Factors determining the mortality and morbidity in hepatic injuries. Analysis of 108 cases.

The experience with 108 cases of hepatic injuries was reviewed retrospectively and a classification based on the severity of the hepatic injury was used to group these patients accordingly. Using this criteria, the factors determining the observed morbidity and mortality were analyzed. Hepatic injuries amenable to relatively simple surgical treatment were found in 72 patients (67%). Nine deaths occurring in this group were attributed to the commonly encountered associated injuries inside and outside the abdomen. Moderately severe imjuries requiring suturing of the hepatic parenchyma and ligation of injured vessels and bile ducts were seen in 15 patients (14%). Two of these patients died. Severe hepatic injuries resulting in major blood loss requiring partial hepatectomy were seen in 21 patients (19%). Seven of the eight deaths (7.4%) attributable to the hepatic injury occurred in this group. As noted, ten other patients died from causes other than the hepatic injury for an overall mortality of 16.7%. A pre-established patient management program based on the classification of hepatic injuries is proposed as a method for improving the management of patients with hepatic injuries.
