Overview of extrahepatic cholangiocarcinoma: refers to the special primary in the pan ampulla, common bile duct, the total liver camps, left and right at the intersection of Bf tube, gallbladder left hepatic duct common malignant liver tumor officials, generally refers to the hepatic duct extrahepatic bile duct cancer . The common bile duct cancer or ampullary cancer clinical manifestations and treatment of pancreatic cancer is basically the same, often classified as periampullary cancer. The incidence of extrahepatic cholangiocarcinoma no precise statistics, but in malignant tumors accounted for 3% -6% incidence of biliary tract cancer, the incidence of extrahepatic cholangiocarcinoma higher than gallbladder, extrahepatic bile duct cancer and the incidence of than in Western countries; early as 1977, Les-lie, once the autopsy report the detection of cholangiocarcinoma 0.01% -0.46% rate.
Bile duct of unknown etiology. Gallstones, bile duct infection or cholestasis nothing like the occurrence of cholangiocarcinoma, bile duct cancer bile duct stones in patients with companions only about 25% of all patients. It was suggested that the following diseases are more prone to bile duct cancer patients: Chronic ulcerative colitis, congenital hepatic fibrosis, liver Chinese sinensis infection.
Overview of extrahepatic bile duct cancer is generally believed that, in the bile duct in autopsy about 0.2%, domestic 38 College autopsy of 1979 patients with malignant tumor were analyzed and found that the detection rate of extrahepatic cholangiocarcinoma 0.07%; LosAngeles National Hospital autopsy data analysis shows that cholangiocarcinoma can occur in different parts of the bile duct, about 40% occurred in the proximal bile duct, 30% occurred in the cystic duct and hepatic duct junction, 25% occurred in the hepatic duct, 5% occurred in the cystic duct. 1229 cases of domestic literature occurred in parts of extrahepatic cholangiocarcinoma were analyzed, the result is 39% of total bile duct, hepatic duct carcinoma accounts for 20% of the bifurcation of hepatic duct cancer is about 30%, left and right hepatic duct carcinoma accounts for 6 %, 5% of cystic duct carcinoma. Third Military Medical University Hospital on 47 cases treated in 1954-1979 in extrahepatic bile duct cancer, and found 30 cases in the hepatic portal, accounting for 63.8%. And Leslie reported that compared to the location and occurrence of cholangiocarcinoma in Western countries, basically the same. Its rate of operation at home and abroad have found differences between scholars in the 1112 cases of biliary tract surgery in 28 patients with extrahepatic cholangiocarcinoma found, surgical detection rate was 2.5%; foreign reports of bile duct surgery was 0.5%. And gallbladder cancer incidence on the contrary, more men than women extrahepatic bile duct, the ratio of the two 1.5-3:1, the majority considered that the ratio of male and female incidence of 2: l. The age of onset of extrahepatic cholangiocarcinoma at home and abroad agreed that the multiple of 40 years of age, half of its more than 60 years of age, suggesting that the extrahepatic bile duct in the elderly is not uncommon.
These are outlined in an overview of the extrahepatic bile duct cancer.
