Self-care of vaginal pessary for pelvic organ prolapse: a systematic review and meta-analysis.

INTRODUCTION: There is no evidence about the efficacy of self-care of vaginal pessary in women with symptomatic pelvic organ prolapse (POP). The aim of this systematic review and meta-analysis is to assess the adherence to pessary treatment among women who engage in self-management of their pessary. METHODS: We performed a systematic review and meta-analysis, according to PRISMA 2020 guidelines, and selected seven publications for inclusion in the analysis. RESULTS: Pooled continuation rate of self-cared vaginal pessary was the 76% (95%CI: 66-85%) with a I2-test of 93.3% (p < 0.001). Pooled conversion to POP surgery was the 12% (95%CI: 1-23%) with a I2-test of 96% (p < 0.001). Continuation rate was not statistically different between women who were treated by self-care and non-self-care management of vaginal pessary (RR 1.11, 95%CI 0.96-1.27; p = 0.15), with a related I2-test of 37% (p = 0.21). CONCLUSION: Self-care vaginal pessary management presented a high continuation rate in women affected by pelvic organ prolapse at a long follow-up. The rate of conversion to surgical management of POP was low. No significant difference in continuation rate were highlighted between women who adopted the self-care or the clinical-based management of pessary.

Mobility analysis of a posterior sacrospinous fixation using a finite element model of the pelvic system.

INTRODUCTION AND HYPOTHESIS: In order to improve the knowledge POP physiopathology and POP repair, a generic biomechanical model of the female pelvic system has been developed. In the literature, no study has currently evaluated apical prolapse repair by posterior sacrospinous ligament fixation using a generic model nor a patient-specific model that personalize the management of POP and predict surgical outcomes based on the patient's pre-operative Magnetic Resonance Imaging. The aim of our study was to analyze the influence of a right and/or left sacrospinous ligament fixation and the distance between the anchorage area and the ischial spine on the pelvic organ mobility using a generic and a patient-specific Finite Element model (FEM) of the female pelvic system during posterior sacrospinous ligament fixation (SSF). METHODS: Firstly, we used a generic 3D FEM of the female pelvic system previously made by our team that allowed us to simulate the mobility of the pelvic system. To create a patient-specific 3D FEM of the female pelvic system, we used a preoperative dynamic pelvic MRI of a 68 years old woman with a symptomatic stage III apical prolapse and cystocele. With these 2 models, a SSF was simulated. A right and/or left SSF and different distances between the anchorage area and the ischial spine (1 cm, 2 cm and 3 cm.) were compared. Outcomes measures were the pelvic organ displacement using the pubococcygeal line during maximal strain: Ba point for the most posterior and inferior aspect of the bladder base, C point the cervix's or the vaginal apex and Bp point for the anterior aspect of the anorectal junction. RESULTS: Overall, pelvic organ mobility decreased regardless of surgical technique and model. According to the generic model, C point was displaced by 14.1 mm and 11.5 mm, Ba point by 12.7 mm, and 12 mm and Bp point by 10.6 mm and 9.9 mm after left and bilateral posterior SSF, respectively. C point was displaced by 15.4 mm and 11.6 mm and Ba point by 12.5 mm and 13.1mm when the suture on the sacrospinous ligament was performed at 1 cm and 3 cm from the ischial spine respectively (bilateral posterior SSF configuration). According to the patient-specific model, the displacement of Ba point could not be analyzed because of a significative and asymmetric organ displacement of the bladder. C point was displaced by 4.74 mm and 2.12 mm, and Bp point by 5.30 mm and 3.24 mm after left and bilateral posterior SSF respectively. C point was displaced by 4.80 mm and 4.85 mm and Bp point by 5.35 mm and 5.38 mm when the suture on the left sacrospinous ligament was performed at 1 cm and 3 cm from the ischial spine, respectively. CONCLUSION: According to the generic model from our study, the apex appeared to be less mobile in bilateral SSF. The anchorage area on the sacrospinous ligament seems to have little effect on the pelvic organ mobilities. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04551859.

Does surgery for colorectal endometriosis prior to IVF±ICSI have an impact on cumulative live birth rates?

RESEARCH QUESTION: Does colorectal endometriosis surgery prior to IVF ± intracytoplasmic sperm injection (ICSI) impact cumulative live birth rates? DESIGN: This retrospective, monocentric study (Lille University Hospital) was conducted between 1 January 2007 and 31 December 2018. Two groups of patients from the JFIV database were included: a group undergoing IVF±ICSI alone (120 patients, 215 oocyte retrievals), and a group undergoing surgery and then IVF±ICSI (69 patients, 109 oocyte retrievals). The mode of management was decided after a multidisciplinary team meeting. Different criteria such as age (cut-off 35 years), anti-Müllerian hormone concentration (cut off 2 ng/ml), imaging results and the patient's symptomatology were considered: the most symptomatic patients underwent surgery prior to IVF±ICSI. The cumulative clinical pregnancy and live birth rates obtained after four IVF attempts were estimated and compared between the two groups using competing risk survival methods. RESULTS: The cumulative live birth rates after four IVF attempts in the two groups were not statistically significantly different (50.8% in the IVF±ICSI group versus 52.2% in the surgery followed by IVF±ICSI group, P = 0.43). The results for the cumulative clinical pregnancy rates were the same (56.7% in the IVF±ICSI group versus 58% in the surgery followed by IVF±ICSI group, P = 0.47). CONCLUSION: The study shows that cumulative live birth and pregnancy rates were similar in infertile patients with colorectal endometriosis who underwent IVF±ICSI either with or without prior colorectal endometriosis surgery.

Pain assessment in women with or without endometriosis during the IVF process: a prospective study.

RESEARCH QUESTION: How does the typology and effect of pain vary between infertile patients with or without endometriosis during the different stages of the IVF process? DESIGN: A prospective, monocentric, observational cohort study was conducted at Lille University Hospital between November 2019 and June 2021. The study was proposed to all patients starting an IVF cycle. Pain assessment questionnaires using validated scales (about type of pain, without specific location), were completed by patients at key points during IVF: before starting treatment, at the end of stimulation and on the day of oocyte retrieval. RESULTS: A total of 278 patients were analysed: 73 patients with endometriosis and 205 without. At the start of the IVF process, patients with endometriosis had higher pain scores than disease-free women (mean numerical scale score 3.47 versus 1.12 [P < 0.0001]) and 17.81% of patients with endometriosis had neuropathic pain. For mental disorders before starting treatment, 22% of patients with endometriosis had suspected or confirmed depression, and 33% had anxiety compared with 8% and 20% in patients without endometriosis, respectively. During IVF, for patients without endometriosis, pain increased significantly between the baseline, the end of stimulation and on the day of retrieval (P ≤ 0.05). In patients with endometriosis, however, pain did not significantly vary during these times. CONCLUSION: Endometriosis is associated with higher pain scores, but no increase in pain was observed during IVF for these patients. It seems essential to screen and characterize pain phenotypes in all patients before starting treatment and during stimulation to improve pain management.

Comparing vNOTES Hysterectomy with Laparoscopic Hysterectomy for Large Uteri.

STUDY OBJECTIVE: Our study aimed to compare conventional laparoscopic hysterectomies (LHs) with vaginal natural orifice transluminal endoscopic surgery (vNOTES) hysterectomies performed for patients with large uteri (weight >280 g) at our institution, which underwent a change in practice from conventional LH to vNOTES for large uteri. DESIGN: Retrospective cohort. SETTING: French tertiary university hospital. PATIENTS: Two cohorts: the last 54 patients who underwent vNOTES hysterectomy and the last 52 patients who underwent conventional LH for large uteri. INTERVENTION: Baseline characteristics and surgical outcomes were assessed, including uterine weight, mode of delivery for previous pregnancies, history of abdominal surgery, indication for hysterectomy, associated procedures, operative time (OT), complications, volume of intraoperative bleeding, and length of postoperative hospital stay. MEASUREMENTS AND MAIN RESULTS: Both groups were comparable, with a mean uterine weight of 586.4 ± 289.2 g in the laparoscopy group compared with 686.7 ± 374.6 g in the vNOTES group. There was a significant decrease in the OT in the vNOTES group with a median of 99 minutes (66.5-138.5 minutes) compared with 171 minutes (131-208 minutes) in the laparoscopy group, p <.001. The length of hospital stay was also decreased in the vNOTES group with a median of 0.5 nights compared with 2 nights in the laparoscopy group, p <.001. More patients were managed in an ambulatory setting in the vNOTES group (50% vs 3.7%, p <.001). Our study did not find any significant difference in terms of bleeding or the number of conversions to another surgical approach. The frequency of intraoperative and postoperative complications was very low. CONCLUSION: Compared with the laparoscopic approach, vNOTES hysterectomy for large uteri (>280 g) is associated with decreased OT, a shorter hospital stay, and increased performance in the ambulatory setting.

Fast soft-tissue deformations coupled with mixed reality toward the next-generation childbirth training simulator.

High-quality gynecologist and midwife training is particularly relevant to limit medical complications and reduce maternal and fetal morbimortalities. Physical and virtual training simulators have been developed. However, physical simulators offer a simplified model and limited visualization of the childbirth process, while virtual simulators still lack a realistic interactive system and are generally limited to imposed predefined gestures. Objective performance assessment based on the simulation numerical outcomes is still not at hand. In the present work, we developed a virtual childbirth simulator based on the Mixed-Reality (MR) technology coupled with HyperMSM (Hyperelastic Mass-Spring Model) formulation for real-time soft-tissue deformations, providing intuitive user interaction with the virtual physical model and a quantitative assessment to enhance the trainee's gestures. Microsoft HoloLens 2 was used and the MR simulator was developed including a complete holographic obstetric model. A maternal pelvis system model of a pregnant woman (including the pelvis bone, the pelvic floor muscles, the birth canal, the uterus, and the fetus) was generated, and HyperMSM formulation was applied to simulate the soft tissue deformations. To induce realistic reactions to free gestures, the virtual replicas of the user's detected hands were introduced into the physical simulation and were associated with a contact model between the hands and the HyperMSM models. The gesture of pulling any part of the virtual models with two hands was also implemented. Two labor scenarios were implemented within the MR childbirth simulator: physiological labor and forceps-assisted labor. A scoring system for the performance assessment was included based on real-time biofeedback. As results, our developed MR simulation application was developed in real-time with a refresh rate of 30-50 FPS on the HoloLens device. HyperMSM model was validated using FE outcomes: high correlation coefficients of [0.97-0.99] and weighted root mean square relative errors of 9.8% and 8.3% were obtained for the soft tissue displacement and energy density respectively. Experimental tests showed that the implemented free-user interaction system allows to apply the correct maneuvers (in particular the "Viennese" maneuvers) during the labor process, and is capable to induce a truthful reaction of the model. Obtained results confirm also the possibility of using our simulation's outcomes to objectively evaluate the trainee's performance with a reduction of 39% for the perineal strain energy density and 5.6 mm for the vertical vaginal diameter when the "Viennese" technique is applied. This present study provides, for the first time, an interactive childbirth simulator with an MR immersive experience with direct free-hand interaction, real-time soft-tissue deformation feedback, and an objective performance assessment based on numerical outcomes. This offers a new perspective for enhancing next-generation training-based obstetric teaching. The used models of the maternal pelvic system and the fetus will be enhanced, and more delivery scenarios (e.g. instrumental delivery, breech delivery, shoulder dystocia) will be designed and integrated. The third stage of labor will be also investigated to include the delivery of the placenta, and the clamping and cutting of the umbilical cord.

Association between endometriosis, infertility and autoimmune antiplatelet glycoprotein VI antibodies in two patients.

The association between endometriosis and autoimmune diseases is well known, however no acquired platelet function defect has been described so far. We describe the case of two patients with endometriosis associated with an antiplatelet glycoprotein VI (anti-GPVI) antibody. The two women with deep pelvic endometriosis associated with secondary infertility presented a mild bleeding tendency, a deficient platelet aggregation response to collagen, convulxin or CRP and a severe GPVI deficiency. Immunoblot revealed a combined FcRγ deficiency but no indication of GPVI cleavage. In the first case, platelet count was normal and an anti-GPVI IgG was detected in plasma. A first corticosteroids administration normalized in vitro platelet functions but further administrations were unsuccessful. Three IVF attempts failed. Conservative laparoscopic surgery was carried out after antifibrinolytic treatment without bleeding. The second case presented with a history of moderate thrombocytopenia and a weak anti-GPVI in the context of infertility and autoimmune disease, the Sjögren syndrome resolved after corticosteroids and hydroxychloroquine treatment. Acquired GPVI deficiencies are rare. It would be useful to determine whether the association with endometriosis is coincidental or not by more systematic investigations. It does not seem that in these patients, GPVI deficiency is associated with an increased risk of bleeding.

What is the context? • Evidence for an immune system dysfunction is reported in endometriosis and the association between endometriosis and autoimmune diseases is well known.• No autoimmune platelet function defect has been described so far.What is new?• We report two unrelated patients with endometriosis-associated infertility presenting a platelet glycoprotein VI deficiency due to an autoantibody.• In both cases, a deficient platelet aggregation response to collagen, convulxin or CRP and a severe GPVI deficiency were observed.• Immunoblot revealed no indication of GPVI cleavage.What is the impact? • Our observation raises the question whether GPVI could be a preferential target for the development of anti-GPVI autoantibodies associated with endometriosis.• It does not seem that in these patients, GPVI deficiency is associated with an increased risk of severe bleeding disorder.

vNOTES Hysterectomy: What about Obese Patients?

STUDY OBJECTIVE: To compare the surgical outcomes of hysterectomy by vaginal natural orifice transluminal endoscopic surgery (vNOTES) for patients with body mass index (BMI) <30 and BMI ≥30. DESIGN: A retrospective cohort study. SETTING: A French teaching hospital. PATIENTS: All patients who underwent a vNOTES hysterectomy from February 2020 to January 2022 were included (N = 200). The vNOTES approach was chosen for all patients requiring a hysterectomy, unless the procedure was for endometriosis or cancer (except grade 1 endometrioid adenocarcinoma). INTERVENTIONS: Patients were categorized into 2 groups based on their BMI (<30 or ≥30 kg/m2). The population characteristics, surgical outcomes, and hospitalization outcomes were compared. The main outcome was the intraoperative conversion rate. Secondary end points were blood loss, operative time, perioperative and postoperative complications, and same-day surgery management. MEASUREMENTS AND MAIN RESULTS: A total of 146 patients were included in the BMI <30 group, and 54 patients in the BMI ≥30 group. There was no statistical difference between obese and nonobese patients concerning intraoperative conversion (p = .150), with 4 cases occurring in the BMI <30 group (2.74%) and 4 occurring in the BMI ≥30 group (7.41%). Operative times were longer in obese patients (115.93 min [±55.28] vs 79.78 min [±40.38], p <.001). There was no significant difference in blood loss (p = .337) or perioperative and postoperative complications (p = .346 and p = .612, respectively). The ability to complete the surgery as a same-day procedure was no different between obese and nonobese patients (p = .150). CONCLUSION: The results concerning intraoperative conversion and perioperative and postoperative complications show that vNOTES hysterectomies seem to be feasible for obese patients. When same-day surgery was decided before surgery, no more obese than nonobese patients were converted to conventional hospitalization. Further studies are needed to confirm these observations.

Long-Term Assessment of Pelvic Organ Prolapse Reoperation Risk in Obese Women: Vaginal and Laparoscopic Approaches.

The aim of this study was to compare reoperation risks after pelvic organ prolapse repair at 5-year follow-up between obese, overweight, and normal-weight women and to assess these risks accounting for the surgical procedure. We performed a retrospective chart review of all the women who underwent POP repair by transvaginal mesh surgery between January 2005 and January 2009 or laparoscopic sacrocolpopexy between January 2003 and December 2013 at the Gynecologic Surgery Department of the Lille University Hospital. During the study period, 744 women who underwent POP repair were divided into three groups: 382 (51%), 240 (32%), and 122 (16%) in the nonobese group (BMI < 25 kg/m²), overweight group (25 kg/m² ≤ BMI < 30 kg/m²), and obese group (BMI ≥ 30 kg/m²), respectively. The primary outcome was global reoperation. The median duration of follow-up was 87 months. The risks of global reoperation did not significantly differ between the three BMI groups (adjusted HR (95% CI): 1.12 (0.69 to 1.82) for overweight women and 0.90 (0.46 to 1.74) for obese women compared to normal-weight women, adjusted p = 0.80), nor among the women who underwent transvaginal mesh surgery or laparoscopic sacrocolpopexy. The risks of reoperation for POP recurrence, stress urinary incontinence, or mesh-related complications did not significantly differ between the three BMI groups in the overall population nor accounting for the surgical procedure. In conclusion, obesity does not seem to be a risk factor of reoperation for POP recurrence, SUI, or mesh-related complications in the long term regardless of the surgical approach.

Long-Term Outcomes after Pelvic Organ Prolapse Repair in Young Women.

The aim of the study was to describe the long-term outcomes of Pelvis Organ Prolapse (POP) repair in women under 40 years old. A retrospective chart review of all POP repairs performed in women ≤40 years old between January 1997 and December 2015 in the Gynecologic Surgery Department of Lille University Hospital was performed. Inclusion criteria were all women ≤40 years old who underwent a POP repair with a stage ≥2 POP according to the Baden and Walker classification. The study population was separated into three groups: a sacrohysteropexy group, a vaginal native tissue repair (NTR) group, and a transvaginal mesh surgery (VMS) group. The primary outcome was reoperation procedures for a symptomatic recurrent POP. Secondary outcomes were other complications. During the study period, 43 women ≤ 40 years old who underwent a POP repair were included and separated into three groups: 28 patients (68%), 8 patients (19%), and 7 patients (16%) in the sacrohysteropexy, VMS, and NTR groups respectively. The mean followup time was 83 ± 52 months. POP recurrence, reoperated or not, was essentially diagnosed in the VMS group (87.5%) and the NTR group (50%). POP recurrence repairs were performed for nine patients (21%): 7%, 62.5%, and 25% in the sacrohysteropexy, VMS, and NTR groups, respectively. Global reoperation concerned 10 patients (23%) whatever the type of POP surgery, mainly patients from the VMS group (75%) and from the NTR group (25%). It occurred in only 7% of patients from the sacrohysteropexy group. Two patients (4%) presented a vaginal exposure of the mesh (in the VMS group). De novo stress urinary incontinence was encountered by nine patients (21%): 29% and 12.5% in the sacrohysteropexy and NTR groups, respectively. Despite the risk of recurrence, POP repair should be proposed to young women in order to restore their quality of life. Vaginal native tissue repair or sacrohysteropexy should be performed after explaining to women the advantages and disadvantages of each procedure.

Risk factors for immediate failure of outpatient surgery in gynecologic surgery.

OBJECTIVE: To describe the risk factors for immediate failure of gynecologic outpatient surgery. The secondary objective was to describe the risk factors for rehospitalization within 30 days after surgery. METHODS: This is a single-center retrospective cohort study conducted on all patients operated on in outpatient surgery in gynecology at the Lille University Hospital. The primary outcome was defined as any unanticipated admission to the inpatient postoperative care unit on the day of the operation. The secondary outcome was defined as any rehospitalization within 30 days following the intervention. Our statistical analysis included 916 patients operated on between January and July 2019. RESULTS: In our study, 84 patients (9.2%) had an immediate failure of outpatient surgery. The most frequent etiologies were surgical (58.3%). In multivariate analysis with logistic regression, the following variables were associated with an increased risk of immediate failure of outpatient surgery: urogynecologic surgery (P < 0.001), complex laparoscopy (P = 0.004), endometriosis surgery (P < 0.001), and a duration of intervention longer than 1 hour (P < 0.001). CONCLUSION: We find an increased risk of immediate failure of gynecologic outpatient surgery depending on the type of surgery as well as for surgeries lasting more than 1 hour.

Is V-NOTES Hysterectomy as Safe and Feasible as Outpatient Surgery Compared with Vaginal Hysterectomy?

STUDY OBJECTIVE: The vaginal approach is the reference surgical route to perform hysterectomy for benign pathologies. Hysterectomy via transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) is a new technique that would overcome the limitations of vaginal surgery by allowing a complete exploration of the peritoneal cavity and a constant visual control of the adjacent structures. The aim of this study is to assess the V-NOTES technique compared with vaginal hysterectomy (VH). DESIGN: A retrospective cohort study. SETTING: French teaching hospital. PATIENTS: The first 50 V-NOTES hysterectomies were included successively and compared with the last 50 VH performed from March 2019 to November 2020. The study concerned all patients requiring hysterectomy unless it was for endometriosis or cancer (except for grade 1 endometrioid adenocarcinoma). INTERVENTIONS: The baseline characteristics and the surgical outcomes were compared. The main outcome assessed was the performing of outpatient surgery. Secondary end points were uterine weight and intraoperative and postoperative complications. MEASUREMENTS AND MAIN RESULTS: The rate of outpatient surgery did not differ between the 2 surgical techniques (p = .23). The success rate of outpatient management was 77% in the V-NOTES group versus 75% in the VH group (p = .85). There was no difference in surgical outcomes between the 2 groups, except for the rate of salpingectomies or adnexectomies, which was significantly higher in the V-NOTES group, with 100% of patients undergoing one of these procedures, compared with 60% of patients in the vaginal route group (p < .001). There were 2 cases of re-admission in the month following the intervention in the vaginal group and 0 cases in the V-NOTES group. CONCLUSION: Hysterectomy by V-NOTES can be performed as a safe and adequate alternative to VH. This surgical route is a good candidate for outpatient management. However, more studies need to be conducted to confirm these findings.

Evaluation of the contribution of a multimedia tool in the monitoring of low-risk pregnancy: Qualitative study carried out with general practitioners in France.

OBJECTIVE: We aimed to evaluate the usefulness of a new multimedia tool, a video on pregnancy and a video on physiological labor, for the initial and continuous training of general practitioners and the education of pregnant women. METHOD: This is a qualitative study for which we conducted semi-structured individual interviews with general practitioners in France practicing pregnancy monitoring. The interviews were recorded and then transcribed verbatim. Data triangulation and thematic analysis were carried out. RESULTS: Twelve interviews were carried out between November 2018 and September 2019. Physicians agreed on the complexity of obstetrics and the need for continuous training. From this perspective, the video tool was found to be useful for initial training and continuing medical education. Our video was regarded as useful for reassuring doctors regarding their knowledge and practice. Women's knowledge of pregnancy has been found to be insufficient, and this tool has real potential to overcome this lack of knowledge. Areas for improvement and the method of dissemination were also discussed. CONCLUSION: In the multimedia era, our tool has real potential for the initial and continuing training of doctors and the education of patients. It would be useful in the future to evaluate our multimedia tool with patients.

Cystic adenomyoma surgery.

OBJECTIVE: Cystic adenomyoma is a lesion located within the myometrium. It is lined with endometrium and has hemorrhagic content. This rare entity has been described as a focal form of adenomyosis. However, it is poorly understood, and the management of symptomatic patients is not codified. Our objective is to evaluate the effectiveness of treatment with planned surgery for cystic adenomyoma on symptoms and fertility in a retrospective series of patients. STUDY DESIGN: This is a retrospective study between January 2011 and January 2018 in a university hospital of patients that had surgery for cystic adenomyoma with uterine preservation. RESULTS: Pre-operative, per-operative, and post-operative data were recorded. Of the 18 patients included, 3 were lost to follow-up; 15 underwent laparoscopic surgery and 3 operative hysteroscopies. Complications during and after surgery were rare, involving only 3 patients, and of low severity. One patient saw no improvement in pain after surgery and 2 patients saw only partial improvement in their pain; 7 patients achieved at least one pregnancy with favorable outcome after surgery. CONCLUSION: Based on this series, we argue that conservative surgical treatment for cystic adenomyoma generally improves pain and fertility without causing morbidity.

Impact of endometriosis on oocyte morphology in IVF-ICSI: retrospective study of a cohort of more than 6000 mature oocytes.

BACKGROUND: Infertility associated with endometriosis can be explained by several non-exclusive mechanisms. The oocyte plays a crucial role in determining embryonic competence and this is particularly relevant for in vitro fertilization (IVF) outcomes. According to some authors, the morphology of oocytes could also be a non-invasive marker of oocyte quality. The aim of this study was to evaluate the relationship between endometriosis and oocyte morphology after controlled ovarian stimulation for intracytoplasmic sperm injection (ICSI) on a large oocyte cohort. METHODS: Single-center comparative retrospective study in the academic In Vitro Fertilization (IVF) unit of the Lille University Hospital. A total of 596 women treated for IVF-ICSI with ejaculated spermatozoa for sperm alterations were included. They were classified as endometriosis (n = 175) or control groups (n = 401). The morphological evaluation of 2,016 mature oocytes from 348 cycles of patients with endometriosis was compared with that of 4,073 mature oocytes from 576 control cycles. The main outcome measures were Average Oocyte Quality Index (AOQI) and metaphase II oocyte morphological scoring system (MOMS). Comparison of groups was carried out by a mixed linear model and by a generalized estimation equation model with a "patient" random effect to consider that a patient might have several attempts. RESULTS: No difference in AOQI and MOMS scores was found between endometriosis and control women (adjusted p = 0.084 and 0.053, respectively). In case of endometriosis, there were significantly fewer metaphase II oocytes retrieved, embryos obtained, grade 1 embryos and number of cumulative clinical pregnancies compared to controls. In the endometriosis group, endometriosis surgery was associated with a reduced number of mature oocytes retrieved, and the presence of endometrioma(s) was associated with some abnormal oocyte shapes. Nevertheless, no difference concerning the AOQI and MOMS scores was found in these subgroups. CONCLUSION: Endometriosis does not have a negative impact on oocytes' morphology in IVF-ICSI. TRIAL REGISTRATION: On December 16, 2019, the Institutional Review Board of the Lille University Hospital gave unrestricted approval for the anonymous use of all patients' clinical, hormonal and ultrasound records (reference DEC20150715-0002).

Oocyte accumulation for fertility preservation in women with benign ovarian tumours with a history of previous surgery, multiple or large cysts.

RESEARCH QUESTION: What are ovarian stimulation cycle outcomes and acceptance rates of an oocyte accumulation programme in young women with benign ovarian tumour (BOT)? DESIGN: Retrospective cohort study conducted at the Academic Assisted Reproductive Technology and Fertility Preservation Centre, Lille University Hospital, between January 2016 and December 2019. The number of metaphase II oocytes per cycle and per patient after accumulation were evaluated. Two groups were identified for the analysis: endometrioma ('endometrioma') and dermoid, mucinous or serous cyst ('other cysts'). RESULTS: A total of 113 fertility-preservation cycles were analysed in 70 women aged 27.9 ± 4.8 years. Almost all women had undergone previous ovarian surgery before fertility preservation (89%). Mean anti-Müllerian hormone levels before ovarian stimulation was 12.5 ± 8.7 pmol/l. A total of 6.4 ± 3.4 oocytes were retrieved, and 4.3 ± 3.4 metaphase II (MII) oocytes were vitrified per cycle. All agreed to the oocyte accumulation programme and all underwent at least one cycle. To date, 36 (51%) patients achieved two or three fertility- preservation cycles. After accumulation, 7.0 ± 5.23 MII oocytes were vitrified per patient. No difference was found in ovarian response and oocyte cohort between the 'endometrioma' and 'other cysts' groups. Questionnaires completed after oocyte retrieval revealed abdominal bloating and pelvic pain in most patients, with no difference according to the type of cyst. No serious adverse events occurred. CONCLUSIONS: Oocyte accumulation should be systematically offered to young women with BOT irrespective of histological type, as it seems to be well-tolerated. Long-term follow-up is needed to assess the efficiency of oocyte accumulation to optimize the chances of subsequent pregnancies.

Pelvic organ prolapse meshes: Can they preserve the physiological behavior?

Implants for the cure of female genital prolapse still show numerous complications cases that sometimes have dramatic consequences. These implants must be improved to provide physiological support and restore the normal functionalities of the pelvic area. Besides the trend towards lighter meshes, a better understanding of the in vivo role and impact of the mesh implantation is required. This work investigates the mechanical impact of meshes after implantation with regards to the behavior of the native tissues. Three meshes were studied to assess their mechanical and biological impact on the native tissues. An animal study was conducted on rats. Four groups (n = 17/group) underwent surgery. Rats were implanted on the abdominal wall with one of the three polypropylene knitted mesh (one mesh/group). The last group served as control and underwent the same surgery without any mesh implantation. Post-operative complications, contraction, mechanical rigidities, and residual deformation after cyclic loading were collected. Non-parametric statistical comparisons were performed (Kruskal-Wallis) to observe potential differences between implanted and control groups. Mechanical characterization showed that one of the three meshes did not alter the mechanical behavior of the native tissues. On the contrary, the two others drastically increased the rigidities and were also associated with clinical complications. All of the meshes seem to reduce the geometrical lengthening of the biological tissues that comes with repetitive loads. Mechanical aspects might play a key role in the compatibility of the mesh in vivo. One of the three materials that were implanted during an animal study seems to provide better support and adapt more properly to the physiological behavior of the native tissues.

Predictive value of 4th post-operative-day CRP in the early detection of complications after laparoscopic bowel resection for endometriosis.

OBJECTIVE: Post-operative CRP on postoperative day 4 (POD) is used for the early detection of complications after colorectal surgery for cancer, but there is no evidence yet that justifies the use of this marker for bowel resection in case of endometriosis. STUDY DESIGN: We retrospectively included 66 consecutive patients who underwent bowel resection for endometriosis (stage 4) in Lille university hospital, France, from August 1, 2015 until January 31, 2017. The composite endpoint of our study included anastomotic leakages, infectious or thrombo-embolic complications, hematomas, bowel stenosis, rectorrhagia, voiding dysfunction, and rehospitalization for related symptoms. RESULTS: CRP on POD 4 presents a satisfying area under the curve of 0.85, for the composite endpoint. A CRP cut off value of 56 mg/L yielded a sensitivity of 0.61 (IC95%: 0.36 to 0.83) and a specificity of 0.98 (IC95%: 0.89 to 1). The negative and positive predictive values were 0.87 and 0.92. CONCLUSION: The negative predictive value of the CRP on POD 4 after bowel resection for endometriosis is a useful early indicator for detecting a complication. Therefore, this biomarker might be safely used as an additional criterion for a safe discharge from hospital after colorectal resection in endometriosis.

Surgical training through simulation dedicated to French Ob-gyn residents. Evaluation and satisfaction.

OBJECTIVE: In order to be able to develop surgical training of residents through simulation, we carried out a descriptive study, evaluating the satisfaction of participating residents and the benefit of the workshops offered during the 4 th Junior Master Class, free annual training organized in 2017 in Lille University Hospital. It is dedicated to ob-gyn residents in France, overseas departments and territories. MATERIAL AND METHODS: During two days, plenary sessions and practical workshops on animal models or simulators were organized in laparoscopy, diagnostic and operative hysteroscopy, vaginal surgery and robotic surgery. A questionnaire was given anonymously to each student, collecting on the one hand their surgical curriculum, on the other hand, the evaluations of the theoretical contribution and the quality of the interventions and materials offered during the plenary sessions. The last part was subdivided into a questionnaire specific to each workshop. RESULTS: The 48 residents who voluntarily followed this training were overwhelmingly satisfied with the quality of the training offered. The practical benefits outweighed the theoretical benefits. These workshops improved their practical skills from 63 % to 84 % depending on the workshops offered. In addition, 100 % of students would recommend this training to other residents and consider it useful for their future practice. CONCLUSION: These very satisfactory results encourage us to organize new surgical training. Simulation is the key point for an appropriate surgical learning.

Pelvic endometriosis: Refer to the surgeon at the right moment: Pelvic endometriosis: When refer to the surgeon?

BACKGROUND: As endometriosis is not a single condition but different morphological types, it is easy to conceive that its management allow for a diversity of approaches. The objective of this literature review is about a simplified pathway through care for patients with endometriosis, and to target the right time for surgical treatment. METHODS: Through a literature and references review, the different surgical care arrangements according to attainment, to symptoms and to the patients demands and expectations are reviewed. RESULTS: An existing literature and recommendations synthesis has been done, and it was found that an optimum medical or surgical care rely on a multidisciplinary approach. Asymptomatic patients should not have surgery, and the medical treatment precede surgical treatment in numerous indications. In case of a surgical need, the right moment is determined by the recommendations, as noted in this article. Different aspects are necessary, the symptomatology, the intend to be pregnant and the recurrence of lesions in particular, but also the use of medically assisted reproduction or not. CONCLUSION: In order to optimize the surgical treatment of patients with endometriosis, it is advisable to not refer these patients to the surgeon not too soon and not too late, furthermore if he's an expert. In all cases the treatment is multidisciplinary, and the most difficult cases are referred to multidisciplinary consultative reunion. The surgical treatment relies on "centre of expertise's" existence for some specific forms of deep endometriosis. The surgical treatment is a question of both pathology and timing. BRIEF SUMMARY: In order to optimize the surgical treatment of endometriosis, it is advisable to refer patients to the surgeon at the right moment.
