A proof of concept that experience-based management of endometriosis can complement evidence-based guidelines.

Background: Management of endometriosis should be based on the best available evidence. The pyramid of evidence reflects unbiased observations analysed with traditional statistics. Evidence-based medicine (EBM) is the clinical interpretation of these data by experts. Unfortunately, traditional statistical inference can refute but cannot confirm a hypothesis and clinical experience is considered a personal opinion. Objectives: A proof of concept to document clinical experience by considering each diagnosis and treatment as an experiment with an outcome, which is used to update subsequent management. Materials and Methods: Experience and knowledge-based questions were answered on a 0 to 10 visual analogue scale (VAS) by surgery-oriented clinicians with experience of > 50 surgeries for endometriosis. Results: The answers reflect the collective clinical experience of managing >10.000 women with endometriosis. Experience-based management was overall comparable as approved by >75% of answers rated ≥ 8/10 VAS. Knowledge-based management was more variable, reflecting debated issues and differences between experts and non-experts. Conclusions: The collective experience-based management of those with endometriosis is similar for surgery-oriented clinicians. Results do not conflict with EBM and are a Bayesian prior, to be confirmed, refuted or updated by further observations. What is new?: Collective experience-based management can be measured and is more than a personal opinion. This might extend EBM trial results to the entire population and add data difficult to obtain in RCTs, such as many aspects of surgery.

[Simulation training for French obstetrics and gynecology residents: A national survey in 2022]. / Formation initiale par la simulation pour les internes français de gynécologie et obstétrique : état des lieux en 2022.

OBJECTIVES: To evaluate the use of simulation among French Obstetrics and Gynecology residency programs. METHODS: A survey was conducted with all 28 French residency program directors. The questionnaire covered equipment and human resources, training programs, types of simulation tools and time spent. RESULTS: Of the cities hosting a residency program, 93% (26/28) responded regarding equipment and human resources, and 75% (21/28) responded regarding training program details. All respondents declared having at least one structure dedicated to simulation. A formal training program was reported by 81% (21/26) of cities. This training program was mandatory in 73% of the cases. There was a median number of seven senior trainers involved, three of whom had received a specific training in medical education. Most of declared simulation activities concerned technical skills in obstetrics and surgery. Simulations to practice breaking bad news were offered by 62% (13/21) of cities. The median number of half-days spent annually on simulation training was 55 (IQR: 38-83). CONCLUSION: Simulation training is now widely available among French residency programs. There remains heterogeneity between centers regarding equipment, time spent and content of simulation curricula. The French College of Teachers of Gynecology and Obstetrics has proposed a roadmap for the content of simulation-based training based on the results of this survey. An inventory of all existing "train the trainers" simulation programs in France is also provided.

How to dissect the pelvic nerves: from microanatomy to surgical rules. An evidence-based clinical review.

Background: Advanced gynaecological procedures often include extensive pelvic dissections, with the nervous structures involved in the disease. Nerve-sparing and preservation is a key factor in reducing postoperative morbidity. Objectives: The goal of this review is to describe in detail the structure of the pelvic nerves and to gather information from other surgical specialties to give recommendations for safe nerve dissection applied in different gynaecological subspecialties. Materials and Methods: An extensive literature review was carried out in PubMed and Google Scholar. The search included articles concerning peripheral nerve anatomy, mechanisms of injury and different dissection techniques, with the most exhaustive being analysed for the review. Articles from different fields of medicine like orthopaedics, plastic surgery, maxillofacial surgery dealing with peripheral nerve injuries and repair have been reviewed. Results: The following review demonstrates the in-depth anatomy and mechanism of injury of the peripheral nerves, describes the different techniques for neurolysis and proposes some directions for safe nerve dissection. Conclusion: When performing complex gynaecological surgeries, the surgeon should avoid unnecessary nerve handling, apply nerve-sparing techniques whenever possible and use the new devices to preserve the nervous structures. Advanced gynaecological surgeries should be performed in specialised centres by expert surgeons with comprehensive knowledge in neuropelveology. What is new?: To our knowledge, this is the first article focused on peripheral nerves that collects data from such a wide range of specialties in order to propose the most comprehensive recommendations that could be applied in pelvic surgery.

Equipment failures in laparoscopic surgery: Causes and consequences.

OBJECTIVE: The aim of this study was to assess incidence, causes and consequences of equipment failures in a high volume, advanced endoscopic surgery department. METHODS: This is a prospectical observational single centre study between April and July of 2019 in the Gynecological surgery department of the Estaing University Hospital of Clermont-Ferrand, France. During the study period, 171 laparoscopies were observed. Data were collected real time by three supernumerary observers. RESULTS: In total, 66 (38.6%) laparoscopies were complicated by equipment failures. The bipolar cable and forceps accounted for 31% of the total amount of malfunctions in laparoscopy. Causes of malfunctions were in 45% due to the instrument per se and in 43% due to the incorrect combination of elements. Less commonly, the equipment was not available or a mismatched was reported. The total length of the surgery increased by 1.35% due to the malfunctions. Human error was identified in 50% of cases. No morbility, neither mortality was reported in this series; however we observed 34 malfunctions that could have led to serious consequences for the patients and 3 incidents induced a real consequence on the operation workflow. CONCLUSIONS: Equipment failure is a common event in endoscopy. On the opposite, time wasted for the malfunctions is low in laparoscopy, as it only accounts for 1.35% of the overall surgical time. Human decisions contributed to malfunctions in almost half of cases. This alarming finding may advise for intensification in training on instruments of the whole surgical team.

Evaluation of the laparoscopic component of GESEA Programme in two different groups: Obstetrics and Gynaecology Residents versus Participants in the Annual GESEA Diploma Course in Clermont Ferrand, France.

BACKGROUND: Structured laparoscopic training courses are important in surgical education. Different programmes have been proposed, but there is currently no evidence available comparing the performance of specialists versus residents in Obstetrics and Gynaecology at these courses. OBJECTIVE: To evaluate the impact of the laparoscopic component of Gynaecological Endoscopic Surgical Education and Assessment (GESEA) Training and Certification courses in two different populations. MATERIALS AND METHODS: Prospective cohort study. Two groups were analysed - participants of the Residents' Courses and participants of the Annual Francophone GESEA Diploma Course. Both groups were evaluated using the GESEA Level 1 laparoscopic standardised exercises and carried out in the International Center of Endoscopic Surgery (CICE), Clermont Ferrand, France in 2019. RESULTS: 57 French residents and 69 participants of the Annual GESEA Diploma were evaluated. The average age of participants in the Residents' Course was lower than those in the Annual Diploma Course (28.4±1.6 versus 35.2±8.0 years, p<0.001). Residents had higher previous experience in laparoscopic surgery (42% vs 36%, p< 0.001), in animal model surgery and in laparoscopic training box (67% vs 36% and 93% vs 67% respectively, p<0.001). Notable improvement was noted in both groups in the camera navigation exercise; first attempt 105±19 vs 117±9 seconds and final attempt 81±15 and 103±20 seconds respectively (p<0.001). CONCLUSIONS: Both groups improved significantly in most of the tests evaluated. French residents had better results in all evaluations, except in one aspect of the suture exercise (maintaining optimal results in performing the knot). After excluding the residents who attended the Annual Diploma Course, all the differences between both groups were statistically more significant.

Simulation and Training of Gynaecological Skills.

In order to offer our patients, the "state of the art" treatment in gynaecology, we need a structured teaching program for trainees concerning the gynaecological skills. In recent years, training and education in endoscopic surgery has been critically reviewed. Clinicians, both surgeons as gynaecologists who perform endoscopic surgery without proper training of the specific psychomotor skills, are at higher risk to increased patient morbidity and mortality. The traditional apprentice-tutor model is no longer valid for developing all skills necessary in gynaecological surgery, particularly in endoscopy. Endoscopic training should happen at both the theoretical and the practical skill level. The acquisition of the correct knowledge regarding general laparoscopy, hysteroscopy and standard level procedures is as important as learning the necessary psychomotor skills to successfully perform endoscopic manipulations. Training in the operating room can only start when it is proven that knowledge and skills are present. To learn and train total abdominal hysterectomy by laparotomy there are inexpensive simple models that can be used, which are easy to reproduce. The development, construction, cost, and utility of a low-cost and anatomically representative vaginal hysterectomy simulator also has been described. The complexity of modern surgery has increased the demands and challenges to surgical education and the quality control.

Management of endometriosis: CNGOF/HAS clinical practice guidelines - Short version.

First-line diagnostic investigations for endometriosis are physical examination and pelvic ultrasound. The second-line investigations are: targeted pelvic examination performed by an expert clinician, transvaginal ultrasound performed by an expert physician sonographer (radiologist or gynaecologist), and pelvic MRI. Management of endometriosis is recommended when the disease has a functional impact. Recommended first-line hormonal therapies for the management of endometriosis-related pain are combined hormonal contraceptives (CHCs) or the 52mg levonorgestrel-releasing intrauterine system (IUS). There is no evidence base on which to recommend systematic preoperative hormonal therapy solely to prevent surgical complications or facilitate surgery. After surgery for endometriosis, a CHC or 52mg levonorgestrel-releasing IUS is recommended as first-line treatment when pregnancy is not desired. In the event of failure of the initial treatment, recurrence, or multiorgan involvement, a multidisciplinary team meeting is recommended, involving physicians, surgeons and other professionals. A laparoscopic approach is recommended for surgical treatment of endometriosis. HRT can be offered to postmenopausal women who have undergone surgical treatment for endometriosis. Antigonadotrophic hormonal therapy is not recommended for patients with endometriosis and infertility to increase the chances of spontaneous pregnancy, including postoperatively. Fertility preservation options must be discussed with patients undergoing surgery for ovarian endometriomas.

Pelvic adhesions and fertility: Where are we in 2018?

Peritoneal adhesions remain a major public health problem despite the development of laparoscopy. The rules of microsurgery must be known and followed during any pelvic surgery, even in patients who no longer have a desire for pregnancy. Anti-adhesion products are numerous. All have interest, confirmed by anatomical studies showing a smaller extent or a lesser severity of adhesions associated with their use. No studies, however, show clinical benefit in terms of improved pain or postoperative fertility. Pneumoperitoneum parameters, humidification, and lower abdominal pressure should be optimized to limit peritoneal trauma. Peri-operative corticosteroids, whose benefit has been has been demonstrated in at least one randomized trial, should be systematically used.

[Nerve sparing techniques in deep endometriosis surgery to prevent urinary or digestive functional disorders: Techniques and results: CNGOF-HAS Endometriosis Guidelines]. / Les techniques de préservation nerveuse dans la chirurgie de l'endométriose profonde pour prévenir les séquelles fonctionnelles urinaires et digestives : modalités techniques et résultats. RPC Endométriose CNGOF-HAS.

OBJECTIVES: To evaluate the feasibility and functional urinary and digestive results of nerve sparing techniques in endometriosis surgery. METHODS: A research on the medline/pubmed database using specific keywords (nerve sparing, endometriosis, pelvic nerves) identified 7 publications among about 50 whose purpose was to describe the feasibility, the techniques and the functional results of nerve preservation in this indication. Among them there are: 2 uncontrolled retrospective studies, 3 prospective non-randomized studies, a meta-analysis and a review of the literature. RESULTS: Nerve preservation requires a perfect knowledge of the anatomy of the pelvic autonomic system. The laparoscopic approach is preferred by the different authors due to its anatomical advantage. The feasibility of this technique seems to be demonstrated despite certain limitations in the different studies and depending of the retroperitoneal extension of the lesions. When feasible, it is likely to significantly improve postoperative urinary function (urinary retention) compared to a conventional technique. It is observed no difference regarding digestive function. CONCLUSIONS: Nerve sparing in this indication is a technique the feasibility of which has been demonstrated and is subject to the topography and extent of the disease. In the absence of invasion or entrapment of pelvic autonomic nerves by endometriosis, this technique improves postoperative voiding function (NP3). During pelvic surgery for endometriosis, it is recommended to identify and preserve autonomic pelvic nerves whenever possible (GradeC).

[Management of endometriosis: CNGOF-HAS practice guidelines (short version)]. / Prise en charge de l'endométriose : recommandations pour la pratique clinique CNGOF-HAS (texte court).

First-line investigations to diagnose endometriosis are clinical examination and pelvic ultrasound. Second-line investigations include pelvic examination performed by a referent clinician, transvaginal ultrasound performed by a referent echographist, and pelvic MRI. It is recommended to treat endometriosis when it is symptomatic. First-line hormonal treatments recommended for the management of painful endometriosis are combined with hormonal contraceptives or levonorgestrel 52mg IUD. There is no evidence to recommend systematic preoperative hormonal therapy for the unique purpose of preventing the risk of surgical complications or facilitating surgery. After endometriosis surgery, combined hormonal contraceptives or levonorgestrel SIU 52mg are recommended as first-line therapy in the absence of desire of pregnancy. In case of initial treatment failure, recurrence, or multiple organ involvement by endometriosis, medico-surgical and multidisciplinary discussion is recommended. The laparoscopic approach is recommended for the surgical treatment of endometriosis. HRT may be offered in postmenopausal women operated for endometriosis. In case of infertility related to endometriosis, it is not recommended to prescribe anti-gonadotropic hormone therapy to increase the rate of spontaneous pregnancy, including postoperatively. The possibilities of fertility preservation should be discussed with the patient in case of surgery for ovarian endometrioma.

[Strategies and surgical management of endometriosis: CNGOF-HAS Endometriosis Guidelines]. / Synthèse des stratégies et prise en charge chirurgicale de l'endométriose, RPC Endométriose CNGOF-HAS.

The article presents French guidelines for surgical management of endometriosis. Surgical treatment is recommended for mild to moderate endometriosis, as it decreases pelvic painful complaints and increases the likelihood of postoperative conception in infertile patients (A). Surgery may be proposed in symptomatic patients with ovarian endometriomas which diameter exceeds 20mm. Cystectomy allows for better postoperative pregnancy rates when compared to ablation using bipolar current, as well as for lower recurrences rates when compared to ablation using bipolar current or CO2 laser. Ablation of ovarian endometriomas using bipolar current is not recommended (B). Surgery may be employed in patients with deep endometriosis infiltrating the colon and the rectum, with good impact on painful complaints and postoperative conception. In these patients, laparoscopic route increases the likelihood of postoperative spontaneous conception when compared to open route. When compared to conservative rectal procedures (shaving or disc excision), segmental colorectal resection increases the risk of postoperative stenosis, requiring additional endoscopic or surgical procedures. In large deep endometriosis infiltrating the rectum (>20mm length of bowel infiltration), conservative rectal procedures do not improve postoperative digestive function when compared to segmental resection. In patients with bowel anastomosis, placing anti-adhesion agents on contact with bowel suture is not recommended, due to higher risk of bowel fistula (C). Various other recommendations are proposed in the text, however, they are based on studies with low level of evidence.

Development of an ovine model for training in vaginal surgery for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: This aim of this study was to evaluate the feasibility and usefulness of an ovine model for training in vaginal surgery. METHODS: Four senior urogynaecological surgeons and five residents attended five sessions of vaginal surgery for pelvic organ prolapse (POP) in five old multiparous female sheep. Urogynaecological examinations were performed and measurements similar to the POP-Q classification in humans were obtained. Standard POP surgical procedures with and without mesh were performed. A pelvic CT scan was done on one animal and the structures were compared with the pelvic structures in a woman. After the feasibility of vaginal surgery had been established in three cadavers, surgery was performed in two living animals under general anaesthesia and was followed by laparoscopy to explore the internal pelvic anatomy. RESULTS: We found anatomic similarities in the vaginal and pelvic structures between sheep and women. After caudal traction on the cervix, all five sheep had significant POP of stage 3 or 4. We proved the feasibility of all types of vaginal surgery in this animal model: traditional anterior and posterior repair, apex fixation and anterior wall repair with mesh. The video shows the internal pelvic anatomy and different vaginal procedures. CONCLUSION: This study showed that training in vaginal surgery for POP is feasible and useful in an animal model, the ewe, that has vaginal and pelvic structures very similar to those in women.

[Interest of complex tasks on laparoscopic virtual reality simulator]. / Intérêt des tâches complexes sur simulateur de réalité virtuelle laparoscopique.

OBJECTIVES: The purpose of this study was to assess the contribution of complex tasks on virtual reality simulator (VRS) for novice surgeons in laparoscopy learning. MATERIALS AND METHODS: Fifty-five medical students were prospectively randomized in two groups (A: basic skills, n=28 and B: basic and complex skills, n=27) and then trained during two sessions on VRS. Evaluations took place before and after each training. These evaluations consisted of the achievement of an intracorporeal suture, recorded on video, with the left then with the right hand. Two independent experts evaluated those gestures blindly. RESULTS: A significant progression in terms of times and technical scores was observed in both groups between the first and the last evaluations (P between 0.001 and 0.04). Students in group B improved slower and longer than those in group A. However, left and right hands results confused did not highlight significant differences between the two groups. At the third session, the first hand to train is significantly faster in group B than in group A (P=0.04). CONCLUSION: This study found only a late and minimal impact of complex skills to reduce the execution time of intracorporeal suture. It also showed an slower and longer overall progression for those who use them compared to subjects using basic skills only.

[Long-term complication of laparoscopic uterine morcellation: iatrogenic parasitic myomas]. / Complication à long terme du morcellement utérin par voie cœlioscopique: les myomes parasitiques iatrogènes.

OBJECTIVES: Identify parasitic myomas following uterine laparoscopic morcellation and describe the circumstances of diagnosis, management, potential consequences and possible preventive measures. METHODS: Retrospective study of observed cases in a university hospital between 2000 and 2012 and review of the literature. RESULTS: Five cases were identified in our department. Pelvic pain was the main symptom in three patients while one was asymptomatic and one consulted for a cystocele. The average time to diagnosis was 88 months (3-192). Surgical removal was performed in four cases by laparoscopy and vaginally for one case. Histological examination showed typical leiomyomas, but in one case, an atypical leiomyoma with limited experience for a typical primary lesion. In the literature, there are about 50 cases. One required a bowel resection and for another one, after subtotal hysterectomy, histological examination showed complex atypical endometrial hyperplasia for normal endometrium initially. CONCLUSIONS: This study should draw the attention of laparoscopic surgeon. It emphasizes, beyond a potential reoperation, a risk of atypical histological secondary processing. Surgical resection should be discussed even in case of asymptomatic lesions.

[Laparoendoscopic single-site surgery in gynecology: the situation in 2013]. / La laparoscopie par incision unique en gynécologie : état des lieux en 2013.

BACKGROUND: Single-incision laparoscopic surgery (SILS) is a recent technic of minimally invasive surgery that arouses a growing interest due to its potential benefits in terms of pain and cosmetic. However, in gynecology as well as in other surgical specialties, preliminary results seem to be controversial. Its feasibility and interest by comparison with conventional laparoscopy (CL) have not been confirmed by randomized multicenter studies. OBJECTIVES: Compare in gynecological surgery, feasibility and surgical outcomes (conversion rate and complications, postoperative pain, duration of surgery, length of hospital stay, appearance and cost) between SILS and CL. PATIENTS AND METHODS: For this, a review of the literature from a PUBMED and Medline databases was conducted. The clinical cases and series with fewer than 10 patients were excluded. Eligible data were compared and analyzed. RESULTS: A total of 46 studies including five prospective randomized were studied in gynecology. Conversion rates and complications appear identical to those of the CL. The learning curve is also comparable. The technique is not standardized and some ergonomic problems are described. Operating time and duration of hospitalization seems to be comparable. The postoperative pain assessment found conflicting results. The cosmetic results are in favor of the single incision laparoscopy. Finally, the cost is higher. CONCLUSIONS: According to the literature, the single incision laparoscopy seems feasible and safe, with better cosmetic results. But the cost is increased and associated with no benefit in terms of pain, operating time and duration of hospitalization. Beyond cosmetics results, further randomized studies are needed to identify a possible benefit.

[Ovarian drilling by fertiloscopy: feasibility, results and predictive values]. / Drilling ovarien par fertiloscopie : faisabilité, résultats et valeurs prédictives.

OBJECTIVES: The aims of this study were to assess the effectiveness of the ovarian drilling, compare the techniques by fertiloscopy or by laparoscopy, and search for prognostic factors of success. PATIENTS AND METHODS: This retrospective study focused on 154 ovarian drilling carried out between June 1998 and December 2010 where the drilling has been proposed after failure of the clomifene and before stimulation by FSH among PCOS patients. RESULTS: The post-drilling ovulation rate is 62%. The spontaneous on-going pregnancy rate is 31% and the total pregnancy rate scalable including secondary stimulation is 58%. No significant difference was found between laparoscopy and the fertiloscopy. The peroperative complications in fertiloscopy were more frequent but without consequences and 20% of the fertiloscopy had to be converted to laparoscopy, half of them for complications and half of them for technical difficulties. The only found preoperative predictors of success are an euthyroidy that increases the chances of pregnancy in general (including the side stimulation) and a lower FSH levels. However, it appears that the chances of pregnancy in FSH stimulation are dramatically decreased if the drilling did not induce ovulation versus the cases where it induced ovulation but no pregnancy (28.8% versus 58.1%, P<0.003). DISCUSSION AND CONCLUSION: Fertiloscopy results are comparable with those of laparoscopy, which suggests an advantage to this technique in terms of cost, comfort, and length of hospital stay. No usable in practice patient selection criteria could be highlighted. The study suggests that the absence of ovulation after drilling may be a direct indication for IVF.

[Interest of a structured laparoscopy training in a simulation center: survey of resident's point of view]. / Intérêt d'un enseignement structuré de la cœlioscopie en centre de simulation : enquête d'opinion auprès des internes.

OBJECTIVE: Assess residents satisfaction within their participation to a short and structured training to laparoscopy, gathering theoretical and practical issues. METHODS: This course was divided in two periods of 3days including an individual prospective evaluation. For each period, the residents have answered to three questionnaires trying to evaluate their experience in laparoscopy and their short term and medium term satisfaction. RESULTS: Three hundred residents from different French university hospitals have been involved in this study. After 4years, half of them were not satisfied with their chirurgical studies. Thirty-seven percent of them never attended to any surgical procedure as main operator. The training course has answered to their expectation for 95% of the residents and 85% said they now feel more confident about laparoscopy then before. According to 76% of them, it should be a compulsory and systematic training course and for 75%, they should be tested regarding their laparoscopy skills level during the resident studies period. The training on animals is the more efficient for 86% of them. CONCLUSIONS: Due to the increasing number of residents and to the legal time for rest, the time spent in the operative room has decreased. People also do not accept easily the training made on true patients. Intensive and tested training are useful and answer to residents needs. They could be systematically integrated in their global curriculum.
