| [ Summary ] | There are differences in the modes of extension for cholangiocarcinomas. The papillary type and the nodular expansive type primarily exhibit superficial expanding associated with mucosal cancer. In contrast, the nodular infiltrative type and the diffusely infiltrative type exhibit the charactistics of intramural expanding invasive cancer. Therefore, diagnosing the form of extension is very important to determine the type of curative surgery and other treatments. Because obstructive jaundice is often observed with cholangiocarcinomas in the hepatic portal region, bile duct drainage is usually necessary. In relation to the range of diagnosis of expanding cancer, diagnostic imaging, including ultrasound, shoud be performed before bile duct drainage to achieve an accurate diagnosis. | |
