International Consensus Statement for Recommended Terminology Describing Hysteroscopic Procedures.

OBJECTIVE: To develop a consensus statement of recommended terminology to use for describing different aspects of hysteroscopic procedures that can be uniformly used in clinical practice and research. DESIGN: Open forum discussion followed by online video meetings. SETTING: International community of hysteroscopy experts PATIENTS: Not applicable. INTERVENTIONS: Series of online video meetings to complete a previously established agenda until a final agreement for standardized nomenclature was obtained. MEASUREMENT AND MAIN RESULTS: The adoption and implementation of a common terminology to standardize reporting of hysteroscopic procedures was proposed to cover five domains: pain management, healthcare setting, model of care, type of hysteroscopic procedure and the hysteroscopic approach to the uterine cavity. A final agreement was obtained after 3 online video meetings. CONCLUSION: Hysteroscopy is the gold standard technique for the evaluation and management of uterine disorders. A clear definition and understanding of the terminology used to describe hysteroscopic procedures is lacking. The production of this international consensus statement for terminology to describe hysteroscopic procedures, covering pain management, setting, model of care, type of procedure and hysteroscopic approach, has the potential to enable more effective communication for both clinical and research purposes with the ultimate aim of improving patient care and clinical outcomes.

Long-Term Reproductive Outcomes after Hysteroscopic Treatment of Dysmorphic Uteri in Women with Reproductive Failure: An European Multicenter Study.

OBJECTIVE: To evaluate the long-term reproductive outcomes in patients with dysmorphic uterus treated by hysteroscopic metroplasty with miniaturized instruments. DESIGN: Retrospective multicenter cohort study. SETTING: Tertiary care university hospitals. PATIENTS: The study was conducted on 214 women with a dysmorphic uterus (T-shaped, infantilis, or other type of dysmorphic uterus according to the European Society of Human Reproduction and Embryology and the European Society for Gynaecological Endoscopy classification system) with history of primary unexplained infertility (group 1) or repeated (>2) early miscarriages (group 2). Dysmorphic uteri were diagnosed by office hysteroscopy and 3-dimensional transvaginal ultrasound (3D-TVS). INTERVENTIONS: All patients underwent in office hysteroscopic metroplasty using a continuous-flow hysteroscope with a 5 Fr operating channel introduced into the uterine cavity using the vaginoscopic approach. Longitudinal incisions were performed on the fibromuscular constriction rings in the isthmic area and in some cases on the other uterine walls with a 5 Fr bipolar electrode or scissors. At the end of the procedure, an antiadhesive gel was applied into the uterine cavity to minimize adhesion formation. Postsurgical assessment of the uterine cavity was carried out through office hysteroscopy and 3D-TVS. All patients were followed for at least 24 months. MEASUREMENTS AND MAIN RESULTS: The metroplasty was completed in all cases, resulting in a significant increase of uterine cavity volume (100%) and optimization of uterine morphology in 211 of 214 women (98.6%). After 60 months, the overall clinical pregnancy rate was 72.9% (n = 156/214), and the live birth rate was 80.1% (n = 125/156). Specifically, 74 of 156 women (47.4%) conceived spontaneously (with a median time to pregnancy of 5.5 months), of whom 32.4% had previously failed 1 or more attempts at in vitro fertilization/intracytoplasmic sperm injection. CONCLUSION: Our long-term follow-up data demonstrate that the hysteroscopic correction of dysmorphic uteri may result in a high live birth rate in women suffering from unexplained infertility or repeated miscarriages.

Resectoscopic Metroplasty with Uterine Septum Excision: A Histologic Analysis of the Uterine Septum.

STUDY OBJECTIVE: To evaluate the histology of the uterine septum after its complete hysteroscopic excision. DESIGN: Case series. SETTING: Second Gynecological and Obstetric Unit and Pathological Anatomy Department of the University of Bari, Italy. PATIENTS: Thirty-five patients aged between 25 and 41 years who were diagnosed with uterine septum by 3-dimensional ultrasound per the European Society for Human Reproduction and Embryology/European Society of Gastrointestinal Endoscopy 2013/Salim 2003 criteria. In addition, office hysteroscopy was performed to define the anatomy of the uterine cavity and to exclude the presence of other endometrial pathologic conditions. INTERVENTIONS: Operative hysteroscopic septum resection was performed. The septum was initially incised with an "L-shape" bipolar electrode with a 5-mm bipolar mini-resectoscope (KARL STORZ SE & Co. KG, Tuttlingen, Germany). Then, using the bipolar loop, 2 triangles of the septum were excised in parallel, obtaining uninterrupted entire septum-long strips from the fundus to the apex of the septum. These strips were immediately removed from the uterus and reassembled in vitro to reconstruct a macroscopic, 3-dimensional structure of the septum for complete morphologic and histologic evaluations. MEASUREMENTS AND MAIN RESULTS: Patients presented with an average body mass index of 24.8 kg/m2and were all nulliparous. Histologic evaluation of the uterine septa showed a different conformation of the muscle bundles along the septum. Muscle cells in the apex and edges of the septum were arranged in nodules circumscribed by a thin area of collagen fibers. Medium-sized vessels were distributed in the collagen fibers around the muscle cells. Only few capillary vessels were present in the muscle nodules. This pattern was very similar to the cell arrangement in leiomyomas. In the core of the septa, near the base, the muscle bundles showed a linear course with concurrent collagen fibers and vessels. All the aforementioned characteristics were consistently present in every patient. On high-power histologic fields (200×), the muscle portion accounted for 48.3% ± 1.8% (mean, 6%) area in the apex and borders to 48.5% ± 1.3% (mean, 6%) area in the core. Collagen fibers accounted for 27.1% ± 1.1% (mean, 4%) area in the apex and borders to 26.7% ± 1.3% (mean 5%) area in the core. CONCLUSION: By removing the septum as a whole structure, this study allowed us to redefine the concept of the septum as a complex structure according to the islands of muscle fibers irregularly arranged in vertex, in a context of collagen tissue and similar to the structure of myomas. It appears to deeply involve the anterior and posterior uterine walls, resembling a "reverse letter H."

Training and qualification in gynecological minimal access surgery: A systematic review.

Minimally invasive surgery demands specific endoscopic psychomotor skills that are usually acquired outside the operating theatre. We present the results of a systematic analysis to identify how simulation is used during training and qualification in minimal access surgery to improve gynecologist's surgical skills. We found that despite the availability of simulation tools along with methods for training and testing specific endoscopic psychomotor and technical skills, there is no clear evidence of the superiority of one tool or method over the others in skill acquisition. However, prospective studies show that well-guided training courses combined with different trainers and methods improve significantly surgeon's laparoscopic skills and suturing ability, which are unforgettable over time. However, this proficiency could deteriorate over time when it is solely learned and executed on simulation trainers. Structured curricula including theory, simulation, and live-surgery seem to be the best option for trainees. More research in this field is needed.

Symptoms and classification of uterine adenomyosis, including the place of hysteroscopy in diagnosis.

Where histology used the presence of glands and/or stroma in the myometrium as pathognomonic for adenomyosis, imaging uses the appearance of the myometrium, the presence of striations, related to the presence of endometrial tissue within the myometrium, the presence of intramyometrial cystic structures and the size and asymmetry of the uterus to identify adenomyosis. Preliminary reports show a good correlation between the features detected by imaging and the histological findings. Symptoms associated with adenomyosis are abnormal uterine bleeding, pelvic pain (dysmenorrhea, chronic pelvic pain, dyspareunia), and impaired reproduction. However a high incidence of existing comorbidity like fibroids and endometriosis makes it difficult to attribute a specific pathognomonic symptom to adenomyosis. Heterogeneity in the reported pregnancy rates after assisted reproduction is due to the use of different ovarian stimulation protocols and absence of a correct description of the adenomyotic pathology. Current efforts to classify the disease contributed a lot in elucidated the potential characteristics that a classification system should be relied on. The need for a comprehensive, user friendly, and clear categorization of adenomyosis including the pattern, location, histological variants, and the myometrial zone seems to be an urgent need. With the uterus as a possible unifying link between adenomyosis and endometriosis, exploration of the uterus should not only be restricted to the hysteroscopic exploration of the uterine cavity but in a fusion with ultrasound.

Survey among ESGE members on leiomyosarcoma morcellation incidence.

BACKGROUND: Increased awareness of leiomyosarcoma (LMS) risk during myomectomy or hysterectomy is essential. Objective and correct reasoning should prevail on any decision regarding the extent and type of surgery to employ. The anticipated risk of a sarcoma after myoma or uterus morcellation is low, and the frequency of leiomyosarcoma especially in women below the age of 40 is very rare. The prevalence data has a wide range and is therefore not reliable. The European Society of Gynaecological Endoscopy (ESGE) initiated a survey among its members looking into the frequency of morcellated leiomyosarcoma after endoscopic surgery.The ESGE Central office sent 3422 members a structured electronic questionnaire with multiple answer choices for each question. After 3 months, the answers were classified with a unique number in the EXCEL spread sheet. Statistical analysis was done using the SPSS v.18. RESULTS: Out of 3422 members, 294 (8.6%) gynaecologists replied to the questionnaire; however, only 240 perform myomectomies by laparoscopy and hysteroscopy and hysterectomies by laparoscopy. The reported experience in performing laparoscopic myomectomy, hysteroscopic myomectomy, laparoscopic hysterectomy (LH), and laparoscopic subtotal hysterectomy (LSH) on an average was 10.8 (1-32) years. The vast majority of 67.1% had over 5 years of practice in laparoscopic surgery. The total number of 221 leiomyosarcoma was reported among 429,777 minimally invasive surgeries (laparoscopic and hysteroscopic myomectomies and LH and LSH), performed by all doctors in their lifetime. The overall reported sarcoma risk of all types of endoscopic myoma surgeries has been estimated to be 1.5% of operations which is very rare. Categorizing by type, 57 (0.06%) LMS were operated by laparoscopic myomectomy and 54 (0.07%) by hysteroscopic myomectomy, while 38 (0.13%) leiomyosarcoma operated by laparoscopic subtotal hysterectomy and 72 (0.31%) by laparoscopic hysterectomy. The probability of a sarcoma after morcellation to be falsely diagnosed by histopathology as a benign tumour and later identified as a sarcoma in a later examination has been reported and calculated to be 0.2%. The low risk of a sarcoma is also reflected by the small number of surgeries, where only 32 doctors reported that they operated once, 29 twice, and 18 operated on 3-10 sarcomas by laparoscopy during their lifetime. CONCLUSION: The survey demonstrated that myomectomy by hysteroscopy or laparoscopy has similar risks of sarcoma with an estimated incidence of 0.07%, much lower than that by laparoscopic hysterectomy and subtotal hysterectomy. Hence, for young patients with myoma infertility problem and low risk for LMS, myomectomy by MIS can be the first option of treatment. The fact that only 12.5% (216/1728) of uterine sarcoma cases are operated laparoscopically demonstrates the surgeons' awareness and alertness about LMS and the potential of spreading sarcomatous cells after myoma/uterus power morcellation.

Dominant hand, non-dominant hand, or both? The effect of pre-training in hand-eye coordination upon the learning curve of laparoscopic intra-corporeal knot tying.

BACKGROUND: Training of basic laparoscopic psychomotor skills improves both acquisition and retention of more advanced laparoscopic tasks, such as laparoscopic intra-corporeal knot tying (LICK). This randomized controlled trial (RCT) was performed to evaluate the effect of different pre-training programs in hand-eye coordination (HEC) upon the learning curve of LICK. RESULTS: The study was performed in a private center in Asunción, Paraguay, by 60 residents/specialists in gynaecology with no experience in laparoscopic surgery. Participants were allocated in three groups. In phase 1, a baseline test was performed (T1, three repetitions). In phase 2, participants underwent different training programs for HEC (60 repetitions): G1 with both the dominant hand (DH) and the non-dominant hand (NDH), G2 with the DH only, G3 none. In phase 3, a post HEC/pre LICK training test was performed (T2, three repetitions). In phase 4, participants underwent a standardized training program for LICK (60 repetitions). In phase 5, a final test was performed (T3, three repetitions). The score was based on the time taken for task completion system. The scores were plotted and non-linear regression models were used to fit the learning curves to one- and two-phase exponential decay models for each participant (individual curves) and for each group (group curves). For both HEC and LICK, the group learning curves fitted better to the two-phase exponential decay model. For HEC with the DH, G1 and G2 started from a similar point, but G1 reached a lower plateau at a higher speed. In G1, the DH curve started from a lower point than the NDH curve, but both curves reached a similar plateau at comparable speeds. For LICK, all groups started from a similar point, but immediately after HEC training and before LICK training, G1 scored better than the others. All groups reached a similar plateau but with a different decay, G1 reaching this plateau faster than the others groups. CONCLUSIONS: This study demonstrates that pre-training in HEC with both the DH and the NDH shortens the LICK learning curve.

Face and content validity of the virtual reality simulator 'ScanTrainer®'.

BACKGROUND: Ultrasonography is a first-line imaging in the investigation of women's irregular bleeding and other gynaecological pathologies, e.g. ovarian cysts and early pregnancy problems. However, teaching ultrasound, especially transvaginal scanning, remains a challenge for health professionals. New technology such as simulation may potentially facilitate and expedite the process of learning ultrasound. Simulation may prove to be realistic, very close to real patient scanning experience for the sonographer and objectively able to assist the development of basic skills such as image manipulation, hand-eye coordination and examination technique. OBJECTIVE: The aim of this study was to determine the face and content validity of a virtual reality simulator (ScanTrainer®, MedaPhor plc, Cardiff, Wales, UK) as reflective of real transvaginal ultrasound (TVUS) scanning. METHOD: A questionnaire with 14 simulator-related statements was distributed to a number of participants with differing levels of sonography experience in order to determine the level of agreement between the use of the simulator in training and real practice. RESULTS: There were 36 participants: novices (n = 25) and experts (n = 11) who rated the simulator. Median scores of face validity statements between experts and non-experts using a 10-point visual analogue scale (VAS) ratings ranged between 7.5 and 9.0 (p > 0.05) indicated a high level of agreement. Experts' median scores of content validity statements ranged from 8.4 to 9.0. CONCLUSIONS: The findings confirm that the simulator has the feel and look of real-time scanning with high face validity. Similarly, its tutorial structures and learning steps confirm the content validity.

The management of polyps in female reproductive organs.

Polyps of the lower reproductive tract are found in 7.8-50% of women. It has been hypothesized that cytogenetic modifications on chromosomes 6, 7 and 12 as well as epigenetic factors involving enzyme and metabolic activities may cause polyps to develop. Cervical polyps found in 2-5% of cases are of low clinical significance and can cause, although rarely, post coital bleedings. Cervical polyps grow during pregnancy and mucorrhoea. Trans vaginal ultrasound (TVU) provides an excellent diagnostic technique to diagnose the size and the anatomic location of endometrial polyps (EPs). In asymptomatic young woman with small EPs <10 mm in size, conservative management can be safely followed by monitoring the polyp growth. EPs located at the fundal and tubocornual regions mechanically affect fertility and disturb normal cellular function due to chronic inflammation. In cases where Eps are a cause of subfertility mechanical hysteroscopic resection is advisable. When the sole reason for infertility is an EP, the patient often becomes spontaneously pregnant shortly after removal. EP Detection in either peri- or post-menopausal age, in symptomatic or asymptomatic patients calls for meticulous hysteroscopic examination and polypectomy is mandatory. Endometrial curettage is also recommended to rule out sub clinical endometrial hyperplasia or cancer. Hysteroscopic surgery for large EPs using bipolar resectoscopes, hysteroscopic morcellators or shavers are considered equally efficient and safe under general anaesthesia. Recurrence rate of EPs after resection is unknown. The recent advances in TVU and hysteroscopy, however, should provide an accurate diagnosis and effective treatment of polyp in the female reproductive tract with minimal recurrence or surgery complications. The significantly increased incidence of colorectal polyps in cohorts that also had EPs might indicate that patients with EPs should be also referred for colonoscopy. EPs have the lowest incidence of malignant transformation as compared to colon, urinary bladder, oropharyngeal, nasal and laryngeal carcinomas.

Transvaginal laparoscopy: A minimally invasive approach to obtain brush cytology of the Fallopian tube.

OBJECTIVE: To evaluate in a prospective pilot study the feasibility of cytobrushing of the fimbrial end using a transvaginal endoscopic access. STUDY DESIGN: Prospective feasibility study. The procedure was performed in a consecutive series of 15 infertile women referred for a transvaginal laparoscopy as part of their fertility investigation. Tubal cells were collected using a 5Fr cytobrush. Cytology and immunocytochemistry was done. RESULTS: In all patients enough cell material was obtained for analysis, without traumatizing the fimbrial end. Specimens showed the presence of a sufficient amount of cells enabling standard cytologic examinations and immunocytochemistry (Ki 67, p53). CONCLUSION: Fimbrial cytobrushing using the transvaginal approach is an easy and minimally invasive procedure. The easy accessibility of the fimbrial end and the distal ampullary part at TVL allows an accurate collection of tubal epithelial cells. In view of the recent data reporting the Fallopian tube and more specifically the fimbrial end as a possible origin of ovarian carcinoma, further research is needed to evaluate the potential of this technique as a possible screening method for patients at risk for ovarian cancer.

A randomized control trial to evaluate the importance of pre-training basic laparoscopic psychomotor skills upon the learning curve of laparoscopic intra-corporeal knot tying.

BACKGROUND: Training of basic laparoscopic psychomotor skills improves the acquisition of more advanced laparoscopic tasks, such as laparoscopic intra-corporeal knot tying (LICK). This randomized controlled trial was designed to evaluate whether pre-training of basic skills, as laparoscopic camera navigation (LCN), hand-eye coordination (HEC), and bimanual coordination (BMC), and the combination of the three of them, has any beneficial effect upon the learning curve of LICK. The study was carried out in a private center in Asunción, Paraguay, by 80 medical students without any experience in surgery. Four laparoscopic tasks were performed in the ENCILAP model (LCN, HEC, BMC, and LICK). Participants were allocated to 5 groups (G1-G5). The study was structured in 5 phases. In phase 1, they underwent a base-line test (T1) for all tasks (1 repetition of each task in consecutive order). In phase 2, participants underwent different training programs (30 consecutive repetitions) for basic tasks according to the group they belong to (G1: none; G2: LCN; G3: HEC; G4: BMC; and G5: LCN, HEC, and BMC). In phase 3, they were tested again (T2) in the same manner than at T1. In phase 4, they underwent a standardized training program for LICK (30 consecutive repetitions). In phase 5, they were tested again (T3) in the same manner than at T1 and T2. At each repetition, scoring was based on the time taken for task completion system. RESULTS: The scores were plotted and non-linear regression models were used to fit the learning curves to one- and two-phase exponential decay models for each participant (individual curves) and for each group (group curves). The LICK group learning curves fitted better to the two-phase exponential decay model. From these curves, the starting points (Y0), the point after HEC training/before LICK training (Y1), the Plateau, and the rate constants (K) were calculated. All groups, except for G4, started from a similar point (Y0). At Y1, G5 scored already better than the others (G1 p = .004; G2 p = .04; G3 p < .0001; G4 NS). Although all groups reached a similar Plateau, G5 has a quicker learning than the others, demonstrated by a higher K (G1 p < 0.0001; G2 p < 0.0001; G3 p < 0.0001; and G4 p < 0.0001). CONCLUSIONS: Our data confirms that training improves laparoscopic skills and demonstrates that pre-training of all basic skills (i.e., LCN, HEC, and BMC) shortens the LICK learning curve.

Retention of laparoscopic psychomotor skills after a structured training program depends on the quality of the training and on the complexity of the task.

This follow-up RCT was conducted to evaluate laparoscopic psychomotor skills retention after finishing a structured training program. In a first study, 80 gynecologists were randomly allocated to four groups to follow different training programs for hand-eye coordination (task 1) with the dominant hand (task 1-a) and the non-dominant hand (task 1-b) and laparoscopic intra-corporeal knot tying (task 2) in the Laparoscopic Skills Testing and Training (LASTT) model. First, baseline skills were tested (T1). Then, participants trained task 1 (G1: 1-a and 1-b, G2: 1-a only, G3 and G4: none) and then task 2 (all groups but G4). After training all groups were tested again to evaluate skills acquisition (T2). For this study, 2 years after a resting period, 73 participants were recruited and tested again to evaluate skills retention (T3). All groups had comparable skills at T1 for all tasks. At T2, G1, G2, and G3 improved their skills, but the level of improvement was different (G1 = G2 > G3 > G4 for task 1; G1 = G2 = G3 > G4 for task 2). At T3, all groups retained their task 1 skills at the same level than at T2. For task 2, however, a skill decay was already noticed for G2 and G3, being G1 the only group that retained their skills at the post-training level. Training improves laparoscopic skills, which can be retained over time depending on the comprehensiveness of the training program and on the complexity of the task. For high complexity tasks, full training is advisable for both skills acquisition and retention.

Gynaecological endoscopic surgical education and assessment. A diploma programme in gynaecological endoscopic surgery.

In recent years, training and education in endoscopic surgery has been critically reviewed. Clinicians, both surgeons as gynaecologist who perform endoscopic surgery without proper training of the specific psychomotor skills, are at higher risk to increased patient morbidity and mortality. Although the apprentice-tutor model has long been a successful approach for training of surgeons, recently, clinicians have recognised that endoscopic surgery requires an important training phase outside the operating theatre. The Gynaecological Endoscopic Surgical Education and Assessment programme (GESEA) recognises the necessity of this structured approach and implements two separated stages in its learning strategy. In the first stage, a skill certificate on theoretical knowledge and specific practical psychomotor skills is acquired through a high-stake exam; in the second stage, a clinical programme is completed to achieve surgical competence and receive the corresponding diploma. Three diplomas can be awarded: (a) the Bachelor in Endoscopy, (b) the Minimally Invasive Gynaecological Surgeon (MIGS) and (c) the Master level. The Master level is sub-divided into two separate diplomas: the Master in Laparoscopic Pelvic Surgery and the Master in Hysteroscopy. The complexity of modern surgery has increased the demands and challenges to surgical education and the quality control. This programme is based on the best available scientific evidence, and it counteracts the problem of the traditional surgical apprentice-tutor model. It is seen as a major step toward standardisation of endoscopic surgical training in general.

Prevention of intrauterine post-surgical adhesions in hysteroscopy. A systematic review.

OBJECTIVE: The purpose of the present review is to provide a survey of the various measures of preventing adhesions used in hysteroscopic surgery. STUDY DESIGN: A systematic computerized literature search was conducted to provide a survey of the various measures used in hysteroscopic surgery to prevent adhesions. Finally, 29 studies were included in the analysis, showing a wide variety of methods and agents advocated in international literature. They are explained in various sections, based on the IUA prevention approach adopted (surgical technique, early second-look hysteroscopy, barrier method, pharmacological therapy). RESULTS: The results of our review show that (i) use of surgical techniques which reduce the use of electrosurgery should be preferred whenever possible (Level of evidence: 4); (ii) an early second-look hysteroscopy would appear to be an effective preventive, as well as therapeutic, strategy regarding IUA but studies on the topic are too few for relevant evidence; (iii) barriers methods are the most widely used and, among these, gel barriers have been proven to have a significant clinical effect on IUA prevention, because of higher adhesiveness and prolonged residence time on the injured surface (Level of evidence: 1b); (iv) the role of hormonal and antibiotic therapy in the prevention of post-operative IUA is difficult to evaluate as it has been used in association with other prevention strategies in most studies included in our review. CONCLUSIONS: Robust and high quality randomized trials to assess the effectiveness of different anti-adhesion therapies are still needed before one or more of these strategies may be strongly recommended for improving clinical outcomes in women treated by operative hysteroscopy.

Hysteroscopy in recurrent in-vitro fertilisation failure (TROPHY): a multicentre, randomised controlled trial.

BACKGROUND: The success rate of in-vitro fertilisation (IVF) remains low and many women undergo multiple treatment cycles. A previous meta-analysis suggested hysteroscopy could improve outcomes in women who have had recurrent implantation failure; however, studies were of poor quality and a definitive randomised trial was needed. In the TROPHY trial we aimed to assess whether hysteroscopy improves the livebirth rate following IVF treatment in women with recurrent failure of implantation. METHODS: We did a multicentre, randomised controlled trial in eight hospitals in the UK, Belgium, Italy, and the Czech Republic. We recruited women younger than 38 years who had normal ultrasound of the uterine cavity and history of two to four unsuccessful IVF cycles. We used an independent web-based trial management system to randomly assign (1:1) women to receive outpatient hysteroscopy (hysteroscopy group) or no hysteroscopy (control group) in the month before starting a treatment cycle of IVF (with or without intracytoplasmic sperm injection). A computer-based algorithm minimised for key prognostic variables: age, body-mass index, basal follicle-stimulating hormone concentration, and the number of previous failed IVF cycles. The order of group assignment was masked to the researchers at the time of recruitment and randomisation. Embryologists involved in the embryo transfer were masked to group allocation, but physicians doing the procedure knew of group assignment and had hysteroscopy findings accessible. Participants were not masked to their group assignment. The primary outcome was the livebirth rate (proportion of women who had a live baby beyond 24 weeks of gestation) in the intention-to-treat population. The trial was registered with the ISRCTN Registry, ISRCTN35859078. FINDINGS: Between Jan 1, 2010, and Dec 31, 2013, we randomly assigned 350 women to the hysteroscopy group and 352 women to the control group. 102 (29%) of women in the hysteroscopy group had a livebirth after IVF compared with 102 (29%) women in the control group (risk ratio 1·0, 95% CI 0·79-1·25; p=0·96). No hysteroscopy-related adverse events were reported. INTERPRETATION: Outpatient hysteroscopy before IVF in women with a normal ultrasound of the uterine cavity and a history of unsuccessful IVF treatment cycles does not improve the livebirth rate. Further research into the effectiveness of surgical correction of specific uterine cavity abnormalities before IVF is warranted.

The Thessaloniki ESHRE/ESGE consensus on diagnosis of female genital anomalies.

What is the recommended diagnostic work-up of female genital anomalies according to the European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) system? The ESHRE/ESGE consensus for the diagnosis of female genital anomalies is presented. Accurate diagnosis of congenital anomalies still remains a clinical challenge due to the drawbacks of the previous classification systems and the non-systematic use of diagnostic methods with varying accuracy, with some of them quite inaccurate. Currently, a wide range of non-invasive diagnostic procedures are available, enriching the opportunity to accurately detect the anatomical status of the female genital tract, as well as a new objective and comprehensive classification system with well-described classes and sub-classes. The ESHRE/ESGE Congenital Uterine Anomalies (CONUTA) Working Group established an initiative with the goal of developing a consensus for the diagnosis of female genital anomalies. The CONUTA working group and imaging experts in the field have been appointed to run the project. The consensus is developed based on (1) evaluation of the currently available diagnostic methods and, more specifically, of their characteristics with the use of the experts panel consensus method and of their diagnostic accuracy performing a systematic review of evidence and (2) consensus for (a) the definition of where and how to measure uterine wall thickness and (b) the recommendations for the diagnostic work-up of female genital anomalies, based on the results of the previous evaluation procedure, with the use of the experts panel consensus method. Uterine wall thickness is defined as the distance between interostial line and external uterine profile at the midcoronal plane of the uterus; alternatively, if a coronal plane is not available, the mean anterior and posterior uterine wall thickness at the longitudinal plane could be used. Gynaecological examination and two-dimensional ultrasound (2D US) are recommended for the evaluation of asymptomatic women. Three-dimensional ultrasound (3D US) is recommended for the diagnosis of female genital anomalies in "symptomatic" patients belonging to high-risk groups for the presence of a female genital anomaly and in any asymptomatic woman suspected to have an anomaly from routine avaluation. Magnetic resonance imaging (MRI) and endoscopic evaluation are recommended for the sub-group of patients with suspected complex anomalies or in diagnostic dilemmas. Adolescents with symptoms suggestive for the presence of a female genital anomaly should be thoroughly evaluated with 2D US, 3D US, MRI and endoscopy. The various diagnostic methods should be used in a proper way and evaluated by experts to avoid mis-, over- and underdiagnosis. The role of a combined ultrasound examination and outpatient hysteroscopy should be prospectively evaluated. It is a challenge for further research, based on diagnosis, to objectively evaluate the clinical consequences related to various degrees of uterine deformity.
