Pyogenic liver abscesses: successful non-surgical therapy

Eleven consecutive patients with pyogenic liver abscesses were seen in a 20-month study period. Ten patients were treated with antibiotics alone. All ten had abscesses demonstrated by hepatic scintigraphy or sonography. In six patients purulent material was obtained by percutaneous aspiration of the liver. Blood-cultures were positive in each of the nine patients in whom they were obtained. Nine of the ten patients treated with antibiotics alone were cured; one died from complications of a liver biopsy. These results indicate that pyogenic liver abscesses can be effectively managed by medical therapy and that surgery is rarely required.
