目的:通过Meta分析综合评价临时卵巢悬吊术是否能减少子宫内膜异位症(EMs)患者腹腔镜术后的卵巢粘连。方法:检索PUBMED、MEDLINE、EMBASE、the ISI Web of Science、Ovid、Cochrane Library、中国知网(CNKI)、万方全文数据库、维普中文...目的:通过Meta分析综合评价临时卵巢悬吊术是否能减少子宫内膜异位症(EMs)患者腹腔镜术后的卵巢粘连。方法:检索PUBMED、MEDLINE、EMBASE、the ISI Web of Science、Ovid、Cochrane Library、中国知网(CNKI)、万方全文数据库、维普中文科技期刊数据库、中国生物医学文献数据库、中国期刊全文数据库和Google学术搜索等,并辅以手工检索。检索时间截至2017年12月,收集关于临时卵巢悬吊术预防腹腔镜手术治疗EMs术后卵巢粘连的随机对照试验(RCT)。由2名研究者按Cochrane系统评价方法提取数据进行Meta分析。结果:共纳入4篇RCT,共计302例患者。结果显示:临时卵巢悬吊术能降低EMs患者腹腔镜治疗后卵巢粘连的发生(RR=0.75,95%CI:0.64~0.87),可能有效缓解EMs患者腹腔镜术后大便困难(RR=-0.30,95%CI:-0.58^-0.02),但并不一定能缓解患者痛经(RR=-0.75,95%CI:-1.92~0.41)、慢性盆腔疼痛(RR=-0.77,95%CI:-1.88~0.35)、性交困难(RR=1.25,95%CI:-0.86~3.37)及尿痛(RR=-1.51,95%CI:-4.22~1.20)。结论:运用临时卵巢悬吊术能减少腹腔镜治疗EMs患者术后卵巢粘连的发生,改善患者大便困难的症状,一定程度提高患者生活质量。展开更多
