Abstract

The study aimed to investigate the long-term outcomes of laparoscopic splenectomy (LS) in Chinese patients with chronic idiopathic thrombocytopenic purpura (ITP). This was a retrospective analysis of 114 patients with ITP who underwent LS from 2001 to 2013. Patients were classified according to response at last contact: complete response (CR), partial response (PR), and no response (NR). Patients with CR had the highest platelet levels and patients with NR had the lowest. A correlation was observed between postoperative peak platelet count and platelet count on 2-month postoperative (r=0.829, P<0.01). In total, 27 patients showed NR to LS. Ten patients recurred within 3 years. The 140-month response rate to LS was 68%. Multivariate analysis showed that age and postoperative platelet count were independently associated with CR/PR. In conclusion, LS achieved good outcomes in Chinese patients with ITP. Age and postoperative peak platelet were independently associated with response.
