A Type 2 choledochal cyst is characterized by a cystic dilation of the common bile duct, and the most effective treatment is to excise the cyst. This approach is essential because simply draining the cyst or not addressing the underlying pathology may lead to complications such as cholangitis, pancreatitis, or carcinoma due to the risk of biliary stasis and inflammation over time.

In excising the cyst, the surgical procedure typically involves removing the cyst and reconstructing the bile duct, which can help prevent future complications and ensure proper bile flow. This treatment also addresses any potential risk for malignancy associated with the cyst by removing the affected area completely.

Other options, such as liver resection, may not be necessary or beneficial in the context of a Type 2 choledochal cyst. Similarly, transduodenal excision or Roux-en-Y hepaticojejunostomy are more appropriate in different scenarios involving other types of cysts or more complex anatomical considerations, but not specifically indicated for a Type 2 choledochal cyst. Therefore, excising the cyst directly addresses the underlying issue and is the most effective management strategy.
