Diagnosis of pancreas injury is not easy at first consult. It's a retrospective study, in children under 15 years and 3months, between January 1st 2010 to August 31th 2019, to prove that the first level of lipase is correlated with the severity of pancreatic injury.

Every children with elevated serum lipase after trauma during those years will be selected.

The children with pancreatic tumors will be excluded. American Association of Surgeon Trauma (AAST) classification of pancreas injury will be used to grade severity.

Children will be divided in two groups : one including pancreatic lesion with duct injury and one without duct injury.

Data will include mechanism of injury, associated injury, length of stay, maximal lipase level, nutritional care and local complications will be noted.

The main objective of this study is to determine if there is a correlation between the initial serum lipase and the severity of the pancreatic injury.

Inclusion Criteria:

• Children under 15 years 3 months with elevated lipase serum level after trauma.

Exclusion Criteria:

• Elevation of lipase secondary to pancreatic tumor

Children under 15 years 3 months with elevated lipase serum level after trauma will be included.
