Pancreatic injuries are relatively uncommon, but considerable morbidity and mortality may result if associated vascular and duodenal injuries are present or if the extent of the injury is underestimated and appropriate intervention is delayed. Optimal management includes the need for early diagnosis and accurate definition of the site and extent of injury. Prognosis is influenced by the cause and complexity of the pancreatic injury, the amount of blood lost, duration of shock, the rapidity of resuscitation and the quality and appropriateness of surgical intervention. Early mortality results from uncontrolled or major bleeding due to associated injuries while late mortality is generally a consequence of infection or multiple organ failure. Initial management of pancreatic trauma is similar to that of any patient with a severe abdominal injury. Stable patients with a suspected pancreatic injury should have non-invasive imaging including a CT scan or MRI. Urgent laparotomy is required in patients with evidence of major intraperitoneal bleeding, associated visceral trauma, or peritonitis. Operative intervention is guided by the integrity of the main pancreatic duct. External drainage is adequate for parenchymal injuries with an intact duct, while duct injuries of the neck, body and tail require a distal pancreatectomy. Pancreatic head injuries are more complex. If the duodenum is reparable and the ampulla is intact, external drainage suffices. Rarely, complex injuries may require a pancreatoduodenectomy after damage control surgery if the patient has multiple injuries and is unstable. Postoperative pancreatic complications including fistula and pseudocysts are common but can usually be treated endoscopically.
