RESUMEN
Preterm birth is the most common maternal complication in twin pregnancies. In recent years, cervical cerclage has been of long-standing interest in the prevention of preterm birth in twin pregnancies. However, its clinical application in the treatment of cervical insufficiency of twin pregnancies remains a controversial subject. In addition, infection or inflammation conditions are considered to be closely related to the perinatal outcomes of twin pregnancies after cervical cerclage. This paper reviews the research progress on cervical cerclage in twin pregnancies, recommending cervical cerclage for twin pregnancies with cervical length≤15 mm or cervical dilatation, while it is not suggested for those with cervical length of 15-25 mm or history-indicated cervical cerclage. The clinical significance of preoperative evaluation of intraamniotic infection or inflammation of twin pregnancies needs to be further explored, but it is necessary to avoid the effect of antibiotic use on the evaluation of surgical effects.
RESUMEN
SUMMARY OBJECTIVE: This study aims to investigate the predictive value of hemogram parameters in early preterm delivery (32 gestational weeks and below) among pregnant women who have undergone cervical cerclage, based on cervical changes determined before the cerclage procedure. METHODS: Between 2010 and 2020, a total of 161 patients underwent cervical cerclage. The participants were divided into three groups. Group 1 (n=92) consisted of pregnant women who underwent prophylactic cerclage. Group 2 (n=31) included those with cervical shortening (<5 mm) and/or dilation (≤3 cm). Group 3 (n=38) comprised pregnant women with cervical dilation >3 cm. Each group was further divided based on delivery weeks, with a cutoff at 32 weeks. Demographic parameters and laboratory parameters were assessed. RESULTS: In Group 1, all hemogram parameters showed no significant differences between deliveries below and above 32 weeks. In Group 2, the neutrophil-to-lymphocyte ratio value before cerclage was higher in the early preterm delivery group (p=0.002), with a cutoff value of 4.75 in receiver operating characteristic analysis. In Group 3, the white blood cell value before cerclage was higher in the early preterm delivery group (p=0.005), with a cutoff value of 13.05×103/μL in receiver operating characteristic analysis. CONCLUSION: The use of hemogram parameters to predict early preterm delivery in pregnant women undergoing prophylactic cerclage is not appropriate. However, neutrophil-to-lymphocyte ratio value can predict early preterm delivery when cervical dilation is 3 cm or less and/or cervical shortening is 5 mm or less. When cervical dilation exceeds 3 cm, the white blood cell value is more appropriate for predicting early preterm delivery.
RESUMEN
Abstract Objective The aim of the present study is to compare the effectiveness of Arabin pessary and McDonald cervical cerclage on preterm delivery. Methods We conducted a retrospective analysis of data from patients who underwent either Arabin pessary or McDonald cerclage between January 1, 2019, and January 1, 2023. A total of 174 patients were included in the study, with 31 undergoing Arabin pessary and 143 receiving cervical cerclage using the McDonald technique in singleton pregnant women with cervical insufficiency, which applied between 14 and 22 gestational weeks. We included singleton pregnant women with normal morphology, and with normal combined test. The primary outcome was the impact of each method on preterm delivery (< 34 gestational weeks). Results The weeks of cervical cerclage or pessary application were compatible with each other (p< 0.680). The pessary group had a statistically significant longer time to delivery compared with the Cerclage group (cerclage group mean 30.8 c 7.1 standard deviation [SD] versus pessary group mean 35.1 ± 4.4 SD; p< 0.002). A statistically significant difference was found between the pessary and cerclage groups in terms of delivery at < 34 weeks (p= 0.002). In patients with cervical length between 25 and 15mm and < 15mm, no significant difference was found between the pessary and cerclage groups in terms of delivery week (p< 0.212; p< 0.149). Regardless of the technique applied, no statistically significant difference was observed between cervical length and birth < 34 weeks. Conclusion Our study found that pessary use for cervical insufficiency is statistically more effective than cervical cerclage surgery in preventing preterm births < 34 weeks in singleton pregnancy.

Introducción : el tratamiento de la insuficiencia cervical es el cerclaje cervical. Pese a este tratamiento el riesgo de parto prematuro persiste elevado en mujeres con insuficiencia cervical. La mejor forma y utilidad del seguimiento ecográfico de mujeres cercladas es desconocida. El objetivo de esta revisión fue evaluar la capacidad pronóstica de la ecografía transvaginal para predecir riesgo de parto prematuro luego de un cerclaje cervical. Materiales y métodos : realizamos una revisión sistemática de la literatura incluyendo estudios que evaluaran el valor pronóstico de la ecografía transvaginal luego de un cerclaje cervical, para predecir parto prematuro. Resultados : incluimos 14 estudios en la revisión. El parámetro más frecuentemente asociado con parto prematuro fue la longitud cervical posterior al cerclaje, aunque con capacidad predictiva moderada. El punto de corte para definir pacientes en riesgo varió entre 15-28 mm. Conclusión : la longitud cervical disminuida posterior a un cerclaje se asocia con mayor riesgo de parto prematuro. No se ha establecido un valor de corte único ni la utilidad clínica del seguimiento ecográfico de mujeres cercladas.
Introduction : The management of cervical insufficiency involves a cervical cerclage. Despite this treatment, patients with cervical insufficiency remain at high risk of preterm delivery. The best method and utility of ultrasound monitoring for women with cervical cerclage is unknown. The objective of this revision was to evaluate the prognostic performance of ultrasonographic cervical assessment to predict preterm labor after a cervical cerclage. Material and methods : We conducted a systematic literature review, including studies that assessed the prognostic value of transvaginal ultrasound after cervical cerclage in predicting premature birth. Results : We included 14 studies in our review. The most frequently evaluated parameter was cervical length after the cerclage, although with only moderate predictive capacity. The length used to define prognosis varied from 15 to 28 mm. Conclusion : Short cervical length after a cerclage is associated with a higher risk of preterm delivery. A single cutoff value and the clinical utility of ultrasound monitoring for women with cervical cerclage have not been established.
RESUMEN
Objective:To compare the maternal and fetal outcomes of women with cervical insufficiency (CI) undergoing McDonald cerclage (MC) and laparoscopic cervicoisthmic cerclage (LCC), so as to provide evidence for the selection of cerclage methods.Methods:A retrospective trial was carried out in the First Affiliated Hospital of Sun Yat-sen University from January 2010 to December 2020. A total of 221 women who underwent the prophylactic cerclage were divided into MC group ( n=54), LCC with MC history group ( n=28) and LCC without MC history group ( n=129) by the mode of operation and whether the pregnant women who underwent LCC had MC history. General clinical data, pregnancy complications and pregnancy outcomes were compared between the three groups. Results:(1) General clinical data: the proportion of women accepted cervical cerclage during pregnancy in MC group, LCC with MC history group and LCC without MC history group were 100.0% (54/54), 7.1% (2/28) and 27.1% (35/129), respectively ( P<0.001). The indications of the three groups showed statistical significance ( P=0.003), and the main indication was the history of abortion in the second and third trimester [75.9% (41/54) vs 89.3% (25/28) vs 84.5% (109/129)]. (2) Pregnancy complications: the incidence of abnormal fetal position [7.8% (4/51) vs 17.4% (4/23) vs 19.8% (24/121)], placenta accrete [5.9% (3/51) vs 13.0% (3/23) vs 11.6% (14/121)], uterine rupture [0 vs 4.3% (1/23) vs 5.8% (7/121)] in the MC group were all lower than those in LCC with MC history and LCC without MC history groups. However, there were no statistical significances (all P>0.05). Intrauterine inflammation or chorioamnionitis [15.7% (8/51) vs 0 vs 0.8% (1/121)] and premature rupture of membrane [23.5% (12/51) vs 4.3% (1/23) vs 0] were both significantly higher in MC group than those in LCC with MC history and LCC without MC history groups (all P<0.001). (3) Pregnancy outcomes: the cesarean section rate was significantly lower in MC group (41.2%, 21/51) than that in LCC with MC history group (100.0%, 23/23) and LCC without MC history group (100.0%, 121/121; P<0.001). MC group was associated with lower expenditure than LCC with MC history and LCC without MC history groups (12 169 vs 26 438 vs 27 783 yuan, P<0.001). The success rates of live birth cerclage did not differ significantly in MC (94.4%, 51/54), LCC with MC history (82.1%, 23/28) and LCC without MC history (93.8%, 121/129) groups ( χ2=5.649, P=0.059). There was no significant difference in neonatal intensive care unit occupancy, neonatal birth weight and neonatal asphyxia between the three groups (all P>0.05). Conclusions:Both LCC and MC are the treatment choice for women with CI, which may get similar liver birth. However, MC has the advantages of low cesarean section rate, economical and easy operation. Therefore, MC is recommended as the first choice for CI patients, and LCC is for women with failed MC.
RESUMEN
Objective:To investigate the clinical efficacy and safety of phacoemulsification and intraocular lens (IOL) implantation combined with a modified iris cerclage for cataract with mydriasis.Methods:A clinical retrospective study was conducted. Six eyes of 6 patients with cataract and mydriasis were treated with phacoemulsification and IOL implantation combined with modified iris cerclage in Department of Ophthalmology, the Affiliated Changzhou No.2 People’s Hospital of Nanjing Medical University, from January 2018 to September 2022. The best corrected visual acuity (BCVA), intraocular pressure (IOP), corneal endothelial cell count (CECC), pupil diameter and photophobia scores were statistically analysed by paired sample t test at 3 days before surgery and 3 months after surgery. The pupil shape, IOL position, intraoperative and postoperative complications were observed. P<0.05 was considered statistically significant. Results:Postoperative follow-up with all patients lasted 3 to 6 months. The BCVA at the final follow-up (0.73±0.16) was significantly improved in all 6 patients compared with that of before surgery (0.43±0.12), with statistically significant difference ( P<0.05). There was no significant difference in IOP and CECC before and after surgery ( P>0.05). The pupil diameter after surgery was significantly smaller than that before surgery ( P<0.05). The postoperative photophobia score was significantly lower than that before surgery ( P<0.05). Pupils in all 6 eyes were round-like, in a central position and without an iris capture of IOL. There was no serious intraoperative or postoperative complication. Conclusion:Phacoemulsification and IOL implantation combined with modified iris cerclage is a safe and efficient procedure that can effectively improve the visual acuity, reduce the pupil diameter, improve photophobia symptom and enhance the visual quality in patients with cataract combined with mydriasis.
RESUMEN
Objective·To investigate the distribution characteristics of vaginal flora in patients with cervical incompetence(CIC),and the effect of cervical cerclage on pregnancy outcome in patients with CIC with abnormal vaginal flora.Methods·A total of 1 261 pregnant women participated in the study.According to the diagnosis,they were divided into cervical incompetence group(CIC group)and normal pregnancy group(NP group).The CIC group patients randomly received cervical cerclage(CIC-C group)or expectation therapy(CIC-E group).Vaginal secretion samples of the patients in the groups were collected and analyzed in the laboratory.Meanwhile,through the results of vaginal flora,the CIC-C group and CIC-E group were further divided into normal vaginal flora groups(CIC-C-N group and CIC-E-N group)and abnormal vaginal flora groups(CIC-C-A group and CIC-E-A group).All groups were processed accordingly and analyzed on pregnancy outcomes.T-test and Chi-squared test were used for comparison between the groups,and One-way ANOVA was used for comparison among the three groups.Statistical significance was accepted at a value of P＜0.05.Results·Among 1 261 vaginal secretion specimens,the positive rate of pathogenic bacteria was 22.0％(277/1 261).The pathogen detection rates in the CIC group and NP group were 32.9％(229/696)and 8.5％(48/565).Twenty-three types of vaginal flora were detected in the CIC group,and 9 were detected in the NP group.The proportions of women who had term birth were 75.94％in the CIC-C group,70.03％in the CIC-E group,and 87.79％in the NP group(P=0.000).Compared with the CIC-C-A group,the CIC-E-A group had a lower term delivery rate(61.84％vs 77.78％,P=0.011)and a higher incidence of pregnancy complications(22.37％vs 9.15％,P=0.006).Conclusion·There are differences in the distribution and diversity of vaginal flora between CIC patients and normal pregnant women.Cervical cerclage can improve pregnancy outcomes in CIC patients with abnormal vaginal flora.
RESUMEN
Cervical incompetence is a common cause of late abortion and premature birth, which can be effectively treated by cervical cerclage. Controversy remains on the timing and perioperative management of cervical cerclage based on different indications. This paper briefly reviews the current differences and debates and elaborates some opinions regarding cervical cerclage in order to provide a reference for clinical decision-making and research.
RESUMEN
Objective:To compare the effect of two vs one stitch on outcomes in women with cervical incompetence who undergo emergency transvaginal cervical cerclage.Methods:A retrospective study was conducted on 38 cases of cervical incompetence patients who underwent emergency cervical cerclage at Fujian Maternity and Child Health Hospital from January 2018 to December 2022. These subjects were divided into two groups: one stitch group (loop continuous suture and knot at cervical-vaginal junction level) and two stitches group (the first loop was closed with a single suture set, and the second loop was closed below the first loop near the cervical outlet) with 19 cases in each group. Two independent samples t or t'-test, rank-sum test, Chi-square test and Fisher's exact test were used to compare the differences in perinatal outcomes between the two groups. Kaplan-Meier survival analysis was performed to evaluate the efficacy of the prolongation of gestational age after emergency transvaginal cervical cerclage. Results:There was no statistically significant difference in the gestational age at cervical cerclage between the two stitches and the one stitch group [24.9 weeks (23.9-25.9 weeks) vs 23.6 weeks (22.6-24.9 weeks), Z=－1.61, P=0.108]. The average gestational age at delivery [(33.1±4.8) vs (28.6±4.3) weeks, t=－3.10] and the prolongation of gestational age after cerclage[(8.5±4.6) vs (5.0±2.6) weeks, t=－2.90] were significantly greater in the two stitches group compared to those in the one stitch group, while the rates of preterm birth before 32 weeks (6/19 vs 16/19, χ2=10.80), 34 weeks (8/19 vs 17/19, χ2=9.47), and 37 weeks (14/19 vs 19/19, Fisher's exact test) were lower (all P<0.05). The Kaplan-Meier survival analysis demonstrated that the two stitches group had significantly higher efficacy in prolonging gestational age compared to the one stitch group [log-rank test χ2 (1)=13.10, P<0.05]. Although there was no statistically significant difference in the neonatal mortality between the two groups (2/19 vs 4/19, Fisher's exact test, P=0.660), survival neonates in the two stitches group had significantly higher birth weight [2 370.0 g (1 775.0-2 710.0 g) vs 1 300.0 g (1 210.0-1 660.0 g), Z=－3.14], lower admission rate to the neonatal intensive care unit (9/17 vs 15/15, Fisher's exact test), lower incidence of stage Ⅲ necrotizing enterocolitis (0/17 vs 5/15, Fisher's exact test), moderate-severe respiratory distress syndrome (5/17 vs 10/15, χ2=4.44), and grade Ⅲ-Ⅳ intraventricular hemorrhage (0/17 vs 7/15, Fisher's exact test) compared to those in the one stitch group (all P<0.05). Conclusion:Compared with emergency cervical cerclage with one stitch, the procedure with two stitches can prolong the gestational age and improve the neonatal prognosis more effectively.
RESUMEN
Objective:To explore the clinical efficacy of ultrasound-indicated cervical cerclage in twin pregnancies.Methods:This retrospective cohort study included 96 asymptomatic twin pregnancies with cervix length (CL)≤2.5 cm at 16-27 +6 weeks indicated by transvaginal ultrasound from January 2013 to May 2022 in Fujian Maternity and Child Health Hospital. They received either cervical cerclage (cerclage group, n=45) or conservative treatment (conservative group, n=51). The subgroup analysis was further performed after stratifying the subjects into the CL≤1.0 cm subgroup, the CL>1.0-≤1.5 cm subgroup, and the CL>1.5 cm subgroup. Two independent samples t-test, Mann-Whitney U test, and Chi-square test were used to compare the differences in the pregnancy and perinatal outcomes between different groups. Multivariate logistic regression was used to analyze the impact of cervical cerclage on pregnancy outcomes of women with different CLs. Results:The average gestational age at delivery and the prolonged gestation were significantly greater in the cerclage group than those in the conservative group [35.9 (34.9-37.0) weeks vs 34.9 (29.1-36.1) weeks; 10.7 (9.6-13.1) weeks vs 8.7 (4.8-11.0) weeks, Z=－2.59 and -3.63, both P<0.05]. The incidences of preterm birth before 34 weeks and 28 weeks, chorioamnionitis, and preterm premature rupture of membrane were lower in the cerclage group than those in the conservative group [17.8% (8/45) vs 45.1% (23/51), χ2=8.16; 2.2% (1/45) vs 15.7% (8/51), Fisher' exact test; 8.9% (4/45) vs 25.5% (13/51), χ2=4.52; 15.6% (7/45) vs 33.3% (17/51), χ2=4.03; all P<0.05]. There were no statistically significant differences in the proportion of postpartum hemorrhage and live births between the two groups (both P>0.05). In the women with CL≤1.0 cm, the cerclage group had a greater gestational age at delivery [36.0 (34.8-37.3) weeks vs 34.9 (28.6-35.4) weeks, Z=－2.61, P=0.009], greater prolonged gestation [12.3 (9.7-13.9) weeks vs 7.3 (3.4-9.1) weeks, Z=－3.34, P=0.001], higher birthweight [2 430.0 (2 173.8-2 646.3) g vs 1 900.0 (1 372.5-2 435.0) g, Z=－3.06, P=0.002], lower incidence of adverse neonatal outcomes [16.7% (6/36) vs 36.7% (11/30), χ2=4.22, P=0.048] compared with the conservative group. Multivariate Logistic regression analysis showed that cerclage reduced the risks of preterm birth before 34 and 32 weeks [ aOR (95% CI)=0.083 (0.009-0.790) and 0.092 (0.009-0.939), both P<0.05]. However, cerclage did not reduce the risk of preterm birth in women with CL>1.5 cm or CL>1.0-≤1.5 cm (both P>0.05). Conclusion:Ultrasound- indicated cervical cerclage can reduce the risk of preterm birth before 34 and 32 weeks, prolong pregnancy, and improve perinatal outcomes in asymptomatic twin pregnancies with CL≤1.0 cm.
RESUMEN
Objective:To investigate the changes in cervical length (CL) after history- indicated cerclage through serial ultrasound measurements and the predictive value of short cervix (CL≤2.5 cm) before 24 gestational weeks after cerclage in preterm delivery before 34 weeks.Methods:In this retrospective study, clinical data of 145 singleton pregnancies with history-indicated McDonald cerclage at Peking University First Hospital from January 2010 to June 2021 were collected. CL was measured through transvaginal ultrasound and recorded during the perioperative period and at ≥20-24, ≥24-28, and ≥28-32 weeks of gestation. The participants were divided into ≥34 weeks group ( n=118) and <34 weeks group ( n=27) based on the gestational age at delivery. Chi-square or independent sample t test was applied for comparison between the two groups. The relationship between CL after cerclage and preterm birth before 34 week in the two groups was analyzed using multivariate logistic regression analysis. The risk of preterm birth in women with short cervix at 20-24 weeks of gestation after cerclage was estimated. The receiver operator characteristic curve was adopted for predicting the diagnostic value of postoperative CL on pregnancy outcomes. Results:(1) Among the 145 cases, 106 cases (73.1%) had term delivery, 27 cases (18.6%) had premature delivery before 34 weeks, among which seven cases (4.8%) had late miscarriage before 28 weeks (including two cases with survived viable infants). The overall live birth rate was 96.6% (140/145). (2) In the ≥34 weeks group, CL at ≥20-24, ≥24-28, and ≥28-32 weeks of gestation were significantly longer than those in the <34 weeks group [(3.35±0.73) vs (2.39±1.03) cm, t=5.69, P=0.008; (3.14±0.75) vs (2.14±1.10) cm, t=5.65, P=0.007; (2.91±0.85) vs (1.79±1.09) cm, t=5.84, P=0.005]. (3) Multivariate logistic regression analysis showed that CL at ≥20-24, ≥24-28, and ≥28-32 weeks after cerclage were the influencing factors of preterm birth before 34 weeks [ OR (95% CI)=0.885 (0.837-0.935), 0.886 (0.837-0.937), 0.890 (0.842-0.940), respectively, all P<0.001]. (4) The area under the curve of CL at ≥20-24, ≥24-28, and ≥28-32 weeks were 0.747, 0.734, and 0.799 for predicting delivery before 34 weeks, with the sensitivity of 60.0%, 60.0%, and 80.0%, and the specificity of 87.5%, 91.3%, and 76.9%, respectively. (5) At ≥20-24 weeks after cervical cerclage, women with a short cervix accounted for 17.2% (25/145), who were 12.7 times more likely to have premature birth before 34 weeks than those with a CL over 2.5 cm ( OR=12.7, 95% CI: 4.58-35.40, P<0.001). Conclusions:Among pregnant women with history-indicated cervical cerclage, CL after cerclage at ≥20-24, ≥24-28, and ≥28-32 weeks of gestation have predictive values for pregnancy outcomes. A short cervix at ≥20-24 weeks of pregnancy after cerclage could predict premature birth before 34 weeks.
RESUMEN
Objective:To investigate the incidence and risk factors associated with preterm premature rupture of membranes (PPROM) following transvaginal cervical cerclage.Methods:This retrospective cohort study involved 170 singleton pregnancies with cervical incompetence who underwent vaginal cervical cerclage at Fujian Maternity and Child Health Hospital from January 2021 to January 2022. Based on the onset of PPROM after cervical cerclage, the patients were divided into the PPROM group ( n=28) and the non-PPROM group ( n=142). Independent samples t-test, rank-sum test, Chi-square test, or Fisher's exact test were used to compare the general condition, pre- and postoperative data, pregnancy complications or comorbidities between the two groups, with a significance level at α=0.1. Multiple logistic regression analysis was conducted to identify the risk factors for PPROM after cerclage surgery. Results:The overall incidence of PPROM after vaginal cervical cerclage was 16.5% (28/170). Logistic regression analysis showed that a history of cervical conization ( OR=11.966, 95% CI:1.695-84.468), the use of Mersilene RS22 tape as the suture material ( OR=3.318, 95% CI:1.064-9.252), cervical length<2.5 cm after cerclage ( OR=3.486, 95% CI:1.116-10.888), and Mycoplasma genitalium- positive results for cervical secretion culture after surgery ( OR=4.856, 95% CI:1.487-15.861) were the independent risk factors for PPROM after cervical cerclage (all P<0.05). Conclusions:The incidence of PPROM following vaginal cervical cerclage is relatively high and can have unfavorable effects on pregnancy outcomes. Factors such as a history of cervical conization, the use of Mersilene RS22 tape for cerclage, cervical length<2.5 cm after cerclage, and Mycoplasma genitalium-positive results for cervical secretion culture after surgery may increase the risk of PPROM after cerclage.
RESUMEN
Objective To explore the clinical efficacy of using rituximab and atoxiban in the treatment of cervical incompetence after emergency cervical cerclage surgery.Methods Sixty patients with cervical incompetence admitted from May 2020 to February 2022 were selected as the study subjects.Divide into control group A,control group B,and trial group C using random number table method,with 20 cases in each group.All three groups underwent emergency cervical cerclage surgery.After the surgical treatment,control group A received treatment with rituximab hydrochloride,control group B received treatment with atoxiban,and experimental group C received treatment with atoxiban on the basis of rituximab hydrochloride.Analyze and compare the inhibitory effects of uterine contractions,incidence of adverse reactions,and neonatal outcomes among three groups.Results The inhibition rate of uterine contractions in control group A and test group C was higher than that in control group B(P<0.05);The incidence of postoperative complications in experimental group C was lower than that in control group A and control group B,with a statistically significant difference(P<0.05);Compared with control group A and control group B,the incidence of fetal loss,neonatal asphyxia,and low birth weight infant outcomes in experimental group C was not statistically significant(P>0.05).Compared with control group A and control group B,experimental group C had a longer gestational week extension and a higher Apgar score for newborns,with statistically significant differences(P<0.05).Conclusion The combination treatment of rituximab and atoxiban after emergency cervical cerclage surgery for this disease has good effects,can better inhibit uterine contractions,appropriately prolong gestational age,improve neonatal outcomes and prognosis,and reduce adverse drug reactions in pregnant women.
RESUMEN
ABSTRACT Purpose: To determine the predictive value of maternal White Blood Cells (WBC), neutrophils, and C-Reactive Protein (CRP) for diagnosing Histological Chorioamnionitis (HCA) among women with Preterm Premature Rupture of Membranes (PPROM) who underwent cervical cerclage. Methods: A retrospective cross-sectional study was conducted among women with singleton pregnancy and PPROM, who underwent cervical cerclage during 2018-2020. Results: A total of 55 eligible women were included in the final analysis, including 36 (61.02%) cases with HCA and 19 (38.98%) without HCA. Women with HCA had higher WBC count (12.31 ± 2.80) × 109/L and neutrophil count (9.67 ± 2.90)×109/L than those without HCA (10.35 ± 2.53) × 109/L and 7.82 ± 2.82 × 109/L, respectively) (both p < 0.05). The cut-off value of WBC count at 10.15×109/L was found to be the most effective in identifying HCA, with an Area Under Curve (AUC) of 0.707 (95% CI: 0.56-0.86; p = 0.012), sensitivity of 86.11%, specificity of 57.90%, Positive Predictive Value (PPV) of 79.49%, Negative Predictive Value (NPV) of 68.75%, and Youden index of 0.44. The combination of WBC + neutrophil had a slightly higher (AUC = 0.711, 95% CI: 0.57-0.86; p = 0.011), specificity (68.42%), and PPV (81.25%), but lower sensitivity (72.22%), than the WBC count alone. A cut-off value of neutrophil at 7.46 × 109/L was effective in identifying HCA, with an AUC of 0.689 (95% CI: 0.53-0.84; p = 0.022). Discussion: Combination use of WBC+neutrophil was found to be the most accurate predictor of HCA among women with PPROM after surgery of cervical cerclage.
RESUMEN
Objective:To investigate the efficacy of modified vaginal cervical cerclage in the treatment of cervical insufficiency during pregnancy.Methods:The clinical data of 18 women with cervical insufficiency during pregnancy who received treatment in Changzhi Maternal and Child Health Hospital from January 2018 to January 2020 (including nine cases receiving modified Shirodkar operation and nine cases receiving modified McDonald operation) were retrospectively analyzed.Results:The operation process was successful in all 18 women, and there were no postoperative complications. After modified Shirodkar operation, the average gestational weeks were prolonged by 14.7 weeks. Six cases had a smooth vaginal delivery [full-term delivery in five cases and preterm premature rupture of membranes (35 weeks + 1 day) in one case]. Three women had a cesarean delivery [cesarean delivery at full-term in two cases, including twin pregnancy in one case and previous cesarean delivery in one case; preterm premature rupture of membranes because of chorioamnionitis (32 weeks + 1 day) with poor prognosis in one case]. The rate of holding babies home was 88.9%. After modified McDonald operation, the average gestational weeks were prolonged by 11.5 weeks. Five cases had a smooth vaginal delivery [full-term delivery in three cases, preterm premature rupture of membranes in one case (35 weeks + 3 days) and in one case (31 weeks)]. Three women had a cesarean delivery at full-term [secondary cesarean delivery in one case, twin pregnancy in one case, and preterm premature rupture of membrane because of preeclampsia in one case]. One case had infectious abortion, and the rate of holding the baby home was 88.9%.Conclusion:Selection of different modified operations according to the length of cervical canal can prolong gestational weeks and increase the survival rate of newborns. The modified vaginal cervical cerclage is simple and easy to operate with minimal damage to pregnant women, which is suitable for clinical promotion.
RESUMEN
Objective:To discuss the surgical effect of modified cervical cerclage for the treatment of pregnant women with cervical insufficiency.Methods:The clinical data of 225 pregnant women who underwent modified cervical cerclage in Qilu Hospital (Qingdao) were selected for retrospective analysis from April 2014 to June 2020. Surgical success rate, full-term birth rate, preterm birth rate, prolonged pregnancy weeks and newborn birth weight were compared between singleton and twin pregnancies, preventive cerclage and emergency cerclage, surgery before and after 18 weeks, naturally and in vitro fertilization and embryo transfer (IVF-ET) conceived pregnant women respectively.Results:Among the 225 pregnant women, the gestational weeks of surgery were 14-24 +5 weeks, mean gestational weeks of delivery were 38 +2 weeks (35 +5-39 +3 weeks), the number of prolonged gestation were (20.3±5.2) weeks, and the newborn birth weight was (3 065±735) g; the overall surgical success rate was 92.9% (209/225), and the miscarriage rate was 7.1% (16/225); among the surviving newborns, the full-term birth rate was 73.7% (154/209), and the preterm birth rate was 26.3% (55/209). All cases had no intraoperative complications. Among the 225 pregnant women, 202 (89.8%, 202/225) cases were singleton pregnancies, and 23 (10.2%, 23/225) cases were twin pregnancies; 201 (89.3%, 201/225) cases underwent preventive cervical cerclage, and 24 (10.7%, 24/225) cases underwent emergency cervical cerclage; 190 (84.4%, 190/225) cases underwent the surgery before 18 weeks, and 35 (15.6%, 35/225) cases underwent the surgery after 18 weeks; 49 (21.8%, 49/225) cases were conceived by IVF-ET. There was no statistically significant difference in the overall surgical success rate of single and twin group ( P>0.05). The full-term birth rate, newborn birth weight and prolonged pregnancy weeks of single group were higher than those of twin group ( P<0.05). There were no statistical differences between preventive and emergency cerclage in overall surgical success rate, full-term birth rate, preterm birth rate, and newborn birth weight (all P>0.05). The pregnancy prolonged weeks of preventive cerclage was higher than that of emergency cerclage ( P<0.05). There were no statistically significant differences in the overall surgical success rate, full-term birth rate, preterm birth rate and birth weight of newborns at different surgical timings (all P>0.05). The pregnancy prolonged week for those who underwent surgery before 18 weeks was higher than that of surgery after 18 weeks ( P<0.05). The premature birth rate of IVF-ET was higher than that of naturally conceived pregnant women ( P<0.05). Conclusion:The modified cervical cerclage could effectively prolong the gestational weeks of delivery, reduce the rate of preterm birth, and the operation is simple and easy to promote. It could be used as a surgical option for patients with cervical insufficiency.
RESUMEN
Background: Several interventions have been used to reduce the rate of preterm birth and prolonging gestation in a twin pregnancy and routine usage of cervical cerclage in twin pregnancy conceived after intra-cytoplasmic sperm injection (ICSI) procedure has found to be beneficial.Methods: Prospective case series studies, series of expectant mothers with twin pregnancy conceived by ICSI were studied under tertiary care hospital setting. A total of 108 cases with twin pregnancy were included during a period of 2016 to 2019. Obstetric profile of all the cases was taken; cervical cerclage procedure was done at 14-16 weeks of gestation (McDonald method) after a normal nuchal translucency scan and a double marker test. Pregnancy outcome parameters like abortion, preterm labour/delivery, premature rupture of membranes (PROM), and mode of delivery, gestational age at delivery, birth weight and neonatal complications were assessed.Results: Mean age of the mothers was 30.61±4.45 years, rates of the pregnancy outcome parameters were abortion 0%, preterm labour 11.1%, premature rupture of membranes (PROM) 9.3%, mean gestational age at delivery was at 34.56±1.71 weeks. Neonatal outcome parameters were mean birth weight was at 2279±470 grams, 77.8% of the neonates had normal APGAR scores. The rates of NICU admission was 28%, RDS– 24.1%, 3.7% had sepsis and 92.6% of neonates survived and 7.4% died.Conclusions: In ICSI twin pregnancies with normal cervical measurements, prophylactic cervical cerclage is effective in prolonging pregnancy and preventing preterm delivery and thereby minimizing neonatal morbidity and mortality.
RESUMEN
La insuficiencia del cérvix es una alteración del tejido cervical que impide mantener el embarazo hasta su término, provocando pérdidas fetales recurrentes en el segundo trimestre de embarazo. Se presenta un caso de incompetencia cervical, causante de tres abortos previos, el último pese a cerclaje vaginal; por tanto, se realiza cerclaje por vía abdominal, logrando un embarazo viable hasta las 35,6 semanas, que termina en cesárea por amenaza de parto pretérmino y ruptura prematura de membranas. Además, se expone una revisión de la literatura sobre el tratamiento de esta patología..Au
Incompetence of the cervix is an alteration of the cervical tissue that prevents maintaining the pregnancy until its term, causing recurrent fetal losses in the second trimester of pregnancy. A case of cervical incompetence is presented, causing three consecutive abortion, the last one despite vaginal cerclage, therefore, abdominal cerclage is performed,achieving a viable pregnancy until 35,6 weeks, ending in caesarean section due to threat of preterm delivery plus premature rupture of membranes. In addition, a review of the literature on the treatment of this pathology is presented..Au

Introducción: El parto pretérmino constituye una causa importante de morbimortalidad perinatal con repercusiones sociales y económicas a nivel mundial. La intervención oportuna ante la identificación de factores de riesgo y un adecuado manejo consiguen reducir su incidencia y evitar las consecuencias de la prematurez. Objetivo: El presente trabajo se realiza con el objetivo de destacar al pesario cervical como una herramienta mecánica en la prevención del parto pretérmino, y una opción de tratamiento en embarazos mayores de 25 semanas con insuficiencia cervical. Presentación del caso: Se trata de una paciente de 38 años de edad con antecedente de parto pretérmino espontaneo (de 33 semanas), que ingresa a las 21 semanas de embarazo con dilatación cervical de 3cm y acortamiento de la longitud cervical de 14mm, signos ecográficos: sludge y funneling. Se optó por manejo expectante con medidas complementarias: administración de antibiótico, progesterona y uso de pesario cervical. Tras el control clínico de la infección y mayor acortamiento cervical a 7mm a pesar del uso de progesterona, se colocó un pesario cervical a las 25,5 semanas, a las 27,5 semanas fue dada de alta, a las 36,6 semanas se retiró el pesario tras inicio de actividad uterina. Discusión: La progesterona y el cerclaje son medidas de elección en casos de insuficiencia cervical, sin embargo, ante las dificultades técnicas de colocación; el pesario representó una alternativa. El uso de pesario permitió que el embarazo progrese al término con resultados beneficiosos y sin evidencia de efectos adversos.
Introduction: Preterm delivery is an important cause of perinatal morbidity and mortality with global social and economic repercussions. Timely intervention in the identification of risk factors and proper management reduce their incidence and avoid the consequences of prematurity. Objective:This work is carried out with the aim of highlight the cervical pessary as a mechanical tool in the prevention of preterm birth and a treatment option in pregnancies over 25 weeks with cervical insufficiency. Case presentation: This is a 38-year-old patient with a history of spontaneous preterm delivery (33 weeks), who was admitted at 21 weeks of pregnancy with cervical dilation of 3cm and shortening of the cervical length of 14mm, ultrasound signs: sludge and funneling. Expectant management was opted, with complementary measures: administration of antibiotics, progesterone and use of a cervical pessary. After clinical control of the infection and greater cervical shortening to 7mm despite the use of progesterone, a cervical pessary was placed at 25.5 weeks, at 27.5 weeks she was discharged, at 36.6 weeks she was discharged. The pessary was removed after the start of uterine activity. Discussion: Progesterone and cerclage are the measures of choice in cases of cervical insufficiency, however, given the technical difficulties of placement; the pessary represented an alternative. Conclusion: The use of the pessary allowed the pregnancy to progress to term with beneficial results and without evidence of adverse effects.

BACKGROUND: This study aimed to evaluate the effect of cervical cerclage on the recurrence risk for preterm birth in singleton pregnant women after a twin spontaneous preterm birth (sPTB).METHODS: This multicenter retrospective cohort study included women who had a singleton pregnancy from January 2009 to December 2018 at 10 referral hospitals and a twin sPTB before the current pregnancy. We compared the cervical lengths during pregnancy and pregnancy outcomes, according to the placement of prophylactic or emergency cerclage. We evaluated the independent risk factors for sPTB (< 37 weeks of gestation) in a subsequent singleton pregnancy.RESULTS: For the index singleton pregnancy, preterm birth occurred in seven (11.1%) of 63 women. There was no significant difference in the cervical lengths during pregnancy in women with and without cerclage. In a multivariate logistic regression analysis, the placement of emergency cerclage was an independent risk factor for subsequent singleton preterm birth (odds ratio [OR], 93.188; 95% confidence interval [CI], 1.633–5,316.628; P = 0.027); however, the placement of prophylactic cerclage (OR, 19.264; 95% CI, 0.915–405.786; P = 0.057) was not a factor. None of the women who received prophylactic cerclage delivered before 35 weeks' gestation in the index singleton pregnancy.CONCLUSION: Cerclage did not lower the risk of preterm birth in a subsequent singleton pregnancy after a twin sPTB. However, emergency cerclage was an independent risk factor for preterm birth and there was no preterm birth before 35 weeks' gestation in the prophylactic cerclage group. Therefore, close monitoring of the cervical length and prophylactic cerclage might be considered in women who have experienced a twin sPTB at extreme gestation.
