]> C24.0 Extrahepatic Bile Duct Note: In the 7th edition of the AJCC manual, Cystic Duct was removed from the Extrahepatic Bile Duct staging chapter and added to the Gallbladder staging chapter. For Collaborative Stage version 2, a new schema was created for Cystic Duct due to differences between schemas for bile ducts and gallbladder. &generalsize; CS Extension 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 of one of the stated extrahepatic organs or structures is classified as T3, and involvement of more than one extrahepatic structure is classified as T4. Note 3: Involvement within the porta hepatis is coded according to the structures involved: portal vein, common hepatic artery, and common hepatic duct.
