    Abstract:
    BACKGROUND: A current assessment of liver abscesses should allow for better understanding of the pathogenesis of the disease and improve the effectiveness of diagnosis and treatment. Amebic liver abscess occurs more commonly than pyogenic liver abscess on a worldwide basis. However, in the United States, pyogenic liver abscess predominates. The purpose of our study was to evaluate the etiology, management, morbidity, and mortality of all patients admitted to our medical center with diagnoses of pyogenic liver abscess between 1983 and 1996. METHODS: A retrospective chart review was performed on all patients admitted to our medical center, Louisiana State University Medical Center, Shreveport, with diagnoses of pyogenic liver abscess. RESULTS: Twenty patients were admitted with diagnoses of pyogenic liver abscess. The subjects were 65% (13/20) male and 65% (13/20) African-American and had an average age of 52 years. The most common presenting symptoms were fever and pain. The most common physical finding was right upper-quadrant tenderness. The most common etiologies of pyogenic liver abscesses were cryptogenic, trauma, and biliary, while portal vein was the source for only 10% of the cases. The right lobe of the liver was involved in 95% of the cases, and 70% of these liver abscesses were solitary. Computed tomography (CT)-and ultrasound-guided percutaneous drainage were performed in 85% (17/20) of patients with liver abscesses. One patient was treated by open drainage, three patients were treated with antibiotics alone, and three patients did not respond to aspiration and catheter placement, which subsequently required open drainage. The culture results were as follows: 50% were gram-negative organisms, 25% were gram-positive organisms, 10% were anaerobic organisms, and 15% of the abscess were sterile. Sixty percent of the positive abscess cultures were polymicrobial. CONCLUSIONS: CT scan- and ultrasound-guided percutaneous drainage of pyogenic liver abscesses were safe and effective methods of treatment. The right lobe of the liver was involved in 95% of cases. Although no one species predominated, gram-negative bacteria were the most common organism cultured, and 60% of the abscesses were polymicrobial. There was no in-house mortality in this review.
