title: Pyogenic Liver Abscess.
abstract: The percutaneous approach-specifically, ultrasound-guided percutaneous catheter drainage-associated with intravenous administration of antibiotics is the therapy of choice in patients with single or multiple pyogenic liver abscesses. The initial empiric antibiotic therapy should be modified based on results of blood and pus cultures. Surgery should be reserved for patients in whom antibiotic therapy and percutaneous drainage is unsuccessful.
