STUDY QUESTIONWhat classification system is more suitable for the accurate, clear, simple and related to the clinical management categorization of female genital anomalies?SUMMARY ANSWERThe new ESHRE/ESGE classification system of female genital anomalies is presented.WHAT IS KNOWN ALREADYCongenital 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 DURATIONThe 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, METHODSThe 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 CHANCEThe 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 CAUTIONThe 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 FINDINGSThe 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.

The clinical implications of congenital uterine anomalies (CUA), and the benefits of hysteroscopic resection of a uterine septum, were evaluated. Studies comparing reproductive and obstetric outcome of patients with and without CUA and of patients who had and had not undergone hysteroscopic resection of a uterine septum, were evaluated. Meta-analysis of studies indicated that the pregnancy rate was decreased in women with CUA (RR 0.85, 95% CI 0.73 to 1.00; marginally significant finding, P = 0.05). The spontaneous abortion rate was increased in women with CUA (RR 1.68, 95% CI 1.31 to 2.15). Preterm delivery rates (RR 2.21, 95% CI 1.59 to 3.08), malpresentation at delivery (RR 4.75, 95% CI 3.29 to 6.84), low birth weight (RR 1.93, 95% CI 1.50 to 2.49) and perinatal mortality rates (RR 2.43, 95% CI 1.34 to 4.42) were significantly higher in women with CUA. Hysteroscopic removal of a septum was associated with a reduced probability of spontaneous abortion (RR 0.37, 95% CI 0.25 to 0.55) compared with untreated women. Presence of CUA might be associated with a detrimental effect on the probability of pregnancy achievement, spontaneous abortion and obstetric outcome. Hysteroscopic removal of a septum may reduce the probability of a spontaneous abortion.

The new ESHRE/ESGE classification system of female genital anomalies is presented, aiming to provide a more suitable classification system for the accurate, clear, correlated with clinical management and simple categorization of female genital anomalies.

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.

Our data demonstrate the advantages of mini-hysteroscopy and the importance of patient parity and surgeon experience, suggesting that mini-hysteroscopy should always be used, especially for inexperienced surgeons and when difficult access to the uterine cavity is anticipated. They indicate that mini-hysteroscopy can be offered as a first line office diagnostic procedure.

A new technique called transvaginal hydrolaparoscopy is described for the exploration of the tubo-ovarian structures in infertile patients without obvious pelvic pathology. It aims to be an acceptable alternative to diagnostic laparoscopy, a standard but not innocuous procedure which infrequently reveals pathology in the asymptomatic patient. Transvaginal hydrolaparoscopy copy is performed under local anaesthesia using a small diameter optic with the patient in the dorsal position. Cavity distension is achieved with normal saline. Transvaginal hydrolaparoscopy does not provide the familiar and panoramic view of the pelvis given by laparoscopy, but it does have several advantages. These include accurate and atraumatic inspection of adnexal structures without manipulation, with the opportunity to perform dye hydrotubation and salpingoscopy. The risks of a general anaesthetic are avoided, and there is less risk of trauma to major vessels. The high patient acceptability makes transvaginal hydrolaparoscopy suitable as an early stage procedure in the investigation of infertility and as a repeat or second look procedure. Minor operative procedures such as biopsy and adhesiolysis can also be performed. In patients with obvious pelvic pathology, diagnostic laparoscopy will obviously remain the procedure of choice. Transvaginal hydrolaparoscopy deserves full evaluation of its accuracy, risks and benefits before it can be accepted as a new first line technique in gynaecological practice.
