Which operation is most commonly performed to treat pancreatic cancer?

• A. Distal pancreatectomy
• B. Pylorus-sparing pancreatoduodenectomy
• C. Whipple procedure
• D. Total pancreatectomy

Answer: (C)

When pancreatic cancer is operable, the tumor’s location guides the operation. Most pancreatic cancers arise in the head of the pancreas, so removing that portion and enabling reconstruction of the digestive tract is the standard surgical approach. This operation, pancreaticoduodenectomy, commonly known as the Whipple procedure, entails removing the pancreatic head along with the duodenum, a portion of the stomach (or pylorus, depending on the variant), gallbladder, and common bile duct, followed by reconstructing the pancreatic, biliary, and gastric connections. This approach targets the tumor with clear margins and often includes regional lymph node removal, which is why it’s favored for head-side cancers. In contrast, a distal pancreatectomy targets tumors in the body or tail and would not address a head lesion. A total pancreatectomy removes all pancreatic tissue and leads to complete loss of pancreatic function, which carries significant metabolic consequences and is reserved for more extensive disease. A pylorus-sparing pancreatoduodenectomy is a variant of the same overall operation aimed at preserving the pylorus, but it is not the broader standard practiced for the majority of pancreatic head cancers. Therefore, the Whipple procedure best explains why this operation is the most commonly performed surgical treatment for pancreatic cancer.
