Accuracy of endoscopic ultrasound-guided fine needle biopsy for the diagnostic work-up of deep-seated lymphadenopathies and splenic lesions: an observational, retrospective, single-center experience

Aims Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is a less invasive approach for tissue acquisition of solid lesions when compared to surgical biopsy, and allows easier access to deep masses than external CT- or ultrasound-guided biopsy. Our aim was to establish the accuracy of EUS-FNB as a diagnostic tool for deep lymphadenopathies and splenic lesions.
