[Intrahepatic cholestasis of pregnancy: French College of Obstetricians and Gynecologists guidelines for clinical practice]. / La cholestase gravidique : recommandations pour la pratique clinique du Collège national des gynécologues obstétriciens français.

OBJECTIVE: To identify strategies for reducing neonatal and maternal morbidity associated with intrahepatic cholestasis pregnancy (ICP). MATERIAL AND METHODS: The quality of evidence of the literature was assessed following the GRADE methodology with questions formulated in the PICO format (Patients, Intervention, Comparison, Outcome) and outcomes defined a priori and classified according to their importance. An extensive bibliographic search was performed on PubMed, Cochrane, EMBASE and Google Scholar databases. The quality of the evidence was assessed (high, moderate, low, very low) and a (i) strong or (ii) weak recommendations or (iii) no recommendation were formulated. The recommendations were reviewed in two rounds with external reviewers (Delphi survey) to select the consensus recommendations. RESULTS: Of the 14 questions (from 12 PICO questions and one definition question outside the PICO format), there was agreement between the working group and the external reviewers on 14 (100%). The level of evidence of the literature was insufficient to provide a recommendation on two questions. ICP is defined by the occurrence of suggestive pruritus (palmoplantar, nocturnal) associated with a total bile acid level>10µmol/L or an alanine transaminase level above 2N after ruling out differential diagnoses. In the absence of suggestive symptoms of a differential diagnosis, it is recommended not to carry out additional biological or ultrasound tests. In women with CIP, ursodeoxycholic acid is recommended to reduce the intensity of maternal pruritus (Strong recommendation. Quality of the evidence moderate) and to decrease the level of total bile acids and alanine transaminases. (Strong recommendation. Quality of the evidence moderate). S-adenosyl-methionine, dexamethasone, guar gum or activated charcoal should not be used to reduce the intensity of maternal pruritus (Strong recommendation. Quality of evidence low), and there is insufficient data to recommend the use of antihistamines (No recommendation. Quality of evidence low). Rifampicin (Weak recommendation. Very low quality of evidence) or plasma exchange (Strong recommendation. Very low quality of evidence) should not be used to reduce maternal pruritus and perinatal morbidity. Serum monitoring of bile acids is recommended to reduce perinatal morbidity and mortality (stillbirth, prematurity) (Low recommendation. Quality of the evidence low). The level of evidence is insufficient to determine whether fetal heart rate or fetal ultrasound monitoring are useful to reduce perinatal morbidity (No recommendation). Birth is recommended when bile acid level is above 99µmol/L from 36 weeks gestation to reduce perinatal morbidity, in particular stillbirth. When bile acid level is above 99µmol/L is below 100µmol/L, women should be informed that induction of labor could be considered 37 and 39 weeks gestation to reduce perinatal morbidity. (Strong recommendation. Quality of evidence low). In postpartum, total bile acids and alanine transaminases level should be checked and normalized before prescribing estrogen-progestin contraception, ideally with a low estrogen dose (risk of recurrence of pruritus and cytolysis) (Low recommendation. Quality of evidence very low). CONCLUSION: Although the quality of evidence regarding ICP gestational cholestasis remains low, there is a strong consensus in France, as shown by our Delphi study, on how to manage women with ICP. The reference first-line treatment is ursodeoxycholic acid.

[CNGOF clinical practice guidelines: Evaluation one year after revision of the methodology]. / Recommandations pour la pratique clinique du CNGOF : évaluation un an après révision de la méthodologie.

OBJECTIVES: To evaluate the revision of methodology of the clinical practice guidelines (CPG) of the French National College of Gynecologists and Obstetricians (CNGOF). METHOD: Three CPGs were organized in 2020 on the topics of severe preeclampsia, menorrhagia, and prophylactic surgery according to AGREE II (Apraisal of Guidelines for Research & Evaluation). Questions were presented in PICO (Population, Intervention, Comparison, Outcome) format and the grading of scientific evidence was based on the GRADE (Grading of Recommendation Assessment, Development and Evaluation) method. RESULTS: All three CPGs groups adhered to this new methodology. However, the presentation of the arguments, the formulation of the recommendations and the development of the GRADE tables were heterogeneous from one group to another. A homogenization of the presentation is proposed, as well as a guide to the critical analysis of the literature to help the experts to rate the evidence. CONCLUSION: Adherence to these quality criteria should make it easier to apply the recommendations at the national level and improve international recognition of the work done by the CNGOF.

[Antenatal ultrasound prediction of esophageal atresia type]. / Prédiction échographique anténatale du type d'atrésie de l'œsophage.

BACKGROUND: Esophageal atresia (EA) is a rare congenital malformation of the upper aerodigestive tract, which can be diagnosed antenatally in 50-65% of cases. Postnatal management differs according to the type of EA. No studies have evaluated the correlation of antenatal ultrasound findings with the type of EA. OBJECTIVE: The main objective is to study the association between antenatal ultrasound signs and the type of EA. The secondary objective is to study the association between postnatal morbidity and the type of EA. METHOD: We conducted a single-center retrospective study between May 2010 and August 2019. Fetuses with suspected prenatal EA and postnatal diagnosis confirmation were included. Postnatal confirmation of EA was performed during surgery for live births and by fetopathological examination for termination of pregnancy. Prenatal signs and postnatal morbidity were compared according to the type of EA. RESULTS: We included 15 cases of postnatally confirmed EA, including 9 type 1EA, 5 type 3EA and 1 type 4EA (11 live births and 4 terminations of pregnancy). The gestational age at diagnosis was earlier in type 1EA: 22+0 [6-21,21-24] versus 30+0 [28+0-32+0] (P=0.03). Compared to type 3EA, type 1EA had a higher incidence of non-visible stomach bubble (89% versus 40%, P=0.09) and upper esophageal cul-de-sac dilatation (56% versus 0%, P=0.09). Neonatal morbidity in type 1EA was more severe with a longer hospital stay in neonatal intensive care. CONCLUSION: The antenatal ultrasound signs seem to be more pronounced in case of type 1EA. Type 1EA is associated with severe morbidity compared to Type 3EA. Improving prenatal diagnosis of EA and its type allows a more accurate prognostic evaluation.

[Prevention of spontaneous preterm birth (excluding preterm premature rupture of membranes): Guidelines for clinical practice - Text of the Guidelines (short text)]. / Recommandations pour la pratique clinique : prévention de la prématurité spontanée et de ses conséquences (hors rupture des membranes) ­ Texte des recommandations (texte court).

OBJECTIVES: To determine the measures to prevent spontaneous preterm birth (excluding preterm premature rupture of membranes)and its consequences. MATERIALS AND METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: In France, premature birth concerns 60,000 neonates every year (7.4 %), half of them are delivered after spontaneous onset of labor. Among preventable risk factors of spontaneous prematurity, only cessation of smoking is associated to a decrease of prematurity (level of evidence [LE] 1). This is therefore recommended (grade A). Routine screening and treatment of vaginal bacteriosis in general population is not recommended (grade A). Asymptomatic women with single pregnancy without history of preterm delivery and a short cervix between 16 and 24 weeks is the only population in which vaginal progesterone is recommended (grade B). A history-indicated cerclage is not recommended in case of only past history of conisation (grade C), uterine malformation (Professional consensus), isolated history of pretem delivery (grade B) or twin pregnancies in primary (grade B) or secondary (grade C) prevention of preterm birth. A history-indicated cerclage is recommended for single pregnancy with a history of at least 3 late miscarriages or preterm deliveries (grade A).). In case of past history of a single pregnancy delivery before 34 weeks gestation (WG), ultrasound cervical length screening is recommended between 16 and 22 WG in order to propose a cerclage in case of length<25mm before 24 WG (grade C). Cervical pessary is not recommended for the prevention of preterm birth in a general population of asymptomatic women with a twin pregnancy (grade A) and in populations of asymptomatic women with a short cervix (Professional consensus). Although the implementation of a universal transvaginal cervical length screening at 18-24 weeks of gestation in women with a singleton gestation and no history of preterm birth can be considered by individual practitioners, this screening cannot be universally recommended. In case of preterm labor, (i) it is not possible to recommend one of the methods over another (ultrasound of the cervical length, vaginal examination, fetal fibronectin) to predict preterm birth (grade B); (ii) routine antibiotic therapy is not recommended (grade A); (iii) prolonged hospitalization (grade B) and bed rest (grade C) is not recommended. Compared with placebo, tocolytics are not associated with a reduction in neonatal mortality or morbidity (LE2) and maternal severe adverse effects may occur with all tocolytics (LE4). Atosiban and nifedipine (grade B), contrary to betamimetics (grade C), can be used for tocolysis in spontaneous preterm labour without preterm premature rupture of membranes. Maintenance tocolysis is not recomended (grade B). Antenatal corticosteroid administration is recommended to every woman at risk of preterm delivery before 34 weeks of gestation (grade A). After 34 weeks, evidences are not consistent enough to recommend systematic antenatal corticosteroid treatment (grade B), however, a course might be indicated in the clinical situations associated with the higher risk of severe respiratory distress syndrome, mainly in case of planned cesarean delivery (grade C). Repeated courses of antenatal corticosteroids are not recommended (grade A). Rescue courses are not recommended (Professional consensus). Magnesium sulfate administration is recommended to women at high risk of imminent preterm birth before 32WG (grade A). Cesarean is not recommended in case of vertex presentation (Professional consensus). Both planned vaginal or elective cesarean delivery is possible in case of breech presentation (Professional consensus). A delayed cord clamping may be considered if the neonatal or maternal state so permits (Professional consensus). CONCLUSION: Except for antenatal corticosteroid and magnesium sulfate administration, diagnostic tools or prenatal pharmacological treatments implemented since 30 years to prevent preterm birth and its consequences have not matched expectations of caregivers and families.

[Post-partum: Guidelines for clinical practice--Short text]. / Post-partum: recommandations pour la pratique Clinique--Texte court.

OBJECTIVE: To determine the post-partum management of women and their newborn whatever the mode of delivery. MATERIAL AND METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Because breastfeeding is associated with a decrease in neonatal morbidity (lower frequency of cardiovascular diseases, infectious, atopic or infantile obesity) (EL2) and an improvement in the cognitive development of children (EL2), exclusive and extended breastfeeding is recommended (grade B) between 4 to 6 months (Professional consensus). In order to increase the rate of breastfeeding initiation and its duration, it is recommended that health professionals work closely with mothers in their project (grade A) and to promote breastfeeding on demand (grade B). There is no scientific evidence to recommend non-pharmacological measures of inhibition of lactation (Professional consensus). Pharmacological treatments for inhibition of lactation should not be given routinely to women who do not wish to breastfeed (Professional consensus). Because of potentially serious adverse effects, bromocriptin is contraindicated in inhibiting lactation (Professional consensus). For women aware of the risks of pharmacological treatment of inhibition of lactation, lisuride and cabergolin are the preferred drugs (Professional consensus). Whatever the mode of delivery, numeration blood count is not systematically recommended in a general population (Professional consensus). Anemia must be sought only in women with bleeding or symptoms of anemia (Professional consensus). The only treatment of post-dural puncture headache is the blood patch (EL2), it must not be carried out before 48 h (Professional consensus). Women vaccination status and their family is to be assessed in the early post-partum (Professional consensus). Immediate postoperative monitoring after caesarean delivery should be performed in the recovery room, but in exceptional circumstances, it may be performed in the delivery unit provided safety rules are maintained and regulatory authorities are informed (Professional consensus). An analgesic multimodal protocol developed by the medical team should be available and oral way should be favored (Professional consensus) (grade B). For every cesarean delivery, thromboprophylaxis with elastic stockings applied on the morning of the surgery and kept for at least 7 postoperative days is recommended (Professional consensus) with or without the addition of LMWH according to the presence or not of additional risk factors, and depending on the risk factor (major, minor). Early postoperative rehabilitation is encouraged (Professional consensus). Postpartum visit should be planned 6 to 8 weeks after delivery and can be performed by an obstetrician, a gynecologist, a general practitioner or a midwife, after normal pregnancy and delivery (Professional consensus). Starting effective contraception later 21 days after delivery in women who do not want closely spaced pregnancy is recommended (grade B), and to prescribe it at the maternity (Professional consensus). According to the postpartum risk of venous thromboembolism, the combined hormonal contraceptive use before six postpartum weeks is not recommended (grade B). Rehabilitation in asymptomatic women in order to prevent urinary or anal incontinence in medium or long-term is not recommended (Expert consensus). Pelvic-floor rehabilitation using pelvic-floor muscle contraction exercises is recommended to treat persistent urinary incontinence at 3 months postpartum (grade A), regardless of the type of incontinence. Postpartum pelvic-floor rehabilitation is recommended to treat anal incontinence (grade C). Postpartum pelvic-floor rehabilitation is not recommended to treat or prevent prolapse (grade C) or dyspareunia (grade C). The optimal time for maternity discharge for low risk newborn depends more on the organisation of the post-discharge follow up (Professional consensus). The months following the birth are a transitional period, and psychological alterations concern all parents (EL2). It is more difficult in case of psychosocial risk factors (EL2). In situations of proven psychological difficulties, the impact on the psycho-emotional development of children can be important (EL3). Among these difficulties, postpartum depression is the most common situation. However, the risk is generally higher in the perinatal period for all mental disorders (EL3). CONCLUSION: Postpartum is, for clinicians, a unique and privileged opportunity to address the physical, psychological, social and somatic health of their patients.

[Progesterone and prevention of preterm birth]. / Progestérone et prévention de l'accouchement prématuré.

The literature confirms the interest of progesterone for prevention of preterm delivery in specific indications for patients carrying a singleton pregnancy. In contrast, randomized trials have shown no benefit using progesterone in the prevention of prematurity in twins and even an adverse effect.

[Fetal therapy and fetoscopy: A reality in clinical practice in 2015]. / Thérapie fœtale et fœtoscopie : une réalité clinique en 2015.

Both the improvement of pathophysiological knowledge of major fetal anomalies and the development of therapeutic tools have allowed in some specific cases in utero therapy by foetoscopy. We discuss the state of art and recent advances for four major anomalies: twin-to-twin transfusion syndrome, congenital diaphragmatic hernia, myelomeningocele and lower urinary tract obstruction. Fetoscopic laser surgery for twin-to-twin transfusion syndrome has become the gold standard for treatment of TTS. In terms of fetal surgery, severe congenital diaphragmatic hernia and myelomeningocele are the two main indications, even if open fetal surgery is still the gold standard for management of myelomeningocele. New techniques using fetal cystoscopy are currently under development. Although the maternal morbidity associated with foetoscopy is low, preterm rupture of membranes and preterm delivery remain an important problem. Long-term evaluation of those neonates remains mandatory.

Stomach position in prediction of survival in left-sided congenital diaphragmatic hernia with or without fetoscopic endoluminal tracheal occlusion.

OBJECTIVE: To investigate the value of fetal stomach position in predicting postnatal outcome in left-sided congenital diaphragmatic hernia (CDH) with and without fetoscopic endoluminal tracheal occlusion (FETO). METHODS: This was a retrospective review of CDH cases that were expectantly managed or treated with FETO, assessed from May 2008 to October 2013, in which we graded, on a scale of 1-4, stomach position on the four-chamber view of the heart with respect to thoracic structures. Logistic regression analysis was used to investigate the effect of management center (Paris, Brussels, Barcelona, Milan), stomach grading, observed-to-expected lung area-to-head circumference ratio (O/E-LHR), gestational age at delivery, birth weight in expectantly managed CDH, gestational ages at FETO and at removal and period of tracheal occlusion, on postnatal survival in CDH cases treated with FETO. RESULTS: We identified 67 expectantly managed CDH cases and 47 CDH cases that were treated with FETO. In expectantly managed CDH, stomach position and O/E-LHR predicted postnatal survival independently. In CDH treated with FETO, stomach position and gestational age at delivery predicted postnatal survival independently. CONCLUSION: In left-sided CDH with or without FETO, stomach position is predictive of postnatal survival.

[Progesterone and preterm delivery: back to the future?]. / Progestérone et prévention de l'accouchement prématuré: retour vers le future?

Progesterone was widely used in France during the 1980s and 1990s to prevent preterm birth until some published cases of cholestasis suddenly stopped its prescription. Since then, multiple randomized controlled trials have emerged and demonstrated the efficiency of the treatment but also its safety at low doses. In order to clarify its indications, we performed a current literature review. We analyzed literature data according to different categories of risk and different routes of administration. Results confirm that progesterone is an efficient treatment to prevent preterm birth in singleton gestation with short cervical length, and in singleton gestation with prior preterm birth with or without short cervical length. Apart from these indications, progesterone, especially 17-alpha-hydroxyprogesterone (17OHP), should not be used outside research protocols.

[Fetomaternal hemorrhage caused by intraplacental choriocarcinoma]. / Hémorragie foetomaternelle sur choriocarcinome placentaire.

A male infant was born at 41 weeks' gestation to a 34-year-old primiparous woman after an uneventful pregnancy. Physical examination showed extreme paleness. Fetal hemoglobin was 7.6g/dl and Kleihauher exam revealed fetomaternal hemorrhage. Pathology revealed in situ intraplacental choriocarcinoma. Serum human chorionic gonadotrophin level was undetectable 1 month after the delivery both in woman and in newborn. We suggest that a pathological examination of the placenta should be performed in any case of fetomaternal hemorrhage in order to avoid misdiagnosis of intraplacental choriocarcinoma.

Using Z-scores to compare biometry data obtained during prenatal ultrasound screening by midwives and physicians.

OBJECTIVE: To compare retrospectively the distribution of foetal biometry data as measured by midwives and physicians during second and third trimester screening of an unselected population of pregnant women. METHODS: Standard measurements of biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) were performed by four midwives and ten physicians at 20 to 24 weeks of gestation and at 30 to 34 weeks of gestation as part of routine ultrasound examinations over a 26-month period (Jan. 2005-Mar. 2007). All measurements were converted into Z-scores using different prediction equations. The reference chart best fitting our practice was determined for each fetal parameter (French College of Sonographers for BPD, Chitty et al. for HC and FL, Snidjers and Nicolaides for AC). The means and SDs of the Z-score distributions for data collected by midwives and physicians were compared using Student's t-test for means and the Fisher-Snedecor test for SDs. RESULTS: We retrieved 1566 and 1631 measurements made by midwives and physicians respectively between 20 and 24 weeks of gestation, and 1710 and 1578 measurements made by midwives and physicians respectively between 30 and 34 weeks of gestation. Mean values recorded by midwives were significantly closer to 0 (p < 0.05) for many foetal parameters. SD values were also significantly lower and were below 1. CONCLUSION: In this study, midwives have a greater tendency than physicians to normalize biometry data. Such normalization may hamper the sensitivity of routine ultrasound screening for abnormal foetal growth.

A 2-year study on cytomegalovirus infection during pregnancy in a French hospital.

OBJECTIVES: To evaluate the proportion of pregnant women agreeing to cytomegalovirus (CMV) serologic screening. To collect data on CMV infection during pregnancy. DESIGN: Prospective study. SETTING: During two years, all pregnant women were informed on CMV infection. If the patient agreed, serological testing was performed around 12 weeks of gestation (WG) and, if negative, redone around 36 WG. POPULATION: Four thousand two hundred and eighty-seven pregnant women followed from 12 weeks to delivery. METHODS: If the first CMV serologic test was negative, detailed hygiene information was given to the parents. Diagnosis of primary infection was based on the detection of CMV-G, CMV-M and low CMV-G avidity index. When maternal infection was confirmed, diagnosis of CMV congenital infection was done in the newborns by urine culture within the three days following birth. Crude infection-rate data consisted of the number of CMV infection cases and person-time units for both exposed to hygiene CMV information (12 to 36 WG) and unexposed pregnant women (first 12 WG). MAIN OUTCOME MEASURES: Rate of CMV seropositive and seronegative women. Rate of women agreeing for screening. Rate of primary infection. Rate of seroconversion. Number of CMV-infected newborns. RESULTS: Among the 4287 women followed, 3792 were either seronegative or with an unknown immune status. 96.7% out of them agreed for screening. 53.2% were initially CMV-specific IgG negative. Primary infection was detected in nine women between 0 and 12 WG (0.46%) and seroconversion was diagnosed in five women between 12 and 36 WG (0.26%) (mid P = 0.02, 95% CI [1.07-13.6]). CONCLUSIONS: If clear information on CMV infection during pregnancy is given, patients frequently agree to screening. The rate of seroconversion after information, observed in this study, is low after counselling.

Imaging of the fetal bony pelvis by computed tomography in a case of bladder exstrophy.

We describe the findings on computed tomography (CT) in a prenatally diagnosed case of bladder exstrophy, and compare them with the findings on two- and three-dimensional sonography. The CT data of the affected fetus were compared with the CT findings of 14 fetuses with normal bony pelvises. The CT images showed differences in the structure of the bony pelvis in the case of bladder exstrophy, with a wide gap between the iliopubic and ischiopubic rami and a widening of the iliac bones. CT scanning was useful in confirming the sonographic diagnosis of bladder exstrophy, and it may also be helpful for planning early surgery following delivery.

[Management of antenatal fetal abdominal tumors. Clues for the diagnosis of a congenital mesoblastic nephroma]. / Conduite à tenir obstétricopédiatrique devant la découverte anténatale d'une masse hyperéchogène rétropéritonéale. Arguments en faveur d'un néphrome mésoblastique congénital.

The prenatal diagnosis of abdominal mass poses the problem of its origin. Renal tumors are rarer than neuroblastoma but they are most often congenital mesoblastic nephroma. The congenital mesoblastic nephroma has a good forecast in spite of a sonographic impressive aspect. MRI can help to locate tumor but cannot tell difference between the different kinds of renal tumor. Prenatal forecast is especially linked with hydramnios and hydrops fetalis. Histolological study of the tumor is important for the prognosis. Two morphological subtypes are currently distinguished: the classic type with a good forecast and the atypical or cellular type. Distant metastases have been related only to the cellular form but especially in infants aged more than 3 months and never in the newborns. The diagnosis of the tumor does not change the mode of delivery except in case of an important volume. Complications are searched during the first days of life: hypertension, hypercalcemia, vomiting, hyperreninemia. Radical nephrectomy is performed after the end of the first week. In case of a classic form, the healing is always obtained. In case of cellular form, distant metastases are searched. In any rate, the follow-up is recommended until the end of the growth.

Prenatal diagnosis of a patent urachus cyst with the use of 2D, 3D, 4D ultrasound and fetal magnetic resonance imaging.

Patent urachus cyst is a rare umbilical anomaly, which is poorly detected prenatally and frequently confounded with pseudo bladder exstrophy or omphalocele. A 27-year-old woman was referred to our prenatal diagnosis centre at 18 weeks of gestation after diagnosis of a megabladder and 2 umbilical cord cysts. Subsequent 2D, 3D and 4D ultrasound examinations and fetal magnetic resonance imaging (MRI) revealed a typical umbilical cyst and an extra-abdominal cyst, communicating with the vertex of the fetal bladder through a small channel that increased in size when the fetus voided urine. Termination of pregnancy occured at 31 weeks because of associated cerebral septal agenesis, and autopsy confirmed the prenatal diagnosis of urachus cyst. Few cases of urachus cyst diagnosed prenatally are reported in literature, but none were associated with other extra-abdominal disorders and none used 3D, 4D and fetal MRI. Our case illustrated the efficiency in prenatal diagnosis of 3D and 4D ultrasound examinations. This could help pediatrician surgeons to explain to a couple about neonatal surgical repair and plastic reconstruction in the prenatal period.

[Cervical cerclage in 2008]. / Le cerclage du col utérin en 2008.

Cervical cerclage is a common surgical technique that has been used for more than 50 years to prevent preterm deliveries and in the management of a threatened second trimester loss. However, it remains one of the most controversial interventions in obstetrics and this is probably due to difficulties in diagnosing cervical insufficiency, which is based on a history of recurrent second trimester loss or early preterm delivery following painless cervical dilatation in the absence of contractions or bleeding. This article reviews in 2008 the current literature regarding the efficacy of elective cerclage, ultrasound-indicated cerclage, emergency cerclage, and cervico-isthmic cerclage for singletons and multiple pregnancies.

Fetal magnetic resonance imaging in the antenatal diagnosis and management of hydrocolpos.

Hydrocolpos should be considered systematically when an abdominopelvic cystic mass is diagnosed in a female fetus. Because the prognosis and neonatal management of isolated hydrocolpos with spontaneous resolution differs greatly from that of hydrocolpos associated with a cloacal malformation, it is important to ascertain prenatally whether there are associated anomalies. We report the prenatal characteristics of three fetuses with hydrocolpos; in two cases there was spontaneous resolution and one infant was born with digestive tract atresia. The principal ultrasound findings were an oblong anechoic pelvic mass with or without a sagittal septum, located behind a normal bladder. On magnetic resonance imaging (MRI), the cervical imprint on the vagina confirmed the diagnosis of hydrocolpos and helped to diagnose cloacal malformation by demonstrating the absence of meconium beside the bladder on T1 sequences. Our cases show that MRI is useful for differentiating isolated hydrocolpos from hydrocolpos associated with cloacal malformation.

[Transvaginal cervico-isthmic cerclage using polypropylene tape: surgical procedure and pregnancy outcome: Fernandez's procedure]. / Technique de cerclage cervico-isthmique par voie vaginale avec bandelette de polypropylène: technique de Fernandez.

OBJECTIVE: To assess the efficacy of performing transvaginal cervico-isthmic cerclage using synthetic tape in prevention of preterm labor in high-risk women. PATIENTS AND METHODS: A retrospective analysis of 24 transvaginal cerclages using polypropylene tape performed in women presenting with high risk of preterm delivery: prior histories of pregnancy losses in the second trimester, prior failure of Mac Donald's cerclage and/or absent portio vaginalis of the cervix. Cerclage was performed between 12 and 16 weeks of gestation. A polypropylene tape was placed at the cervicoisthmic junction by vaginal route. RESULTS: The median age of the patients in this series was 32.1 years (range 22-39 years). No intra-operative complication occurred. The median operating time was 34.9 minutes (+/-5.1) (range 30-45 min). Cesarean delivery was systematically performed in all patients since the cerclage was considered to be definitive. Mean gestational age and birth weight at delivery were respectively 37.1 weeks (+/-1.8) and 2850 g (+/-745). Preterm birth rate was 19% (4/21). Birth at less than 32 weeks occurred in only one patient (4%). In one case, the tape has been removed later because symptomatic vaginal erosion was noted. One neonatal death occurred following amniotic fluid infection at 34 weeks. At the present time, 3 women are at 22, 26 and 26 weeks of gestation with no preterm labor. CONCLUSION: Transvaginal cerclage using polypropylene tape may be considered as an effective and minimally invasive alternative to transabdominal cervico-isthmic cerclage in women presenting with high risk of preterm delivery.
