MRI and rectal endoscopy sonography performance to diagnose the digestive depth infiltration of pelvic endometriosis.

INTRODUCTION: The main objective of this study was to evaluate the performances of MRI and rectal endoscopy sonography (RES) in predicting the depth of bowel wall infiltration by deep infiltrating endometriosis (DIE). MATERIAL AND METHOD: We conducted a single center retrospective study from April 2014 to March 2020 including all patients who had undergone digestive tract resection (discoid or segmental) for DIE removal and who had benefited from full preoperative imaging workup based on both pelvic MRI and RES. RESULTS: Fifty two patients were enrolled in the study. Median age was 35.8 years (26.1-44.5 years). Indications for surgery mainly comprised chronic pelvic pain (94.2%) and infertility (36.5%). Overall, pathological examination showed digestive involvement in 92.3% of patients, while transmural infiltration was found in 38.4% of cases. In contrast, both MRI and RES suspected transmural involvement in 42 patients (80.8%). Corresponding sensitivity and specificity were 0.95 [95% CI (0.751-0.999)] and 0.28 [95% CI (0.137-0.467)], respectively. Our results revealed agreement between MRI and RES in 85% of cases with a kappa at 0.5 [95% CI (0.207-0.803), moderate agreement]. Subgroup analysis in patients with transmural MRI lesions showed a sensitivity of 0.95 [95% CI (0.740-0.999)] and a specificity of 0.13 [95% CI (0.028-0.336)]. CONCLUSION: Our study suggests that performing a second-line examination is not useful if there is no transmural impairment in MRI or RES. Nevertheless, the combination of these two preoperative examinations seems to be essential for the evaluation of the depth of digestive involvement of endometriosis to guide surgical management as effectively as possible. The constitution and training of multidisciplinary expert groups must be developed to be able to offer optimal patient management.

Study of postoperative complications after the implementation of a multidisciplinary care pathway for patients with digestive endometriosis.

PURPOSE: To assess the quality of care following the establishment of a multidisciplinary care pathway for patient operated on for deep pelvic endometriosis with digestive impairment. METHODS: We conducted a retrospective monocentric study of patients suffering from deep infiltrating endometriosis, treated in Gynaecological Department at Toulouse University Hospital from January 2018 to December 2020. We compared our results to those of our previous study, Gornes et al. which showed a postoperative complication occurred in 37.8% of the cases and a postoperative severe complication according to the Clavien-Dindo classification (grades 3b) rate of 18.3%. RESULTS: 98 patients were included. Our study shows a clear decrease in postoperative complications with an overall complication rate of 19.4% and severe complications (grades 3b) of 4.1%. The rate of complication appeared to be significantly less frequent in the case of shaving in relation to other digestive procedures (p = 0.008) and in the case of a lesion of < 20 mm by MRI (p = 0.01). The use of multidisciplinary surgical care was more frequent in the case of multiple locations (66.7% vs. 41.8%, p = 0.07) and was more frequent in the case of transmural damage with echo endoscopy (and to a lesser degree in the case of damage of the muscularis or mucous membrane) (p = 0.05). CONCLUSIONS: Multidisciplinary care of endometriosis with digestive damage appears to be indispensable. The intraoperative intervention of a skilled digestive surgeon of bowel endometriosis helps create the best balance between effectiveness-complications-functional prognosis, with a reduction of severe postoperative complications.

Aspirin for prevention of preeclampsia and fetal growth restriction.

For the past decades, growing attention has been given to aspirin use during pregnancy. It favors placentation by its proangiogenic, antithrombotic, and anti-inflammatory effects. Therefore, low doses of aspirin are prescribed in the prevention of placenta-mediated complications, mainly preeclampsia and fetal growth restriction. However, questions regarding its clinical application are still debated. Aspirin is effective in preventing preeclampsia in a high-risk population. Most guidelines recommend that risk stratification should rely on medical history. Nevertheless, screening performances dramatically improve if biochemical and biophysical markers are included. Concerning the appropriate timing and dose, latest studies suggest aspirin should be started before 16 weeks of pregnancy and at a daily dose of 100 mg or more. Further studies are needed to improve the identification of patients likely to benefit from prophylactic aspirin. Besides, the role of aspirin in the prevention of fetal growth restriction is still questioned.

Perioperative outcomes using LigaSure compared with conventional technique in peripartum hysterectomy.

OBJECTIVE: To evaluate the use of new bipolar vessel sealing system like LigaSure™ compared to the standard surgical technique (suture) during emergency peripartum hysterectomy (EPH). METHODS: A retrospective observational bicentric study was conducted from February 2005 to August 2018 in the maternity wards of the University Hospital of Toulouse and Angers. All EPHs performed up to 24 h after delivery were included. The main outcome was the total blood loss. Secondary outcomes were operating time, number of blood transfusions, per and postoperative complications. A subgroup analysis was performed between hysterectomies performed in emergency and scheduled hysterectomies. RESULTS: Among 111,266 deliveries, 86 women (0.07%) underwent EPH, 29 were operated upon with LigaSure™, 57 with the traditional technique. In the LigaSure™ arm, there were statistically lower blood loss (3198 mL vs 4223 mL, p = 0.02), fewer blood transfusions (62.1% vs 94.7%, p = 0.0003, confirmed in subgroup analysis), and fewer perioperative complications (8.3% vs 45.5%, p = 0.04) for scheduled hysterectomies. CONCLUSION: Bipolar vessel sealing systems such as LigaSure™ are a surgical instrument, easy to use for the surgeon, with an interest in the management of EPH, particularly for total blood loss, transfusions, and intraoperative complications.

Hepatic pedicle endometriosis: Case report and review of the literature.

The localization of endometriotic disease in the hepatic pedicle has never been reported to date. We report the first case of a 67-year-old postmenopausal patient having presented an endometriotic lesion in the hepatic pedicle. A surgical biopsy was needed to confirm the diagnosis after a first radiologic biopsy that concluded the presence of a mucinous cystic tumor with low-grade dysplasia. Medical treatment with aromatase inhibitors was carried out because of the inextirpable nature of the lesion. The diagnosis and therapeutic management of this rarely occurring lesion of atypical localization in a postmenopausal patient is presented here. A review of the literature on this localization could have led to a damaging surgical treatment due to the different diagnoses suggested. Management of endometriosis relies on a multidisciplinary approach that each practitioner must know how to broach with patients of all ages.

Spatulas for entrapment of the after-coming head during vaginal breech delivery.

PURPOSE: To evaluate spatulas for entrapment of the after-coming head (EAH) during vaginal breech delivery, in the setting of failed usual manoeuvres (Bracht or Mauriceau). METHODS: We led a retrospective cohort study in two tertiary referral hospital in France. From 2003 to 2018, we included all deliveries of live children requiring the use of spatulas (Thierry's and Teissier's) for EAH during vaginal breech delivery. RESULTS: Over the period, 59 breech deliveries with spatulas for EAH were enrolled (prevalence 2.3%). No vaginal delivery failures were found. The average term was 36 weeks of gestation. Mean maternal age was 29.4 years and median parity was 1. 50.8% of the foetuses presented as complete breech, 40.7% as frank breech, and 8.5% as footling breech. Maternal morbidity was low: no obstetrical lesions of the anal sphincter, 28% episiotomy (performed before application of instruments in most cases). There was no evidence of foetal over-morbidity. The average weight of the foetuses was 2635g. There was no serious trauma associated with the use of spatulas: only one case of skin lesion and a case of non-severe cephalhematoma could be attributed to the instrument. Mean arterial pH was 7.19, the median 5-min Apgar score was 10. CONCLUSION: In compliance with obstetrical mechanics, spatulas should be considered as an effective instrument during EAH with maternal and foetal safety. This is the first cohort describing the use of an instrument to manage EAH during vaginal breech delivery, while knowledge and mastery of this technique are essential to manage this situation.

Can early ßhCG change and baseline progesterone level predict treatment outcome in patients receiving single dose Methotrexate protocol for tubal ectopic pregnancy?

INTRODUCTION: We aimed to assess the prognostic significance of early ßhCG change and baseline progesterone level on treatment outcome among women receiving single dose Methotrexate protocol for tubal ectopic pregnancy (EP). MATERIAL AND METHODS: Retrospective study involving all consecutive patients diagnosed with EP and receiving Methotrexate therapy form January 2015 to December 2016. Patients were stratified into 2 groups according to treatment outcome: success group (n = 66) involved women who displayed complete resolution of serum ßhCG levels following a single course of Methotrexate; failure group (n = 55) included patients who required repeated Methotrexate administration and/or surgical management. Predictive performances of baseline progesterone and ratio"ßhCG level on day 4/ ßhCG level on day 1″ (d4/d1) on treatment outcome were assessed using Receiving Operating Characteristics curves. RESULTS: The ratio d4/d1 displayed good performances in predicting treatment outcome (AUC = 0.826). A ratio ≤ 0.7 was associated with a success rate of 94% after 1 course of Methotrexate and 100% after 2 courses. In contrast, a ratio >1.7 was associated with a failure rate of 100%. Conversely, baseline progesterone showed poor performances (AUC = 0.611). CONCLUSIONS: Patients with extreme ßhCG changes (n = 33) on day 4 might benefit from a more personalized approach: simplified monitoring in those with a decline ≥30%, anticipated second course of treatment in those with an increase > 70%.

Surgical peritoneal stress creates a pro-metastatic niche promoting resistance to apoptosis via IL-8.

BACKGROUND: The mainstay of treatment of advanced ovarian cancer (AOC) involves chemotherapy, and debulking surgery. However, despite optimal surgical procedure and adjuvant chemotherapy, 60% of patients with AOC will relapse within 5 years. Most recurrences occur in the peritoneal cavity, suggesting the existence of occult sanctuaries where ovarian cancer cells (OCC) are protected. In murine models, surgical stress favors tumor growth; however, it has never been established that surgery may affect OCC sensitivity to subsequent chemotherapy. In this study, we investigated how the surgical stress could affect the chemosensitivity of OCC. METHODS: To avoid bias due to tumor burden in peritoneal cavity and duration of surgery, we used peritoneal biopsies from patients without a malignancy at precise time points. During laparotomies, peritoneal biopsies at the incision site were performed at the time of incision (H0 sample) and 1 h after initiation of surgery (H1 sample). We evaluated the chemoresistance to Taxol (0-20 µM) induced by H0 or H1 incubation (24 h) in two ovarian cancer cell lines OVCAR3 and SKOV3 and a primary cancer cell lines derived in our laboratory. RESULTS: Our results indicate that stressed peritoneum overexpressed cytokines, resulting in OCC increased resistance to therapy. Among these cytokines, IL8 was responsible for the resistance to apoptosis through the AKT pathway activation. Chemoresistance in OCC persists through the establishment of an autocrine IL8 loop. Finally, in a cohort of 32 patients, we showed an impact of IL8 tumoral overexpression on chemosensitivity and survival outcomes with a significant association to earlier recurrence. CONCLUSIONS: Our study demonstrated that precision surgery where targeted treatment would be used in combination with surgery is essential to obtain better tumor control.

Comparative mid-term anatomical and functional outcomes following laparoscopic sacrocolpopexy in women under and over 65: results from a prospective study.

PURPOSE: To compare mid-term anatomical and functional outcomes following laparoscopic sacrocolpopexy (LS) between women under and over 65. METHODS: Prospective and observational study involving patients with symptomatic pelvic organ prolapse (POP) undergoing LS. Study population was stratified according to patients' age at the time of surgery. POP symptoms and impact on quality of life were assessed by PFIQ-7 and PFDI-20 questionnaires at baseline and during follow-up. RESULTS: Among our study population (n = 72), 26 women were over 65 and 46 under 65. Mean follow-up duration was 17.6 months, and complete follow-up was available in 90% of patients. No differences between study groups were observed regarding surgery duration, length of stay, and peri-operative complications. Recurrence rate was 1.4% at 18 months of follow-up. Questionnaires analysis revealed a significant improvement in PFIQ-7 and PFDI-20 scores. We found no differences in post-operative scores between control and elderly groups. Sixteen patients experienced de novo stress urinary incontinence (22.2%), with no difference between groups (p = 0.7). Among them, seven required surgical management. CONCLUSIONS: LS was associated with high anatomical success rate and good functional outcomes, regardless of age at the time of surgery. LS should thus be considered in women over 65. Beyond age, the route of surgery should be driven by patient's choice and medical condition.

Operative vaginal delivery in case of persistent occiput posterior position after manual rotation failure: a 6-month follow-up on pelvic floor function.

PURPOSE: To compare the short- and long-term perineal consequences (at 6 months postpartum) and short-term neonatal consequences of instrumental rotation (IR) to those induced by assisted delivery (AD) in the occiput posterior (OP) position, in case of manual rotation failure. METHODS: A prospective observational cohort study; tertiary referral hospital including all women presenting with persistent OP position who delivered vaginally after manual rotation failure with attempted IR or AD in OP position from September 2015 to October 2016. Maternal and neonatal outcomes of all attempted IR deliveries were compared with OP operative vaginal deliveries. Main outcomes measured were pelvic floor function at 6 months postpartum including Wexner score for anal incontinence and ICIQ-FLUTS for urinary symptoms. Perineal morbidity comprised severe perineal tears, corresponding to third and fourth degree lacerations. Fetal morbidity parameters comprised low neonatal Apgar scores, acidaemia, major and minor fetal injuries and neonatal intensive care unit admissions. RESULTS: Among 5265 women, 495 presented with persistent OP positions (9.4%) and 111 delivered after manual rotation failure followed by AD delivery: 58 in the IR group and 53 in the AD in OP group. The incidence of anal sphincter injuries was significantly reduced after IR attempt (1.7% vs. 24.5%; p < 0.001) without increasing neonatal morbidity. At 6 months postpartum, AD in OP position was associated with higher rate of anal incontinence (30% vs. 5.5%, p = 0.001) and with more urinary symptoms, dyspareunia and perineal pain. CONCLUSIONS: OP operative deliveries are associated with significant perineal morbidity and pelvic floor dysfunction at 6 months postpartum.

Which Surgical Attitude to Choose in the Context of Non-Resectability of Ovarian Carcinomatosis: Beyond Gross Residual Disease Considerations.

BACKGROUND: In ovarian cancer, the increased rate of radical surgery comprising upper abdominal procedures has participated to improve overall survival (OS) in advanced stages by increasing the rate of complete cytoreductions. However, in the context of non-resectability, it is unclear whether radical surgery should be considered when it would lead to microscopic but visible disease (≤1 cm). We aimed to compare the survival outcomes among patients with incomplete cytoreduction according to the extent of surgery. METHODS: Overall, 148 patients presenting with advanced stage ovarian carcinomas were included in this retrospective study, regardless of treatment schedule. These patients were stratified according to the extent of surgery (standard or radical). Complete cytoreduction at the time of debulking surgery could not be carried out in all cases. RESULTS: Among our study population (n = 148), 96 patients underwent standard procedures (SPs) and 52 underwent radical surgeries (RP). Patients in the SP group had a lower Peritoneal Index Cancer (PCI) at baseline (12.6 vs. 14.9; p = 0.049). After PCI normalization, we observed similar OS in the SP and RP groups (39.7 vs. 43.1 months; p = 0.737), while patients in the SP group had a higher rate of residual disease >10 mm (p < 10(-3)). Patients in the RP group had an increased rate of relapse (p = 0.005) but no difference in disease-free survival compared with the SP group (22.2 for SP vs. 16.3 months; p = 0.333). Residual disease status did not impact survival outcomes. CONCLUSIONS: In the context of non-resectable, advanced stage ovarian cancer, standard surgery seems as beneficial as radical surgery regarding survival outcomes and should be considered to reduce surgery-associated morbidity.

Para-aortic workup in locally advanced cervical cancer: heterogeneity is still the rule. Results from a retrospective multicenter study.

PURPOSE: We retrospectively studied the different strategies of para-aortic (PA) staging of patients with PA involvement in locally advanced cervical cancer as conducted in eight centers in France and their impact upon survival and management. METHODS: All patients enrolled in this multicenter study presented with cervical cancer with PA involvement. The diagnosis of PA spread was based on imaging assessment of the PA area and/or pathological examination of harvested PA lymph nodes when staging lymphadenectomy was performed. Imaging modalities comprised positron emission tomography (PET), magnetic resonance imaging and/or computed tomography. Survival outcomes were evaluated retrospectively. RESULTS: One hundred and fifteen women were retrospectively studied. Radiological staging was conducted in 101 (87.8 %) patients. PET was performed in 66 patients (57.4 %). Its FN rate was 22.7 % (15/66) and its sensitivity 77.3 %. Para-aortic lymphadenectomy was conducted in a large proportion of patients (67.8 %). Its indications were not restricted to negative radiological workup. The lymphadenectomy rate was significantly higher in patients with earlier stages (p = 0.02) and lower tumor volume (p = 0.01). Treatment consisted of chemoradiation therapy with extended-field radiotherapy in all patients, followed by intracavitary brachytherapy in 94 cases (81.7 %) and completion surgery in 69 cases (60 %). Patients without para-aortic metastasis on radiological examination were more likely to receive all treatment modalities (p = 0.04). CONCLUSION: Despite established recommendations, our results point out the tremendous heterogeneity regarding para-aortic assessment. These differences in management are perhaps related to a recommended therapeutic strategy that does not appear to improve the poor prognosis associated with PA involvement.

SDF-1alpha concentration dependent modulation of RhoA and Rac1 modifies breast cancer and stromal cells interaction.

BACKGROUND: The interaction of SDF-1alpha with its receptor CXCR4 plays a role in the occurrence of distant metastasis in many solid tumors. This interaction increases migration from primary sites as well as homing at distant sites. METHODS: Here we investigated how SDF-1α could modulate both migration and adhesion of cancer cells through the modulation of RhoGTPases. RESULTS: We show that different concentrations of SDF-1α modulate the balance of adhesion and migration in cancer cells. Increased migration was obtained at 50 and 100 ng/ml of SDF-1α; however migration was reduced at 200 ng/ml. The adhesion between breast cancer cells and BMHC was significantly increased by SDF-1α treatment at 200 ng/ml and reduced using a blocking monoclonal antibody against CXCR4. We showed that at low SDF-1α concentration, RhoA was activated and overexpressed, while at high concentration Rac1 was promoting SDF-1α mediating-cell adhesion. CONCLUSION: We conclude that SDF-1α concentration modulates migration and adhesion of breast cancer cells, by controlling expression and activation of RhoGTPases.

Role of mesenchymal cells in the natural history of ovarian cancer: a review.

BACKGROUND: Ovarian cancer is the deadliest gynaecologic malignancy. Despite progresses in chemotherapy and ultra-radical surgeries, this locally metastatic disease presents a high rate of local recurrence advocating for the role of a peritoneal niche. For several years, it was believed that tumor initiation, progression and metastasis were merely due to the changes in the neoplastic cell population and the adjacent non-neoplastic tissues were regarded as bystanders. The importance of the tumor microenvironment and its cellular component emerged from studies on the histopathological sequence of changes at the interface between putative tumor cells and the surrounding non-neoplastic tissues during carcinogenesis. METHOD: In this review we aimed to describe the pro-tumoral crosstalk between ovarian cancer and mesenchymal stem cells. A PubMed search was performed for articles published pertaining to mesenchymal stem cells and specific to ovarian cancer. RESULTS: Mesenchymal stem cells participate to an elaborate crosstalk through direct and paracrine interaction with ovarian cancer cells. They play a role at different stages of the disease: survival and peritoneal infiltration at early stage, proliferation in distant sites, chemoresistance and recurrence at later stage. CONCLUSION: The dialogue between ovarian and mesenchymal stem cells induces the constitution of a pro-tumoral mesencrine niche. Understanding the dynamics of such interaction in a clinical setting might propose new therapeutic strategies.

[French survey on the management strategy for placenta accreta spectrum]. / Enquête nationale sur la stratégie de prise en charge du placenta accreta en France.

OBJECTIVE: Placenta accreta belongs to placenta accreta spectrum and is defined by an adhesion or even invasion of the placental villi in the myometrium. The main risk factor is a history of cesarean section. Its incidence is increasing following an increase in the cesarean section rate in recent years and the cause of severe maternal morbidity (hemorrhage, transfusions, hysterectomy). Treatment can be radical by cesarean section-hysterectomy or conservative with an attempt at uterine preservation. American, English, Canadian and international recommendations have been established but there are no French recommendations to date. The objective of this study was to investigate management strategy for placenta accreta in type III maternity hospitals in France. MATERIALS AND METHODS: An anonymous questionnaire was sent by email to the obstetrics referents of the university hospital centers in France with type III maternity. RESULTS: Forty-eight centers were approached, with a participation rate of 77%. CONCLUSION: The management of placenta accreta spectrum in France is relatively heterogeneous on several points such as multidisciplinary management, evaluation by placental MRI, preoperative urological evaluation, treatment adopted as first-line, cesarean section-hysterectomy or conservative treatment, therapeutic strategy according to the placental invasion. However, the literature is currently poor, which may explain divergent treatment.

Percutaneous cryoablation of abdominal wall endometriosis: An analysis of 38 patients.

PURPOSE: The purpose of this study was to evaluate the efficacy of percutaneous cryoablation in the treatment of abdominal wall endometriosis (AWE) nodules. MATERIALS AND METHODS: Thirty-eight women treated for symptomatic AWE nodules with percutaneous cryoablation under ultrasound and computed tomography (CT) guidance between May 2020 and July 2023 were retrospectively included. Pain was estimated using visual analog scale (VAS) and assessed at baseline, three months, six months, and 12 months after percutaneous cryoablation. Baseline VAS score, volume of AWE nodule and magnetic resonance imaging (MRI) features of AWE nodules were compared to those obtained after percutaneous cryoablation. Major complications, if any, were noted. RESULTS: Thirty-eight women with a median age of 35.5 years (interquartile range [IQR]: 32, 39; range: 24-48 years) and a total of 60 AWE nodules were treated. Percutaneous cryoablation was performed under local or regional anesthesia in 30 women (30/38; 79%). Significant decreases between initial median VAS score (7; IQR: 6, 8; range: 3-10) and median VAS score after treatment at three months (0; IQR: 0, 5; range; 0-8) (P < 0.001), six months (0; IQR: 0, 1; range; 0-10) (P < 0.001) and 12 months (0; IQR: 0, 2; range: 0-7) (P < 0.001) were observed. Percutaneous cryoablation resulted in effective pain relief in 31 out of 38 women (82%) at six months and 15 out of 18 women (83%) at 12 months. Contrast-enhanced MRI at six-month follow-up showed a significant decrease in the volume of AWE nodules and the absence of AWE nodule enhancement after treatment by comparison with baseline MRI (P < 0.001). No major complications were reported. CONCLUSION: Percutaneous cryoablation is an effective, minimally invasive intervention for the treatment of AWE nodules that conveys minimal or no morbidity.

Evaluation of the sentinel lymph node algorithm with blue dye labeling for early-stage endometrial cancer in a multicentric setting.

OBJECTIVES: Sentinel lymph node (SLN) removal may be a midterm between no and full pelvic dissection in early endometrial cancer. Whereas the use of blue dye alone in SLN detection has a poor accuracy, its integration in an SLN algorithm may yield better results and overcome hurdles such as the requirement of nuclear medicine facility. METHODS: Sixty-six patients with clinical stage I endometrial cancer were prospectively enrolled in a multicentre study between May 2003 and June 2009. Patent blue was injected intraoperatively into the cervix. We retrospectively assessed the accuracy of a previously described SLN algorithm consisting of the following sequence: (1) pelvic node area is inspected for removal of all mapped SLN and (2) excision of every suspicious non-SLN, (3) in the absence of mapping in a hemipelvis, a standard ipsilateral lymphadenectomy is then performed. RESULTS: Sentinel nodes were identified in 41 patients (62.1%), mostly in interiliac and obturator areas. None was detected in the para-aortic area. Detection was bilateral in 23 cases (56.1%). Seven patients (10.6%) had positive nodes. The false-negative rate was 40% using SLN detection alone. When the algorithm was applied, the false-negative rate was 14.3%. The use of a SLN algorithm would have avoided 53% of lymphadenectomies CONCLUSION: Our multicentric evaluation validates the use of a SLN algorithm based on blue-only sentinel node mapping in early-stage endometrial cancer. The application of such SLN algorithm should be evaluated in a prospective context and might lead to decrease unnecessary lymphadenectomies.
