摘  要:目的评价食管静脉曲张套扎术(EVL)和β-受体阻滞剂(BB)预防肝硬化初次静脉破裂出血的有效性和安全性。方法计算机检索Cochrane临床对照试验资料库(2006年第4期)、MEDLINE(1966年至2006年11月)、EMBASE(1985年至2006年11月)和中国期刊全文数据库(1994-2006年),并辅以手工检索有关EVL和BB预防食管静脉曲张初次破裂出血的随机对照临床试验,按Cochrane协作网推荐的方法进行Meta分析。结果共纳入8个随机对照试验(RCT)。Meta分析结果显示,EVL和BB比较,EVL可降低肝硬化初次静脉破裂出血的发生率[相对危险度(RR)=0.63,95%可信区间(CI):0.46—0.85;P=0,003;相对危险度减少(RRR)=0.37,需要治疗的患者数(NNT)为12例『和严重副反应发生率(RR=0.23,95%CI:0,12~0.43;P〈0.01;RRR=0.77,NNT为8例);但二者对总病死率的影响差异无显著性意义(RR=1.03,95%CI:0.81~1.31;P=0.82)。结论预防肝硬化初次静脉破裂出血EVL比BB更有效和安全。Objective To evaluate the efficacy and safety of endoscopic variceal ligation(EVL) with β-blockers (BB)in prophylaxis on the rate of first esophageal variceal bleeding in patients with cirrhosis. Methods We searched Cochrane Central Register of Controlled Trials (4th Quarter 2006 ), M EDLIN E ( 1966-2006 - 10 ), EMBASE ( 1985-2006 - 10 ), CJFD (1994-2006) and handsearched the related journals to identify Randomized Controlled Trials (RCT) of endoscopic variceal ligation(EVL) and β-blockers for prevention of first variceal bleeding in cirrhosis. Meta-analysis was conducted using the method recommended by The Cochrane Collaboration. Results Eight trials were included. Summary RR of metaanalysis showed a significant reduction in EVL group in rate of first variceal hemorrhage( RR = 0. 63,95% C1:0. 46,0. 85 ; P = 0. 0003 ; RRR = 0. 37, N NT = 12) and severe adverse events ( RR = 0. 23,95 % C1:0. 12,0. 43 ;P 〈 0. 01 ; RRR = 0. 77, NNT = 8). But there were no statistically significant difference in total mortality between EVL and BB( RR = 1.03,95% C1:0. 81,1.31 ;P = 0. 82). Conclusion Variceal ligation is safe and more effective than β-blockers for the prevention of first variceal bleeding in cirrhotic patients.
