The Whipple procedure is the most common operation used to treat pancreatic cancer. It involves removing the head of the pancreas, part of your small intestine (bowel), gall bladder and part of the bile duct. Sometimes part of the stomach also has to be removed. The end of the bile duct and the remaining part of the pancreas is then connected to the small intestine.
