Digital single-operator peroral cholangioscopy-guided biopsy sampling versus ERCP-guided brushing for indeterminate biliary strictures: a prospective, randomized …
Background and Aims 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. Methods Patients with an indeterminate …
