Various surgical methods are applied in the treatment of pancreatic cancer. The most common among these is Whipple Surgery (Pancreaticoduodenectomy), which involves removing the head of the pancreas, the gallbladder, part of the stomach, a section of the small intestine, and nearby lymph nodes. For tumors in the body and tail of the pancreas, Distal Pancreatectomy is used, involving the removal of these parts. In more extensive cases, Total Pancreatectomy may be performed, requiring the removal of the entire pancreas, as well as parts of the stomach, a section of the small intestine, the bile duct, the gallbladder, and nearby lymph nodes.
