Laparoscopy is often used to remove the gallbladder to treat gallstones or chronic inflammation of the gallbladder. This operation is called a laparoscopic cholecystectomy . If gallbladder cancer is found or suspected during that operation, surgeons usually convert the operation to an open cholecystectomy (removal of the gallbladder through a larger cut in the abdomen). The open method lets the surgeon see more and may lower the chance of releasing cancer cells into the abdomen when the gallbladder is removed. The use of the open procedure depends on the size of the cancer and whether surgery can remove all the cancer.
