The aim of the study was to investigate if there are changes in elastographic parameters in the cervix at term around the time of delivery and if there are differences in the parameters between women with spontaneous labor and those without labor (labor induction). Nulliparous women at 36 weeks of gestation eligible for vaginal delivery were enrolled. Cervical elastography was performed and cervical length were measured using the E-CervixTM system (WS80A Ultrasound System, Samsung Medison, Seoul, Korea) at each weekly antenatal visit until admission for spontaneous labor or labor induction. E-Cervix parameters of interest included elasticity contrast index (ECI), internal os strain mean level (IOS), external os strain mean level (EOS), IOS/EOS strain mean ratio, strain mean level, and hardness ratio. Regression analysis was performed using days from elastographic measurement at each visit to admission for delivery and the presence or absence of labor against cervical length, and each E-Cervix parameter fitted to a linear model for longitudinal data measured repeatedly. A total of 96 women were included in the analysis, (spontaneous labor, n = 39; labor induction, n = 57). Baseline characteristics were not different between the two groups except for cesarean delivery rate. Cervical length decreased with advancing gestation and was different between the two groups. Most elastographic parameters including ECI, IOS, EOS, strain mean, and hardness ratio were significantly different between the two groups. In addition, ECI, IOS, and strain mean values significantly increased with advancing gestation. Our longitudinal study using ultrasound elastography indicated that E-cervix parameters tended to change linearly at term near the time of admission for delivery and that there were differences in E-Cervix parameters according to the presence or absence of labor.

Abstract Background Induction of labor is commonly performed in obstetric practice. Many methods have been suggested as good predictors of the outcome of labor induction, yet none of them is satisfactory enough. Objective To assess cervical length and uterocervical angle measured by transvaginal ultrasound as predictors of successful induction of labor. Methodology Prospective cohort study was conducted in a university-affiliated hospital over 150 nulliparous women undergoing induction of labor, in the period between May 2018 and August 2019. Transvaginal sonographic measurement of cervical length and uterocervical angle was done before induction of labor by prostaglandins. The patients were followed up till delivery and the outcome was recorded. Results The best cut-off value of cervical length for prediction of success of labor induction was 32.3 mm with 60% sensitivity and 56% specificity and the best cutoff value of uterocervical angle was 110.2 degrees with 87% sensitivity and 93% specificity. The cervical length showed a significant negative correlation while the uterocervical angle showed a significant positive correlation with the success of labor induction. Conclusion Cervical length and uterocervical angle are good predictors of successful labor induction.

Background: The current study aims to compare the efficacy of Bishop score assessment and transvaginal ultrasonographic measurement of the cervical length in prediction of the outcome of labor induction in post-term pregnancy.Methods: A comparative Prospective observational study conducted in Department of Obstetrics and Gynecology, Kom Ombo central hospital from January 2017 to October 2017. Pregnant women were classified into two groups of Bishop Score Group (1): ladies with (Bishop Score <5) = unfavorable cervix and Group (2): those with (Bishop Score >5) = favorable cervix. Also, they were classified into two groups of cervical lengths: Group (1): women with (cervical length <25mm, shorter cervix) and Group (2): those with (cervical length ≥25 mm, longer cervix). The Primary outcome was Bishop score by digital examination and Cervical length by TVS.Results: The study group was 100 women. Regarding sonographic assessment, 44 patients had cervical length <25 mm and the mean cervical length for the whole study group was 25.19±8.16 mm. Successful induction was achieved in 78 patients (78%), while CS was done in 22 patients due to failed induction.  No difference between both groups regarding the parity (p=0.063). When comparing women with successful VD versus those delivered by CS, we found significantly higher Bishop score in the first group 5.12 ± 1.93  vs 3.89 ± 1.71 in the second group (p=0.002). Additionally, VD group had significantly shorter cervix than CS group (22.31 ±7.14 vs. 35.37± 5.80 mm, p=0.007). The Bishop score showed significant moderate negative correlation with the cervical length (r=-0.589, p=0.001).Conclusions: Success of labor induction in women undergoing induction due to prolonged pregnancy can be highly predicted by cervical length as it is more objective and accurate than Bishop Score. The 25 mm cut-off point for cervical length was the best predictor of vaginal delivery.

AbstractAim:To evaluate the influence of cervical length (CL) and parity as prediction factors for assessment of cesarean section (CS) risk in women with premature rupture of membranes (PROM) at term and unfavorable cervix, undergoing induction of labor (IOL) with dinoprostone intracervical gel.Methods:A prospective study involved 50 nulliparous and 51 multiparous women admitted for IOL. Pre-induction CL was measured and delivery outcomes were recorded.Results:Nulliparous women were younger than the multiparous (26.6±5.2 vs. 30.5±4.9; P<0.001) and had longer pre-induction CL (35.6±5.5 vs. 31.5±4.8; P<0.001) and induction-delivery interval (582 vs. 420 min; P<0.001). There was no difference in the mode of delivery, CS indications, Apgar score, neonatal weight, the rate of neonatal intensive care unit admission and perinatal death in respect of parity. CL was significantly shorter in vaginal vs. cesarean deliveries regardless of parity (31.4 vs. 38.8 mm, P<0.001, respectively). Cut-off values of CL for predicting CS were 37.5 mm in nulliparae and 34.5 mm in multiparae.Conclusions:CLs of 37.5 mm in nulliparae and 34.5 mm in multiparae were determined as the cut-off values in predicting CS risk in women with PROM at term and unfavorable cervix.

Abstract Objectives To assess the risk of chorioamnionitis in nulliparous, term, singleton, vertex (NTSV) pregnancies with premature rupture of membranes (PROM) and an unfavorable cervix undergoing labor induction with either prostaglandin E2 (PGE2) or oxytocin only. Methods Retrospective cohort of NTSV pregnancies presenting with PROM who underwent labor induction with either PGE2 (n=94) or oxytocin (n=181) between October 2015 and March 2019. The primary outcome of chorioamnionitis was compared between the two groups. Statistical analysis included Chi-squared and Wilcoxon rank-sum tests, as well as logistic regression. For time to delivery, a Cox proportional hazard regression was used to determine the hazard ratio (HR) and adjusted HR (aHR). Results Baseline characteristics were similar between the two groups. Cervical ripening with PGE2 was associated with an increased rate of chorioamnionitis (18.1 vs. 6.1%; aOR 4.14, p=0.001), increased neonatal intensive care unit admissions (20.2 vs. 9.9%; aOR 2.4, p=0.02), longer time interval from PROM to delivery (24.4 vs. 17.9 h; aHR 0.56, p=<0.0001), and lower incidence of meconium (7.4 vs. 14.4%; aOR 0.26, p=0.01), compared to the oxytocin group. Conclusions Based on our data, the use of oxytocin appears both superior and safer compared to PGE2 in NTSV pregnancies with PROM undergoing labor induction.
