目的:通过评估生存优势与安全性,比较肠系膜下动脉(IMA)低位结扎伴D3淋巴结清扫术(LLD3)与高位结扎治疗结直肠癌的临床疗效。方法:系统检索PubMed、Embase、Web of Science、The Cochrane Library及中国生物医学文献数据库(CBM)、CNKI...目的:通过评估生存优势与安全性,比较肠系膜下动脉(IMA)低位结扎伴D3淋巴结清扫术(LLD3)与高位结扎治疗结直肠癌的临床疗效。方法:系统检索PubMed、Embase、Web of Science、The Cochrane Library及中国生物医学文献数据库(CBM)、CNKI、维普、万方中自建库至2019年5月收录的比较LLD3与高位结扎术治疗乙状结肠癌或直肠癌的相关文献。采用Stata 14进行统计分析。结果:共纳入15篇文献,两组IMA根部淋巴结清扫数量及5年生存率、5年无瘤生存率、局部复发率差异均无统计学意义。LLD3组吻合口漏、术后排尿功能障碍发生率均低于高位结扎组(OR=1.69,95%CI=1.29~2.23;OR=2.45,95%CI=1.39~4.33),但LLD3组需要更长的手术时间(WMD=-6.82,95%CI=-12.58^-1.06)。结论:LLD3可获得与高位结扎相近的淋巴结清扫数量、等效的长期生存收益,同时可降低吻合口漏、排尿功能障碍的发生率;具备传统观点中两种标准结扎方式的优势,更适合乙状结肠与直肠癌手术。展开更多
