As evidence-based strategies to the clinical management of Barrett's esophagus (BE) are lacking, we have carried out a systematic review and meta-analysis of all published randomized controlled trials with the aim of evaluating the value of different approaches in the treatment of BE. Searches were conducted in the databases PUBMED, EMBASE, and Cochrane Library. Thirteen randomized clinical trials that fulfilled the inclusion criteria and addressed the clinical questions of this analysis were assessed in more detail. Based on our search, neither the pharmacological nor surgical therapies currently available for reflux appear to achieve complete regression of BE and the elimination of the cancer risk associated with it. In contrast, endoscopic ablative techniques are capable of achieving endoscopic and histological reversal of BE, with ablation by argon plasma coagulation (APC) appearing to be more effective than treatment with photodynamic therapy (PDT) [odds ratio (OR) 3.46, 95% confidence interval (CI) 1.67-7.81, P = 0.0008]. There was no statistically significant difference between APC and multipolar electrocoagulation (MPEC) in terms of the efficacy to achieve regression of BE (OR 2.01, 95% CI 0.77-5.23, P = 0.15). In conclusion, there have been only a limited number of randomized controlled trials that compare treatments for BE. The pharmacological therapy, antireflux surgery, and endoscopic ablative techniques are promising in terms of treating BE, but the studies carried out to date have had no adequate power to assess the effect of treatment on reducing and preventing progression to adenocarcinoma.
由于缺乏针对巴雷特食管(BE)临床管理的循证策略,我们对所有已发表的随机对照试验进行了系统评价和荟萃分析,旨在评估不同方法在治疗BE中的价值。在PUBMED、EMBASE和Cochrane图书馆数据库中进行了检索。对13项符合纳入标准并涉及本分析临床问题的随机临床试验进行了更详细的评估。基于我们的检索,目前可用于反流的药物治疗和手术治疗似乎都无法使BE完全消退并消除与之相关的癌症风险。相比之下,内镜消融技术能够实现BE的内镜和组织学逆转,氩等离子体凝固(APC)消融似乎比光动力疗法(PDT)治疗更有效[比值比(OR)3.46,95%置信区间(CI)1.67 - 7.81,P = 0.0008]。在实现BE消退的疗效方面,APC和多极电凝(MPEC)之间没有统计学显著差异(OR 2.01,95% CI 0.77 - 5.23,P = 0.15)。总之,比较BE治疗方法的随机对照试验数量有限。药物治疗、抗反流手术和内镜消融技术在治疗BE方面很有前景,但迄今为止开展的研究尚无足够的效力来评估治疗对减少和预防进展为腺癌的效果。
