The aim of this research was to assess operative outcomes and hematological results of a large series of patients treated with LS for chronic immune thrombocytopenic purpura （ITP） and to determine which clinical variables predict favorable hematological outcome.Methods LS was successfully performed for 154 patients with chronic ITP from September 1999 to April 2009 at the First Affiliated Hospital of Sun Yat-sen University. Operative outcomes were assessed retrospectively. Long-term follow-up data were obtained from outpatient medical records and phone interviews. Clinical and laboratory variables （including gender, age, disease duration before surgery, previous response to steroids, preoperative platelet count, and postoperative peak platelet count） were evaluated by univariate analysis to identify potential predictors of hematological outcome. Multivariate Logistic regression model was used to determine independent predictors of hematological outcome.Results One patient died from subphrenic abscess and postoperative sepsis. The overall major morbidity rate was 8.4%. None of the patients required a second surgery for complications. Of the 127 patients available for a mean follow-up of 43.6 months （range 9-114 months）, the overall initial response （i.e., at two months after LS） and long-term response to LS were achieved in 89.0% and 80.3%, respectively. Five patients （3.9%） developed pneumonia 3-35 months after LS. Univariate analysis showed a significant difference in mean age between responders （29.1 years） and nonresponders （38.8 years; P ＜0.05）. Patients who responded to steroid therapy had better hematological outcome than those who did not respond （P ＜0.05）. Compared to nonresponders, responders to LS had a significantly higher postoperative peak platelet count （404x109/展开更多
