Pancreatic Solid Lesions

This prospective, international, multicenter observational study aims to evaluate the role of Endoscopic Ultrasound-guided Detective Flow Imaging (EUS-DFI) in the characterization of solid pancreatic lesions. The study will assess microvascularization patterns identified by EUS-DFI and their association with the final diagnosis, using histopathology or clinical follow-up as the reference standard. Secondary objectives include evaluating interobserver agreement and the diagnostic accuracy of DFI vascular patterns for differentiating benign and malignant pancreatic lesions.

Purpose The primary objective of the study is to compare interpretation of EUS FNA/FNB samples for adequacy between ROSE and AI at bedside. To compare accuracy of preliminary diagnosis results between ROSE and AI at bedside versus final pathology report. Research design This is a prospective single center study to compare performance characteristics in the interpretation of EUS FNA/FNB samples between AI and ROSE. Procedures to be used Eligible patients will undergo EUS guided FNA/FNA of PSLs using standard of care. Sample slides are prepared by a cytopathologist at bedside and observed under a microscope. At the same time, the slides are scanned using a slide scanner and those images are saved for interpretation by AI at a later time.
