全腹腔镜全胃切除术中食管空肠overlap吻合术安全性和有效性的Meta分析

Meta analysis of safety and effectiveness of anastomosis of esophagus and jejunum overlap in total laparoscopic total gastrectomy

目的:系统评价和比较全腹腔镜全胃切除术中overlap食管空肠吻合术和传统食管空肠吻合术治疗胃癌的安全性和有效性,为临床实践提供循证医学证据。方法:通过计算机检索国内外数据库PubMed、Embase、Cochrane Library、Web of Science、知网、万方、维普,检索时限为各大数据库建库至2022年1月。获得相关文献,逐步筛选,纳入符合条件的研究,采用Cochrane ROB偏倚风险评估工具和NOS量表对文章进行质量评价,提取高质量文献中所需数据,最后通过Review Manager 5.3软件进行Meta分析。结果:最终纳入11项研究,包括1 398例患者,其中有566例接受overlap吻合术的患者和832例接受传统吻合术的患者。结果表明,overlap吻合术和传统吻合术在手术时间(MD=0.63,95%CI=7.22,8.48,P=0.88)、术后首次排气时间(MD=-0.13,95%CI=0.43,0.18,P=0.42)、术后首次进食时间(MD=0.02,95%CI=0.33,0.37,P=0.91)、吻合口漏(OR=1.38,95%CI=0.73,2.63,P=0.32)、术后住院时间(MD=-0.16,95%CI=0.82,0.51,P=0.64)方面无显著差异(均P>0.05)。与传统吻合术相比,overlap吻合术吻合时间较长(MD=5.60,95%CI=0.59,10.62,P=0.03)、吻合口出血发生率较高(OR=2.48,95%CI=1.08,5.69,P=0.03)、术中出血量较少(MD=-6.42,95%CI=10.28,-2.56,P=0.001)、吻合口狭窄发生率较低(OR=0.17,95%CI=0.06,0.46,P=0.000 6)。结论:overlap食管空肠吻合术是一种安全、有效、预后佳的手术方式,有望成为全腹腔镜全胃切除术中食管空肠吻合标准术式。

Objective:To systematically evaluate and compare the safety and effectiveness of esophagojejunostomy and traditional esophagojejunostomy in total laparoscopic total gastrectomy in the treatment of gastric cancer,providing evidence-based medical evidence for clinical practice.Methods:PubMed,Embase,Cochrane Library,Web of Science,CNKI,Wanfang and VIP databases were searched by computer,and the retrieval time was up to December 2021.Relevant literatures were obtained,and eligible studies were gradually screened and included.Cochrane ROB bias risk assessment tool and NOS scale were used to evaluate the quality of the articles,and required data were extracted from high-quality literatures.Finally,meta-analysis was performed using Review Manager 5.3 software.Results:Eleven studies were finally included,including 1398 patients,including 566 patients receiving overlap anastomosis and 832 patients receiving traditional anastomosis.The results show that overlap anastomosis and traditional anastomosis had the advantages of operation time(MD=0.63,95%CI=7.22,8.48,P=0.88),postoperative first exhaust time(MD=−0.13,95%CI=0.43,0.18,P=0.42),postoperative first feeding time(MD=0.02,95%CI=0.33,0.37,P=0.91),anastomotic leakage(OR=1.38,95%CI=0.73,2.63,P=0.32),and postoperative hospital stay(MD=−0.16,95%CI=0.82,0.51,P=0.64)had no significant differences(all P>0.05).Compared with traditional anastomosis,overlap anastomosis had longer anastomosis time(MD=5.60,95%CI=0.59,10.62,P=0.03),higher incidence of anastomotic bleeding(OR=2.48,95%CI=1.08,5.69,P=0.03),less intraoperative bleeding(MD=−6.42,MD=−6.42,OR=2.48,95%CI=1.08,P=0.03).95%CI=10.28,−2.56,P=0.001)and anastomotic stenosis(OR=0.17,95%CI=0.06,0.46,P=0.0006).Conclusion:Overlap esophagojejunostomy is a safe,effective and prognostic surgical method,and is expected to become the standard esophagojejunostomy in total laparoscopic total gastrectomy.
