Bile duct cysts, more common in females and Asia, can lead to malignancy, especially in adults. Early surgical excision and lifelong monitoring are crucial for managing these rare conditions.

Area of Science:

  • Hepatology
  • Gastroenterology
  • Surgical Oncology

Background:

  • Cystic diseases of the bile ducts are rare, predominantly affecting females and individuals in Asia.
  • Diagnosis often occurs in children, but adult cases, including during pregnancy, present diagnostic challenges due to cholelithiasis and pancreatic abnormalities.
  • Malignant transformation risk escalates with age, particularly in specific bile duct cyst types (Alonso-Lej Types I, IV, V), with intracystic lithiasis often linked to tumors.

Purpose of the Study:

  • To review the clinical presentation, diagnostic challenges, and management strategies for cystic diseases of the bile ducts.
  • To emphasize the risk of malignant transformation and its association with specific cyst types and intracystic lithiasis.
  • To highlight the importance of surgical intervention and long-term surveillance for patients with bile duct cysts.

Main Methods:

  • Literature review of cystic bile duct diseases, focusing on epidemiology, clinical features, and oncological outcomes.
  • Analysis of diagnostic complexities in adult and pregnant populations.
  • Evaluation of treatment approaches including surgical excision and monitoring protocols.

Main Results:

  • Bile duct cysts are more prevalent in females and Asian populations, with varied symptoms and diagnosis across age groups.
  • Adult diagnosis can be complicated by gallstones and pancreatitis; malignancy risk increases with age and is associated with specific cyst types.
  • Tumors, often intracystic, may be unresectable at diagnosis; malignant changes can occur even after cyst excision.

Conclusions:

  • Surgical excision of bile duct cysts is recommended at all ages, followed by vigilant long-term monitoring.
  • Malignancy should be highly suspected in all adult patients with bile duct cysts.
  • Hepatectomy or liver transplantation is the preferred treatment for Caroli's disease (Alonso-Lej Type V).
