Heparin priming of EUS-FNA needles does not adversely affect tissue cytology or immunohistochemical staining

Abstract

Background and study aims  Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) or biopsy (FNB) is an indispensable diagnostic tool. Improvements in needling technique have led to increasing tissue yields.
