Aim: Children with juvenile myelomonocytic leukemia (JMML) and myelodysplastic syndrome (MDS) may require splenectomy before blood marrow transplantation (BMT) or in cases that had persistent thrombocytopenia, increased transfusion requirement, massive splenomegaly but not had suitable donor for BMT. Children who underwent splenectomy because of JMML and MDS were evaluated for results of surgical treatment. Methods: Children who required splenectomy with a diagnosis of JMML and MDS between 2000 - 2015 were evaluated for age, sex, preoperative and postoperative blood counts, transfusion requirements, size of spleen, time between diagnosis and splenectomy and complication of surgery retrospectively. Results: Since 2000, ten patients who underwent splenectomy because of JMML (n=9) and MDS (n=1) were included. This indication accounts 5.4% of all splenectomies in the same period. In 60% of cases, splenectomy was performed in patients who had no suitable donor for BMT, whereas 40% performed before BMT. The mean age of the patients was 43.2 months (21-91 months) and male female ratio was 7:3. Mean size of spleen was 14.8 cm (10-20 cm). The mean time interval between diagnosis and splenectomy was 21 months (2-80 months). All patients had increased levels of hemoglobin and thrombocyte after splenectomy. Transfusion requirement before splenectomy was 2.2/month (1-3) and after splenectomy was 1.9/month (0-4). None of the patients had early complication, whereas one patient with BMT had posttransplant sepsis. Conclusion: Patients with JMML and MDS may require splenectomy before BMT or because of persistent thrombocytopenia, increased transfusion requirement, massive splenomegaly. Although, increased complication rate was suggested in these cases, results of surgical treatment did not differ from splenectomies with other indications.
