OBJECTIVE: To review the outcome of a consecutive number of patients with
primary sclerosing cholangitis (PSC) treated at one institution to define
prognostic variables and determine the influence of surgery on outcome.
DESIGN: Case series of patients with PSC seen in Cape Town, South Africa,
between 1981 and 1991. SETTING: Tertiary referral center. PATIENTS:
Thirty-six patients with PSC were studied. Diagnosis was based on
cholangiographic findings of multiple strictures of the bile ducts together
with compatible clinical and biochemical features. Thirty-two patients were
followed up prospectively for up to 9 years. MAIN OUTCOME MEASURES: Patient
outcome was defined as good (stable or slowly progressive disease) or poor
(death or liver transplantation). RESULTS: During the follow-up period,
seven patients with PSC died and two underwent liver transplantation.
Actuarial survival at 5 years was 52%. An increased serum bilirubin
concentration was the only variable at presentation that independently
predicted a poor outcome. Cholangiography was unhelpful in predicting
patient outcome. Six patients who developed obstructive jaundice associated
with advanced liver disease underwent biliary drainage operations for
surgically correctable strictures, but this did not seem to prevent
progression of the disease. Two patients who progressed to end-stage liver
disease went on to have liver transplantation and were alive with
functioning grafts at 7 and 14 months, respectively. CONCLUSIONS:
Symptomatic PSC is a progressive disorder with a poor prognosis. Our
experience suggests that patients with advanced liver disease caused by PSC
should be considered directly for liver transplantation rather than biliary
bypass operations.
