title: Bile duct cyst type V (Caroli's disease): surgical strategy and results.
abstract: BACKGROUND
  Caroli's disease (CD) is a benign congenital disorder characterized by segmental cystic dilatation of the intrahepatic biliary ducts. Therapeutic strategy includes medical treatment, percutaneous, endoscopic or surgical drainage of the affected bile ducts, liver resection or transplantation. The aim of this study was to analyse the results and long-term follow-up of a consecutive series of patients who underwent surgical treatment for CD.
  
  
  METHODS
  Between 1995 and 2005, 10 patients were surgically treated for CD. Variables evaluated were: age, gender, clinical presentation, diagnostic procedures, percutaneous and surgical treatments, histopathological analysis and outcome.
  
  
  RESULTS
  The average age of the patients was 45.8 years. Recurrent cholangitis was the main clinical manifestation (70%). In unilateral CD a liver resection was performed in nine patients (left lateral sectionectomy in seven, left hepatectomy in one and right hepatectomy in one). In bilateral disease a cholecystectomy, duct exploration, hepaticojejunostomy and liver biopsy of both lobes were performed. Average follow-up was 60 months. All the patients are alive and free of symptoms without recurrence in the remnant liver.
  
  
  CONCLUSIONS
  Liver resection is the preferred therapeutic option for unilateral CD, demonstrating good results in long-term follow-up. In bilateral disease, hepaticojejunostomy could be considered as an alternative or a previous step to liver transplantation, which still remains the ultimate option.
