Comparison of two emergency cervical cerclage techniques in twin pregnancies: A retrospective cohort study matched with cervical dilation. Int J Gynaecol Obstet 2024; 164:1036-1046. [PMID: 37712448 DOI: 10.1002/ijgo.15081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 08/05/2023] [Accepted: 08/17/2023] [Indexed: 09/16/2023]
Abstract
OBJECTIVES This retrospective cohort study aimed to assess the efficacy of emergency cervical cerclage (ECC) performed with the combined McDonald-Shirodkar technique in twin pregnancies between 18 and 26 weeks of pregnancy with painless cervical dilation 1 to 6 cm. METHODS A retrospective cohort study matched with the degree of cervical dilation was conducted. The study group (case group) included women with twin pregnancies undergoing combined McDonald-Shirodkar approach with cervical dilation ≥1 cm between 18 to 26 weeks of gestation at four institutions, from December 2015 to December 2022. To minimize confounding factors, we elucidated the causality structure using a directed acyclic graph and performed 1:1 case-control matching. A control group underwent the McDonald approach. The primary outcome was gestational age (GA) at delivery. The secondary outcomes were pregnancy latency; the rates of spontaneous preterm birth at <28, <30, <32, and <34 weeks; and neonatal outcomes. Additional subanalysis was performed by dividing the patients into two subgroups of women with cervical dilation ≥3 cm and <3 cm. RESULTS A total of 84 twin pregnancies were managed with either the combined McDonald-Shirodkar approach (case group: n = 42) or the McDonald approach (control group: n = 42). Demographic characteristics were not significantly different in the two groups (P > 0.05). After adjusting for confounders that were represented by a directed acyclic graph, median GA at delivery was significantly higher (30.5 vs 27 weeks; Bate: 3.40 [95% confidence interval (CI), 2.13-4.67], P < 0.001) and median pregnancy latency was significantly longer (56 vs 28 days; Bate: 24.04 [95% CI, 13.31-34.78], P < 0.001) in the case group compared with the control group. Rates of spontaneous preterm birth at <28, <30, <32, and <34 weeks were significantly lower in the case group than in the control group. For neonatal outcomes, there was higher birth weight (1543.75 vs 980 g; Bate: 420.08 [95% CI, 192.18-647.98], P < 0.001) and significantly lower overall perinatal mortality (7.1% vs 31%; adjusted odds ratio, 0.16 [95% CI, 0.04-0.70], P = 0.014) in the case group compared with the control group. When cervical dilation was ≥3 cm, the combined McDonald-Shirodkar procedure can significantly reduce perinatal mortality (8.3% vs 46.7%; adjusted odds ratio, 0.09 [95% CI, 0.01-0.77], P = 0.028), significantly decrease the risk of delivery at <28 and <30 weeks, and prolong GA at delivery and pregnancy latency compared with the McDonald procedure. CONCLUSIONS ECC performed with the combined McDonald-Shirodkar procedure in women with twin pregnancies who have cervical dilation 1 to 6 cm in midtrimester pregnancy may reduce the rate of spontaneous preterm birth and improve perinatal and neonatal outcomes compared with the McDonald procedure, especially for twin pregnancies in women with cervical dilation of 3 to 6 cm and prolapsed membranes.

Abstract
OBJECTIVES To estimate clinical effects of emergency cervical cerclage in twin pregnancies with cervical dilation ≥1.0 cm in mid-trimester of gestation and to identify risk factors after cerclage. METHODS This retrospective cohort study included 99 twin pregnancies with cervical dilation ≥1cm in the mid-trimester of gestation at three institutions, from December 2015 through December 2021. The cases were treated with emergency cervical cerclage (52 cases) or expectant management (47 cases). Compare the pregnancy and neonatal outcomes of the two groups. Multiple logistic regression analysis was used to determine the independent risk factors associated with cerclage. RESULTS Cerclage placement was associated with significantly longer gestation age and prolongation of the gestational latency (p < .05). In the cases, compared to expectant treatments, spontaneous preterm birth (sPTB) at <26, <28, <30, <32 weeks was significantly less frequent (p < .05). Pre-operation WBC > 11.55 × 109/L, CRP > 10.1 and cervical dilation >3.5 cm were found to be independent risk factors for delivery 28 weeks after cerclage. CONCLUSIONS Cervical cerclage in twin pregnancies with cervical dilation ≥1.0 cm in mid-trimester of gestation may prolong pregnancy and gestation age, and improve pregnancy and neonatal outcomes compared with expectant management. The strongest predictor of sPTB before 28 weeks after ECC were pre-operation WBC >11.55 × 109/L, CRP > 10.1 and cervical dilation >3.5 cm.

Abstract
The present study aimed to evaluate the perinatal outcomes and influencing factors in twin pregnancies undergoing emergency cervical cerclage. The present retrospective cohort study included clinical data that were recorded between January 2015 and December 2021 at The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University (China). The study included data from 103 pregnancies (26 twin and 77 singleton pregnancies) that underwent emergency cerclage and 17 twin pregnancies that underwent expectant treatment. The median gestational age of twin emergency cerclage was significantly lower than that of singleton emergency cerclage, but higher than that of expectant treatment (28.5, 34.0 and 24.0 weeks, respectively). The median interval to delivery of twin emergency cerclage was significantly lower than that of singleton emergency cerclage, but significantly higher than that of expectantly treated twin pregnancies (37.0, 78.0 and 7.0 days, respectively).IMPACT STATEMENTWhat is already known on this subject? An important cause of premature birth is cervical insufficiency. Cervical cerclage extends the gestational period of women with cervical insufficiency. According to 2019 SOGC's No. 373-Cervical Insufficiency and Cervical Cerclage, both twin and single pregnancies benefit from emergency cerclage. However, there is minimal information about the pregnancy outcomes of emergency cerclage in twin pregnancies.What the results of this study add? This study shows that the outcomes of pregnancy in twin pregnancies undergoing emergency cerclage were better than that of expectant treatment but worse than that in singleton pregnancies undergoing emergency cerclage.What the implications are of these findings for clinical practice and/or further research? In this study, pregnant women with cervical insufficiency in twin pregnancies can benefit from emergency cerclage, we should treat those pregnant women as early as possible.

The efficacy of emergency cervical cerclage in singleton and twin pregnancies: a systematic review with meta-analysis. Am J Obstet Gynecol MFM 2023; 5:100971. [PMID: 37084870 DOI: 10.1016/j.ajogmf.2023.100971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 03/31/2023] [Accepted: 04/09/2023] [Indexed: 04/23/2023]
Abstract
OBJECTIVE An emergency (rescue) cervical cerclage can be offered to pregnant women presenting with dilatation and prolapsed membranes in the second trimester of pregnancy because of cervical insufficiency. This study aimed to investigate the effectiveness of an emergency cerclage in both singleton and twin pregnancies in the prevention of extreme premature birth. DATA SOURCES We performed a systematic literature search in PubMed and Embase from inception to June 2022 for transvaginal cervical emergency cerclages. STUDY ELIGIBILITY CRITERIA All studies on transvaginal cervical emergency cerclages with at least 5 patients and reporting survival were included. METHODS Included studies were assessed for quality and risk of bias with an adjusted Quality In Prognosis Studies tool. Random-effects meta-analyses and meta-regressions were performed for the primary outcome: survival. RESULTS Our search yielded 96 studies, incorporating 3239 women, including 14 studies with an expectant management control group, incorporating 746 women. Overall survival after cervical emergency cerclage was 74%, with a fetal survival of 88% and neonatal survival of 90%. Singleton and twin pregnancies showed similar survival, with a pregnancy prolongation of 52 and 37 days and a gestational age at delivery of 30 and 28 weeks, respectively. Meta-regression analyses indicated a significant inverse association between mean gestational age at diagnosis and pregnancy prolongation and no association between dilatation or gestational age at diagnosis and gestational age at delivery. Compared with expectant management, emergency cerclage significantly increased overall survival by 43%, fetal survival by 17% and neonatal survival by 22%, along with a significant pregnancy prolongation of 37 days and reduction in delivery at <28 weeks of gestation of 55%. These effects were more profound in singleton pregnancies than in twin pregnancies. CONCLUSION This systematic review indicates that, in pregnancies threatened by extreme premature birth because of cervical insufficiency, emergency cerclage leads to significantly higher survival, accompanied by significant pregnancy prolongation and reduction in delivery at <28 weeks of gestation, compared with expectant management. The mean gestational age at delivery was 30 weeks, independent of dilatation or gestational age at diagnosis. Survival was similar for singleton and twin pregnancies, implying that emergency cerclage should be considered in both.
