多次宫颈环扎术治疗宫颈机能不全的疗效观察

目的:评价多次宫颈环扎术治疗宫颈机能不全的疗效。方法:回顾性分析行单次或多次宫颈环扎术51例的临床资料。结果:(1)多次宫颈环扎术组(A组)的手术成功率明显高于单次宫颈环扎术组(B组)(78.6%vs 38.5%,P0.05);与B组相比,A组终止妊娠的天数、延长妊娠天数及新生儿体重明显增加(248.0±26.9 vs 186.6±54.7)d;(129.9±49.9 vs 55.7±45.6)d;(2527.3+916.3 vs 1289.2+1238.8)g,P均0.05。(2)术后住院组的手术成功率与术后出院组无明显差异(P0.05)。结论:多次宫颈环扎术的疗效优于单次宫颈环扎术,能明显延长孕周及增加新生儿体重:术后住院并不能增加手术成功率。

Effect Observation of Repeatedly Cervical Cerclage in Treatment of Cervical Incompetence

Objective： TO evaluate the effect of repeatedly cervical cerelage in treatment of cervical incompetence. Methods： The clinical data of 51 women treated with cervical cerclage for cervical incompetence were analyzed retrospectively. Results： （1）The successful rate of the group with more than twice cervical cerclages （group A） was more higher than that in the group with only once （group B）（78.6% vs 38.5%,P 〈 0.05）. Longer gestational days, prolonger gestational days and heavier neonate birth weight in group A than those in group B （248.0±26.9 vs 186.6± 54.7d, 129.9±49.9 vs 55.7±45.6d,2527.3±916.3 vs 1289.2±1238.8g, all P 〈 0.05）. （2）The success rate was no significant differences between the in or out hospital group after cerclage（P 〉 0.05）. Conclusions： Repeatedly cervical cerclage is better than once, it can prolong gestational days and increase neonate birth weight. Hospitalization cannot increase the successful rate of operation.
