The treatment of non-small cell lung cancer is largely dependent on accurate staging in order to determine appropriate therapy. Despite advances in imaging, such as computed tomography and positron emission tomography, invasive mediastinal staging is frequently needed to rule out mediastinal involvement prior to curative-intent stereotactic ablative radiotherapy or surgical resection. Surgical mediastinal staging with mediastinoscopy, or anterior mediastinotomy, were traditionally considered the gold standard for invasive mediastinal staging...

The diagnosis and staging of patients with lung cancer has relied on tissue sampling. Endobronchial ultrasound (EBUS) is a minimally invasive procedure for the rapid and safe acquisition of tissue and can be done easily and repeatedly. EBUS transbronchial needle aspiration (TBNA) is now the standard for diagnosis of mediastinal and hilar lymphadenopathy and should be considered in patients who have a high probability of lymph node metastases without systemic involvement. EBUS also provides guidance for biopsy of peripheral lung lesions...

Lung cancer is the leading cause of cancer-related deaths worldwide with an overall 5-year survival rate of 17% after diagnoses. Indeed many patients tend to have a very poor prognosis, due to being diagnosed at an advanced stage. Conversely patients who are diagnosed at an early stage have a 5-year survival >70%, indicating that early detection of lung cancer is crucial to improve survival. Although flexible bronchoscopy is a relatively non-invasive procedure for patients suspected of having lung cancer, only 29% of carcinoma in situ (CIS) and 69% of microinvasive tumors were detectable using white light bronchoscopy (WLB) alone...

BACKGROUND: Transbronchial biopsy (TBB) using radial endobronchial ultrasound with a guide sheath (REBUS-GS) has improved the diagnosis of peripheral pulmonary lesions (PPLs). Because of the high cost of the GS, REBUS with distance (REBUS-D) has certain advantages. The aim of this study was to compare the diagnostic yield of the REBUS-GS and REBUS-D by thin bronchoscopy for PPLs. METHODS: Patients with PPLs were enrolled in a prospective randomized crossover study from August 2014 and July 2015...

INTRODUCTION: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the initial modality of choice in sampling mediastinal lymphadenopathy. It is possible to obtain both cytological and histological samples using both 21-gauge and 22-gauge EBUS-TBNA needles. The current study was undertaken to compare the diagnostic yield of cytology and histology samples obtained by the same EBUS-TBNA 21-gauge needle. PATIENTS AND METHODS: One hundred sixty-six consecutive patients who underwent EBUS-TBNA with a 21-gauge EBUS-TBNA needle over a period of 3 years were included in this retrospective analysis...

OBJECTIVES: The superior performance of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis and staging of malignancy has been demonstrated, with some investigators suggesting the same for sarcoidosis. The role of EBUS-TBNA in the diagnosis of histoplasmosis is not clear, however. In this study we estimate the diagnostic yield of conventional TBNA (cTBNA) and EBUS-TBNA for the diagnosis of histoplasmosis in patients with mediastinal lymphadenopathy...

BACKGROUND: Due to absence of visible endobronchial target, the diagnostic yield of flexible bronchoscopy for peribronchial lesions has been unsatisfactory. Convex probe endobronchial ultrasound (CP-EBUS) has allowed for performing real-time transbronchial needle aspiration (TBNA) of enlarged hilar and mediastinal lymph nodes and therefore could also be used as a means of diagnosing proximal peribronchial lesions. METHODS: We retrospectively analyzed the results related to 72 patients who underwent CP-EBUS for peribronchial lesions without endobronchial involvement and adjacent to three-grade bronchi based on chest computed tomography (CT) scan...

We describe 2 cases of Ga-PSMA PET/CT in prostate cancer patients. Both cases demonstrated symmetrical bilateral involvement of mediastinal and hilar lymph nodes besides findings in relation with prostatic disease. In both cases, endobronchial ultrasound-guided biopsy showed that the involvement of the thoracic lymph nodes was caused by nonnecrotic granulomas compatible with sarcoidosis. The cases demonstrated that increased Ga-PSMA uptake can be seen in lymph nodes with active sarcoidosis, with images mimicking those well known from FDG PET/CT...

BACKGROUND: Patients with non-small cell lung cancer (NSCLC) being evaluated for stereotactic ablative body radiotherapy (SABR) are typically staged noninvasively with positron emission tomography/computed tomography (PET/CT). Incorporating endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) into the staging workup of these patients has not been evaluated. Our primary objective was to compare the performance of PET/CT with EBUS-TBNA for intrathoracic nodal assessment among SABR-eligible patients...

BACKGROUND : As resident "index" procedures change in volume due to advances in technology or reliance on simulation, it may be difficult to ensure trainees meet case requirements. Training programs are in need of metrics to determine how many residents their institutional volume can support. OBJECTIVE : As a case study of how such metrics can be applied, we evaluated a case distribution simulation model to examine program-level mediastinoscopy and endobronchial ultrasound (EBUS) volumes needed to train thoracic surgery residents...

BACKGROUND: Routine collection of cytology specimens from bronchial aspirate or washing is thought to increase the sensitivity of bronchoscopy for diagnosing malignant lung lesions. However, the added value of this practice has not been reappraised in a context of changing epidemiology. PATIENTS AND METHODS: In a retrospective monocenter study, all cytology specimens from bronchial aspirate or washing collected between May 2011 and December 2014 and the corresponding patients' files were reviewed...

BACKGROUND: Transesophageal introduction of the endobronchial ultrasound (EBUS) videobronchoscope allows pulmonologists to perform endoscopic ultrasound fine-needle aspiration (EUS-B-FNA) of mediastinal lesions. Safety, diagnostic accuracy, and feasibility of EUS-B-FNA in evaluation of pulmonary parenchymal lesions are not established. METHODS: All patients undergoing pulmonologist-performed EUS-B-FNA of parenchymal lung lesions at 2 tertiary centers were included in this prospective observational cohort study...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) as a standalone modality is superior to conventional TBNA (c-TBNA) for the diagnosis of sarcoidosis. However, the overall yield is not different if combined with endobronchial biopsy (EBB) and transbronchial lung biopsy (TBLB). The utility of rapid on-site evaluation (ROSE) in a comparative evaluation of EBUS-TBNA versus c-TBNA for the diagnosis of sarcoidosis has not been previously evaluated. METHODS: Eighty patients with suspected sarcoidosis were randomized 1:1:1:1 into 4 groups: c-TBNA without ROSE (TBNA-NR), c-TBNA with ROSE (TBNA-R), EBUS-TBNA without ROSE (EBUS-NR), and EBUS-TBNA with ROSE (EBUS-R)...

BACKGROUND: Standard instructions for biopsy using the convex curvilinear endobronchial ultrasound scope include visualization and adjustment of the sheath housing the biopsy needle before every puncture. In our practice, we pre-set this relationship before inserting the endobronchial ultrasound scope and leave it fixed for every puncture. OBJECTIVE: We postulated that this approach is more efficient than repeated re-adjustment and aimed to show that it would not increase the frequency of endobronchial ultrasound scope damage...
