A pancreaticoduodenectomy, pancreatoduodenectomy, Whipple procedure, or Kausch-Whipple procedure, is a major surgical operation involving the removal of the head of the pancreas, the duodenum including the duodenal papilla or ampulla of Vater, and the distal (lower) common bile duct. This operation is performed to treat cancerous tumours of the head of the pancreas, malignant tumors involving the common bile duct, duodenal papilla or ampulla of Vater, or duodenum near the pancreas, some precancerous lesions, some cases of pancreatitis with or without a definitive cause, and rarely, severe trauma.
