Currently, there is no specific treatment for choledochal cysts. The main treatment method is laparoscopic surgery to remove the segment of the common bile duct containing the cyst, then re-establish biliary circulation by suturing the hepatic duct with the small intestine and duodenum. With this surgical method, after surgery, bile still circulates into the intestine to play the role of food digestion.

Laparoscopic choledochal cystectomy has become a routine technique in the treatment of choledochal cysts. This surgical procedure has shown its superiority and is gradually replacing intra-abdominal surgical methods in general and choledochal cyst surgery in particular. In addition, this method also combines the common hepatic duct-jejunal anastomosis technique.
