Hepatic duct tumors may occur in the intrahepatic bile ducts or extrahepatic bile ducts, with malignant tumors being the most common. Intrahepatic bile duct tumor, also known as cholangiocellular hepatocellular carcinoma, is a kind of primary liver cancer, and the treatment should be carried out according to the principle of primary liver cancer. In principle, surgical treatment should be considered for cholangiocellular hepatocellular carcinoma, either radical hepatectomy or palliative surgery such as regular segmental or lobectomy. Other treatment modalities include transhepatic artery embolization chemotherapy, radiofrequency ablation, targeted drug therapy, and traditional Chinese medicine (TCM), which can be used as an adjuvant means of postoperative treatment as well as for treating patients who are unable to undergo surgery. The most common extrahepatic bile duct tumor is cholangiocarcinoma, and clinically, different surgical methods need to be selected according to the specific location of cholangiocarcinoma. Hepatoportal cholangiocarcinoma radical surgery should be chosen for high-grade cholangiocarcinoma, middle cholangiocarcinoma can be resected as a single lesion, i.e. cholangiocarcinoma radical surgery, while pancreaticoduodenectomy should be chosen for lower cholangiocarcinoma. Regardless of the surgical approach, care should be taken to give skeletonization of the hepatoduodenal ligament. Jaundice can also be relieved by external drainage via PTCD or endoscopic placement of a stent for internal drainage in patients who cannot undergo surgery.
