Patient: I hope you can talk about the treatment of childhood idiopathic thrombocytopenic purpura (ITP). The first thing is to try not to cut the spleen of this patient, because if the adrenal corticosteroid treatment is not good, after cutting the spleen is often not very satisfactory, if you want to cut the spleen we are in principle not suitable for childhood, because after cutting the spleen of the patient easily combined with various coccus infection, affecting the quality of life, and also the risk of infection. Therefore, we advocate that spleen excision should be done in adulthood as much as possible.
