Laparoscopic transabdominal cerclage: new approach

Objective: To evaluate efficiency and safety of the new approach of laparoscopic cerclage.

Study design: Fifteen women were operated with our new technique. Their age ranged from 22 years to 35 years. Inclusion criteria included those with history of two or more second trimesteric abortions or early preterm labor. These women had at least two previous unsuccessful vaginal cerclage or vaginal insertion of cerclage is not possible because of congenitally short cervix, cervical conization or excessive cervical scarring.

Results: Twelve of the participants delivered vaginally with the removal of cerclage, two had CS due to breech presentation and the cerclage was left in place and the last one has surgical evacuation. No intraoperative or postoperative complications were encountered namely; excessive bleeding, injury of uterine vessels or postoperative peritonitis. No technical difficulties upon doing the procedure or cerclage removal were met apart from one case where removal of the vaginal stitch was not possible [incision was done in the cervix over the tape and the Mersilene tape was cut followed by repair of the cervical tissue using (00) Vicryl stitches].

Conclusion: The new approach for laparoscopic cerclage is a safe, effective and reasonable treatment after failure of vaginal cerclage.     

腹腔镜下子宫峡部环扎术

子宫峡部环扎术是治疗宫颈机能不全最主要的方法。对于反复经阴道环扎失败或宫颈解剖异常不能经阴道环扎的患者,可选择经腹腔镜子宫峡部环扎。腹腔镜子宫峡部环扎术可在非孕期或早孕期进行。孕中晚期发生胎儿异常需终止妊娠时可经剖腹或腹腔镜拆除缝线经后阴道分娩。足月妊娠则需要剖宫产终止妊娠。腹腔镜下子宫峡部环扎术是治疗宫颈机能不全的有效方法之一,但其是否能作为治疗宫颈机能不全的标准术式尚待多中心临床随机对照研究结果证实。     

Validity of indications for transabdominal cervicoisthmic cerclage for cervical incompetence

Objective: Our purpose was to review the indications for transabdominal cervicoisthmic cerlage to determine whether it is a valid alternative to transvaginal cerclage.Study design: A retrospective review of transabdominal cerclage patients at one institution form 1978 to 1994, analysis of the indications for the transabdominal rather than the vaginal approach, and evaluation of fetal outcomes was performed.Results: Twenty-three patients underwent 24 transabdominal cerclages. The primary indication for transabdominal cervicoisthmic cerclage was failed transvaginal cerclage in 14 patients and anatomic unsuitability for transvaginal cerclage in nine. Of the latter, five were a result of diethylstilbestrol exposure and four a result of cervical surgery. All patients were successfully delivered of one or more live babies (total 28, including two sets of twins). Two losses occurred, one after rupture of membranes at 21 weeks on the second pregnancy after cerclage placement and one intraoperative loss with herniation of the membranes. The live birth rate was 93%, compared with 18% salvage of pregnancies beyond the first trimester before the transabdominal cervicoisthmic cerclage procedure. Complications included blood loss requiring transfusion (four patients), although none of these occurred in the last 12 patients.Conclusion: We conclude that all the patients had a history compatible with incompetent cervix requiring a cerclage, and none were suitable candidates for a vaginal cerclage. We further conclude that with strict indications transabdominal cervicoisthmic cerclage offers a high rate of fetal salvage with a minimum of complications in patients with extremely poor obstetric histories because of cervical incompetence.     

Comparison of elective and empiric cerclage and the role of emergency cerclage

We describe the maternal, obstetric, and neonatal outcomes of patients undergoing elective, empiric, and emergency cervical cerclage at our institution in an attempt to determine predictive factors for adverse perinatal and maternal outcomes. A retrospective chart review was conducted on patients who underwent cervical cerclage placement over a 7-year time span. Of 55 charts, 40 contained complete peripartum data satisfactory for review; 7 elective, 15 empiric, and 18 emergency cerclages were analyzed. There was no perinatal mortality in the elective group, and 5/7 patients delivered at term. The empiric population experienced a 20% neonatal mortality; 6/15 gestations progressed to term. The perinatal mortality was 44% in the emergency group and 2/18 patients delivered at term. Relative to neonatal outcome, elective cerclage was statistically significantly better than emergent cerclage; there was no statistically significant difference between the elective and empiric groups nor between the empiric and emergent groups. This relatively small series with a large number of variables appeared to favor an elective procedure rather than an empiric one. Although emergent cerclage was associated with only a 56% neonatal survival, it did have value in some patients.     

腹腔镜下宫颈环扎术治疗宫颈机能不全16例临床分析

目的探讨腹腔镜下宫颈环扎术治疗宫颈机能不全的效果和安全性。方法对2008年8月至2011年12月中山大学附属第一医院妇科16例经阴道宫颈环扎手术失败和无法行经阴道宫颈环扎术的宫颈机能不全患者,在非孕期行腹腔镜下宫颈环扎术,观察术后妊娠情况。结果 16例患者手术过程均顺利,无一例中转开腹。有10例患者妊娠,其中8例孕足月剖宫产,1例孕31周剖宫产分娩,1例妊娠20周时因胎膜早破导致难免流产,开腹手术剪断环扎带后经阴道娩出胎儿。行剖宫产患者平均分娩孕周为37.9周,较术前平均流产孕周平均延长17.9周。另6例患者中5例现术后1～3个月,尚未计划妊娠,1例术后1+年,未避孕未孕。结论腹腔镜下宫颈环扎术安全有效,可明显延长妊娠时间,增加活产率,可作为宫颈机能不全的治疗方法之一。     

宫颈环扎术在早产治疗中的应用

目的评估治疗性宫颈环扎术及预防性宫颈环扎术的效果。方法选择2003年1月至2006年3月北京大学第三医院的34周前的早产临产及宫颈机能不全患者,早产临产患者采取紧急宫颈环扎术联合宫缩抑制剂或者单纯使用宫缩抑制剂治疗。宫颈机能不全患者采取预防性宫颈环扎术、紧急环扎术以及非环扎保守治疗。对治疗结局进行统计学分析。结果在早产临产组,紧急宫颈环扎联合宫缩抑制剂（硫酸镁）来治疗早产,平均保胎天数45.00 d,较单纯用宫缩抑制剂硫酸镁抑制宫缩的34例患者保胎天数[中位数为1（0.75-16）d]明显延长,34、37周后分娩率分别为66.7%（26/39）、30.8%（12/39）,明显增加。宫颈机能不全患者预防性环扎及治疗性环扎均较非环扎组保胎天数延长,增加32、34周后的分娩率（P〈0.05）,但治疗性环扎可降低早产率（P=0.02）。结论观察资料结果显示早产临产患者硫酸镁联合宫颈环扎治疗早产效果更佳,增加34周以上的分娩率,降低早产率;预防性环扎不能降低37周前早产率,但能增加32、34周后分娩率,延长保胎天数;治疗性环扎可降低37周前早产率。     

Positive vaginal culture at rescue cerclage predicts subsequent preterm delivery

Purpose: This retrospective case-control study is aimed to extract predictors of preterm delivery after rescue cerclage.

Materials and methods: We collected the data from all the pregnant women who underwent rescue cerclage before 26⁺⁰ gestational weeks at our facility between July 2006 and July 2016. These women were divided into “delivery at <34 weeks” group (n?=?12) and “delivery at ≥34 weeks” group (n?=?12). Multiple factors that had been detected at the time of cerclage were compared between these two groups.

Results: “Gestational weeks at cerclage ≥23” and “positive vaginal culture at cerclage” were significantly more prevalent in the “delivery at <34 weeks” group than in the “delivery at ≥34 weeks” group. “Prolapsed membranes at cerclage” tended to be more prevalent in the “delivery at <34 weeks” group than in the “delivery at ≥34 weeks” group. “Positive vaginal culture at cerclage” was the only independent risk factor associated with eventual preterm delivery before 34 gestational weeks.

Conclusions: Simple aerobic bacterial culture of the vaginal swab sampled at the time of cerclage could be used as a reliable test to predict subsequent preterm delivery before 34 gestational weeks.     

Effectiveness of cervical cerclage for a sonographically shortened cervix: a systematic review and meta-analysis

OBJECTIVE: The purpose of this study was to determine the effectiveness of cerclage for a shortened cervix on transvaginal ultrasound scanning in terms of the rates of preterm delivery and adverse neonatal and maternal outcomes. STUDY DESIGN: Pre-MEDLINE and MEDLINE, EMBASE, and the Cochrane Library were searched for human studies that compared cerclage placement to no cerclage on the basis of transvaginal ultrasound findings of a short cervix (< or =2.5 cm). Two authors independently determined eligibility and abstracted data. Meta-analyses were conducted when possible. RESULTS: Thirty-five studies were reviewed; 6 studies were eligible and were included in the analysis. There was no statistically significant effect of cerclage on the rates of preterm delivery (<37, <34, <32, and <28 weeks of gestation), preterm labor, neonatal mortality or morbidity, gestational age at delivery, or time to delivery. Birth weight was significantly higher with than without cerclage (P=.004). CONCLUSION: The available evidence does not support cerclage for a sonographically detected short cervix. A randomized controlled trial is needed to determine whether this intervention will reduce adverse neonatal outcomes.     

Preconception transabdominal cervicoisthmic cerclage

OBJECTIVE: The purpose of this study was to report pregnancy outcome and complication rates for women with recurrent late pregnancy loss who were treated with preconception transabdominal cervicoisthmic cerclage. STUDY DESIGN: This was a case note review of 19 women at high risk for second trimester loss and early preterm delivery who were treated with preconception transabdominal cervicoisthmic cerclage at Queen Charlotte's and Chelsea Hospital from 1994 to 2003. RESULTS: Preconception transabdominal cervicoisthmic cerclage was associated with a postoperative fetal survival rate of 100% for pregnancies that reached >12 weeks of gestation, compared with a preoperative fetal survival rate of 12%. There were no significant intraoperative, antenatal, intrapartum or neonatal complications. CONCLUSION: Within this case series, preconception transabdominal cervicoisthmic cerclage was a safe alternative to transabdominal cervicoisthmic cerclage that was performed in pregnancy with no risk to a fetus. It should be considered in appropriate cases in women seen for prepregnancy counseling.

Laparoscopic transabdominal isthmic cerclage in a case of cervical agenesis and a successful pregnancy with ICSI

The objective was to construct a laparoscopic transabdominal isthmic cerclage in a patient with cervical agenesis at Kadir Has University, Metropolitan Florence Nightingale Hospital. A 39-year-old woman diagnosed with primary infertility due to cervical agenesis was admitted to our hospital because of recurrent assisted reproductive technique (ART) failures. She underwent three operations for acute abdominal pain due to endometriosis and pyometra. There was a tiny fistula-like opening at the level of the isthmus, through which menstrual blood passed. Three intracytoplasmic sperm injection (ICSI) attempts with transmyometrial transfer had failed at three different IVF centres. We performed a laparoscopic transabdominal isthmic cerclage to prevent a miscarriage due to a clinical condition similar to cervical insufficiency and then an ICSI procedure was performed. We delivered a healthy baby weighing 3,200 g by Caesarean section. We left the cerclage in place for subsequent pregnancies. To the best of our knowledge, this is the first report of laparoscopic isthmic cerclage for the prevention of a clinical condition similar to cervical insufficiency in cervical agenesis that has resulted in a term pregnancy after ICSI.     

Cervical surveillance as an alternative to elective cervical cerclage for pregnancy management of suspected cervical incompetence

OBJECTIVE: The aim of the present study was to compare the outcome of pregnancies among patients with suspected cervical incompetence treated either by elective cervical cerclage or an alternative management program involving cervical surveillance. DESIGN, SETTING AND METHODS: A prospective cohort study was performed in two groups of patients at risk of cervical incompetence with singleton gestations attending the Royal Women's Hospital, Melbourne, Australia, from 1996 to 2000. The first group was managed by their obstetric carers with an elective cerclage, while the second group was managed conservatively as part of a cervical surveillance program offered to patients attending the Department of Perinatal Medicine for pregnancy care. This program consists of weekly visits from 16 weeks' gestation and involves alternating transvaginal ultrasound assessment of cervical morphometry with cervico-vaginal bacteriology and fetal fibronectin swabs. Empiric insertion of a cerclage is undertaken when there is evidence of significant cervical shortening (cervical canal <2.5 cm in length at 相似文献   

孕前经阴道子宫颈峡部环扎术治疗宫颈机能不全

宫颈环扎术是目前治疗宫颈机能不全最有效的方法。术式包括Shirodkar和McDonald提出的经阴道宫颈环扎术以及Benson 和Durfee提出的经腹宫颈环扎术。前者环扎位置偏低,效果欠理想,后者手术效果肯定,但需两次进腹进行环扎和拆线,增加了手术创伤和风险。笔者对上述两种宫颈环扎术进行综合,于孕前经阴道在宫颈峡部水平行环扎术123例,发现该术式操作方便,效果理想,拆除方便,是一种值得与各位同道分享的宫颈环扎术式。

Transvaginal cervico-isthmic cerclage: a simple approach

In this article, we describe a relatively simple surgical option that we believe is indicated for use in cases of cervical incompetence. We discuss the advantages of this procedure to the surgeon and patient, and give details of 59 patients who have undergone this procedure one or more times over a 13-year period. A short review of the history of treatment of cervical incompetence and of recent trends for its management is also presented.     

Comparison of two successive policies of cervical cerclage for the prevention of pre-term birth.

The percentage of women receiving cervical cerclage increased from 5% to 18% between two periods at Haguenau maternity hospital, according to a new policy for the prevention of pre-term birth. A parallel reduction of premature deliveries by about a half was observed in the relevant group of women. This suggests that cerclage might be employed on another basis than is currently the case, and that a randomized trial is urgently needed to define its indications more precisely.
