Two types of standard treatment are used:
The following types of surgery are used to treat extrahepatic bile duct cancer:
Removal of the bile duct
If the tumor is small and only in the bile duct, the entire bile duct may be removed. A new duct is made by connecting the duct openings in the liver to the intestine. Lymph nodes are removed and viewed under a microscope to see if they contain cancer.
Removal of the part of the liver where cancer is found. The part removed may be a wedge of tissue, an entire lobe, or a larger part of the liver, along with some normal tissue around it.
A surgical procedure in which the head of the pancreas, the gallbladder, part of the stomach, part of the small intestine, and the bile duct are removed. Enough of the pancreas is left to make digestive juices and insulin.
Surgical biliary bypass
If the tumor cannot be removed but is blocking the small intestine and causing bile to build up in the gallbladder, a biliary bypass may be done. During this operation, the gallbladder or bile duct will be cut and sewn to the small intestine to create a new pathway around the blocked area. This procedure helps to relieve jaundice caused by the build-up of bile.
If the tumor is blocking the bile duct, a stent (a thin tube) may be placed in the duct to drain bile that has built up in the area. The stent may drain to the outside of the body or it may go around the blocked area and drain the bile into the small intestine. The doctor may place the stent during surgery or PTC, or with an endoscope.
Radiation therapy is a cancer treatment that uses high-energy x-rays or other types of radiation to kill cancer cells or keep them from growing. There are two types of radiation therapy. External radiation therapy uses a machine outside the body to send radiation toward the cancer. Internal radiation therapy uses a radioactive substance sealed in needles, seeds, wires, or catheters that are placed directly into or near the cancer. The way the radiation therapy is given depends on the type and stage of the cancer being treated.
