Objective: we evaluated the indications and efficacy of non operative managementfor patients with blunt hepatic injury. Patients and methods: from 1/2006 to 12/2008, of the 287 blunt hepatic trauma patients underwent nonoperative management at Viet Duc hospital, 228 patients with haemodynamic stable or restabilised after resuscitation, without combination injuries required laparotomy. Result: the successful rate of the procedure is 93.9 percent, the good rate is 93 percent, the complication rate is 7 percent, the laparotomy conversion is 6.5 percent but there are only 3.5 percent related hepatic injury, one case missed bowel injury (0.4 percent), so the successful rate is 95.6 percent if including only blunt hepatic trauma. Conclusion: non operative management of blunt hepatic injury is safe and effective technique applicable to hemodynamically stable patients who lack other indications for laparotomy and who can be adequately monitored.
