A Novel Transvaginal Cervical Cerclage Model for Resident Training.

ABSTRACT:

Introduction

Vaginal suturing can be challenging to teach and learn due to the surgical assistant's limited operative field visualization. Data on resident training and comfort with cerclage placement using models are limited. The aim of this activity was to assess learner satisfaction with practice using a novel model allowing for full visualization during transvaginal cervical cerclage placement.

Methods

OB/GYN residents participated in a 1-hour combined lecture and hands-on cerclage training simulation with the novel model. Pre- and postsession survey responses were assessed with descriptive statistics and paired t tests.

Results

Twenty residents with a median of 2 (SD = 1.6) years of residency experience participated. Ninety-five percent reported no prior cerclage simulation training; 60% reported placing cerclages in practice. Pre- and posttest analysis indicated a significant decrease in perceived need for further training (M = 4.05, SD = 1.07, vs. M = 3.45, SD = 0.86; p = .024) and an increase in comfort performing a cerclage placement (M = 2.55, SD = 1.16, vs. M = 3.85, SD = 0.79; p < .001). After the simulation, residents reported more comfort in cerclage placement with decreasing supervision (M = 2.05, SD = 1.02, vs. M = 2.30, SD = 1.01; p = .021); 90% reported that learning to place a cerclage was easy.

Discussion

Implementing a novel, low-cost model allowing full operative field visualization significantly improved reported comfort regarding cervical cerclage placement and resulted in high satisfaction amongst residents. Future research should evaluate the training's impact on clinical skills.

Project description:BackgroundCervical cerclage has been proposed as an effective treatment for cervical insufficiency, but there has been controversy regarding the surgical options of cervical cerclage in singleton and twin pregnancies. This study aimed to compare the pregnancy outcomes between transvaginal cervical cerclage (TVC) and laparoscopic abdominal cervical cerclage (LAC) in patients with cervical insufficiency. We also aimed to evaluate the efficacy and safety, and provide more evidence to support the application of cervical cerclage in twin pregnancies.MethodsA retrospective study was carried out from January 2015 to December 2021. The primary outcomes were the incidence of spontaneous preterm birth (sPTB) < 24 weeks, < 28, < 32, < 34 weeks, and < 37weeks, gestational age at delivery, and the incidence of admission for threatened abortion or preterm birth after cervical cerclage. The secondary outcomes included admission to the Neonatal Intensive Care Unit, adverse neonatal outcomes and neonatal death. We also analysed the pregnancy outcomes of twin pregnancies after cervical cerclage.ResultsA total of 289 patients were identified as eligible for inclusion. The LAC group (n = 56) had a very low incidence of sPTB ˂ 34 weeks, and it was associated with a significant decrease in sPTB < 28 weeks, ˂32 weeks, ˂34 and < 37 weeks, and admission to the hospital during pregnancy for threatened abortion or preterm birth after cervical cerclage (0 vs.27%; 1.8% vs. 40.3%; 7.1% vs. 46.8%; 14% vs. 63.5%, 8.9% vs. 62.2%, respectively; P < 0.001), and high in gestational age at delivery compared with the TVC group (n = 233) (38.3 weeks vs.34.4 weeks,P < 0.001). Neonatal outcomes in the LAC group were significantly better than those in the TVC group. The mean gestational age at delivery was 34.3 ± 1.8 weeks, with a total foetal survival rate of 100% without serious neonatal complications in twin pregnancies with LAC.ConclusionIn patients with cervical insufficiency, LAC appears to have better pregnancy outcomes than TVC. For some patients, LAC is a recommended option and may be selected as the first choice. Even in twin pregnancies, cervical cerclage can improve pregnancy outcomes with a longer latency period, especially in the LAC group.

Project description:ObjectiveTo compare pregnancy outcome in women at high risk of preterm birth undergoing the modified Wurm (two monofilament sutures) vs those undergoing the McDonald (single braided suture) transvaginal cervical cerclage technique.MethodsThis was a single-center prospective observational study of all women with a singleton pregnancy attending a prematurity surveillance clinic because of an increased risk of preterm birth, and undergoing history- or ultrasound-indicated transvaginal cervical cerclage. Two cerclage techniques were evaluated and the choice of cerclage was at the physician's discretion. In the modified Wurm technique using monofilament material, two circumferential sutures are placed with two insertions each (four in total). Outcomes were compared vs those of women undergoing the McDonald technique (single braided suture using a diamond-type insertion method with four insertions in total). Primary outcome was the rate of preterm birth at < 32 weeks' gestation, with planned subanalyses according to cervical cerclage indication (history- or ultrasound-indicated), preterm birth rate at any gestational age (< 37, < 34, < 28 and < 24 weeks), and sonographic cervical length (CL) of ≤ 25 mm and ≤ 15 mm. Secondary outcome measures included maternal and neonatal adverse events and outcomes, including the pre- and postsurgical characteristics. In addition, a reproducibility analysis using Bland-Altman plots was performed to evaluate the intra- and interobserver reproducibility in assessment of CL on ultrasound examination before and after cerclage.ResultsIn total, 147 patients were included in the final analysis: 55 (37%) received modified Wurm cerclage and 92 (63%) received McDonald cerclage. Other than race, demographic characteristics were comparable between the two groups. Of these, 22 (40%) women in the modified Wurm group had history-indicated cerclage, vs 50 (54%) women in the McDonald group; the remaining cerclages were ultrasound-indicated. In women with a short CL (≤ 25 mm), there was a significantly lower rate of preterm birth at < 32 weeks' gestation after modified Wurm compared with the McDonald technique (3 (9%) vs 14 (29%); adjusted odds ratio (aOR), 0.25 (95% CI, 0.06-0.95); P = 0.042). However, the study was underpowered to provide definitive conclusions. In the overall population, there was no significant difference in preterm birth rate for < 32 weeks' gestation between the two techniques (7 (13%) vs 22 (24%); aOR, 0.51 (95% CI, 0.20-1.33); P = 0.169). There was no difference in overall surgical complications between the two techniques. The pregnancy loss rate and composite neonatal morbidity/mortality rate were comparable between the two groups (2 (4%) vs 7 (8%); odds ratio (OR), 0.47 (95% CI, 0.09-2.33); P = 0.485; and 5 (9%) vs 11 (13%); OR, 0.68; (95% CI, 0.22-2.09); P = 0.593, respectively).ConclusionsIn high-risk women with a sonographic short CL, placement of a modified Wurm cervical cerclage is associated with a lower rate of preterm birth < 32 weeks compared with McDonald cervical cerclage. Further research in larger cohorts is needed to confirm this finding and to determine if this technique reduces the preterm birth rate after elective cervical cerclage without CL shortening. © 2025 The Author(s).

Project description:ObjectiveThis study aimed to assess the effectiveness of Mersilene tape versus alternative suture types in prolonging singleton pregnancies as well as other pregnancy and neonatal outcomes, in cases of history-, ultrasound-, and exam-indicated cervical cerclage.MethodsA systematic review was conducted to identify relevant studies comparing different suture types in cervical cerclage procedures. The primary outcome of interest was preterm birth (PTB) rate < 37, <35, < 28, and < 24 weeks. Statistical analyses were performed to determine the relationship between suture type and various outcomes.ResultsA total of five studies, including three randomized controlled trials (RCTs) and two retrospective studies, with a combined participation of 2325 individuals, were included. The pooled analysis indicated no significant association between suture type and PTB at less than 37 weeks of gestation (RR: 1.02, 95% CI: 0.65-1.60, p < 0.01, I2 = 74%). Women who received Mersilene tape had a higher risk of PTB at 34-37 weeks (RR: 2.62, 95% CI: 1.57-4.37, p = 0.69, I2 = 0%), but a lower risk of PTB at less than 34 weeks (RR: 0.43, 95% CI: 0.28-0.66, p = 0.66, I2 = 46%). No statistically significant differences were observed for PTB before 28 weeks (RR: 1, 95% CI: 0.65-1.53, p = 0.70, I2 = 0%), before 24 weeks (RR: 0.86, 95% CI: 0.60-1.23, p = 0.33, I2 = 0%), incidence of chorioamnionitis (RR: 0.97, 95% CI: 020-4.83, p < 0.01, I2 = 95%), neonatal intensive care unit (NICU) admission (RR: 0.79, 95% CI: 0.28-2.22, p = 0.08, I2 = 67%) and neonatal death (RR: 1.00, 95% CI: 0.42-2.35, p = 0.17, I2 = 48%).ConclusionOur findings suggest that Mersilene tape does not reduce the risk of PTB before 37, 28 or 24 weeks. We observed higher risk of preterm birth between 34 and 37 weeks with Mersilene tape but lower incidence before 34 weeks, a period with higher neonatal morbidity and mortality. Due to the limited number of studies, our results and their clinical significance should be interpreted with caution.

Project description:Transabdominal cerclage (TAC) is reported to be effective for preventing preterm birth in women with unsuccessful transvaginal cerclage (TVC) history. However, TAC has rarely been performed in twin pregnancy given the lack of sufficient evidence and the technical difficulty of the operation. Thus, it is unclear whether TAC is an effective procedure for twin pregnancy in women with a history of unsuccessful TVC. The aim of this study is to compare the characteristics and pregnancy outcomes after TAC in twin pregnancy versus singleton pregnancy, to examine whether twin pregnancy is a risk factor for very preterm birth (before 32 weeks) after TAC, and to determine whether TAC is effective in preventing preterm birth in twin pregnancy. This single-center retrospective cohort study included women who underwent TAC because of unsuccessful TVC history between January 2007 and June 2018. Of 165 women who underwent TAC, 19 had twins and 146 had singletons. Our results showed that the neonatal survival rate improved dramatically when TAC was performed (15.4% (prior pregnancy) vs 94.0% (after TAC) in twins, p<0.01; 22.8% (prior pregnancy) vs 91.1% (after TAC) in singletons, p<0.01). Moreover, the risk of very preterm birth was significantly decreased after TAC in both groups (36/39 (92.3%) (prior pregnancy) vs 2/19 (10.5%) (after TAC) in twins, p<0.01; 290/337 (86.1%) (prior pregnancy) vs 17/146 (11.6%) (after TAC) in singletons, p<0.01). More advanced maternal age and history of prior preterm delivery between 26+0 and 36+6 weeks were independently associated with very preterm birth, whereas the presence of a twin pregnancy was not associated with very preterm birth on multivariate logistic regression analysis. These results suggest that TAC is associated with successful prevention of very preterm birth and improved neonatal survival rates in the absence of procedure-related major complications in women with twin pregnancy and previous unsuccessful TVC history.

Project description:Background: The frequency of cervical insufficiency differs among the major racial and ethnic groups, with limited data specific to Asian American and Native Hawaiian/Pacific Islander (AANHPI) subpopulations. We assessed cervical insufficiency diagnoses and related outcomes across 10 racial and ethnic groups, including disaggregated AANHPI subgroups, in a large population-based cohort. Study Design: We performed a retrospective cohort study of all singleton births between 20-42 weeks' gestation in California from 2007 to 2018. Logistic regression models were performed to estimate the odds of cervical insufficiency and, among people with cervical insufficiency, the odds of cerclage and preterm birth according to self-reported race and ethnicity. Results: Among 5,114,470 births, 38,605 (0.8%) had a diagnosis code for cervical insufficiency. Compared with non-Hispanic White people, non-Hispanic Black people had the highest odds of cervical insufficiency (adjusted odds ratio [aOR] 3.07; 95% confidence interval [CI], 2.97, 3.18), for cerclage placement and higher odds for preterm birth. Disaggregating AANHPI subgroups showed that Indian people had the highest odds (aOR 1.94; 95% CI, 1.82, 2.07) of cervical insufficiency and had significantly higher odds of cerclage without increased odds of preterm birth; Southeast Asian people had the highest odds of preterm birth. Conclusion: Within a large, diverse population-based cohort, non-Hispanic Black people experienced the highest rates of cervical insufficiency, and among those with cervical insufficiency, had among the highest rates of cerclage and preterm birth. Among AANHPI subgroups specifically, Indian people had the highest rates of cervical insufficiency and cerclage placement, without increased rates of preterm birth; Southeast Asian people had the highest rates of preterm birth, without increased rates of cerclage. Disaggregating AANHPI subgroups identifies important differences in obstetric risk factors and outcomes.

Project description:IntroductionCervical insufficiency is an increased risk of midterm miscarriage and early preterm birth which increase the risk of fetal loss. This study aimed to construct a nomogram for patients with cervical insufficiency after cervical cerclage, which may assist clinicians to have individualized treatment for patients with cervical insufficiency.MethodsA study was done retrospectively from January 2013 through July 2022 in our hospital. The primary outcomes were delivered at more than 28, 30, 32, or 34 gestational weeks. Kaplan-Meier curves were applied to analyze 17 variables. All patients were randomly split (147:64) into development and validation cohorts. Based on the multivariate Cox regression analysis, a nomogram was constructed through the 'rms' package in R.ResultsA total of 211 patients with cervical insufficiency were enrolled: 121 had history-indicated cerclage; 58 had ultrasound-indicated cerclage and 32 had emergency cerclage. Times of gestations, times of miscarriages, IVF, abdominal pain, diagnostic classification, preoperative and postoperative management were demonstrated to impact overall extended days when delivering at more than 28 gestational weeks was set as the primary outcome. Except for preoperative and postoperative management, the above other five variables impacted the primary outcomes of delivering at more than 30, 32, or 34 gestational weeks. Postoperative tocolytics had an impact on the prognosis of patients who delivered at more than 30 gestational weeks. In development cohort data, a nomogram was established to predict overall extended days of patients with cervical cerclage. In present study, C-index was 0.662 in the development cohort and 0.687 in the validation cohort respectively, suggesting that the model presented some satisfied prediction. Moreover, the clinical decision curves for patients with delivering at more than 28, 30, 32 or 34 weeks set as primary outcomes also displayed that this nomogram demonstrated good clinical predictive usefulness.ConclusionsThe nomogram developed in this study may be a valuable tool assisting clinicians to evaluate outcomes of patients with cervical insufficiency after cervical cerclage, which helps them develop individualized management for the patients.

Project description:Background: The traditional surgical treatment for cervical insufficiency is vaginal placement of a cervical cerclage. However, in a small number of cases a vaginal approach is not possible. A transabdominal approach can become an option for these patients. Laparoscopic cervical cerclage is associated with good pregnancy outcomes but comes at the cost of a higher risk of serious surgical complications. The aim of the present study was to evaluate intraoperative and long-term pregnancy outcomes after laparoscopic cervical cerclage, performed either as an interval procedure or during early pregnancy, using a new device with a blunt grasper and a flexible tip. Methods: All women who underwent laparoscopic cervical cerclage for cervical insufficiency in our institution using the Goldfinger® device (Ethicon Endo Surgery, Somerville, NJ, USA) between January 2008 and March 2014 were included in the study. Data were collected from the patients' medical records and included complications during and after the above-described procedure. Results: Eighteen women were included in the study. Of these, six were pregnant at the time of laparoscopic cervical cerclage. Mean duration of surgery was 55 ± 10 minutes. No serious intraoperative or postoperative complications occurred. All patients were discharged at 2.6 ± 0.9 days after surgery. One pregnancy ended in a miscarriage at 12 weeks of gestation. All other pregnancies ended at term (> 37 weeks of gestation) with good perinatal and maternal outcomes. Summary: Performing a laparoscopic cervical cerclage using a blunt grasper device with a flexible tip does not increase intraoperative complications, particularly in early pregnancy. We believe that use of this device, which is characterized by increased maneuverability, could be an important option to avoid intraoperative complications if surgical access is limited due to the anatomical situation. However, because of the small sample size, further studies are needed to confirm our findings.
