BACKGROUND: Endobronchial ultrasound (EBUS) elastography is a new imaging procedure for describing the elasticity of intrathoracic lesions and providing important additional diagnostic information. OBJECTIVES: The aim of this study was to utilize the feasibility of qualitative and quantitative methods to evaluate the ability of EBUS elastography to differentiate between benign and malignant mediastinal and hilar lymph nodes (LNs) during EBUS-guided transbronchial needle aspiration (EBUS-TBNA)...

Fluoroscopy-guided transbronchial forceps biopsy has a low diagnostic yield in patients with radiographic suspicion of interstitial lung disease. Cryobiopsy has a higher diagnostic yield likely due to preserved lung architecture and larger biopsies; however, there is an increased risk of major airway bleeding and pneumothorax. Simultaneous use of endobronchial balloon blocker allows for containment of bleeding after cryobiopsy to the affected lobe. In the current article we describe use of radial ultrasound in identification of a target lung parenchyma without a major blood vessel adjacent to distal bronchi...

Stereotactic body radiotherapy (SBRT) is an effective method for the treatment of localized primary lung tumors. Cyberknife, a highly accurate SBRT technique, follows the target during respiratory cycles using a metallic fiducial marker (FM) previously inserted into the lesion. Various methods have been described for the placement of an FM in peripheral pulmonary lesions; however, none of these is appropriate for mediastinal or hilar tumors. The placement of FMs in central lesions to achieve accurate SBRT is particularly relevant due to their higher mobility during respiratory and cardiac cycles...

Malignant neoplasms frequently cause vertebral metastases. Traditionally, either image-guided percutaneous biopsy or open biopsy has been performed for sampling specimens for the definitive diagnosis. We herein report a case with suspected multiple metastases but unknown primary, who underwent endobronchial ultrasound-guided transbronchial needle aspiration for mediastinal lymph nodes with negative results by rapid onsite cytologic evaluation, followed by the transesophageal approach with the ultrasound bronchoscope for the vertebral body lesion at the same setting that provided a definitive diagnosis of metastatic hepatocellular carcinoma...

We report the findings for 2 patients with a fluid-fluid level seen on endobronchial ultrasound (EBUS) images of bronchogenic cysts. The EBUS images demonstrated a well-circumscribed cyst with a fluid-fluid level showing an anechoic upper part and a relatively hyperechoic lower part. A fluid-fluid level on EBUS imaging of a bronchogenic cyst, which can help confirm the cystic nature of the lesion, has not been previously reported. EBUS-based confirmation of these cysts using fluid-fluid levels may help avoid unnecessary aspiration of the lesions...

BACKGROUND: Linear endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) represents a pivotal innovation in interventional pulmonology; determining the best approach to guarantee systematic and efficient training is expected to become a main issue in the forthcoming years. Virtual reality simulators have been proposed as potential EBUS-TBNA training instruments, to avoid unskilled beginners practicing directly in real-life settings. A validated and perfected simulation program could be used before allowing beginners to practice on patients...

Isolated hilar and mediastinal recurrence (IMHR) following external beam radiation therapy (EBRT) in patients with lung cancer is common. These patients do not have many treatment options and are usually offered palliative chemotherapy or best supportive care. Endobronchial ultrasound (EBUS)-guided intratumoral injection of cisplatin (ITC) is a novel approach for these patients. The procedure is performed under conscious sedation. The lesion is located with a bronchoscopy using EBUS, and a 22-gauge EBUS needle is advanced through the working channel of the scope and locked in position...

OBJECTIVE: To assess the cost-effectiveness of various modes of mediastinal staging in non-small cell lung cancer (NSCLC) in a single-payer health care system. METHODS: We performed a decision analysis to compare the health outcomes and costs of 4 mediastinal staging strategies: no invasive staging, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), mediastinoscopy, and EBUS-TBNA followed by mediastinoscopy if EBUS-TBNA is negative. We determined incremental cost effectiveness ratios (ICER) for all strategies and performed comprehensive deterministic sensitivity analyses using a willingness to pay threshold of $80,000/quality adjusted life year (QALY)...

A 61-year-old man who was an ex-heavy smoker presented to our ambulatory care centre with a 4-week history of dyspnoea on mild exertion. 2 weeks prior to his symptoms, he had developed right-sided cervical herpes zoster for which he was prescribed oral acyclovir by his general practitioner. On examination, a rash over the right C4-5 dermatomes was noted and dullness on percussion of the right mid and lower zones with markedly reduced air entry. His chest radiograph showed a raised right hemi-diaphragm with associated right middle and lower lobe collapse...

INTRODUCTION    There are no widely accepted standards of diagnosis of sarcoidosis.  OBJECTIVES    The aim of the study was to assess the relative diagnostic yield of endobronchial ultrasound needle aspiration (EBUS-NA) and endoscopic ultrasound needle aspiration (EUS-NA), and to compare them with the standard diagnostic techniques, i.e. endobronchial biopsy (EBB), transbronchial lung biopsy (TBLB), transbronchial needle aspiration (TBNA) and mediastinoscopy.  PATIENTS AND METHODS    A prospective randomized study including consecutive patients with clinical diagnosis of stage I or II sarcoidosis...

REVIEW
Christoph F Dietrich
Endobronchial ultrasound (EBUS) has gained importance for mediastinal lymph node staging. Contrast-enhanced EBUS is so far not a discussed technique including contrast-enhanced high mechanical index (MI)-EBUS and potentially contrast-enhanced low MI-EBUS. Possible use could include characterization of mediastinal lymph nodes for better selection of biopsies, differential diagnosis of the primary tumor, and evaluation of thrombosis or tumor in vein infiltration.

PURPOSE OF REVIEW: As demonstrated by the recent therapeutic advances in nonsmall cell lung cancer (NSCLC), a personalized approach can considerably reduce its mortality. RECENT FINDINGS: Molecular tests identifying genetic mutations in NSCLC have led to a shift towards more effective and personalized therapies targeted to these alterations. Adequate tissue is required for diagnosing, subcharacterizing, and genotyping NSCLC by morphological, immunohistochemical, and molecular techniques...

Surgicel(®) (Ethicon, North Ryde, NSW, Australia) is an absorbable sheet of oxidized cellulose polyanhydroglucuronic acid polymer used as an hemostatic in cardiovascular and thoracic surgery. In some cases, the retained material may cause foreign body granulomatous reactions and simulate tumor recurrence, an abscess, an hematoma, or an infection. We report the case of a 55-year-old patient who was operated of a lung adenocarcinoma. In the thoracic computed tomography scan 1 year after the surgery, a right paratracheal lymph node was detected, so endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was performed suspecting recurrence of the tumor...

INTRODUCTION: Lung cancer staging has recently evolved to include endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for nodal assessment. AIM: Evaluate the performance and safety of EBUS-TBNA as a key component of a staging algorithm for non-small cell lung carcinoma (NSCLC) and as a single investigation technique for diagnosis and staging of NSCLC. METHODS: Patients undergoing EBUS-TBNA for NSCLC staging at our institution between April 1, 2010 and December 31, 2014 were consecutively included with prospective data collection...

Mediastinitis is a rare complication of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Recent reports of infectious complications following EBUS-TBNA involved oropharyngeal bacteria. Here, we report 2 unusual cases of post-EBUS-TBNA mediastinitis involving Streptococcus pneumoniae and Pseudomonas aeruginosa, which were likely the result of direct inoculation of the organisms at the time of transbronchial needle aspiration. The first case was successfully treated with computed tomography-guided drainage and antibiotics, whereas the second case had >50% distal tracheal obstruction and near total occlusion of the left main stem bronchus, requiring rigid bronchoscopy, stent placement, debulking, and antibiotics...
