Pearls and Pitfalls
With sclerosing cholangitis, strictures involve the extrahepatic bile ducts exclusively in 10% of patients, solely the intrahepatic bile ducts in 15%, and both intrahepatic and extrahepatic bile ducts in 75%.
Cholangiocarcinoma (CCA) develops in 8–18% of patients with primary sclerosing cholangitis (PSC); the diagnosis of CCA is made concurrently with that of PSC in 40–60% of patients.
The diagnosis of CCA in the presence of PSC is notoriously difficult; biliary brushings and cytology have a sensitivity of less than 40%.
Repeated endoscopic therapy of dominant strictures may delay the diagnosis of CCA and affect survival adversely.
Operative resection of dominant extrahepatic strictures may prevent development of CCA, prolong survival, and delay need for liver transplantation.
Once cirrhosis develops, liver transplantation is the optimal therapy for patients with PSC; outcomes are equivalent to, or better than, those of transplantation for other indications.
