[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.

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.

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.

Lipid Intake and Breast Cancer Risk: Is There a Link? A New Focus and Meta-Analysis.

Objective: To determine if there is an association between total lipid intake, saturated fatty acid (SFA), Poly- and Mono-Unsaturated Fatty Acid (PUFA and MUFA) and cholesterol intake and breast cancer risk. Materials and Methods: We conducted a systematic review of the literature and a meta-analysis following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We included all cohort and case-control studies published up to December 2020 with subgroup analysis according to menopausal status. Results: We included 44 articles for analysis. There was no association between total fat, SFA, MUFA, PUFA and cholesterol intake and breast cancer in the general population and in pre-menopausal women. In postmenopausal women, high SFA consumption was associated with increased breast cancer risk in case-control studies [relative risk (RR): 1.12; confidence interval (CI) 95%: 1.03-1.21; p = 0.006 but not in cohort studies (RR: 1.01; CI 95%: 0.85-1.19; p = 0.93). Conclusion: There was a weak association between high SFA consumption and breast cancer risk in post-menopausal women, however there was high heterogeneity for this analysis. As lipids can have different actions in the same family, studies should rather focus on specific lipid consumption.

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.

Cesarean scar pregnancy: Two case report and therapeutic management algorithm.

OBJECTIVE: We aimed to present two cases of cesarean scar pregnancy (CSP) and a literature review to discuss their management. CASES: We reported two cases of cesarean scar pregnancy (CSP) treated in Strasbourg's University Hospital between 2016 and 2018 and carried out an updated literature review concerning their treatment. RESULTS: The first case is a superficial implantation CSP managed by methotrexate (MTX) then ligation of the uterine arteries and echo-guided aspiration. The second case is a deep implantation CSP managed by MTX and then laparoscopic excision with clamping of the uterine arteries. In the literature, the most commonly used treatments are: MTX, echo-guided aspiration, and the combination of uterine artery embolization followed by echo-guided aspiration. CONCLUSION: We established an algorithm in which CSP treatment by MTX can be considered alone if criteria are met. If not, surgery, chosen according to the depth of implantation, will be associated with MTX with a preventive hemostasis procedure by embolization or ligation of the uterine arteries.

Augmented reality in gynecologic laparoscopic surgery: development, evaluation of accuracy and clinical relevance of a device useful to identify ureters during surgery.

OBJECTIVE: To develop and evaluate a non-invasive surgical assistance based on augmented reality (AR) in the detection of ureters on animal model. METHOD: After an experimental prototyping step on two pigs to determine the optimal conditions for visualization of the ureter in AR, three pigs were operated three times at 1 week intervals. The intervention consisted of an identification of the ureter, with and without the assistance of AR. At the end of the intervention, a clip was placed on the AR-proposed ureter to evaluate its accuracy. By doing a cone beam computed tomography, we measured the distance between the contrasted ureter and the clips in the acquired volume. Thirteen videos were recorded, allowing subsequent evaluation of the clinical relevance of the device. RESULTS: The feasibility of the technique has been confirmed. The margin of error was 1.77 mm (± 1.56 mm) for ureter localization accuracy. In order to evaluate the perceived relevance and accuracy in the detection of AR-assisted ureter, 58 gynecological surgeons were shown the videos then questioned. Of the 754 responses obtained (13 videos × 58 surgeons), the ureter was identified in direct vision in 31.2% of cases versus 81.7% in AR (p value 3.62 × 10-7). When looking at pigs that had already had one or two operations, the ureter was identified in only 16% of cases with direct vision compared to 76.1% with AR (p-value 5.48 × 10-19). In addition, 67% of surgeons felt that AR allowed them to better identify the ureters and 61% that AR reconstruction was accurate. CONCLUSION: This first AR device showed a satisfactory precision in the detection of ureters with a favorable opinion of surgeons. This surgical assistance system could be helpful in the performance of difficult procedures, for example in the case of patients, which have undergone multiple surgeries in the past.

A novel machine learning-derived decision tree including uPA/PAI-1 for breast cancer care.

Background uPA and PAI-1 are breast cancer biomarkers that evaluate the benefit of chemotherapy (CT) for HER2-negative, estrogen receptor-positive, low or intermediate grade patients. Our objectives were to observe clinical routine use of uPA/PAI-1 and to build a new therapeutic decision tree integrating uPA/PAI-1. Methods We observed the concordance between CT indications proposed by a canonical decision tree representative of French practices (not including uPA/PAI-1) and actual CT prescriptions decided by a medical board which included uPA/PAI-1. We used a method of machine learning for the analysis of concordant and non-concordant CT prescriptions to generate a novel scheme for CT indications. Results We observed a concordance rate of 71% between indications proposed by the canonical decision tree and actual prescriptions. Discrepancies were due to CT contraindications, high tumor grade and uPA/PAI-1 level. Altogether, uPA/PAI-1 were a decisive factor for the final decision in 17% of cases by avoiding CT prescription in two-thirds of cases and inducing CT in other cases. Remarkably, we noted that in routine practice, elevated uPA/PAI-1 levels seem not to be considered as a sufficient indication for CT for N≤3, Ki 67≤30% tumors, but are considered in association with at least one additional marker such as Ki 67>14%, vascular invasion and ER-H score <150. Conclusions This study highlights that in the routine clinical practice uPA/PAI-1 are never used as the sole indication for CT. Combined with other routinely used biomarkers, uPA/PAI-1 present an added value to orientate the therapeutic choice.

Type B Laparoscopic Radical Trachelectomy with Uterine Artery Preservation for Stage IB1 Cervical Cancer.

STUDY OBJECTIVE: Radical trachelectomy has emerged as a valuable fertility-preserving treatment option for young women with early-stage cervical cancer [1]. Laparoscopic radical trachelectomy performed by trained surgeons can be a feasible and safe therapeutic option as a fertility-sparing surgical technique [2,3]. To the best of our knowledge, this is the first time the total laparoscopic approach of radical trachelectomy is being published. In this video, rather than the description of the technique step by step, we show how to conserve uterine arteries even if the importance of such conservation is questionable. DESIGN: A case report. SETTING: A tertiary referral center in Strasbourg, France. PATIENT: A 37-year-old patient with no medical history who presented with stage IB1 invasive epidermoid cervical cancer. INTERVENTION: In this video, we describe the fertility-sparing surgical procedure consisting of type B total laparoscopic radical trachelectomy with uterine artery preservation. The procedure consists of the following 10 steps: step 1, bilateral pelvic lymphadenectomy and opening of the para vesical fossa; step 2, opening of the pararectal fossa in between the ureter and the internal iliac artery on each side; step 3, ureteric dissection up to the ureteric canal; step 4, opening of the vesicouterine space and section of the vesicouterine ligament; step 5, posterior dissection with division of the uterosacral ligament approximately 20 mm from the uterine insertion; step 6, section of the descending branch of the uterine artery and skeletonization of the ascending branch up to the uterine isthmus level; step 7, trachelectomy with a monopolar hook; step 8, laparoscopic isthmovaginal stitches; step 9, laparoscopic cerclage; and step 10, peritoneal closure. MEASUREMENTS AND MAIN RESULTS: The operative time was 420 minutes. The intraoperative blood loss was <200 mL. The operation was performed successfully with no intraoperative complications. The resection margins were safe. The patient was discharged on day 4. After 2 months, no late complications or recurrence were detected, and the patient had normal menstruation. CONCLUSION: Type B laparoscopic radical trachelectomy with uterine artery preservation appears to be a safe option for women who intend to maintain their desire for a future pregnancy.

Cesarean Scar Ectopic Pregnancy: Laparoscopic Resection and Total Scar Dehiscence Repair.

STUDY OBJECTIVE: To illustrate a laparoscopic technique for the resection of cesarean scar ectopic pregnancy, associated with isthmocele repair. DESIGN: Case report (Canadian Task Force classification III). SETTING: A tertiary referral center in Strasbourg, France. BACKGROUND: Cesarean scar pregnancy is a rare form of ectopic pregnancy. The major risk of this type of pregnancy is the early uterine rupture with massive, sometimes life-threatening, bleeding. Thus, active management of these pregnancies starting immediately after diagnosis is crucial. Therapeutic options can be medical, surgical, or a combination. Numerous case reports or case series can be found in the literature, but there are few clinical studies, which are difficult to conduct because of case rarity and inconclusiveness. A 2016 meta-analysis that included 194 articles published between 1978 and 2014 (126 case reports, 45 cases series, and 23 clinical studies) concluded that hysteroscopy or laparoscopic hysterotomy seems to be the best first-line approach to treating cesarean scar ectopic pregnancy, with uterine artery embolization reserved for significant bleeding and/or a high suspicion index for arteriovenous malformation [1]. There is no consensus on the treatment of reference, however. PATIENT: The case involves a 38-year-old primiparous women who underwent a cesarean section delivery in 2010 and who was diagnosed by ultrasound scan at 7 weeks gestation with cesarean scar ectopic pregnancy, which was confirmed by pelvic magnetic resonance imaging. The patient initially received medical treatment with 2 intramuscular injections of methotrexate and one local intragestational injection of KCl. Her initial human chorionic gonadotropin (hCG) level was 82 000 IU/L. Rigorous weekly biological and ultrasound monitoring revealed an involution of the ectopic pregnancy associated with decreasing hCG. No bleeding or infectious complications occurred during this period. After 10 weeks of monitoring, her hCG had stabilized at 300 IU/L, and a residual image persisted next to the cesarean scar, and thus surgical treatment was considered. INTERVENTION: This video illustrates the laparoscopic resection of a cesarean scar ectopic pregnancy associated with isthmocele repair. The originality of this video lies in the fact that it is the first demonstration of the laparoscopic treatment of total caesarean scar dehiscence. MEASUREMENTS AND MAIN RESULTS: The total operative time was 180 minutes. First, hysteroscopic evaluation revealed the cesarean scar dehiscence and the posterior pole of the ectopic pregnancy. Then the diagnosis of cesarean scar ectopic pregnancy was confirmed laparoscopically. The utero-ombilical truncs were clamped bilaterally. Complete enucleation of pregnancy was achieved after dissection of the vesicouterine peritoneum. Isthmocele repair was performed with closure in 2 planes. A blue dye test confirmed the tightness of the stitches. The utero-ombilical truncs were unclamped, and antiadhesion gel was applied to the new uterine scar [1]. The operation was performed successfully without complications. Intraoperative blood loss was <100 mL. The patient was discharged on postoperative day 3. No immediate complications were noticed. At 1 month after the intervention, ultrasound was normal. CONCLUSION: Surgical management of caesarean scar ectopic pregnancy with total dehiscence of hysterotomy can be performed safely and efficiently under laparoscopy.

Relevance of breast MRI in determining the size and focality of invasive breast cancer treated by mastectomy: a prospective study.

BACKGROUND: The aim of this study was the evaluation of breast MRI in determining the size and focality of invasive non-metastatic breast cancers. METHODS: The prospective, single-centre study conducted in 2015 compared preoperative MRI with histological analysis of mastectomy. RESULTS: One hundred one mastectomies from 98 patients were extensively analysed. The rates of false-positive and false-negative MRI were 2 and 4% respectively. The sensitivity of breast MRI was 84.7% for the detection of all invasive foci, 69% for single foci and 65.7% for multiple foci. In the evaluation of tumour size, the Spearman rank correlation coefficient r between the sizes obtained by MRI and histology was 0.62. The MRI-based prediction of a complete response to neoadjuvant chemotherapy was 75%. DISCUSSION: MRI exhibits high sensitivity in the detection of invasive breast cancers. False positives were linked to the inflammatory nature of the tumour bed. False negatives were associated with small or low-grade tumours and their retro-areolar location. The size of T1 tumours was overestimated by an average of 7%, but MRI was the most efficient procedure. The sensitivity of MRI for the diagnosis of unifocal tumours was higher than that for multifocal sites. Our study confirmed the positive contribution of preoperative MRI for invasive lobular carcinomas and complete response predictions after neoadjuvant chemotherapy.

Evaluation of long-term neurodevelopment in twin-twin transfusion syndrome after laser therapy.

OBJECTIVE: The primary objective of our study was to evaluate the long-term neurodevelopment outcome after laser surgery for twin-twin transfusion syndrome (TTTS). The secondary objective was to identify perinatal prognostic factors associated with neurodevelopmental impairment. METHOD: This was a single-center cohort prospective study carried out in pregnancies complicated by TTTS and treated by laser. Neurodevleopmental assesment included the administration of Ages and Stages Questionnaires® (ASQ), for the infants between 2 and 5 years of age. RESULTS: A total of 187 patients underwent a laser for TTTS between 2004 and 2013. Significant brain lesions were detected in eight (2.9%) cases by ultrasound and/or magnetic resonance imaging including intraventricular hemorrhage, periventricular leukomalacia, and porencephaly. Questionnaires were administered to 126 children (50.4%) at 24 months or older at the moment of testing. There were 13.5% of those infants who had an abnormal ASQ (established as one area or more scoring < 2 SD) at 3.6 years ±1.3 follow-up. There was a higher rate of abnormal ASQ among the infants with a birth weight below the fifth percentile (p = 0.036). CONCLUSION: Twin-twin transfusion syndrome is associated with a risk of abnormal neurological development, even in case of laser surgery. Further studies are necessary to identify the risk factors for neurological impairment. © 2016 John Wiley & Sons, Ltd.
