In memoriam: Fine‐needle aspiration, birth: Fine‐needle biopsy: The changing trend in endoscopic ultrasound‐guided tissue acquisition

Background and Aim Fine‐needle aspiration (FNA) cytology has been the preferred technique for procuring tissue at endoscopic ultrasound (EUS) procedures for the past 25 years. To overcome some of the limitations of FNA cytology, fine‐needle biopsy (FNB) has been recently developed to yield histological tissue. Main objective was to compare the diagnostic yield of FNB compared to FNA for both onsite and offsite specimen assessment. Methods A...
