EBUS TBNA

INTRODUCTION: Endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TMC), a novel technique, has been reported to improve the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for mediastinal lesions in recent studies. Current literature suggests that this procedure has greater diagnostic efficacy compared to conventional EBUS-TBNA. This systematic review and meta-analysis aimed to evaluate the diagnostic yield and complications associated with EBUS-TMC in comparison to EBUS-TBNA, thereby exploring the potential of this novel technique in enhancing the diagnostic utility for mediastinal lesions...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a revolutionary tool for the diagnosis and staging of mediastinal disorders. Nevertheless, its diagnostic capability is reduced in certain disorders such as lymphoproliferative diseases. EBUS-guided transbronchial mediastinal cryobiopsy (EBUS-TBMC) is a novel technique that can provide larger samples with preserved tissue architecture, with an acceptable safety profile. In this case report, we present a middle-aged gentleman with a huge anterior mediastinal mass and bilateral mediastinal and hilar lymphadenopathy...

INTRODUCTION: Advanced diagnostic bronchoscopy includes endobronchial ultrasound (EBUS) guided transbronchial lung and lymph node biopsies, CT navigation and robotic bronchoscopy. Interventional bronchoscopy refers to procedures performed for therapeutic purposes such as balloon dilation of the airway, tissue debulking, cryotherapy, removal of foreign bodies and insertion of endobronchial valves [1]. For adult patients, these procedures are standard of care [2, 3]. Despite a lack of formalized training, there are numerous case reports and case series describing the use of advanced diagnostic and interventional bronchoscopy techniques in children...

Sarcoidosis, a multi-organ system disease, often presents insidiously. Thrombocytopenia in sarcoidosis is frequent because of hypersplenism, granulomas infiltrating the bone marrow, or immune thrombocytopenia (ITP). The diagnosis of ITP relies on exclusionary criteria, given the absence of a definitive laboratory diagnostic feature. In the era prior to modern ITP management, sarcoidosis-associated ITP was known to manifest severely, often showing resistance to treatment and an increased risk of mortality. In this case, we present a young male who was admitted to a district hospital's emergency room, displaying symptoms of hematuria, gingival bleeding, and a petechial rash...

BACKGROUND: Observational data suggest that the 19-gauge (G) needle for endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) offers a higher diagnostic yield in sarcoidosis than the 22-G needle. No randomized trial has compared the yield of the two needles. METHODS: We randomized consecutive subjects with suspected sarcoidosis and enlarged thoracic lymph nodes to undergo EBUS-TBNA with either the 19-G or the 22-G needle. We compared the study groups for diagnostic sensitivity (primary outcome) assessed by the yield of granulomas in subjects finally diagnosed with sarcoidosis...

INTRODUCTION: The recently introduced World Health Organization (WHO) Reporting System for Lung Cytopathology presents 5 diagnostic categories with corresponding risk of malignancy (ROM) and management protocols. This study uses the system to categorize our institutional respiratory tract cytology specimens, evaluating ROM and diagnostic accuracy for each category. MATERIALS AND METHODS: In a retrospective analysis (May 2020 to August 2021), the following respiratory cytology specimens were classified based on the WHO categories: bronchoalveolar lavage (BAL), bronchial wash/bronchial brushings (BB/BW), endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), fine-needle aspiration cytology (FNAC), sputum, biopsy imprint (BI), and endotracheal wash...

A 75-year-old male visited our hospital with bilateral hilar lymph node swelling detected on chest radiography during an annual medical checkup. Chest computed tomography revealed swelling of multiple hilar mediastinal lymph nodes. Histopathological and immunohistochemical examinations of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) specimens from the hilar lymph nodes revealed amyloid deposition. Bilateral hilar and mediastinal lymphadenopathies can be the first manifestations of amyloidosis diagnosed using EBUS-TBNA...

BACKGROUND: Systematic mediastinal lymph node staging by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) improves accuracy of staging in patients with early-stage non-small-cell lung cancer (NSCLC). However, patients with locally advanced NSCLC commonly undergo only selective lymph node sampling. This study aimed to determine the proportion of patients with locally advanced NSCLC in whom systematic endoscopic mediastinal staging identified PET-occult lymph node metastases, and to describe the consequences of PET-occult disease on radiotherapy planning...

INTRODUCTION: Endobronchial ultrasound-transbronchial needle aspiration (EBUS-TBNA) has a cardinal role in the diagnosis and staging of non-small cell lung cancer (NSCLC), providing an accurate nodal staging in a less invasive way than surgical biopsy. The aim of this study was to assess the diagnostic accuracy of EBUS-TBNA in the pre-operative NSCLC mediastinal staging, as well as to evaluate EBUS-TBNA specificity and sensibility in our cohort. METHODS: We retrospectively analyzed data of NSCLC patients who underwent EBUS-TBNA followed by major pulmonary resection between January 2020 and December 2022...

A 49-year-old man, a farmer, had been experiencing coughing, phlegm, and difficulty breathing for 2 months. He underwent a CT scan at a local hospital that showed a mediastinal mass. Bronchoscopy showed no obstruction in the tracheal lumen, and an endobronchial ultrasound-guided transbronchial fine needle aspiration (EBUS-TBNA) biopsy was performed on the mediastinal mass. The cytologic smear of the mediastinal mass showed a few atypical epithelial cells; the possibility of a tumor could not be ruled out...

BACKGROUND: Tularaemia is a zoonotic disease caused by Francisella tularensis, a highly virulent bacterium that affects humans and small wild animals. It is transmitted through direct contact with infected animals or indirectly through contaminated soil, water or arthropod bites (e.g. ticks). Primary thoracic manifestations of tularaemia are infrequent and, therefore, a diagnostic challenge for clinicians. METHODS: We report six tularaemia cases with exclusively thoracic involvement diagnosed in a clinic for pulmonary diseases in Bavaria between 10/2020 and 02/2022...

BACKGROUND: Endobronchial ultrasound (EBUS) sonographic features help identify benign/malignant lymph nodes while conducting transbronchial needle aspiration (TBNA). This study aims to identify risk factors for malignancy based on EBUS sonographic features and to estimate the risk of malignancy in lymph nodes by constructing a nomogram. METHODS: 1082 lymph nodes from 625 patients were randomly enrolled in training ( n  = 760) and validation ( n  = 322) sets...

BACKGROUND: Lung cancer is a common malignant tumor of respiratory system. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a valuable tool for the diagnosis and staging of lung cancer. EBUS-TBNA is predominantly performed under local anesthesia or conscious sedation. However, the diagnostic performance of EBUS-TBNA under general anesthesia and in conjunction with rapid on-site evaluation (ROSE) remains uncertain. This study aims to investigate the value of general anesthesia and ROSE in the diagnosis of lung cancer with EBUS-TBNA...

Mediastinal masses present a diagnostic challenge due to their similar imaging characteristics, making distinguishing between noninfectious and infectious processes or malignancies difficult. A mediastinal abscess can result in severe life-threatening infections if left untreated. Traditional treatment approaches involve surgical debridement and drainage; however, emerging endobronchial techniques, such as endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), offer a less-invasive means of diagnosing and managing abscesses...

OBJECTIVES: This study aimed to compare the high-flow nasal oxygen (HFNO) and supraglottic airway device (SAD) techniques in oncological patients undergoing endobronchial ultrasound (EBUS) and transbronchial needle aspiration (TBNA) to evaluate the efficacy of HFNO in them. METHODS: This pilot study was conducted at Sultan Qaboos Comprehensive Cancer Care and Research Centre, Muscat, Oman, from May 2022 to March 2023. Patients undergoing EBUS TBNA under moderate sedation were quasi-randomised into the HFNO and SAD groups...

BACKGROUND: The role of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in staging mediastinal and hilar lymph nodes in non-small cell lung cancer (NSCLC) is well established. However, evidence of its diagnostic utility in other pathologies-such as lymphoma-remains inadequate. This retrospective observational study aims to determine the diagnostic yield of EBUS-guided miniforceps biopsy (EBUS-MFB) compared to EBUS-TBNA in both malignant and nonmalignant conditions...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an innovative tool for diagnosing mediastinal diseases. We investigated the factors affecting the diagnostic yield of EBUS-TBNA and evaluated whether the effects of these factors (number of biopsies, core tissue acquisition rate, and diameter and volume of tissue) vary depending on computed tomography (CT) and/or positron emission tomography (PET)/CT results. METHODS: We retrospectively analyzed lung cancer patients who underwent EBUS-TBNA at Korea University Ansan Hospital (January 2019-December 2022)...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is often the only source of tumor tissue from patients with advanced, inoperable lung cancer. EBUS-TBNA aspirates are used for the diagnosis, staging, and genomic testing to inform therapy options. Here we extracted DNA and RNA from 220 EBUS-TBNA aspirates to evaluate their suitability for whole genome (WGS), whole exome (WES), and comprehensive panel sequencing. For a subset of 40 cases, the same nucleic acid extraction was sequenced using WGS, WES, and the TruSight Oncology 500 assay...

BACKGROUND: Combined endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and endoscopic ultrasound-guided tissue acquisition (EUS-TA) are accurate procedures for the diagnosis and staging of mediastinal lymph nodes (MLNs) in lung cancer. However, the respective contribution of separate and combined procedures in diagnosis and staging has not been fully studied. The aim of this study was to assess their respective performances. METHODS: Patients with suspected malignant MLNs in lung cancer or recurrence identified by PET-CT who underwent combined EBUS-TBNA and EUS-TA were retrospectively reviewed...
