Pancreatic Injury Grading

The pancreas is a relatively uncommon organ to be injured in trauma and many grading scales have been proposed


Classifications

American Association for Surgery in Trauma (AAST) 1

Wong et al. 

One method grading severity on CT in pancreatic injury proposed by Wong et al 3:

grade B
BI - deep laceration involving pancreatic tail
BII - complete transection of pancreatic tail
grade C
CI - deep laceration involving pancreatic head
CII - complete transection of pancreatic head
