Prospective evaluation of the optimal number of 25‐gauge needle passes for endoscopic ultrasound‐guided fine‐needle aspiration biopsy of solid pancreatic lesions in the absence of an onsite cytopathologist

Introduction:  A prior study with 22‐gauge needles recommended more than seven needle passes for endoscopic ultrasound‐guided fine‐needle aspiration biopsy (EUS‐FNA) of solid pancreatic lesions (SPL) without onsite cytopathology for optimal acquisition of cytopathological diagnosis. The feasibility of this recommendation should be re‐evaluated considering the later development and popularity of 25‐gauge EUS‐FNA needles. We aimed to determine the optimal number of needle passes for cytopathological specimen acquisition with 25‐gauge needles for EUS‐FNA of SPL.
