Why is the common bile duct cyst removed?

Question
Hello doctor,
My husband has just been treated for a common bile duct cyst, now his health is fine. During the treatment at the provincial hospital, the doctor operated on her husband only to remove the gallbladder and perform a cholecystectomy, not the cyst in the bile duct. Her family had to transfer her husband to another hospital for re-operation and removal of the common bile duct cyst. So let me ask why the common bile duct cyst should be removed? Thank you doctor.

Hello,
To the question: “Why is the common bile duct cyst removed?” The doctor would like to answer as follows:
Common bile duct cyst is a congenital disease, treatment requires removal of the cyst to avoid infection and the risk of cancer. Surgery of choice is cholecystectomy and choledochal cystectomy, Roux-en-Y biliary anastomosis. Surgery to connect the cystic duct of the common bile duct to the gastrointestinal tract was still performed in the past, but now it is almost no longer applied.
The connection of the common bile duct cyst to the gastrointestinal tract is decided by the surgeon, depending on the patient's condition, the surgeon's experience and the specific situation during surgery.
If you still have doubts about the effective treatment of common bile duct cysts, you can go to the hospital of Vinmec Health System for examination and clear advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
