CRP and cholangitis: In the 1st Delphi survey, eight elements were identified as defining cholangitis and were pooled in two groups: (A) clinical elements—fever without extrahepatic source and/or shivering, stool color change, new/increasing jaundice, abdominal discomfort (vomiting, poor feeding, and irritability); (B) laboratory and imaging elements—inflammatory response (WBCs and/or CRP and/or PCT), increased/increasing transaminases, increased/increasing GGT and/or bilirubin, and bile lakes.
