One hundred and sixty-two patients with solitary or multiple pyogenic liver abscesses received surgical or medical treatment in the past 8 years. Fifty-seven patients were treated medically (medical group), 62 patients received medical treatment plus sonogram-guided percutaneous drainage (PCD group), and 43 patients received surgical drainage (surgical group). Aerobic gram-negative rods were the predominant causative microorganisms. Klebsiella pneumoniae was the most common microorganism, occurring in 46.9% (76/162) of the cases. Anaerobes occurred in 16.7% (27/162) of the cases. In the evaluation of treatment, the success rates for these three groups were: medical group, 59.6% (34/57); PCD group, 90.3% (56/62); and surgical group, 83.7% (36/43). This retrospective study confirms evidence from a small series that medical treatment plus percutaneous catheter drainage is efficient and more convenient than conventional surgical drainage for pyogenic liver abscesses. The frequent severe septic emboli to distant organs noted in this series (11.1%; 18/162) are quite unusual and should be anticipated in the future.
