全胃切除后间置空肠代胃与Roux-en-Y吻合两种消化道重建方式远期并发症及生活质量比较的Meta分析

目的 比较胃癌全胃切除后间置空肠代胃术与Roux-en-Y吻合两种消化道重建方式术后远期并发症及患者的生活质量,为全胃切除后消化道重建方式的选择提供循证医学依据.方法 由两名研究者以“Gastrectomy”、“Roux-en-Y”和“Interposition”以及“全胃切除”、“间置空肠”为主题词和关键词检索PubMed、EMBASE、Cochrane、Library和Google Scholer等英文数据库和中文期刊全文数据库、中国生物医学文献数据库等,对纳入的研究文献进行数据提取并核对,采用RevMan5.0软件进行数据处理.结果 共纳入10篇文献计1628例胃癌全胃切除病例,其中消化道重建采用间置空肠代胃术728例,采用Roux-en-Y吻合术954例.与Roux-en-Y吻合术相比,间置空肠代胃术有助于降低患者的倾倒综合征发生率(OR=0.19,95％CI:0.11～0.34,P＜0.01)、提高预后营养指数(WMD=6.02,95％CI:1.82～10.22,P＜0.01)并改善术后体质量减轻程度(WMD=-2.45,95％CI:-3.81～-1.71,P＜0.01),而两者在手术时间、住院时间及反流性食管炎发生率方面的差异则无统计学意义(均P＞0.05).结论 与Roux-en-Y吻合术相比,全胃切除后采用间置空肠代胃术进行消化道重建的胃癌患者,术后远期并发症发生率低,生活质量改善明显.

Meta-analysis on comparison of long-term complications and quality of life between two digestive tract reconstruction techniques following total gastrectomy

Objective To compare the incidence of postoperative long-term complications and quality of life between two digestive tract reconstruction techniques after total gastrectomy in order to provide evidence for clinical practice. Methods A systematic literature search was carried out to obtain studies of randomized controlled trials （RCTs） of reconstruction techniques including jejunal interposition and Roux-en-Y. Data extracted from RCTs for meta-analysis were independently assessed by two reviewers. A meta-analysis was performed by RevMan5.0 software. Results A total of 1628 gastric cancer cases undergoing total gastrectomy from 10 RCTs were eligible for inclusion, among whom 728 received jejunal interposition reconstruction and 954 Roux-en-Y anastomosis. As compared with Roux-en-Y anastomosis, jejunal interposition reconstruction significantly decreased the incidence of dumping syndrome （OR =0.19, 95% CI：0.11-0.34, P〈0.01 ）, increased the prognostic nutritional index （WMD=6.02, 95%C1：1.82-10.22, P〈0.01）, and improved the body weight postoperatively （WMD=-2.45, 95%CI： -3.81--1.71 ,P〈0.01）. Meanwhile, jejurial interposition reconstruction did not prolong operative time and hospital stay （both P〉0.05）. Conclusion Jejunal interposition has better efficacy t7han Roux-en-Y in dumping syndrome and quality of life, and is a reasonable and effective digestive tract reconstruction for long-term survival of gastric cancer patients.
