Diagnostic adequacy of FNA and FNB pancreatic lesions performed at St George Hospital

Abstract

Endoscopic ultrasound-fine needle aspiration (EUS-FNA) is the current primary technique for evaluating pancreatic lesions, with increasing use of fine needle biopsy (FNB) to obtain larger tissue sample. In this study, we aimed to determine the diagnostic yield of FNA and FNB of pancreatic lesions performed at St George Hospital in a two year period from 2020 to 2021 inclusive. There were 92 FNA and 69 FNB performed. The diagnostic yield of FNA was 86% and FNB was 87%. This result is in concordance to diagnostic yield ranges in published literature.
