Successful medical treatment of pyogenic liver abscess.

Between 1976 and 1978, 6 patients with proven or probable pyogenic liver abscess were successfully treated at Los Angeles County-University of Southern California Medical Center without surgical drainage. Although surgical therapy is necessary in patients with coexisting intraabdominal pathology, antibiotic therapy without surgical intervention is an option to be considered in patients with pyogenic liver abscess and no evidence of other intraabdominal disease.
