ABSTRACT
BACKGROUND AND OBJECTIVE:
Linear endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has proven useful for sampling mediastinal masses and nodes and for staging lung cancer. The aim of this study was to assess the usefulness of this diagnostic tool in patients with indications of mediastinal disease that could not be diagnosed by noninvasive methods or white light bronchoscopy. PATIENTS ANDMETHODS:
All patients undergoing linear EBUS-TBNA for the diagnosis of mediastinal masses and/or adenopathy at our endoscopy unit were included in the study. Diagnoses obtained by linear EBUS-TBNA or any surgical technique performed after a nondiagnostic EBUS-TBNA were considered as final.RESULTS:
In the study population of 128 patients with a mean (SD) age of 62.0 (11.2) years, a total of 294 TBNAs were performed on 12 masses and 282 nodes. Satisfactory samples were obtained in 11 cases (91.7%) from masses and in 233 cases (82.6%) from nodes. Linear EBUS-TBNA was diagnostic, obviating the need for mediastinoscopy in 115 patients (diagnostic sensitivity, 89.8%). The technique confirmed the diagnosis in 85 of the 94 patients with cancer (90.4%), in 8 of the 10 patients with tuberculosis (80.0%), and in the 5 patients with sarcoidosis.CONCLUSIONS:
Linear EBUS-TBNA is a useful diagnostic tool in patients with mediastinal disease for whom a pathologic diagnosis is not achieved by noninvasive methods or white light bronchoscopy.
