PTH-041 Prospective study of the diagnostic yield from 20g FNB needle in routine upper GI and HPB lesions

Introduction

Improvements in the EUS FNA and FNB needle design and optimisation of tissue acquisition techniques have resulted in better diagnostic yield (DY). In addition, recently there has been considerable interest in histological processing of tissue acquired using newer ‘core’ FNA needles. At BSG 2016 we provided preliminary data on DY of tissue acquired using standard FNA needle. We hereby present data on yield of 20G Cook...
