There are 2 general types of surgery for bile duct cancer: potentially curative surgery (for resectable cancer) and palliative surgery (for unresectable cancer).

Potentially curative surgery for bile duct cancer

Resectable (potentially curative surgery) means imaging tests or the results of earlier surgeries show there’s a good chance the surgeon can remove all the cancer along with a rim (margin) of healthy tissue around it. This decision is based on the location of the tumor, it’s size and the extent of its spread. Only a small percentage of bile duct cancers are resectable when they're first found.

If potentially curative surgery is being considered, you may want to get a second opinion or even be referred to a large cancer center. Nearly all doctors agree that surgery offers the only realistic chance for curing people with bile duct cancer. But there are differences of opinion about how advanced a bile duct cancer can be and still be treatable with surgery. The surgery needed for bile duct cancer is often complex and requires an experienced surgeon. These operations are most often done at major cancer centers.

If a tumor is unresectable, it means doctors think the cancer is too advanced, it has spread too far, or is in too difficult a place to be entirely removed by surgery.

Laparoscopy to plan bile duct surgery

If your surgical team is planning curative surgery, they first may do a laparoscopy (a type of minor surgery) to look for any spread of the cancer that could make curative surgery not an option. This procedure is described in Tests for Bile Duct Cancer. During the laparoscopy, the surgeon can look for areas of cancer that did not show up on imaging tests. If the cancer is resectable, laparoscopy can also help plan the operation to remove it.

Surgery to remove bile duct cancer can have serious side effects. Depending on how extensive it is, you may need many weeks to recover. It’s very important to understand how the surgery is likely to affect your quality of life.

Surgery for resectable bile duct cancers

For resectable cancers, the type of operation depends on where the cancer is.

• Intrahepatic bile duct cancers are in bile ducts that are inside the liver. To treat these cancers, the surgeon cuts out the part of the liver containing the cancer. Removing part of the liver is called a partial hepatectomy. Sometimes this means a whole lobe (right or left part) of the liver must be removed. This is called hepatic lobectomy. It is a complicated operation that requires an experienced surgical team. If the amount of liver removed is not too great, the liver will still work normally because it has some ability to grow back.
• Perihilar bile duct cancer develops where the branches of the bile ducts first leave the liver. Surgery for these cancers is complicated and requires great skill. Usually, part of the liver is removed along with the bile duct, gallbladder, nearby lymph nodes, and sometimes part of the pancreas and small intestine. Then the surgeon connects the remaining ducts to the small intestine. This is a complex operation that can lead to life-threatening complications for some people.
• Distal bile duct cancers are further down the bile duct near the pancreas and small intestine. Along with the bile duct and nearby lymph nodes, the surgeon often has to remove part of the pancreas and small intestine. This operation is called a Whipple procedure. Like the other operations, this is a complex procedure that requires an experienced surgical team.

Palliative surgery for bile duct cancer

Palliative surgery is done to relieve symptoms or treat (or even prevent) complications, such as blockage of the bile ducts. This type of surgery is done when the cancer is too widespread to be removed completely. Palliative surgery is not expected to cure the cancer, but it can sometimes help a person feel better and sometimes can even help them live longer.

In some cases, the doctor might think the cancer is resectable (can be removed)  based on the information available (imaging tests, laparoscopy, etc.), but once surgery starts it becomes clear that the cancer is too advanced to be removed completely. In these cases, the surgeon might still try to prevent or relieve symptoms using a different approach.

Biliary bypass

The surgeon creates a bypass around the tumor blocking the bile duct by connecting part of the bile duct before the blockage with a part of the duct that lies past the blockage. The bile duct may also be connected to the intestine itself. Often, the gallbladder is used to provide some of the bypass. Different types of biliary bypass operations may be done, based on where the blockage is. The bypass allows the bile to flow into the intestines and can help reduce symptoms such as jaundice or itching.

Stent placement

If a bypass can’t be done, the surgeon may put a plastic or expandable metal tube (called a stent) inside the bile duct to keep it open and allow bile to flow. This may be done during an endoscopic retrograde cholangiopancreatography procedure (ERCP) or during a procedure similar to percutaneous transhepatic cholangiography (PTC).

These procedures can relieve side effects. As a result, after these procedures patients often experience long periods when all symptoms disappear and their quality of life improves.

Palliative surgery is described in more detail in Palliative Therapy for Bile Duct Cancer.

Possible risks and side effects of bile duct surgery

The risks and side effects of surgery depend on the extent of the operation and a person’s overall health before surgery. Another key factor is how well the liver is working. All surgery carries some risk, including the possibility of bleeding, blood clots, infections, complications from anesthesia, pneumonia, and even death in rare cases.

People will have some pain from the incision after surgery, but this can usually be controlled with medicines.

Surgery for bile duct cancer is a major operation that might mean removing parts of other organs. This can have a major effect on a person’s recovery and health after the surgery. Serious problems soon after surgery can include bile leakage into the abdomen, infections, and liver failure. Because most of the organs removed are involved in digestion, eating and nutrition problems may be a concern after surgery.
