 2 years post-treatment for endometrial cancer. Initial CT pulmonary angiogram identified a soft tissue mass in the left hemithorax. A chest radiograph performed after repatriation was consistent with a large left pleural effusion, but bedside ultrasound showed a lobulated mass involving the left hemidiaphragm. A pleural procedure in the traditional 'triangle of safety' would have resulted in inadvertent puncture of the underlying mass...

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...

BACKGROUND: With the application of high resolution computed tomography (CT), a large number of peripheral lung lesions were found. It put forward new challenge on clinical diagnosis and treatment for these peripheral lung lesions. Electromagnetic navigation bronchoscopy (ENB) and radial endobronchial ultrasound probe (R-EBUS) are new technologies used for the diagnosis of peripheral lung lesions. The aim of this study is to explore the application value of ENB combined with R-EBUS in the diagnosis of peripheral pulmonary lesions...

The standard approach to staging of lung cancer in patients with pleural effusion (clinical M1a) is thoracentesis followed by pleural biopsies if the cytologic analysis is negative. If pleural biopsy findings are negative, endobronchial ultrasound-guided transbronchial needle aspiration is used to complete the staging process and, in some cases, obtain diagnosis. In this case series we report 7 patients in which a combined procedure was performed for staging of known or suspected lung cancer. We found that the combined approach was both feasible and safe in this case series...
