Background: Pyogenic liver abscesses (PLA) are frequent in immunosuppressed patients. We review the characteristics of patients with PLA at a tertiary academic Spanish hospital in Asturias.

Methods: A retrospective observational study for 10 years, between 2006-2015. Epidemiological, clinical, analytical characteristics, treatment and hospital stay of the patients with PLA were analyzed.

Results: 99 patients, 62 (62.6%) men, with age ≥65 years (72.7%). The most frequent etiology was: Biliary (40%), postsurgical (15%) and intestinal origin (11%). The most frequent clinical signs were fever, showing significant differences, abdominal pain (p=0.001) and nausea (p=0.02) between biliary PLA and the rest of the PLA. Microbiological results were confirmed in 63% (62 cases). All were treated with antibiotic therapy, along with percutaneous drainage (44.4% (44 cases)); and surgical drainage (12.1% (12 cases)). The overall mean stay was 23.1 days without significant differences between those treated with percutaneous drainage or surgical drainage.

Conclusion: PLA predominate in patients ≥65 years. Biliary PLA are the most frequent, diagnosed at an older age than the intestinal PLA (p=0.005).

- The treatment is based on systemic antibiotherapy and percutaneous drainage, especially in PLA only >5cm (p=0.019).

- There are no significant differences in average stay of patients treated with percutaneous drainage or surgical drainage.
