Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the minimally invasive diagnostic modality for the evaluation of mediastinal and hilar lymph nodes (LNs). Traditionally, EBUS-TBNA is performed using either 21 gauge (G) or 22 G needle with a major limitation of inadequate sample especially when histologic assessment of tissue architecture is necessary such as in lympho-proliferative disorders and granulomatous inflammation. Although the specimen obtained with larger bore 19 G needle has been shown to be superior in terms of more cellular material and ability to subclassify malignant disease, it has more bloody samples. Recently a novel 22 G fine needle biopsy device (EBUS-FNB) has been introduced for endobronchial use after an experience gained from gastroenterology endoscopic ultrasound reporting high yield for core biopsies. FNB device has a unique design with 3 symmetrical, fully formed, cutting heels with 3 angled points to provide acquisition of FNB specimen in the form of a core tissue which might improve the overall diagnostic yield. Herein, investigators will study the diagnostic yield and safety of the 22 G EBUS-FNB needle with 19 G EBUS needle in the evaluation of mediastinal and hilar lymphadenopathy.
