Endoscopic Ultrasound
All endoscopic ultrasound procedures were performed as a part of routine clinical care for patients with known or suspected lung cancer. All patients had chest computed tomography (CT) scans before the procedure, and most had positron emission tomography (PET) or PET/CT studies available. The decision regarding which
Lymph Node Sampling
Between March 9, 2006, and January 6, 2009, endoscopic ultrasound was performed on 200 patients (EUS, 62; EBUS, 103; EUS and EBUS, 35). Of these, 136 (EUS, 43; EBUS, 71; EUS + EBUS, 22) had NSCLC proven either before the procedure, as a result of the procedure, or at subsequent resection. As shown in Table 2, a total of 379 mediastinal lymph node stations were sampled in these 136 patients (mean, 2.8 per patient). Ninety-three patients had EBUS with sampling of 271 mediastinal lymph node
Comment
Introduction of endoscopic ultrasound into clinical practice is transforming invasive mediastinal staging of patients with NSCLC. Increasingly gastroenterologists and pulmonologists are performing a function that historically has been performed almost exclusively by thoracic surgeons. In a recent review of practice patterns in lung cancer care, Little and colleagues [9] discovered that there was wide variability in the practice of mediastinoscopy. On the basis of a survey of data on almost

2014, Journal of Thoracic and Cardiovascular SurgeryCitation Excerpt :Other possible reasons include procedural or technical issues, such as the number of aspirations (2 aspirations per lesion in our study) or the level of the examiner's skill. Previous studies of EBUS-TBNA for mediastinal staging of NSCLC have recommended ≥2 needle aspirations per lymph node station30 and >2 lymph node stations.31 However, optimal results were obtained by 3 needle aspirations30 and 4 lymph node stations31 in those studies.

2013, ChestCitation Excerpt :Similarly, smaller lymph nodes and trainee involvement in the procedure did not affect outcomes. These findings support the standard use of complete mediastinal lymph node staging for non-small cell lung cancer with EBUS regardless of lymph node size or location because previous reports suggested that sampling more lymph nodes is associated with an increase in diagnostic yield.39 This study adds to the growing body of evidence evaluating the impact of hospital variables on bronchoscopic outcomes.
