Abstract
BACKGROUND: Sclerotherapy has been described as a treatment option for nonparasitic pediatric splenic cysts; however, there are limited data on its long-term effectiveness. METHODS: We performed a retrospective review and prospective follow-up imaging study of children treated for nonparasitic splenic cysts at our institution during 2006-2015. Included patients had International Classification of Disease, Ninth Revision, Clinical Modification diagnosis code 289.59 or 759.0 and underwent either sclerotherapy or a partial splenic operation (partial splenectomy, cyst excision, or marsupialization). Charts were reviewed for demographics, imaging, treatments, and complications. Identified patients were contacted and asked to return for splenic ultrasonography. RESULTS: Six surgical patients and 19 sclerotherapy patients were identified. Sclerotherapy patients underwent a median of four treatments with a decrease in the size of the cyst or complete ablation in 89.5% (17/19). Of the two patients who underwent unsuccessful sclerotherapy, one patient had sclerotherapy with sotradecol and ethanol for eight treatments, developed infection, and underwent total splenectomy. The other patient did not improve with sclerotherapy and underwent partial splenectomy. Nine patients (eight patients treated with sclerotherapy and one patient treated with partial splenectomy) were successfully contacted and underwent follow-up imaging at a median follow-up of 2.4 y since last treatment. Of the eight patients treated with sclerotherapy, four patients remained cyst-free, three had small residual asymptomatic cysts stable in size, and one developed a recurrent small asymptomatic cyst; the patient treated with surgery had no recurrence. CONCLUSIONS: Sclerotherapy appears to be an effective and durable alternative treatment for children with splenic cysts.
