The role of percutaneous US-guided drainage in the treatment of splenic abscess. Case report and review of the literature

Abstract

Splenic abscess is an uncommon but potentially life-threatening disease that generally occurs in patients with neoplasia, immunodeficiency, hemoglobinopathies, trauma, metastatic infection, splenic infarction and diabetes. Splenic abscess should be considered in a patient with fever, left upper abdominal pain, and leukocytosis. Splenectomy has been the gold standard treatment for splenic abscess, however, burdened by high morbidity rate related clinical conditions of the patient. With the recent development of minimally invasive techniques and percutaneous US- or CT-guided procedures, the placement of a drainage has achieved excellent results with resolution of the disease in a high percentage of cases with low morbidity and negligible mortality. Percutaneous drainage is indicated for uniloculated or biloculated abscesses and for high risk surgical patients. It is a reliable technique with a high rate of therapeutical success and low costs compared to surgery. Other advantages include avoiding risks of intra-abdominal spillage and perioperative complications and saving time, along with a better patient compliance and an easier nursing care. The authors describe a case of splenic abscess treated by percutaneous US-guided drainage. Our results suggest that ultrasound-guided percutaneous drainage is a safe and feasible alternative to surgery in the treatment of splenic abscesses. In addition, it allows spleen preservation.
