Sa1477 POSITIVE PREDICTIVE VALUE OF MAIN PANCREATIC DUCT DILATION FOR MALIGNANCY PREDICTION IN SOLID PANCREATIC MASSES: A SINGLE-CENTER RETROSPECTIVE ANALYSIS

Abstract:

Aim we aimed to evaluate the diagnostic association between main pancreatic duct (MPD) dilation and malignancy occurrence in pancreatic solid lesions during endoscopic ultrasound (EUS) evaluation. Methods observational, analytic, historic cohort. Retrospective data from patients with solid hypoechoic pancreatic lesions evaluated via EUS from Jan/2016 to Dec/2018 was prospectively analyzed. The MPD diameter were measured in all patients. All solid lesions were punctured via fine-needle aspiration for further histological analysis. Malignancy was defined in accordance with histological, surgical specimen and/or 6-months follow up. MPD diameter cut-off value for malignancy was estimated using Youden’s index. A sub-analysis was built in accordance with lesion localization. MPD diameter, EUS and EUS-guided fine-needle aspiration biopsy for determining sensitivity, specificity, positive and negative …
