Gallbladder cancer may be treated with a cholecystectomy, surgery to remove the gallbladder and some of the tissues around it. Nearby lymph nodes may be removed.

Unresectable gallbladder cancer is defined by the following TNM classification:
 
* Any T, N1, M0
* Any T, N0 or N1, M1
* Most T3, N0, M0
* T4, N0, M0
 
These patients are not curable. Significant symptomatic benefit can often be achieved with relief of biliary obstruction. A few patients have very slow-growing tumors and may live several years.


Surgical biliary bypass: If the tumor is blocking the small intestine and bile is building 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.
Endoscopic stent placement: If the tumor is blocking the bile duct, surgery may be done to put in a stent (a thin, flexible tube) to drain bile that has built up in the area. The stent may be placed through a catheter that drains to the outside of the body or the stent may go around the blocked area and drain the bile into the small intestine.
Percutaneous transhepatic biliary drainage: A procedure done to drain bile when there is a blockage and endoscopic stent placement is not possible. An x-ray of the liver and bile ducts is done to locate the blockage. Images made by ultrasound are used to guide placement of a stent, which is left in the liver to drain bile into the small intestine or a collection bag outside the body. This procedure may be done to relieve jaundice before surgery.

Overview

Surgery

Gallbladder cancer may be treated with a cholecystectomy, surgery to remove the gallbladder and some of the tissues around it. Nearby lymph nodes may be removed. A laparoscope is sometimes used to guide gallbladder surgery. The laparoscope is attached to a video camera and inserted through an incision (port) in the abdomen. Surgical instruments are inserted through other ports to perform the surgery. Because there is a risk that gallbladder cancer cells may spread to these ports, tissue surrounding the port sites may also be removed.

If the cancer has spread and cannot be removed, the following types of palliative surgery may relieve symptoms:

Surgical biliary bypass: If the tumor is blocking the small intestine and bile is building 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. Endoscopic stent placement: If the tumor is blocking the bile duct, surgery may be done to put in a stent (a thin, flexible tube) to drain bile that has built up in the area. The stent may be placed through a catheter that drains to the outside of the body or the stent may go around the blocked area and drain the bile into the small intestine. Percutaneous transhepatic biliary drainage: A procedure done to drain bile when there is a blockage and endoscopic stent placement is not possible. An x-ray of the liver and bile ducts is done to locate the blockage. Images made by ultrasound are used to guide placement of a stent, which is left in the liver to drain bile into the small intestine or a collection bag outside the body. This procedure may be done to relieve jaundice before surgery.
