    Author: Rismiller K, Haaga J, Siegel C, Ammori JB.
    Journal: HPB (Oxford); 2017 Oct; 19(10):889-893. PubMed ID: 28693978.
    Abstract:
    BACKGROUND: Despite equivocal evidence, non-surgical management for pyogenic liver abscess (PLA) has become the standard of care at most institutions with surgery relegated to salvage therapy for those who fail less invasive means. The aim of this study was to describe the outcomes of a step-up approach to PLA management. METHODS: A retrospective chart review was conducted at a single institution for patients diagnosed with PLA over a 10-year period. Demographic, radiologic, microbiological, treatment, and outcomes data were collected and analyzed. RESULTS: 64 patients with PLA were identified. Initial treatment included antibiotics alone (n = 9), percutaneous drainage (PD) (n = 54), and surgery (n = 1). Surgery was ultimately required in 8 patients while 50 were cured with PD and 4 with antibiotics alone. Two (3%) patients died. Overall, PD carried an 85% success rate. CONCLUSION: PLA patients should be initially treated non-operatively, barring indications for emergent surgery or inaccessibility for PD. Surgery can be reserved for failure of PD.
