RESUMO
INTRODUCTION: After incomplete healing of the uterine cesarean section scar, a niche can be observed; 24% of the women develop large niches with a residual myometrial thickness <3 mm. In these cases a laparoscopic resection is possible. The effect of this new treatment on fertility outcome is not known yet. This paper describes reproductive outcomes 2 years after a laparoscopic niche resection and compares women with or without secondary infertility at baseline. MATERIAL AND METHODS: A prospective cohort study was performed, with consecutive inclusion of women between 2011 and 2019. Women with a niche in the uterine cesarean scar, with a residual myometrial thickness of <3 mm and with a desire to become pregnant, were scheduled to undergo a laparoscopic niche resection because of one or more of the following problems (1) postmenstrual spotting; (2) midcycle intrauterine fluid accumulation diagnosed during the fertility workup or (3) difficulties with a previous embryo transfer and preferring a surgical therapy. The study is registered in the ISRCTN register (ref. no. ISRCTN02271575) on April 23, 2013. RESULTS: There were 133 (62%) women included with a desire to become pregnant, 88 with secondary infertility. In all, 83 had an ongoing pregnancy at the 2-year follow-up. The ongoing pregnancy rate in patients with previous fertility problems was 60.2% compared with 66.7% in patients without infertility (odds ratio [OR] 0.68, 95% confidence interval [CI] 0.32-1.7). The OR for live births was 0.57 (95% CI 0.02-1.2). Overall, 8.3% of the pregnancies resulted in miscarriages by the 2-year follow-up. CONCLUSIONS: The reproductive outcomes in women with and without previous fertility problems undergoing resection of a large niche are very promising and quite comparable in both groups. These results suggest, but do not prove, a beneficial effect of this therapy for these indications. The results support the design of future randomized controlled trials to evaluate the effect of niche resection vs expectant management to assess its additional value in women with or without fertility problems who desire pregnancy.

BACKGROUND: Intrauterine adhesions (IUAs) are one of the main reproductive system diseases in women worldwide. Fusion between the injured opposing walls leads to partial-to-complete obliteration of the cavity and/or cervical canal. The main clinical manifestations in case of IUAs are menstrual disturbances, cyclic pain and reproductive disorders. The reproductive outcomes of women with IUAs remain limited and inefficient compared to women without IUAs, even after adhesiolysis. An exact understanding of the underlying mechanisms and processes to explain the compromised reproductive performance and outcomes in case of IUAs are lacking. METHODS: A systematic literature review of MEDLINE-PubMed (1966 to January 2022) and EMBASE (1974 to January 2022) was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies were included if they reported underlying causes, related mechanisms and processes to explain the association between IUAs and impaired reproductive performance, pregnancy and obstetric complications. RESULTS: After an extensive review of the literature, 58 articles were identified reporting underlying mechanisms to explain the association between IUAs and impaired fertility. Intrauterine scarring influences the process of fertilization, reproductive performance and ultimately reproductive outcome. IUAs can disturb the cervico-utero-tubal sperm transport and result in an avascular and unresponsive endometrium with decreased receptivity and thickness. Abnormal decidualization and abnormal trophoblastic infiltration leads to placental attachment disorders. Moreover, the risk for premature delivery, intrauterine fetal growth restriction and fetal anomalies is increased in case of IUAs. CONCLUSION: The impact of IUAs on reproductive performance, even after adhesiolysis, is becoming more apparent. The postulated mechanisms to explain the association are related to sperm transport, embryo implantation and placentation. Prevention, by preserving the basal layer of the endometrium is essential. Effective and evidence-based strategies for the prevention of endometrial injury and formation of IUAs, are urgently needed.

STUDY QUESTION: Are the long-term reproductive outcomes following recurrent dilatation and curettage (D&C) for miscarriage in women with identified and treated intrauterine adhesions (IUAs) comparable to women without IUAs. SUMMARY ANSWER: Reproductive outcomes in women with identified and treated IUAs following recurrent D&C for miscarriage are impaired compared to women without IUAs; fewer ongoing pregnancies and live births are achieved with a prolonged time to a live birth. WHAT IS KNOWN ALREADY: The Prevention of Adhesions Post Abortion (PAPA) study showed that application of auto-crosslinked hyaluronic acid (ACP) gel, an absorbable barrier in women undergoing recurrent D&C for miscarriage resulted in a lower rate of IUAs, 13% versus 31% (relative risk 0.43, 95% CI 0.22 to 0.83), lower mean adhesion score and significant less moderate to severe IUAs. It is unclear what the impact is of IUAs on long-term reproductive performance. STUDY DESIGN, SIZE, DURATION: This was a follow-up of the PAPA study, a multicenter randomized controlled trial evaluating the application of ACP gel in women undergoing recurrent D&C for miscarriage. All included women received a diagnostic hysteroscopy 8-12 weeks after randomization to evaluate the uterine cavity and for adhesiolysis if IUAs were present. Here, we present the reproductive outcomes in women with identified and treated IUAs versus women without IUAs, 46 months after randomization. PARTICIPANTS/MATERIALS, SETTING, METHODS: Between December 2011 and July 2015, 152 women with a first-trimester miscarriage with at least one previous D&C, were randomized for D&C alone or D&C with immediate intrauterine application of ACP gel. Participants were approached at least 30 months after randomization to evaluate reproductive performance, obstetric and neonatal outcomes and cycle characteristics. Additionally, the medical files of all participants were reviewed. Main outcome was ongoing pregnancy. Outcomes of subsequent pregnancies, time to conception and time to live birth were also recorded. MAIN RESULTS AND THE ROLE OF CHANCE: In women pursuing a pregnancy, 14/24 (58%) ongoing pregnancies were recorded in women with identified and treated IUAs versus 80/89 (90%) ongoing pregnancies in women without IUAs odds ratio (OR) 0.18 (95% CI 0.06 to 0.50, P-value <0.001). Documented live birth was also lower in women with IUAs; 13/24 (54%) with versus 75/89 (84%) without IUAs, OR 0.22 (95% CI: 0.08 to-0.59, P-value 0.004). The median time to conception was 7 months in women with identified and treated IUAs versus 5 months in women without IUAs (hazard ratio (HR) 0.84 (95% CI 0.54 to 1.33)) and time to conception leading to a live birth 15 months versus 5.0 months (HR 0.54 (95% CI: 0.30 to 0.97)). In women with identified and treated IUAs, premature deliveries were recorded in 3/16 (19%) versus 4/88 (5%) in women without IUAs, P-value 0.01. Complications were recorded in respectively 12/16 (75%) versus 26/88 (30%), P-value 0.001. No differences were recorded in mean birth weight between the groups. LIMITATIONS, REASONS FOR CAUTION: In the original PAPA study, randomization was applied for ACP gel application. Comparing women with and without IUAs is not in line with the randomization and therefore confounding of the results cannot be excluded. IUAs, if visible during routine hysteroscopy after randomization were removed as part of the study protocol; the influence of IUAs on reproductive outcome may therefore be underestimated. Women undergoing a recurrent D&C for miscarriage were included, a specific group likely to generate clinically significant adhesions. The findings should therefore not be generalized to all women undergoing D&C for miscarriage. WIDER IMPLICATIONS OF THE FINDINGS: As IUAs have an impact on reproductive performance, even after hysteroscopic adhesiolysis, primary prevention is essential. Expectative and medical management should therefore be considered as serious alternatives for D&C in women with a miscarriage. In case D&C is necessary, application of ACP gel should be considered. STUDY FUNDING/COMPETING INTEREST(S): The original PAPA study (NTR 3120) was an investigator initiated study that was funded by the Foundation for scientific investigation in Obstetrics and Gynaecology of the Saint Lucas Andreas Hospital (currently renamed OLVG Oost), SWOGA. The syringes containing ACP gel were received from Anika Therapeutics, the manufacturer of Hyalobarrier® Gel Endo. The current follow-up study was also an investigator-initiated study without funding. The funder and sponsor had no role in the design of this follow-up study, data collection, data analysis, data interpretation, trial design, patient recruitment, writing of the report or any aspect pertinent to the study. ABH, RAL, JAFH and JWRT have no conflict to declare. HAMB reports being a member of safety board research Womed. TRIAL REGISTRATION NUMBER: Netherlands Trial Register NTR 3120.

OBJECTIVES: To investigate the accuracy and reliability of 3-dimensional (3D) transvaginal sonography in classifying submucous fibroids using the International Federation of Gynecology and Obstetrics PALM-COEIN (polyp, adenomyosis, leiomyoma, malignancy and hyperplasia, coagulopathy, ovulatory dysfunction, endometrial, iatrogenic, and not yet classified) classification and protrusion (percent) compared to 2-dimensional (2D) transvaginal sonography, 2D saline infusion sonography, and 3D saline infusion sonography, using hysteroscopy as a reference test. METHODS: A prospective cohort pilot study was performed among 14 consecutive patients undergoing hysteroscopic surgery, preceded by routine sonography (2D transvaginal sonography, 2D saline infusion sonography, 3D transvaginal sonography, and 3D saline infusion sonography). RESULTS: The intraclass correlation coefficient (ICC) for 2D transvaginal sonography versus hysteroscopy was 0.69 (95% confidence interval [CI], 0.06, 0.90) compared to 0.94 (95% CI, 0.83, 0.98) for 2D saline infusion sonography. The ICCs for 3D transvaginal sonography versus hysteroscopy were 0.69 (95% CI, 0.03, 0.90 [investigator A]) and 0.55 (95% CI, -0.48, 0.86 [investigator B]). The ICCs for 3D saline infusion sonography versus hysteroscopy were 0.94 (95% CI, 0.81, 0.98 [investigator A]) and 0.87 (95% CI, 0.60, 0.96 [investigator B]). Interobserver agreement of 3D transvaginal sonography was 0.81 (95% CI, 0.43, 0.94) compared to 0.86 (95% CI, 0.56, 0.96) for 3D saline infusion sonography. CONCLUSIONS: In these preliminary data, 3D transvaginal sonography was not as accurate as 2D or 3D saline infusion sonography and was not more accurate than 2D transvaginal sonography. There was moderate interobserver agreement for 3D transvaginal sonography. There might be room for improvement, as 3D transvaginal sonography is more accurate when endometrial thickness increases. Further study is warranted to evaluate in which patients saline infusion sonography eventually can be obviated.

AIM: To study changes in a ceasarean section (CS) scar during the first year after a CS using gel installation sonography (GIS). METHODS: Proof-of-concept study, prospective cohort study. Twenty women who delivered by their first CS were evaluated by both transvaginal sonography and GIS 2 months and 1 year after CS. A niche was defined as an anechogenic space at the uterine caesarean scar with a depth >2 mm. The primary outcome was any change in the thickness of the residual myometrium (RMT) as evaluated by GIS. RESULTS: Mean RMT changed in time from 11.9 mm at 2 months to 6.5 mm at 12 months after the CS (p < 0.001). Niche prevalence did not change. The adjacent myometrium (AM) reduced from 15 to 12.4 mm (p = 0.04). The ratio between RMT and AM with GIS decreased from 0.80 at 2 months to 0.54 at 12 months (p = 0.002). CONCLUSION: RMT thickness, the adjacent myometium and the ratio between the RMT and AM reduces from 2 to 12 months after a CS. The prevalence did not change. This needs to be taken into account when deciding on the timing of niche measurement and the interpretation of the RMT.

BACKGROUND: Focal abnormalities most commonly acquired within the uterine cavity include endometrial polyps (arising from the endometrium) and submucous fibroids (arising from the myometrium). These benign abnormalities can cause several problems, including abnormal uterine bleeding (AUB) and subfertility. Two-dimensional saline infusion sonography (2D SIS) is a minimally invasive test that can be used to diagnose these pathologies, but it is less accurate than hysteroscopy, which is a more invasive procedure by which an endoscope allows direct visualisation of the uterine cavity. Three-dimensional (3D) SIS appears to enhance sonographic visualisation within the uterine cavity, thereby offering a potentially more accurate minimally invasive diagnostic test. OBJECTIVES: Primary objectives ⢠To evaluate the diagnostic accuracy of 3D SIS (index test 1) compared with 2D SIS for the diagnosis of focally growing lesions (presence or not) in women with AUB or subfertility, with hysteroscopy performed as the reference test. ⢠To evaluate the diagnostic accuracy of 2D+3D SIS (index test 2) compared with 2D SIS for the diagnosis of focally growing lesions (presence or not) in women with AUB or subfertility, with hysteroscopy performed as the reference test. In this case, any abnormality on either modality was regarded as a positive result ('OR' approach). Secondary objectives ⢠To evaluate the diagnostic accuracy of 3D SIS (index test 1) compared with 2D SIS according to type of abnormality and discrimination between uterine polyps and submucous fibroids in women with AUB or subfertility, with hysteroscopy and histology used as the reference.⢠To evaluate the diagnostic accuracy of 2D+3D SIS (index test 2) compared with 2D SIS according to type of abnormality and discrimination between uterine polyps and submucous fibroids in women with AUB or subfertility, with hysteroscopy and histology used as the reference. SEARCH METHODS: We searched the following databases: Cochrane Central Register of Studies Online (CENTRAL CRSO), MEDLINE, Embase, PubMed, Cochrane Gynaecology and Fertility Group (CGF) Specialised Register and CGFG Diagnostic Test Accuracy (DTA) Specialised Register, clinicaltrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). Screening reference lists of appropriate studies was also performed. We screened for eligibility all studies identified from inception until March 2016. We performed searches with no date or language restrictions. SELECTION CRITERIA: The population of interest consisted of premenopausal women with AUB or subfertility and postmenopausal women with AUB. Diagnostic test accuracy studies, randomised controlled trials (RCTs) and prospective cohort studies were eligible for inclusion if they evaluated the accuracy of both 2D SIS and 3D SIS for the diagnosis of acquired intracavitary abnormalities with hysteroscopy used as the reference standard. In light of the lack of data for 3D SIS, we also included studies that evaluated the accuracy of 3D SIS alone. DATA COLLECTION AND ANALYSIS: Two review authors read all potentially eligible references after performing a first screening by title and abstract (LLN and FJRH). They independently extracted data to construct 2×2 tables from eligible studies and assessed studies for methodological quality using the QUADAS-2 tool (revised tool for quality assessment of diagnostic accuracy studies). To describe and visually present results, we produced in RevMan forest plots showing pairs of sensitivity and specificity together with 95% confidence intervals from each study, as well as raw receiver operating characteristic (ROC) plots. We displayed paired analyses in an ROC plot by linking sensitivity-specificity pairs from each study by using a dashed line. To compare 3D SIS versus 2D SIS, we restricted analyses to studies that provided 2×2 tables for both tests and used the bivariate meta-analysis of sensitivity and specificity. MAIN RESULTS: Thirteen studies (1053 women) reported the accuracy of 3D SIS for focal uterine abnormalities; 11 of these (846 women) were suitable for meta-analysis, and eight reported accuracy according to the type of focal abnormality. The design of the included studies seems applicable. The main problem involving the quality of included studies is insufficient reporting of study methods, resulting in unclear risk of bias for several of the quality domains assessed. Therefore, we considered the overall quality of the evidence as low. The summary estimate (11 studies reporting absence or presence of abnormality at 3D SIS) for sensitivity was 94.5% (95% confidence interval (CI) 90.6% to 96.9%) and for specificity 99.4% (95% CI 96.2% to 99.9%). Meta-analysis of the eight studies (N = 716) directly comparing 2D SIS versus 3D SIS showed summary sensitivity of 96.9% (95% CI 91.9% to 98.8%) and summary specificity of 99.5% (95% CI 96.1% to 100%) for 3D SIS. For 2D SIS, summary sensitivity was 90.9% (95% CI 81.2% to 95.8%) and summary specificity was 96.3% (95% CI 86.1% to 99.1%). The difference in accuracy between 2D SIS and 3D SIS was non-significant (P values of 0.07 for sensitivity and 0.10 for specificity). AUTHORS' CONCLUSIONS: Low-quality evidence suggests that 3D SIS may be very accurate in detecting intracavitary abnormalities. Meta-analysis revealed no statistically significant differences between 2D SIS and 3D SIS. Summary sensitivity and summary specificity are higher for 3D SIS, but margins of improvement are limited because 2D SIS is already very accurate. When the technology and appropriate expertise are available, 3D SIS offers an alternative to 2D SIS. Both 2D SIS and 3D SIS should be considered alternatives to diagnostic hysteroscopy when intracavitary pathology is suspected in subfertile women and in those with abnormal uterine bleeding.

OBJECTIVES: Termination of pregnancy (TOP) is one of the most performed interventions in women worldwide: approximately one in three women will have at least one TOP in their reproductive life. Intrauterine adhesions (IUAs) have been reported as a possible complication after TOP, but their prevalence has not been established, as women are not routinely evaluated. IUAs are associated with menstrual disturbances, infertility and obstetric complications. METHODS: We searched Ovid MEDLINE, Ovid EMBASE and CENTRAL from inception until November 2015 for studies evaluating women following TOP. We selected studies in which women were evaluated consecutively, independently of symptoms, by hysteroscopy or hysterosalpingography (HSG), for the presence of IUAs. RESULTS: After an extensive review of the literature, no studies were found that evaluated women after medical TOP and no randomised trials following surgical TOP. Only two prospective cohort studies were identified. In the first, IUAs were detected in 21.2% of women evaluated by hysteroscopy following first trimester surgical TOP; adhesions were moderate to severe in 48%. In the second, IUAs were detected in 16.2% of women evaluated by HSG after second trimester TOP by intra-amniotic prostaglandin induction followed by D&C; a pathologically wide internal cervical os was observed in 12%. CONCLUSIONS: This systematic review suggests a link between TOP and adhesion formation, but, according to the scientific literature and despite new diagnostic facilities, the relationship between the methods of TOP and IUA formation remains unclear. Nevertheless, the reported frequency is in accordance with that found in women following D&C for miscarriage. Further research is required.

PURPOSE: Risk factors for post-surgical adhesions following gynaecological surgery have been identified, but their relative importance has not been precisely determined. No practical tool exists to help gynaecological surgeons evaluate the risk of adhesions in their patients. The purpose of the study was to develop an Adhesion Risk Score to provide a simple tool that will enable gynaecological surgeons to routinely quantify the risk of post-surgical adhesions in individual patients. METHODS: A group of European gynaecological surgeons searched the literature to identify the risk factors and the surgical operations reported as carrying a risk of post-surgical adhesions. Through consensus process of meetings and communication, a four-point scale was then used by each surgeon to attribute a specific weight to each item and collective agreement reached on identified risk factors and their relative importance to allow construct of a useable risk score. RESULTS: Ten preoperative and 10 intraoperative risk factors were identified and weighed, leading to the creation of two sub-scores to identify women at risk prior to and during surgery. The Preoperative Risk Score can range from 0 to 36, and the Intraoperative Risk Score from 3 to 31. Several thresholds between these limits may be used to identify women with low, medium, and high risk of post-surgical adhesions. CONCLUSIONS: Gynaecological surgeons are encouraged to use this Adhesion Risk Score to identify the risk of adhesions in their patients. This will allow better informed use of available resources to target preventive measures in women at high risk of post-surgical adhesions.

BACKGROUND: To evaluate the interobserver agreement and discriminating value of three-dimensional power Doppler ultrasound (3D PDUS) in patients with fibroids. METHODS: An observational prospective cohort study in 19 patients with fibroids. 3D PDUS was performed by one examiner and evaluated by three independent examiners in order to evaluate various vascular parameters: vascular index (VI), flow index, and vascular flow index of the fibroid, the vascular capsule and of its highest vascular area, using both manual and automatic contour modes. The intraclass correlation coefficient and discriminating values were calculated. The correlation between VI and volume was studied using Kendall's Tau test. RESULTS: In the manual contour mode, the VIs of the fibroid and of the vascular capsule had the highest interobserver agreements (intraclass correlation coefficients of 0.89 and 0.87, respectively). Both parameters seem to have good discriminating values, given the large range of these parameters between different fibroids, independent of their volume. The vascularity of the fibroid and capsule was related. VI was not related to the volume of the fibroid. CONCLUSIONS: VI assessed using 3D PDUS is a reproducible parameter in the assessment of fibroid vascularization with discriminating abilities. Additional studies are needed to further evaluate its validity and clinical relevance.

Pelvic organ prolapse (POP) remains a great therapeutic challenge with no optimal treatment available. Tissue maintenance and remodelling are performed by fibroblasts, therefore altered cellular functionality may influence tissue quality. In this study, we evaluated functional characteristics of fibroblastic cells from tissues involved in POP. To rule out normal ageing tissue degeneration, biopsies from 18 premenopausal women were collected from the precervical region (non-POP site) after hysterectomy of 8 healthy and 10 POP cystocele cases (POP-Q stage ≥ II). Extra tissues from the prolapsed sites were taken in the POP cases to distinguish between intrinsic and acquired cellular defects. Twenty-eight primary fibroblastic cultures were studied in vitro. A contractility assay was used to test fibroblast-mediated collagen contraction. Cellular mechanoresponses on collagen-coated or uncoated substrates were evaluated by measuring matrix remodelling factors at protein or gene expression levels. No differences were found between fibroblasts from the controls and the non-POP site of the case group. Fibroblastic cells from the prolapsed site showed delayed fibroblast-mediated collagen contraction and lower production of matrix metalloproteinase-2 (MMP-2) on collagen-coated plates. On uncoated surfaces the gene MMP-2 and its tissue inhibitor of metalloproteinases-2 were up-regulated in POP site fibroblastic cells. In conclusion, fibroblastic cells derived from prolapsed tissues of patients with cystocele, display altered in vitro functional characteristics depending on the surface substrate and compared with non-prolapsed site. This implies an acquired rather than an intrinsic defect for most patients with cystocele, and should be taken into account when trying to improve treatments for POP.

This was a retrospective review of all pregnancies reported after Essure in situ in the Netherlands. Pregnancies included those that were unintentional (resulting from lack of protocol adherence and/or misread confirmation tests) and those that were intentional (resulting from off-label use of Essure micro-inserts for hydrosalpinx closure before in vitro fertilization/intracytoplasmic sperm injection with embryo transfer or in vitro fertilization with embryo transfer after regret of sterilization). The outcomes of 50 pregnancies in women with 1 or 2 micro-inserts in situ were evaluated. Eight unintended pregnancies and 18 intended pregnancies resulted in birth of a full-term healthy baby. Seven infants were delivered via cesarean-section. Two women delivered prematurely by C-section, (singleton after 34 weeks 1 day, twins after 35 weeks 3 days). All babies are healthy and without any congenital anomalies. There were 2 stillbirths after 20 weeks; however, it is unlikely that this was related to the presence of the micro-inserts. In conclusion, it is unlikely that the presence of intratubal micro-inserts interferes with implantation and the developing amniotic sac and fetus.

INTRODUCTION: Pain experience, physical reaction, image quality and adverse events during Gel Instillation Sonohysterography (GIS) can differ using gels with different compositions. As a result, patient satisfaction can also be affected. The effect of two instillation gels, Endosgel versus ExEmgel, using both the Visual Analogue Scale (VAS) and a Continuous Pain Score Meter (CPSM) was therefore compared. METHODS: This single centre double blind randomised controlled trial included 80 women planned for outpatient GIS, diagnosed with abnormal intrauterine bleeding or fertility disorders and suspicion on an intrauterine abnormality. Patients were randomly allocated to the instillation of Endosgel containing chlorhexidine or ExEmgel without chlorhexidine. Primary outcome was reported pain during the procedure using VAS. Secondary outcomes included pain score measured using CPSM, satisfaction to the procedure and preference at 3 weeks and 3 months after the procedure and image quality. A cost benefit analysis was also performed. RESULTS: The reported median VAS concerning pain during gel instillation was comparable in the Endosgel and ExEmgel group, 2.50 (IQR 0.00-5.00) and 2.00 (IQR 0.00-5.75) respectively (p = 0.69). The median VAS of the entire procedure was also similar: both 2.00 (IQR 0.00-5.00) (p = 0.86). CPSM-scores were not significantly different either. Both groups were similar in image quality (p = 0.83) and patient's satisfaction (p = 0.36). CONCLUSION: Concerning the pain experienced during a GIS procedure and patients' satisfaction, the ExEmgel was not proven to be superior to the Endosgel. Our advice is to use the gel that is available at the lowest costs, as the image quality is the same for both Endosgel and ExEmgel.
RESUMO
Introduction: Over the past decade, digital education has seen widespread adoption, particularly accentuated during the COVID-19 pandemic. The post-COVID era has further emphasized the advantages of digital education in terms of cost, availability, and sustainability. However, concerns regarding the efficacy of digital education, particularly in skills-based learning and the absence of social interaction, have been raised. This paper will look at the added value of international, face-to-face, skills-based courses. Method: This study evaluates the potential added value of face-to-face international skills courses using the European "Gynecology Experts Training for Upcoming Professionals" (GET-UP) course. Focus group discussions were conducted with participants and faculty members to explore beliefs, attitudes, and perceptions regarding face-to-face learning. Qualitative analysis was performed using thematic analysis to identify domains of added value. Results: The GET-UP course, conducted over 4 days with a diverse European faculty and participants, highlighted several added-value domains. Themes including diversity, role models, preparation, live interaction, and community emerged from the analysis, emphasizing the significance of face-to-face interaction in enriching the learning experience beyond attaining learning goals. Discussion: The study underscores the importance of face-to-face interaction in educational settings, offering insights into diverse teaching methods, role modeling opportunities, enhanced preparation, live interactions, and fostering a sense of community. While digital education continues to evolve with interactive features, this study suggests that the inherent pressure and dynamics of face-to-face learning provide unique benefits that may not be easily replicated in digital environments. Future research should investigate and validate these findings further to inform educational practices effectively.
RESUMO
STUDY QUESTION: What classification system is more suitable for the accurate, clear, simple and related to the clinical management categorization of female genital anomalies? SUMMARY ANSWER: The new ESHRE/ESGE classification system of female genital anomalies is presented. WHAT IS KNOWN ALREADY: Congenital malformations of the female genital tract are common miscellaneous deviations from normal anatomy with health and reproductive consequences. Until now, three systems have been proposed for their categorization but all of them are associated with serious limitations. STUDY DESIGN, SIZE AND DURATION: The European Society of Human Reproduction and Embryology (ESHRE) and the European Society for Gynaecological Endoscopy (ESGE) have established a common Working Group, under the name CONUTA (CONgenital UTerine Anomalies), with the goal of developing a new updated classification system. A scientific committee (SC) has been appointed to run the project, looking also for consensus within the scientists working in the field. PARTICIPANTS/MATERIALS, SETTING, METHODS: The new system is designed and developed based on (i) scientific research through critical review of current proposals and preparation of an initial proposal for discussion between the experts, (ii) consensus measurement among the experts through the use of the DELPHI procedure and (iii) consensus development by the SC, taking into account the results of the DELPHI procedure and the comments of the experts. Almost 90 participants took part in the process of development of the ESHRE/ESGE classification system, contributing with their structured answers and comments. MAIN RESULTS AND THE ROLE OF CHANCE: The ESHRE/ESGE classification system is based on anatomy. Anomalies are classified into the following main classes, expressing uterine anatomical deviations deriving from the same embryological origin: U0, normal uterus; U1, dysmorphic uterus; U2, septate uterus; U3, bicorporeal uterus; U4, hemi-uterus; U5, aplastic uterus; U6, for still unclassified cases. Main classes have been divided into sub-classes expressing anatomical varieties with clinical significance. Cervical and vaginal anomalies are classified independently into sub-classes having clinical significance. LIMITATIONS, REASONS FOR CAUTION: The ESHRE/ESGE classification of female genital anomalies seems to fulfill the expectations and the needs of the experts in the field, but its clinical value needs to be proved in everyday practice. WIDER IMPLICATIONS OF THE FINDINGS: The ESHRE/ESGE classification system of female genital anomalies could be used as a starting point for the development of guidelines for their diagnosis and treatment. STUDY FUNDING/COMPETING INTEREST(S): None.

BACKGROUND: Ureter injuries are the most dreaded complication in gynecological surgery. Some risk factors for the occurrence of urinary tract injuries are known, but clear guidelines to prevent ureter injuries during laparoscopic hysterectomy (LH) are lacking. The aim of this study was to analyze all known ureter injuries that occurred during LH for a benign indication in the Netherlands, in order to identify patient- and surgeon-related risk factors. METHODS: Ninety-five LH-performing gynecologists were asked to recall all cases of known ureter injuries during LH in their hospital. After identification of ureter injuries, a structured interview was performed with a questionnaire that focused on the identification of predisposing factors which could account for the cause of the injury. RESULTS: Forty-one injuries were detected in 37 patients (4 bilateral ureter injuries) in a 20-year period. The questionnaire could be completed for 31 cases. Predisposing factors were retrospectively assessed and classified into categories: patient-related (i.e., deep infiltrating endometriosis, intraligamentary fibroids) (n = 18), surgeon-related (insufficient experience and/or technique) (n = 16), or both (insufficient experience and difficult case) (n = 8). According to earlier-mentioned recommendations in a Delphi study among experts, in 48.4 % of these ureter injury cases, more than one of the recommended techniques or predisposing conditions were not applied or available. Only one ureter injury was diagnosed during the LH; the mean time to diagnose the injury was 29 days. CONCLUSIONS: Incomplete learning curve, insufficient applied technique such as coagulation of the uterine artery without the use of a uterine manipulator, and/or from the contralateral side and/or without previously performed ureterolysis in case of distorted anatomy may be considered as the main predisposing factors.

INTRODUCTION AND HYPOTHESIS: Little is known about dynamic cell-matrix interactions in the context of pathophysiology and treatments for pelvic organ prolapse (POP). This study sought to identify differences between fibroblasts from women with varying degrees of prolapse in reaction to mechanical stimuli and matrix substrates in vitro. METHODS: Fibroblasts from the vaginal wall of three patients with POP Quantification (POP-Q) system stages 0, II, and IV were stretched on artificial polymer substrates either coated or not coated with collagen I. Changes in morphology and anabolic/catabolic compounds that affect matrix remodelling were evaluated at protein- and gene-expression levels. Statistical analysis was performed using one-way analysis of variance (ANOVA), followed by Tukey-Kramer's post hoc test. RESULTS: POP fibroblasts show delayed cell alignment and lower responses to extracellular matrix remodelling factors at both enzymatic- and gene-expression levels compared with healthy fibroblasts. CONCLUSION: POP fibroblasts, when compared with healthy cells, show differential mechanoresponses on two artificial polymer substrates. This should be taken into account when designing or improving implants for treating POP.

BACKGROUND: Adequate hemostatic techniques are essential for optimal intra- and postoperative results. A number of different hemostatic techniques and devices have been developed over the past few years, but which device should be preferred during laparoscopic and open abdominal procedures? METHODS: We conducted a systematic search for randomized controlled trials (RCTs) that compared the effectiveness and costs of vessel-sealing devices with those of other electrothermal or ultrasonic devices in abdominal surgical procedures. RESULTS: Seven RCTs that included 554 patients met the inclusion criteria. Various procedures that used a vessel-sealing device (LigaSure™) (n = 264) were compared to ultrasonic devices (n = 139) and mono- (n = 20) or bipolar devices (n = 130). LigaSure was favored in two studies with respect to less blood loss, shorter operating time, and lower costs. However, no differences were observed in the other studies. Considering the relatively low number of complications, all hemostatic devices used may be considered relatively safe. None of the studies reported on quality of life or cost effectiveness. CONCLUSIONS: Vessel-sealing devices may be considered safe and their use may reduce costs due to reduced blood loss and shorter operating time in some abdominal surgical procedures compared to mono- or bipolar electrothermal devices. Wider-ranging RCTs of sufficient quality that assess (cost) effectiveness are required to make firm conclusions.

BACKGROUND: The aim of this study was to compare the effects of LigaSure™ versus conventional bipolar techniques on operating time and blood loss during laparoscopic salpingo-oophorectomy in a randomized controlled trial. METHODS: In three teaching hospitals, 100 women undergoing a laparoscopic salpingo-oophorectomy were randomized for LigaSure or conventional bipolar instruments. Primary outcome was operating time (from initial skin incision to removal of the specimen). Secondary outcome measures were total operating time (from initial skin incision to skin closure), time to dissect the ovarian and infundibulopelvic ligaments, intraoperative blood loss, and subjective judgment of the instrument used. RESULTS: There were no differences in operating time and total operating time using LigaSure versus conventional bipolar instruments: 41.0 vs. 39.2 min (p = 0.78; 95 % CI = -10.9 to 14.5) and 54.6 vs. 58.6 min (p = 0.46; 95 % CI = -14.8 to 6.8), respectively. The mean blood loss using LigaSure versus conventional bipolar instruments was 38 vs. 33 mL (p = 0.73; 95 % CI = -22.7 to 32.2). Various subjective efficacy and instrument handling parameters of the two instruments varied among participating centers. CONCLUSION: There were no significant differences in operating time and blood loss with the use of LigaSure compared to conventional bipolar instruments during laparoscopic salpingo-oophorectomy, even after correction for potential confounders.

BACKGROUND: Return to work after gynaecological surgery takes much longer than expected, irrespective of the level of invasiveness. In order to empower patients in recovery and return to work, a multidisciplinary care program consisting of an e-health intervention and integrated care management including participatory workplace intervention was developed. METHODS/DESIGN: We designed a randomized controlled trial to assess the effect of the multidisciplinary care program on full sustainable return to work in patients after gynaecological surgery, compared to usual clinical care. Two hundred twelve women (18-65 years old) undergoing hysterectomy and/or laparoscopic adnexal surgery on benign indication in one of the 7 participating (university) hospitals in the Netherlands are expected to take part in this study at baseline. The primary outcome measure is sick leave duration until full sustainable return to work and is measured by a monthly calendar of sickness absence during 26 weeks after surgery. Secondary outcome measures are the effect of the care program on general recovery, quality of life, pain intensity and complications, and are assessed using questionnaires at baseline, 2, 6, 12 and 26 weeks after surgery. DISCUSSION: The discrepancy between expected physical recovery and actual return to work after gynaecological surgery contributes to the relevance of this study. There is strong evidence that long periods of sick leave can result in work disability, poorer general health and increased risk of mental health problems. We expect that this multidisciplinary care program will improve peri-operative care, contribute to a faster return to work of patients after gynaecological surgery and, as a consequence, will reduce societal costs considerably.
