OBJECTIVE: To present our experience in hysteroscopic removal of abnormally invasive placenta (AIP) residuals using bipolar energy. DESIGN: Case series. SETTING: University hospital. POPULATION: Sixteen patients with AIP residuals after 17 pregnancies. METHODS: Cases were identified by ultrasound, treated with hysteroscopic bipolar electrosurgery and oral contraceptives, and followed up by ultrasound or hysteroscopy. Nine subsequent pregnancies were described. MAIN OUTCOME MEASURES AND RESULTS: Complete removal of AIP residuals was achieved by hysteroscopic bipolar electrosurgery in all cases except one. No peroperative complications occurred. AIP residual recurred in one patient after a subsequent pregnancy and was successfully treated using the same procedure. CONCLUSIONS: AIP residual is a rare condition. Management by hysteroscopic resection using bipolar energy is save and feasible. [less ▲]

Menstrual endometrial breakdown induced by estradiol and progesterone withdrawal is regularly attributed to vasospasm of spiral arteries causing ischemia and hypoxia. We investigated whether hypoxia actually occurred in an in vivo model of menstruation. Three complementary approaches were used to look for signs of hypoxia in fragments of human functionalis xenografted to ovariectomized immunodeficient mice bearing pellets-releasing estradiol and progesterone, and then deprived of ovarian steroids. Hormone withdrawal 21 d after grafting induced menstrual breakdown and MMP expression within 4 d. Local partial oxygen pressure (pO2) was measured by electron paramagnetic resonance using implanted lithium phtalocyanine crystals. In mice with hormone maintenance until sacrifice, pO2 was low one week after grafting (14.8+/-3.4 mmHg) but increased twofold from the second week when tissue was largely revascularized. After 3 wk, pO2 was not modified by hormone withdrawal but was slightly increased on hormone reimpregnation 4 d after removal (34.7+/-6.1 mmHg) by comparison with hormone maintenance (27.1+/-8.6 mmHg). These results were confirmed using fluorescence quenching-based OxyLite measurements. In a further search for signs of hypoxia, we did not find significant HIF1-alpha immunostaining, nor pimonidazole adducts after hormone withdrawal. We conclude that hypoxia is not needed to trigger menstrual-like tissue breakdown or repair in human endometrial xenograft.-Coudyzer, P., Lemoine, P., Jordan, B.

BACKGROUND: There is currently no consensus about indications for surgery for infertility associated with colorectal endometriosis. The aim of this study was to evaluate cumulative pregnancy rates (CPRs) after ICSI-IVF cycles in patients with colorectal endometriosis and to identify determinant factors of fertility outcome. METHODS: Prospective longitudinal multicentre study from January 2005 to June 2011. We included 75 patients with colorectal endometriosis and proved infertility without prior surgery for deep infiltrating endometriosis. Univariable analysis was used to identify determinant factors of pregnancy rate. CPR was calculated using cumulative-incidence methods from log-rank test and Kaplan-Meier curves. For multivariable analysis, Cox proportional hazards model was used. RESULTS: For CPR per patient analysis, the total number of cycles was 113 and the median number of cycles per patient was 1 (range: 1-3). In the whole population the CPR per patient after three ICSI-IVF cycles was 68.6%. The CPR for patients with or without associated adenomyosis was 19 and 82.4%, respectively (P= 0.01). In addition, a patient age over 35 years (P= 0.02) and anti-Mullerian hormone serum level under 2 ng/ml (P= 0.02) were associated with a decreased CPR per patient. At multivariable analysis, adenomyosis [HR = 0.34, 95% CI (0.12-0.99), P= 0.49] was associated with a decreased CPR. CONCLUSIONS: Our data confirm that ICSI-IVF offers a high CPR per patient. However, determinant factors of CPR should be taken into account when informing couples of their options. [less ▲]

Abstract Objective: Placenta increta or percreta is an uncommon pathology, sometimes associated with high maternal morbidity. Its prevalence increases proportionally to the number of cesarean sections. This study analyzed the changes of our management strategy to devise treatment guidelines for this uncommon disorder. Materials and methodology: Between 2005 and 2011, 10 cases of placenta increta or percreta were managed at our university hospital maternity department. Results: Among the 10 cases, seven were diagnosed prenatally. Two patients were diagnosed early, at 14 and 17 weeks of gestational age, and their pregnancies were terminated. Five had hysterectomies during the intrapartum period, and despite attempted conservative treatment for the two others, hysterectomy proved necessary 2 months postpartum because of intrauterine infections. Seven of the 10 women had hysterectomies. Conclusion: Prenatal diagnosis of placenta increta or percreta is essential to plan the delivery in a competent tertiary care center. The decision to perform a cesarean hysterectomy or leave the placenta in situ for spontaneous delivery is based on the extent of infiltration, the patient's hemodynamic status, and her desire to remain fertile. The high-risk of infection and severe hemorrhage must not be overlooked should conservative treatment be chosen. This situation requires prolonged close monitoring. [less ▲]

L’Insuffisance Ovarienne Prématurée (IOP) est une pathologie dont la présentation clinique est complexe. Elle survient chez 1% des femmes avant 40 ans, 0,1% avant 30 ans. Les causes sont multiples : les anomalies génétiques, les maladies auto-immunes, les atteintes ovariennes iatrogènes secondaires à la chirurgie, radiothérapie, chimiothérapie, aux facteurs environnementaux tels que les virus, les toxines, le tabac, et aux facteurs métaboliques. Cependant, dans la majorité des cas, l’étiologie de l’IOP est idiopathique. [less ▲]
