Training for next generation surgeons: a pilot study of robot-assisted hysterectomy managed by resident using dual console.

PURPOSE: To assess feasibility of a standardized robot-assisted hysterectomy managed by resident and supervised by senior surgeon using dual-console on a 21-step grid (max score = 42) assessing resident autonomy. METHODS: A total of seven patients managed between September 2019 and March 2020 by six residents in gynecology and obstetrics were included. Standardized robot-assisted hysterectomy for endometrial cancer or adenomyosis was performed. RESULTS: No conversion to laparotomy, no intra- or post-operative incidents were reported. Mean score on the evaluation scale was 29.8 out of 42 (SD = 7.3). Mean operative time was 104 min (SD = 23). Mean average suturing time was, respectively, 335 s (SD = 57 s) and 270 s (SD = 53 s) for the first and the fourth knot. There was a 65 s improvement between the first and the fourth intracorporeal knot (p = 0.043). The perceived workload evaluated with the NASA TLX score showed a low level of stress (Temporal demand = 1.6 /10), and a low level of frustration (Frustration level = 3.6/10). Experience gained during the surgery was felt to be important (Commitment = 8.6/10). CONCLUSION: Standardized robot-assisted hysterectomy managed by a resident supervised by a senior surgeon using the dual-console seems feasible. This tool could be useful to assess residents' surgical skills.

Value of pelvic examination in women with pelvic organ prolapse: A systematic review.

BACKGROUND: Recent recommendations from the French High Authority of Health on pelvic organ prolapse (POP) management underline the value of a pelvic examination. OBJECTIVES: The aim of this paper was to analyze the literature and identify the best evidence available regarding pelvic examination for women presenting prolapse-associated symptoms in terms of diagnosis and predictability of treatment success. SEARCH STRATEGY: The databases were queried similarly using Medical Subject Headings (MeSH) and non-MeSH terms broadly related to pelvic examination and POP management. SELECTION CRITERIA: We included studies assessing the diagnostic contribution of pelvic examination (correlation with symptoms) and its value for assessing the risk of pessary failure or recurrence after reconstructive surgery. DATA COLLECTION AND ANALYSIS: We assessed peer-reviewed articles on PubMed, Embase, and Cochrane database up to May 2023. The methodological quality of all the included studies was assessed using the ROBINS-E or RoB2 tools. MAIN RESULTS: In all, 67 studies were retained for the review. Prolapse-associated symptoms are poorly correlated with POP diagnosis. The symptom that is best correlated with the POP stage is the presence of a vaginal bulge (moderate to good correlation). The factors most strongly associated with the risk of recurrence after surgery or pessary failure are clinical: essentially a higher POP stage before surgery, levator ani muscle avulsion, and vaginal and genital measurements. CONCLUSIONS: In women complaining of prolapse-associated symptoms, a pelvic examination (vaginal speculum and digital vaginal examination) can confirm the presence of POP and identify risk factors for treatment failure or recurrence after surgical management or pessary placement. A higher stage of POP and levator ani muscle avulsion-discernible on pelvic examination-are major risk factors for POP recurrence or treatment failure. These features must be taken into account in the treatment choice and discussed with the patient.

[Pelvic exam in gynecology and obstetrics: Guidelines for clinical practice]. / Examen pelvien en gynécologie et obstétrique : recommandations pour la pratique clinique.

OBJECTIVE: To provide guidelines for the pelvic clinical exam in gynecology and obstetrics. MATERIAL AND METHODS: A multidisciplinary experts consensus committee of 45 experts was formed, including representatives of patients' associations and users of the health system. The entire guidelines process was conducted independently of any funding. The authors were advised to follow the rules of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS: The committee studied 40 questions within 4 fields for symptomatic or asymptomatic women (emergency conditions, gynecological consultation, gynecological diseases, obstetrics, and pregnancy). Each question was formulated in a PICO (Patients, Intervention, Comparison, Outcome) format and the evidence profiles were produced. The literature review and recommendations were made according to the GRADE® methodology. RESULTS: The experts' synthesis work and the application of the GRADE method resulted in 27 recommendations. Among the formalized recommendations, 17 present a strong agreement, 7 a weak agreement and 3 an expert consensus agreement. Thirteen questions resulted in an absence of recommendation due to lack of evidence in the literature. CONCLUSIONS: The need to perform clinical examination in gynecological and obstetrics patients was specified in 27 pre-defined situations based on scientific evidence. More research is required to investigate the benefit in other cases.

Uterine Factor Infertility, a Systematic Review.

Uterine factor infertility (UFI) is defined as a condition resulting from either a complete lack of a uterus or a non-functioning uterus due to many causes. The exact prevalence of UFI is currently unknown, while treatments to achieve pregnancy are very limited. To evaluate the prevalence of this condition within its different causes, we carried out a worldwide systematic review on UFI. We performed research on the prevalence of UFI and its various causes throughout the world, according to the PRISMA criteria. A total of 188 studies were included in qualitative synthesis. UFI accounted for 2.1 to 16.7% of the causes of female infertility. We tried to evaluate the proportion of the different causes of UFI: uterine agenesia, hysterectomies, uterine malformations, uterine irradiation, adenomyosis, synechiae and Asherman syndrome, uterine myomas and uterine polyps. However, the data available in countries and studies were highly heterogenous. This present systematic review underlines the lack of a consensual definition of UFI. A national register of patients with UFI based on a consensual definition of Absolute Uterine Factor Infertility and Non-Absolute Uterine Factor Infertility would be helpful for women, whose desire for pregnancy has reached a dead end.

Use of uterine manipulator in endometrial cancer: A French survey from Francogyn group.

INTRODUCTION: Since the LACC study in 2018, the use of the uterine manipulator (UM) has been questioned in Oncological surgery. Nowadays, there are few data on UM use in patients eligible for minimally invasive surgery for endometrial cancer. Our objective was to evaluate the practices and modalities of UM use by French onco-gynecologic surgeons in the management of endometrial cancer. METHODS: We surveyed the practices of 3 French medical societies-affiliated onco-gynecological surgeons with a web questionnaire composed of 16 questions. RESULTS: A total of 165 responses were collected. In the case of minimally invasive hysterectomy for endometrial cancer, the routine use of UM was 42.7%. Of the 40.9% of surgeons who never used UM, 83.6% justified it with the risk of tumor spillage. When UM was used, surgeons mentioned reducing operating time and reducing complications in 67.0% and 59.8% of cases respectively as its main advantages. UM was set up without laparoscopic control in 54.6% of cases. In 47.4% of cases, the medical student was in charge of UM instrumentation. Tubal obliteration at the beginning of the procedure was performed systematically in 35.4% of cases. For 63.5% of UM users, the adjuvant treatment could be modified in case of uterine perforation. CONCLUSION: This survey confirms the heterogeneity of practices regarding the use of UM in endometrial cancer surgery. Prospective data on the benefit (reduction of surgical complications)/risk (impact on survival) balance are needed to recommend or not the use of this device.

FDG-PET/CT and Para-Aortic Staging in Endometrial Cancer. A French Multicentric Study.

BACKGROUND: FDG-PET/CT is a noninvasive examination that could be helpful for the management of endometrial cancer. The aim of this study was to evaluate the performance of FDG-PET/CT in assessing para-aortic lymph-node involvement in high-risk endometrial cancer. METHODS: We performed a retrospective multicenter study including all patients who had a high-risk endometrial cancer with a preoperative FDG-PET/CT and a para-aortic lymphadenectomy (PAL) between 2009 and 2019. The main objective was to evaluate the overall performance of FDG-PET/CT. The secondary objectives were to evaluate its performances according to the histological type and according to FDG-PET/CT date (before or after hysterectomy), and to compare its overall performance with that of the MRI scan. RESULTS: We included 200 patients from six different centers. After the false positive FDG-PET/CT was reread by nuclear physicians, FDG-PET/CT had a sensitivity of 61.8%, a specificity of 89.7%, a positive predictive value of 69.4%, a negative predictive value of 86.1%, and an AUC of 0.76. There were no statistically significant differences in the performances according to either histological type and or FDG-PET/CT date. The sensitivity of FDG-PET/CT was better than that of MRI (p < 0.01), but the specificity was not (p = 0.82). CONCLUSION: Currently, FDG-PET/CT alone cannot replace PAL for the lymph node evaluation of high-risk endometrial cancers. It seems essential to reread it in multidisciplinary meetings before validating the therapeutic management of patients, particularly in the case of isolated para-aortic involvement.

Assessment of Lymph Node Involvement with PET-CT in Advanced Epithelial Ovarian Cancer. A FRANCOGYN Group Study.

The objective of our study is to evaluate the diagnostic performance of positron emission tomography/computed tomography (PET-CT) for the assessment of lymph node involvement in advanced epithelial ovarian, fallopian tubal or peritoneal cancer (EOC). This was a retrospective, bicentric study. We included all patients over 18 years of age with a histological diagnosis of advanced EOC who had undergone PET-CT at the time of diagnosis or prior to cytoreduction surgery with pelvic or para-aortic lymphadenectomy. We included 145 patients with primary advanced EOC. The performance of PET-CT was calculated from the data of 63 patients. The sensitivity of PET-CT for preoperative lymph node evaluation was 26.7%, specificity was 90.9%, PPV was 72.7%, and NPV was 57.7%. The accuracy rate was 60.3%, and the false-negative rate was 34.9%. In the case of primary cytoreduction (n = 16), the sensitivity of PET-CT was 50%, specificity was 87.5%, PPV was 80%, and NPV was 63.6%. The accuracy rate was 68.8%, and the false negative rate was 25%. After neoadjuvant chemotherapy (n = 47), the sensitivity of PET-CT was 18.2%, specificity was 92%, PPV was 66.7%, and NPV was 56.1%. The accuracy rate was 57.5%, and the false negative rate was 38.3%. Due to its high specificity, the performance of a preoperative PET-CT scan could contribute to the de-escalation and reduction of lymphadenectomy in the surgical management of advanced EOC in a significant number of patients free of lymph node metastases.

[Impact of the LACC study. A SFOG survey]. / Impact de l'étude LACC. Une enquête de la SFOG.

INTRODUCTION: The LACC (Laparoscopic Approach to Cervical Cancer Trial) study, released in 2018, described oncological findings in favour of open surgery compared to the minimally invasive pathway in the management of early stage cervical cancers. Our aim was to assess the impact of this study on surgical practices in France. METHOD: Online questionnaire, consisting of 13 questions addressed to gynecology oncology french society (SFOG) surgeons. RESULTS: Forty questionnaires were collected. The median annual number of radical hysterectomy was 5 (0-20). Prior to the study, 92.5 % of cervical cancer patients had radical hysterectomy by minimally invasive surgery. In case of laparoscopy or robot, the uterine manipulator was used in 67.6 % and the colpotomy was performed intra-abdominally (78.4 %). After the LACC study, 60 % changed their practice. Open surgery was favored by 75 % of those who modified their practice. Among those continuing to perform minimally invasive surgeries, the manipulator and the intracorporeal colpotomy were discontinued. One-third of surgeons have changed their surgical practice for endometrial cancer in parallel. CONCLUSION: The results of the LACC study led to a change in surgical practices with an increase in open surgery and a stop in the use of the uterine manipulator and the laparoscopic/robotic intracorporeal colpotomy in the surgical management of early stage of cervical cancer.

Description of an initiation program to robotic in vivo gynecological surgery for junior surgeons.

INTRODUCTION: Most gynecological residents or junior surgeons do not practice nor experience robotic surgery due to lack of access during residency or poor knowledge about this growing surgical technology. This study evaluated the feasibility and safety of a 3-half-day experiencing and training session for robot-assisted gynecological surgery designed for residents and fellows. MATERIEL AND METHODS: This is a prospective, single-center observational study about a training course aimed at residents or fellows at the university teaching hospital of Limoges (France). It spreads over three consecutive half-days: one dedicated to simulation exercises involving the Da Vinci Skills Simulator© and the other two, to practice in two robot-assisted procedures with dual-console equipment supervised by a senior surgeon (as it is usually performed in a university teaching hospital). Complications during surgery, patient's medical records as well as the participants' performances during in vivo suturing acts were gathered. Feedback on the session was obtained with a questionnaire at the end of the course. RESULTS: Twelve sessions involving 24 patients operated on by 34 trainees from 16 different teaching university hospitals across the country took place. No conversion to laparotomy nor any major peri- or post-operative complication was reported. Time for stitching decreased significantly (p=.016) between the first and the second in vivo surgery. Use of the dual console was found helpful and most attendees (96.8%) would recommend this training session. CONCLUSION: We showed this training course with both simulation and in vivo surgery was feasible, safe and was a well-liked initiation program for robotic surgery.

Para-aortic Lymph Node Invasion in High-risk Endometrial Cancer: Performance of 18FDG PET-CT.

AIM: 18F-Fluorodeoxyglucose positron-emission tomography integrated with computed tomography (18FDG PET-CT) is a non-invasive examination that could be helpful for the management of endometrial cancer. This study investigated the performance of 18FDG PET-CT in assessing para-aortic (PA) lymph-node involvement in high-risk endometrial cancer. MATERIALS AND METHODS: This was a retrospective, single-center study carried out between 2009 and 2018. The inclusion criteria were high-risk and locally advanced type 1 or 2 endometrial cancer with 18FDG PET-CT before PA lymphadenectomy. RESULTS: During the study period, among 142 patients with high-risk endometrial cancer, 35 patients (24.6%) underwent 18FDG PET-CT followed by PA lymphadenectomy. In 25% of cases, PA lymphadenectomy was not performed due to the discovery of metastasis. 18FDG PET-CT had a sensitivity of 50%, a specificity of 100%, a positive predictive value of 100%, a negative predictive value of 75%, accuracy of 80% and an area under the curve of 0.75 for the evaluation of PA involvement. CONCLUSION: According to its high specificity in PA lymph-node evaluation, a positive PET scan might allow PA lymphadenectomy to be avoided.

The Key Role of Warm and Cold Ischemia in Uterus Transplantation: A Review.

Introduction: Uterus transplantation (UTx) is a promising treatment for uterine infertility that has resulted in several births since 2014. Ischemia is a key step in organ transplantation because it may lead to changes jeopardizing graft viability. Method: We performed a systematic review of animal and human studies relating to uterine ischemia. Results: We retained 64 studies published since 2000. There were 35 studies in animals, 24 in humans, and five literature reviews. Modest preliminary results in large animals and humans are limited but encouraging. In small animals, pregnancies have been reported to occur after 24 h of cold ischemia (CI). In ewes, uterine contractions have been detected after 24 h of CI. Furthermore, it has been shown in animals that uterine tolerance to CI and to warm ischemia (WI) can be increased by pharmacological products. In women, mean CI time in studies of births from uteri obtained from live donors was between 2 h 47 min and 6 h 20 min from a deceased donor; with only one birth in this case. Muscle contractions have also been demonstrated in myometrial samples from women, after six or more hours of CI. Conclusion: The uterus seems to be able to tolerate a prolonged period of CI, of at least six hours. Studies of the ischemia tolerance of the uterus and ways to improve it are essential for the development of UTx, particularly for procedures using grafts from deceased donors.
