梗阻性黄疸术前胆道引流疗效分析

目的 系统评价梗阻性黄疸术前胆道引流 （preoperative biliary drainage，PBD）的临床效益。 方法 采用Cochrane系统评价方法, 检索1966-2010年Cochrane图书馆临床对照试验数据库、PubMed、Embase、Cancer lit等数据库，2名评价员独立提取信息并评价文献质量后交叉比对，评价指标包括总体病死率、总体并发症发生率及术后并发症发生率，采用RevMan 4.2软件进行Meta分析。 结果 共有8篇文献进入Meta分析，累积样本含量728例。与直接手术组相比，PBD总体病死率（OR 1.08，95%CI 0.68～1.73，P=0.74）、总体并发症发生率（OR 1.72，95%CI 0.86～3.45，P=0.13）及术后并发症发生率（OR 0.6，95%CI 0.35～1.03，P=0.06）差异无统计学意义。 结论 PBD操作本身的并发症抵消了其可能的临床益处，目前临床需慎重开展。
