Splenic Abscess: A Single Institution Study and Review of the Literature

Purpose: The aim of this study was to review our experience with splenic abscesses, with respect to the relevant aspects of splenic abscesses and treatment outcomes. Materials and Methods: We reviewed the cases of 18 patients who had splenic abscesses and who were treated at our hospital from November 1993 to December 2008. Results: The most common symptom at presentation was abdominal pain in 12 patients (66.7%). The median duration from symptom onset until establishment of a diagnosis was 22 days. Streptococcus viridians was the most common pathogen (27.8%), follow by Klebsiella pneumoniae (22.2%). The mortality rate during the inpatient period and the previous 90 days was 16.6%. Three of four patients with Klebsiella pneumoniae showed a single abscess pocket. Four patients (22.2%) underwent percutaneous drainage, eight (44.5%) recieved antibiotic treatment only and six (33.3%) underwent splenectomy. Conclusion: There is no gold standard for treating splenic abscesses. Treatment should be customized for each patient.
