Splenic Abscess in Qatar: A Single-Center Experience

Background & Objectives: Splenic abscess (SA) is a rare clinical entity. There is a lack of information on SA in most Arab and Gulf countries, including Qatar. This study describes the demographics, clinical features, microbiologic etiologies, treatments, and outcomes of patients with SA at the largest tertiary medical center in Qatar over the previous six years. Methods: This retrospective observational study was conducted at Hamad general hospital. It involved all patients of 18 years old or above who were admitted with the diagnosis of SA for the period between January 1, 2015, and December 31, 2020. Results: We recruited 25 patients, of which 14 (56%) were males, and 11 (44%) were females. The mean age ( ± SD) of them was 48.64 ± 19.08 years. The mean illness duration was 22.88 ± 11.88 days. Fever was the most common presenting symptom and was found in 21 (84%) cases, whereas bacteremia was the most predisposing factor found in 15 (60%) patients. The etiology of SA was bacterial in 16 cases (64%), mixed (fungal and bacterial) in one (4%), and tuberculous in one (4%), whereas the etiological agent was unidentified in seven (28%) cases. Intravenous antimicrobial therapy was administered empirically in all patients. However, seven patients (28%) received intravenous antibiotics as the only treatment modality for SA, 15 patients (60%) underwent percutaneous drainage with a pigtail catheter, and two patients underwent splenectomy. The inhospital mortality was three (12%). Conclusions: This study showed that SA could be caused by various organisms that should be isolated to guide the choice of antimicrobial agents. An abdominal computed tomography is a good diagnostic modality, whereas computed tomography- and ultrasonography-guided percutaneous drainage were efficient therapeutic options that reduce the need for surgery.
