Multicenter StudyEUS-guided fine needle aspiration in mediastinal lymphadenopathy of unknown etiology.
EUS-guided fine needle aspiration (EUS-FNA) has significantly expanded the diagnostic capability of GI EUS. FNA technology can also be helpful in the diagnosis of non-GI disorders. The role of EUS-guided FNA in the diagnosis of mediastinal lymphadenopathy of unknown etiology has not been described. The aim of this study was to evaluate the diagnostic accuracy and impact on subsequent evaluation and therapy of EUS-FNA in mediastinal lymphadenopathy of unknown cause. ⋯ EUS-FNA in patients with mediastinal lymphadenopathy is safe and guides subsequent therapy in the great majority of cases. Transesophageal EUS-FNA of mediastinal lymph nodes provides minimally invasive tissue sampling, obviating the need for mediastinoscopy or bronchoscopy.
