RESUMO

Objective: To investigate the clinical outcomes of different treatment options on singleton short cervix and its influence factors. Methods: Totally 435 cases of singleton pregnancies who were diagnosed with short cervix (≤25 mm) between 12 to 33+6 gestational weeks in Peking University First Hospital from January 2018 to December 2018 were enrolled, including 21 cases with cervical length <10 mm, 414 cases with cervical length between 10 to 25 mm. The onset time was <24 gestational weeks in 106 cases, while 104 cases were at 24-29+6 gestational weeks and 225 cases of ≥30 gestational weeks. Gestational outcomes including delivery before 37 weeks, delivery before 34 weeks, neonatal birth weight (NBW) and adverse neonatal outcome (ANO) were compared among three treatment groups: rest group, progesterone group and cerclage group. Influence factors were also investigated. Results: (1) The incidence of short cervix in pregnancy was 7.07% (435/6 155), while 106 cases were at <24 gestational weeks (1.72%, 106/6 155), 104 cases (1.69%, 104/6 155) at 24-29+6 gestational weeks and 225 cases (3.66%, 225/6 155) at ≥30 gestational weeks. (2) In the group of cervical length <10 mm, rate of delivery before 37 and 34 weeks were 62% (13/21) and 57% (12/21) respectively. One case of progesterone treatment underwent miscarriage. Compared with rest group (n=8), delivery weeks [28.5 (25.0-40.0) vs 37.0 (28.0-40.0), P=0.020] and NBW [1 245 g (630-3 830 g) vs 2 648 g (1 560-3 830 g), P=0.028] were higher in cerclage group (n=9), while ANO was not statistically different (P>0.05). (3) In the group of cervical length ≥10 mm before 24 gestational weeks, the delivery weeks, incidence of delivery before 34 weeks, adjusted incidence of delivery before 37 weeks, NBW and ANO were not statistically different (P>0.05) among rest group (n=36), progesterone group (n=26) and cerclage group (n=34). In vitro fertilization (OR=11.97, 95%CI: 1.88-76.44, P=0.009), infection (OR=46.03, 95%CI: 5.12-413.58, P=0.001), sludge on sonography (OR=9.87, 95%CI: 1.69-57.60, P=0.011) and history of short cervix (OR=7.24, 95%CI: 1.04-50.24, P=0.045) were independent risk factors of preterm birth. (4) In the group of cervical length ≥10 mm and gestational weeks between 24-29+6, the delivery weeks, incidence of delivery before 37 weeks, incidence of delivery before 34 weeks, NBW and ANO were not statistically different (P>0.05) among rest group (n=52), progesterone group (n=34) and cerclage group (n=9). Infection was an independent risk factor of preterm birth (OR=56.40, 95%CI: 4.67-680.61, P=0.002). (5) Outcomes of 223 cases were relatively good in the group of cervical length ≥10 mm beyond 30 gestational weeks. The incidence of delivery before 34 weeks was 6.3% (14/223). The delivery weeks, incidence of delivery before 37 and 34 weeks, NBW and ANO were not statistically different (P>0.05) among 3 groups. Infection (OR=10.91, 95%CI: 2.21-53.96, P=0.003) and history of preterm birth (OR=8.63, 95%CI: 1.25-59.65, P=0.029) were independent risk factors of preterm birth. Conclusions: Short cervix is a common complication of pregnancy. Cervical cerclage is related with better outcome for patients with cervical length <10 mm. Neither progesterone nor cervical cerclage improves pregnancy outcome for >10 mm cervical length patients comparing with rest. Infection, sludge, in vitro fertilization, history of short cervix and history of preterm birth are independent risk factors of preterm birth in short cervix pregnancies.

RESUMO

To assess the association between sonography-derived cervical length measurement and preterm birth. To describe the various techniques to measure cervical length using sonography. To review the natural history of the short cervix. To review the clinical uses, predictive ability, and utility of sonography-measured short cervix. Reduction in rates of prematurity and/or better identification of those at risk, as well as possible prevention of unnecessary interventions. Intended Users Clinicians involved in the obstetrical management or cervical imaging of patients at increased risk of a short cervix. Women at increased risk of a short cervix or at risk of preterm birth. Literature published up to June 2019 was retrieved through searches of PubMed and the Cochrane Library using appropriate controlled vocabulary and key words (preterm labour, ultrasound, cervix, cervical insufficiency, transvaginal, transperineal, cervical length, fibronectin). Results were restricted to general and systematic reviews, randomized controlled trials, controlled clinical trials, and observational studies. There were no date or language restrictions. Grey (unpublished) literature was identified through searching the websites of health technology assessment agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The evidence and this guideline were reviewed by the Diagnostic Imaging Committee of the Society of Obstetricians and Gynaecologists of Canada, and the recommendations were made and graded according to the rankings of the Canadian Task Force on Preventive Health Care ( Online Appendix Table A1). Preterm birth is a leading cause of perinatal morbidity and mortality. Use of the sonographic technique reviewed in this guideline may help identify women at risk of preterm birth and, in some circumstances, lead to interventions that may reduce the rate of preterm birth.

RESUMO

Vaginal cerclage can be used to treat cervical incompetence, thus reducing the risk of an unfavourable outcome. However, in some cases, it can be ineffective. One of the challenges for the gynaecologist-obstetrician is how to deal with a subsequent pregnancy after a failure of vaginal cerclage. The recently published MAVRIC study shows that performing abdominal cerclage prior or at the beginning of pregnancy reduces the rate of late miscarriage and premature delivery compared to vaginal cerclage. This implies a birth by caesarean section, and therefore a second surgery for the woman. However, it remains to determine the best surgical technique for abdominal cerclage. In the MAVIRC study, cerclage was done by laparotomy. It shall be elucidated whether this technique is superior to laparoscopy.

RESUMO

Objective: To explore the surgical opportunity of the transvaginal cervicoisthmic cerclage in the treatment of the cervical incompetence and the effect on the pregnancy outcomes. Methods: A Retrospective controlled trial was carried out between January 2014 and December 2018 in the Department of Obstetrics and Gynecology, Sir Run Run Shaw Hospital in Zhejiang, China and a total of 1 027 patients with cervical incompetence underwent the transvaginal cerclage. According to the different surgical opportunity, the patients were divided into two groups: the conception cerclage (n=736) and the preconception cerclage (n=291), and the former were divided into two subgroups depending on the condition of the cervix, the history indicated conception cerclage (n=511) and the ultrasound indicated conception cerclage (n=225). Main outcome measures were the gestational age, term delivery rate, the fetal weight and the fetal survival rate. Results: After the cerclage, the gestational age was (36±4) weeks, the term delivery rate was 69.6% (710/1 020), the fetal weight was (3 038±624)g and the fetal survival rate was 94.7% (966/1 020). Compared with the ultrasound indicated conception cerclage subgroup, the gestational age, the term delivery rate, and the fetal weight were all significantly higher in the history indicated conception cerclage subgroup [(37±4) vs (36±5) weeks, t=2.691; 72.8% vs 62.7%,χ(2)=7.593; (3 091±594) vs (2 963±756) g, t=2.396; all P<0.05], but the fetal survival rate was comparable in these two groups(95.3% vs 92.9%, χ(2)=1.772, P>0.05). There were no significant differences in the gestational age, the term delivery rate, the fetal weight and fetal survival rate between the history indicated conception cerclage and the preconception cerclage (all P>0.05). Conclusion: The transvaginal cervicoisthmic cerclage is a promising and safe technique for improving obstetric outcomes in women with cervical incompetence, and the history indicated conception cerclage is better than the ultrasound indicated cerclage.

RESUMO

BACKGROUND: Preterm birth (PTB) remains the foremost global cause of perinatal morbidity and mortality. Thus, the prevention of spontaneous PTB still remains of critical importance. In an attempt to prevent PTB in singleton pregnancies, cervical cerclage, in combination with other treatments, has been advocated. This is because, cervical cerclage is an intervention that is commonly recommended in women with a short cervix at high risk of preterm birth but, despite this, many women still deliver prematurely, as the biological mechanism is incompletely understood. Additionally, previous Cochrane Reviews have been published on the effectiveness of cervical cerclage in singleton and multiple pregnancies, however, none has evaluated the effectiveness of using cervical cerclage in combination with other treatments. OBJECTIVES: To assess whether antibiotics administration, vaginal pessary, reinforcing or second cerclage placement, tocolytic, progesterone, or other interventions at the time of cervical cerclage placement prolong singleton gestation in women at high risk of pregnancy loss based on prior history and/or ultrasound finding of 'short cervix' and/or physical examination. History-indicated cerclage is defined as a cerclage placed usually between 12 and 15 weeks gestation based solely on poor prior obstetrical history, e.g. multiple second trimester losses due to painless dilatation. Ultrasound-indicated cerclage is defined as a cerclage placed usually between 16 and 23 weeks gestation for transvaginal ultrasound cervical length < 20 mm in a woman without cervical dilatation. Physical exam-indicated cerclage is defined as a cerclage placed usually between 16 and 23 weeks gestation because of cervical dilatation of one or more centimetres detected on physical (manual) examination. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) (26 September 2019), and reference lists of retrieved studies. SELECTION CRITERIA: We included published, unpublished or ongoing randomised controlled trial (RCTs). Studies using a cluster-RCT design were also eligible for inclusion in this review but none were identified. We excluded quasi-RCTs (e.g. those randomised by date of birth or hospital number) and studies using a cross-over design. We also excluded studies that specified addition of the combination therapy after cervical cerclage because the woman subsequently became symptomatic. We included studies comparing cervical cerclage in combination with one, two or more interventions with cervical cerclage alone in singleton pregnancies. DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles and abstracts of all retrieved articles, selected studies for inclusion, extracted data, assessed risk of bias, and evaluated the certainty of the evidence for this review's main outcomes. Data were checked for accuracy. Standard Cochrane review methods were used throughout. MAIN RESULTS: We identified two studies (involving a total of 73 women) comparing cervical cerclage alone to a different comparator. We also identified three ongoing studies (one investigating vaginal progesterone after cerclage, and two investigating cerclage plus pessary). One study (20 women), conducted in the UK, comparing cervical cerclage in combination with a tocolytic (salbutamol) with cervical cerclage alone in women with singleton pregnancy did not provide any useable data for this review. The other study (involving 53 women, with data from 50 women) took place in the USA and compared cervical cerclage in combination with a tocolytic (indomethacin) and antibiotics (cefazolin or clindamycin) versus cervical cerclage alone - this study did provide useable data for this review (and the study authors also provided additional data on request) but meta-analyses were not possible. This study was generally at a low risk of bias, apart from issues relating to blinding. We downgraded the certainty of evidence for serious risk of bias and imprecision (few participants, few events and wide 95% confidence intervals). Cervical cerclage in combination with an antibiotic and tocolytic versus cervical cerclage alone (one study, 50 women/babies) We are unclear about the effect of cervical cerclage in combination with antibiotics and a tocolytic compared with cervical cerclage alone on the risk of serious neonatal morbidity (RR 0.62, 95% CI 0.31 to 1.24; very low-certainty evidence); perinatal loss (data for miscarriage and stillbirth only - data not available for neonatal death) (RR 0.46, 95% CI 0.13 to 1.64; very low-certainty evidence) or preterm birth < 34 completed weeks of pregnancy (RR 0.78, 95% CI 0.44 to 1.40; very low-certainty evidence). There were no stillbirths (intrauterine death at 24 or more weeks). The trial authors did not report on the numbers of babies discharged home healthy (without obvious pathology) or on the risk of neonatal death. AUTHORS' CONCLUSIONS: Currently, there is insufficient evidence to evaluate the effect of combining a tocolytic (indomethacin) and antibiotics (cefazolin/clindamycin) with cervical cerclage compared with cervical cerclage alone for preventing spontaneous PTB in women with singleton pregnancies. Future studies should recruit sufficient numbers of women to provide meaningful results and should measure neonatal death and numbers of babies discharged home healthy, as well as other important outcomes listed in this review. We did not identify any studies looking at other treatments in combination with cervical cerclage. Future research needs to focus on the role of other interventions such as vaginal support pessary, reinforcing or second cervical cerclage placement, 17-alpha-hydroxyprogesterone caproate or dydrogesterone or vaginal micronised progesterone, omega-3 long chain polyunsaturated fatty acid supplementation and bed rest.

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

RESUMO

PURPOSE: To compare pregnancy outcomes in women with pPROM and a cervical cerclage in whom the cerclage was removed within 24 h and those in whom the cerclage was retained in situ. METHODS: A two-center retrospective cohort study of women with a singleton gestation with pPROM at < 340/7 weeks of gestation in the presence of cervical cerclage (January 1, 2012-July 30, 2016). Maternal and perinatal outcomes were compared between women in whom cerclage was removed within 24 h from pPROM and those in whom cerclage was retained until the onset of delivery. The primary outcome was time from pPROM to delivery. RESULTS: Seventy women met inclusion criteria. Cerclage was left in situ in 47 (67.1%) and removed in 23 (32.9%) women. Women in the cerclage retention group had a higher pPROM-to-delivery interval (7.0 ± 7.2 vs. 6.0 ± 10.9 days, p = 0.03), and were more likely to have a latency period > 48 h (87.2% vs. 65.2%, p = 0.03; aOR 3.9, 95% CI 3.1-4.9) or > 7 days (29.8% vs. 8.7%, p = 0.04; aOR 7.0, 95% CI 2.5-19.6) compared with women in whom cerclage was removed. Furthermore, chorioamnionitis rate was lower in the cerclage retention group compared to cerclage removal group (aOR 0.7, 95% CI 0.5-1.0). There were no differences between the groups in early neonatal sepsis, severe brain injury, or composite neonatal outcome. CONCLUSION: In women with pPROM and cervical cerclage, retention of cerclage may be associated with a longer latency period, and a lower chorioamnionitis rate, without an associated increase in the risk of neonatal infectious morbidity. Presentation information: The abstract of this study was presented as a poster at the 38th SMFM (Society of Maternal and Fetal Medicine) annual meeting, February 2018, Dallas, Texas, USA.

RESUMO

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.

RESUMO

OBJECTIVE: To evaluate gestational latency in individuals who did and did not receive perioperative cefazolin and indomethacin after physical examination-indicated cerclage. METHODS: This is a retrospective cohort study of all pregnant women with a singleton gestation who underwent physical examination-indicated cerclage placement and delivered at Northwestern Memorial Hospital from 2009 to 2018. Physical examination-indicated cerclage was performed in the setting of painless cervical dilation of at least 1 cm between 16 0/7 and 23 6/7 weeks of gestation. After 2014, our practice universally implemented perioperative prophylaxis of cefazolin and indomethacin. Individuals were categorized based on exposure to perioperative prophylaxis. The primary outcome was pregnancy latency at least 28 days after cerclage placement. Secondary outcomes included median latency; median gestational age at delivery; preterm birth before 28 weeks of gestation; preterm prelabor rupture of membranes; chorioamnionitis; and median birth weight. Multivariable analyses were performed, as well as a sensitivity analysis using propensity score matching. RESULTS: Cerclages were placed in 142 people: 72 (50.7%) received perioperative prophylaxis. Baseline demographics were not significantly different between groups. On multivariable analyses, individuals who received perioperative prophylaxis had a higher incidence of achieving a pregnancy latency at 28 days or more (adjusted relative risk [aRR] 1.21, 95% CI 1.05-1.40). Individuals who received perioperative prophylaxis had a significant improvement in gestational latency (+17.8 days, 95% CI 1.4-34.2 days) and birth weight (+489.8 g, 95% CI 64.6-915.0 g), with no differences in other outcomes. On sensitivity analysis, individuals receiving perioperative prophylaxis had a higher incidence of achieving a pregnancy latency at 28 days or more, (aRR 1.17, 95% CI 1.01-1.36) with no differences in other outcomes. CONCLUSION: Perioperative use of cefazolin and indomethacin prophylaxis during physical examination-indicated cerclage placement is associated with a significant prolongation in gestational latency without an increase in incidence of chorioamnionitis.

RESUMO

OBJECTIVE: To evaluate the effect of adjunctive use of vaginal progesterone after McDonald cerclage on the rate of second-trimester abortion in singleton pregnancy. METHODS: A randomized controlled trial at Woman's Health Hospital, Assiut University, Egypt, between April 2017 and March 2019 enrolled women eligible for McDonald cerclage. After cerclage, participants were randomly assigned to receive progesterone (400 mg pessary) once daily until 37 weeks or no progesterone. The primary outcome was rate of abortion before 28 weeks. Secondary outcomes included gestational age at delivery, preterm delivery, mean birthweight, Apgar score, and admission to the neonatal intensive care unit (NICU). RESULTS: The rate of spontaneous abortion was higher in the no-progesterone group (P=0.016). Mean gestational age and mean birthweight was higher in the progesterone group (P<0.001 and P=0.002, respectively). The frequency of preterm neonates, neonates with Apgar score less than 7, and admission to NICU was higher in the progesterone group than in the no-progesterone group (P=0.005, P=0.008, and P=0.044, respectively). CONCLUSION: Adjunctive use of vaginal progesterone after McDonald cerclage was found to decrease the frequency of second-trimester abortion and to improve perinatal outcomes in singleton pregnancy.

RESUMO

OBJECTIVE: To report the reproductive and obstetric outcomes of patients undergoing abdominal radical trachelectomy (ART) for the treatment of early-stage cervical cancers in Fudan, China. METHODS: We retrospectively reviewed a prospectively collected database of 360 patients with stage IA1-IB1 cervical cancers who underwent ART between 2004 and 2018. RESULTS: Overall, 211 women (58.6%) did not plan to get pregnant immediately after ART, and 89.6% of them were due to childbearing before surgery or unmarried. Among 149 women who attempted to conceive, 26 (17.4%) of them achieved 30 pregnancies. Eighty-six patients (57.7%) had infertility problems, 44 attempted to conceive with assisted reproductive technologies, and 12 (27.3%) succeeded. Post-operative cervical stenosis (26, 27.4%) and fallopian tube obstruction (22, 23.2%) were the most common reasons for infertility after surgery. Among the patients who conceived, there were 3 first-trimester miscarriages, 6 second-trimester miscarriages, and 2 elective terminations. A total of 19 pregnancies reached the third trimester, and 84.2% of them ended after 36 weeks. Twelve of 20 cases in patients with cerclage placed had full-term birth, while 3 of 5 patients without cerclage placed suffered from second-trimester miscarriage or preterm birth. CONCLUSIONS: Immediately after ART, many patients were reluctant to conceive, while others suffered from cervical stenosis or fallopian tube obstruction, which had led to low pregnancy rate. Pregnant patients might experience miscarriage or preterm labor which could be prevented by cervical cerclage. Assisted reproductive technology should be encouraged to improve obstetric outcomes.

RESUMO

Laparoscopic abdominal cerclage is emerging as the preferred treatment option for patients with refractory cervical insufficiency. Laparoscopic abdominal cerclage reduces second-trimester loss and preterm birth with success rates similar to open abdominal cerclage. Increasing evidence also suggests improved neonatal survival rates with abdominal cerclage compared with repeat vaginal cerclage in patients who delivered prematurely despite a vaginal cerclage. The option to perform a highly effective treatment using minimally invasive techniques suggests laparoscopic abdominal cerclage will become the standard of care for refractory cervical insufficiency. This review examines the literature with regard to the indications and outcomes of abdominal cerclage, highlighting the laparoscopic technique.

RESUMO

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.

RESUMO

OBJECTIVE: To assess outcomes of ultrasound and physical examination-based cerclage performed at mid to late second trimester and to assess the potential added value of progesterone treatment combined with cerclage for preventing preterm birth. STUDY DESIGN: A retrospective cohort study of women who underwent cerclage in a university-affiliated tertiary medical center (2012-2018). Inclusion criteria included only ultrasound-based cerclage and physical examination-based cerclage. Women who underwent history-based cerclage or multiple gestations were excluded. Study groups were stratified by previous PTB < 37 weeks and other risk factors for PTB. Primary outcome was the incidence of preterm birth < 35 weeks of gestation. Secondary outcomes included the potential added value of progesterone treatment and neonatal outcome. RESULTS: Sixty-nine women underwent cervical cerclage placement between 16-23 weeks of gestation. All women had short cervix (cervical length of < 25 mm) at presentation. Indications for cerclage placement included: 29% previous PTB, 32% prior cervical interventions (history of at least one D&C, hysteroscopy or cold-knife conization in the past), 22% had cervical dilatation > 1 cm at presentation, 12% due to failure of progesterone treatment defined as continued cervical shortening after 14 days of progesterone treatment, and 5% had other indications. Overall, 42 women (61%) gave birth at term. 27 women (39%) delivered prior to 37 weeks of gestation, of them, 20 women (29%) gave birth prior to 35 weeks. Overall median gestational age at delivery was 35 + 5 ± 4.7 weeks. Cervical dilatation at presentation of > 1 cm was associated with an increased risk for PTB < 35 weeks (OR 3.57, CI 1.43-30.81, p = 0.036). Previous PTB, prior cervical interventions and extent of cervical shortening at presentation did not increase the risk of PTB. Progesterone treatment in addition to cerclage did not result in a decreased risk for PTB < 35 weeks of gestation (OR 2.83, CI 0.58-13.89, p = 0.199). CONCLUSION: Late second trimester cerclage is a practical measure for preventing PTB in cases of asymptomatic cervical shortening. Our study did not find adjunctive benefit for progesterone treatment with physical or ultrasound-based cerclage in reducing the rate PTB.

RESUMO

Introducción: Las guías clínicas actuales recomiendan el uso del cerclaje de emergencia (CE) como tratamiento de la insuficiencia cervical con exposición de membranas en gestaciones únicas. Sin embargo, el CE en gestación múltiple es tema de controversia dado que no existen ensayos clínicos randomizados que demuestren su eficacia. Algunos estudios retrospectivos sugieren que el CE también podría prolongar la gestación en embarazos múltiples. El objetivo de nuestro estudio es evaluar los resultados de las gestaciones múltiples que se sometieron a un CE en nuestro centro. Materiales y métodos: Se diseñó un estudio retrospectivo que incluyó los CE realizados en gestaciones gemelares en nuestro centro entre 2007-2016. No fueron tributarias de CE gestaciones con malformaciones fetales, monocoriales-monoamnióticas, triple o superior y finalizaciones activas de la gestación. Variables primarias: latencia al parto espontáneo y edad gestacional al parto. Variables secundarias: mortalidad neonatal, ingreso en UCI neonatal, rotura prematura de membranas pretérmino, corioamnionitis y fallo del cerclaje. Resultados. El estudio incluyó 17 pacientes. La edad gestacional mediana (rango intercuartil) al parto fue de 27,1 (24,5-32,3) semanas y la latencia mediana (rango intercuartil) al parto fue de 43 (21-64) días. Hubo 4/17 (23,5%) casos de parto antes de las 24 semanas de gestación y 2/26 (7,7%) de muerte neonatal. Discusión: Estos resultados muestran que la latencia al parto después del CE en gestación múltiple es remarcable, por lo que podría ser considerado como una opción terapéutica. Sin embargo, se requiere evidencia basada en estudios randomizados para hacer una recomendación firme


Introduction: Current guidelines support the use of physical-examination indicated cerclage (PEIC) as a treatment for cervical insufficiency and membrane exposure in single pregnancies. However, PEIC in twin pregnancies is a controversial issue as no data from random clinical trial are available to demonstrate its efficacy. Few studies suggest that PEIC may prolong pregnancy also in twin pregnancies. The aim of this study was to evaluate the results of twin pregnancies that underwent a PEIC in our health centre. Material and methods: A retrospective review was performed on women that underwent a PEIC from 2007-2016 in our centre. Women were not eligible if they were carrying foetuses with major foetal anomalies, more than two foetuses or monochorionic-monoamniotic pregnancies, or three or more foetuses or requesting an elective termination of pregnancy. Primary outcomes: latency to spontaneous delivery and gestational age (GA) at delivery. Secondary outcomes: neonatal mortality and Neonatal Intensive Care Unit admission, preterm premature rupture of membranes (PPROM), chorioamnionitis and cerclage displacement. Results: The study included a total of 17 women. The median (inter-quartile range) gestational age at delivery was 27.1 (24.5-32.3) weeks, and median (inter-quartile range) latency, from cervical cerclage to delivery, was 43 (21-64) days. There were 4/17 (23.5%) cases of delivery before 24 weeks of pregnancy, and 2/26 (7.7%) cases of neonatal death. Discussion: These results suggest that latency to delivery after PEIC in twins is remarkable. Therefore, it could be considered as an optional management. Nevertheless, evidence based on random clinical trial is required to make firm recommendations on its formal use

RESUMO

OBJECTIVE: To compare pregnancy outcomes resulting from the use of cervical cerclage for different indications and investigate factors that might influence the clinical effects of cervical cerclage. MATERIALS AND METHODS: This was a retrospective study of pregnant women who received cervical cerclage in The Women's Hospital, Zhejiang University School of Medicine, China. Patients were divided into three groups: a history-indicated group; an ultrasound-indicated group and a physical examination-indicated group. The pregnancy outcomes of the three groups were then compared. Univariate and multivariate logistic regression analysis were performed to assess the independent risk factors. RESULTS: Statistical differences were evident when the history-indicated group and the ultrasound-indicated group were compared with the physical examination-indicated group for gestational age at delivery [37.3(33.3-38.9), 35.4(28.9-38.4) vs. 26.1 (24.3-28.4) weeks, respectively, P < 0.05], percentage of cases delivered at < 28 weeks of gestation (13.4%, 20.3% vs. 74.3%, respectively, P < 0.05), percentage of cases delivered at < 37 weeks of gestation (42.7%, 54.2% vs. 91.4%, respectively, P < 0.05) and fetal survival rate (88.4%, 81.4% vs. 40.0%, respectively, P < 0.05). The history-indicated group and the ultrasound-indicated group were similar with regards to these outcomes. The independent risk factors affecting the clinical effects of cervical cerclage include age, body mass index (BMI), history of prior preterm birth and second-trimester loss, C-reactive protein (CRP) >5 mg/L and cervical dilation ≥3 cm (P < 0.05). CONCLUSION: Pregnancy outcomes were similar when compared between history-indicated and ultrasound-indicated cerclage. Serial cervical surveillance is beneficial for pregnant with a history of cervical insufficiency, and the placement of cervical cerclages in response to ultrasonographically detected shortening of the cervical length is a medically acceptable alternative to the use of history-indicated cerclage.

RESUMO

OBJECTIVE: The placement of a cervical cerclage in early pregnancy could influence subsequent labor outcomes at term. Prior studies have yielded conflicting results regarding the potential association with adverse labor outcomes such as cesarean delivery (CD), cervical laceration, and prolonged labor. Our objective was to evaluate rate of CD and adverse maternal outcomes in women who labored at term with and without a cerclage within the Consortium on Safe Labor (CSL) cohort. We hypothesize that women with a cerclage in the incident pregnancy will have an increased frequency of CD and other adverse term labor outcomes. STUDY DESIGN: A retrospective cohort study was performed using data from the CSL. Women with live nonanomalous singleton gestations≥ 37 weeks with induced or spontaneous labor were identified. The risk of CD and other maternal and neonatal outcomes were compared between women with and without cerclage placement during pregnancy. Univariable and multivariable analyses were performed with adjustment for confounding factors. Planned subgroup analysis by history of CD was performed. RESULTS: A total of 374 of the 147,463 patients who met study inclusion criteria in the CSL (0.25%) had a cerclage. In univariable analysis, cerclage placement was associated with a significant increase in the frequency of CD (17.1 vs. 12.8%, p = 0.016, odds ratio: 1.4, 95% CI: 1.07-1.84), cervical lacerations, infectious morbidity, and blood loss. The association with CD persisted in multivariable regression. Cerclage placement was not associated with an increased risk of neonatal morbidity. CONCLUSION: Cerclage placement in pregnancy is associated with an increased risk of CD, cervical laceration, and infectious morbidity among women delivering at term. These findings suggest that cerclage placement may impact labor progression and outcomes. However, the magnitude of the association may not alter clinical decisions regarding cerclage placement in appropriate candidates.
