Abstract

Background There has been a paradigm shift in tertiary centers from endoscopic ultrasound (EUS) fine-needle aspiration to EUS fine-needle biopsy (EUS-FNB) for tissue acquisition in solid lesions. While data exists on the use of FNB needles in solid pancreatic lesions, very few studies looked at the utility of FNB in solid extrapancreatic lesions. Our aim was to study and compare the technical success and feasibility of EUS-FNB in evaluating solid pancreatic and extrapancreatic lesions using a novel FNB needle. Methods We performed a retrospective cohort study of patients with solid masses or lesions needing EUS-guided core biopsy at the University of Utah between May 2016 and November 2017. All core biopsies were obtained using an Acquire™ Fine Needle Biopsy Device (Boston Scientific Corporation, Natick MA, USA). Rapid on-site evaluation was performed by a board-certified cytopathologist in all cases. Results One hundred thirty-two patients (87 male) were included. Ninety-nine (73.3%) of the lesions were located in the pancreas. All needle sizes (19 G, 22 G and 25 G) had similar yield. The mean number of passes needed was 2.28±0.7. EUS-FNB of the pancreatic lesions had a diagnostic accuracy of 97.9%, comparable to the 97.2% for the biopsied extra-pancreatic lesions. Only 3 of 132 cases needed re-biopsy at a later date. No immediate adverse events were reported. Conclusion In this large, single-center study, EUS-FNB with a novel Franseen-design needle was proven to be an effective modality for tissue acquisition from both pancreatic and extrapancreatic solid lesions.
