Platelet safety range before splenectomy for hypersplenism : based on 244 cases of splenectomy in hepatolenticular degeneration patients

Background and study aims : To investigate the safety and efficacy of splenectomy for hepatolenticular degeneration (HLD) patients with PLT less than 20 × 109/L. Patients and methods : A total of 244 HLD patients with hyper-splenism underwent splenectomy. According to the preopera-tive PLT values, the patients were divided into three groups : group A of 53 patients with PLT < 20 × 109/L ; group B of 92 patients with 20 × 109/L ≤ PLT ≤ 30 × 109/L ; group C of 99 patients with PLT > 30 × 109/L. General information including : blood cell counts, liver function , coagulation function 1 day before sugery and 1, 7, 14 days after surgery ; intraoperative blood loss ; operation time ; vital signs at the beginning, at 60 minutes and the end of the operation. Pressure and blood oxygen ; postoperative drainage ; postoperative complications and mortality. Results : Blood cell counts, liver function, and coagulation func-tion were improved after splenectomy in three groups (P0.05). Conclusion : For HLD patients with hypersplenism, it is safe and effective to conduct splenectomy under PLT < 20 × 109/L.
