Abstract
Accurately diagnosing indeterminate biliary strictures is challenging but important
for patient prognostication and further management. Biopsy sampling under direct cholangioscopic
vision might be superior to standard ERCP techniques such as brushing or biopsy sampling.
Our aim was to investigate whether digital single-operator cholangioscopy (DSOC) compared
with standard ERCP workup improves the diagnostic yield in patients with indeterminate
biliary strictures.
