[Sonographic percutaneous drainage of liver abscesses]

13 patients with pyogenic liver abscess and five patients with amoebic abscess underwent percutaneous drainage of the abscesses using the Seldinger (n = 8) or trocar technique (n = 11). The results showed that the trocar method was easier and faster to perform and well tolerated by the patients. No complications were observed despite of one case of transient peritonitis caused by a dislocated catheter. One patient with pyogenic liver abscess died of septic shock. All other patients were successfully treated, using local drainage and systemic antibiotic therapy.
