摘要
目的比较超声内镜引导下的胆道引流(EUS-BD)与经皮经肝穿刺胆道引流(PTBD)治疗恶性梗阻性黄疸的疗效。方法计算机检索PubMed、EMbase、The Cochrane Library、CBM、WanFang Data和CNKI数据库,搜集EUS-BD与PTBD治疗恶性梗阻性黄疸患者疗效比较的随机对照试验(RCT)和队列研究,检索时限均从建库至2018年11月30日。由2名研究者独立筛选文献、提取资料并评价纳入研究的偏倚风险后采用RevMan5.3软件进行meta分析。结果本研究共纳入3个RCT和6个队列研究,共496例患者。meta分析结果显示,EUS-BD组的术后并发症发生率[OR=0.30,95%CI(0.20,0.47),P<0.000 01]、术后再手术干预率[OR=0.11, 95%CI(0.06,0.22),P<0.000 01]、住院时间[MD=–3.42,95%CI(–6.72,–0.13),P=0.04]、住院费用[SMD=–0.83,95%CI(–1.16,–0.49),P<0.000 01]明显低(或少)于PTBD组。在技术成功率[OR=0.88,95%CI(0.20,3.85),P=0.86]和临床有效率[OR=1.73,95%CI(0.97,3.11),P=0.06]方面2组间比较差异均无统计学意义。结论现有证据表明,与PTBD相比,EUS-BD在治疗恶性梗阻性黄疸患者方面具有术后并发症发生率低、术后再手术干预率低、住院时间短、费用低等优点,而在技术成功率和临床有效率方面两者无明显差异,但由于受纳入文献数量和质量限制,上述结论尚需开展更多高质量研究予以验证。
Objective To systematically review efficacy of endoscopic ultrasonography guided biliary drainage(EUS-BD)and percutaneous transhepatic biliary drainage(PTBD)on patients with malignant obstructive jaundice.Methods The PubMed,EMbase,The Cochrane Library,CBM,WanFang Data,and CNKI were searched online to collect the randomized controlled trials or cohort studies of EUS-BD versus PTBD on the patients with malignant obstructive jaundice from inception to November 30,2018.Two reviewers independently screened the literatures,extracted the data and assessed the risk of bias of included the studies,then the meta-analysis was performed by using the RevMan 5.3software.Results Three randomized controlled trials and 6 cohort studies involving 496 patients were included.The results of meta-analysis showed that:compared with the PTBD,the EUS-BD had the lower occurrence of complications[OR=0.30,95%CI(0.20,0.47),P<0.000 01],lower rate of reintervention[OR=0.11,95%CI(0.06,0.22),P<0.000 01],shorter hospital stay[MD=–3.42,95%CI(–6.72,–0.13),P=0.04],and less hospital costs[SMD=–0.83,95%CI(–1.16,–0.49),P<0.000 01].There were no significant differences in the technical success rate[OR=0.88,95%CI(0.20,3.85),P=0.86]and clinical effective rate[OR=1.73,95%CI(0.97,3.11),P=0.06]between the two groups.Conclusions Current evidence shows that EUS-BD has some advantages of lower occurrence of complications,lower rate of reintervention,shorter hospital stay,and less hospital costs in treatment of patients with malignant obstructive jaundice as compared with PTBD.There are no significant differences between two groups in technical success rate and clinical effective rate.Due to limited quality and quantity of included studies,more high quality studies required to be verified above conclusions.
