Treatment Strategy for Blunt Hepatic Trauma: Analysis of 183 Consecutive Cases

Abstract

Non-operative management of hemodynamically stable trauma has proven successful; however laparotomy for hemodynamically unstable patients is still insufficient. We evaluated the results of treating blunt hepatic injury and appraised the appropriate surgical procedures. We analyzed the demographics, vital status, and severity of hepatic and concomitant organ injuries of 183 consecutive patients with blunt hepatic injuries between January 2001 and December 2008, retrospectively. Twenty five of 183 patients died before the treatment was selected. The initial management was operative for 24 and non-operative for 134, 15 of whom later required laparotomy. Of the 134 treated non-operatively, 2 died after arterial embolization for pelvic fractures. Twelve patients died postoperatively: 6 of the hepatic injury and 6 of concomitant organ injuries. Considering Liver Injury Scale of operated patients, there was no liver-related death with grades I-III; however, liver-related mortality of grades IV and V was 37.5%. The incidence of liver-related deaths after anatomical resection was 0% of patients with grade IV, but 50% of patients with grade V, despite anatomical resection being the only effective procedure for grade V. The results of anatomical resection for grade IV is satisfactory, but additional strategies are still required for grade V.
