Nonoperative management of hepatic trauma.

In an attempt to determine whether selective, nonoperative management of hepatic trauma might be efficacious, a retrospective review of liver injuries was undertaken. Of the 48 patients with liver injuries identified, there were 34 men and 14 women with an average age of 28.5 years. Mechanism of injury consisted of blunt trauma in 23 patients, stab wounds in 14 patients, and 11 patients had gunshot wounds. There were 12 grade I injuries, 15 grade II injuries, 17 grade III injuries, 2 grade IV injuries, and 1 grade V injury. Diagnosis of liver trauma was made at the time of exploratory laparotomy in 15 patients and suggested by abdominal computed tomography (CT) scan in 18 patients; the remaining 15 patients had a positive peritoneal lavage which led to exploratory laparotomy. Following blunt trauma, 14 patients, all of whom underwent diagnostic abdominal CT scans which confirmed hepatic injury, had nonoperative treatment. All patients who received nonoperative management maintained stable vital signs and only five required transfusion. None of the patients who were treated nonoperatively developed complications or required delayed laparotomy. There were no deaths in this group. Of the 34 patients undergoing exploratory laparotomy, 19 required either no treatment or minor hepatorrhaphy. However, 17 of 25 patients with penetrating wounds had associated abdominal injuries which required operative treatment. Based on the information obtained in this review, it is recommended that stable patients with isolated hepatic injuries, secondary to blunt trauma confirmed by CT scan, may be managed nonoperatively. Due to the high frequency of associated injuries found in patients with penetrating trauma, nonoperative therapy is not advised.
