To compare the clinical effectiveness of total splenectomy (TS) or partial splenectomy (PS) in pediatric hereditary spherocytosis, a systematic review and meta-analysis was performed (PROSPERO registration CRD42015030056). There were 14 observational studies comparing pre- and postoperative hematologic parameters. Secondary outcomes include in-hospital infections, surgical complications, symptomatic recurrence, and biliary disease. TS is more effective than PS to increase hemoglobin (3.6 g/dl vs. 2.2 g/dl) and reduce reticulocytes (12.5% vs. 6.5%) after 1 year; outcomes following PS are stable for at least 6 years. There were no cases of overwhelming postsplenectomy sepsis. A population-based patient registry is needed for long-term follow-up.
