Objective: The purpose of this study was to compare the performance of the monolayer preparation (Cyto Lyt or Thin prep) to the routine use of Papanicolau methods on the analysis of specimens obtained using EUS-FNA.

Introduction: The presence of a pathologist during an endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is often a luxury. In addition, preparation of multiple slides for a fine needle aspiration can be time-consuming for the gastroenterologist who waits for verbal feedback on the adequacy of the specimen. Often, a timely diagnosis is needed to direct patient management. Currently, there is no established standard of care for EUS-FNA preparation. A liquid based cytologic fixative preparation (Thin-prep or CytoLyt), is a well-established process used by pathologists for evaluating cervical smears. It has not yet been adopted or accepted for EUS-FNA. This method combines multiple aspirates on a single slide, thereby decreasing the number of slides that need to be processed and interpreted by the pathologist
