AAST Pancreas Injury Scale
AAST pancreas OIS (Moore 1990; widely cited 2018 trauma practice)Assigns AAST grade I–V for traumatic pancreatic injury based on contusion versus laceration, presence of duct injury, and whether the injury is distal, proximal (ampullary), or a massive head disruption.

How this tool works
Pancreatic trauma grading hinges on duct integrity and anatomic location relative to the superior mesenteric vein–portal vein axis. Low-grade (I–II) injuries spare the main pancreatic duct and are often managed non-operatively or with drainage alone. High-grade (III–V) injuries involve the duct: distal transection (III), proximal transection or ampullary/intrapancreatic bile-duct involvement (IV), and massive disruption of the pancreatic head (V). Multiphase CT suggests duct injury when lacerations are deep or transecting; MRCP or ERCP can confirm. Operative strategy ranges from distal pancreatectomy to complex pancreaticoduodenectomy or damage-control drainage.
