Retrospective analysis of pregnancy outcome of 82 patients undergoing laparoscopic cervical cerclage before IVF-ET

Objective:To investigate the effects of the pre-pregnant laparoscopic cervical cerclage(LTCC)on patients with cervical incompetence(CI),and to compare the pregnancy outcomes between cleavage-stage embryo transfers and blastocyst transfers respectively.Methods:The data of infertile patients who was diagnosed with cervical incompetence before IVF-ET from January 2017 to March 2019 were analyzed retrospectively.According to the different types of embryos transferred,they were divided into cleavage stage embryo group(n=20)and blastocyst group(n=62).The postoperative pregnancy outcomes of patients were compared between the two groups for live birth rate,HCG positive rate,clinical pregnancy rate,embryo implantation rate,ectopic pregnancy rate,miscarriage rate,premature birth rate,gestational week of delivery,and offspring births status(including newborn births weight,sex ratio and birth defects).Results:Eighty two patients were included.The average termination time of previous pregnancy was(20.68±3.44)gestational week.After pre-pregnant LTCC,the average delivery time of cleavage-stage embryo transfer and blastocyst transfer were(37.70±1.42)weeks and(38.11±1.07)weeks respectively.The live birth rate of cleavage-stage embryo transfer and blastocyst transfer was 50%and 45.16%respectively,and there was no significant difference(P>0.05).The HCG positive rate(74.19%vs.50%)and abortion rate(33.33%vs.0.00%)of blastocyst transfer were significantly higher than cleavage-stage embryo transfer(P<0.05).There were no significant differences in clinical pregnancy rate,implantation rate,ectopic pregnancy rate,preterm birth rate and average delivery week between the two groups(P>0.05).In addition,there were no significant differences in neonate weight,sex ratio and birth defects rate between the two groups(P>0.05).Conclusions:Pre-pregnant LTCC improves reproductive outcomes of patients with cervical incompetence,and final live birth rate were similar between cleavage-stage embryo transfer and blastocyst transfer.
