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. STUDY FUNDING/COMPETING INTERESTS: None.

Junctional zone thickening: an endo-myometrial unit disorder.

Adenomyosis is a disease defined by histopathology, mostly of hysterectomy specimens, and classification is challenged by the disagreement of the histologic definition. With the introduction of Magnetic Resonance Imaging (MRI) and two- and three-dimensional ultrasound, the diagnosis of adenomyosis became a clinical entity. In MRI and US, adenomyosis ranges from thickening of the inner myometrium or junctional zone to nodular, cystic, or diffuse lesions involving the entire uterine wall, up to a well-circumscribed adenomyoma or a polypoid adenomyoma. The absence of an accepted classification and the vague and inconsistent terminology hamper basic and clinical research. The sub-endometrial halo seen at US and MRI is a distinct entity, differing from the outer myometrium by its increased nuclear density and vascular structure. The endometrium and the sub-endometrial muscularis or archimetra are of Müllarian origin, while the outer myometrium is non-Mullerian mesenchymal. The junctional zone (JZ) is important for uterine contractions, conception, implantation, and placentation. Thickening of the JZ can be considered inner myometrium adenomyosis, with or without endometrial invasion. Changes in the JZ should be considered a different entity than myometrial clinically associated with impaired conception, implantation, abnormal uterine bleeding, pelvic pain and obstetrical outcome. Pathology of the basal endometrium and JZ is a separate entity and should be identified as an endo-myometrial unit disorder (EMUD).

From complication to litigation: The importance of non-technical skills in the management of complications.

Complications do occur in daily clinical life and can sometimes lead to litigation, which adversely affect the entire health care system, leading to a loss of confidence in medical providers, an increase in defensive medical practice and high professional indemnity insurance costs. Some complications are inevitable but can be minimised by completing a structured training programme. The likelihood of litigation can be reduced when adequate and clear information is given to the patient preoperatively. Non-technical skills are essential in complication management and crucial if confronted with litigation. Checklists and documentation of medication and surgical steps should be routine in all surgeries. Awareness of the complexity of the planned operation, theatre set-up and equipment are important in preventing complications. Mental preparation of surgeons is of the utmost importance in order to be able to confront any problem. When complications occur, remaining calm, calling for assistance, effective team leadership and harmony in the team are important in managing the situation. Good and effective communication with the patient and relatives, offering explanations, apologies and timely intervention without delays reduce the risk of litigation and strengthen any defence in court.

Benign and malignant pathology of the uterus.

The diagnosis of a uterine myoma size and location can be very precise when a 3D sonograph and knowledge are available. The majority of fibroids are asymptomatic, and expectant management is recommended. In young patients, fibroids cause infertility and in middle-aged women, abnormal uterine bleedings. Laparoscopic myomectomy is the preferred way of surgery for IM and SS fibroids, versus hysteroscopy for SM fibroids. In both cases, the size, number of fibroids and the surgeon's experience determine the limitations of the MIGS. Medical treatments provide only temporary tumor reduction and symptom alleviation. Leiomyosarcoma risk is higher in older women usually carrying fibroids larger than 8 cm. There are no other pathognomonic parameters ruling out a sarcoma. In case of suspected fibroid malignancy, the best treatment option is laparotomy and total hysterectomy. Myomectomy complications can be reduced when MIGS is performed by a surgeon with proper training and experience.

Prevention and Management of Complications in Laparoscopic Myomectomy.

Myomectomy aims to preserve fertility, treat abnormal uterine bleeding, and alleviate pain. It should cause minimal damage to the endometrium, while being tolerable and durable, and reduce the incidence of myoma recurrence and complications including bleeding, hematoma, adhesions, and gravid uterus perforation. Training and experience are crucial to reduce complications. The surgical strategy depends on imaging information on the myomas. The position of the optical and secondary ports will determine the degree of ergonomic surgery performance, time and difficulty of myoma enucleation, and the suturing quality. Appropriate hysterotomy length relative to myoma size can decrease bleeding, coagulation, and suturing times. Bipolar coagulation of large vessels, while avoiding carbonization and myometrium gaps after suturing, may decrease the risk of myometrial hematoma. Quality surgery and the use of antiadhesive barriers may reduce the risk of postoperative adhesions. Slow rotation of the beveled morcellator and good control of the bag could reduce de novo myoma and endometriosis. Low intra-abdominal CO2 pressure may reduce the risk of benign and malignant cell dissemination. The benefits a patient gains from laparoscopic myomectomy are greater than the complication risks of laparoscopic morcellation. Recent publications on laparoscopic myomectomies demonstrate reduced hospitalization stays, postoperative pain, blood loss, and recovery compared to open surgery.

Simulation and Training of Gynaecological Skills.

In order to offer our patients, the "state of the art" treatment in gynaecology, we need a structured teaching program for trainees concerning the gynaecological skills. In recent years, training and education in endoscopic surgery has been critically reviewed. Clinicians, both surgeons as gynaecologists who perform endoscopic surgery without proper training of the specific psychomotor skills, are at higher risk to increased patient morbidity and mortality. The traditional apprentice-tutor model is no longer valid for developing all skills necessary in gynaecological surgery, particularly in endoscopy. Endoscopic training should happen at both the theoretical and the practical skill level. The acquisition of the correct knowledge regarding general laparoscopy, hysteroscopy and standard level procedures is as important as learning the necessary psychomotor skills to successfully perform endoscopic manipulations. Training in the operating room can only start when it is proven that knowledge and skills are present. To learn and train total abdominal hysterectomy by laparotomy there are inexpensive simple models that can be used, which are easy to reproduce. The development, construction, cost, and utility of a low-cost and anatomically representative vaginal hysterectomy simulator also has been described. The complexity of modern surgery has increased the demands and challenges to surgical education and the quality control.

Vaginal lichen sclerosus: report of two cases.

BACKGROUND: Lichen sclerosus most commonly affects the genital area. Contrarily to lichen planus, the involvement of the oral or vaginal mucosa is rare. Only four cases of vaginal lichen sclerosus have been described in the literature. CASE REPORT: The authors report two cases of postmenopausal women with a history of vulvar pruritus and burning. Both presented with lesions of the vaginal mucosa compatible with lichen sclerosus, and genital prolapse. Vaginal biopsies confirmed the diagnosis. Initial treatment with topical clobetasol was effective in one of the patients, but in the other patient line therapy with pimecrolimus, triamcinolone, and retinoids was needed. CONCLUSION: Vaginal lichen sclerosus may be underdiagnosed and genital prolapse may favour the development of vaginal lesions.

Uncommon presentations of an uncommon entity: OHVIRA syndrome with hematosalpinx and pyocolpos.

Müllerian malformations result from defective fusion of the Müllerian ducts during development of the female reproductive system. The least common form of these malformations is Herlyn-Werner-Wunderlich syndrome characterized by obstructed hemivagina and ipsilateral renal anomaly (OHVIRA). The most common presentation of this syndrome is a mass secondary to hematocolpos, pain, and dysmenorrhea. Clinical diagnosis is very challenging and requires imaging studies in which ultrasound and MRI play an essential role in the diagnosis, classification and treatment plan. We report two cases of this syndrome, featuring two very rare clinical presentations: hematosalpinx and pyocolpos. The clinical course of the pathology is not standard and each patient is treated accordingly.

From Clinical Symptoms to MR Imaging: Diagnostic Steps in Adenomyosis.

Adenomyosis or endometriosis genitalis interna is a frequent benign disease of women in fertile age. It causes symptoms like bleeding disorders and dysmenorrhea and seems to have a negative effect on fertility. Adenomyosis can be part of a complex genital and extragenital endometriosis but also can be found as a solitary uterine disease. While peritoneal endometriosis can be easily diagnosed by laparoscopy with subsequent biopsy, the determination of adenomyosis is difficult. In the following literature review, the diagnostic methods clinical history and symptoms, gynecological examination, 2D and 3D transvaginal ultrasound, MRI, hysteroscopy, and laparoscopy will be discussed step by step in order to evaluate their predictive value in the diagnosis of adenomyosis.

Implementation of minimal invasive gynaecological surgery certification will challenge gynaecologists with new legal and ethical issues.

The introduction of a certification / diploma program in Minimal Invasive Surgery (MIS) is expected to improve surgical performance, patient's safety and outcome. The Gynaecological Endoscopic Surgical Education and Assessment programme (GESEA) and the ESHRE Certification for Reproductive Endoscopic Surgery (ECRES) provides a structured learning path, recognising different pillars of competence. In order to achieve a high level of competence a two steps validation is necessary: (a) the individual should be certified of having the appropriate theoretical knowledge and (b) the endoscopic psychomotor skills before entering in the diploma programme reflecting the surgical competence. The influence of such an educational and credentialing path could improve safety and offer financial benefits to the hospitals, physicians and healthcare authorities. Moreover the medicolegal consequences can be important when a significant amount of surgeons possess the different diplomas. As the programs are becoming universally accessible, recognised as the best scientific standard, included in the continuous medical education (CME) and continuous professional development (CPD), it is expected that a significant number of surgeons will soon accomplish the diploma path. The co-existence and practice of both non-certified and certified surgeons with different degrees of experience is unavoidable. However, it is expected that national health systems (NHS), hospitals and insurance companies will demand and hire doctors with high and specific proficiency to endoscopic surgery. When medico-legal cases are under investigation, the experts should be aware of the limitations that individual experience provides. The court first of all examines and then judges if there is negligence and decides accordingly. However, lack of certification may be considered as negligence by a surgeon operating a case that eventual faces litigation problems. Patients' safety and objective preoperative counselling are mandatory, directly connected to MIS certification while eliminating any dispute of surgeons' credibility.

The European Academy laparoscopic "Suturing Training and Testing'' (SUTT) significantly improves surgeons' performance.

UNLABELLED: The efficiency of suturing training and testing (SUTT) model by laparoscopy was evaluated, measuring the suturingskill acquisition of trainee gynecologists at the beginning and at the end of a teaching course. During a workshop organized by the European Academy of Gynecological Surgery (EAGS), 25 participants with three different experience levels in laparoscopy (minor, intermediate and major) performed the 4 exercises of the SUTT model (Ex 1: both hands stitching and continuous suturing, Ex 2: right hand stitching and intracorporeal knotting, Ex 3: left hand stitching and intracorporeal knotting, Ex 4: dominant hand stitching, tissue approximation and intracorporeal knotting). The time needed to perform the exercises is recorded for each trainee and group and statistical analysis used to note the differences. Overall, all trainees achieved significant improvement in suturing time (p < 0.005) as measured before and after completion of the training. Similar significantly improved suturing time differences (p < 0.005) were noted among the groups of trainees with different laparoscopic experience. In conclusion a short well-guided training course, using the SUTT model, improves significantly surgeon's laparoscopic suturing ability, independently of the level of experience in laparoscopic surgery. KEY WORDS: Endoscopy, laparoscopic suturing, psychomotor skills, surgery, teaching, training suturing model.

Computer-aided diagnosis in hysteroscopic imaging.

The paper presents the development of a computer-aided diagnostic (CAD) system for the early detection of endometrial cancer. The proposed CAD system supports reproducibility through texture feature standardization, standardized multifeature selection, and provides physicians with comparative distributions of the extracted texture features. The CAD system was validated using 516 regions of interest (ROIs) extracted from 52 subjects. The ROIs were equally distributed among normal and abnormal cases. To support reproducibility, the RGB images were first gamma corrected and then converted into HSV and YCrCb. From each channel of the gamma-corrected YCrCb, HSV, and RGB color systems, we extracted the following texture features: 1) statistical features (SFs), 2) spatial gray-level dependence matrices (SGLDM), and 3) gray-level difference statistics (GLDS). The texture features were then used as inputs with support vector machines (SVMs) and the probabilistic neural network (PNN) classifiers. After accounting for multiple comparisons, texture features extracted from abnormal ROIs were found to be significantly different than texture features extracted from normal ROIs. Compared to texture features extracted from normal ROIs, abnormal ROIs were characterized by lower image intensity, while variance, entropy, and contrast gave higher values. In terms of ROI classification, the best results were achieved by using SF and GLDS features with an SVM classifier. For this combination, the proposed CAD system achieved an 81% correct classification rate.

Prophylactic antibiotics in abdominal hysterectomy.

BACKGROUND: The cephalosporins, which have been widely used in gynecologic surgery, are considered by many to be the drug of choice for chemoprophylaxis. However, their benefit in total abdominal hysterectomy has remained controversial. This study was done to evaluate the effectiveness of the commonly used cephalosporins in preventing inflammatory complications which may occur after elective abdominal hysterectomy. STUDY DESIGN: A MEDLINE and manual review of the literature from the past 15 years (1977 to 1991), using the terms "prophylactic antibiotics," "abdominal hysterectomy," and "cephalosporins," was performed. Seventeen prospective trials using cephalosporin prophylaxis alone for 24 hours perioperatively were evaluated. A meta-analysis of the 2,752 study and control patients abstracted was performed to compare postoperative infection and febrile morbidity rates. RESULTS: The cephalosporin group as well as the various generations and individual drugs were found to be useful in preventing postoperative infection (p < 0.001). Febrile morbidity, however, was effectively prevented (p < 0.001) by first but not by some second and third generation drugs. Multivariate analysis revealed no advantage for the newer, more expensive second and third generation cephalosporins studied. When adjusted for confounding factors, the number of doses, the amount of the dose, and the route of administration had significant impact on the outcome events. CONCLUSIONS: Chemoprophylaxis with cephalosporins was found to be effective in preventing posthysterectomy infectious complications. A single dose, preoperative injection of first (cefazolin) or second (cefoxitin) generation cephalosporin, when administrated intravenously, has been shown to yield the best, cost-effective clinical results.

High risk pregnancy outcome following induction of labour.

OBJECTIVE: To evaluate whether induction of labour, performed in a high risk obstetric population, when medically indicated, carries an increased risk for operative delivery and maternal and fetal complications. The secondary goal was to study the effect of the various induction methods used on these outcomes and labour time. STUDY DESIGN: This study was carried out at a level [1] university hospital. A group of 210 women who were induced for various indications, were compared to our general parturient population. Main outcome measures were cesarean section (CS) and instrumental delivery rates, intra-partum and post-partum complications, APGARs 1' and 5' and labour time by induction method. RESULTS: No significant increase in the rates of primary CS (8.6 vs. 7.1%) and instrumental delivery (15.7 vs. 12.7%), were found in the induction high risk group as compared to our general obstetric population. Intra-partum complications and fetal outcome were comparable in both groups. A comparison of methods of induction used (oxytocin, PgE2, Amniotomy) revealed a less favorable outcome with the oxytocin induction method which showed an elevated intra-partum complication rate (P < 0.01) and a tendency toward lower Apgar scores and higher CS rate. CONCLUSIONS: Induction of labour performed in a high-risk obstetric population is safe, carrying no significant increase in CS and neonatal complication rates. Of the three methods of induction used, oxytocin induction showed the least favorable outcome for both mother and her offspring.

Hyperreactio luteinalis associated with non-immune hydrops fetalis--the role of pituitary hormones.

The level of pituitary hormones was measured in the serum and cysts' aspirate in a case of hyperreactio luteinalis (HL) complicating non-immune hydrops fetalis. The level of follicular stimulating hormone (FSH), prolactin and growth hormone (GH) was within normal range for pregnancy in both the serum and cysts' aspirate. The importance of increased luteinizing hormone (LH) level which was demonstrated in the cysts' fluid should further be determined.

Expression of the imprinted H19 oncofetal RNA in epithelial ovarian cancer.

STUDY: To examine the expression of the imprinted maternally expressed H19 gene in benign, low malignant potential (borderline) and malignant surface epithelial ovarian tumors. DESIGN: In situ hybridization for H19 RNA using S-labeled and digoxigenin-labeled probes was performed on paraffin sections of ovarian surface epithelial tumors. The serous tumors included nine section cystadenomas, twelve serous tumors of low malignant potential and twenty serous carcinomas, grade I-IIII (FIGO classification). A smaller group included two mucinous cystadenomas, four mucinous tumors of low malignant potential and two mucinous cystadenocarcinomas. RESULTS: H19 expression was found to be positive in 6/9 (67%) serous cystadenomas, 9/12 (75%) of serous tumors of low malignant potential and 13/20 (65%) of invasive serous carcinomas. Expression in mucinous tumors was confined to the stroma beneath the epithelial lining. CONCLUSION: H19 is expressed in the majority of serous epithelial tumors. Taking into consideration the high percentage of H19 expressing serous ovarian neoplasms we suggest that H19 RNA may be used as an adjuvant tumor marker for the diagnosis and mainly for staging and follow-up of patients with serous ovarian carcinoma.

Ovulation induction and risk of endometrial cancer: a pilot study.

OBJECTIVE: To determine whether women with endometrial carcinoma are more likely to have been exposed to fertility drugs, in particular clomiphene, than healthy population controls. STUDY DESIGN: A nationwide case-control, pilot study. About 128 living women 35-64 years old, with a histologically confirmed diagnosis of endometrial carcinoma that was first diagnosed and reported to The Israel Cancer Registry between 1 January 1989 and 31 December 1992 were enrolled. The controls were 255 women from the same dialing areas selected by random digit dialing. A variety of demographic and clinical parameters were compared between cases and controls. A multivariate logistic model, controlling for age, was used to assess the independent effects of factors found to be significantly associated with endometrial cancer on univariate analysis. RESULTS: About 7 women with endometrial carcinoma (5.5%) and 10 healthy controls (3.9%) reported that they had used any fertility drug (crude odds ratio (OR) 1.4; 95% confidence interval (CI) 0.47-4.2). Use of fertility drugs did not meet the criteria for entry into the logistic model. The following parameters were found to be independently associated with endometrial cancer controlling for age, European-American background OR=2.2, (95% CI 1.3-3.7, P=0.004); nulliparity OR=2.7 (95% CI 1.1-6.5, P=0.03); history of infertility OR=1.8 (95% CI 1.0-3.3, P=0.05); BMI> or =27 OR=2.3 (95% CI 1.4-3.9, P=0.001). The use of oral contraceptives and IUD were found to be protective, OR=0.29 and 0.37, respectively, (95% CI 0.14-0.61, P=0.001 and 0.19-0.70, P=0.003, respectively). CONCLUSIONS: We found no evidence that the use of ovulation induction agents, including clomiphene citrate, are associated with a higher risk of endometrial carcinoma. The association between infertility drugs and endometrial carcinoma should be examined in other, larger studies.

Cesarean scar endometriosis.

A mass located in a scar area during examination is an infrequent phenomenon. Such a mass can be associated with keloid, hematoma, granuloma, hernia or neoplasm. Two cases of scar endometriosis are reported. The late onset of symptoms after surgery (average 4.5 years) is the usual reason for misdiagnosis. Awareness of this infrequent and late postoperative complication would increase the detection rate. Surgical excision remains the treatment of choice and should be accomplished without complications.

Effect of epidural analgesia on duration and outcome of induced labor.

OBJECTIVE: To evaluate the effect of epidural block on the duration of labor and maternal and fetal outcome in induced-labor patients. METHOD: 210 women admitted for induction of labor at a level III university hospital, during the year 1991, were studied. Of these, 112 were given an epidural block and 98 served as controls. Outcome measures studied were: induction time and time in labor, c-section and instrumental delivery rates, intra-partum and post-partum complications, and Apgar scores at 1 and 5 min. RESULT: Multiple regression analysis revealed that epidural analgesia, before and after adjustment for confounding factors, significantly prolonged labor time (P < 0.0001) and was associated with an increase in instrumental delivery rates (P < 0.04). A significant reduction in intra-partum complication rate (FHR changes, meconium) was observed (OR = 0.32; P < 0.03), while c-section rate and Apgar scores were not found to be influenced by epidural analgesia. CONCLUSION: Epidural anesthesia, significantly prolongs labor time in induced patients. While instrumental delivery was more prevalent in these parturients, c-section rate was not increased and intra-partum complications were significantly reduced in these patients.
