Usefulness of combined endobronchial and endoscopic ultrasound-guided needle aspiration in the diagnosis of sarcoidosis: a prospective, multicenter trial

Abstract

organs confirmed by a cyto-or histopathological examination. 2,3,4 Because granulomatous inflammation can be observed in many other diseases with similar clinical and / or radiological features (ie, tuberculosis, mycobacterial or fungal infections, pneumoconiosis, hypersensitivity pneumonia, lymphoma, lung cancer, berylliosis, and also sarcoid reaction, which may accompany or precede IntroductIon Sarcoidosis is a chronic inflammatory disease of unknown etiology. Noncaseating granulomas in various organs, with predilection for mediastinal and hilar lymph nodes and lungs, are characteristic of this disease. 1,2The diagnosis of sarcoidosis is based on a combination of clinical outcome, radiology findings, and presence of noncaseating granulomas in involved

A Randomized Comparison of Sample Adequacy and Diagnostic Yield of Various Suction Pressures in EBUS-TBNA

“…Similarly, the station of the mediastinal lymph node sampled also has a bearing on the diagnostic yield. A recent study found a positive association between sampling of subcarinal lymph nodes and yield of endosonographic biopsy [19]. This is probably due to ease of sampling this station of lymph nodes.…”
