孕期宫颈环扎术治疗宫颈功能不全的临床疗效分析

目的探讨影响择期孕期宫颈环扎术成功因素。方法将我院2010年1月至2013年6月收治的40例宫颈功能不全的孕妇,在卧床休息及保胎治疗的基础上于妊娠12¹6周行择期宫颈环扎术。结果 40例患者手术过程顺利,术中无并发症。环扎前宫颈长度>15 mm、<20 mm患者成功率86.4%,环扎前长度≤15 mm患者成功率44.4%,成功组术后继发阴道炎比例明显低于失败组,差异有统计学意义(P<0.05)。结论择期妊娠期宫颈环扎术后能使妊娠结局显著改善,宫颈长度及宫颈环扎术后继发阴道炎是影响环扎成功率的主要因素。宫颈长度≤15 mm及易患阴道炎患者可选择孕前腹腔镜或经阴道子宫峡部环扎术。加强感染监控可能提高宫颈环扎成功率。

Analysis of Clinical Efficacy of Cervix cerclage in Pregnant Period with Cervical Incompetence

Objective To investigate the effects of cervix cerclage in pregnant period with cervical incompetence. Methods 40 cases of cervical incompetence during January 2010-June 2013 in our Hospital.They were treated by cervix cerclage at 12-16 weeks of pregnancy on the basis of rest in bed and the treatment of tocolysis. Results The operation were successful and without complication in 40 patients. The successful rate was 86.4%in the patients whose cervix length〉15 mm,〈 20 mm before cerclage and 44.4%in whose cervix length≤15 mm. The ratio of vaginitis after operation is significantly lower in the patients who’s successful in the operation（P〈 0.05）. Conclusion The outcome of pregnancy significantly improved by cervix cerclage in pregnant period. Length of cervix and vaginitis after operation are the main factors that influence the success of operation. To the patients whose cervixlength≤15 mm or with vaginitis, cervix cerclage by laparoscopy or vaginal pre pregnancy is appropriate.Prevention of infection can improve the success rate of cervix cerclage.
