Background/Aims : The aim of this study was to evaluate the clinical features, radiologic findings, treatment modalities, and outcomes based on the origin of infection in patients with pyogenic liver abscesses. Methods : We retrospectively analysed the medical records of 118 patients who were treated for pyogenic liver abscesses between January 2004 and December 2006. Of the 118 patients, 56 patients had biliary risk factors. Results : The clinical characteristics were similar between the two groups, but the biliary risk group was characterized by an older age and the presence of jaundice. The size of the abscess was smaller in the group with biliary risk factors than in the cryptogenic group (p=0.02). Klebsiella pneumonia was the most common organism overall; however, Escherichia coli was more prevalent in the biliary risk group than in the cryptogenic group (p=0.03). Comparing the treatment modalities between the two groups, antibiotic therapy alone was more frequently used in the biliary group (p<0.01). The death rate was higher in the biliary group than in the non-biliary group (7.1 vs. 0.0%, p=0.04). The higher death rate in the biliary group was associated with multi-organ failure, absence of biliary drainage, and underlying diseases. Conclusions : There were differences between the two groups with respect to the size of the abscess, patient age, cultured organisms, and treatment modalities. The death rate was higher in the biliary group than the cryptogenic group. (Korean J Med 75:60-67, 2008)
