Overview
- In the acute setting, pancreatic injuries may result in death due to associated vascular injuries.
- Delayed morbidity and mortality are usually caused by complications resulting from disruption of the pancreatic duct.
- Duct injury may lead to complications such as abscess, pancreatic pseudocyst, fistula, and pancreatitis.
Diagnosis
- Pancreatic injuries may be difficult to diagnose clinically.
Prognosis
- Although uncommon, early diagnosis is crucial, since delayed complications such as fistula, abscess, sepsis, and hemorrhage may lead to significant mortality, occurring in up to 20% of cases.
- Death due to delayed complications is usually due to sepsis and multiorgan failure.
Diagnostic Findings
CT
- Direct signs of pancreatic injury include pancreatic laceration, transection, and comminution. [1]
- Fluid collections, such as hematomas, pseudocysts, and abscesses, are often seen communicating with the pancreas at the site of fracture or transection.
- Focal enlargement of the pancreas and peripancreatic fluid are suggestive of pancreatic injury.
- Peripancreatic fat stranding, hemorrhage, and fluid between the splenic vein and pancreas are useful secondary signs.
