title: Bile duct cysts in adults.
abstract: BACKGROUND
  Bile duct cysts are rare and of uncertain origin. Most have been reported in young females of Asian descent, but an increasing number have occurred in Western adults.
  
  
  METHODS
  A Medline literature search was performed to locate articles on the pathophysiological concepts, clinical behaviour and management controversies pertaining to bile duct cysts in adults. Emphasis was placed on reports from the past two decades.
  
  
  CONCLUSIONS
  An increasing rate of occurrence of bile duct cyst is reported in adults. Type IV cysts are more frequent in adults than children. Presentation tends to be non-specific abdominal discomfort. Related hepatobiliary or pancreatic disease frequently precedes recognition, and may complicate the postoperative course. Surgical treatment aims to relieve complications deriving from the cysts and to reduce the significant risk of malignant change within the biliary tree. Complete cyst resection, cholecystectomy and Roux-en-Y hepaticojejunostomy reconstruction is standard. Controversy exists about the role of hepatic resection in type IV and V cysts, and the role of minimally invasive and laparoscopic treatment. In general, the outcome is good and a near-zero mortality rate has been reported in institutional series over the past decade.
