Biochemical and radiological predictors of malignant biliary strictures

Abstract

A serum bilirubin level of 84 micromol/L or greater is the best predictor of MBS. Older age, proximal biliary dilatation, higher levels of bilirubin, alkaline phosphatase, ALT and AST are all associated with MBS. ERCP is necessary to diagnose and treat benign and malignant biliary strictures.
