title: [Pyogenic liver abscess. Review of 33 cases].
abstract: Thirty three cases of pyogenic liver abscess, (24 single and 9 multiple), diagnosed in our department during the past 6 years, were reviewed. Mean patient age was 54 years with a male predominance over females (1.5:1). The most frequently encountered underlying pathology was bile duct disease (33%), followed by previous liver disease (21%). Causal pathology could not be found in 4 cases (12%). The most frequent sign was fever (76%). Diagnosis was made by clinical picture and complementary exam (echography, CT scan and hepatic gammagraphy) in 29 cases (88%). Blood and pus cultures were positive in 47 and 67% of cases respectively. Thirty nine per cent of microbial abscesses were polymicrobial. E. coli and S. milleri were the most frequently isolated. No micro-organism were identified in 5 cases (15%). Antibiotic treatment was given to 33 patients. Surgical drainage was performed in 24 cases and percutaneous drainage in 7 patients. Two patients received antibiotics exclusively. Five patients died (15%), three of whom had a multiple abscess (33%) and the other two had a single abscess (8%). The efficacy of percutaneous drainage for diagnosis and treatment is analyzed reviewing recent literature.
