543 Is vascularity enough to pbkp_redict neoplasia in bile duct lesions during peroral cholangioscopy?

Abstract:

Aim to evaluate the role of neovasculature in bile duct lesions for the pbkp_rediction of neoplasia during peroral cholangioscopy. Methods a cohort study with prospectively collected endoscopic data of patients with bile duct lesions evaluated via POCS who were aged≥ 18 years. Patients with lesions but with no subsequent histological confirmation, with less than 6 months of follow-up, or concomitant choledocholithiasis during POCS were excluded for analysis. POCS were performed using a digital, single-operator cholangioscopy system (Spyglass®, Boston Scientific, Marlborough, MA, USA). Neovasculature was defined as the presence of irregular or spider vascularity on bile duct lesions. The neovasculature overall diagnostic accuracy was estimated considering a 6 months follow-up as a gold standard. Inter-observer agreement analysis was performed between two endoscopists (JO & JAV). A p-value< 0.05 was …
