心脏死亡供者供肝移植效果的荟萃分析

目的 评估心脏死亡器官捐献(DCD)供肝移植的效果.方法 检索美国国立医学图书馆国际性综合生物医学信息书目数据库(Pubmed/Medline数据库)、Embase数据库和Cochrane图书馆数据库中1950-2011年正式发表的英文文献,选取单中心研究.针对肝移植术后并发症的发生率,人、移植物存活率进行荟萃分析.结果 共纳入13篇单中心研究文献,包括5867例脑死亡器官捐献(DBD)肝移植和619例DCD肝移植.DCD肝移植术后发生胆道并发症的比值比(OR值)为2.5(95％可信区间为2.00～3.12),发生缺血性胆管炎的OR值为14.65(95％可信区间为6.51～32.99),发生原发性移植物无功能(PNF)的OR值为2.12(95％可信区间为1.33～3.36).DCD肝移植和DBD肝移植术后受者总体1年存活率分别为83.8％和87.2％,OR值为0.78(95％可信区间为0.59～1.02);移植物总体1年存活率分别为72.2％和82.4％,OR值为0.55(95％可信区间为0.45～0.68).DCD肝移植和DBD肝移植术后受者总体3年存活率分别为81.5％和78.9％,二者的差异无统计学意义(P＞0.05);移植物总体3年存活率分别为69.5％和73.6％,OR值为0.73(95％可信区间为0.56～0.94).结论 DCD肝移植术后胆道并发症发生率,尤其是缺血性胆管炎的发生率较高,但术后整体效果与DBD肝移植相当.

Mela-analysis of the outcomes of liver transplantation from donation after cardiac death donors

Objective To conduct a meta-analysis to evaluate the outcomes of donation after cardiac death (DCD) compared with donation after brain death (DBD) liver transplantatior.Methods The MELDINE (1950-2011),EMBASE,and Cochrane Library databases were searched.All original single institution studies reporting outcomes of comparing donation after DCD and DBD liver transplantation were considered.A meta-analysis of complication incidence and patients/grafts survival after liver transplantation was conducted.Odds ratios (OR) and 95 ％ confidence intervals (CI) based on random effects models were calculated.Results Thirteen studies,all retrospective cohort studies,involving 5867 DCD and 619 DBD recipients,were included.DCD recipients had a 2.5 times increased odds of biliary complications (95 ％ CI =2.0～3.12),an 11.24 times increased odds of ischemic cholangiopathy (IC) (95 ％ CI =5.58 ～ 22.64 ),and a 2.12 times increased odds of primary nonfunction (PNF).DCD recipients also experienced lower odds of 1-year patient survival (OR =0.78,95 ％ CI=0.59～1.02),83.8 ％,87.2 ％,separately,and 1-year graft survival (OR=0.55,95％ CI=0.45～0.68),72.2 ％ and 82.4 ％,separately.Three-year patient survival was present in 81.5 ％ of DCD vs 78.9 ％ of DBD,which has no significant difference.The 3-year graft survival was lower inDCD than that in DBD (OR =0.73,95 ％ CI =0.56～0.94),69.5 ％ and 73.6％,separately.Conclusion DCD liver transplantation is associated with higher risks of biliary complications.But regarding the comparable general outcomes with DBD transplantation,DCD could be a source of liver.
