Objective: Endobronchial ultrasound-guided fine-needle aspiration (EBUS-FNA) cytology and EBUS-miniforceps biopsy (MFB) have emerged as less invasive tools for evaluating mediastinal lymph nodes and pulmonary lesions. The aim of this study is to compare the diagnostic yields of EBUS-FNA cytology to EBUS-MFB. Study Design: A retrospective cohort study was performed by reviewing the database at our institution between December 12, 2010, and August 10, 2012. A total of 476 consecutive cases were identified. Of these, 227 patients had concurrent FNA and MFB taken during the procedure. The results and diagnostic yields of both techniques are calculated. Results: Of the 476 cases, the mean age was 62 ± 14 years with 53% being males. In 453 of the total cases, the less invasive FNA technique alone produced enough diagnostic cytology material negating the need for concurrent MFB. Of these FNA cases, 280 were diagnosed as malignant neoplasms. The diagnostic yield of EBUS-FNA cytology was comparable to EBUS-MFB (95% FNA and 94% MFB). There were discordant diagnoses between cytology and histology in 19 of the 227 (∼8.4%) cases. Conclusions: EBUS-FNA cytology is a more efficacious diagnostic modality compared to EBUS-MFB.
