This input is used for staging
Notes
**Note 1:** The cystic duct extends from the neck of the gallbladder to its junction with the common hepatic duct, to form the common bile duct. **Note 2:** Involvement within the porta hepatis is coded according to the structures involved: portal vein, common hepatic artery, and common hepatic duct.Default
