Abstract
This study represents a 6 year 4 month experience with blunt trauma to the liver of patients from the Maryland Institute for Emergency Medical Services Systems, a major regional trauma center. The significance of this study is that it describes a large, relatively homogeneous population and analyzes what the state of the art for liver trauma has been in a center dedicated solely to trauma that has a full-time staff of trained traumatologists. Three hundred twenty-three consecutive patients with blunt liver trauma are presented, representing 3.5% of 9271 patients admitted to the institute over the period of this study. Ninety per cent had associated traumatic injuries requiring operative intervention. A mortality rate of 31% (101 patients) was noted; 41.5% of the deaths, due primarily to liver injury, occurred intraoperatively during the initial operation following admission. The use of simple suture techniques and resectional debridement to control hemorrhage are advocated. Anatomic lobectomy, intracaval shunting, and hepatic artery ligation were uniformly unsuccessful. The use of drains was associated with a significantly increased incidence of infectious complications (p less than 0.00002).
