Background
Hereditary spherocytosis (HS) is a common inherited disease affecting the erythrocyte membrane. Total splenectomy (TS) is effective in reducing hemolysis and decreasing the need of transfusions, but total removal of the spleen represents a potential risk factor for infectious and non-infectious complications. On the other hand, subtotal splenectomy (STS) could be an alternative therapy for HS. The aim of this study is to establish which surgical approach has the best outcome in HS.
Methods
All patients (n = 63) receiving splenectomy for HS between 2002 and 2016 from one institution were retrospectively reviewed. Hemoglobin and reticulocytes levels during preoperative and postoperative follow-up periods were compared. Additionally, a meta-analysis was performed analyzing data regarding hemoglobin and reticulocytes levels from several available studies.
Result
At 1-year follow-up, our clinical data showed that mean hemoglobin levels increased after TS from (mean ± SD) 9.77 ± 1.82 to 11.88 ± 2.08 g/dl, while after STS from 8.98 ± 1.66 to 11.87 ± 1.38 g/dl. At 3-year and 5-year follow-up after TS, we observed an increase from 9.77 ± 1.82 to 13.59 ± 2.03 and 13.46 ± 1.64 g/dl, respectively. At 3-year and 5-year follow-up after STS in our cohort, we observed an increase from 8.98 ± 1.66 to 13.21 ± 1.95 and 13.68 ± 1.65 g/dl, respectively. The meta-analysis (for a follow-up period of 1 year) showed that the hemoglobin levels increased with 2.61 g/dl (95% CI 2.15–3.08 g/dl; p < 0.001) after TS, and with 1.67 g/dl (95% CI 1.25–2.10 g/dl; p < 0.001) after STS.
Conclusion
We conclude that subtotal and minimally invasive splenectomy could be considered as the first line of treatment in severe HS cases, especially in children.
