Liver abscess. Review of a 12-year experience.

Experience with liver abscess was reviewed to determine whether new trends in treatment have altered clinical outcome. Thirty-one cases of liver abscess were identified from 1973 to 1985. In this group there were ten deaths for a mortality rate of 32 per cent; the primary disease accounted for seven deaths. Significant predictors of liver abscess mortality were multiple abscesses, elevated bilirubin levels, and underlying disease. Percutaneous drainage was effective in three of four patients and should be attempted before operative intervention in selected patients.
