Favorable surgical and obstetrical outcomes in pre- and postconceptional laparoscopic abdominal cerclage: a large multicenter cohort study. Am J Obstet Gynecol MFM 2024; 6:101227. [PMID: 37984689 DOI: 10.1016/j.ajogmf.2023.101227] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2023] [Revised: 11/04/2023] [Accepted: 11/15/2023] [Indexed: 11/22/2023]
Abstract
BACKGROUND Cervical incompetence is an important cause of extremely preterm delivery. Without specialized treatment, cervical incompetence has a 30% chance of recurrence in a subsequent pregnancy. Recently, the first randomized controlled trial showed significant superiority of abdominal cerclage compared with both high and low vaginal cerclage in preventing preterm delivery at <32 weeks of gestation and fetal loss in patients with a previous failed vaginal cerclage. OBJECTIVE This study aimed to assess surgical and obstetrical outcomes in patients with pre- and postconceptional laparoscopic abdominal cerclage placement. Furthermore, it also aimed to perform subgroup analysis based on the indication for cerclage placement in order to identify patients who benefit the most from an abdominal cerclage. STUDY DESIGN A retrospective multicenter cohort study with consecutive inclusion of all eligible patients from 1997 onward in the Dutch cohort (104 patients) and from 2007 onward in the Boston cohort (169 patients) was conducted. Eligible patients had at least 1 second- or third-trimester fetal loss due to cervical incompetence and/or a short or absent cervix after cervical surgery. This includes loop electrosurgical excision procedure, conization, or trachelectomy. Patients were divided into the following subgroups based on the indication for cerclage placement: (1) previous failed vaginal cerclage, (2) previous cervical surgery, and (3) other indications. The third group consisted of patients with a history of multiple second- or early third-trimester fetal losses due to cervical incompetence (without a failed vaginal cerclage) and/or multiple dilation and curettage procedures. The primary outcome measure was delivery at ≥34 weeks of gestation with neonatal survival at hospital discharge. Secondary outcome measures included surgical and obstetrical outcomes, such as pregnancy rates after preconceptional surgery, obstetrical complications, and fetal survival rates. RESULTS A total of 273 patients were included (250 in the preconceptional and 23 in the postconceptional cohort). Surgical outcomes of 273 patients were favorable, with 6 minor complications (2.2%). In the postconceptional cohort, 1 patient (0.4%) had hemorrhage of 650 mL, resulting in conversion to laparotomy. After preconceptional laparoscopic abdominal cerclage (n=250), the pregnancy rate was 74.1% (n=137) with a minimal follow-up of 12 months. Delivery at ³34 weeks of gestation occurred in 90.5% of all ongoing pregnancies. Four patients (3.3%) had a second-trimester fetal loss. The indication for cerclage in all 4 patients was a previous failed vaginal cerclage. The other subgroups showed fetal survival rates of 100% in ongoing pregnancies, with a total fetal survival rate of 96%. After postconceptional placement, 94.1% of all patients with an ongoing pregnancy delivered at ³34 weeks of gestation, with a total fetal survival rate of 100%. Thus, second-trimester fetal losses did not occur in this group. CONCLUSION Pre- and postconceptional laparoscopic abdominal cerclage is a safe procedure with favorable obstetrical outcomes in patients with increased risk of cervical incompetence. All subgroups showed high fetal survival rates. Second-trimester fetal loss only occurred in the group of patients with a cerclage placed for the indication of previous failed vaginal cerclage, but was nevertheless rare even in this group.

Eradication of cervical canal colonization associated with prophylactic cervical cerclage: the look further study. Ginekol Pol 2023; 95:92-98. [PMID: 37842993 DOI: 10.5603/gpl.96507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Accepted: 07/27/2023] [Indexed: 10/17/2023] Open
Abstract
OBJECTIVES The perioperative management of the cervical cerclage procedure is not unified. In general population controlling microbiome cervical status does not affect obstetric outcomes, but it might be beneficial in patients with cervical insufficiency. The aim of our study was to present the obstetric, neonatal and pediatric outcomes of patients undergoing the cervical cerclage placement procedure in our obstetric department using a regimen of care that includes control of the microbiological status of the cervix and elimination of the pathogens detected. MATERIAL AND METHODS Thirty-five patients undergoing cervical cerclage in the 2nd Department of Obstetrics and Gynecology, Medical University of Warsaw, were included in the study. The procedure was performed only after receiving a negative culture from the cervical canal. RESULTS Thirty-one (88.6%) patients delivered after the 34th and twenty-eight (80.0%) after the 37th week of gestation. The colonization of the genital tract was present in 31% of patients prior to the procedure, in 42% of patients - during the subsequent pregnancy course and in 48% of patients - before delivery. A total of 85% of patients who had miscarriage or delivered prematurely had abnormal cervical cultures. In patients with normal cervical cultures, and 91.7% of women delivered at term. No abnormalities in children's development were found. CONCLUSIONS Controlling microbiological status of the cervical canal results in better or similar outcomes to those reported by other authors in terms of obstetric and neonatal outcomes. Active eradication of the reproductive tract colonization potentially increases the effectiveness of the cervical cerclage placement.

Protruding vs. visible prolapsed fetal membranes adversely affects the outcome of cervical insufficiency. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2023; 27:9937-9946.

Abstract
OBJECTIVE This study aimed to determine how prolapsed fetal membranes (PFM) affect perinatal outcomes in cases of cervical insufficiency undergoing emergency cerclage or expectant management. PATIENTS AND METHODS This retrospective study analyzed perinatal outcomes in 100 pregnant women with cervical insufficiency, including those with visible PFM at the cervical external os and those with protruding PFM to the vagina. The participants were subjected to either expectant management involving prescribed bedrest or emergency cerclage. RESULTS In the study population, 41 (41%) preferred bedrest, while 59 (59%) chose emergency cerclage. Among those managed expectantly, 10 (10%) had visible PFM, and 31 (31%) had protruding PFM. Among those who underwent emergency cerclage, 32 (32%) had visible PFM, and 27 (27%) had protruding PFM. Delivery after 32 weeks of gestation showed similar rates between women with visible and protruding PFM, regardless of the management approach chosen. These rates were significantly higher compared to those with protruding PFM managed with bed rest and emergency cerclage. Prolongation of pregnancy in protruding-cerclage and protruding-bedrest groups was 42.3±34 and 17.9±22 days, respectively. CONCLUSIONS Our findings provide support for considering emergency cerclage as a viable option when addressing cases involving a visible form of PFM, although the recommendation is somewhat less robust in instances of protruding PFM. The implementation of an emergency cerclage procedure has the potential to extend the time frame between diagnosis and delivery, enhance neonatal survival rates, and increase the likelihood of births occurring after 28 weeks of gestation. However, it does not seem to significantly affect the rate of births taking place after 32 weeks of gestation. This could potentially lead to complications associated with premature births and extended stays in the postnatal neonatal intensive care unit. Therefore, it is crucial to offer families detailed information regarding the pros and cons of emergency cerclage.

The efficacy of emergency cervical cerclage in singleton and twin pregnancies: a systematic review with meta-analysis. Am J Obstet Gynecol MFM 2023; 5:100971. [PMID: 37084870 DOI: 10.1016/j.ajogmf.2023.100971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 03/31/2023] [Accepted: 04/09/2023] [Indexed: 04/23/2023]
Abstract
OBJECTIVE An emergency (rescue) cervical cerclage can be offered to pregnant women presenting with dilatation and prolapsed membranes in the second trimester of pregnancy because of cervical insufficiency. This study aimed to investigate the effectiveness of an emergency cerclage in both singleton and twin pregnancies in the prevention of extreme premature birth. DATA SOURCES We performed a systematic literature search in PubMed and Embase from inception to June 2022 for transvaginal cervical emergency cerclages. STUDY ELIGIBILITY CRITERIA All studies on transvaginal cervical emergency cerclages with at least 5 patients and reporting survival were included. METHODS Included studies were assessed for quality and risk of bias with an adjusted Quality In Prognosis Studies tool. Random-effects meta-analyses and meta-regressions were performed for the primary outcome: survival. RESULTS Our search yielded 96 studies, incorporating 3239 women, including 14 studies with an expectant management control group, incorporating 746 women. Overall survival after cervical emergency cerclage was 74%, with a fetal survival of 88% and neonatal survival of 90%. Singleton and twin pregnancies showed similar survival, with a pregnancy prolongation of 52 and 37 days and a gestational age at delivery of 30 and 28 weeks, respectively. Meta-regression analyses indicated a significant inverse association between mean gestational age at diagnosis and pregnancy prolongation and no association between dilatation or gestational age at diagnosis and gestational age at delivery. Compared with expectant management, emergency cerclage significantly increased overall survival by 43%, fetal survival by 17% and neonatal survival by 22%, along with a significant pregnancy prolongation of 37 days and reduction in delivery at <28 weeks of gestation of 55%. These effects were more profound in singleton pregnancies than in twin pregnancies. CONCLUSION This systematic review indicates that, in pregnancies threatened by extreme premature birth because of cervical insufficiency, emergency cerclage leads to significantly higher survival, accompanied by significant pregnancy prolongation and reduction in delivery at <28 weeks of gestation, compared with expectant management. The mean gestational age at delivery was 30 weeks, independent of dilatation or gestational age at diagnosis. Survival was similar for singleton and twin pregnancies, implying that emergency cerclage should be considered in both.

Abstract
OBJECTIVE To compare the therapeutic effects of emergency cervical cerclage and expectant treatment in preterm birth due to cervical insufficiency in singleton pregnancy. METHODS A combination of subject words and free words was used to search major domestic and foreign databases. According to inclusion and exclusion criteria, 23 studies were included that met the criteria and quality evaluation and data extraction was carried out. The data were analyzed using STATA 15 and the reporting was done in reference to the list of Preferred Reporting Items for Systematic and Meta-Analyses. RESULTS Emergency cervical cerclage was superior to expectant treatment for the primary outcome of pregnancy prolongation (WMD = 5.752, 95% CI 5.194-6.311, 22 studies, N = 1435, I2 = 97.1%, P = 0.000). Cervical cerclage was also superior to expectant treatment for the secondary outcomes of neonatal birth weight (WMD = 1051.542, 95% CI 594.107-1508.977, 9 studies, N = 609, I2 = 96.4%, P = 0.000), neonatal Apgar 1' (WMD = 2.8720, 95% CI: 2.105-3.639, 11 studies, N = 716, I2 = 99.0%, P = 0.000), number of live births (OR = 6.018, 95% CI 2.882-12.568, 10 studies, N = 724, I2 = 55.3%, P = 0.000), deliveries after 32 weeks (OR = 8.030, 95% CI 1.38-46.892, 8 studies, N = 381, I2 = 85.9%, P = 0.021). deliveries after 34 weeks (OR = 15.91, 95% CI 5.92-42.77, 9 studies, N = 560, I2 = 59.6%, P = 0.000), number of vaginal deliveries (OR = 3.24, 95% CI 1.32-7.90, 8 studies, N = 502, I2 = 69.4%, P = 0.018), and number of neonatal survivals (OR = 9.300, 95% CI 3.472-24.910, 10 studies, N = 654, I2 = 80.5%, P = 0.000). No difference between emergency cervical cerclage and expectant treatment was found in patients with chorioamnionitis (OR = 1.85, 95% CI 0.602-4.583, 4 studies, N = 296, I2 = 16.3%, P = 0.273). CONCLUSION Before the 28th week of pregnancy, emergency cervical cerclage can significantly prolong the gestational week and improve the neonatal survival rate, compared to expectant treatment, in women with singleton pregnancies who have a dilated uterine orifice caused by cervical insufficiency.

The effectiveness of transabdominal cerclage placement via laparoscopy or laparotomy: a systematic review and meta-analysis. Am J Obstet Gynecol MFM 2023; 5:100757. [PMID: 36179967 DOI: 10.1016/j.ajogmf.2022.100757] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Accepted: 09/19/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVE Failure or technical impossibility to place a prophylactic transvaginal cerclage in women with cervical insufficiency justifies the need for an abdominal cerclage. In this systematic review and meta-analysis, we studied the obstetrical and surgical outcomes of laparoscopic and open laparotomy abdominal cerclage approaches performed before (interval) or during pregnancy. DATA SOURCES We performed a systematic literature search in PubMed, Embase, and the Cochrane Library for studies on laparoscopic and open laparotomy abdominal cerclage placement in February 2022. STUDY ELIGIBILITY CRITERIA All studies on laparoscopic or open laparotomy placement of an abdominal cerclage with at least 2 patients that reported on our primary outcomes were included. METHODS All included studies were assessed for quality and risk of bias with an adjusted Quality in Prognosis Study tool. Random effects meta-analyses were performed for the primary outcomes, namely fetal survival and gestational age at delivery. RESULTS Our search yielded 83 studies with a total of 3398 patients; 1869 of those underwent laparoscopic cerclage placement and 1529 underwent open laparotomy placements. No studies directly compared the 2 cerclage approaches. The survival (overall, 91.2%) and gestational age at delivery (overall, 36.6 weeks) were not statistically different between the approaches. For the procedure during pregnancy, the laparoscopic group showed significantly less blood loss >400 mL (0% vs 3%), a slightly lower procedure-related fetal loss (0% vs 1%), a shorter hospital stay but a longer operation duration than the open laparotomy group. For the interval cerclages, the laparoscopic group showed significantly fewer wound infections (0% vs 3%) and a shorter hospital stay than the open laparotomy group, but showed comparable offspring preterm birth and survival rates. CONCLUSION Based on indirect comparisons, the laparoscopic and open laparotomy abdominal cerclage placements at interval or during pregnancy produced similar outcomes in terms of survival and gestational age at delivery. There are some small differences in perioperative care, surgical complications, interventions, and complications during pregnancy. This implies that both methods of abdominal cerclage placement have high success rates and thus we cannot conclude that one of the methods is superior for the placement of an abdominal cerclage.

Relationship of Amniotic Fluid Sludge and Short Cervix With a High Rate of Preterm Birth in Women After Cervical Cerclage. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2022; 41:2687-2693. [PMID: 35106799 PMCID: PMC9790537 DOI: 10.1002/jum.15952] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 01/05/2022] [Accepted: 01/18/2022] [Indexed: 06/14/2023]
Abstract
OBJECTIVE We aims to determine the relationship of amniotic fluid sludge (AFS) and/or short cervical length (CL, ≤25 mm) with a high rate of preterm birth in women after cervical cerclage. METHODS A retrospective cohort study was conducted among singleton pregnancies after cervical cerclage between January 2018 and December 2021. A total of 296 patients who underwent transvaginal ultrasound to evaluate CL and the presence of AFS within 2 weeks after cerclage were included. Pregnancy outcome after cerclage was analyzed in accordance with the presence of AFS and CL ≤25 mm. RESULTS In patients with cerclage, AFS was an independent risk factor for preterm birth at <28 and <36 weeks but not for preterm birth at <32 weeks, and CL ≤25 mm was an independent risk factor for preterm birth at <28, <32, and <36 weeks. The Kaplan-Meier analysis showed that the association between the presence of AFS and short gestational age at delivery was statistically significant in women with CL ≤25 mm (log rank test, P = .000). The Cox regression analysis showed that these results remained significant after adjusting for confounding factors (P = .000). The negative linear relationships between AFS and CL (R = -0.454, P < .001) also explained the outcome. CONCLUSIONS AFS and short cervix have a direct effect on pregnancies after cerclage. Mid-trimester AFS can become a supplementary ultrasound index for detecting preterm birth after cerclage in pregnant women with a short cervix.

Endoscopic transabdominal cervical cerclage replacement after recurrent late miscarriage. BMJ Case Rep 2022; 15:e247757.

Abstract
Transabdominal cerclage (TAC) is a recognised treatment for recurrent spontaneous late miscarriage or preterm birth due to cervical weakness. This can be performed via an open procedure before and during pregnancy, or a laparoscopic technique preconception. Complications include cerclage failure and suture migration. We present a case highlighting these complications where laparoscopic removal of an open TAC and replacement led to two successful term deliveries. A woman in her thirties with a fibroid uterus, adenomyosis and a history of three spontaneous mid-trimester losses, had an open TAC at 13 weeks of gestation. Preterm premature rupture of the membranes occurred shortly after and at 18 weeks of gestation she underwent surgical evacuation of the uterus. Subsequent hysteroscopy confirmed migration of the cerclage through the cervical canal. We demonstrate the application of endoscopic gynaecological surgery to remove and replace the TAC with two successful term births by Caesarean section in the ensuing pregnancies.

Abstract
OBJECTIVES Cerclage operation is one of the most common obstetric controversies. The aim of this study was to compare the perinatal outcomes and placental inflammation of cerclage performed adherent and non-adherent to international guidelines. MATERIAL AND METHODS This study included all consecutive women with singleton deliveries who underwent cerclage. According to the current American College of Obstetricians and Gynecologists (ACOG) guideline, we designated our study population into two groups: the adherent-to-guideline and non-adherent groups. Each group was categorized into two groups according to cervical length (CL) at the time of cerclage (<2.0 cm vs. ≥2.0 cm). We evaluated the reasons for cerclage, maternal characteristics, perioperative variables, pregnancy and neonatal outcomes, and placental inflammatory pathology according to the criteria proposed by the Society of Pediatric Pathology. RESULTS Among 310 women with cerclage, we excluded patients (n = 21) with indicated preterm delivery (PTD), major fetal anomaly, fetal death in-utero, and missing information for reason of cerclage. We also excluded patients who underwent physical examination-indicated cerclage (n = 53) and with missing information of CL at the time of cerclage (n = 52). A total of 184 women were eventually analyzed. In women with CL < 2.0 cm, the non-adherent group showed similar PTD (<28 weeks, <34 weeks) and neonatal composite morbidity rates compared to the adherent-to-guideline group. However, in women with CL ≥ 2.0 cm, the non-adherent group manifested significantly higher PTD (<28 weeks; 16.7% vs. 4.4%, p = 0.04, <34 weeks; 23.8% vs. 5.8%, p = 0.006) and neonatal composite morbidity (20.5% vs. 5.9%, p = 0.028) rates than the adherent-to-guideline group despite similar perioperative variables and lower PTD history rates. The non-adherent group with CL ≥ 2 cm at the time of cerclage was also associated with severe histologic chorioamnionitis (p = 0.033). CONCLUSION Cerclage performed beyond the current guidelines in pregnant women with CL ≥ 2.0 cm may confer an additional risk of perinatal complications in association with severe placental inflammation.

Outcomes after transabdominal cerclage in twin pregnancy with previous unsuccessful transvaginal cerclage. PLoS One 2020; 15:e0232463. [PMID: 32353024 PMCID: PMC7192486 DOI: 10.1371/journal.pone.0232463] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2020] [Accepted: 04/15/2020] [Indexed: 11/18/2022] Open
Abstract
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.

History-indicated cervical cerclage in management of twin pregnancy. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2019; 54:517-523.

Abstract
OBJECTIVE Cervical cerclage, when performed in twin gestation, has been reported to be associated with poor outcome. However, the role of first-trimester history-indicated cerclage among women with a twin pregnancy and a history of preterm birth has not been evaluated. The aim of this study was to assess pregnancy outcomes among women with a twin pregnancy who underwent first-trimester history-indicated cervical cerclage compared with outcomes in those managed expectantly. METHODS This was a retrospective matched case-control study. The study group comprised all women with a twin pregnancy who had undergone first-trimester history-indicated cerclage during the period 2006 to 2017 at Hadassah-Hebrew University Medical Center. A control group of women with a twin pregnancy who were managed expectantly was established by matching age, history of spontaneous preterm birth (20-36 weeks' gestation) and year of delivery. Pregnancy and delivery characteristics and neonatal outcomes were compared between the two groups. RESULTS Data from 82 women with a twin gestation were analyzed, of whom 41 underwent first-trimester history-indicated cerclage and 41 were matched controls who were managed expectantly. Gestational age at delivery was higher in the cerclage group than in those managed expectantly (median 35 vs 30 weeks; P < 0.0001). Rates of spontaneous preterm birth before 24 weeks (2.4% vs 19.5%; odds ratio (OR), 0.10 (95% CI, 0.01-0.87); P = 0.03), before 28 weeks (12.2% vs 34.1%; OR, 0.27 (95% CI, 0.09-0.84); P = 0.03), before 32 weeks (22.0% vs 56.1%; OR, 0.22 (95% CI, 0.08-0.58); P = 0.003) and before 34 weeks (34.1% vs 82.9%; OR, 0.11 (95% CI, 0.04-0.30); P < 0.0001) were significantly lower in the cerclage group than in the control group. Median birth weight was higher in the cerclage group (2072 g vs 1750 g; P = 0.003), with lower rates of low birth weight (< 2500 g) (65.0% vs 89.4%; P = 0.001) and very low birth weight (< 1500 g) (21.3% vs 37.9%; P = 0.03) than in the group managed expectantly. Rates were also lower in the cerclage group for stillbirth, admission to the neonatal intensive care unit, respiratory distress syndrome, intraventricular hemorrhage, necrotizing enterocolitis, sepsis, neonatal mortality and composite adverse neonatal outcome. CONCLUSIONS History-indicated cerclage performed in the first trimester, as compared with expectant management, in women with a twin pregnancy had an overall positive effect on pregnancy and neonatal outcomes. These findings suggest the need for adequate randomized trials on cerclage placement in this subset of women. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
BACKGROUND Twin pregnancies with short mid-trimester cervical length have a high rate of preterm births. OBJECTIVES To compare combined treatment of Arabin cerclage pessary, and intravaginal micronized progesterone to conservative treatment for the prevention of preterm births in twins pregnancies with short cervical length in second trimester of pregnancy. METHODS A retrospective study that compared twin pregnancies with short ≤25mm cervix in second trimester 16-28 gestational weeks treated with combined treatment of Arabin cervical pessary and intravaginal micronized progesterone 200mg TID to a control group with conservative treatment for the prevention of preterm. RESULTS The treatment group included 32 patients and the control group 26 patients. Average week at admission was 23 ± 2.2 vs 25 ±3.1 weeks, average cervical length at admission 14.1 ± 2.2 mm vs 13 ±2.1 mm respectively. Average week of delivery 34.4 ±3.9 vs. 33.4 ±4.1, p=0.6 and incidence of delivery ≤28weeks was 9.4% vs. 34% p=0.04. CONCLUSIONS The treatment group had a lower incidence of preterm birth before 28 weeks. Further prospective studies are needed to assess preterm birth prevention treatments efficacy and the use of Arabin cervical pessary in twins.

Abstract
BACKGROUND Cervical cerclage is a well-known surgical procedure carried out during pregnancy. It involves positioning of a suture (stitch) around the neck of the womb (cervix), aiming to give mechanical support to the cervix and thereby reduce risk of preterm birth. The effectiveness and safety of this procedure remains controversial. This is an update of a review last published in 2012. OBJECTIVES To assess whether the use of cervical stitch in singleton pregnancy at high risk of pregnancy loss based on woman's history and/or ultrasound finding of 'short cervix' and/or physical exam improves subsequent obstetric care and fetal outcome. SEARCH METHODS We searched Cochrane Pregnancy and Childbirth's Trials Register (30 June 2016) and reference lists of identified studies. SELECTION CRITERIA We included all randomised trials of cervical suturing in singleton pregnancies. Cervical stitch was carried out when the pregnancy was considered to be of sufficiently high risk due to a woman's history, a finding of short cervix on ultrasound or other indication determined by physical exam. We included any study that compared cerclage with either no treatment or any alternative intervention. We planned to include cluster-randomised studies but not cross-over trials. We excluded quasi-randomised studies. We included studies reported in abstract form only. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion. Two review authors independently assessed risk of bias and extracted data. We resolved discrepancies by discussion. Data were checked for accuracy. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS This updated review includes a total of 15 trials (3490 women); three trials were added for this update (152 women). Cerclage versus no cerclageOverall, cerclage probably leads to a reduced risk of perinatal death when compared with no cerclage, although the confidence interval (CI) crosses the line of no effect (RR 0.82, 95% CI 0.65 to 1.04; 10 studies, 2927 women; moderate quality evidence). Considering stillbirths and neonatal deaths separately reduced the numbers of events and sample size. Although the relative effect of cerclage is similar, estimates were less reliable with fewer data and assessed as of low quality (stillbirths RR 0.89, 95% CI 0.45 to 1.75; 5 studies, 1803 women; low quality evidence; neonatal deaths before discharge RR 0.85, 95% CI 0.53 to 1.39; 6 studies, 1714 women; low quality evidence). Serious neonatal morbidity was similar with and without cerclage (RR 0.80, 95% CI 0.55 to 1.18; 6 studies, 883 women; low-quality evidence). Pregnant women with and without cerclage were equally likely to have a baby discharged home healthy (RR 1.02, 95% CI 0.97 to 1.06; 4 studies, 657 women; moderate quality evidence).Pregnant women with cerclage were less likely to have preterm births compared to controls before 37, 34 (average RR 0.77, 95% CI 0.66 to 0.89; 9 studies, 2415 women; high quality evidence) and 28 completed weeks of gestation.Five subgroups based on clinical indication provided data for analysis (history-indicated; short cervix based on one-off ultrasound in high risk women; short cervix found by serial scans in high risk women; physical exam-indicated; and short cervix found on scan in low risk or mixed populations). There were too few trials in these clinical subgroups to make meaningful conclusions and no evidence of differential effects. Cerclage versus progesteroneTwo trials (129 women) compared cerclage to prevention with vaginal progesterone in high risk women with short cervix on ultrasound; these trials were too small to detect reliable, clinically important differences for any review outcome. One included trial compared cerclage with intramuscular progesterone (75 women) which lacked power to detect group differences. History indicated cerclage versus ultrasound indicated cerclageEvidence from two trials (344 women) was too limited to establish differences for clinically important outcomes. AUTHORS' CONCLUSIONS Cervical cerclage reduces the risk of preterm birth in women at high-risk of preterm birth and probably reduces risk of perinatal deaths. There was no evidence of any differential effect of cerclage based on previous obstetric history or short cervix indications, but data were limited for all clinical groups. The question of whether cerclage is more or less effective than other preventative treatments, particularly vaginal progesterone, remains unanswered.

Abstract
BACKGROUND The physiological changes associated with pregnancy may predispose pregnant women to pulmonary edema. Other known causes of pulmonary edema during pregnancy include tocolytic drugs, preeclampsia, eclampsia, and peripartum cardiomyopathy. METHODS We describe a rare case of pulmonary edema caused by takotsubo cardiomyopathy in a pregnant woman at 14 weeks of gestation who was undergoing emergency transvaginal cervical cerclage. RESULTS Intraoperative chest radiography revealed severe pulmonary edema and echocardiography indicated moderate left ventricular dysfunction with akinesia of the mid to apical left ventricular wall segment, which is reflective of takotsubo cardiomyopathy. CONCLUSION With early detection and appropriate management, the patient was stabilized in a relatively short period of time. Based on her clinical signs and symptoms, we suspect that the pulmonary edema was caused by takotsubo cardiomyopathy.

Abstract
BACKGROUND Historically, Actinomyces infection has been associated primarily with the intrauterine device. Recently, case reports associating Actinomyces with other implants have been described, including nonwoven polypropylene mesh used for urethral slings and Mersilene cerclage placements. However, there are no reported cases of chronic Actinomyces infections associated with retained Mersilene cerclage. CASE A 51-year-old woman, gravida 3, para 3, presented with a 10-year history of vaginal discharge and Actinomyces identified on endometrial biopsy. After failing medical treatment and undergoing a hysterectomy, the patient was found to have a retained Mersilene cerclage. CONCLUSION This is the first case to report persistent Actinomyces infection with a retained Mersilene cerclage. No current recommendations exist for assessing full removal of cerclage. Clinicians should have a high suspicion of Actinomyces infection in a patient who presents with persistent vaginal discharge and history of cerclage placement.

Effect of cervical cerclage on rate of cervical shortening. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2015; 46:718-723. [PMID: 25652890 DOI: 10.1002/uog.14810] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/17/2014] [Revised: 01/13/2015] [Accepted: 01/29/2015] [Indexed: 06/04/2023]
Abstract
OBJECTIVE Although cerclage has been shown to reduce the risk of recurrent preterm birth in a high-risk patient population, the mechanism by which this occurs is not well understood. Our objective was to evaluate whether cerclage affects the rate of cervical shortening taking into account exposure to 17-hydroxyprogesterone and vaginal progesterone. METHODS This was a retrospective cohort study of women who had serial cervical length measurements due to a history of spontaneous preterm delivery. Demographic data, obstetric history, progesterone administration, delivery information and serial cervical length measurements were collected. The rate of cervical shortening was compared in women with and without cerclage. Subgroup analyses were performed to compare rates of cervical shortening by indication for cerclage (history indicated vs ultrasound indicated) and outcome in the current pregnancy (cerclage vs no cerclage among those who delivered preterm). RESULTS A total of 414 women were included of whom 32.4% (n = 134) had a cerclage. There was no difference in the rate of cervical shortening between the cerclage (0.8 mm/week) and no-cerclage (1.0 mm/week, P = 0.43) groups. The rates of cervical shortening among history-indicated and ultrasound-indicated cerclage groups were similar (0.9 vs 1.3 mm/week, respectively, P = 0.2). Among patients with a preterm delivery in the index pregnancy, the rates of cervical shortening among those with (1.31 mm/week) and without (1.28 mm/week, P = 0.78) cerclage were also similar. CONCLUSION Cervical shortening among women with cerclage occurs at a similar rate to that among women without a cerclage, regardless of indication for cerclage or pregnancy outcome.

Removal versus retention of cerclage in preterm premature rupture of membranes: a randomized controlled trial. Am J Obstet Gynecol 2014; 211:399.e1-7.

Abstract
OBJECTIVE The decision of whether to retain or remove a previously placed cervical cerclage in women who subsequently rupture fetal membranes in a premature gestation is controversial and all studies to date are retrospective. We performed a multicenter randomized controlled trial of removal vs retention of cerclage in these patients to determine whether leaving the cerclage in place prolonged gestation and/or increased the risk of maternal or fetal infection. STUDY DESIGN A prospective randomized multicenter trial of 27 hospitals was performed. Patients included were those with cerclage placement at ≤23 weeks 6 days in singleton or twin pregnancies, with subsequent spontaneous rupture of membranes between 22 weeks 0 days and 32 weeks 6 days. Patients were randomized to retention or removal of cerclage. Patients were then expectantly managed and delivered only for evidence of labor, chorioamnionitis, fetal distress, or other medical or obstetrical indications. Management after 34 weeks was at the clinician's discretion. RESULTS The initial sample size calculation determined that a total of 142 patients should be included but after a second interim analysis, futility calculations determined that the conditional power for showing statistical significance after randomizing 142 patients for the primary outcome of prolonging pregnancy was 22.8%. Thus the study was terminated after a total of 56 subjects were randomized with complete data available for analysis, 32 to removal and 24 to retention of cerclage. There was no statistical significance in primary outcome of prolonging pregnancy by 1 week comparing the 2 groups (removal 18/32, 56.3%; retention 11/24, 45.8%) P = .59; or chorioamnionitis (removal 8/32, 25.0%; retention 10/24, 41.7%) P = .25, respectively. There was no statistical difference in composite neonatal outcomes (removal 16/33, 50%; retention 17/30, 56%), fetal/neonatal death (removal 4/33, 12%; retention 5/30, 16%); or gestational age at delivery (removal mean 200 days; retention mean 198 days). CONCLUSION Statistically significant differences were not seen in prolongation of latency, infection, or composite neonatal outcomes. However, there was a numerical trend in the direction of less infectious morbidity, with immediate removal of cerclage. These findings may not have met statistical significance if the original sample size of 142 was obtained, however they provide valuable data suggesting that there may be no advantage to retaining a cerclage after preterm premature rupture of membranes and a possibility of increased infection with cerclage retention.

Abstract
The Perinatal morbidity and mortality associated with pre-term delivery is well known. Cervical incompetence or short cervix is a risk factor for the condition and cervical cerclage is the management option for such cases. The objective of the study was to determine the frequency of operative morbidities of cervical cerclage. All women undergoing cervical cerclage from April 2007 to December 2009 at the Aga Khan University Hospital served as the study subjects. Findings suggested that the risk of developing ruptured membranes after cervical cerclage was 10% and that of pregnancy loss was 8.6%. The risk of cerclage-associated complications like rupture of membranes, bleeding and chorioamnionitis was small. The risk of delivery before 34 weeks of gestation was 15.7%.

BACKGROUND Cervical cerclage is a well-known surgical procedure carried out during pregnancy. It involves positioning of a suture (stitch) around the neck of the womb (cervix), aiming to give a mechanical support to the cervix and thereby reducing the risk of preterm birth. The effectiveness and safety of this procedure remains controversial. OBJECTIVES To assess whether the use of cervical stitch in singleton pregnancy at high risk of pregnancy loss based on a woman's history and/or ultrasound finding of 'short cervix' and/or physical exam improves subsequent obstetric care and fetal outcome. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 October 2011) and reference lists of identified studies. SELECTION CRITERIA We included all randomised trials of cervical suturing in singleton pregnancies carried out when pregnancy was considered to be at sufficiently high risk of pregnancy loss for cerclage to be potentially indicated. We included any study that compared cerclage with either no treatment or any alternative intervention. DATA COLLECTION AND ANALYSIS Three review authors independently assessed trials for inclusion. Two review authors independently assessed risk of bias and extracted data. Data were checked for accuracy. MAIN RESULTS We included 12 trials (involving 3328 women). When cerclage was compared with no treatment, there was no statistically significant difference in perinatal deaths (8.4% versus 10.7%) (risk ratio (RR) 0.78; 95% confidence interval (CI) 0.61 to 1.00; eight trials, 2391 women) and neonatal morbidity (9.6% versus 10.2%) (RR 0.95; 95% CI 0.63 to 1.43; four trials, 818 women), despite significant reduction in preterm births (average RR 0.80; 95% CI 0.69 to 0.95; nine trials, 2898 women). Cervical cerclage was associated with the higher rate of maternal side effects (vaginal discharge and bleeding, pyrexia) (average RR 2.25; 95% CI 0.89 to 5.69; three trials, 953 women). Caesarean section rates were significantly higher after cervical cerclage (RR 1.19; 95% CI 1.01 to 1.40; 8 trials, 2817 women).There was no evidence of any important differences across all prespecified clinical subgroups (history-indicated, ultrasound-indicated)One study that compared cerclage with weekly intramuscular injections of 17 α-hydroxyprogesterone caproate in women with a short cervix detected by transvaginal ultrasound, failed to reveal any obvious differences in obstetric and neonatal outcomes between the two management strategies.Two studies compared the benefits of performing cerclage based on previous history with cerclage, only if the cervix was found to be short on transvaginal ultrasound. There was no significant difference in any of the primary and secondary outcomes. AUTHORS' CONCLUSIONS Compared with no treatment, cervical cerclage reduces the incidence of preterm birth in women at risk of recurrent preterm birth without statistically significant reduction in perinatal mortality or neonatal morbidity and uncertain long-term impact on the baby. Ceasarean section is more likely in women who had cervical suture inserted during pregnancy.The decision on how best to minimise the risk of recurrent preterm birth in women at risk, either because of poor history of a short or dilated cervix, should be 'personalised', based on the clinical circumstances, the skill and expertise of the clinical team and, most importantly, woman's informed choice.

Abstract
We report our experience with a unilateral congenital dislocation of the knee associated with a developmental dysplasia of the hip on the same side. Our case is a good example of congenital dislocation of the knee caused by abnormal intrauterine pressure leading to this type of congenital postural deformity. To our knowledge this is the first case of congenital dislocation of the knee reported after cervical cerclage of an incompetent cervix to prevent a pre-term delivery. The Pavlik Harness was used to treat the knee and the hip at the same time with a satisfactory result after 20 months of follow-up.

Abstract
BACKGROUND A cervical cerclage is often placed for women with cervical shortening or insufficiency. There are early and late complications of cervical cerclage placement, but they rarely involve the lower urinary tract. We present a case of a lower urinary tract complication from this procedure presenting as recurrent urinary tract infections. CASE A 43-year-old woman with a history of cerclage placement during her second pregnancy (10 years prior) presented with recurrent urinary tract infections and hematuria. Radiologic imaging and cystoscopy revealed a 2-cm bladder stone attached to suture that was subsequently removed during cystoscopy. CONCLUSION Retained suture from a cervical cerclage can act as a nidus for bladder stone formation.

Abstract
OBJECTIVE Efficacy of emergency cerclage commensed in the second trimester is a controversial issue. In this study, we aimed to assess the success and associated complications of emergency cerclage in patients with cervical dilatation in the second trimester. MATERIAL AND METHODS In this retrospective study, medical records of 75 pregnant women who had clinically and ultrasonographically confirmed cervical dilatation in the second trimester who had undergone cervical cerclage were analyzed. Pregnancy prolongation was the main outcome measure. RESULTS Seventy-five women were included to the study. Mean age was 27 and mean gravidity of the patients was three. Mean cervical length was 28.5 mm (12-41 mm). The rate of spontaneous abortion, immature deliveries, prematurity and deliveries after 34 weeks were 2.7% (n = 2), 8% (n = 6), 12 (n = 9) and 77.7 (n = 58), respectively. Fetal survival rate was 89.1% (n = 65). Serious vaginal bleeding from the suture area was noted in two patients (2.6%). No postoperative complications occurred. CONCLUSION Emergency cerclage is a simple surgical procedure with lower complication rates and can effectively prolong gestation to viability. It can be considered as a useful measure for patients with evidence of cervical changes in the second trimester.

Abstract
OBJECTIVE The aim of this study was to determine whether intra-amniotic (IA) sludge, a sonographic finding of hyperechoic matter in the amniotic fluid close to the internal cervical os, is associated with preterm delivery in patients with cervical cerclage. METHODS A retrospective cohort study of patients who had undergone McDonald cerclage between January 1997 and December 2004 was conducted. Transvaginal ultrasound examinations had been performed at 14-28 weeks of gestation, and the ultrasound images were assessed by three reviewers (blinded to patient outcome) to determine the presence or absence of IA sludge. The primary outcome studied was the gestational age at delivery. RESULTS A total of 177 patients who had undergone cervical cerclage, and for whom adequate records were available, were identified. Sixty had sonographic evidence of IA sludge (Group 1) and 117 had absence of IA sludge (Group 2). There was no significant difference in the mean gestational age at delivery between the two groups (36.4 ± 4.0 vs. 36.8 ± 2.9 weeks, P = 0.53), and no statistical difference in the rate of preterm delivery at < 28 (6.7% vs. 1.7%, P = 0.18), < 30 (6.7% vs. 3.4%, P = 0.45), < 32 (8.3% vs. 6.8%, P = 0.77) or < 36 (16.7% vs. 19.7%, P = 0.69) weeks of gestation. CONCLUSION Intra-amniotic sludge on ultrasound is not associated with an increased risk of preterm delivery in patients with cervical cerclage.

Abstract
Cervicovaginal fistula is a recognized complication of induced mid-trimester termination of pregnancy, but more recently it has also been recognized as representing a complication of prior cervical cerclage. We report the ultrasound findings of prolapse of the amniotic sac through a cervicovaginal fistula in a woman with prior cervical cerclage. A woman with cervical incompetence and prior failed McDonald cerclage presented for prophylactic Shirodkar cerclage. Before the procedure, transvaginal ultrasonography revealed a live intrauterine pregnancy at 14 weeks' gestation. Upon further ultrasound examination, the amniotic sac appeared to protrude through the posterior wall of the cervix into the vaginal vault. Pelvic examination verified prolapse of the amniotic sac through a cervicovaginal fistula. The patient underwent an uncomplicated dilatation and evacuation. Women with a history of cervical cerclage are at risk for the development of cervicovaginal fistula, the detection of which is important to prevent potential morbidity.

Abstract
OBJECTIVE To describe labor outcomes in women who had a Shirodkar cerclage placed during pregnancy and removed before labor. METHODS A review was conducted of 69 patients with a singleton pregnancy and a Shirodkar cervical cerclage placed before 24 weeks' gestation. Indications for cerclage were history indicated, ultrasound indicated or physical examination indicated. RESULTS The mean time from cerclage removal to delivery was 9.4 +/- 8.8 days. The overall cesarean delivery rate was 18.8%, with the majority (9 of 13) being for fetal indications. Two (2.9%) patients had a uterine rupture of an unscarred uterus and 2 (2.9%) patients had an umbilical cord prolapse. Four (5.8%) patients had a cervical laceration requiring repair. CONCLUSION Patients with a Shirodkar cerclage placed and removed during the index pregnancy appear to have a higher than expected rate of cesarean delivery for fetal indications and complications associated with significant neonatal morbidity including uterine rupture and cord prolapse.

Abstract
UNLABELLED The aim of this systematic review was to compare pregnancy outcomes and cerclage-related complications of ultrasound-predicated versus history-predicated cerclage in patients at risk of cervical insufficiency due to a history of preterm delivery (PTD). A structured search was performed in PubMed, Embase, and the Cochrane Library to identify potentially relevant articles from January 1980 through July 2007. Studies were included if ultrasound-predicated cerclage was compared to history-predicated cerclage in women with a singleton gestation and a history of PTD. The PubMed, Embase, and Cochrane search yielded 537, 643, and 42 articles, respectively. In addition, 1194 "Related articles" (PubMed) and 87 "Cited in/cited by" (ISI-WOS) from all potentially relevant articles were assessed. After critical evaluation for relevance and quality, 6 articles remained. Five of the 6 included studies showed no differences in pregnancy outcome (PTD or pregnancy loss <24 weeks) between the ultrasound-predicated and the history-predicated cerclage groups. In 1 prospective cohort study, PTD below 30 weeks was significantly lower in the ultrasound group. The included studies showed that in the ultrasound group, 40% to 68% of the patients did not require cerclage. The majority of studies provided insufficient data to draw conclusions regarding cerclage-related complications. In conclusion, using ultrasound to identify women at risk of cervical insufficiency because of a history of PTD reduces cerclage rates and results in similar pregnancy outcomes as cerclage placement on the basis of history alone. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After reading this article, the reader should be able to identify his or her own management of women with prior history of preterm delivery with respect to the possible use of cerclage, design a diagnostic strategy for his or her own patients to determine whether history or ultrasound-based decision making is appropriate in the practice setting, and translate best-practices with respect to definition of cervical shortening in his or her own practice.

Abstract
BACKGROUND Women with a history of pregnancy loss in the second trimester are often diagnosed with cervical insufficiency and are treated with cervical cerclage. We present an unusual complication of this procedure that mimicked preterm rupture of membranes. CASE A 38-year-old woman with a history of cervical conization, loss of a triplet pregnancy at 22 weeks, and one early spontaneous abortion underwent cervical cerclage placement during her third pregnancy. She developed an intermittent vesicovaginal fistula 2 weeks after the procedure that mimicked preterm premature rupture of membranes. Only after the urine loss became heavy and continuous 10 weeks later was the diagnosis of vesicovaginal fistula made. CONCLUSION Obstetricians should recognize that cerclage placement may result in unusual urinary tract injury.

Abstract
BACKGROUND To evaluate the outcome of midtrimester emergency cerclage with or without bulging of membranes. METHODS A retrospective cohort study of 99 women who underwent emergency second trimester cerclage (16-27 gestational weeks). In 75 women the cervix was dilated and effaced but without bulging of membranes (group 1), and in 24 women the dilation and effacement of the cervix were accompanied by bulging of membranes into the vagina in an hourglass formation (group 2). McDonald technique was applied in all patients. RESULTS Prolongation of pregnancy was significantly longer in group 1 compared to group 2 (14.3+/-6.5 vs 9.3+/-4.8 weeks, p=0.007). The mean gestational age at delivery was significantly higher in group 1 compared to group 2 (34.6+/-4.6 vs 29.5+/-3.2 weeks, p=0.001). The incidence of chorioamnionitis was higher in group 2 compared to group 1 but statistically insignificant (25% vs 15%, p=0.2). The overall neonatal survival was 83% (82 out of 99 neonates), without statistical difference between the two groups (86% in group 1 and 71% in group 2, p=0.2). CONCLUSIONS Favorable neonatal outcome may be accomplished in patients with cervical incompetence in the second trimester of pregnancy following cervical emergency suturing even performed when the membranes are bulging through the cervix into the vagina.

Abstract
OBJECTIVE To evaluate the risks of cerclage retention in the setting of preterm premature rupture of membranes (PPROM). STUDY DESIGN Patients from 1995-2003 with PPROM at < or = 32 weeks and cerclage were studied via chart review. Only patients who received > 48 hours of antibiotics and a course of corticosteroids and who delivered after 24 weeks' gestation were included, RESULTS Of 23 cases, 17 (74%) had a retained cerclage (cerclage not removed within the first 24 hours of admission), and 6 (26%) had the cerclage removed within 24 hours of admission. Gestational age at PPROM was earlier in the retained cerclage group (26.1 +/- 3.3 vs. 29.3 +/- 2.9 weeks, p = 0.04). There was no difference in the rates of chorioamnionitis (50% vs. 52%, p = 0.9) or neonatal death due to sepsis (17% in each, p = 0.55) between the 2 groups. CONCLUSION Although this study did not have sufficient power to detect these differences, cerclage retention in patients with PPROM managed with both corticosteroids and antibiotics was not associated with either increased maternal morbidity or neonatal mortality. Severe prematurity and not a retained cerclage may be a greater contributor to neonatal mortality due to sepsis. Future research would require a multicenter, randomized trial that allows a greater sample size to elucidate optimal management in these patients.

Abstract
OBJECTIVE To estimate benefits and risks of transabdominal cervicoisthmic cerclage in women with cervical insufficiency in whom transvaginal cerclage is considered surgically unfeasible. METHODS This was an observational cohort study with historical controls of 101 pregnancies after transabdominal cervicoisthmic cerclage in 101 women with a classic history of cervical insufficiency and severe cervical defects precluding transvaginal cerclage. RESULTS Median gestational age at elective transabdominal cerclage (n = 95) was 14 (range 12-16) weeks and at emergency cerclage (n = 6) was 18 (range 17-22) weeks. Perioperative complications were blood loss 500 mL or more (n = 3) and rupture of membranes (n = 2). Patients were delivered by cesarean. Before cerclage 76% (95% confidence interval [CI] 70.2-81.1%) of births occurred before 32 weeks of gestation; total neonatal survival was 27.5% (95% CI 22.5-33.8%). After transabdominal cervicoisthmic cerclage 7% (95% CI 2.9-13.9%) of births took place before 32 weeks of gestation, and total neonatal survival was 93.5% (95% CI 85.5-96.6%). CONCLUSION In women with a classic history of cervical insufficiency and a traumatized cervix that precludes transvaginal cerclage, transabdominal cervicoisthmic cerclage is associated with successful outcome in the absence of procedure-related major complications.

Evaluation of effectiveness of prophylactic cerclage of a short cervix according to interleukin-8 in cervical mucus. Am J Obstet Gynecol 2006; 194:14-9.

Abstract
OBJECTIVE This study was undertaken to compare rates of preterm delivery according to cervical mucus interleukin-8 (IL-8) among women who underwent cerclage because of a short cervix. STUDY DESIGN This retrospective study included 16,508 patients whose cervical length and cervical mucus IL-8 concentrations were measured between 20 and 24 weeks. A short cervix was defined by a length of 25 mm or less, whereas IL-8 concentrations exceeding 360 ng/mL were considered high. Whether to perform cerclage was decided by clinicians without consideration of IL-8 concentrations. RESULTS Among all subjects, a significantly smaller percentage of subjects avoided delivery before 37 weeks when cervical mucus IL-8 was elevated (P = .0302) or the cervix was short (P < .0001). Among patients with a short cervix, preterm delivery was more likely when cervical mucus IL-8 was elevated. Overall, risk of preterm delivery in patients with a short cervix did not differ between those undergoing and not undergoing cerclage. However, among patients with a short cervix, those with normal IL-8 concentrations in cervical mucus were less likely to have preterm delivery if they underwent cerclage (before 37 weeks, 33% vs 54.5%, P = .01; before 34 weeks, 4% vs 13.6%, P = .03). In contrast, when cervical mucus IL-8 was high, delivery before 37 weeks was more likely with than without cerclage (78% vs 54.1%, P = .03). CONCLUSION With normal cervical mucus IL-8, cerclage treatment for cervical shortening may reduce the rate of preterm delivery, but with elevated cervical mucus IL-8 cerclage may be harmful.

Abstract
BACKGROUND There have been relatively few reports on the outcome of cervical cerclage performed in non-tertiary centres. The aim of this study was to determine the pregnancy complications and outcome in patients following cervical cerclage. METHODS Seventy-one patients who had 103 pregnancies and underwent cervical cerclage at Women's Hospital, Aba over a ten-year period were reviewed. The diagnosis of cervical incompetence was made from the history in 90.6% of cases and also in some cases by hysterosalpingography and ultrasonography. RESULTS The Shirodkar (65%) and McDonald (35%) techniques were employed and 10.7% of cases were done as emergency procedures. The more common post-insertion complications were urinary tract infection (50.4%), preterm rupture of membranes (20.4%) and vulvovaginitis (14.6%). Common labour associated complications were antepartum haemorrhage, perineal/cervical tears and malpresentations. The preterm birth rate was 32%. Term births accounted for 68% of the deliveries. The overall fetal salvage rate was 92.2%. Antepartum haemorrhge was a significant indication for caesarean section delivery. The perinatal mortality was 63.2 per 1000 and there was no maternal death. CONCLUSION The high fetal salvage rate of 92.2% justifies the procedure of cervical cerclage.

Abstract
OBJECTIVE The aim of this study was to evaluate the efficacy and safety of a noninvasive cerclage pessary in the management of cervical incompetence. METHODS This is a prospective cohort study of all pregnant women treated for cervical incompetence during a 4-year period. Women with known risk factors for preterm delivery had transvaginal ultrasonography every 2-3 weeks after 17-19 weeks of gestation. Those with progressive shortening of cervix diagnosed before 30 weeks were treated with a cerclage pessary when the cervical length was < or = 25 mm. The pessary was electively removed at 34-36 weeks. The course and outcome of pregnancy were recorded. RESULTS Thirty-two women were treated with a cerclage pessary. There were nine twin and two triplet pregnancies. Fifteen (47%) had two or more risk factors for preterm delivery. The mean gestational age at cerclage was 23 (17-29) weeks, cervical length 17 (5-25) mm. Two women required delivery before the onset of labor due to severe intrauterine growth restriction and one due to HELLP syndrome. These were excluded from further analysis. In the remaining 29 women, the interval between cerclage and delivery was 10.4 (2-19) weeks, mean gestational age at delivery 34 (22-42) weeks, and birth weight 2,255 (410-4,045) g. Thirteen (45%) women delivered before 34 weeks. There were a total of 35 live-born infants and four intrapartum fetal deaths (all between 22 and 25 weeks gestation). All women complained of increased vaginal discharge, but no other significant complications were observed that could be attributed to the use of pessary. CONCLUSION Cerclage pessary may be useful in the management of cervical incompetence. Whether it can be a noninvasive alternative to surgical cerclage merits further investigation.

Abstract
Transabdominal cerclage is a recognised treatment for cervical weakness with a history of recurrent mid-trimester loss and a failed elective vaginal suture. The emergence of dual pathology, such as antiphospholipid syndrome and bacterial vaginosis, is associated with an increased risk of preterm delivery (RR 2.34, 95% CI 1.15-5.8). The first 40 cases are described where strict adherence to an investigation protocol and consistent treatment plan has been implemented.

Abstract
OBJECTIVE The study was aimed to assess the impact of obstetric risk factors for preterm delivery among women with MacDonald cerclage performed due to cervical incompetence. STUDY DESIGN A cohort study was conducted including all patients with MacDonald cerclage performed at 12-14 weeks gestation due to cervical incompetence (n = 793). Deliveries occurred between the years 1988 and 2002 in a University Medical Center. A multiple linear regression model was used to assess the impact of maternal characteristics as well as pregnancy complications on the length of pregnancy. RESULTS The following factors were found to be associated with preterm delivery among these patients, in the univariate analysis: nulliparity, fertility treatments, severe preeclampsia, second-trimester bleeding, premature rupture of membranes (PROM), chorioamnionitis and placental abruption. Using a multiple linear regression model, with backward elimination, the impact of these variables on the length of pregnancy was assessed (R(2) = 0.33, p < 0.001). The mean gestational age at birth among patients without risk factors was 38.1. Second-trimester bleeding reduced gestational age by 6.4 weeks, chorioamnionitis by 5.6 weeks, placental abruption by 5.1 weeks, PROM by 3.2 weeks and severe preeclampsia by 2.4 weeks. CONCLUSIONS Second-trimester bleeding, chorioamnionitis, placental abruption, PROM and severe preeclampsia are ominous signs for preterm delivery among patients with MacDonald cerclage performed due to cervical incompetence.

Abstract
OBJECTIVE To examine whether cervical cerclage after the first delivery prolongs the inter-delivery interval in delayed interval deliveries. STUDY DESIGN We identified 66 case reports and case series of delayed interval delivery published between 1880 and 2002. We selected seven case series that identified all cases of delayed interval delivery in their institutions during a specified period. RESULTS Despite routine use of broad-spectrum prophylactic antibiotics, the average incidence of clinical intrauterine infection after the first delivery was 36% (95% confidence interval (CI): 26-46%). The incidence of maternal sepsis was 4.9% (95% CI: 0.2-9.6%). Studies in which cerclage was infrequently used reported a shorter inter-delivery interval compared to studies where cerclage was used in all cases (median is equal to 9 days versus 26 days, respectively, P<0.001) despite similar gestational ages at the first delivery, types of antibiotics, tocolytics, and incidence of infection. After controlling for other factors, the use of cerclage did not significantly increase the risk of intrauterine infection (adjusted relative risk=1.1, 95% CI: 0.4-3.5). CONCLUSION Cervical cerclage after the first delivery is associated with a longer inter-delivery interval without increasing the risk of intrauterine infection.

Abstract
Cervical incompetence is defined as the inability to support a full-term pregnancy because of a functional or structural defect of the cervix. It is characterized clinically by acute, painless dilatation of the cervix usually in the mid-trimester culminating in prolapse and/or premature rupture of the membranes with resultant preterm and often previable delivery. Cervical cerclage has become the mainstay for the management of cervical incompetence, but remains one the more controversial surgical interventions in obstetrics. This article reviews the current state of the literature as regards the indications, contraindications, and techniques of cervical cerclage. This article also focuses in detail on 4 areas of controversy, namely transabdominal cerclage, cervical cerclage for a short cervix, the management of cerclage after preterm premature rupture of the membranes, and the utility of a second (salvage) cerclage.

Abstract
Cervical insufficiency is one of the risk factors for late spontaneous miscarriage and preterm labor. As cervical insufficiency can reoccur in the every subsequent pregnancy, there is a need for precise diagnostic modality and therapeutic procedure in order to reduce perinatal mortality and morbidity. Traditionally, the diagnosis of cervical insufficiency was made based on the patient's history. In this cases the intervention in the form of the cervical cerclage, was not found to be useful, i.e. perinatal mortality and morbidity remained unchanged. It is a similar situation in cervical insufficiency suspected based on hysterosalpingography and clinical examination. Recently, ultrasound, or more precisely transvaginal cervical assessment--cervicometry, was introduced in order to assess the morphological changes indicative for cervical insufficiency. In this literature review, we analyzed ultrasound based markers of cervical insufficiency, with their specificity, sensitivity, positive and negative predictive value, as well as usefulness of cervical cerclage in such cases.

Abstract
Fifty patients with cervical incompetence were randomised to have cervical cerclage either as inpatients, spending 3 days in hospital post-procedure on supervised bed rest or as outpatients spending the time at home on bed rest. Both groups had a clinical diagnosis of cervical incompetence and both had either McDonald or Shirodkar cerclage with mersilene tape. Both groups were given salbutamol tablets for tocolysis, postoperatively. There were no significant difference in the demographic variables between the groups such as previous cerclage, gestational age at insertion, parity and gestational age at delivery. There were also no significant differences in early complications such as bleeding. Most late complications were also not different, including the spontaneous abortion rate, premature rupture of membranes, cervical dystocia and preterm delivery. However, more patients in the outpatient group had premature contractions (26.1% vs. 4.3% P=0.0479). More patients in the inpatient group had a delivery of a live neonate, 86.9% vs. 78.3%, but the difference was not statistically significant. In conclusion, out patient cerclage appears to be a valid option, the higher rate of premature contraction in this group is not a cause for concern in view of the similar mean gestational age at delivery.

Abstract
Previously reported cases of spontaneous rupture of the kidney or ureter reflect underlying renal pathology and have been reported both spontaneously and in relationship to delivery, but not in relation to other operative procedures. A 27-year-old woman at 19 weeks' gestation developed severe right flank pain in the operating room immediately prior to cerclage placement. Postoperative renal ultrasound examination and intravenous pyelogram performed to evaluate persistent flank pain demonstrated renal pelvis rupture. No other renal abnormality was present. We postulated that increased urine flow from the fluid bolus for the spinal anesthetic precipitated the rupture.
