Presenting and long-term clinical implications and fecundity in females with obstructing vaginal malformations

An unusual case report of transverse vaginal septum presenting as primary amenorrhea

INTRODUCTION AND IMPORTANCE

Outflow tract disorders are uncommon causes of primary amenorrhea. Transverse vaginal septum (TVS) is a rare cause of outflow tract obstruction.

CASE PRESENTATION

A 15-year-old female presented to us with severe abdominal pain. Abdominal examination revealed a boggy mass in the suprapubic region. The diagnosis was made following a history of primary amenorrhea, lower abdominal pain, and pelvic examination which revealed a vaginal septum. She had surgical resection of the vaginal septum and a mold was left in situ to keep the vagina patent during the healing process. The procedure was uneventful and she was able to achieve menstrual flow following surgery, septoplasty being performed after three months.

DISCUSSION

Transverse vaginal septum is an unusual cause of primary amenorrhea. These lesions, albeit rare, usually have a typical presentation and are amenable to surgical management.

CONCLUSION

Although transverse vaginal septum is a rare diagnosis in our practice, it is important to establish early diagnosis and carry out proper management so as to preserve normal physiology and fertility as well as to prevent complications.

Herlyn-Werner-Wunderlich syndrome also known as obstructed hemivagina and ipsilateral renal anomaly: A case report and a comprehensive review of literature

Herlyn-Werner-Wunderlich syndrome, also known as obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), is a Müllerian duct anomaly. It is a rare clinical condition consisting of a duplicated uterus with an oblique vaginal septum that causes partial genital tract outflow obstruction. A urinary tract anomaly, most commonly renal agenesis, is usually present on the obstructed side. The diagnosis of genital tract outflow obstruction is often delayed due to the normal functioning of the unaffected side. The most frequent complications are dysmenorrhea, chronic pelvic pain, infection, infertility and endometriosis. This report describes a 17-year-old G0P0 patient with a history of severe dysmenorrhea and left-sided renal agenesis, who was admitted for complaints of foul vaginal discharge over the past 3 months that was unsuccessfully treated with antibiotics. Transrectal ultrasound revealed the presence of 2 separate hemicavities on transverse and longitudinal views. A cystic lesion with ground-glass opacities was detected between the bladder and a normal-appearing cervix, which was determined to be hematocolpos. The diagnosis of OHVIRA was made. This case highlights the importance of excluding a Müllerian anomaly in the presence of renal system abnormalities. Being aware of the type of anomalies, combinations and variants is crucial to determine the diagnosis and the best surgical approach. Ultrasound was an invaluable imaging exam to determine the type of anomaly and its complexity. Awareness of this syndrome and its variants will prevent misdiagnosis and will help to define the appropriate treatment for these patients.

PAX8 in the Junction between Development and Tumorigenesis

Normal processes of embryonic development and abnormal transformation to cancer have many parallels, and in fact many aberrant cancer cell capabilities are embryonic traits restored in a distorted, unorganized way. Some of these capabilities are cell autonomous, such as proliferation and resisting apoptosis, while others involve a complex interplay with other cells that drives significant changes in neighboring cells. The correlation between embryonic development and cancer is driven by shared proteins. Some embryonic proteins disappear after embryogenesis in adult differentiated cells and are restored in cancer, while others are retained in adult cells, acquiring new functions upon transformation to cancer. Many embryonic factors embraced by cancer cells are transcription factors; some are master regulators that play a major role in determining cell fate. The paired box (PAX) domain family of developmental transcription factors includes nine members involved in differentiation of various organs. All paired box domain proteins are involved in different cancer types carrying pro-tumorigenic or anti-tumorigenic roles. This review focuses on PAX8, a master regulator of transcription in embryonic development of the thyroid, kidney, and male and female genital tracts. We detail the role of PAX8 in each of these organ systems, describe its role during development and in the adult if known, and highlight its pro-tumorigenic role in cancers that emerge from PAX8 expressing organs.

Transverse Vaginal Septum Resection: Technique, Timing, and the Utility of Dilation. A Scoping Review of the Literature

STUDY OBJECTIVE

Transverse vaginal septae (TVS) are congenital, obstructive anomalies of the vagina typically presenting with abdominal pain and amenorrhea. Currently, the literature about surgical management is sparse. Postoperative complications are common. Vaginal dilation either pre- or postoperatively is sometimes recommended, the outcomes of which are poorly described. The aim of this scoping review was to guide surgical planning, namely, timing and postoperative care, to improve surgical outcomes.

DESIGN, SETTING, PARTICIPANTS, AND MAIN OUTCOME MEASURES

This scoping review followed the Joanna Briggs Institute framework. The population of interest was patients 21 years of age or younger with a TVS. MEDLINE, OVID and CINAHL databases were searched using the subject headings listed herein. Literature written in English and French were included. Excluded were reports on patients with concurrent urogenital anomalies or severe developmental disabilities. The resultant articles were reviewed by 2 independent researchers. A third researcher was used in cases of disagreement. Using a descriptive analytical method, data were extracted from the included articles.

RESULTS

We screened 1441 articles for eligibility; 41 articles met criteria, which described 152 cases of TVS. The most common management was simple vaginal excision. Five studies included outcomes from preoperative dilation, and 11 from postoperative dilation. There were 21 cases of postoperative vaginal stenosis; half (11/21) occurred without postoperative dilation.

CONCLUSION

The goal of this review was to describe how TVS are managed and provide guidance for management options. Although the literature was sparse, the authors believe that management in a tertiary center, and surgical delay until the patient is ready to participate in vaginal dilation will improve outcomes for patients with TVS. Further prospective studies are needed to guide surgical planning.

Transverse Vaginal Septum with a Hemiuterus: A Laparoscopic-Guided Abdominoperineal Approach

BACKGROUND

Transverse vaginal septum is a rare Müllerian anomaly that can coexist with other defects.

CASE

A 12-year-old patient was referred to our clinic for cyclic, lower abdominal pain. Magnetic resonance imaging revealed the presence of a transverse vaginal septum, a hemiuterus with a nonfunctioning rudimentary horn, and left unilateral ureter and kidney. The septum was excised laparoscopically assisted by a vaginal dilator to guide the dissection. The mucosal gap of the vagina was then bridged with sutures using the perineal approach. The postoperative course was uneventful and the patient was discharged with instructions for vaginal dilations.

SUMMARY AND CONCLUSION

Early identification of a transverse vaginal septum and careful planning of the operation can improve the outcome of corrective surgery and prevent possible complications.

The impact of hymenectomy on future gynecological and obstetrical outcomes

Background: Imperforated hymen is a rare condition usually diagnosed at puberty due to amenorrhea accompanied by cyclic pelvic pain and sometimes other significant complications such as hematometra, endometriosis, and infertility. The accepted surgical treatment for imperforate hymen and some other hymenal malformation is hymenectomy. However, given low incidence rates, long-term obstetrical and gynecological outcomes in post-hymenectomy women remain poorly understood.Objective: To investigate long-term obstetrical and gynecological outcomes in nulliparous women who underwent a hymenectomy.Study design: Retrospective study comparing gynecological and perinatal outcomes of nulliparous women with and without hymenectomy, who delivered between the years 1988 and 2015 at the Soroka University Medical Center. Univariate analysis was performed as accepted with multivariate logistic regression model used to assess long-term effects of hymenectomy.Results: During the study period, 56 of 74,598 nulliparous women who delivered at the Soroka University Medical Center had previously undergone a hymenectomy. In a univariate analysis, cesarean deliveries were significantly more prevalent among women who had undergone a hymenectomy (30.4 versus 17.6% p = .01) as were infertility treatments (10.7 versus 4.4% p = .04) and dyspareunia (42.9 versus 0.2% p <.001). In a multivariate logistic regression model hymenectomy was found to be an independent risk factor for significant obstetrical and gynecological outcomes defined as one or more of the following: caesarean deliveries, cervical laceration, vaginal laceration, perineal laceration, preterm delivery, cervical incompetence, endometriosis, infertility, and dyspareunia (OR 2.5, 95% CI 1.26-4.93; p = .001).Conclusions: Hymenectomy is associated with significant long-term obstetrical and gynecological complications. Informing medical teams of these risks might promote early detection and minimize associated complications such as laceration-associated blood loss and preterm delivery.

Management of Acute Obstructive Uterovaginal Anomalies: ACOG Committee Opinion, Number 779

Obstructive uterovaginal anomalies may present after puberty with amenorrhea, dysmenorrhea, pelvic pain, recurrent vaginal discharge, or infertility. The evaluation of a patient with a suspected obstructive reproductive anomaly should include a detailed medical history, physical examination, and imaging. The genital examination is critical to differentiate a patient with an imperforate hymen from a patient with labial adhesions, urogenital sinus, transverse vaginal septum, or distal vaginal atresia. Pelvic ultrasonography is the initial imaging method recommended for a patient with cyclic pain and amenorrhea or a patient with persistent dysmenorrhea. It is important to note that diagnosis of a uterine or vaginal anomaly by imaging before puberty can be challenging and misleading because of the small size of the prepubertal uterus and the lack of endometrial stimulation and menstrual distention of the vagina. Consultation with a radiologist experienced with imaging of uterovaginal anomalies may be helpful to determine the most accurate diagnosis. In general, obstructive vaginal and uterine anomalies are not surgical emergencies, and the complexities of these conditions are best managed by gynecologic care providers familiar with the surgical management of these conditions. Given the high risk of stenosis and complications associated with transverse vaginal septum, distal vaginal atresia, and cervical atresia, referral to a center with expertise in the management of these anomalies is paramount. The best long-term outcome is achieved with a complete evaluation, clear understanding of the anomaly, mobilization of appropriate surgical resources, sufficient preoperative counseling, and planned surgical intervention.

Diagnosis and Management of Hymenal Variants: ACOG Committee Opinion, Number 780

At puberty, a patient with an imperforate hymen typically presents with a vaginal bulge of thin hymenal tissue with a dark or bluish hue caused by the hematocolpos behind it. Other findings that may be present include an abdominal mass, urinary retention, dysuria, constipation, and dyschezia. On evaluation, the goal is to differentiate an imperforate hymen from other obstructing anatomic etiologies, such as labial adhesions, urogenital sinus, transverse vaginal septum, or distal vaginal atresia. Surgical intervention is necessary only in symptomatic prepubertal patients. After confirmation of the diagnosis, surgical intervention usually is deferred until pubertal estrogenization has occurred because the imperforate hymen may open spontaneously at puberty. It is important to complete an abdominal and a perineal examination. If the physical examination reveals a bulging hymen and ultrasonography reveals hematocolpos, further imaging is not required. However, if the diagnosis is not certain or there is a concern for a distal vaginal atresia, cervical atresia, an obstructed uterine horn, or transverse or longitudinal vaginal septum, magnetic resonance imaging is recommended. The ideal time for surgical intervention on hymenal tissue is before the onset of pain and after onset of pubertal development, when the vaginal tissue is estrogenized. Surgical management of clinically significant hymenal variations involves excision of the hymenal tissue and rarely is associated with long-term sequelae. If there is concern that the patient has a distal vaginal atresia or a transverse vaginal septum, the patient should be referred to a center with expertise in the management of these conditions.

Fertility and pregnancy outcomes in patients with bicorporeal uterus and blind hemivagina: 20 years of experience in a tertiary referral gynaecological department

BACKGROUND

To evaluate fertility and pregnancy outcomes in patients with uterus bicorporeal and blind hemivagina. Our second objective was to investigate factors predicting fertility and pregnancy outcomes in those patients.

MATERIAL AND METHODS

We conducted a retrospective analysis in a tertiary referring gynaecological department, in France. We included all patients with uterus bicorporeal and blind hemivagina who underwent at least one surgery in our centre. Initial characteristics of the patients included were extracted from their medical charts and patients were contacted to assess their fertility and pregnancies outcomes upon their consent to participate to the study.

RESULTS

Between 1989 and 2010, 79 patients fulfilled inclusion criteria and were selected for analysis. Mean follow up of those patients was of 16.15 (QI 10-21) years. Forty-six patients (58.2%) returned the survey and among them, 21 (45.7%) were fertile, 8 (17.4%) were infertile and 17 (37%) never attempted to get pregnant following initial management. Forty-nine pregnancies were included to assess pregnancies outcomes: 11 (22.5%) early miscarriages, 1 (2.0%) extra-uterine pregnancy, 2 (4.1%) second semester miscarriages and 35 (71.4%) leaded to living birth. Nineteen (54.3%) deliveries occurred by caesarean section and 14 (40.0%) by vaginal delivery. Fifteen pregnancies (42.9%) were complicated. In univariate analysis, adhesiolysis performed at the time of initial surgery was the only factor associated with infertility (p=0.004).

CONCLUSIONS

Fertility seems to be perfectly conserved in those patients and they do not have increased rate of adverse pregnancies outcomes.

Asymptomatic microperforated transverse vaginal septum presenting with primary infertility: a rare form of mullerian anomaly

Transverse vaginal septum is a rare type of mullerian anomaly resulting from failure of the canalization of the vaginal plate at the point where the urogenital sinus meets the mullerian duct and usually presents at menarche with symptoms of outflow tract obstruction. Instead, patients with a perforated septum often have normal menses and usually present with difficulties with intercourse or infertility. A 24-year-old patient with 5 years of infertility is reported. Following assessment, isolated microperforated transverse vaginal septum (U0C0V3 according to the new classification system of the European Society of Human Reproduction and Embryology/European Society for Gynaecological Endoscopy for congenital uterine anomalies) was detected with no additional urogenital anomaly and simple excision of the septum and end-to-end vaginal anastomosis was performed. The patient became pregnant spontaneously 2 months after the operation when sexual intercourse was permitted. Transverse vaginal septum, which presented itself with no clinical findings and only primary infertility, is discussed with a review of the existing literature.

Intralesional Steroid Injections for Recurrent Vaginal Strictures

BACKGROUND

Postoperative complications after transverse vaginal septum excision include stricture formation. The purpose of this report is to describe use of intralesional corticosteroid injections for vaginal strictures.

CASE

A 32-year-old gravida 0 with history of transverse vaginal septum and recurrent strictures presented for follow-up of chronic pelvic pain. After her fourth septum revision, the patient underwent a total of 7 triamcinolone injections at the septum tissue. The course of triamcinolone injections improved the stricture and patient's pain.

SUMMARY AND CONCLUSION

Steroid injection into the vaginal septum tissue can be a safe and effective adjuvant therapy after septum resection. Although it is an established adjuvant therapy in other specialties, further studies are warranted to show a decrease in the recurrence rate of vaginal strictures.

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

STUDY QUESTION

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?

SUMMARY ANSWER

The ESHRE/ESGE consensus for the diagnosis of female genital anomalies is presented.

WHAT IS KNOWN ALREADY

Accurate diagnosis of congenital anomalies still remains a clinical challenge because of the drawbacks of the previous classification systems and the non-systematic use of diagnostic methods with varying accuracy, 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.

STUDY DESIGN, SIZE, DURATION

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.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The consensus is developed based on: (i) 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 by performing a systematic review of evidence and (ii) consensus for the definition of where and how to measure uterine wall thickness and 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.

MAIN RESULTS AND THE ROLE OF CHANCE

Uterine wall thickness is defined as the distance between the 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. Gynecological examination and two-dimensional ultrasound (2D US) are recommended for the evaluation of asymptomatic women. Three-dimensional (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 evaluation. Magnetic resonance imaging (MRI) and endoscopic evaluation are recommended for the subgroup 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 endoscopically.

LIMITATIONS, REASONS FOR CAUTION

The various diagnostic methods should always be used in the proper way and evaluated by experts to avoid mis-, over- and underdiagnosis.

WIDER IMPLICATIONS OF THE FINDINGS

The role of a combined US 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.

An Atypical Presentation of Vaginal Agenesis

BACKGROUND

Vaginal agenesis is rare and generally presents with primary amenorrhea and cyclic abdominal pain. We describe a case in which the diagnosis was delayed due to lack of initial pelvic examination and atypical findings on imaging.

CASE

A 13-year-old girl with a known renal anomaly presented to the emergency department with primary amenorrhea and cyclic abdominal pain. She declined a pelvic examination and had normal laboratory testing and pelvic magnetic resonance imaging results. At 16 months later, she presented again and was diagnosed with vaginal agenesis and a large endometrioma.

SUMMARY AND CONCLUSION

This case illustrates the importance of the physical examination in the evaluation of primary amenorrhea. Further, it demonstrates that hematometra may not be present on imaging. Here, an endometrioma was the only abnormality noted on magnetic resonance imaging after 18 months of retrograde menstruation.

Management of Recurrent Stricture Formation after Transverse Vaginal Septum Excision

Background. A transverse vaginal septum (TVS) is a rare obstructing anomaly, caused due to improper fusion of Müllerian ducts and urogenital sinus during embryogenesis. Case. A 15-year-old girl presented with primary amenorrhea. She had multiple congenital anomalies. Initial examination and imaging investigation revealed the presence of a unicornuate uterus and a TVS. The TVS was excised; however the patient was unable to perform vaginal dilation postoperatively leading to recurrent stricture formation. She underwent multiple surgeries for excision of the stricture. The patient was eventually evaluated every day in the clinic until she was able to demonstrate successful vaginal dilatation in the presence of a clinician. Summary and Conclusion. Properly guided regular and intensive vaginal dilation after TVS excision may decrease the need of reoperations due to recurrent stricture formation.

A rare case of primary amenorrhea with two etiologies, hypothalamic amenorrhea, transverse vaginal septum, and no hematocolpos

We reported a rare case of hypothalamic amenorrhea and transverse vaginal septum. A 28-year-old woman presented with primary amenorrhea and no complaint of abdominal pain. Laparoscopy revealed a small rudimentary uterus with streak ovaries and a vaginal pouch. The patient with diagnosis of Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome was subjected to a vaginoplasty in another fertility center. In our institute, after two courses of estrogen and progesterone, sonography revealed hematocolpos, while, under anesthesia, transverse vaginal septum was resected. Hysteroscopy revealed normal uterine cavity. She became pregnant 5 months postoperatively with controlled ovarian stimulation (COS) in conjunction with intrauterine insemination, and she has two healthy babies now. This case highlights the importance of careful evaluation of all primary amenorrheas. Clinicians should be aware of presence of more than one etiology which causes atypical presentations and accomplishes a systematic strategy for the evaluation of amenorrhea potential to avoid long-term side effects of a misdiagnosis.

The comprehensiveness of the ESHRE/ESGE classification of female genital tract congenital anomalies: a systematic review of cases not classified by the AFS system

STUDY QUESTION

How comprehensive is the recently published European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) classification system of female genital anomalies?

SUMMARY ANSWER

The ESHRE/ESGE classification provides a comprehensive description and categorization of almost all of the currently known anomalies that could not be classified properly with the American Fertility Society (AFS) system.

WHAT IS KNOWN ALREADY

Until now, the more accepted classification system, namely that of the AFS, is associated with serious limitations in effective categorization of female genital anomalies. Many cases published in the literature could not be properly classified using the AFS system, yet a clear and accurate classification is a prerequisite for treatment.

STUDY DESIGN, SIZE AND DURATION

The CONUTA (CONgenital UTerine Anomalies) ESHRE/ESGE group conducted a systematic review of the literature to examine if those types of anomalies that could not be properly classified with the AFS system could be effectively classified with the use of the new ESHRE/ESGE system. An electronic literature search through Medline, Embase and Cochrane library was carried out from January 1988 to January 2014. Three participants independently screened, selected articles of potential interest and finally extracted data from all the included studies. Any disagreement was discussed and resolved after consultation with a fourth reviewer and the results were assessed independently and approved by all members of the CONUTA group.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Among the 143 articles assessed in detail, 120 were finally selected reporting 140 cases that could not properly fit into a specific class of the AFS system. Those 140 cases were clustered in 39 different types of anomalies.

MAIN RESULTS AND THE ROLE OF CHANCE

The congenital anomaly involved a single organ in 12 (30.8%) out of the 39 types of anomalies, while multiple organs and/or segments of Müllerian ducts (complex anomaly) were involved in 27 (69.2%) types. Uterus was the organ most frequently involved (30/39: 76.9%), followed by cervix (26/39: 66.7%) and vagina (23/39: 59%). In all 39 types, the ESHRE/ESGE classification system provided a comprehensive description of each single or complex anomaly. A precise categorization was reached in 38 out of 39 types studied. Only one case of a bizarre uterine anomaly, with no clear embryological defect, could not be categorized and thus was placed in Class 6 (un-classified) of the ESHRE/ESGE system.

LIMITATIONS, REASONS FOR CAUTION

The review of the literature was thorough but we cannot rule out the possibility that other defects exist which will also require testing in the new ESHRE/ESGE system. These anomalies, however, must be rare.

WIDER IMPLICATIONS OF THE FINDINGS

The comprehensiveness of the ESHRE/ESGE classification adds objective scientific validity to its use. This may, therefore, promote its further dissemination and acceptance, which will have a positive outcome in clinical care and research.

Case of early postoperative adhesion in a patient with molimina due to transverse vaginal septum concomitant with imperforate hymen

Transverse vaginal septum is a residual vaginal plate composed of the Müllerian duct and urogenital sinus. Imperforate hymen results from failure of perforation of the membrane between the urogenital sinus and vaginal cavity. We report a rare case of concurrence of these two conditions. A 16-year-old girl had been treated with puncture several times for hematometra and hematocolpos from 13 years of age because of monthly occurrence of lower abdominal pain without menstrual bleeding and was referred to our hospital. Magnetic resonance imaging demonstrated hematometra, hematocolpos and expansion of the vaginal fornix. The imperforate hymen was incised and a slight adhesion at the lower vaginal cavity was detached. After that, a complete transverse vaginal septum, which was 5 mm thick, was identified. It was excised after ultrasonography-guided puncture. Although two cycles of menstrual bleeding took place, molimina recurred. Re-operation was performed 6 months after the first operation, and recurrence of adhesion in the lower vaginal cavity was identified. A silicon dilator was inserted, but she could not use it at home and instead used a tampon. Cyclic menstrual bleeding is observed 4 months after the second operation.

The ESHRE/ESGE consensus on the classification of female genital tract congenital anomalies

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.

Management of lower vaginal agenesis in a patient with unicornuate uterus

BACKGROUND

Absence of the lower vagina occurs from abnormal development of the sinovaginal bulbs and vaginal plate.

CASE

We present a case of an adolescent girl, with a history of VACTERL and VATER status post flap vaginoplasty at 8 m of age and correction of vaginal-urethral fistula, with primary amenorrhea and cyclic pelvic pain. MRI showed a right hematocolpos. On exam the obstructed vagina was deviated to the right. Given prior urologic and rectal surgery, and laterality of unicornuate system, intra-operative ultrasonography (US) was performed. A needle was used to enter the inferior aspect of the obstructed vagina. A pull-through vaginoplasty was performed.

SUMMARY AND CONCLUSION

Vaginal pull-through is the standard treatment for lower vaginal agenesis. In a unicornuate system, the use of intra-operative US is helpful to determine the appropriate angle of dissection.

Clinical approach for the classification of congenital uterine malformations

A more objective, accurate and non-invasive estimation of uterine morphology is nowadays feasible based on the use of modern imaging techniques. The validity of the current classification systems in effective categorization of the female genital malformations has been already challenged. A new clinical approach for the classification of uterine anomalies is proposed. Deviation from normal uterine anatomy is the basic characteristic used in analogy to the American Fertility Society classification. The embryological origin of the anomalies is used as a secondary parameter. Uterine anomalies are classified into the following classes: 0, normal uterus; I, dysmorphic uterus; II, septate uterus (absorption defect); III, dysfused uterus (fusion defect); IV, unilateral formed uterus (formation defect); V, aplastic or dysplastic uterus (formation defect); VI, for still unclassified cases. A subdivision of these main classes to further anatomical varieties with clinical significance is also presented. The new proposal has been designed taking into account the experience gained from the use of the currently available classification systems and intending to be as simple as possible, clear enough and accurate as well as open for further development. This proposal could be used as a starting point for a working group of experts in the field.

Magnetic resonance as an aid in the diagnosis of a transverse vaginal septum

Transverse vaginal septum is a rare, often overlooked congenital abnormality that is typically not diagnosed until adolescence. We present the case of a transverse vaginal septum and partial bicornuate uterus in a 16-year-old adolescent girl with developmental delay and cerebral palsy. Magnetic resonance is an excellent diagnostic tool to delineate the specific anatomy before surgery. The effects of delayed diagnosis and the utility of magnetic resonance in diagnosis will be discussed.

OHVIRA syndrome: rare cause of chronic vaginal discharge in an unmarried female

Chronic vaginal discharge in adolescent and young females, not responding to antibiotics, can pose a diagnostic dilemma for many gynecologists and general practitioners. Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis (OHVIRA syndrome) is a rare congenital anomaly. We present a case of a 22-year-old unmarried female with this syndrome presenting with chronic purulent vaginal discharge. The uniqueness about the case is its much delayed presentation.

Congenital vaginal obstruction in neonates and infants: recognition and management

BACKGROUND

Congenital vaginal obstruction commonly presents after puberty and presentation in infancy is uncommon. Due to lack of awareness, diagnosis may be missed in infants, sometimes with disastrous consequences.

METHOD

A retrospective review of 9 neonates and infants treated for congenital vaginal obstruction in 16 years.

RESULTS

The patients were aged 2 days to 4 months (median 28 days) at presentation. The main presenting feature was a lower abdominal mass, producing intestinal and urinary obstruction in 7 patients. In 2 patients, other conditions were suspected and diagnosis made only intraoperatively and in one patient, diagnosis was incidental during treatment for another condition. The cause of vaginal obstruction were low transverse vaginal septum 6, imperforate hymen 2, high transverse vaginal septum one. Associated anomalies were present in 5 patients (persistent cloaca 3, Hirschsprung disease 1, polydactyly 1). Low vaginal septum was treated by incision and drainage of hydrometrocolpos, imperforate hymen by hymenotomy and drainage of hydrometrocolpos and high vaginal septum by excision. There was recurrence of hydrometrocolpos in one patient who had low vaginal septum, requiring repeat surgery. One patient, in whom diagnosis was missed, died from overwhelming infection. Short term follow-up was good.

CONCLUSION

Congenital vaginal obstruction is an uncommon presentation in this setting. Missing the diagnosis can lead to disastrous consequences. A high index of suspicion is required for prompt recognition and treatment.

Primary Dysmenorrhea: Assessment and Management Update

Many women are familiar with the experience of dysmenorrhea, which can contribute to significant physical and emotional distress and life disruption. However, women may not seek professional expertise in their attempt to alleviate this condition. It is important to assess the beliefs and experiences of all women with dysmenorrhea, including adolescents, as early in gynecologic care as possible. This article reviews the management of primary dysmenorrhea. Midwives can provide valuable assistance to women in their explorations of the variety of treatment options available for the relief of dysmenorrhea, including lifestyle changes, complementary and alternative approaches, analgesics, and hormones.

Congenital malformations of the female genital tract: the need for a new classification system

Current proposals for classifying female genital anomalies seem to be associated with limitations in effective categorization, creating the need for a new classification system that is as simple as possible, clear and accurate in its definitions, comprehensive, and correlated with patients' clinical presentation, prognosis, and treatment on an evidence-based foundation. Although creating a new classification system is not an easy task, it is feasible when taking into account the experience gained from applying the existing classification systems, mainly that of the American Fertility Society.

Laparoscopic drainage of hematocolpos: a new treatment option for the acute management of a transverse vaginal septum

OBJECTIVE

To describe a novel technique for the acute management of a transverse vaginal septum with hematocolpos.

DESIGN

Retrospective case series.

SETTING

Secondary- and tertiary-care centers in Australia and New Zealand.

PATIENT(S)

Three patients with a transverse vaginal septum presenting with pain and a hematocolpos.

INTERVENTION(S)

Laparoscopic drainage of the hematocolpos.

MAIN OUTCOME MEASURE(S)

Pain relief until definitive resection of the transverse vaginal septum.

RESULT(S)

All patients were free of pain after the procedure. Two patients had a second laparoscopic procedure to drain the hematocolpos which had reaccumulated while awaiting definitive surgery. All three patients have undergone resection of the septum.

CONCLUSION(S)

Laparoscopic drainage provides a novel approach to the acute management of a transverse vaginal septum, providing pain relief without compromising the success of definitive surgery which can be performed at a later date.

Müllerian anomalies

The development of the Müllerian system and the female reproductive tract is a complex process involving an integrated series of events with significant potential for abnormal development and anomalies. Structural anomalies of the female reproductive tract may be isolated or occur in association with other congenital anomalies, including renal or bladder anomalies and anorectal malformations. Although rare in occurrence, it is important to be familiar with these conditions for appropriate diagnosis, management, and possible referral. The diagnosis, management, and surgical treatments of female reproductive tract anomalies in girls and young women have advanced with improvements in diagnostic imaging techniques, surgical and nonsurgical techniques and innovative instrumentation and developments.

Extended resectoscopic versus sequential cold knife-resectoscopic excision of the unclassified complete uterocervicovaginal septum: a randomized trial

OBJECTIVE

To determine if resectoscopic sectioning of complete uterocervicovaginal septum is as effective as cold knife excision of the vaginal part followed by resectoscopic cutting of the cervicouterine part in symptomatic patients.

DESIGN

Randomized controlled clinical trial.

SETTING

University hospital.

PATIENT(S)

Thirty-two women with a diagnosis of complete uterocervicovaginal septum who had a history of pregnancy wastage or infertility. They were randomized into two groups: Group A underwent resectoscopic excision of the complete septum starting from the vaginal interoitus; group B underwent cold knife excision of the vaginal part followed by resectoscopic excision of the cervical and uterine parts.

INTERVENTION(S)

Hysteroscopic metroplasty alone or preceded by cold knife excision of the vaginal part.

MAIN OUTCOME MEASURE(S)

Operating time, perioperative bleeding, complications, reproductive outcome, and patient and husband satisfaction.

RESULT(S)

Patients in group A showed significantly less operative time and scar-related dyspareunia. There were no significant differences in the reproductive outcome in the two groups.

CONCLUSION(S)

Resection of the vaginal part of symptomatizing complete vaginocervicouterine septum using resectoscopic metroplasty makes the procedure faster with less possibility of scar-related dyspareunia than cold knife excision.

Treatment of patients with a congenital transversal vaginal septum or a partial aplasia of the vagina. The vaginal pull-through versus the push-through technique

STUDY OBJECTIVE

The aim of this study is to describe the different modalities of congenital obstructing vaginal malformations and the evaluation of techniques to solve the problem.

DESIGN

A retrospective study.

SETTING

The University Hospital Nijmegen, the Netherlands.

PARTICIPANTS

The medical records of 18 patients with congenital obstructive malformations of the vagina operated on by one gynecologist were retrospectively reviewed. The conditions were classified in three groups: group I with one uterus and vagina and with a transverse vaginal septum, group II with a partial vaginal agenesis and group III with a double genital system and a septum with occlusion of one vagina.

MAIN OUTCOME MEASURES

Operating technique used, mold treatment after surgery, menstruation outflow, the possibility of having intercourse and the need for additional surgery.

RESULTS

18 patients were evaluated. Of 10 patients in group I, 8 patients were treated with the pull-through technique and 2 patients with the push-through technique. Four of the patients with a pull-through operation did not get mold treatment; of these patients, 3 needed repeat surgery because of the tendency for constriction. Of 4 patients in group II, 1 patient was treated with the pull-through technique and 3 with the push-through technique. The patient with the pull-through technique needed repeat surgery because of constriction. There was no mold treatment after the first procedure. Group III were 4 patients all treated with the pull-through technique. None of them received mold treatment, and none of these patients needed repeat surgery.

CONCLUSIONS

The push-through method is a good surgical technique for the patients in whom problems of constriction after surgery are expected and for patients with difficulties during surgery. Mold treatment is recommended after surgery in patients with a thick transversal vaginal septum or a partial vaginal aplasia.

Primary amenorrhea with an abdominal mass at the umbilicus

BACKGROUND

Transverse vaginal septum is a rare cause of primary amenorrhea. It has a reported incidence of 1:2,100-1:72,000 and a variety of clinical presentations.

CASE

A 16-year-old patient presented with primary amenorrhea and a large abdominal mass that was palpated on clinical exam and confirmed on MRI imaging. A diagnosis of transverse vaginal septum was ultimately made and the patient underwent a successful surgical excision of the septum and vaginal reconstruction.

CONCLUSION

The presentation, etiology, diagnosis, and surgical treatment of a transverse vaginal septum are discussed.

Pseudoacute abdomen in female caused by haematometrocolpos and haematosalpinx because hymen imperforatus: diagnosis and therapy of imperforate hymen

We present a case of atresia hymenalis in a 12.5 year old female who was admitted to gynecological emergency with a history of severe lower abdominal pains over the course of a few months. Provided are clinical pictures of the “Pseudoacute abdomen”. Upon clinical examination, we found blue, shiny, bulging and imperforated hymen. An abdominal mass was palpated in the vicinity of the navel. Transabdominal ultrasound demonstrated mass filled with thick liquid. “Mercedes hymenal incision” was performed in general anaesthesia. About 1.2 litre of dark, thick blood was removed. Postoperative course was uneventful. The two years of follow-up were characterized with regular psychomotoric development for the age with regular menstrual cycles.

Simple vaginal mold for use in the postoperative care of patients with a transverse vaginal septum

Severe vaginal stenosis is a potentially disabling complication of transverse vaginal septum resection due to the constriction of the resulting circular scar. We describe a vaginal mold that can be easily created by an occupational therapist, and used as a long-term stent of the vagina in young girls.
