Cervical cerclage: An evolving evidence base.

Cervical cerclage is an established intervention for the management of pregnancies at high risk of preterm birth. Although studies exist to support its use in certain situations, particularly in singleton pregnancies, many questions such as adjunct therapies and efficacy in specific subgroups of high-risk women have not been fully elucidated. This review will assess the current evidence as well as areas where there is currently a paucity of data and an urgent requirement for further research.

Prevention of intrauterine balloon displacement in patients with postpartum hemorrhage: A narrative review.

Postpartum hemorrhage (PPH) remains a significant complication of pregnancy globally, with uterine atony accounting for the great majority of cases. Second-line hemostatic strategies such as uterine balloon tamponade play a crucial role in managing refractory hemorrhage. Despite its effectiveness, the phenomenon of balloon displacement poses a challenge to PPH management, often leading to treatment failure. Various techniques have been proposed to address this issue, including vaginal packing, cervical cerclage, fixation to the abdominal wall, holding the cervix with ring forceps, and suspending the balloon with cervical sutures. Each method has its advantages and limitations, influencing its suitability in different clinical scenarios. Understanding these techniques may be useful to optimize and improve the management of PPH and maternal outcomes. This review provides a comprehensive summary of these strategies, their mechanisms, and their clinical implications, aiming to guide healthcare providers in choosing the most appropriate approach for individual cases of PPH.

Cervical cerclage vs cervical pessary in women with cervical insufficiency: A multicentric, open-label, randomised, controlled pilot trial [the CEPEIC trial]

ObjectiveCervical insufficiency accounts for 8 % of preterm births. Pessary and cerclage are considered preventive approaches for preterm birth. These interventions were compared in terms of reducing the prematurity rate in women with previous preterm birth, due to cervical insufficiency or due to having a short cervix in their current pregnancy. MethodsThis was a prospective, multicentric, open-label, randomised, pilot, controlled trial. Participants were women with singleton pregnancies who had previous preterm birth caused by cervical insufficiency or previous preterm birth and a short cervix [≤ 25 mm] in their current pregnancy. Women were randomised [1:1] to either cerclage or pessary. The primary outcome was to assess the feasibility of a trial on cervical pessary vs. cerclage to prevent preterm birth before 34 weeks in women with cervical insufficiency. As a secondary outcome, we studied the morbidity rate of the pessary versus the cerclage in women with cervical insufficiency and assessed the financial impact of using both devices in these women. The sample size was calculated based on the estimated population that we could potentially recruit: 60 women, 30 for each group, to ascertain whether the rate of preterm birth < 34 weeks of gestation may be reduced from 34 % to at least 27 % in the pessary group, as in the results obtained with the cerclage. ResultsNo significant differences in preterm birth < 34 weeks of gestation were observed in our study, although it was underpowered to detect these differences [the relative risk [RR] of PB < 34 weeks of gestation was 0.8 [95 % CI: 0.31–2.09, p = 0.888]. The rates of obstetric and perinatal complications were similar for both devices [15 cases in both groups, 50 % of cases [RR; 0.6–1.68; p = 1]. Cervical pessary had fewer secondary effects than the cerclage [less bleeding at insertion in the pessary group compared with cerclage, 1 case vs 14 cases, p < 0.001; less pain at removal in the pessary group compared with cerclage, 14 vs 22 cases. p = 0.042 and less bleeding, 2 cases vs. 10 cases, p = 0.027]. ConclusionsPessary does not seem less effective than cerclage, although these findings need to be confirmed in a larger randomised controlled trial. Pessary had fewer secondary effects than cerclage both at insertion and removal. SinopsisCervical pessary does not seem to be less effective than cerclage. Cervical pessary had fewer secondary effects than cerclage.

Laparoscopic Transabdominal Needle-free Emergency Cerclage in the Early Second Trimester of Pregnancy after Failed Transvaginal Cerclage: Two Case Reports and a Review of the Literature.

The aim of the study was to describe the preventive option and safety of laparoscopic transabdominal emergency cerclage in pregnant women with advanced cervical shortening after failed vaginal cerclage or in whom vaginal cerclage is no longer possible. Laparoscopic isthmo-cervical emergency cerclage was carried out in two patients at 13+0 and 15+5 weeks of gestation (GW) respectively. Both patients had cervical shortening and it was no longer possible to expose the cervix after conization or re-conization. The attempts to carry out transvaginal cerclage were unsuccessful. The technical aspects, feasibility, safety, and pregnancy outcomes after laparoscopic transabdominal cerclage are presented here, based on two case reports. The cerclages were placed after blunt dissection of the uterine vessels and careful introduction of a KELLY forceps through the avascular space between the ascending and descending branches of the uterine vessels without using a needle. The operating times were 93 and 134 minutes (min), respectively. The estimated blood loss during the procedure was less than 50ml and neither perioperative nor postoperative complications occurred. The subsequent course of both pregnancies was uneventful and fetal development in both cases was normal. In the first case, the baby was delivered by secondary cesarean section following premature rupture of membranes in week 35+4 of gestation. The baby had a birthweight of 2786g, APGAR scores of 8/9/10 and an umbilical cord arterial pH of 7.36. In the second case, delivery was by primary cesarean section in week 39+5 of gestation. The infant had a birth weight of 4160g, APGAR scores of 5/9/10 and an umbilical cord arterial pH of 7.20. Laparoscopic transabdominal cerclage is a safe and effective treatment option, even early in the second trimester of pregnancy, for patients in whom transvaginal cerclage is no longer possible due to anatomical factors. The method is technically very feasible and is associated with positive obstetric outcomes. The overall risk of perioperative complications is within acceptable limits.

Emergency cerclage: Neonatal outcomes and evaluation of prognostic scores − A decade of experience at a tertiary center

ObjectivesEmergency cervical cerclage is a high-risk surgical procedure associated with maternal and fetal risks, including preterm birth. Authors have developed scores to try to predict the probability of success following emergency cerclage, but these tools have yet to be externally validated.Our main objective was to assess the preterm birth rate before 32 weeks following emergency cerclage. Secondary objectives included assessing perinatal outcomes and the predictive validity of two published scores in our setting. We hypothesized that predictive scores, such as Fuchs and Kokia scores, may not perform optimally in our population due to variability in clinical and biological characteristics that influence eligibility for cerclage across different settings. Study designWe conducted a retrospective, monocentric study in a tertiary maternity hospital. All patients who underwent emergency cerclage between January 1st, 2010, and December 31st, 2021, were included. The main outcome was preterm birth rate before 32 weeks. Secondary outcomes were need for maternal hospitalization after initial hospitalization for cerclage, preterm premature rupture of membrane, and perinatal death. The rate of preterm birth before 32 weeks and adverse perinatal outcomes were estimated. To assess the predictive validity of Fuchs’ score in our population, we performed a multivariable logistic regression model including the score’s variables and constructed receiver operating characteristic (ROC) curve. To assess the validity of Kokia’s score in our population, we studied the correlation between the initial score and gestational age at delivery using Pearson’s correlation coefficient. ResultsOur population was composed of 64 women who underwent an emergency cerclage. The median gestational age at delivery was 30.6 weeks (IQR (24.2; 37.6)). The preterm birth rate before 32 weeks was 54.7 %. The rate of perinatal death was 30.7 %. There were no statistical differences between the patients delivered before and after 32 weeks. The multivariable logistic regression model showed that none of the variables of Fuchs’s score were significantly associated with preterm birth risk in our population. The AUC of the ROC curve using Fuchs’ score was 0.63. There was a minor yet significant correlation between Kokia’s score and gestational age at delivery (r = 0.26 – p = 0.04). ConclusionsOur study underscores the persistent risks associated with cervical insufficiency, including very preterm birth. It highlights the variability in performance of predictive scores across different populations, underscoring the need for external validation in diverse clinical settings.

Effect Of Cerclage Suture Type On Pregnancy And Newborn Results: Mersylene Suture Versus Prolene Suture

Purpose: The aim of this study is to compare pregnancy and neonatal outcomes according to the type of the suture material used in the transvaginal cerclage operation. Materials and Methods: Patients who underwent transvaginal cervical cerclage due to cervical insufficiency in a tertiary health center between 2020 and 2024 were evaluated retrospectively. Demographic data regarding cerclage indications (ultrasound-based, prophylactic or physical examination-based), number of weeks of gestation in cerclage, cerclage suture type (prolene, mersilen), gestational week at cerclage insertion and delivery, routes of delivery were recorded. In addition, birth weight, 1st and 5th minute APGAR scores, and neonatal intensive care unit (NICU) requirements were recorded as neonatal parameters. Patients were divided into two groups according to cerclage suture type (mersilene or prolene) and maternal, newborn and pregnancy outcomes were compared between these groups. Results: Comparison of the groups in terms of age, gravidity, parity, number of miscarriages and BMI revealed significantly higher mean gravidity in group 1 compared to group 2 (P0.05). No difference was determined with regard to gestational week at cerclage application, cervical length, cervical dilatation just before cerclage insertion, gestational age at cerclage removal and delivery and birth weight (p&gt;0.05). Groups were comparable in terms of subgroups established according to their numbr number of previous deliveries (p&gt;0.05). Groups were comparable in terms of indications for cerclage insertion (p&gt;0.05). Cesarean delivery rate was 40 % in group 1 while it was 43.6 % in groups 2, no statistical difference was determined in terms of rate of cesarean delivery (p&gt;0.05). Similar number of newborns needed NICU admission between the two groups following delivery (17.5% versus 17.9 %p&gt;0.05). Mean APGAR scores at 1st (6.8 versus 7.4) and 5 th (7.8 versus 8.3) min were comparable between the groups (p&gt;0.05) Conclusion: Although mersilen stitch is commonly preferred, data analysis revealed similar results with prolene stitch in terms of maternal and neonatal outcomes.

Exploring the Limits of Rescue Cerclage by Preoperative Sonography: Imaging Contribution and Therapeutic Considerations

Abstract Cervical insufficiency poses risks for premature birth and neonatal outcomes. Preoperative sonography aids in the diagnosis and therapeutic considerations. Cervical cerclage is effective but carries risks. In our case series, 8 cases failed to complete emergent cerclage, leading to adverse outcomes. Analysis of preoperative images revealed thicker cervixes and cervical strictures may affect the surgical outcomes. Larger studies are needed to determine the reliable cutoff values. Preoperative assessment is crucial to inform treatment decisions.

Transvaginal cervical cerclage – How well do surgeons assess their own procedures?

IntroductionIn women with cervical incompetence, transvaginal cerclage may help prevent preterm birth. However, training for this procedure poses challenges due to the low number of cases and difficulties in visualizing the operative field. Furthermore, the objective criteria for a successful cerclage procedure are not well-described. Quality assessment relies heavily on self-assessment rather than objective criteria and feedback. To address this issue, training on a simulator may offer a solution. We aimed to objectively assess surgical performance and compare it to the self-assessed performance in transvaginal cerclage procedures. Materials and methodsDuring the Nordic Federation of Obstetrics and Gynecology (NFOG) congress in 2023, surgeons proficient in transvaginal cerclage procedures performed a transvaginal cerclage on a simulator. To compare the observed and self-assessed outcomes we obtained measurements on the cerclage height and number of bites from the detachable cervix, and from computed tomography scans we analyzed suture bite depth, reduction of cervix surface area, and whether cerclages had perforated the cervical canal. The same outcomes were self-assessed by each participant after the cerclage procedure. We visualized the continuous paired data in a Bland-Altman plot and compared these data with a paired t-test. Paired binary data was analyzed using McNemars test. Results29 participants from eight different nationalities performed one transvaginal cerclage each. The mean height of the cerclage was 26.8 mm (SD 9 mm) and mean depth was 6.5 mm (SD 1.9 mm) across a mean of 4.1 (SD 0.8) bites. The mean reduction of the cervix surface area was 7.6 % (SD 5.9 %). Two sutures perforated the cervical canal. The participants significantly underestimated the height of their cerclage with a mean difference of 6.0 mm (95 % CI 2.1–9.9), (p 0.002), between the observed and the self-assessed height, but otherwise revealed good self-assessment of their performed procedure. ConclusionsOverall, the experienced cerclage surgeons showed a genuine insight into their surgical performance of a transvaginal cerclage. These results could warrant development of a procedural guidelines with objective measures, now reassured that surgeons are capable of self-assessing their procedures.

Predictors of preterm birth following emergency and ultrasound-indicated cervical cerclage: A retrospective study on 136 singleton pregnancies

ObjectiveWe aimed to retrospectively evaluate obstetric and neonatal outcomes in patients who underwent ultrasound-indicated and rescue cervical cerclage and to identify predictors for cerclage failure and consequent preterm birth (PTB). Materials and methodsWe conducted a retrospective analysis on singleton pregnancies between 16 and 27 weeks of gestation who presented with a transvaginal sonographic cervical length (TVS-CL) <25 mm and a previous PTB/second-trimester miscarriage or prolapsed amniotic membranes and/or a TVS-CL <15 mm and underwent cervical cerclage at Mangiagalli Center, Milan, between September 2011 and December 2021. Univariate and multivariate logistic regression analyses were used to identify possible predictive factors of cerclage failure. ResultsDuring the study period, a total of 136 singletons met the inclusion criteria. Overall, 3 % of pregnancies did not reach fetal viability, mostly due to post-cerclage preterm premature rupture of membranes and/or chorioamnionitis. The mean gestational age at delivery was 35.9 ± 4.5 weeks. Neonates were delivered beyond 37 weeks in 63.2 % of cases, between 28 and 37 weeks in 26.5 %, and less than 28 gestational weeks in 10.3 %. At the multivariate analysis, independent risk factors for miscarriage or PTB were cervical length <10 mm (odds ratio, OR 3.44), advanced cervical dilatation (OR 4.76), and in vitro fertilization (OR 4.66). A history of previous miscarriage, premature delivery, and uterine malformations did not increase the risk of post-cerclage delivery before 37 weeks. In the preterm delivery group, 14 % of patients experienced preterm premature rupture of membranes (pPROM) and 10 % had chorioamnionitis, while no case was registered in the term delivery group. A positive vaginal swab at the time of cervical cerclage was not significantly associated with PTB at the multivariate analysis but it emerged as a significant risk factor for both chorioamnionitis (OR 11.03) and pPROM (OR 5.28). ConclusionsUltrasound-indicated and rescue cervical cerclage were effective in prolonging pregnancy, even when placed beyond 24 weeks of gestation. Preoperative cervical length of less than 10 mm, advanced dilatation, and in vitro fertilization are associated with an increased risk of cerclage failure. A positive vaginal swab before cerclage is associated with increased rates of intrauterine infectious-inflammatory processes.

Septic Abortion at 17 Weeks Gestation after Radical Trachelectomy and Transabdominal Cerclage: A Case Report

Septic abortion can lead to severe maternal morbidity and mortality. The management of septic abortion can be complicated by a history of radical trachelectomy and transabdominal cerclage placement. A 33-year-old G1P0 at 17 weeks and 6 days gestation presented in severe septic shock after being diagnosed 6 days prior with previable rupture of membranes at an outside hospital and managed expectantly. History was notable for cervical adenocarcinoma status post radical trachelectomy and transabdominal cerclage placement. Due to uterine occlusion from the cerclage, the patient underwent emergent uterine evacuation via an abdominal approach. The risks and benefits of expectant management of pre-viable rupture of membranes in patients with abdominal cerclage should be weighed very cautiously. Among women with abdominal cerclage for whom uterine evacuation is indicated, a transabdominal approach may be necessary.

Rescue Cervical Cerclage for Previable Birth Prevention: A Comprehensive Review of Indications, Techniques, and Outcomes.

Cervical cerclage is a surgical intervention aimed at preventing previable birth by providing mechanical support to the cervix through the placement of a suture. This procedure is primarily indicated for cases of cervical incompetence, where the cervix is prone to premature dilation and can lead to early miscarriage or preterm birth. This review seeks to comprehensively analyze rescue cervical cerclage (RCC), focusing on its indications, techniques, and outcomes. The goal is to offer an in-depth understanding of its effectiveness in preventing previable birth and to guide clinical decision-making in managing pregnancies at risk of premature delivery. A thorough literature review examined recent studies and clinical data on RCC. Key aspects evaluated include the criteria for intervention, various surgical techniques employed, and the associated maternal and fetal outcomes. Comparative analysis was also performed with other preventive measures, such as progesterone therapy and bed rest. RCC has demonstrated efficacy in reducing the incidence of previable births, particularly when performed in cases of identified cervical incompetence or shortening. The review highlights variations in the technique, such as McDonald and Shirodkar cerclage, and discusses their relative success rates and potential complications. The procedure is associated with improved pregnancy outcomes and reduced risk of previable birth, though it carries some risks, including infection and cervical laceration. RCC remains a valuable intervention for preventing previable births in selected patients. This review underscores its importance in managing pregnancies at risk due to cervical incompetence and provides a detailed evaluation of its indications, techniques, and outcomes. Future research should optimize criteria for cerclage placement and explore novel strategies to enhance its effectiveness and safety.

Surgical Tips for Robotic Assisted Laparoscopic Abdominal Cerclage: A Minimally Invasive Approach.

Preterm birth is the leading cause of perinatal and neonatal morbidity and mortality in the developed world. An important cause of preterm birth is cervical insufficiency, leading to membrane prolapse, premature rupture of membranes, and mid-trimester pregnancy loss. A cerclage can be placed vaginally or abdominally to treat cervical insufficiency. In cases of failed prior transvaginal cerclage (TVC), transabdominal cerclage (TAC) is the alternative. The procedure can be completed via laparoscopy or open approach. The suture is placed at the internal os giving greater structural support.1 In this article, we review the definition of cervical incompetence, we present the indications for TAC, we discuss the outcomes of minimally invasive TAC compared to open approach, and we review surgical tips and tricks for robotic assisted (RA) TAC placement that can be used prior to pregnancy or in early gestation. The included images delineate the surgical technique for safe placement of robotic assisted laparoscopic abdominal cerclage in the management of cervical insufficiency.

Obstetric outcomes of transabdominal cerclage: A retrospective observational study in Japan.

This study aimed to investigate the obstetric outcomes of transabdominal cerclage (TAC) in Japan. Questionnaires on TAC were sent to 183 institutions performing high-quality perinatal management in Japan. As a first-step questionnaire, we asked whether TAC was performed between January 1, 2011, and December 31, 2022. In the second step of the questionnaire, the characteristics of all cases were asked from all institutions in which TAC was performed. The response rate for the first survey was 59% (108/183). Of the 108 institutions, 27 performed TAC (25%) in 133 pregnancies. Of these 27 institutions, 19 responded to the second survey. One hundred twenty-five pregnancies were included in this study, five of which were aborted (gestational weeks <22 weeks), and 69 babies were born after 37 gestational weeks (55%). Eighty-two open abdominal cerclages were performed at 17 institutions and 43 laparoscopic TACs at three institutions. There were no differences in the age at TAC, gestational weeks at TAC, operative time of TAC, gestational weeks at delivery, incidence rate of second-trimester loss, or preterm delivery (before 37 gestational weeks) rate between the two groups. However, blood loss during open TAC was greater than that during laparoscopic TAC. TAC is a rare surgery for cervical insufficiency in Japan. TAC may be a safe and useful method for preventing second-trimester loss and preterm delivery in high-risk patients. TAC may also be a key option in Japan to improve perinatal outcomes in patients with cervical insufficiency.

Live birth after transmyometrial embryo transfer in a patient with radical trachelectomy

ObjectiveTo report the successful utilization of transmyometrial embryo transfer (TMET) in a patient with a history of radical trachelectomy. DesignVideo article. SettingAcademic fertility center. Subject(s)A 39-year-old, para 1, woman with a history of radical trachelectomy and abdominal cerclage presented with secondary infertility. Her prior pregnancy was conceived naturally. Her first in vitro fertilization (IVF) cycle yielded only one day-7 euploid blastocyst. All attempts at performing mock embryo transfers, cervical dilatation and hysteroscopy were unsuccessful due to absence of clinically identifiable cervical tissue. The euploid embryo was transferred into a gestational carrier; however, this resulted in a biochemical pregnancy. She underwent a second IVF cycle that yielded one day-5 euploid blastocyst. Given her history, TMET was planned. The patient included in this video gave consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (such as PubMed, ScienceDirect, Scopus, etc.) and other applicable sites. InterventionTMET using the Towako® catheter. Main Outcome MeasuresImplantation, clinical pregnancy and live birth. ResultsFollowing institutional and Health Canada approval of the Towako® catheter, a transvaginal-ultrasound guided TMET was performed under sedation with intravenous midazolam and fentanyl. The day-5 euploid blastocyst from the second IVF cycle was transferred and the patient’s β-human chorionic gonadotropin (β-hCG) levels 9 and 11 days after TMET were 86 IU/L and 262 IU/L, respectively. A single intrauterine pregnancy with cardiac activity of 119 beats/min was noted at a gestational age of 7 weeks and 2 days. The patient delivered a live singleton at 35 weeks and 2 days weighing 2182 grams. ConclusionTMET is a useful clinical technique for transferring embryos in patients with acquired or congenital cervical issues in whom trans-cervical embryo transfer is either very difficult or impossible.

Relationship between amniotic fluid inflammatory factors and pregnancy outcomes after emergency cervical cerclage

Objective: To explore the relationship between amniotic fluid and peripheral blood inflammatory factors and the pregnancy outcomes after emergency cervical cerclage, and to identify effective indicators for predicting adverse pregnancy outcomes after the procedure. Methods: A case-control study was conducted, including pregnant women who were hospitalized at Sun Yat-sen Memorial Hospital, from January 1, 2013, to July 31, 2019, and underwent emergency cervical cerclage due to cervical dilatation at gestational age between 16 and 28 weeks. A total of 85 pregnant women who underwent amniocentesis for the detection of amniotic fluid inflammatory factors during the perioperative period were included. Based on whether their baby was perinatal death, the participants were divided into the case group (28 cases with perinatal death) and the control group (57 cases with live births). Univariate logistic regression analysis was performed to identify risk factors associated with adverse pregnancy outcomes, followed by multivariate logistic regression analysis to establish a regression model and nomogram. Results: (1) The levels of tumor necrosis factor α (TNF-α), interleukin (IL)-1β, IL-6, IL-8, IL-10 in the amniotic fluid during the perioperative period and postoperative serum C-reactive protein (CRP) were significantly higher in the case group compared to the control group (all P<0.05). The case group underwent emergency cervical cerclage at an earlier gestational age compared to the control group, and their cervical dilation was greater than that of the control group (all P<0.05). However, there were no significant differences in the white blood cell counts, neutrophil percentage, and the level of preoperative CRP in the peripheral blood of pregnant women during the perioperative period (all P>0.05). (2) Univariate logistic regression analysis showed that the levels of amniotic fluid WBC, TNF-α, IL-1β, IL-2 receptor (IL-2R), IL-6, IL-8, IL-10, postoperative CRP in the peripheral blood, gestational age at cerclage and cervical dilation were associated with adverse pregnancy outcomes (all P<0.05). Multivariate regression analysis indicated that only the levels of amniotic fluid WBC and TNF-α were independent risk factors for perinatal death. (3) Based on clinical practice, a multivariate logistic regression model was constructed including the levels of amniotic fluid TNF-α, WBC, gestational age at cervical cerclage, and cervical dilation. A nomogram and calibration curve were plotted, which suggested its good predictive value for adverse pregnancy outcomes. Conclusions: During the perioperative period of emergency cervical cerclage, the levels of amniotic fluid WBC, TNF-α, IL-1β, IL-2R, IL-6, IL-8, IL-10 are associated with adverse pregnancy outcomes, with amniotic fluid WBC and TNF-α showing the closest relationship. However, there is no significant correlation between maternal peripheral hemogram during the perioperative period and adverse pregnancy outcomes. A model constructed by amniotic fluid TNF-α, WBC, cervical cerclage gestational age, and cervical dilation has a good predictive effect on adverse pregnancy outcomes.

Predictive factors for perinatal bacterial transmission from colonized mothers to delivered very-low-birth-weight infants: a retrospective cohort study

This study investigated the predictive factors for perinatal bacterial transmission in very-low-birth-weight infants (VLBWIs) born to mothers with a history of intrapartum colonization. We retrospectively reviewed the medical records of 173 VLBWIs, wherein pathogens were confirmed in maternal cultures obtained from the blood, urine, and vagina during the intrapartum period from 2013 to 2020. Newborns were categorized based on microbiological tests, including gastric aspirates, endotracheal aspirates, blood, and skin/nasal swab cultures collected immediately after birth. Infants whose cultures matched their maternal pathogens were categorized into the “transmission group” (n = 45), while those who tested negative were assigned to the “control group” (n = 128). The predominant maternal-colonizing pathogen observed was Escherichia coli (30.6%), which also emerged as the primary colonizing pathogen in neonates (35.6%). Transmission group had higher incidences of maternal leukocytosis, chorioamnionitis, and cervical cerclage. Regarding neonatal characteristics, the transmission group demonstrated lower initial base excesses (− 6.3 ± 3.9 vs. − 9.2 ± 4.9, P < 0.05) and higher C-reactive protein levels (0.1 ± 0.3 vs. 0.4 ± 0.8, P < 0.05). Notably, regarding major neonatal outcomes, transmission group had higher mortality rates and incidences of severe intraventricular hemorrhage. These findings may be useful for making decisions when considering antibiotic treatment for infants with a history of maternal colonization.

Comparing cervical cerclage, pessary and vaginal progesterone for prevention of preterm birth in women with a short cervix (SuPPoRT): A multicentre randomised controlled trial.

Cervical cerclage, cervical pessary, and vaginal progesterone have each been shown to reduce preterm birth (PTB) in high-risk women, but to our knowledge, there has been no randomised comparison of the 3 interventions. The SuPPoRT "Stitch, Pessary, or Progesterone Randomised Trial" was designed to compare the rate of PTB <37 weeks between each intervention in women who develop a short cervix in pregnancy. SuPPoRT was a multicentre, open label 3-arm randomised controlled trial designed to demonstrate equivalence (equivalence margin 20%) conducted from 1 July 2015 to 1 July 2021 in 19 obstetric units in the United Kingdom. Asymptomatic women with singleton pregnancies with transvaginal ultrasound cervical lengths measuring <25 mm between 14+0 and 23+6 weeks' gestation were eligible for randomisation (1:1:1) to receive either vaginal cervical cerclage (n = 128), cervical pessary (n = 126), or vaginal progesterone (n = 132). Minimisation variables were gestation at recruitment, body mass index (BMI), and risk factor for PTB. The primary outcome was PTB <37 weeks' gestation. Secondary outcomes included PTB <34 weeks', <30 weeks', and adverse perinatal outcome. Analysis was by intention to treat. A total of 386 pregnant women between 14+0 and 23+6 weeks' gestation with a cervical length <25 mm were randomised to one of the 3 interventions. Of these women, 67% were of white ethnicity, 18% black ethnicity, and 7.5% Asian ethnicity. Mean BMI was 25.6. Over 85% of women had prior risk factors for PTB; 39.1% had experienced a spontaneous PTB or midtrimester loss (>14 weeks gestation); and 45.8% had prior cervical surgery. Data from 381 women were available for outcome analysis. Using binary regression, randomised therapies (cerclage versus pessary versus vaginal progesterone) were found to have similar effects on the primary outcome PTB <37 weeks (39/127 versus 38/122 versus 32/132, p = 0.4, cerclage versus pessary risk difference (RD) -0.7% [-12.1 to 10.7], cerclage versus progesterone RD 6.2% [-5.0 to 17.0], and progesterone versus pessary RD -6.9% [-17.9 to 4.1]). Similarly, no difference was seen for PTB <34 and 30 weeks, nor adverse perinatal outcome. There were some differences in the mild side effect profile between interventions (vaginal discharge and bleeding) and women randomised to progesterone reported more severe abdominal pain. A small proportion of women did not receive the intervention as per protocol; however, per-protocol and as-treated analyses showed similar results. The main study limitation was that the trial was underpowered for neonatal outcomes and was stopped early due to the COVID-19 pandemic. In this study, we found that for women who develop a short cervix, cerclage, pessary, and vaginal progesterone were equally efficacious at preventing PTB, as judged with a 20% equivalence margin. Commencing with any of the therapies would be reasonable clinical management. These results can be used as a counselling tool for clinicians when managing women with a short cervix.

The potential presence of infection may be indicated through non-invasive prediction of procalcitonin and C-reactive protein levels within the initial three days after cervical cerclage: a retrospective case-control study

PurposeTo identify which non-invasive infection indicators could better predict post-cervical cerclage (CC) infections, and on which days after CC infection indicators should be closely monitored.MethodsThe retrospective, single-center study included 619 single-pregnancy patients from January 2021 to December 2022. Patients were categorized into infected and uninfected groups based on physicians’ judgments of post-CC infections. Registered information included patient characteristics, cervical insufficiency history, gestational age at CC, surgical method (McDonald/Shirodkar), purpose of CC, mid-pregnancy miscarriage/preterm birth, infection history or risk factors, and infection indices on days 1, 3, 5, and 7 after CC. Propensity score matching (PSM) was applied to reduce patient characteristic bias. Statistical analysis of C-reactive protein (CRP), white blood cell (WBC), neutrophil count (NEU), percentage of neutrophil count (NEU_P), interleukin-6 (IL-6), and procalcitonin (PCT) in the infected group compared with the uninfected group was performed using chi-square tests and t-tests. Receiver operating characteristic (ROC) curves were used to further assess the diagnostic value of CRP, PCT, and CRP-PCT in combination.ResultsAmong the 619 included patients, 206 patients were matched using PSM and subsequently assessed. PCT values on day 1 and day 3 after CC exhibited significant differences between the two groups in two statistical ways (P < 0.01, P < 0.05). The CRP levels on day 1 were significantly higher in the infected group compared to the uninfected group in two statistical ways (P < 0.05). On day 3, the mean CRP value was significantly elevated in the infected group compared to the uninfected group (P < 0.05). Analyses of IL-6, WBC, NEU, and NEU_P did not yield clinically significant results. The area under the ROC curves for CRP, PCT, and CRP-PCT on day 1 and day 3 were all below 0.7. In the preventive CC group, the AUC values of CRP and CRP-PCT obtained on d1 were found to be higher than 0.7, indicating moderate diagnostic accuracy.ConclusionFor women after CC surgery, especially of preventive aim, increased serum CRP and PCT levels from post-CC day 1 to day 3 may signal a potential postoperative infection, warranting close monitoring.
