title: Hepatic trauma: risk factors influencing outcome.
abstract: This retrospective study analyses the fate and associated risk factors of 99 patients who underwent laparotomy for hepatic trauma from 1977 to 1986. Blunt trauma (88 patients) and stab wounds (7 patients) had mortality rates of 36 and 14 per cent respectively. The overall death rate was 35 per cent. Multiple trauma patients had a significantly higher mortality for each additional system that was seriously injured. Pre-operative shock raised the mortality from 20 to 58 per cent (P less than 0.001). For patients over 50 years of age, the mortality rate increased from 30 (younger patients) to 63 per cent (P = 0.028). Minor hepatic wounds required relatively simple surgical measures in 60 patients, yet 13 died (22 per cent) of other causes. More sophisticated surgical management was applied to 27 major hepatic lesions, with 10 deaths (37 per cent). Twelve patients (seven with minor and five with major hepatic wounds) died before surgical treatment of the liver injury could be undertaken. The overall mortality rate of major hepatic wounds was 47 per cent and for minor wounds 30 per cent. However, the difference was not significant (P = 0.152). Resection was resorted to in 15 patients, 5 of whom subsequently died (33 per cent). Classical hepatic lobectomy led to 4 deaths (50 per cent). Among the 35 deaths, 6 were due to the hepatic trauma itself (5 exsanguinations and 1 intra-abdominal sepsis). Isolated hepatic injury was fatal in three patients. We believe that conservative surgical measures should be used whenever possible in patients with hepatic trauma, especially when risk factors are encountered.
