Pyogenic liver abscess is an uncommon complication of intra-abdominal or biliary tract infection and is usually a polymicrobial infection associated with high mortality and high rates of relapse in western countries. However, over the past five and a half years, in the newly founded Taching Hospital, we have treated ninety-four patients (male-to-female ratio 1.4:1) with pyogenic liver abscesses. The abscesses were confirmed in all 94 patients by needle aspiration or operation. Eight patients (8.5%) died. Its clinical symptoms are, fever (90.4%), chills (84%), and right quadrant pain (54.2%). The majority of these abscesses are solitary (77.6%) and mostly found in the right lobe (82.9%).
