[Surgical-radiologic interventional treatment in liver abscess with Streptococcus anginosus Milleri].

Pyogenic liver abscess is a relatively rare disease, often concerning elderly patients in bad general condition and with underlying diseases. Out of a retrospective study (1984-1991) of 44 patients (f 43%, m 57%) with pyogenic liver abscesses and 12 patients (f 17%, m 83%) with amebic liver abscesses we present 5 patients with multifocal lesions due to Streptococcus anginosus Milleri--a special group concerning therapy and course of disease. The therapy was high-dose i.v. antibiotic therapy in all 5 cases and additional percutaneous drainage with pig-tail catheters--inserted under CT guidance--in 4 cases (1-5 catheters, time of drainage 6-63 days). The duration of hospitalisation was 15-73 days (median 45), intravenous antibiotic treatment lasted 4-40 days. After discharge oral antibiotics were continued for 14-42 days.
