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.

Abstract
OBJECTIVE To compare latency to delivery and perinatal outcomes between twin and singleton pregnancies undergoing physical examination-indicated cerclage. METHODS Retrospective observational study (2007-2017) of women who underwent physical examination-indicated cerclage at the Hospital Clinic of Barcelona. Primary outcomes were latency from cerclage to delivery and gestational age at delivery. Secondary outcomes included: neonatal morbidity and mortality, preterm prelabor rupture of membranes, clinical chorioamnionitis and cerclage displacement. Wilcoxon-test and χ2 test were used to compare continuous and categorical variables. RESULTS Sixty women were included (17 twins and 43 singletons). There were no differences in gestational age at cerclage or presence of bulging membranes between groups. Median (25th;75th percentile) gestational age at delivery was 27.1 (24.5;32.3) weeks in the twin group and 27.6 (25.3;35.3) weeks in the singleton group (P = 0.594). There were no statistically significant differences in latency from cervical cerclage to delivery between the two groups (43 days [21;64] vs. 29 days [16;76], respectively; P = 0.938). There were no differences in neonatal mortality (2/26 [7.7%] vs. 1/33 [3.1%]; P = 0.578) or in composite neonatal morbidity (14 [53.9%] vs. 14 [42.4%]; P = 0.283) between groups, respectively. CONCLUSION These results suggest that physical examination-indicated cerclage placement in twins could prolong latency to delivery similarly to singleton pregnancies.

Abstract
OBJECTIVE To determine the effect of mid-trimester emergency cerclage in women with twin pregnancies with cervical dilation and prolapsed membranes, and to identify risk factors predicting spontaneous preterm birth (sPTB) before 28 weeks, after cerclage. METHODS Retrospective analysis of twin gestations with cervical dilation and prolapsed membranes treated with emergency cerclage or expectant management (2015-2020). The primary outcomes were the rate of sPTB before 28 weeks and the gestational latency. Multiple logistic regression analysis was used to determine the factors associated with sPTB before 28 weeks, after cerclage. RESULTS Ninety-seven women were included, cerclage (n = 58) or no cerclage (n = 39). Cerclage placement was associated with significantly lower incidence of sPTB before 28 weeks of pregnancy (34.5% vs 82.1%) and prolongation of the gestational latency (46.71 ± 27.52 vs 10.95 ± 11.71 days). Positive cervical culture (odds ratio [OR] 10.69, 95% confidence interval [CI] 1.82-62.95), pregnancy duration at diagnosis less than 22 weeks (OR 9.42; 95% CI 1.69-52.69) and cervical dilation at least 4 cm (OR 7.92; 95% CI 1.40-44.71) were found to be independent risk factors for sPTB before 28 weeks, after cerclage. CONCLUSION Emergency cerclage in women with twin pregnancies with cervical dilation and prolapsed membranes was associated with an overall 40% decrease in sPTB before 28 weeks and a prolongation of latency by 5 weeks. The strongest predictor of sPTB before 28 weeks after cerclage was a positive cervical culture.

Abstract
INTRODUCTION To compare the pregnancy outcomes of physical examination-indicated cerclage (PEIC) between twin and singleton pregnancies with acute cervical insufficiency. EVIDENCE ACQUISITION We searched Medline, Ovid, Scopus, EBSCO, ClinicalTrials.gov and the Cochrane Central Register of Controlled Trials from their commencement until Dec 2019 for relevant studies. Patient-level data abstraction and analysis were done by two independent authors. EVIDENCE SYNTHESIS A total of five studies with 786 women were included in the final analysis. The pooled outcomes showed that PEIC was associated with a similar reduction in preterm birth (PTB) at <32 (Risk ratio [RR] 0.93, 95% CI 0.79-1.11, I2=0%, P=0.43), and 28 (RR 1.03, 95% CI 0.82-1.29, I2=0%, P=0.81) weeks of gestation; however, a much higher frequency of PTB was observed at <36 (RR 0.74, 95% CI 0.66-0.83, I2=0%, P<0.000), and 34 (RR 0.80, 95% CI 0.68-0.93, I2=0%, P=0.004) weeks of gestation in twin pregnancies than in singleton pregnancies. No significant differences in perinatal outcomes, including neonatal death (RR 1.03, 95% CI 0.64-1.67, I2=52%, P=0.900), stillbirth (RR 0.73, 95% CI 0.37-1.44, I2=0%, P=0.360), perinatal mortality (RR 0.94, 95% CI 0.65-1.38, P=0.760) and neonatal complications were found between twin and singleton pregnancies. CONCLUSIONS Our meta-analysis indicated that PEIC achieved good perinatal prognosis in both singleton and twin pregnancies. However, because the available evidence is insufficient to attain a strong conclusion, so further high-quality trials are needed to confirm our findings.

Abstract
PURPOSE To compare the pregnancy outcome of emergency cerclage performed in twin and singleton pregnancies. METHODS A retrospective trial was carried out in the Department of Obstetrics and Gynecology, Sir Run Run Shaw Hospital in Zhejiang, China, from January 2013 to December 2018. A total of 89 women with acute cervical incompetence underwent the emergency cerclage. Main outcome measures were gestational age at delivery and the fetal outcome. RESULTS There were 31 twin and 58 singleton pregnancies that underwent emergency cerclage. In singleton pregnancies, gestational age at delivery (31.57 ± 6.11 vs 28.81 ± 4.34, p = 0.016), and prolongation of pregnancy (8.69 ± 6.13 vs 5.41 ± 3.72, p < 0.001) were greater, and the preterm delivery rate before 34 weeks was lower (53.4% vs 80.6%, p = 0.011) compared with twin pregnancies. Fetal weight was greater in singletons than in twins (2377.3 ± 862.1 vs 1630.3 ± 557.6, p < 0.001), but the fetal survival rate was similar. The proportion of twin gestations was significantly higher in the group with preterm delivery before 34 weeks (44.6% vs 18.2%, p = 0.011) and the proportion of previous term delivery was higher in the group with delivery at or after 34 weeks (30.3% vs 12.5%, p = 0.039). The group with preterm delivery before 34 weeks had a significantly larger size of visible membranes at cerclage than the group with delivery at or after 34 weeks (2.23 ± 0.86 vs 1.64 ± 0.80, p = 0.001). In binary logistic regression analysis, twin gestations and a larger size of visible membranes were associated with an increased risk of preterm delivery. CONCLUSION The pregnancy outcome of emergency cerclage appears to have a better prognosis in singleton pregnancies than in twin pregnancies, and twin pregnancy is a risk factor for preterm delivery.

Abstract
OBJECTIVES Acute cervical insufficiency accounts for 10-25 % of all mid-trimester pregnancy losses. However, the definition and description for the degree of acute cervical insufficiency were obscure and different among the many studies. The aim of this study was to suggest a new 4-digit quantification system and to evaluate the outcome according to the new system in women with acute cervical insufficiency. STUDY DESIGN A retrospective cohort study was conducted in patients with acute cervical insufficiency who underwent physical examination indicated cervical cerclage. Acute cervical insufficiency was defined as painless external os dilation with prolapsed and/or visible membranes on speculum examination. The status of fetal membranes was described using two values: 1) size of the prolapsed membrane (P, measured using ultrasound); and 2) size of visible fetal membranes (M, evaluated by speculum examination). The status of cervix was described using two values: 1) dilatation of the narrowest os (O, measured by ultrasound); and 2) functional cervical length (C, measured by ultrasound). The patients were divided into 3 groups as follows: Stage I, patients with visible fetal membranes (M > 0) but with a remaining functional cervix (C > 0) (N = 7); stage II, those with visible fetal membranes (M > 0) and a functional cervical length of 0 but without prolapsed membranes (P = 0) (N = 33); and stage III, those with prolapsed membranes (P > 0) (N = 40). RESULTS 1) Patients who delivered before 34 weeks of gestation had a significantly lower median gestational age at cerclage operation and a significantly higher median P, M, C values than those who delivered at or beyond 34 weeks of gestation(P < 0.01 for gestational age at operation, P and M values; P < 0.05 for C value); 2) The higher the stage based on PMOC quantification system, the greater the risk of preterm delivery before <24, <32, <34, and <37 weeks of gestation (P < 0.001 for all); 3) The neonatal survival rate was 100 % (7/7) for stage I, 93.9 % (31/33) for stage II, and 60 % (24/40) for stage III. CONCLUSION The PMOC system was a simple method to describe the individualized conditions and to predict the risk of preterm births in all spectrums of acute cervical insufficiency.

Abstract
Objectives Pregnant women are more susceptible to certain infections; however, this increased susceptibility is not fully understood. Herein, systems biology approaches were utilized to elucidate how pregnancy modulates tissue-specific host responses to a bacterial product, endotoxin. Methods Pregnant and non-pregnant mice were injected with endotoxin or saline on 16.5 days post coitum (n=8-11 per group). The uterus, cervix, liver, adrenal gland, kidney, lung, and brain were collected 12 h after injection and transcriptomes were measured using microarrays. Heatmaps and principal component analysis were used for visualization. Differentially expressed genes between groups were assessed using linear models that included interaction terms to determine whether the effect of infection differed with pregnancy status. Pathway analysis was conducted to interpret gene expression changes. Results We report herein a multi-organ atlas of the transcript perturbations in pregnant and non-pregnant mice in response to endotoxin. Pregnancy strongly modified the host responses to endotoxin in the uterus, cervix, and liver. In contrast, pregnancy had a milder effect on the host response to endotoxin in the adrenal gland, lung, and kidney. However, pregnancy did not drastically affect the host response to endotoxin in the brain. Conclusions Pregnancy imprints organ-specific host immune responses upon endotoxin exposure. These findings provide insight into the host-response against microbes during pregnancy.

Abstract
PURPOSE This study aimed to evaluate the efficacy of physical examination-indicated cerclage in twin pregnancies and compare it with those that received conservative management. METHODS We used a retrospective cohort study design of asymptomatic twin pregnancies identified with physical examination indications at 14-26 weeks from 2015 through 2019 at Fujian Maternity and Child Health Hospital. The primary outcomes were gestational age (GA) at delivery and the incidence of spontaneous preterm birth (SPTB) at < 34 weeks, < 32 weeks, < 28 weeks, and < 24 weeks. The main secondary outcomes were latency period from diagnosis to delivery, composite neonatal adverse outcome and neonatal survival at discharge. RESULTS Thirty-one women with twin pregnancies were managed with physical examination-indicated cerclage, and another 31 received expectant management. The demographic characteristics of the two groups were not significantly different. GA at delivery was significantly later in the cerclage group than in the controls: 32.53 ± 4.78 vs. 27.53 ± 4.15 weeks, with a mean difference of 5.00 weeks [95% confidence interval (CI), 2.73-7.28]. There were significant decreases in the incidence of spontaneous preterm birth (SPTB) at < 34 weeks, < 32 weeks, < 28 weeks, and < 24 weeks in the cerclage group. The interval from diagnosis to delivery was increased with cerclage by a mean difference of 4.37 weeks (95% CI, 1.96-7.06). Regarding neonatal outcome, the perinatal mortality rate in the cerclage group was significantly reduced compared to that in the control group [8/62 (12.9%) vs. 26/62 (41.9%); P < 0001]. Likewise, the neonatal intensive care unit (NICU) admissions, length of stay in the NICU, and composite adverse neonatal outcome in the cerclage group were significantly reduced. CONCLUSION Physical examination-indicated cerclage was associated with significantly later GA at delivery, longer latency period from diagnosis to delivery, decreased incidence of SPTB at any given GA, and improved perinatal outcome compared with the corresponding measures in controls treated conservatively.

Oh KJ, Romero R, Park JY, Lee J, Conde-Agudelo A, Hong JS, Yoon BH. Evidence that antibiotic administration is effective in the treatment of a subset of patients with intra-amniotic infection/inflammation presenting with cervical insufficiency. Am J Obstet Gynecol 2019; 221:140.e1-140.e18. [PMID: 30928565 DOI: 10.1016/j.ajog.2019.03.017] [Citation(s) in RCA: 82] [Impact Index Per Article: 16.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2018] [Revised: 03/13/2019] [Accepted: 03/21/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND Cervical insufficiency is a risk factor for spontaneous midtrimester abortion or early preterm birth. Intra-amniotic infection has been reported in 8-52% of such patients and intra-amniotic inflammation in 81%. Some professional organizations have recommended perioperative antibiotic treatment when emergency cervical cerclage is performed. The use of prophylactic antibiotics is predicated largely on the basis that they reduce the rate of complications during the course of vaginal surgery. However, it is possible that antibiotic administration can also eradicate intra-amniotic infection/inflammation and improve pregnancy outcome. OBJECTIVE To describe the outcome of antibiotic treatment in patients with cervical insufficiency and intra-amniotic infection/inflammation. STUDY DESIGN The study population consisted of 22 women who met the following criteria: (1) singleton pregnancy; (2) painless cervical dilatation of >1 cm between 16.0 and 27.9 weeks of gestation; (3) intact membranes and absence of uterine contractions; (4) transabdominal amniocentesis performed for the evaluation of the microbiologic and inflammatory status of the amniotic cavity; (5) presence of intra-amniotic infection/inflammation; and (6) antibiotic treatment (regimen consisted of ceftriaxone, clarithromycin, and metronidazole). Amniotic fluid was cultured for aerobic and anaerobic bacteria and genital mycoplasmas, and polymerase chain reaction for Ureaplasma spp. was performed. Intra-amniotic infection was defined as a positive amniotic fluid culture for microorganisms or a positive polymerase chain reaction for Ureaplasma spp., and intra-amniotic inflammation was suspected when there was an elevated amniotic fluid white blood cell count (≥19 cells/mm3) or a positive rapid test for metalloproteinase-8 (sensitivity 10 ng/mL). For the purpose of this study, the "gold standard" for diagnosis of intra-amniotic inflammation was an elevated interleukin-6 concentration (>2.6 ng/mL) using an enzyme-linked immunosorbent assay. The results of amniotic fluid interleukin-6 were not available to managing clinicians. Follow-up amniocentesis was routinely offered to monitor the microbiologic and inflammatory status of the amniotic cavity and fetal lung maturity. Treatment success was defined as resolution of intra-amniotic infection/inflammation or delivery ≥34 weeks of gestation. RESULTS Of 22 patients with cervical insufficiency and intra-amniotic infection/inflammation, 3 (14%) had microorganisms in the amniotic fluid. Of the 22 patients, 6 (27%) delivered within 1 week of amniocentesis and the remaining 16 (73%) delivered more than 1 week after the diagnostic procedure. Among these, 12 had a repeat amniocentesis to assess the microbial and inflammatory status of the amniotic cavity; in 75% (9/12), there was objective evidence of resolution of intra-amniotic inflammation or intra-amniotic infection demonstrated by analysis of amniotic fluid at the time of the repeat amniocentesis. Of the 4 patients who did not have a follow-up amniocentesis, all delivered ≥34 weeks, 2 of them at term; thus, treatment success occurred in 59% (13/22) of cases. CONCLUSION In patients with cervical insufficiency and intra-amniotic infection/inflammation, administration of antibiotics (ceftriaxone, clarithromycin, and metronidazole) was followed by resolution of the intra-amniotic inflammatory process or intra-amniotic infection in 75% of patients and was associated with treatment success in about 60% of cases.

Abstract
Cervical cerclage in women with twin pregnancy is not routinely indicated but appears to be beneficial in subjects with a history of preterm birth or very short cervix or dilated cervix. There is a paucity of literature data regarding transabdominal or laparoscopic cervical cerclage (LCC) in twin pregnancy. It is uncertain whether LCC is more effective than transvaginal cerclage. Our own experience of 24 cases of LCC in twin pregnancy showed encouraging results. Further, well-planned studies are required to answer whether, when, and how cervical cerclage should be performed in women with twin pregnancy.

Cerclage for women with twin pregnancies: a systematic review and metaanalysis. Am J Obstet Gynecol 2019; 220:543-557.e1. [PMID: 30527942 DOI: 10.1016/j.ajog.2018.11.1105] [Citation(s) in RCA: 56] [Impact Index Per Article: 11.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2018] [Revised: 11/21/2018] [Accepted: 11/24/2018] [Indexed: 01/11/2023]
Abstract
OBJECTIVE DATA This study was conducted to estimate whether cerclage could extend the prolongation of pregnancy, reduce the risk of preterm birth, and improve perinatal outcomes in women with twin pregnancies. STUDY ELIGIBILITY CRITERIA We included randomized controlled trials and cohort studies comparing the efficacy of cerclage with no cerclage for women with twin pregnancies. STUDY APPRAISAL AND SYNTHESIS METHODS The following databases were searched for all published studies that compared cerclage placement with expectant management in twin pregnancies from inception to July 2018: Medline, EMBASE, Scopus, ClinicalTrials.gov, Web of Science, and Cochrane Library. Each report was reviewed for inclusion or exclusion standard, and data extraction was performed by 2 authors independently. RESULTS A total of 16 studies with 1211 women that met the inclusion criteria were included in the final analysis. Our outcomes indicated that cerclage placement for twin pregnancies with a cervical length of <15 mm was associated with significant prolongation of pregnancy by a mean difference of 3.89 weeks of gestation (95% confidence interval, 2.19-5.59; P=.000; I2=0%) and a reduction of preterm birth at <37 weeks of gestation (risk ratio, 0.86; 95% confidence interval, 0.74-0.99; P=.040; I2=0%), <34 weeks of gestation (risk ratio, 0.57; 95% confidence interval, 0.43-0.75; P=.000; I2=0%) and <32 weeks of gestation (risk ratio, 0.61; 95% confidence interval, 0.41-0.90; P=.010; I2=0%), compared with those pregnancies in the control group. For women with a dilated cervix of >10 mm, cerclage placement was associated with significant prolongation of pregnancy by a mean difference of 6.78 weeks of gestation (95% confidence interval, 5.32-8.24; P=.000; I2=0%); a reduction of preterm birth at <34 weeks of gestation (risk ratio, 0.56; 95% confidence interval, 0.45-0.69; P=.000; I2=28%), <32 weeks of gestation (risk ratio, 0.50; 95% confidence interval, 0.38-0.65; P=.000; I2=14%), <28 weeks of gestation (risk ratio, 0.41; 95% confidence interval, 0.20-0.85; P=.030; I2=80%), and <24 weeks of gestation (risk ratio, 0.35; 95% confidence interval, 0.18-0.67; P=.001; I2=24%), and improvement of perinatal outcomes compared with those in the control group. However, for twin pregnancies with a normal cervical length (eg, cerclage for an indication for women with a history of preterm birth or twin alone), the efficacy of cerclage placement was less certain because of the limited data. CONCLUSION Our metaanalysis indicates that cerclage placement is beneficial for the reduction of preterm birth and the prolongation of pregnancy in twin pregnancies with a cervical length of <15 mm or dilated cervix of >10 mm. However, the benefit of history-indicated or twin alone-indicated cerclage is less certain in twin pregnancies with normal cervical length according to current literature. Further high-quality studies were needed to confirm the findings.
