The liver is the most commonly injured abdominal organ after penetrating and blunt trauma1.
Blunt abdominal trauma-- most common cause of injuries, 95 % secondary to vehicle accidentOverall mortality from liver trauma 10-15%.Complex injuries who are actively bleeding have > 50% mortality (formidable challenge)

Blunt: Rapid deceleration
Rupture of Glissons capsuleParenchymal fracturesVenous and/or arterial bleeding, bile duct disruption, devitalized liver
Penetrating: Direct trauma
Minimal parenchymal disruption, venous and/or arterial bleeding, bile duct division
Devitalized liver rare

Major liver injury is still associated with a significant mortality rate Associated organ injuries and severity of the liver injury seem to be responsible for the majority of deaths in patients with major liver injuries

Main points in the management of severe liver injuries should include the rapid control of bleeding from the liver together with aggressive resuscitation, definitive surgical procedures, dealing with associated organ injuries and supportive post operative care
