IntroductionEndometriosis affects 5–10% of women during reproductive years, with a 20–30% incidence among those with infertility. Deep infiltrating endometriosis (DIE) affects 10–15% of women of childbearing age and 50% of infertile women. When hormonal therapy and conservative surgery prove ineffective, total hysterectomy with or without bilateral salpingo-oophorectomy may be the ultimate therapeutic option. Laparoscopic surgery is the gold standard for treating endometriosis, offering effective disease eradication, safety, reduced pain, shorter hospital stay and faster recovery compared with laparotomy. However, patients undergoing total laparoscopic hysterectomy with DIE have higher risks of complications and organ damage, particularly urinary tract damage. Robot-assisted laparoscopic hysterectomy has emerged as a promising alternative, with a significantly lower conversion rate than total laparoscopic hysterectomy in patients with endometriosis. This study evaluates the safety and efficacy of robot-assisted total laparoscopic hysterectomy (RATLH) versus total laparoscopic hysterectomy (TLH) in the management of DIE. We hypothesise that robot-assisted laparoscopic hysterectomy will result in fewer complications and better outcomes compared with total laparoscopic hysterectomy in DIE patients.Methods and analysisThe ENDORAS trial is a prospective, multicentre, open-label, randomised controlled trial conducted in French reference hospitals specialising in endometriosis surgery. A total of 224 adult women patients will be enrolled in this study if they have DIE with adenomyosis, and without digestive tract involvement as confirmed by MRI. Participants will be randomised to undergo either RATLH or TLH. The primary outcome will be the intraoperative and postoperative complication rates, classified according to the Clavien-Dindo classification (grade 2 or above) at the 3-month postoperative follow-up. Among the secondary outcomes, we will evaluate the quality of life using various questionnaires, including the Endometriosis Health Profile-30, the Short Form-306 and the Female Sexual Function Index.Ethics and disseminationThe ENDORAS trial will be conducted in accordance with the International Council on Harmonization Good Clinical Practice guidelines. All trial documents and procedures have been reviewed and approved by the Ethics Committee Ile de France II (approval ID number: 24.01408.000300). Informed consent will be obtained during the preoperative check-up by the operating gynaecologist. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media, broadcast media, print media and the internet.Trial registration numberNCT06445179.

ObjectiveTo evaluate the use of new bipolar vessel sealing system like LigaSure™ compared to the standard surgical technique (suture) during emergency peripartum hysterectomy (EPH).MethodsA 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.ResultsAmong 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.ConclusionBipolar 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.

Surgical peritoneal stress creates a pro-metastatic niche promoting resistance to apoptosis via IL-8
2018
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.

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.

To evaluate immediate perineal and neonatal morbidity associated with instrumental rotations performed with Thierry's spatulas for the management of persistent posterior occiput (OP) positions.
Retrospective study including all persistent occiput posterior positions with vaginal OP delivery, from August 2006 to September 2007. Occiput anterior deliveries following successful instrumental rotation were included as well. We compared maternal and neonatal immediate outcomes between spontaneous deliveries, rotational and non rotational assisted deliveries, using χ(2) and Anova tests.
157 patients were enrolled, comprising 46 OP spontaneous deliveries, 58 assisted OP deliveries and 53 deliveries after rotational procedure. Instrumental rotation failed in 9 cases. Mean age and parity were significantly higher in the spontaneous delivery group, while labor duration was shorter. There were no significant differences in the rate of severe perineal tears and neonatal adverse outcomes between the 3 groups.
Instrumental rotation using Thierry's spatulas was not associated with a reduced risk of maternal and neonatal morbidity for persistent OP deliveries. Further studies are required to define the true interest of such procedure in modern obstetrics.

Are Early Relapses in Advanced-Stage Ovarian Cancer Doomed to a Poor Prognosis?
2016
Early recurrence (ER) after completion of therapeutic regimen in advanced-stage ovarian cancer is a challenging clinical situation. Patients are perceived as invariably having a poor prognosis. We investigated the possibility of defining different prognostic subgroups and the parameters implicated in prognosis of ER patients.
We analyzed a multi-centric database of 527 FIGO stage IIIC and IV ovarian cancer patients. We defined patients relapsing within 12 months as ER and investigated using Cox logistic regression the prognostic factors in ER group. We subsequently divided ER patients into good and poor prognosis groups according to a lower or higher overall survival (OS) at 12 months after relapse and determined parameters associated to poor prognosis.
The median follow up was 49 months. One hundred and thirty eight patients recurred within 12 months. OS and Disease Free Survival (DFS) were 24.6 and 8.6 months, respectively, in this group of patients. Among the ER patients, 73 had a poor prognosis with an OS after relapse below 12 months (mean OS = 5.2 months) and 65 survived after one year (mean OS = 26.9 months). Residual disease (RD) after debulking surgery and mucinous histological subtype negatively impacted prognosis (HR = 1.758, p = 0.017 and HR = 8.641, p = 0.001 respectively). The relative risk of death within 12 months following relapse in ER patients was 1.61 according to RD status. However, RD did not affect DFS (HR = 0.889, p = 0.5).
ER in advanced-stage ovarian cancer does not inevitably portend a short-term poor prognosis. RD status after initial cytoreduction strongly modulates OS, that gives additional support to the concept of maximum surgical effort even in patients who will experience early recurrence. The heterogeneity in outcomes within the ER group suggests a role for tumor biology in addition to classical clinical parameters.

PurposeTo 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.MethodsA 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.ResultsAmong 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.ConclusionsOP operative deliveries are associated with significant perineal morbidity and pelvic floor dysfunction at 6 months postpartum.

MRI and rectal endoscopy sonography performance to diagnose the digestive depth infiltration of pelvic endometriosis
2023
IntroductionThe 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 methodWe 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.ResultsFifty 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)].ConclusionOur 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.

Vaginal Evisceration: An Unexpected Complication of Conization
2014
Large loop excision of the transformation zone (LLETZ) is routinely performed for the management of high grade intracervical neoplasia (CIN). Several uncommon complications have been described, including postoperative peritonitis, pseudoaneurysm of uterine artery, and bowel fistula. We report a unique case of postoperative vaginal evisceration and the subsequent management. Case. A 73-years-old woman underwent LLETZ for high grade CIN. On postoperative day 3, she was admitted for small bowel evisceration through the vagina. Surgical management was based on combined laparoscopic and transvaginal approach and consisted in bowel inspection and reinstatement, peritoneal washing, and dehiscence repair. Conclusions. Vaginal evisceration is a rare but potentially serious complication of pelvic surgery. This case report is to make clinicians aware of such complication following LLETZ and its management.
