Dr Christian Gerges (Evangelisches Krankenhaus, DĂĽsseldorf, Germany) presented a prospective, multicentre, randomised controlled, post-market study showing that digital single-operator cholangioscopy (DSOC)-guided biopsies are safe and effective with a higher sensitivity compared with standard endoscopic retrograde cholangiopancreatography (ERCP) techniques in the visual and histopathological diagnosis of indeterminate biliary strictures [1].

Indeterminate biliary strictures remain a challenge to accurately diagnose, because they cannot be distinguished as malignant or benign despite initial ERCP and standard sampling methods. Biopsy under direct cholangioscopic vision might be superior to standard ERCP techniques such as brushing or biopsy. The aim of this study was to investigate whether DSOC improves the diagnostic yield in patients with indeterminate biliary strictures, compared with standar...
