Surgical Techniques for Severe Liver Injury: A Comprehensive Review of Current Approaches and Advancements

ABSTRACT

In abdominal trauma, the liver is the most injured organ and treatment is usually determined by hemodynamics. Severe liver injury with extensive parenchymal injury and uncontrollable bleeding may rapidly evolve into the lethal triad of death (acidosis, hypothermia, and coagulopathy), requiring damage control surgery (DCS). Damage control resuscitation for trauma treatment reduces the need for DCS by enabling rapid control of massive bleeding. Thus, definitive surgery can be completed in one operation. Despite the systematic application of damage control resuscitation, definitive surgery cannot be achieved in severe, and extensive liver injuries. Therefore, understanding, and acquiring damage control surgical techniques is necessary to achieve DCS for severe liver injury. The Western Trauma Association and the World Society of Emergency Surgery have proposed algorithms for the nonoperative and operative management of blunt hepatic trauma. The algorithms list several surgical skills, including electrocautery or argon beam, manual compression, perihepatic packing, the Pringle maneuver, liver suture, omental packing, selective hepatic artery ligation, balloon tamponade, hepatic vascular isolation, and the shunt operation. These techniques require a multidisciplinary approach and individual honing of skills by the surgeon. Trauma surgeons, even hepatobiliary surgeons, must practice damage control techniques in severe liver injury models (animals or cadavers).
