Most hepatic traumas are easily cured, but the series of 135 consecutive hepatic wounds reported in the present paper is unusual in that the patients were specifically recruited from among patients subjected to neurosurgical or spinal operations, 25% of whom sustained severe hepatic injuries (classes IV and V) as a result of the surgery. The postoperative mortality was analyzed according to such potentially predictive factors as severity of the hepatic wound, the concomitant extraabdominal lesions, the initial shock, and the kind of surgical treatment. The statistical comparison of the factors affecting the results was analyzed by the Chi-square test. The postoperative mortality rate was 24.4% (33 deaths). This mortality rate is evidently related to the severity of the hepatic lesions and to the frequent associated lesions. The 14 deaths from benign and moderate hepatic injuries were due to concomitant lesions. Among the 19 deaths from severe lesions, 12 were directly related to the severity of the hepatic injury and 7 to associated wounds. Complications directly related to the hepatic trauma occurred in 39 cases with 16 deaths. In general, conservative surgical treatment can be performed with quite low mortality. Among the patients who require hepatic resection one of two dies of hemorrhage or coagulopathy. Among conservative procedures, perihepatic packing has proved to be efficient and safe. If perioperative cholangiography has excluded any leak from a major bilde duct, septic complications are rare. Therefore, the surgical treatment of hepatic trauma should be as conservative as possible, because this can stop hemorrhage and decrease the risk of coagulopathy.(ABSTRACT TRUNCATED AT 250 WORDS)
