We report the case of a 31-year-old male patient with a diffuse form o
f Caroli's disease presenting as recurring bouts of biliary pancreatit
is. Following sphincterotomy, the patient remained asymptomatic for 5
years. He then developed acute cholangitis and, at laparotomy, all sup
erficial liver cysts were fenestrated in order to remove intrahepatic
bile duct calculi. A right hepatectomy, removing the most severely aff
ected liver parenchyma was not considered feasible because of the smal
l size of the left lobe and the existence of an associated congenital
hepatic fibrosis. In diffuse forms of Caroli's disease biliary drainag
e techniques have often proved ineffective in preventing recurring bou
ts of cholangitis. Moreover, liver resection is seldom feasible becaus
e of associated congenital hepatic fibrosis. In this setting, liver tr
ansplantation may represent the only effective and durable form of tre
atment.
