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
PURPOSE Women diagnosed with mid-trimester cervical insufficiency and dilatation are offered interventions to salvage and support the cervix, where the mainstay of therapy is emergency cervical cerclage. However, considering the significant morbidity associated with delivery in the extreme prematurity period, some women may opt for pregnancy termination. In addition, it is expected that elective cerclage in a subsequent pregnancy may yield better obstetrical results. The objective of this study was, therefore, to compare the obstetrical outcomes of emergency cerclage versus elective cerclage. METHODS This is a retrospective cohort study of the pregnancy outcomes of women with a singleton pregnancy who underwent cervical cerclage at our institution between December 2008 and November 2021. Women who underwent emergency cervical cerclage due to painless dilatation in the second trimester were compared with women who underwent elective cerclage. RESULTS Overall, 32 women who underwent emergency cerclage and 183 women who underwent elective cerclage were included. No cases of iatrogenic membrane rupture were noted during the cerclage procedure. There was no statistical difference between the emergency cerclage group and the elective cerclage group in the primary outcomes: gestational age at delivery (35.8 + 4.7 vs 36.3 + 4.9, p = 0.58, respectively), delivery in the extreme prematurity period (between 24 and 28 gestational weeks, 6.5% vs 2.3%, p = 0.21, respectively), and fetal or neonatal death (6.9% vs 6.3%, p = 0.91, respectively). CONCLUSION Although there are much less favourable circumstances, emergency cerclage is a safe procedure with comparable obstetrical outcomes to elective cerclage. Patient selection and experienced medical team may play a significant role in those cases.

Abstract
BACKGROUND Cervical cerclage has been used for decades to reduce preterm birth. The Shirodkar and McDonald cerclage are the most commonly used techniques with no current consensus on the preferred technique. OBJECTIVE To compare the efficacy of the Shirodkar and McDonald cerclage techniques in preventing preterm birth. SEARCH STRATEGY Studies were sourced from six electronic databases and reference lists. SELECTION CRITERIA Studies including women with a singleton pregnancy, requiring a cervical cerclage, using either the Shirodkar or McDonald technique that ran comparative analyses between the two techniques. DATA COLLECTION AND ANALYSIS The primary outcome was preterm birth before 37 weeks, with analyses at 28, 32, 34 and 35 weeks. Secondary data were also collected on neonatal, maternal and obstetric outcomes. MAIN RESULTS Seventeen papers were included: 16 were retrospective cohort studies and one was a randomised controlled trial. The Shirodkar technique was significantly less likely to result in preterm birth before 37 weeks than the McDonald technique (relative risk [RR] 0.91, 95% CI 0.85-0.98). This finding was supported by a statistically significant reduction in rates of preterm birth before 35, 34 and 32 weeks, PPROM, difference in cervical length, cerclage to delivery interval, and an increase in birthweight in the Shirodkar group. No difference was seen in preterm birth rates <28 weeks, neonatal mortality, chorioamnionitis, cervical laceration or caesarean section rates. The RR for preterm birth prior to 37 weeks was no longer significant when sensitivity analyses were performed removing studies with a serious risk of bias. However, similar analyses removing studies that utilised adjunctive progesterone strengthened the primary outcome (RR 0.83, 95% CI 0.74-0.93). CONCLUSION Shirodkar cerclage reduces the rate of preterm birth prior to 35, 34 and 32 weeks' gestation when compared with McDonald cerclage; however, the overall quality of the studies in this review is low. Further, large, well-designed randomised controlled trials are required to address this important question to optimise care for women who may benefit from cervical cerclage.

Abstract
OBJECTIVE To describe a new technique for performing an isthmic retroperitoneal cerclage via vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES). DESIGN Stepwise explanation of the surgical technique using original video footage. This study was exempted from requiring hospital IRB. SETTING Department of Obstetrics and Gynaecology, Imelda Hospital, Belgium. INTERVENTION A circumferential vaginal incision is made around the cervix after infiltration of the tissue with local anaesthetic and adrenaline. The bladder is deflected from the cervix up to the level of the isthmus but the peritoneum is not opened. The rectum is deflected from the cervix up to the level of the isthmus but the peritoneum is not opened. A Gelpoint vPath (9.5 cm) (Applied Medical, Rancho Santa Margarita) is used as a vNOTES port. The inner ring of the Alexis is inserted into the retroperitoneal dissection space around the cervix, covering the bladder anteriorly and the rectum posteriorly. An insufflation stabilization bag (ISB) is connected to the Gelseal cap to minimize pressure fluctuations within the confines of the retroperitoneal operative space. The paracervical space is opened just inferior to the uterine artery. A paracervical tunnel is made from the anterior to the posterior retroperitoneal space just lateral to the cervix and just inferior to the uterine artery. This procedure is performed bilaterally. A vessel loop is inserted from anterior to posterior through the paracervical tunnel on each side of the cervix. The Gelseal cap is removed and an Ethibond-2 suture is tied to the vessel loop. The Gelseal cap is placed again. By pulling on the vessel loop, it is replaced by the Ethibond suture. The Ethibond suture is now tied endoscopically to complete the cerclage; alternatively the suture could be tied vaginally without endoscopic instruments to the surgeon's preference. The vNOTES port is removed and the vaginal mucosa is sutured to the cervix again using a resorbable suture. DISCUSSION Abdominal cerclage is the preferred approach to treat patients with refractory cervical insufficiency [1]. Over the last 20 years this technique increasingly gets performed laparoscopically with similar success rates [2]. The new transvaginal approach demonstrated in this video article may help reduce the invasivess even more by avoiding abdominal incisions and opening the peritoneum, while still benefiting from the vNOTES endoscopic visualization and minimally invasive instruments [3]. The cerclage is placed permanently at the level of the isthmus, similar to an abdominal cerclage. It is placed more cranially than a McDonald or Shirodkar cerclage and leaves no non-resorbable sutures in the vagina [4]. It can be an alternative to a conventional transvaginal cervicoisthmic cerclage [5,6] in patients with a narrow vagina and without uterine descensus. Following the guidelines of the IDEAL collaboration we present this technique to be peer reviewed in its early developmental phase before starting further studies [7]. CONCLUSION This is a first feasibility and technique description report on performing a retroperitoneal isthmic cervical via vNOTES. This technique should be considered new, not to be performed on pregnant patients or outside of clinical trials, and only in carefully counselled patients.

Abstract
Cerclages can be used to prevent preterm birth, although their effectiveness and safety is disputed. We aimed to describe obstetric outcomes after cerclage procedures. We included 156 singleton pregnancies and six multiple pregnancies. In singleton pregnancies with history-indicated, short cervix-indicated and emergency cerclages, respectively 84.6, 76.5 and 43.8% resulted in late preterm or term deliveries. In singletons, the following complications were reported: excessive bleeding in one emergency cerclage procedure and three re-cerclage procedures in the history-indicated cerclage group. No perioperative rupture of membranes occurred in singletons. When comparing results of experienced and less-experienced gynaecologists, a remarkably smaller take home child rate was observed for singletons treated by less-experienced gynaecologists: 90.7% and 94.4% for the two experienced gynaecologist as compared to 85.0% for the group of less-experienced gynaecologists. In conclusion, cerclages in singletons result in few cerclage-associated complications and a high take home child rate, when performed by experienced gynaecologists. Impact statementWhat is already known on this subject? Prematurity is the leading cause of perinatal and neonatal mortality and morbidity worldwide. Cervical cerclages can be used to prevent preterm birth, although their effectiveness and safety is disputed.What the results of this study add? In our cohort study, singleton pregnancies with cerclages seem to have satisfactory obstetric outcomes. We found a very low prevalence of cerclage-associated complications in singleton pregnancies, for both history-indicated, short cervix-indicated and emergency cerclages. Additionally, take home child rates in singleton pregnancies were remarkably higher when cerclage procedures were performed by experienced gynaecologists, compared to less experienced gynaecologists.What the implications are of these findings for clinical practice and/or further research? Based on the observed difference in take home child rates, we advise all cerclage procedures to be performed by experienced gynaecologists only. This may mean that women with an indication for cerclage will be referred to a more experienced colleague, either in the same, or in another hospital. To ensure treatment by an experienced gynaecologist, simulation-based training could also provide a solution.

Abstract
BACKGROUND Preterm birth (PTB) is the leading cause of death in children under five years. Spontaneous preterm birth (SPTB) is the major cause of preterm delivery. The key risk factors for SPTB are women who have a short cervix and women who have had previous preterm birth. Cervical cerclage has been used for several decades and has shown to decrease rates of preterm birth. The most commonly used cerclage techniques were described by Shirodkar and McDonald, with no current consensus on the preferred technique. The objective of this review is to determine and compare the effectiveness of both techniques. METHODS Studies will be sourced from six electronic databases, as well as from experts in the field, reference lists, and grey literature. Eligible studies will include pregnant women, with a singleton or twin pregnancy, requiring a cervical cerclage, using either the Shirodkar or McDonald technique and run comparative analyses between the two techniques. Randomized control trials (RCT)s, non-randomized control trials, and cohort studies will be eligible. Two independent reviewers will conduct study screening at abstract and full-text level, data extraction and risk of bias assessment. Discrepancies will be resolved by a consensus third reviewer if required. Fixed-effects or random-effects models will be used where appropriate to synthesize results. Alternative synthesis methods will be investigated in instances where a meta-analysis is not appropriate, such as summarizing effect estimates, combining P values, vote counting based on direction of effect, or synthesis in narrative form. DISCUSSION This review will synthesize the evidence on both the Shirodkar and McDonald cerclage method, and will help clinicians and health services to determine and deliver best practice antenatal care that has the potential to make an impact on preterm birth. SYSTEMATIC REVIEW REGISTRATION PROSPERO on 25 of May, 2020 with registration number CRD42020177386.

Abstract
OBJECTIVE To compare pregnancy outcomes of patients undergoing either McDonald or Shirodkar cervical cerclage. METHODS PubMed, Web of Science, Scopus, and Google scholar were systematically searched up to June 2020. Inter-study heterogeneity was assessed using Cochrane's Q test and the I2 statistic. Data were pooled using the fixed- or random-effects model and expressed as relative risk (RR) or weighted mean difference (WMD) as appropriately. RESULTS A total of eight observational studies, reporting data on 724 pregnancies, were included in this meta-analysis. As compared to the Shirodkar cerclage, the pooled findings showed that the gestational age at delivery (WMD = -1.95, 95% CI: -2.89 to -1.01, p < .001; I2 = 57.5%) and birth weight (WMD = -355.69, 95% CI: -413.76 to -297.62, p < .001; I2 = 28.8%) were significantly lower in McDonald cerclage. The risk of preterm premature rupture of the membranes (PPROM) (RR = 1.76; 95% CI: 1.14 - 2.71; I2 = 0.0%) and neonatal intensive care unit (NICU) admission (RR = 1.61; 95% CI: 1.09 - 2.39; I2 = 62.1%) were also higher for McDonald group. However, no significant difference was observed between both groups in terms of cesarean delivery and perinatal/neonatal death. CONCLUSION McDonald cerclage is associated with a shorter duration of pregnancy, lower mean birth weight and increased risk of PPROM and NICU admission compared to the Shirodkar procedure.

Abstract
Purpose: We compared the efficacy of modified Shirodkar and McDonald rescue cerclage techniques in women with singleton pregnancies.Methods: The study sample included 47 women who presented at two tertiary hospitals in Turkey from 2008 to 2017 and underwent rescue cerclage due to cervical incompetence and cervical dilatation with fetal membranes prolapsed into the vagina. The outcomes were compared by cerclage technique used, Shirodkar or McDonald.Results: The McDonald cerclage was applied in 27 cases, and modified Shirodkar cerclage in 20 cases. A longer cerclage-to-birth interval (83.8 ± 37.6 vs. 63.7 ± 38.9 days) and later gestational age at delivery (33 vs. 31 weeks) were observed with the Shirodkar cerclage, although these differences were not statistically significant (p = .08 and .63, respectively). Both groups had similar delivery rates after 28, 32, and 37 weeks (p = .20, .15, and .25, respectively), whereas the modified Shirodkar technique resulted in a higher rate of live births although these differences were not statistically significant (85% vs. 63%, p = .09).Conclusion: The effects of the McDonald and modified Shirodkar cerclage procedures on prolonging pregnancy and improving the live birth rate were similar. Therefore, either technique can be applied to prevent neonatal loss due to advanced prematurity.

Abstract
OBJECTIVE To investigate the outcomes of singleton pregnant women with cervical insufficiency undergoing two different cervical cerclages. METHODS This is a retrospective cohort study of women who underwent a history- or ultrasound-indicated cerclage (either Shirodkar or McDonald) at a tertiary referral center from 2002 to 2014. Outcome parameters (delivery age, postoperative cervical length, preterm premature rupture of membranes, preterm delivery rate and neonatal complications) were compared between the two cerclage procedures. Multivariate logistic regression analysis was applied to control for significant variables of preterm birth. Kaplan-Meier survival analysis was used to demonstrate delivery age to percentage of term delivery by cerclage type. RESULTS Ninety-four cases were initially included. After excluding cases not meeting the study criteria, 60 pregnancies (Shirodkar 36 and McDonald 24) were recruited for analysis. The mean delivery age in the Shirodkar group was more advanced than that in the McDonald group (37.1 ± 3.3 versus 34.8 ± 4.9 weeks, p = 0.039). There were significantly fewer deliveries <37 gestational weeks in the Shirodkar group than in the McDonald group (30.6% versus 58.3%, p = 0.033) but no significant differences in deliveries <28, 32 and 34 gestational weeks. No significant differences were found in neonatal complications except for respiratory distress syndrome (5.6% in Shirodkar versus 29.2% in McDonald, p = 0.023). CONCLUSION In the setting of history-indicated or ultrasound-indicated cerclage, Shirodkar was superior to McDonald in the prevention of late preterm birth and neonatal respiratory distress syndrome.

Abstract
Background Several techniques of emergency vaginal cerclage have been proposed in case of unexpected and abrupt cervical incompetence (CI), in order to prolong the pregnancy as much as possible and to reduce the adverse maternal-fetal outcomes. The aim of our study was to evaluate the effectiveness of emergency cervical cerclage, performed with the combined modified Shirodkar-McDonald technique. Methods We selected 12 cases of emergency vaginal cerclage, performed between January 1, 2008 and June 30, 2013. The age of the patients was between 20 and 38 years (mean 29.0 ± standard deviation (SD) 5.69), parity between 0 and 2 (mean 0.7 ± SD 0.65), and gestational age at the time of admission ranged between 17 and 26 weeks (mean 21.0 ± SD 3.44). In all these cases, we used a combined modified Shirodkar-McDonald technique to perform the procedure. Results The neonatal survival rate was 83.3%. The cesarean section rate was 16.7%. The average pregnancy prolongation was 89.9 days, higher than that reported for other studies in the literature. Conclusions We can assume that the emergency vaginal cerclage performed with the combined modified Shirodkar-McDonald technique is the best option of surgical therapy for the treatment of unexpected and abrupt CI.
