Fostering Cardio-Endometriosis: A Call to Action for a Comprehensive Understanding of Cardiovascular Disease in Endometriosis.

Recently, a growing body of evidence has highlighted a concerning link between endometriosis and cardiovascular disease. Endometriosis, a chronic, inflammatory hormone-dependent condition affecting 5 to 10% of reproductive-aged women worldwide, has long been associated with reproductive and gynecological consequences. However, emerging research has suggested that it may also contribute to adverse cardiovascular outcomes. This paper aims to shed light on the importance of recognizing cardio-endometriosis as a new and developing sphere of research in the field of cardiology, thereby urging the medical community to address this pressing issue.

[Interest of multidisciplinary consultation meetings dedicated to endometriosis: From a series of 682 patients]. / Intérêt des réunions de concertation pluridisciplinaires dédiées à l'endométriose : à partir d'une série de 682 patientes.

OBJECTIVE: We decided to conduct a study based on these multidisciplinary team (MDT) in order to investigate their impact at the University Hospitals of Strasbourg and look for ways to improve this MDT. METHODS: This is a retrospective study of the 682 patients presented to endometriosis MDT from its inception in March 2017 to December 2020. RESULTS: The MDT decision was different from that initially proposed by the patient's referent for 406 patients (60%). Surgery was chosen for 417 patients (61%) and assisted reproduction for 261 patients (38%). A review of the MRI by a referring radiologist was carried out for 348 cases (51%), with a modification of the results for 255 patients (73%). Initial underestimation of lesions was noted in 198 cases. CONCLUSION: Our study has shown the importance of MDT in endometriosis since the therapeutic proposal was modified in 60% of cases. In addition, we supported the importance of radiologists specializing in this field since they made a modification in two-thirds of the MRIs reread. These results show the importance of collegial discussions, which can modify the decisions of medical teams. This underlines the importance of setting up endometriosis networks.

Effects of a physical activity and endometriosis-based education program delivered by videoconference on endometriosis symptoms: the CRESCENDO program (inCRease physical Exercise and Sport to Combat ENDOmetriosis) protocol study.

BACKGROUND: Endometriosis is a chronic disease characterized by growth of endometrial tissue outside the uterine cavity which could affect 200 million women (The term "woman" is used for convenience. Individuals gendered as man or as nonbinary can also suffer from this disease) worldwide. One of the most common symptoms of endometriosis is pelvic chronic pain associated with fatigue. This pain can cause psychological distress and interpersonal difficulties. As for several chronic diseases, adapted physical activity could help to manage the physical and psychological symptoms. The present study will investigate the effects of a videoconference-based adapted physical activity combined with endometriosis-based education program on quality of life, pain, fatigue, and other psychological symptoms and on physical activity. METHODS: This multicentric randomized-controlled trial will propose to 200 patients with endometriosis to be part of a trial which includes a 6-month program with 45 min to more than 120 min a week of adapted physical activity and/or 12 sessions of endometriosis-based education program. Effects of the program will be compared to a control group in which patients will be placed on a waiting list. All participants will be followed up 3 and 6 months after the intervention. None of the participants will be blind to the allocated trial arm. The primary outcome measure will be quality of life. Secondary outcomes will include endometriosis-related perceived pain, fatigue, physical activity, and also self-image, stereotypes, motivational variables, perceived support, kinesiophobia, basic psychological need related to physical activity, and physical activity barriers. General linear models and multilevel models will be performed. Predictor, moderator, and mediator variables will be investigated. DISCUSSION: This study is one of the first trials to test the effects of a combined adapted physical activity and education program for improving endometriosis symptoms and physical activity. The results will help to improve care for patients with endometriosis. TRIAL REGISTRATION: ClinicalTrials.gov, NCT05831735 . Date of registration: April 25, 2023.

Urological procedures performed by gynecologists: Activity profile in a gynecological surgery department, 10-year observation cohort.

INTRODUCTION: The proximity of the urinary tract to the female genital tract explains its possible involvement in pelvic gynaecological cancer or deep endometriosis. Surgical treatment is aimed at improving overall survival and recurrence-free survival of patients, as well as restoring normal anatomy and functional integrity depending on the pathology. These operations are accompanied by significant post-operative complications. Thus, the urological procedures performed must be rigorously justified, and the different resection and reconstruction techniques adapted to the pathology and the level of infiltration. OBJECTIVE: To describe the activity profile, over the last ten years, of a gynaecological surgery department in terms of urological procedures in the management of patients with deep endometriosis and pelvic carcinology. STUDY DESIGN: This is a monocentric retrospective observational study, including all patients who underwent a urological procedure by a gynaecological surgeon only, as part of the management of pelvic gynaecological cancers or deep endometriosis, at the University Hospital Centre (CHU) of Strasbourg, between January 1st 2010 and April 31st 2021. The variables studied were early postoperative complications, the rate of surgical reintervention, operating time, length of hospital stay, the need for peri-operative drainage or transfusion, and post-operative functional disorders. RESULTS: A total of 86 patients were included, 27 in the pelvic gynaecological cancer group and 59 in the deep endometriosis group. 61.6% of patients received uretero-vesical catheterization, 60.5% partial cystectomy, 10.5% psoic bladder ureteral reimplantation, and 3.5% trans-ileal Bricker skin ureterostomy. The mean operating time was 316 min in the pelvic gynaecological cancer group and 198.9 min in the deep endometriosis group. The average hospital stay was 11.5 days, 22.3 days for patients treated for pelvic cancer and 6.3 days for those treated for endometriosis. The rate of minor post-operative complications was 8.2% of cases, and major post-operative complications 17.4% of cases, the majority of which were in the gynecological cancer group. There were no cases of intra- or early post-operative death. Early postoperative urinary complications affected 14.0% of the total patients, mostly in the gynaecological cancer group with 33.3% of patients, but only 5.1% of patients in the deep endometriosis group. The total reoperation rate within 60 days postoperatively was 15.1%, 40.7% for patients treated for gynaecological cancer and 3.4% for those treated for deep pelvic endometriosis. The rate of reoperations for urinary complications was 11.6% of total patients, or 76.9% of total reoperations. 15 patients received labile blood products intra- or postoperatively, 11 in the pelvic gynaecological cancer group and 4 in the endometriosis group. CONCLUSION: Our overall results appear comparable to those reported in the literature and are particularly satisfactory in terms of post-operative complications after partial cystectomy in the management of deep endometriosis compared to other gynaecological departments. This work encourages us to continue and improve the training of gynaecological surgeons in terms of multidisciplinary surgical procedures, including urological ones, to obtain a global vision of the pathology and to allow an optimal quality of care for the patients.

Percutaneous Imaging-guided Cryoablation of Endometriosis Scars of the Anterior Abdominal Wall.

STUDY OBJECTIVE: To evaluate the safety and clinical efficacy of percutaneous imaging-guided cryoablation for the management of anterior abdominal wall endometriosis. DESIGN: Patients with abdominal wall endometriosis underwent percutaneous imaging-guided cryoablation and had a 6-month follow-up. SETTING: Data dealing with patients' and anterior abdominal wall endometriosis (AAWE) characteristics, cryoablation, and clinical and radiologic outcomes were retrospectively collected and analyzed. PATIENTS: Twenty-nine consecutive patients underwent cryoablation from June 2020 to September 2022. INTERVENTIONS: Interventions were performed under US/computed tomography (CT) guidance or magnetic resonance imaging (MRI) guidance. Cryoprobes were directly inserted into the AAWE, and cryoablation was performed with a single 5 to 10 minute freezing cycle, which was stopped when the iceball expanded 3 to 5 mm beyond AAWE borders as assessed on intra-procedural cross-sectional imaging. MEASUREMENTS AND MAIN RESULTS: Fifteen patients (15/29; 51.7%) had prior endometriosis, 28 (28/29; 95.5%) had previous cesarian section, and 22 (22/29; 75.9%) referred association between symptoms and menses. Cryoablation was performed under local (16/29; 55.2%) or general anesthesia (13/29; 44.8%) and mainly in an out-patient basis (18/20; 62%). There was only one (1/29; 3.5%) minor procedure-related complication. Complete symptom relief was recorded in 62.1% (18/29) and 72.4% (21/29) patients at 1 and 6 months, respectively. In the whole population, pain significantly dropped at 6 months compared to the baseline (1.1 ± 2.3; range 0-8 vs 7.1 ± 1.9; range 3-10; p <.05). Eight (8/29; 27.6%) patients presented residual symptoms at 6 months, and 4 (4/29; 13.8%) had an MRI-confirmed residual/recurring disease. Contrast-enhanced MRI obtained for the first 14 (14/29; 48.3%) patients of the series, all without signs of residual/recurring disease, demonstrated a significantly smaller ablation area compared to the baseline volume of the AAWE (1.0 cm3 ± 1.4; range 0-4.7; vs 11.1 ± 9.9 cm3; range 0.6-36.4; p <.05). CONCLUSION: Percutaneous imaging-guided cryoablation of AAWE is safe and clinically effective in achieving pain relief.

Vaginal and laparoscopic sub-urethral sling explantation.

INTRODUCTION AND HYPOTHESIS: The objective was to describe the different laparoscopic and vaginal steps of sub-urethral infected mesh explantation as well as an unexpected and unusual complication: a sub-mucosal calcification on the sub-urethral segment of the sling that was not infiltrating the urethra. METHODS: This was carried out at our University Teaching Hospital of Strasbourg. RESULTS: We show the complete removal of an infected retropubic sling in a patient who had already undergone three previous surgeries without resolution of symptoms. This is a difficult case requiring a laparoscopic approach of the space of Retzius, which has been less familiar to surgeons since the advent of the midurethral sling. We show how to approach this space in an inflammatory environment by specifying its anatomical limits. Moreover, a great deal can be learned from the occurrence of an infectious complication after the surgery and the presence of a large calcification on the prosthesis. In this context, we advise a systematic antibiotic treatment to avoid this kind of complication. CONCLUSIONS: Knowing the guidelines and the different surgical steps will help urogynecological surgeons to perform similar procedures in patients requiring removal of retropubic slings for complications such as infection and pain, where conservative management has not been successful. These cases must be discussed in a multidisciplinary meeting, as recommended by the French National Authority for Health, and managed in an expert establishment.

Deep infiltrating endometriosis: Laparoscopic nerve-sparing surgery and use of neutral argon plasma.

OBJECTIVE: To present a minimally approach to the management of deep pelvic endometriosis by nerve-sparing surgery and use of neutral argon plasma for extensive endometriotic lesions. DESIGN: This is a clinical case video of a 29 years-old patient, affected by deep pelvic endometriosis with primary dysmenorrhea, deep dyspareunia, chronic pelvic pain and dyschezia. Pelvic MRI shows a right ovarian endometrioma measuring 5 cm, a thickening of the right uterosacral ligament and a uterine torus nodule. SETTING: Laparoscopy video. INTERVENTION: This laparoscopic surgery begins by an adhesiolysis of the sigmoid and a blue tube test to check the correct permeability of the tubes. A bilateral ureterolysis is performed before the excision of a torus lesion and adhesiolysis of the rectovaginal septum. A fine dissection of the uterosacral ligament by nerve-sparing surgery is realized to respect the hypogastric nerve in the Okabayashi space. Endometriosis nodules of the lumbo-ovarian ligaments and multiples endometriosis peritoneal implants, inaccessible to a complete excision, are destroyed by argon plasma vaporization. A cystectomy of the right endometrioma and an appendectomy are performed at the end. CONCLUSION: The surgical management of deep infiltrating endometriosis is complex, with the recent contribution of new technical procedures such as nerve-sparing surgery to reduce postoperative urinary complications, or argon plasma for ablation of extended peritoneal implants or endometrioma to preserve ovarian function.

Bilateral posterior Richter sacrospinous fixation with native tissue: Anatomical and functional results and quality of life assessment over 10 years.

INTRODUCTION: Pelvic organ prolapse (POP) is a common condition that affects 50% of women who have given birth in their lifetime. With stop of vaginal mesh sale in 2019, the sacrospinous fixation technique according to Richter with native tissue has seen its incidence tripled in 15 years. Classically, sacrospinous fixation according to Richter is performed unilaterally, however its unilateral or bilateral character is controversial. Objective of this work is to evaluate the efficacy and safety of bilateral sacrospinous fixation according to Richter by the posterior approach with native tissue (SSB). METHODS: We performed a retrospective single-center study. From March 12, 2010 to March 23, 2020, all first-time operated patients who underwent SSB in CHU Strasbourg gynecological surgery unit for symptomatic POP management were included. The main endpoint of our work is the anatomical and functional success rate at 12 and 24 months. The secondary judgment criteria of our work were based on the postoperative evaluation of patient's quality of life according to the PFDI-20 score as well as the rate of postoperative complications. RESULTS: 77 patients were included in our work. The anatomical success rate at 12 months is 94 and 81% at 24 months regardless of the compartment affected. The functional success rate is 94% at 12 months and 82% at 24 months. Quality of life evaluation through the PFDI-20 scale revealed a clear improvement in the symptomatology related to POP: 127/300 +/- 27.3. preoperatively and 59.8 ± 14.7 postoperatively. CONCLUSION: Bilateral sacrospinous fixation according to Richter by posterior approach with native tissue is a safe and effective surgical technique allowing a clear improvement in patients quality of life.

Preliminary observational study of the implementation of hyperthermic intraperitoneal chemotherapy in ovarian cancer in the gynecological surgery department at the University Hospital of Strasbourg.

OBJECTIVE: According to French guidelines, hyperthermic intraperitoneal chemotherapy (HIPEC) can be performed for Federation of Gynecology and Obstetrics stage III primary epithelial ovarian, tubal, and peritoneal cancers that are initially unresectable after 3 or 4 cycles of intravenous chemotherapy. The main objective of this preliminary study was to analyze the components necessary for the establishment of HIPEC in an expert gynecological oncological surgery center. The secondary objective was to compare HIPEC using conventional laparotomy and laparoscopic approaches. METHODS: We conducted a single-center retrospective study of patients who received HIPEC. All patients who met the criteria of the French HIPEC guidelines were included from 2019 to 2021. RESULTS: Prior to HIPEC, there were a mean of 3.7 courses of neoadjuvant chemotherapy with carboplatin and paclitaxel. Of the 16 patients who received HIPEC, 9 (56.2%) underwent HIPEC laparoscopically, while 7 (43.8%) underwent laparotomy. There were no differences between the rates of intra- and postoperative complications between the two groups. (p > 0.05). The duration of hospitalization was significantly shorter in patients who were operated laparoscopically than in those treated using laparotomy (55.6% <10 days vs. 0 by laparotomy, p = 0.01). There was also a tendency, although not significant, for a more rapid resumption of adjuvant chemotherapy in the laparoscopy group, with 57.1% resuming chemotherapy in <6 weeks compared to 42.9% in the laparotomy group (p = 0.52). CONCLUSIONS: This study demonstrates the feasibility of HIPEC in a center with expertise in gynecological surgery when there is a suitable technical platform and close collaboration between the different teams involved. We also showed the first cases of HIPEC using laparoscopy, which seems to be a promising approach.

Feasibility and clinical value of virtual reality for deep infiltrating pelvic endometriosis: A case report.

Deep infiltrating pelvic endometriosis and its surgical management is associated with a risk of major postoperative complications. Magnetic Resonance Imaging (MRI) is recommended preoperatively in order to obtain the most precise mapping of the extent of endometriotic lesions. The aim of this work was to assess the feasibility and clinical interest of 3D modeling by surface rendering as a preoperative planning tool in a patient with deep infiltrating pelvic endometriosis. We report on a 42 years old patient with history of endometriosis and persistent pain underwent pre operative imaging with MRI that was consistent with deep infiltrating endometriosis. A 3D model of the deep infiltrating endometriosis was generated from the MRI and retrospectively compared to the intra-operative findings. The nodule's location and relationship to the uterus and the rectum was clearly defined by the 3D model and correlated with surgical findings. Virtual reality based on 3D models could be an interesting tool to assist in the preoperative planning of complex surgeries.

Endometriosis and cardiovascular disease.

Endometriosis is a chronic gynaecological disease affecting 1 in 10 reproductive-age women. It is defined as the presence of endometrium-like tissue outside the uterus. Beyond this placid anatomical definition, endometriosis is a complex, hormonal, inflammatory, and systemic condition that poses significant familial, psychological, and economic burden. The interaction between the cardiovascular system and endometriosis has become a field of interest as the underlying mutual mechanisms become better understood. On the basis of accumulating fundamental and clinical evidence, it is likely that there exists a close relationship between endometriosis and the cardiovascular system. Therefore, investigating the endometriosis-cardiovascular interaction is highly clinically significant. In this review, we highlight our current understanding of the pathophysiology of endometriosis with systemic hormonal, pro-inflammatory, pro-angiogenic, immunologic, and genetic processes beyond the peritoneal microenvironment. Additionally, we provide current clinical evidence about how endometriosis interacts with cardiovascular risk factors and cardiovascular disease (CVD). To date, only small associations between endometriosis and CVD have been reported in observational studies, inherently limited by the potential influence of unmeasured confounding. Cardiovascular disease in women with endometriosis remains understudied, under-recognized, and underdiagnosed. More detailed study of the cardiovascular-endometriosis interaction is needed to fully understand its clinical relevance, underlying pathophysiology, possible means of early diagnosis and prevention.

Laparoscopic En Bloc Pelvic Resection with Rectosigmoid Resection and Anastomosis for Stage IIB Ovarian Cancer: Hudson's Procedure Revisited.

STUDY OBJECTIVE: To demonstrate a systematic approach to the laparoscopic en bloc pelvic resection with rectosigmoid resection and anastomosis as part of ovarian cancer treatment in a tertiary gynecologic surgery referral center. DESIGN: This video illustrates an en bloc pelvic resection performed par laparoscopy in 10 steps. SETTING: A 56-year-old patient with an advanced high-grade serous ovarian cancer extending into the rectum was amenable to primary debulking surgery in accordance with the French guidelines [1]. In diagnostic laparoscopy, a bilateral adnexectomy was performed, and the pelvic carcinomatosis was considered primarily resectable. Histopathology of the subsequent en bloc resection was consistent with stage IIB high-grade serous ovarian cancer with an indication for adjuvant chemotherapy. INTERVENTION: The Hudson's procedure revisited consists of a radical monobloc excision by way of a completely extraperitoneal dissection and total mobilization of the rectum. In this case, owing to rectal invasion, we achieved a laparoscopic radical resection including rectosigmoidectomy and primary anastomosis without the need for a defunctioning stoma [2]. CONCLUSION: Traditionally, an en bloc pelvic resection with rectosigmoid resection and anastomosis was performed by laparotomy. The feasibility of performing laparoscopic optimal cytoreductive surgery in selected patients with advanced ovarian cancer was recently demonstrated without compromising survival in case of low residual disease. The prognosis depends rather on the resectability than on the operative access. However, the radicality and completeness of the cytoreduction, as well as the potential risk of tumor seeding, remain controversially discussed. Here, we demonstrate the minimally invasive approach following the same operative strategy as in open surgery. In this way, the radicality of the "en bloc resection" entailing avoidance of tumor rupture, less bleeding, and less urethral injury is combined with the benefits of a minimally invasive access. In expert hands, this procedure can be performed laparoscopically for other pelvic malignancies with peritoneal carcinomatosis.

Complete Laparoscopic Interval Debulking Surgery for Advanced Ovarian Cancer Achieves Similar Survival Outcomes to Open Approach: A Propensity-Matched Study.

To assess the laparoscopic interval debulking surgery (IDS) outcomes compared to laparotomy, by analyzing the overall survival (OS) and the progression free survival (PFS), as well as the intra- and post-operative morbidity.In this retrospective propensity-score-matched cohort study, all patients with stage III or IV FIGO (International Federation of Gynecology and Obstetrics) serous ovarian cancer, undergoing complete IDS after neoadjuvant chemotherapy, from January 1st of 2009 to June 1st 2019, were included.Thirty-seven patients were included in the laparoscopy group and 40 in the laparotomy group. There was no significant difference in terms of median OS between laparoscopy and laparotomy (23.1 months [95% CI 15.7-29.7] versus 26.3 months [95% CI 21.7-31.7], respectively, p = 0.17) and median PFS (14.8 months [95% CI 10.6-21.5] versus 12 months [95% CI 11-15.1], p = 0.057). After applying the propensity score, 25 patients were included in each group. Laparoscopy was associated with significantly less early postoperative complications (6 versus 17, p = 0.01) and shorter hospital stay (7.6 days versus 12.1, p < 0.001) and a significantly better OS (HR 0.45 [95% CI 0.19-0.95], p = 0.04), but with no significant difference in terms of PFS (HR 0.71 [95% CI 0.27-1.88], p = 0.49).In carefully-selected patients with advanced ovarian cancer, complete laparoscopic interval debulking surgery achieves similar survival outcomes to open laparotomy. Therefore, laparoscopy appears as a safe alternative to laparotomy for IDS after NACT in selected patients with advanced ovarian cancer and a low burden of disease.

Impact of surgery for colorectal endometriosis on postoperative fertility and pregnancy outcomes.

INTRODUCTION: Deep infiltrative endometriosis can lead to infertility with a spontaneous pregnancy rate between 8.7 and 13%. Surgical treatment of bowel endometriosis may improve spontaneous and ART fertility. The aim of this study was to evaluate post-operative fertility according to the surgical technic used (shaving vs. bowel resection). MATERIAL AND METHOD: A retrospective, monocentric study was carried-out in the University Hospital of Strasbourg, France, from September 2009 to October 2016. All patients with a desire to become pregnant and treated for colorectal deep infiltrating endometriosis were included. Two groups were analyzed and compared: shaving treatment vs. digestive resection (discoid or segmental). The primary outcome was pregnancy rate after surgery. Secondary outcomes were: mode of pregnancy occurrence (spontaneous versus ART), time of onset, term at birth, occurrence of complications during pregnancy. RESULTS: 94 patients were included (39 had a bowel resection and 55 a shaving). Both groups had similar pre-operative characteristics. The pregnancy rate was 52,1% for the total population with no significant differences between the two groups (p = 0.68). However, we found a significantly higher spontaneous pregnancies rate among the resection group with 73.7% (p = 0,0086). Pregnancy complications occurred in 50% of pregnancies, regardless of the surgical technic used. CONCLUSION: This study suggests that, for patients with colorectal DIE, surgical treatment improves overall fertility. Furthermore, resection surgery seems to significantly improve the occurrence of spontaneous pregnancies. However, this surgery is not without risks and multidisciplinary discussions and thorough information to the patient are a prerequisite.

Nerve Anatomy Around Lumbo-aortic Lymphadenectomy by Retroperitoneal Approach.

STUDY OBJECTIVE: To describe the anatomy of the nerves during a laparoscopic retroperitoneal para-aortic lymphadenectomy with prioritization of their preservation. DESIGN: Demonstration of a nerve-preserving para-aortic lymphadenectomy. SETTING: A 65-year-old woman with no significant medical history underwent diagnostic laparoscopy for evaluation of a right ovarian mass. In the absence of peritoneal carcinomatosis, bilateral adnexectomy wasperformed with pathology revealing a high-grade tubo-ovarian serous carcinoma. In accordance with French Guidelines for management of ovarian cancer, operative staging including pelvic and para-aortic lymphadenectomy was recommended [1]. Final pathology following staging surgery was consistent with stage IA high-grade serous ovarian cancer prompting administration of adjuvant chemotherapy postoperatively. INTERVENTIONS: We performed a lumbo-aortic lymphadenectomy with preservation of the following nerves: the superior hypogastric plexus, the lumbar splanchnic nerves and the sympathetic trunk. CONCLUSION: Although there are conflicting data as to the benefit of staging lymphadenectomy in women with presumed early stage high-grade serous ovarian cancer, current French Guidelines recommend its performance. When doing so, effort should be made to avoid injury to adjacent normal structures, and in doing so, minimize potential morbidity. The neural structures preserved in this case are part of the sympathetic contingent and participate in the innervation of the abdomen and pelvic viscera. The sympathetic contingent is responsible for the vasomotricity but is also involved in the contraction of the internal genitalia during orgasm and in the inhibition of the peristaltic contractions of the rectum. As such, its preservation may avoid certain postoperative complaints. When possible to do so without compromising essential elements of a cancer surgery, preservation of nerves should be considered.

Basics of immunotherapy for epithelial ovarian cancer.

Epithelial ovarian cancer (EOC) is the most lethal of all gynecological cancers. Despite excellent responses to standard treatment in approximately 70% of patients, most of them will relapse within 5 years of initial treatment and many of them will develop chemotherapy-resistant disease. It is then important to find other means of treatment for these patients such as immunotherapy or targeted therapy. To understand immunotherapy, it is important to explain the dynamic interplay between cancer and the immune system. Compared to traditional tumor therapies, immunotherapy acts primarily on the immune system or the tumor microenvironment but not directly on the tumor cells, and it may also promote synergistic anti-tumor actions as part of a combined treatment. The aim of this narrative review is to provide a basic understanding of immunotherapy the interest of this treatment in EOC, and to present the main ongoing studies that could change patient management in the future.

Bowel resection performed by gynecologists - Outcomes and learning curves. Activity profile in a Gynecology Department: 7-year observational cohort.

OBJECTIVE: Bowel resection is frequently used when performing oncological surgery to obtain complete cytoreduction or to remove endometriosis in case of intestinal invasion. Acquiring the surgical skills to perform this kind of procedure is crucial to offer to our patients an optimal management. The aim of this study is to describe a 7-years surgical experience in bowel resections of a gynecologic surgeon and to determine his learning curves. STUDY DESIGN: This is a monocentric retrospective cohort study reporting digestive resection performed between January 2013 and April 2020 in the Gynecology Department of Strasbourg University Hospital. Ninety-one consecutive patients were assigned in two groups: gynecological cancer (n = 44) and deep infiltrating endometriosis (DIE) (n = 47). The main outcome measure was the postoperative complications rate at 30 days, based on the modified Clavien-Dindo severity system. Learning curves were evaluated using cumulative sum (CUSUM) analysis of operative time and risk-adjusted cumulative sum (RA-CUSUM) analysis of severe perioperative complications. Identification of predictive factors for operation duration and severe perioperative complication occurrence was conducted using multivariate analysis. RESULTS: Minor complications were found in 25% of cases. Major complication rate (Clavien-Dindo ≥ IIIa) was 14% in total and only involved patients operated for cancer. The CUSUM curve for operative time peaked at the 35th case and showed a downward slope after the 45th case. Significant predictive factors of operating time were cytoreductive tumoral surgery, size of the bowel resection and laparoscopic surgery, while learning phase 3 significantly decreased it. The RA-CUSUM curve for severe perioperative complications (Clavien-Dindo ≥ IIIa) showed a progressive decrease in the complication rate as the number of interventions increases without showing clear inflection points. Only cardiopulmonary pathologies were found as significant predictive factor of severe complications. CONCLUSION: Proficiency in performing highly complex surgery was achieved after approximately 45 cases, cancer and DIE all together. Acceptable rates of severe perioperative complications were observed even during the initial learning period and are comparable with those found in the literature concerning bowel resection performed by gynecologic oncologists but also by general and digestive surgeons.
