Liver is the second most common solid organ frequently injured by blunt trauma and could be the commonest organ injured by penetrating trauma. The injury can be mild and goes undetected or detected and treated conservatively. It can be severe where the liver wounds can bleed until death. Once the patients with liver injury are resuscitated, the degree of liver injury can be evaluated using ultrasound scan and computed tomography imaging. If the patient is stable, diagnostic peritoneal lavage is very helpful when the imaging facilities are not available. Non-operative treatment of liver trauma has been proven to be valuable in 80% of patients with grade I, II, III and IV (grade I-mild injury; grade II-moderate injury; grade III and IV-severe liver injury). Laparotomy is mandatory if the patient's condition is unstable. By using the explorative laparotomy technique, the grade of liver injury is assessed, and accordingly the procedure is performed including suturing, ligation of the bleeding vessel, segmental resection, perihepatic packing, and so on. Morbidity and mortality of liver injury can be minimized with early diagnosis and appropriate management.
