Abstract
Background Second trimester miscarriage and preterm birth is a significant global problem. Surgical cervical cerclage is performed to prevent pregnancy loss and preterm birth. It utilises either a monofilament or braided suture. It is hypothesised that a braided material becomes colonised with pathogenic bacteria that causes vaginal dysbiosis, infection and cerclage failure. Objectives The primary objective of the study was to examine the effectiveness of using a monofilament suture material as opposed to a braided suture material on pregnancy loss in women requiring a vaginal cervical cerclage. Design Superiority open randomised controlled trial. Setting Seventy-five maternity sites across the UK. Participants Women experiencing a singleton pregnancy requiring a cervical cerclage. Interventions Monofilament suture or braided suture. Main outcome measures The primary outcome was pregnancy loss (miscarriage and perinatal mortality, including any stillbirth or neonatal death in the first week of life). Secondary outcomes included the core outcome set for preterm birth. Methods Women were randomised on a 1 : 1 basis to monofilament or braided cerclage utilising a bespoke randomisation service with minimisation dependent on the site, indication for cerclage, intention to use progesterone and planned surgical technique. The inclusion criteria were three or more previous mid-trimester losses or preterm births, insertion of a cerclage in a previous pregnancy, a history of a mid-trimester loss or preterm birth with a shortened cervical length in the current pregnancy or in women who clinicians deemed at risk of preterm birth. The exclusion criteria were an emergency or rescue cerclage, age of < 18 years, being unable to give informed consent or the cerclage having to be placed abdominally. The original sample size was calculated based on a relative risk reduction of 41% from a pregnancy loss rate of 19% in the braided group to 11% in the monofilament group with 90% power and alpha at p = 0.05. The independent data monitoring committee noted a lower-than-anticipated pooled event rate within the trial and recommended an increase in sample size to 2050. The outcome data were collected using clinical record forms from the maternal and neonatal medical records and reported to Birmingham Clinical Trials Unit. Results A total of 2049 women were randomised, after withdrawals and loss to follow-up, data on 1005 women in the monofilament group and 993 women in the braided group were included. The baseline demographics between the groups were similar. There was no evidence of a difference in pregnancy loss rates between the monofilament and braided groups (80/1003 vs. 75/993; adjusted risk ratio: 1.05, 95% confidence interval: 0.79 to 1.40; adjusted risk difference: 0.002, 95% confidence interval: -0.02 to 0.03). Limitations The trial did not collect long-term paediatric outcomes. There were no safety concerns. Conclusions There was no evidence of a difference in pregnancy loss between a monofilament suture and a braided suture. Future work Long-term follow-up of neonates born within the C-STICH (cerclage suture type for an insufficient cervix and its effects on health outcomes) trial.

Int J Gynaecol Obstet 2024. [PMID: 38822723 DOI: 10.1002/ijgo.15715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2024] [Revised: 05/13/2024] [Accepted: 05/18/2024] [Indexed: 06/03/2024]
Abstract
OBJECTIVE Previous studies have indicated that there is an association between cervical cerclage and type of suture material. However, it is still unclear which suture material can provide the greatest benefit to patients who have undergone cerclage. This study investigated the effect of two different suture materials (Mersilene tape vs braided suture) used for transvaginal cervical cerclage placement on maternal outcomes of women with cervical insufficiency. METHODS In this retrospective case-control study, 170 women who underwent history-, ultrasound-, or physical examination-indicated transvaginal cervical cerclage were categorized according to suture materials used for cerclage: a total of 96 received Mersilene tape and 74 received braided suture. Study participants received a transvaginal cervical cerclage before 28 weeks and were followed up until delivery to assess pregnancy and neonatal outcomes. The primary outcome was gestational age at delivery. Secondary outcomes included preterm premature rupture of membranes (PPROM), premature rupture of membranes (PROM), chorioamnionitis, neonatal survival rate, and neonatal morbidity. RESULTS Out of 170 eligible women, 74 (43.5%) received braided suture while 96 (56.5%) received Mersilene tape. Baseline characteristics were similar between the two groups. The group that received braided suture had a lower incidence of gestational age at delivery <37 weeks (29.2% vs 54.2%, P = 0.046), PPROM (9.5% vs 21.9%, P = 0.029) and PROM (17.6% vs 32.3%, P = 0.028) compared to the group that received Mersilene tape. However, there were no significant differences between the two groups in average gestational age at delivery, the rate of gestational age at delivery <24, <28, <32, and < 34 weeks, chorioamnionitis, and neonatal survival rate, as well as neonatal morbidity. CONCLUSION Compared to Mersilene tape, the utilization of braided suture has been significantly associated with a reduction in the incidence of gestational age at delivery <37 weeks, as well as a decreased risk of PPROM and PROM. However, the use of braided sutures did not result in discernible differences in the rates of chorioamnionitis or adverse neonatal outcomes.

Abstract
BACKGROUND Miscarriage in the second trimester and preterm birth are significant global problems. Vaginal cervical cerclage is performed to prevent pregnancy loss and preterm birth. We aimed to determine the effectiveness of a monofilament suture thread compared with braided suture thread on pregnancy loss rates in women undergoing a cervical cerclage. METHODS C-STICH was a pragmatic, randomised, controlled, superiority trial done at 75 obstetric units in the UK. Women with a singleton pregnancy who received a vaginal cervical cerclage due to a history of pregnancy loss or premature birth, or if indicated by ultrasound, were centrally randomised (1:1) using minimisation to receive a monofilament suture or braided suture thread for their cervical cerclage. Women and outcome assessors were masked to allocation as far as possible. The primary outcome was pregnancy loss, defined as miscarriage, stillbirth, or neonatal death in the first week of life, analysed in the intention-to-treat population (ie, all women who were randomly assigned). Safety was also assessed in the intention-to-treat population. The trial was registered with ISRCTN, ISRCTN15373349. FINDINGS Between Aug 21, 2015, and Jan 28, 2021, 2049 women were randomly assigned to receive a monofilament suture (n=1025) or braided suture (n=1024). The primary outcome was ascertained in 1003 women in the monofilament suture group and 993 women in the braided suture group. Pregnancy loss occurred in 80 (8·0%) of 1003 women in the monofilament suture group and 75 (7·6%) of 993 women in the braided suture group (adjusted risk ratio 1·05 [95% CI 0·79 to 1·40]; adjusted risk difference 0·002 [95% CI -0·02 to 0·03]). INTERPRETATION Monofilament suture did not reduce rate of pregnancy loss when compared with a braided suture. Clinicians should use the results of this trial to facilitate discussions around the choice of suture thread to optimise outcomes.

Abstract
RESEARCH QUESTION The study aimed to investigate the relationship between risk factors associated with vaginal microbiota and outcomes of cervical cerclage. DESIGN A retrospective cohort study of singleton pregnancies with cervical cerclage was conducted. Before cerclage, participants underwent a vaginal microbiota assay, including morphological examination and functional vaginal microecological analysis using a vaginitis multi-test kit. The chi-squared test and logistic and linear regression analyses were performed to evaluate the associations of various risk factors with maternal and neonatal outcomes. RESULTS Eighty-five participants were included. The mean interval between cerclage and delivery was 69.4 ± 36.7 days, and 12 (14.1%) of newborns died. A higher grade of vaginal cleanliness, a higher pH, a lower abundance of Lactobacillus spp., a higher sialidase-positive percentage, a higher positive percentage of clue cells, a higher lactobacillary grade, a higher Nugent score and a higher rate of microecological dysbiosis were significantly associated with a poor neonatal outcome and shorter cerclage to delivery intervals (P < 0.001-0.041). Furthermore, sialidase positivity was associated with the highest risk of cervical cerclage failure (odds ratio [OR] 10.469; 95% confidence interval [CI] 1.096-36.087), followed by the presence of bulging membranes (OR 6.400; 95% CI 0.428-15.641) and vaginal microbiota dysbiosis (OR 6.038; 95% CI 0.173-17.072). CONCLUSIONS An absence of Lactobacillus spp. and some functional factors of vaginal microbiota are potential risk factors that predict subsequent cerclage failure. These findings indicate the potential clinical utility of these factors to predict cervical cerclage failure for managing patient expectations and providing improved postoperative surveillance.

Abstract
Objective: To compare the efficacy of monofilament suture, braided polyester thread, and 5 mm tape suture in reducing preterm birth (PTB).Study design: Women who received a cerclage at Touro Infirmary, New Orleans, LA, USA, between 1 January, 2011 and 31 December, 2016 were identified using ICD-9/10 codes. All charts were reviewed for demographic and obstetrical variables including gestational age (GA) at delivery.Results: Of 145 women who received a cerclage, 36 were excluded due to incomplete charts leaving 109 for analysis. There was no significant difference in gestational age at cerclage placement or delivery among women with monofilament, braided, or 5 mm tape cerclages (p = .936 and p = .919, respectively) nor was there a difference in the proportion who delivered at ≥32, 34, or 37 weeks across groups with differing cerclage material (p = .270, p = .275, and p = .419, respectively). There was no difference in GA at delivery for patients who received 17-OHP compared to those who did not (p = .362). There were also no differences with respect to birth outcomes such as birthweight (p = .938), Apgar scores (p = .477, p = .430) or neonatal intensive care admission rates (NICU) (p = .304). Analysis revealed no difference in characteristics between groups including history of PTB or indication for removal (p = .371, p = .317).Conclusion: We found no difference in pregnancy prolongation when comparing different suture material used for indicated cerclages. We also found no differences with respect to rates of maternal infection or adverse neonatal outcomes among groups.RationaleThis study was conducted to evaluate the efficacy of different suture materials in increasing gestational age at delivery and reducing preterm birth.

Abstract
OPINION STATEMENT In patients with early-stage cervical cancer, radical hysterectomy and pelvic lymphadenectomy is the gold standard. However, this disease commonly affects women of childbearing age; thus an option to spare fertility is ideal. This option came to fruition in the early 90s when the Dargent procedure or radical trachelectomy was first reported. The procedure has subsequently been modified as technology has improved and now may be performed via minimally invasive techniques. Additionally, with the advent of the sentinel lymph node procedure, the morbidity in this usually young patient population has continued to improve. There is a multitude of data to show that oncologic outcomes, concerning recurrence and mortality, are comparable to radical hysterectomy, as well as obstetrical outcomes are favorable. Data to support its acceptance within the gynecologic oncology community has led to radical trachelectomy being implemented into governing body guidelines and should be offered to appropriate candidates with early-stage cervical cancer who wish to preserve fertility.

Abstract
Objective: To study the effect of McDonald cerclage knot position on the different maternal and neonatal outcomes. Methods: This historical cohort study included women with singleton pregnancy who had a prophylactic McDonald cervical cerclage between 1 May 2010 and 31 September 2017. Maternal and neonatal outcome parameters were compared between the anterior and posterior knot cerclage procedures. The primary outcome measure was the rate of term birth. Results: 550 Women had a prophylactic McDonald cervical cerclage, 306 with anterior knot (Group A) and 244 with posterior knot (Group B). There were no statistically significant differences regarding gestational age (GA) at delivery (36.3 ± 4.2 versus 35.8 ± 5.3 for groups A and B respectively), term birth rate, post-cerclage cervical length, symptomatic vaginitis, urinary tract infection, difficult cerclage removal and cervical lacerations. Similarly, there were no statistically significant differences as regards the studied neonatal outcomes including take home babies, neonatal intensive care admission, respiratory distress syndrome and neonatal sepsis. Survival analysis on GA at delivery demonstrated no statistically significant difference as regards the proportion of term deliveries in the anterior and posterior knot cerclage groups (log-rank test p-value = .478). Conclusions: Knot positioning during McDonald cervical cerclage, anteriorly or posteriorly, didn't significantly impact the studied maternal and neonatal outcomes.

Abstract
BACKGROUND Cervical incompetence is one of the causes of preterm birth and mid-trimester pregnancy loss. Cervical cerclage is a surgical procedure to treat cervical incompetence. Cervical cerclage reduces the incidence of preterm birth in women at risk of recurrent preterm birth, without a statistically significant reduction in perinatal mortality or neonatal morbidity. Multifilament/braided sutures such as Mersilene tape have been traditionally used for cervical cerclage. Braided sutures, particularly mesh-like non-absorbable sutures, have been associated with an increased risk of infection and, hence, some obstetricians prefer to use monofilament/non-braided sutures. However, these claims are not substantiated by any scientific or clinical evidence.We propose a pilot/feasibility study which will provide the necessary information for planning a definitive trial investigating the clinical effectiveness of monofilament non-braided suture materials in reducing pregnancy loss rate following cervical cerclage compared to the traditional multifilament braided sutures. METHODS/DESIGN Women eligible for elective or ultrasound-indicated cerclage at 12 to 21 + 6 weeks of gestation will be randomised to having the procedure using either a monofilament non-braided suture (Ethilon) or a Multifilament braided suture (Mersilene tape) inserted using a McDonald technique. Consent for participation in the Cerclage outcome by the type of suture (COTS) study will be obtained from each eligible participant. CLINICAL TRIALS REGISTRATION COTS is registered with the International Standard Research for Clinical Trials (ISRCTN17866773). Registered on 27 March 2013.

Abstract
OBJECTIVE History-indicated cervical cerclage insertion is required when factors in a woman's history could predispose to spontaneous miscarriage or preterm birth. This retrospective study determined the pregnancy outcome after insertion of history-indicated cervical cerclage for at least one previous mid-trimester spontaneous abortion over a 10-year period in a low-resource setting. METHODS This was a retrospective analysis of hospital data. Data was retrieved on biosocial and obstetrics parameters and analysed. The outcome measures were recurrence of spontaneous miscarriage, preterm delivery rate and fetal salvage rate. Descriptive frequencies were used to present results. The test of statistical significance was with Yates' coefficient correlation at 95% confidence interval. RESULTS Cervical cerclage rate was 7 per 1000 births. Diagnosis was clinical and cerclage was inserted at a mean gestational age of 15 ± 3.6 weeks. Hospital admission greater than five days after cerclage insertion had no statistically significant difference on preterm delivery (CI 95%; p value = 0.98). Repeat spontaneous miscarriage occurred less (5.6%) after cerclage insertion, fetal salvage rate was 75% and the preterm birth rate was 30%. CONCLUSION The limitations of the study notwithstanding, use of history-indicated cervical cerclage in pregnancy resulted in better fetal salvage rate and reduced recurrence of spontaneous miscarriage.
