PURPOSE:

We studied to compare computed tomographic(CT) findings of liver injury with management methods in adults and, moreover, to present the CT basis for the management. MATERIALS AND

METHODS:

We retrospectively reviewed CT scans of 43 adults diagnosed as liver injury during a 66-month period. Thirty-eight patients were hemodynamically stable. Thirty-two of them were managed conservatively, whereas six managed operatively. Five unstable patients underwent emergency operation. We classified CT findings according to the severity of liver injuries(ie, hematoma, laceration, and periportal tracking) and hemperitoneum, ranging from grade 1 to 5 and from 0 to 3+, respectively. Thus, we compared the CT classificafions with their management(ie, operation rate), especially hemodynamically stable patients.

RESULTS:

Operation rates of all patients and hemodynamically stable patients were 26% and 16%, respectively. Operation rate at each grade of liver injury was low, especially in hemodynamically stable, despite relatively high operation rate in grade 4. Operation rate of 3+ hemoperitoneum was 100%, including hemodynamically stable patients, in contrast to otherwise low operation rate of others.

CONCLUSION:

Most liver injury in adults, including grade 4, were managed conservatively, especially hemodynamically stable. Though large amount of hemoperitoneum(ie, 3+) required operation, most hemoperitoeum were managed conservatively. Thus, CT findings of liver injury is helpful in the decision for the management method.
