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%,P<0.05);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(P>0.05)。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。
Objective: To evaluate the efficacy of multiple cervical cerclage in the treatment of cervical incompetence. Methods: The clinical data of 51 cases with single or multiple cervical cerclage were retrospectively analyzed. Results: (1) The surgical success rate of multiple cervical cerclage group (A group) was significantly higher than that of single cervical cerclage group (78.6% vs 38.5%, P <0.05) (129.9 ± 49.9 vs 55.7 ± 45.6) d, (2527.3 + 916.3 vs 1289.2 + 1238.8) g, and the number of days of termination of pregnancy, prolonged days of gestation, and neonatal weight increased significantly in group A (248.0 ± 26.9 vs 186.6 ± 54.7) d , P <0.05. (2) There was no significant difference between the success rate of postoperative hospitalization and postoperative discharge (P> 0.05). Conclusion: The curative effect of multiple cervical cerclage is better than that of single cervical cerclage, which can significantly prolong gestational age and increase the weight of newborn. Hospitalization after operation can not increase the success rate of operation.
