Diagnostic Efficacy of Liquid-Based Cytology in Endoscopic Ultrasound-Guided Fine Needle Aspiration for Pancreatic Mass Lesions During the Learning Curve A Retrospective Study

摘要

Objectives: The diagnostic yield of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) cytology widely varies depending on the treatment method used. Liquid-based cytology (LBC) has gained popularity in the gynecological field because of its efficacy in collection of target cells and simplicity in the manipulation of specimens. Since the introduction of EUS-FNA at our institution, we have used LBC for the diagnosis of pancreatic mass lesions. This study aims to investigate the diagnostic efficacy of EUS-FNA with LBC in patients with pancreatic mass lesions during the learning curve for EUS-FNA.
