Apport d’un simulateur d’hystéroscopie virtuelle dans l’apprentissage de la résection hystéroscopique de fibrome

OBJECTIVESnUterine myomas are a frequent pathology affecting 20% of women of reproductive age. Myomas induce abnormal uterine bleeding, pelvic pain and increase the risk of infertility and obstetrical complications. Symptomatic sub-mucosal myomas are classically treated by hysteroscopic resection. Simulation is a method of education and training. It could improve quality and security of cares. The aim of this study is to assess the interest of a hysteroscopic simulator for the resection of myoma by novice surgeons.nnnMETHODSnTwenty medical students were recruited, in a prospective study, in august 2014. The virtual-reality simulator VirtaMed HystSim™ (VirtaMed AG, Zurich, Switzerland) was used to perform the hysteroscopic training. All students received a short demonstration of myoma resection. The practice consists of a submucous myoma type 0 resection. The procedure and the evaluation were performed before and after a specific training in hysteroscopic resection of sixty minutes long. The main outcome criteria were time for the resection before and after training. The second criteria were fluid quantity used, number of contact between optic and uterine cavity and uterine perforation.nnnRESULTSnTwenty students aged from 22 to 24 years were included. The time for the procedure was significantly reduced after training (170s versus 335s, P<0.01). There is the same for fluid quantity used (335 mL versus 717mL, P<0.01) and the number of contact between optic and uterine cavity (0.2 contact versus 3, P=0.012). No perforation occurred in the simulation.nnnCONCLUSIONnThe results suggest that hysteroscopic simulator enhances and facilitates hysteroscopic resection for novice surgeons.

The impact of manual rotation of the occiput posterior position on spontaneous vaginal delivery rate: study protocol for a randomized clinical trial (RMOS)

BackgroundThe frequency of posterior presentations (occiput of the fetus towards the sacrum of the mother) in labor is approximately 20% and, of this, 5% remain posterior until the end of labor. These posterior presentations are associated with higher rates of cesarean section and instrumental delivery. Manual rotation of a posterior position in order to rotate the fetus to an anterior position has been proposed in order to reduce the rate of instrumental fetal delivery. No randomized study has compared the efficacy of this procedure to expectant management. We therefore propose a monocentric, interventional, randomized, prospective study to show the superiority of vaginal delivery rates using the manual rotation of the posterior position at full dilation over expectant management.MethodsUltrasound imaging of the presentation will be performed at full dilation on all the singleton pregnancies for which a clinical suspicion of a posterior position was raised at more than 37 weeks’ gestation (WG). In the event of an ultrasound confirming a posterior position, the patient will be randomized into an experimental group (manual rotation) or a control group (expectative management with no rotation). For a power of 90% and the hypothesis that vaginal deliveries will increase by 20%, (10% of patients lost to follow-up) 238 patients will need to be included in the study. The primary endpoint will be the rate of spontaneous vaginal deliveries (expected rate without rotation: 60%). The secondary endpoints will be the rate of fetal extractions (cesarean or instrumental) and the maternal and fetal morbidity and mortality rates. The intent-to-treat study will be conducted over 24 months. Recruitment started in February 2017.To achieve the primary objective, we will perform a test comparing the number of spontaneous vaginal deliveries in the two groups using Pearson’s chi-squared test (provided that the conditions for using this test are satisfactory in terms of numbers). In the event that this test cannot be performed, we will use Fisher’s exact test.DiscussionGiven that the efficacy of manual rotation has not been proven with a high level of evidence, the practice of this technique is not systematically recommended by scholarly societies and is, therefore, rarely performed by obstetric gynecologists.If our hypothesis regarding the superiority of manual rotation is confirmed, our study will help change delivery practices in cases of posterior fetal position. An increase in the rates of vaginal delivery will help decrease the short- and long-term rates of morbidity and mortality following cesarean section.Manual rotation is a simple and effective method with a success rate of almost 90%. Several preliminary studies have shown that manual rotation is associated with reduced rates for fetal extraction and maternal complications: Shaffer has shown that the cesarean section rate is lower in patients for whom a manual rotation is performed successfully (2%) with a 9% rate of cesarean sections when manual rotation is performed versus 41% when it is not performed. Le Ray has shown that manual rotation significantly reduces vaginal delivery rates via fetal extraction (23.2% vs 38.7%, p < 0.01). However, manual rotation is not systematically performed due to the absence of proof of its efficacy in retrospective studies and quasi-experimental before/after studies.Trial registrationClinicalTrials.gov, Identifier: NCT03009435.

Effect of the use of a video tutorial in addition to simulation in learning the maneuvers for shoulder dystocia

The development of video tutorials is flourishing and may make it possible to maintain knowledge learned during instruction with simulation. The aim of this study was to assess the effect of adding a video tutorial to a lecture and simulation for learning the maneuvers and protocol for the management of shoulder dystocia. Student midwives and medical students attended a lecture class including instruction about maneuvers and a presentation of an algorithm for the management of shoulder dystocia. They were randomized into two groups. The video group was reminded every two weeks to watch a short tutorial. The control group was reminded to consult the slide show. At the end of two months, they were evaluated by graders. The practice, theory, and global scores of the students in the video group were significantly higher than those of the students in the control group (14.8 vs. 10.4; 5.6 vs. 3.4; and 9.3 vs. 7.0, P<0.001). The scores for the video group improved at the second simulation session, compared with the first (14.8 vs. 9.9; 5.6 vs. 2.9; and 9.3 vs. 7, P<0.001). The addition of a video tutorial improved learning compared to a standard lecture and simulation session alone.

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.

Dystocie des épaules : évaluation de la qualité de la retranscription dans les dossiers médicaux

OBJECTIVEnShoulder dystocia is a rare obstetrical event and potentially serious. Apart from possible psychological implications, it may be responsible for maternal (haemorrhage and perineal tear) and neonatal complications (brachial plexus) leading to complaints and even lawsuits. The transcription of this event in medical files is essential as it is a reflection of the work in an emergency. It allows the obstetrician to defend him in case of trial. Our objective was to assess the quality of the transcription of shoulder dystocia situations in medical files.nnnMETHODnRetrospective chart study conducted in a university hospital with maternity typexa0III. The primary objective was the rate of comprehensive records (name maneuvers and order of maneuvers of the anterior shoulder hand, time between the expulsion of the head and body, Apgar score).nnnRESULTSnBetween 2007 and 2015, 54xa0cases of shoulder dystocia requiring a second line maneuver after vaginal delivery (Wood and/or Jacquemier) were included. In all, 98.2% of the files were incomplete. The maneuvers and their order were noted in 100% of cases. However, the operation was not correctly described in 16.7% of cases. The anterior shoulder was noted in 16.7% of cases. The time between the expulsion of the head and the body was noted in one single files. Neither broken collarbone nor brachial plexus were observed.nnnCONCLUSIONnTo improve the management of dystocia shoulder and transcription of data in files, simulation sessions and the creation of a standardized form would be needed.

Formation des internes et jeunes assistants de gynécologie-obstétrique en statique pelvienne en France

OBJECTIVESnFor the treatment of prolapse, the vaginal route is less standardized than laparoscopy and seems abandoned by younger doctors. Our objectives were to evaluate the surgical experience of resident and youth gynecology and obstetrics assistants in pelviperineology and the level of confidence and mastery of the different surgical treatment of pelvic.nnnMETHODSnAn anonymous questionnaire sent via an Internet platform interviewing residents and young assistants of gynecology and obstetrics (promotion 2005 to 2010) in France on their surgical training in pelviperineology.nnnRESULTSnTwenty-nine percent (208/724) of the persons contacted responded with two thirds of residents and one third of young assistants, all regions of France were represented. Sixty-four percent of respondents wanted to favor a surgical career. The laparoscopic sacrocolpopexy was declared to be the best method mastered while residents and young assistants reported being more often leading operator in vaginal techniques during their medical training.nnnCONCLUSIONnSurgical practice during medical training of resident and young assistants did not seem associated with declared mastery level of technique. Different clinical surgical practice training techniques such as simulation, cadaveric study, movies on surgical technics may also improve the level of confidence and mastery of young doctors for surgical techniques.
