[Para-arortic lymhadenectomy and pelvic gynecological cancers: Extraperitoneal or transperitoneal laparoscopy?]

INTRODUCTION

Para-aortic lymphadenectomy plays a fundamental role in the surgical management of pelvic gynecological cancers. Two laparoscopic approaches exist: the transperitoneal (TP) and the extraperitoneal (EP). The aim of this study was to compare these 2 approaches in terms of surgical outcomes, specially the number of removed lymph nodes according to the surgical technique, and morbidity.

MATERIALS AND METHOD

A single-center retrospective study was carried out at the Lariboisiere University Hospital between January 2011 and March 2020 including all patients who underwent para-aortic lymphadenectomy for the management of a pelvic gynecological cancer (cervix, endometrium, ovary). Univariate and multivariate analysis (logistic regression) were performed to compare the TP and the EP groups.

RESULTS

143 patients were included: 74 in the TP group and 69 in the RP group. The total duration of surgery was 220.8minutes in the TP group and 166.4minutes in the EP group (P<0.001 in multivariate analysis). No significant difference between groups were found in the average total number of lymph nodes removed but there was a statistically significant difference in the average latero-aortic number of lymph nodes removed: 8.5 lymph nodes in the TP group and 11.3 lymph nodes in the group RP (P<0.001 in multivariate analysis). There was no difference between groups in peri and postoperative morbidity.

CONCLUSION

EP para-aortic lymphadenectomy reduces duration of surgery and increases the average latero-aortic number of lymph nodes removed with same morbidity compared to TP para-aortic lymphadenectomy, this confirming its preferred indication in endometrial and in cervical cancers.

Low pressure gynecological laparoscopy (7mmHg) with AirSeal® System versus a standard insufflation (15mmHg): A pilot study in 60 patients

OBJECTIVES

To evaluate feasibility of performing benign gynecologic pathology low pressure (7mmHg) laparoscopy (LPL) with AirSeal^® system and to study benefits in terms of postoperative pain, when compared to a standard insufflation group (15mmHg).

MATERIALS AND METHODS

In this prospective randomized pilot study, 60 patients had laparoscopy for gynecologic benign pathology: 30 with 7mmHg and AirSeal system, and 30 with 15mmHg standard insufflator. The primary endpoint was incidence of shoulder pain. A postoperative questionnaire was completed by each patient to assess shoulder pain (Numeric Rating Scale [NRS], from 0 to 10) at H4, H8, H24, and consumption of morphinics was notified. During each procedure, anesthesia parameters were collected (peak airway pressure, systolic blood pressure, end tidal CO₂).

RESULTS

Laparoscopy was performed on 30 patients in AirSeal^®-LP group without need to increase pressure above 7mmHg, and no complication was reported. Incidence of shoulder pain was significantly lower in the AirSeal^®-LP group (23.3% vs. 73.3%, P<0.001). NRS shoulder pain was significantly lower in AirSeal^® LP group at hour 4, 8 and 24. Maximal values of ETCO₂, systolic blood pressure, and peak airway pressure were significantly lower in AirSeal^®-LP group.

CONCLUSION

LP (7mmHg) laparoscopy with AirSeal^® platform allows laparoscopic surgery with less postoperative shoulder pain. These results could facilitate the development of ambulatory laparoscopy.

[Prenatal diagnosis of cleft lip with or without cleft palate: retrospective study and review]

OBJECTIVES

To evaluate the management of prenatally diagnosed cleft lip with or without cleft palate and the immediate postnatal outcome.

MATERIAL AND METHODS

Retrospective study of all cases of cleft lip with or without cleft palate referred to our fetal medicine unit, between January 2005 and January 2011. The anatomical type of cleft, associated malformations, and the postnatal outcome were reviewed.

RESULTS

Forty-three cases of fetal cleft lip with or without cleft palate were reviewed. The mean gestational age at diagnosis was 24 weeks ± 4. The postnatal distribution of clefts was: 30 cleft lip and palate (70%) and 13 cleft lip (30%). The prenatal diagnosis of the cleft type was exact in 27 cases (62.8%). Nine cases had associated anomalies (21%), detected prenatally in three cases (37.5%). There was no karyotypical abnormality. Six pregnancies were terminated (14%). The immediate postnatal outcome was comparable with unselected newborns.

CONCLUSION

The prenatal diagnosis of cleft lip with or without cleft palate is correct, with two thirds of exact diagnoses. Large clefts palate are the best detected. Associated malformations cannot always be diagnosed by prenatal ultrasound, but have to be searched for because they modify the fetal outcome.

[Cervical pregnancy: a rare case of reimplantation after abortion. A case report]

Cervical pregnancy is a rare form of ectopic pregnancy defined by the implantation of the blastocyst in the cervical canal. Most of the cervical pregnancies have been reported in patients with a history of vacuum curettage or caesarean section. The authors report a case of cervical pregnancy occurred after a failure of medical abortion. A literature review discusses the possibility of a cervical secondary implantation and describes the management of such pregnancies.

[Postoperative abdominal adhesions and their prevention in gynaecological surgery: II. How can they be prevented?]

This paper is the second of a two-part publication. The initial paper provided a comprehensive overview of the evidence on adhesions to allow gynaecological surgeons to be best informed on adhesions, their development, impact on patients, health systems and surgical outcomes. There is rising evidence that surgeons can take important steps to reduce the burden of adhesions. In this second paper, we review the various strategies to reduce the impact of adhesions, improve surgical outcomes and provide some practical proposals for action on adhesions. As well as improvements in surgical technique, developments in adhesion-reduction strategies and new agents offer a realistic possibility of reducing adhesion formation and improving outcomes for patients. They should be considered for use particularly in high-risk surgery and in patients with adhesiogenic conditions. Further research into new strategies to prevent adhesions more effectively through an improved surgical environment, new and combination devices and pharmacological agents should be encouraged. Formal recommendations would ensure better prioritisation of adhesion-reduction within the French health system. Patients should also be better informed of the risks of adhesions.

[Giant retroperitoneal hematoma in the peripartum of a normal delivery, "expectative attitude"]

We describe a case involving spontaneous retroperitoneal hematoma complicating a normal delivery in a context of a Disseminated Intravascular Coagulation (DIVC) at the end of the pregnancy. Given the defaced symptomatology, an abdomino-pelvic scanner and an examination with a general anaesthesia made it possible to diagnose and to monitor the hematoma in intensive care. The correction of the hemostasis troubles and of the anemia, without another invasive intervention, allowed a return to home at the eighth day. The pathophysiological mechanisms underlying development and practicable treatments of this post-partum hematoma are discussed.

[First trimester fetal cardiac scanning for fetuses at higher risk for congenital heart disease]

OBJECTIVE

To describe the preliminary results of fetal cardiac scanning in the first trimester of pregnancy for fetuses at higher risk for congenital heart defect (CHD).

PATIENTS AND METHODS

Echocardiographic examination was performed at 12 to 14+6 in 67 patients at higher risk for fetal CHD. The indications for referral were: increased nuchal translucency more or equal to 99(e) centile (56 cases), risk of recurrence for CHD (eight cases), embryonic toxic exposure (eight cases), maternal disease (four cases).

RESULTS

Complete examination of the fetal heart was possible in 54/55 cases. Fetal cardiac examination was normal in 58 cases (87 %). Six cases of severe CHD were diagnosed: hypoplastic left heart syndrome, pulmonary atresia with intact septum, complex univentricular CHD leading to termination of pregnancy, conotroncal Fallot like abnormality, and transposition of great arteries. Post-mortem examination was performed in three cases and confirmed the cardiac anomalies.

DISCUSSION AND CONCLUSION

Our preliminary results confirmed that fetal heart scanning is feasible at the end of the first trimester of pregnancy. Severe CHD are amenable to prenatal diagnosis in the first trimester in the population at higher risk for CHD.

[Bladder endometriosis and barrenness: diagnostic and treatment strategy]

Deep infiltrating endometriosis is a well-known female disease responsible for chronic pelvic pain, urinary dysfunction, infertility, and altered quality of life. Endometriosis and infertility are complex entities and the optimal choice of management of both of them remains obscure. Mechanism of development of the disease has to be understood to optimize patients care. The link between barrenness and endometriosis is well known, but there is no direct link between bladder lesion and infertility. Bladder endometriosis is a deeply infiltrating endometriosis lesion. Its management is first diagnostic and then remedial. In case of ineffectiveness of medical strategy, surgical treatment is indicated. However, for patient suffering from symptomatic isolated bladder endometriosis, surgical management can be offered in first intention. Isolated bladder injuries due to endometriosis are mostly treated by conservative laparoscopic surgery, after a complete evaluation of endometriosis disease and barrenness by clinical exam and imaging techniques.

[Contribution of three dimensional imaging techniques in the visualization of the fetal uterus]

The prenatal diagnosis of ambiguous genitalia requires a complete examination of the fetal anatomy to rule out any other congenital defects and the analysis of the fetal genotype. In addition any additional information on the anatomy of the internal genitalia, i.e. the presence or absence of fetal uterus, may be relevant to the prenatal evaluation of female pseudo-hermaphroditism. The recent development of 3D and 4D ultrasound technology may be relevant to a more clearly identification of the fetal uterus. Volume contrast imaging (VCI) provides high contrast images by the realization of thick slices of the region of interest (ROI) thereby providing a clearer picture of the fetal uterus. The multiplanar mode may also facilitate the differentiation of the fetal uterus from the other intra-pelvic organs by offering images in three perpendicular planes. Finally, the tomographic ultrasound imaging (TUI) mode offers the ability to display on a single panel numerous 2-dimensional sections, as obtained using computed tomography imaging.

L'apoptose des cellules de la granulosa peut-elle être considérée comme un marqueur prédictif du succès de la fécondation in vitro ?

During in vitro fertilization (IVF) morphological criteria are the only means usable today to select embryos before their uterine transfer in order to obtain pregnancy with the best chances of success. Since several years many attempts have been made to find more functional means. Quantification of apoptosis of granulosa cells has been proposed for this purpose. The aim of this review is to take stock of our knowledge on apoptosis and its mechanisms in granulosa cells and to analyse how quantification of these apoptotic cells could be a reliable and predictive marker of success for an attempt of an IVF in terms of pregnancy.

[Screening and timing for the delivery of fetuses with intrauterine growth restriction of vascular origin]

The prenatal management of fetuses with intrauterine growth restriction (IUGR) has been a matter of perpetual evolving in obstetrics and has been the topic of numerous studies. The management of IUGR fetuses is currently available in tertiary centres using fetal heart monitoring, short term variability, or doppler investigation of the umbilical artery, ductus venosus and middle cerebral artery. The aim of the prenatal management is to detect anomalies that may predict severe fetal hypoxemia. On the other hand, any efforts should focus on the possibility to delay the time for delivery as gestational age at delivery together with birth weight appear to be essential parameters of the postnatal outcome.

Contribution of three-dimensional volume contrast imaging to the sonographic assessment of the fetal uterus

OBJECTIVE

To investigate the contribution of volume contrast imaging (VCI) in assessing the fetal uterus in normally developed female fetuses.

METHODS

The pelvis of 38 normal female fetuses was examined at 20-22 and 32-34 weeks' gestation using both conventional two-dimensional (2D) ultrasound and VCI on the same transverse or oblique longitudinal view of the fetal pelvis. Two experienced sonographers evaluated the ability of both techniques to image the fetal uterus. Results were compared by kappa index to evaluate the interobserver variability.

RESULTS

A clear picture of the fetal uterus was obtained in 50% and 82-87% of the cases at 20-22 weeks' gestation and in 80-85% and 95-100% of the cases at 32-34 weeks' gestation using conventional 2D ultrasound and VCI, respectively. There was moderate to good agreement of uterus visualization between the two observers, with kappa values ranging from 0.43 to 0.65. The lower level of agreement was obtained for conventional 2D ultrasound during the second trimester.

CONCLUSIONS

Our results suggest that VCI may be successfully applied to prenatal ultrasonography of the fetal pelvis anatomy. By enhancing the contrast between the intrapelvic organs, VCI provides a clearer picture of the fetal uterus.

[Recording expulsive forces during childbirth using intercostal muscle electromyogram: a pilot study]

OBJECTIVE

The expulsive forces of childbirth can be included among the many potential risk factors implicated in the subsequent development of perineal disorders. The objective of this study was to devise a non-invasive way to measure abdominal pushing that would accurately represent the expulsive forces during childbirth.

PATIENTS AND METHODS

By means of intravesical and intrauterine manometry, and electromyography (EMG) of intercostal muscles, we quantified these forces in 21 women during vaginal delivery.

RESULTS

A mixed Ancova model showed the integral of intravesical pressure to be significantly associated (P<0.001) with the integral of intercostal muscle electrical activity during the first 6 uterine contractions during the phase of fetal expulsion.

DISCUSSION AND CONCLUSION

Electromyography is a non-invasive measurement that can replace intravesical determinations to quantify these forces as it reflects the real intra-abdominal pressure.

Hystéroscopie diagnostique et risque de contamination péritonéale par les cellules tumorales

Questions have been raised about the safety of diagnostic hysteroscopy preceding surgical treatment of endometrial carcinoma. Several studies showed that the risk of a positive cytology among patients presenting endometrial adenocarcinoma was increased after diagnostic hysteroscopy, suggesting a peritoneal dissemination of tumor cells due to the exploration. We studied this hypothesis on the basis of a systematic review of the scientific data. Five studies fulfilling inclusion criteria have been selected and have been introduced into a fixed model of meta-analysis. On a total of 756 studied patients, 79 presented a positive peritoneal cytology. The diagnostic hysteroscopy did not increase significantly the risk of abdominal dissemination of tumor cells, the peritoneal cytology being positive among 38 patients in the group having undergone this intervention vs 41 patients in the control group (OR = 1,64; 95% CI: 0,96-2,80). In conclusion, no formal evidence is currently available concerning the role of diagnostic hysteroscopy on the frequency of peritoneal dissemination of tumor cells, or on the vital prognosis of the patients presenting with endometrial carcinoma. From the data available, there is not any reason to avoid diagnostic hysteroscopy in the initial workup of endometrial cancer.

[Preterm corticosteroid therapy and fetal immobility. Case report]

We report a case of fetal immobility following antenatal corticosteroid therapy administered to women in thirty weeks at risk of preterm labor. The short-term side effect of corticosteroid, a decrease in fetal heart rate variation are well known. This case report presents the difficulty of therapy choice in front of fetal immobility and acute fetal distress. We chose a medical supervision. A review of the literature suggests other criteria, such as Doppler of umbilical artery, which could help therapeutical choice.

Prospective 3D ultrasonographic evaluation of immediate postpartum urine retention volume in 100 women who delivered vaginally

Our objective was to determine the reproducibility and validity of urine retention volumes measured by 3D ultrasonography (3D-US) 2 h postpartum. This was a longitudinal prospective study of 100 women who delivered vaginally. Each woman underwent five successive urine retention measurements with the Bladder Scan 2 h after vaginal delivery, followed by transurethral catheterization to determine the real volume. The reproducibility of only the last four scan values was analyzed with an intraclass correlation coefficient, and that of determinations 4 and 5 with a Bland-Altman plot. The validity of the device was similarly evaluated using the mean four-scan and real values. Pearson's correlation coefficient was calculated and a least-trimmed squares robust linear-regression model was used. All tests were two-sided with a 5% alpha risk. Results showed that 3D-US measurements were highly reproducible, with an intraclass correlation coefficient of 0.974 (95% CI:0.964-0.981). 3D-US also accurately estimated the real urine volume (intraclass correlation coefficient 0.924; 95% CI:0.888-0.949), but tended to underestimate by about 6.8%. The between-technique Pearson correlation coefficient was 0.94 (P < 0.0001) and the regression analysis gave an R2 of 0.914. Urine retention volumes exceeded 500 ml in 55 women, and 11 in 7. We concluded that 3D-US was reliably able to measure postpartum urine retention volume.

Hepatitis C virus detection in follicular fluid and culture media from HCV+ women, and viral risk during IVF procedures

BACKGROUND

Hepatitis C virus (HCV) has been detected in sperm, but no data are available on follicular fluid (FF) collected on IVF procedures. The aim of this study was to: (i) search for HCV RNA in FF and in culture media at each step of IVF undergone by HCV(+) women; (ii) investigate the impact of blood contamination of FF induced by vascular injury associated with transvaginal ovarian puncture; (iii) assess risk for the embryo and the impact on the contamination rate of the newborn; and (iv) determine the viral risk presented by these fluids in order to define guidelines for the laboratory.

METHODS

FF from 22 IVF procedures performed in 17 HCV(+) women were classified as either clear, lightly bloody or bloody FF. Oocytes from each FF were washed and incubated in separated fertilization media. At 20 h after puncture (day 1), the fertilized oocytes were washed and transferred to fresh media until embryo transfer. HCV RNA was detected and quantified in FF and media using Cobas Amplicor and Cobas Monitor HCV RNA kits.

RESULTS

HCV RNA was positive in 39 of 44 FF samples, and viral loads increased with blood contamination. At day 1, after rinsing of oocyte-cumulus complexes, only 8 of 44 media were still positive. Viral loads were quantified in 5 of 8 positive media, were below the test sensitivity threshold in 4 of 5 HCV RNA-positive media, and just above it in the fifth medium. The day of transfer HCV RNA was undetectable in all media.

CONCLUSIONS

HCV RNA was detected in 89% of FF irrespective of the degree of blood contamination, and in 25% of the media at day 1. FF must be considered as potentially infected. Blood contamination increases HCV load in the FF. Rinsing oocytes seems significantly to discard the HCV RNA. It is too early to assess the impact of IVF on the contamination rate of HCV mothers' offspring. After counselling, attempting IVF in HCV(+) women is justified. Universal guidelines prevent nosocomial infection, and IVF does not specifically increase the professional risk.

Pregnancy outcome after laparoscopic and laparoconverted myomectomy

OBJECTIVE

To compare fertility and pregnancy-related complications after laparoscopic and laparoconverted myomectomy.

METHODS

Retrospective analysis of 106 infertile women with uterine leiomyomas, of whom 88 women underwent laparoscopic myomectomy and 18 laparoconversion.

RESULTS

There was no difference in the patients' baseline characteristics or the mean number of fibroids between the laparoscopic and laparoconversion groups. The mean (+/-S.D.) diameter of the largest fibroid in the laparoscopic and laparoconversion groups was 6.2+/-1.8 and 8.1+/-1.4 cm, respectively (P<0.001). There was no difference in operating time between the two groups. The hospital stay was shorter in the laparoscopic group: 3.0+/-1 versus 5.5+/-1 days (P<0.001). The mean follow-up in the laparoscopic and laparoconversion groups was 27.3+/-7.0 and 32.0+/-3.1 months, respectively (NS). No difference in the pregnancy rate was noted between the laparoscopic and laparoconversion groups (48 and 56%, respectively). The mean time before conception in the laparoscopic and laparoconversion groups was 7.5+/-2.6 and 15.1+/-2.4 months, respectively (P<0.001). There was no difference between the two groups as regards the rates of pregnancy-related complications and vaginal delivery. No uterine rupture occurred.

CONCLUSION

Laparoscopic myomectomy is feasible and safe, and should be considered for infertile women with uterine fibroids. Fertility and pregnancy outcomes following laparoscopic myomectomy are comparable with those following myomectomy after laparoconversion.

A modified RT-PCR technique to screen for viral RNA in the semen of hepatitis C virus-positive men

BACKGROUND

Our objective was to use an adapted RT-PCR technique to assess the presence of hepatitis C virus (HCV) in semen and also in different density gradient semen fractions collected from men with chronic viral hepatitis participating in an assisted reproduction programme.

METHODS

This study included 50 semen samples from 35 HCV(+) men, with active viral replication assessed by RT-PCR, collected the day of oocyte retrieval and used for assisted reproduction. These samples were subjected to standard assisted reproduction sperm preparation conditions, using density-gradient centrifugation with 45 and 90% layers. Aliquots of semen, 45 and 90% fractions, and embryo culture media were frozen at -80 degrees C for subsequent virological analyses. All aliquots were tested with a commercially available HCV RNA assay, adapted for use with semen after a number of technical changes. This assay yielded a sensitivity of 50-100 HCV RNA copies/ml and strongly diminished the effect of seminal amplification inhibitors.

RESULTS

HCV RNA was detected in 7/50 (14%) semen samples tested, 5/35 (14.3%) men. HCV RNA was found in only 1/50 45% fractions but never in the 90% fraction or embryo culture media. Sera from 3/5 men contained 3.19-7.40 x 10(5) IU/ml, while the two others had 4.5 and 11.7 x 10(6) IU/ml. However, HCV RNA was quantified at <600 IU/ml in the HCV(+) semen of these five patients. The ongoing pregnancy rate was of 20% (10/50) with one delivery at the time of the present report. No anti-HCV antibody was found in any of the women or the newborn.

CONCLUSIONS

Although HCV is present at low concentrations in the semen of a few HCV(+) patients, no purified sperm fraction (i.e. 90% fraction) used in assisted reproduction was HCV(+) and no seroconversion was observed in the women and the newborn, thereby suggesting a very low risk of virus transmission. Nevertheless, because the presence of HCV in semen implies a possible risk of nosocomial contamination, safety regulations must be strictly applied in assisted reproduction laboratories.

Effects of hepatitis C virus on the apoptosis percentage of granulosa cells in vivo in women undergoing IVF: preliminary results

BACKGROUND

The aim of this study was to investigate the relationship between the apoptosis percentage of human luteinized granulosa cells (GC) and the presence of hepatitis C virus (HCV) in follicular fluid (FF).

METHODS

GC were isolated from FF of 12 women undergoing 12 IVF cycles: six were HCV+ with active viral replication and six HCV- serving as controls. No male partner was HCV+. HCV detection and quantification were assessed by reverse transcriptase-polymerase chain reaction in serum, FF and embryo-incubation medium. GC were analysed by flow cytometry after propidium iodide staining to measure the percentages of apoptotic GC. Routine IVF parameters were tabulated.

RESULTS

Mean +/- standard deviation (SD) serum and FF HCV viral loads were 3.58 +/- 4.25 x 10(6) and 0.14 +/- 0.10 x 10(6) IU/ml respectively. Mean percentages of apoptotic GC from HCV+ and HCV- women were 3.08 +/- 1.14 and 3.14 +/- 1.40% respectively. No statistically significant difference was found between these two groups concerning GC apoptosis and when we compared all IVF parameters. No HCV RNA was detected in embryo incubation media after 2 days of culture.

CONCLUSIONS

Comparing GC apoptosis percentages and usual IVF parameters in the HCV+ group versus the HCV- group, our preliminary study shows that active chronic HCV infection does not affect follicle development and IVF outcome in HCV+ women undergoing IVF. Furthermore, the risk of newborns becoming HCV-infected might not be increased by assisted reproductive technologies when performed in couples in which women are HCV+ and men HCV-.

Induced apoptosis and expression of related proteins in granulosa cells from women undergoing IVF: a preliminary study

BACKGROUND

Because apoptosis may be involved in the outcome of IVF, the expression of pro- and anti-apoptosis proteins in a model of induced granulosa cell (GC) apoptosis was evaluated in 25 women with normal FSH levels undergoing IVF.

METHODS

After 1 day of culture, apoptosis was induced with interferon (IFN)-gamma (200 IU/ml), followed 24 h later by an agonistic anti-Fas antibody (0.5 microg/ml). On day 3, apoptotic GC, identified by chromatin condensation and/or nuclear fragmentation after DAPI staining, were counted among 1000 cells in randomly chosen fields under UV microscopy, and enabled allocation of women into two groups with either low (group 1) or high (group 2) percentages of apoptosis (11.6 +/- 4.8 and 59.5 +/- 14.8% respectively; P < 0.001). Immunoblotting was used to evaluate the following in proteins: poly (ADP-ribose) polymerase (PARP), caspases 8 and 3, Bcl-2, heat shock protein (HSP) 70, Bax, Bak and Stat-1 (a protein known to be inducible by IFN-gamma).

RESULTS

Based on densitometric analysis of immunoblots, the PARP 116 kDa bands were respectively 4.3- and 33.3-fold lower for treated groups 1 and 2. Caspase 8, caspase 3 and HSP70 were expressed slightly less in treated group 2 than treated group 1. Densitometric analysis of bands corresponding to Bcl-2 showed respectively for treated groups 1 and 2, 3.2- and 2.5-fold decreases. Bak expression was similar in both control groups, and comparably lower in the two treated groups. With regard to Stat-1, densitometry showed 3.3- and 1.3-fold increases respectively in treated groups 1 and 2.

CONCLUSIONS

These results suggested that Fas-mediated apoptosis of GC is accompanied by significant changes in proteins acting in apoptosis, and that this type of programmed cell death might play a potential prognostic role for women undergoing IVF.

Determinants of pregnancy rate and obstetric outcome after laparoscopic myomectomy for infertility

OBJECTIVE

To determine the effect of myomectomy on infertility and to assess the factors influencing reproductive outcome.

DESIGN

Retrospective study.

SETTING

Tertiary care center.

PATIENT(S)

One hundred and three infertile women with uterine leiomyoma who had had infertility >2 years and a follow-up time >12 months were enrolled. Follow-up was complete for 88 patients, including 28 (31.8%) with primary infertility and 44 (50%) with unexplained infertility. The mean (+/-SD) age of the patients was 36.1 +/- 2.1 years.

INTERVENTION(S)

Laparoscopic myomectomy.

MAIN OUTCOME MEASURE(S)

Pregnancy rate according to patient and fibroid characteristics.

RESULT(S)

Forty-two patients became pregnant (40.7%). The mean (+/-SD) delay in conception was 7.5 +/- 2.6 months. Nearly 80% of the women conceived spontaneously. Of 44 pregnancies in 42 women, 36 live newborns were delivered. No dehiscence of uterine scar occurred. The pregnancy rate was significantly higher in women <35 years of age or <3 years of infertility. Women with unexplained infertility had higher pregnancy rate than did women with multifactorial infertility (P<.001). No difference was noted in pregnancy rates according to fibroid characteristics.

CONCLUSION(S)

Fertility and pregnancy after laparoscopic myomectomy depend primarily on patient age, duration of infertility before myomectomy, and existence of associated infertility factors.

Vascular endothelial growth factor, platelet endothelial cell adhesion molecule-1 and vascular cell adhesion molecule-1 in the follicular fluid of patients undergoing IVF

BACKGROUND

The aim of our study was to measure concentrations of vascular endothelial growth factor (VEGF), platelet endothelial cell adhesion molecule-1 (PECAM-1) CD31 and vascular cell adhesion molecules (VCAM-1) in the follicular fluid of women treated with assisted reproduction technology to determine whether these proteins might be outcome markers.

METHODS

Follicular fluid was collected from 75 patients < or =40 years undergoing oocyte retrieval procedures at our tertiary hospital during 1997 and 1998: 50 with tubal disease, 12 with endometriosis, and 13 whose partners had been diagnosed with severe oligoasthenoteratozoospermia. This retrospective analysis considered age and information about treatment and outcome for all these women who had undergone fewer than three assisted reproduction attempts.

RESULTS

Nineteen women became pregnant (defined by human chorionic gonadotrophin concentrations and embryonic cardiac activity 1 month after follicular aspiration); 56 did not. Women did not differ significantly in their follicular fluid concentrations of VEGF, sCD31 and VCAM-1 according to cause of infertility, or assisted reproduction outcome, or age. Follicular fluid concentrations of VEGF were significantly correlated with the number of gonadotrophin ampoules administered (P < 0.012), and follicular fluid concentrations of sVCAM-1 with the fertilization rate (P < 0.01). Follicular fluid concentrations of VEGF and sVCAM-1 were also correlated (P < 0.007).

CONCLUSIONS

Our results do not suggest that VEGF, CD31, or sVCAM-1 in follicular fluid predict assisted reproduction outcome, especially among patients < or =40 years old. The correlation of a high fertilization rate and sVCAM-1 in follicular fluid suggests that sVCAM-1 might be a marker of fertilization.

[Myoma and infertility: analysis of the literature]

The influence of myomas on reproduction has been clearly demonstrated, however their effects on fertility remain debated. The aim of this review, between January 1988 and December 2000, was to clarify the relation between myoma and fertility, and to assess pregnancy rates after myomectomy in infertile patients. Spontaneously, 54 publications were selected and 40 eligible. No study compared pregnancy rates with or without myomas. Pregnancy rates after myomectomy varied between 9.6% and 76.9%, with descriptive series. In medically assisted procreation, five publications were eligible. Myoma presence was associated with decreased pregnancy rates. Hysteroscopic sub-mucous myoma resection increased pregnancy rates. Relation between myoma and sterility is probable, however no proof was obtained. Myomectomy efficacy has not been statistically proven, but spontaneously almost 60% of patients became pregnant 24 months after surgery. Decreased pregnancy rates are observed when other infertility factors are associated. Concerning myomectomy in medically assisted procreation, conflicting results are available. Prospective randomised studies are needed.

[Management of pregnant women infected with HIV at Bichat Hospital between 1990 and 1998: analysis of 202 pregnancies]

OBJECTIVE

To describe medical and obstetrical prenatal care of pregnant women infected by HIV-1 emphasizing the role of cesarean section.

DESIGN

A retrospective study of 202 pregnancies followed between 1990 and 1998 in a french hospital in Paris.

RESULTS

56.9% of the women were born in subsaharian Africa; 80.2% were infected by sexual intercourse and the seropositivity was discovered during the pregnancy in 51% of the cases. Viral coinfections by hepatitis B virus, hepatitis C virus and Human papillomavirus were found respectively in 14.7%, 16.5% and 13% of the pregnancies. Prematurity occurred in 15% of the deliveries. Efficacy of antiretroviral therapy was confirmed in this study: 5.7% of the children were infected despite the antiretrovial treatment versus 19.3% without treatment (p < 0.03). Prophylactic cesarean section was proposed to the patients since 1994; the morbidity of cesarean was 8.8% (69 cesarean sections).

CONCLUSION

The policy of the association of prophylactic cesarean section and monotherapy by Zidovudine is validated by recent studies. The extension of prophylatic cesarean section to all the pregnant women infected by HIV is proposed. However the evaluation of the morbidity of the cesarean section in HIV infected women needs a prospective case-control study.

APC resistance and third-generation oral contraceptives: Acquired resistance to activated protein C, oral contraceptives and the risk of thromboembolic disease

Using a newly-developed technique, a severe acquired plasma resistance to activated protein C has been described in women using third-generation (rather than second-generation) oral contraceptives. The following items are discussed: (i) the technical parameters used to appreciate the effect of activated protein C induce a bias of interpretation, the mean intrinsic effect of activated protein C, in plasmas from women on second or third-generation oral contraceptives being strictly identical; (ii) there are no data available to show that this assay can indicate a thromboembolic risk in asymptomatic women on oral contraceptives; and (iii) this assay is a global and non-specific test, basically sensitive to the plasma concentrations of many coagulation factors which are increased or decreased by oestrogens and progestogens. For instance protein S, in which oral contraceptive-induced modifications account for the differential effect of oral contraceptives on Rosing's assay, but which modifications are not related to the thromboembolic risk of oral contraceptives. The androgenic potential of the progestogen may counteract the effect of oestrogens in the test. More generally, in such a complex situation in which there is a 'modification of the modification', there is no haemostasis-related test which provides a risk indicator for thrombosis. Based on testing of the plasma response to activated protein C, it is impossible to state that third-generation oral contraceptives induce a more important thromboembolic risk than oral contraceptives containing a more androgenic progestogen.

Safety of cryopreservation straws for human gametes or embryos: a preliminary study with human immunodeficiency virus-1

The aim of this preliminary experimental study was to test the stability of cryopreservation straws to human immunodeficiency virus-1 (HIV-1). Three kinds of straws were tested: four polyvinyl chloride (PVC), four polyethylene terephthalate glycol (PETG) and 20 high-security ionomeric resin (IR). The PVC and PETG straws were sealed ultrasonically, and the IR straw by thermosoldering. Each sealed straw was cut in half to produce two demi-straws and then filled with 100 microl of HIV-1-containing supernatant (reverse transcriptase activity: 15 000 c.p.m./50 microl). The unsealed cotton end of PVC and PETG straws and the two halves of the IR straws (cotton and plastic plug ends) were tested. Each demi-straw was two- thirds submerged in RPMI medium at 37 degrees C, and RPMI samples were withdrawn on days 3, 7 and 11. Viral RNA was extracted from the medium and then amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) followed by nested PCR using primers specific to HIV-1 protease. On day 7, no HIV-1 RNA was detected in any of the different samples of medium that had surrounded the unsealed PVC and PETG straws with cotton ends, but three IR specimens were positive. On day 11, PVC and PETG remained negative but HIV-1 RNA was detected in RPMI samples for two more IR demi-straws (n = 5). In conclusion, under these experimental conditions (at 37 degrees C), the unsealed cotton end PVC, PETG and thermosoldered cotton end IR demi-straws appeared to be safe for HIV-1, while IR straws, sealed or unsealed with a plastic plug and with unsealed cotton ends, leaked.

Are sphincter defects the cause of anal incontinence after vaginal delivery? Results of a prospective study

PURPOSE

Anal incontinence affects approximately 10 percent of adult females. Damage to the anal sphincters has been considered as the cause of anal incontinence after childbirth in the sole prospective study so far available. The aims of the present study were to determine prospectively the incidence of anal incontinence and anal sphincter damage after childbirth and their relationship with obstetric parameters.

METHODS

We studied 259 consecutive females six weeks before and eight weeks after delivery. They were asked to fill in a questionnaire assessing fecal incontinence. Anal endosonography (7-10 MHz) was then performed. Two independent observers analyzed internal and external anal sphincters.

RESULTS

A total of 233 patients (90 percent) were assessed, of whom 31 had cesarean section. De novo sphincter defects were observed in 16.7 percent (14 percent external, 1.7 percent internal, and 1 percent both) in the postpartum period only after vaginal delivery. These disruptions occurred with the same incidence after the first and the second childbirth. Independent risk factors (odds ratio; 95 percent confidence interval) for sphincter defect were forceps (12; 4-20), perineal tears (16; 9-25), episiotomy (6.6; 5-17), and parity (8.8; 4-19) as revealed by multivariate analyses. The overall rate of anal incontinence was 9 percent and independent risk factors (odds ratio; 95 percent confidence interval) involved forceps (4.5; 1.5-13), perineal tears (3.9; 1.4-10.9), sphincter defect (5.5; 5-15), and prolonged labor (3.4; 1-11). Among these patients only 45 percent had sphincter defects.

CONCLUSION

Anal incontinence after delivery is multifactorial, and anal sphincter defects account for only 45 percent of them. Primiparous and secundiparous patients have the same risk factors for sphincter disruption and anal incontinence. Because external anal sphincter disruptions are more frequent than internal anal sphincter damage, surgical repair should be discussed in symptomatic patients.

[Relationship between human immunodeficiency virus and sperm--implications in medically assisted procreation]

The number of HIV-sero-discordant couples (man HIV+, woman HIV-) asking for assisted reproductive technologies (ART) has been increasing more and more since the efficiency of antiretroviral therapy was clinically proven. Long-term survey and amelioration of life quality in treated HIV-seropositive patients have induced in these couples a strong wish to conceive but they expected the most reduced risk of viral contamination. Epidemiologic data concerning HIV transmission during episodic unprotected sexual acts showed an elevated annual seroconversion rate which justifies that since 1992, European biologists specialized in human reproduction have proposed to carry out ART using intrauterine insemination (IUI) with prepared sperm in the population of couples where the man is HIV-seropositive. In spite of adapted technologies of sperm preparation, presence of HIV nucleic acids was demonstrated in purified spermatozoon (SPZ) fractions, resulting from residual free virus or virus linked to SPZ or residual infected cells, not completely eliminated. However, approximatively 2000 IUI were carried out with an HIV-controlled sperm treatment and no female and newborn seroconversions were reported. Even if the total lack of risk is impossible to obtain, a strict method of infected sperm preparation associated with sensitive virological techniques should permit us to obtain a minimal risk of contamination of women after IUI. In vitro fertilization (IVF) with or without microinjection allowed us to obtain the same results but they should be confirmed by further studies to be more relevant. These European workings, associated to a clear legal regulation in France, permit us to considerate that carrying out ART in HIV-sero-discordant couples in which the man is HIV-seropositive is allowable regarding both the viral problem and eventual sterility.

Fertility after hysteroscopic myomectomy: effect of intramural myomas associated

OBJECTIVE

The aims of this retrospective study were to evaluate the subsequent fertility and outcome of pregnancies after hysteroscopic myomectomy according to (a) the characteristics of submucous myomas and (b) the association with intramural myomas.

MATERIALS AND METHODS

From July 1994 to June 1997, 119 patients had hysteroscopic myomectomy including 31 infertile women. Among these 31 patients, the mean number of removed myomas by hysteroscopy was 1.4 (range 1-4) and the mean diameter of fibroid was 20 mm (range 10 to 50).

RESULTS

Eleven out of 31 women (35.5%) became pregnant. Thirteen pregnancies were observed including nine term deliveries, three miscarriages and one premature labor at 24 weeks of amenorrhea. A difference in delivery rate was found between patients with one submucous myoma resected and those with two or more (p=0.02). No difference in pregnancy and in delivery rates was observed according to size and location of submucous myomas. In contrast, in patients without intramural myomas, the delivery rate (p<0.03) was significantly greater and the delay of conception (p=0.05) was significantly shorter than those found in patients with intramural myomas.

CONCLUSION

Our study suggest that fertility after hysteroscopic myomectomy depend on (a) the number of submucous myomas resected and (b) the association with intramural fibroids.

[Postpartum sphincter rupture and anal incontinence: prospective study with 259 patients]

AIMS

Damage to the anal sphincter has been considered as the cause of anal incontinence after childbirth. The aims of the present study were to determine prospectively the incidence of anal incontinence and anal sphincter damage after childbirth, and their relationship with obstetric parameters in France.

PATIENTS AND METHODS

We studied 259 consecutive women six weeks before and eight weeks after delivery. They were asked to fill out a questionnaire dealing with faecal and urinary incontinence. Anal endosonography (B&K 7-10 MHz) was then performed. Two independent observers analyzed internal and external anal sphincters.

RESULTS

Two hundred and thirty-three women (90%) were assessed, among whom 31 had had a caesarean section. De novo sphincter defects were observed in 19.3% (39 patients) in the postpartum period only after vaginal delivery (202 patients). These disruptions occurred with the same incidence after the first and second childbirth. Independent risk factors (odds ratio; 95% confidence interval) for sphincter defect were forceps (odds ratio 11.9; 4.8-33.3), perineal tears (odds ratio 16.1; 4.4-83.9), episiotomy (odds ratio 6.6; 1.7-34.2), and pauciparity < or = 2 (odds ratio 8.8; 1-78.3), as revealed by multivariate analyses. The overall rate of de novo anal incontinence was 9% (20 patients), and independent risk factors involved forceps (odds ratio 4.5; 1.5-13), perineal tears (odds ratio 3.9; 1.4-10.9), de novo sphincter defect (odds ratio 5.5; 5-15) and prolonged labor (odds ratio 3.4; 1-11). Among the 20 women who had de novo anal incontinence, only 45% (9 patients) had sphincter defects.

CONCLUSION

De novo anal incontinence after delivery is multifactorial and anal sphincter defects account only for 50% of them. Primiparous and secundiparous women have the same high-risk factor for sphincter disruption and anal incontinence. Since external anal sphincter disruptions are more frequent than internal anal sphincter damage, surgical repair should be discussed.

The role of selective prescribing in the increased risk of VTE associated with third-generation oral contraceptives

In the early 1960s, it became apparent that oral contraception (OC) with oestroprogestogens increased the cardiovascular, venous thromboembolic (VTE), myocardial infarction (MI) and cerebrovascular accident (CVA) risk. The change in medical prescribing patterns, the reduction in ethinyloestradiol dosage and the use of less androgenic progestogens made prescribers confident that the risks would subsequently decrease. At the end of 1995 and early 1996, four publications called into question that optimism by showing that third-generation pills induced a two-fold increase in VTE risk compared with second-generation pills. A biological rationale was due to be announced later. Since then, re-analysis of the data has shown that the thrombotic risk factors are increased in third-generation OC users but, more importantly, that those users (unlike those using second-generation pills) are the women who have not had the opportunity of revealing a latent thrombophilia and are, therefore, at a greater risk of expressing it during third-generation OC intake. When these data are considered, the difference between second- and third-generation OC users in terms of VTE risk is completely destroyed. In addition and although the risk factors (smoking in particular) are concentrated in third-generation OC users, the MI risk is less in those users than in second-generation pill users. This is particularly true in the presence of a risk factor such as smoking. No difference in risk has been observed for CVA in the general population between second- and third-generation OC users, but once more among smoking women the risk is lower with third-generation OC.

[Laparoscopic surgery during the second trimester of pregnancy: indications, technique, and fetal repercussions. Report of nine cases and review the literature]

Non-obstetric abdominopelvic surgery during pregnancy is associated with a considerable materno-foetal complication rate related to the delayed diagnostic and therapeutic management and the severity of the underlying disease. Based on retrospective analysis of 9 laparoscopies performed during the second trimester of pregnancy between the months of January 1994 and October 1996 in the Gynaecology and Obstetrics Department of Hospital Bichat, the authors study the feasibility of this technique. They report 9 cases of abdominopelvic disease, in which laparoscopy allowed a diagnostic and therapeutic approach: 6 cases of adnexal disease, 2 appendicular syndromes and one diagnostic laparoscopy. The maternal and obstetric course was favourable in each case. Several cases of laparoscopic appendicectomy, cholecystectomy, and adnexal surgery during pregnancy have been published since 1990. The main reasons theoretically contraindicating laparoscopy after the first trimester of pregnancy are the risk of uterine injury and the foetal risk during creation of the pneumoperitoneum. Experimental data are limited, but the increased intra-abdominal pressure and the use of CO2 do not appear to have any harmful effects in animals (foetal lambs). By respecting a certain number of technical precautions, laparoscopy during the second trimester of pregnancy can constitute a legitimate diagnostic and therapeutic approach.

The reasons for termination of pregnancy in the third trimester

OBJECTIVE

To analyse the process in making decisions leading to termination of pregnancy in the third trimester and to evaluate the maternal morbidity associated with this procedure.

DESIGN

Retrospective study.

SETTING

The Maternité Port Royal University Hospital, Paris, France.

POPULATION

A consecutive series of 956 terminations of pregnancy performed for fetal anomalies in singleton pregnancies, 305 of which were in the third trimester and 651 in the second.

MAIN OUTCOME MEASURES

Indications for termination of pregnancy; process leading to late termination of pregnancy; maternal morbidity.

RESULTS

One hundred and thirteen (37%) third trimester terminations of pregnancy were associated with false negative resulted from the results of earlier screening tests. In 15 terminations (5%), the decision was postponed, although the poor fetal prognosis was established earlier. In 55 (18%) the diagnosis was not possible earlier than the third trimester, and in 122 (40%) the diagnosis was possible earlier but the poor prognosis for the fetus was not established until the third trimester. Maternal morbidity due to termination of pregnancy was similar in the second and third trimester.

CONCLUSION

One-third of late terminations of pregnancy could have been avoided by more efficient screening in the second trimester. However, because fetal prognosis is not always clear when a malformation is diagnosed, postponing the decision until fetal development allows more thorough evaluation and may avoid unnecessary termination of pregnancy in the second trimester. This could be the main beneficial aspect of not setting a limit to the gestational age for performing termination of pregnancy.

[Mechanical and metabolic complications of hysteroscopic surgery: report of a retrospective study of 352 procedures]

Our objective was to determine, in a retrospective study of 352 operative hysteroscopies: (a) the rates and the types of complications and (b) the risk factors of peroperative perforations. The most important complications represented 1.7% including two haemorrhage, one symptomatic metabolic abnormalities and three uterine perforations with bowel injuries (0.8%). Furthermore, minor complications were observed in 9.3% including non symptomatic metabolic abnormalities (5.5%) and uterine perforations without visceral injury. Among mechanical complications, the majority were uterine perforations (4%). No relation was found between menopausal status of the patients and the occurrence of uterine perforation. In contrast, the perforation rate was statistically greater in patients treated for synechia than those found for myoma (p < 0.0001). Furthermore, the perforation rate was statistically higher for resection of myomas as compared with endometrial resection (p < 0.0001) or polyp resection (p < 0.0008). Moreover, in our experience, the perforation rate depended on hysteroscopic experience of surgical operators.

Management and outcome of borderline ovarian tumors incidentally discovered at or after laparoscopy

BACKGROUND

To evaluate in a series of patients with borderline ovarian tumors the clinical findings and the outcome after laparoscopic management.

METHODS

Retrospective study of 25 patients with borderline ovarian tumors first treated by laparoscopic approach.

RESULTS

Thirteen patients had mucinous tumors and 12 had serous tumors. Twenty-one patients had ultrasound examination which detected 24 ovarian cysts including multilocular cysts in 50% of cases and unilocular sonolucent cysts in 25% of cases. The serum CA 125 and CA 199 levels were elevated in 30.7% and 23% respectively. Among the 25 patients first treated by laparoscopic approach, 24 had stage I disease: six of them had cystectomy, seven unilateral salpingo-oophorectomy, two bilateral salpingo-oophorectomy and two laparoscopic hysterectomy with bilateral salpingo-oophorectomy. Seven patients had laparoconversion for presumption of ovarian cancer (5) and failure of laparoscopic procedure (2). One patient with stage III disease had laparoscopic biopsies and subsequent laparotomy. Among the 25 patients, 15 had conservative treatment and 10 had radical treatment. Three recurrences occurred after cystectomy. The mean follow-up was 41 months. Twenty-three patients were alive without evidence of disease, one died of intercurrent disease and one patient was lost to follow-up.

CONCLUSION

Our data suggest that the laparoscopic approach to borderline ovarian tumors is possible in early stage disease but associated with a high risk of recurrence after cystectomy.
