Résumé
Objective To study the results of splenectomy for patients with idiopathic thrombocytopenic purpura(ITP), which refractory to medical therapy or with repeat recurrence of symptoms. Methods 58 ITP (patients) who failed to respond to conservative management were treated with splenectomy and the clinical (outcome) was observed. Postoperatively, 52 cases were followed up for 6 months to 12 years, and in 48 of these cases the followup was more than 1 year. Results Platelet count recovered to normal(≥100?10~9/L ) two weeks after operation in 47 cases(81.03%). The total effective rate was 79.31% when (followed-up) for 2 months, 78.85% when followed-up for 6 months and 11 cases had recurrence. (Conclusions) Splenectomy is a safe and effective therapy for patients with ITP who failed to respond to (conservative) management or have relapse of ITP. Patients who showed temporary response to preoperative (steroid) therapy and those who had an early or a high amplitude of increase of platelet count after operation have better prognosis.
