Abstract

The evaluation of indeterminate biliary strictures (IS) remains a diagnostic challenge. Current investigative techniques include cytology brushing, intraductal biopsy, fluorescent in-situ hybridization (FISH), direct cholangioscopy visualization, and probe-based confocal endomicroscopy (pCLE). The aim of our study was to perform a cost-utility analysis comparing these various techniques during endoscopic retrograde cholangiopancreatography (ERCP).
