Core Tip

Core Tip: Endoscopic management of patients with primary sclerosing cholangitis (PSC) is complex; our study is the first to evaluate the utility of single-operator video cholangioscopy (SOVC) with digital imaging quality in these patients. Our data indicate that the use of digital SOVC in PSC patients substantially improves the evaluation of biliary strictures and that SOVC effectively supports interventions, such as stricture dilation and biliary stone treatment, in PSC patients; mild to moderate complications occurred in a minority of cases. Concluding digital SOVC may be effective and safe as an additive tool for the complex endoscopic management of PSC patients.
