BackgroundMediastinoscopy is considered the gold standard for evaluating mediastinal lymph nodes. However, endobronchial ultrasound–guided transbronchial needle aspiration has lately offered a less invasive alternative, with the ability to obtain nodal samples under direct visualization. Recent literature found an early learning curve for this technique. We present the initial experience of 4 thoracic surgeons with the procedure.Materials and MethodsA retrospective chart review was performed on the first 51 patients on whom an endobronchial ultrasound-guided transbronchial needle aspiration was performed from January 5, 2007, to July 24, 2008. This group included 43 patients with a history or known diagnosis of malignancy as well as 8 patients with a presumed sarcoidosis diagnosis. All negative results were confirmed with mediastinoscopy. The technique's sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were assessed.ResultsA total of 73 lymph nodes underwent biopsy in 51 patients. These individuals included 34 men and 17 women, with an average age of 62 years (range, 21-89 years). No surgical or postoperative complications were noted. Overall, a correct diagnosis was established in 88% of the patients (45 of 51). After the first 25 cases (a mean of 6 cases per surgeon), a technique modification was adapted to increase diagnostic yield. The first 25 cases had a 72.22% sensitivity and 80% accuracy, whereas the last 26 cases had a 95.45% sensitivity and 96.15% accuracy (P = .07).ConclusionEndobronchial ultrasound–guided transbronchial needle aspiration is a quickly mastered technique that offers a safe, minimally invasive, and accurate means to evaluate mediastinal lymph nodes.
