[Contusion of the liver. Importance of associated lesions in polytraumatized patients].

Between January 1984 and June 1993, we treated 120 contusions of the liver in a situation of polytrauma. There were 24 patients in Stage I, 47 in Stage II, 22 in Stage III, 13 in Stage IV and 14 in Stage V according to the Organ Injury Scaling Committee of the American Association for the Surgery of Trauma. A total of 107 patients were operated. Polytrauma related mortality was high. Besides the gravity of the liver lesion, prognosis was a function of other associated intra or extra abdominal lesions. In our series, other associated lesions were the cause fo death in 26 patients (64%) and 15 deaths (36%) were directly related to the hepatic lesion. The gravity of the Stage V lesions was related both to the state of shock of operation and the difficulties in reestablishing haemostasis. Packing decreased the effect of hypovolaemia and coagulopathy. The prognosis of supra hepatic venous lesions and hepatic resections remain disastrous. Our surgical schema has changed towards more conservative surgery and, when haemodynamic stability has been achieved, to abstention and careful monitoring. Different extra-hepatic trauma causing damage to other organs directly compromises simple hepatic lesions. The result of our series confirms the correlation between mortality and the gravity of the polytrauma as evaluated according to the Injury Severity Score proposed by Baker.
