Liver transplantation consequential to Caroli's syndrome: a case report.

Caroli's disease is a rare condition that includes fibrocystic malformations of the bile duct. It consists of multifocal congenital dilatations of the intrahepatic bile ducts, which may be diffuse or limited, presenting in sack form that produces cystic structures which communicate with the biliary tree. Herein we have presented the case of a 44-year-old woman with recurrent cholangitis consequential to Caroli's syndrome. The distinctive feature of this case was that it was the first and only liver transplantation performed to date for this cause at our center among 700 procedures that had been performed over 19 years. The hepatectomy sample from the liver transplantation showed large cystic dilatations at the level of segments VII and VIII. The pathological study reported congenital dilatation of the intrahepatic bile ducts, associated with congenital hepatic fibrosis (Caroli's syndrome). Caroli's syndrome is a complex association of conditions which usually presents together with polycystic kidney lesions. Orthotopic liver transplantation is still the only therapeutic option for diffuse, uncontrollable cases or those with significant portal hypertension, as well as being the final option in the other cases in the event of a lack of response to other therapeutic options or as an alternative to them.
