胆管癌临床诊断常较困难,近年来胆道内超声(IDUS)的应用逐渐增多,不会有因与肠内气体重叠使中下段和乳头部胆管癌显示图像不佳的情况,对原发性胆管癌确诊率达100%。磁共振胰胆管造影(MRCP)为无创检查,可以三维图像显示胆管树和肿瘤的部位、大小及浸润范围,同时显示梗阻段胆管上下情况。近年来,研究发现胆管癌发病与黏蛋白基因、三叶肽基因和同源异型盒基因的异常表达有关。
Clinical diagnosis of cholangiocarcinoma is often more difficult. In recent years, the application of intraductal ultrasound (IDUS) has gradually increased. There will be no overlap between the gas in the intestine and the poor image of the bile duct in the middle and lower papilla. Cancer diagnosis rate of 100%. Magnetic resonance cholangiopancreatography (MRCP) is a non-invasive examination that shows the location, size, and extent of infiltration of the biliary tree and tumor in a three-dimensional image and shows the bile duct up and down in the obstruction section. In recent years, the study found that the incidence of cholangiocarcinoma and mucin gene, trefoil peptide gene and homeobox gene abnormal expression.
