Ureteral endometriosis: MR imaging appearance for predicting complex procedures

Rationale and objectivesTo describe MRI characteristics of ureteral endometriosis (UE) in identifying intrinsic involvement of the ureteric wall and predicting complex procedures. MethodsThirty-three UE lesions in 30 patients treated for UE over a 20-year period were reviewed. A systematic analysis of 13 MRI (ureteric wall thickening, circumference, T1 signal, T2 signal, ureterectasis, lateral parametrial endometriosis (LPE), rectal endometriosis, the foregoing three-characteristic diameter, ovarian endometriomas, adenomyosis, paraurethral endometriosis) and 5 clinical (age, BMI, CA125, creatinine and rAFS stage) characteristics was performed. MRI results were compared to histology and surgical procedure performed (simple versus complex ureteral procedures). ResultsTwenty-five extrinsic and 8 intrinsic UE were pathologically identified. Twenty lesions underwent a simple procedure, and 12 underwent a complex procedure, with 1 ureteroscopic biopsy. There were significant differences in the characteristics of ureteric wall thickening, the diameter of dilated ureter and LPE, rectal endometriosis and adenomyosis between extrinsic and intrinsic UE (p < 0.05). UE was associated with LPE (p = 0.033). The criteria of ureteral wall thickening more accurately predicted intrinsic UE than circumference, but the AUC was not significant difference (AUC, 0.806 and 0.639; 95 % CI, [0.594, 0.937] and [0.419, 0.823], respectively; p = 0.350). There were significant differences in creatinine, thickening and adenomyosis between the simple and complex procedures (p < 0.05). In 11 lesions with the absence of ureterectasis, 4 lesions with hydronephrosis and thickening were intrinsic and underwent complex procedures, while 7 lesions extrinsic and simple. ConclusionsUreteric wall thickening as a analytical criterion may accurately predict intrinsic UE and complex ureteric procedures.

Endometriosis: Age at diagnosis and the severity of the disease

BackgroundEndometriosis is often described as a progressive disease beginning with menarche and menstrual bleeding. However, this is controversial, as the origin of the disease remains unknown. The objective of this study was to investigate the association between the severity of endometriosis and age at initial diagnosis. Material and MethodsThis prospective multicenter cohort study included 964 patients, newly and histologically diagnosed with endometriosis during laparoscopic treatment. The main outcome measures were diagnostic lesions with staging according to rAFS (revised American Fertility Society) scores, intensity of pain based on VAS (Visual Analog Scale) scores and quality of life from SF-36 questionnaire results. Age was treated as a categorical variable. Univariate and multivariable analyses (linear and multinomial ordinal) were conducted taking into account two by two multiple comparisons. The results were expressed with effect sizes and 95 % confidence intervals. Main findingsNo significant association between age and rAFS stage was found (p = 0.053). The percentage of patients with a deep nodule ≥ 2 cm was respectively 20 %, 25 %, 21 %, 18 % and 9 % for patients aged ≤ 25, 26–30, 31–35, 36–40 and >40 years respectively (p = 0.005). For dysmenorrhea, 64 %, 61 %, 54 %, 51 % and 32 % of patients aged ≤25, 26–30, 31–35, 36–40 and >40 years respectively reported a VAS score of ≥7 (p ≤ 0.001). ConclusionProspective data obtained in patients newly diagnosed with endometriosis, revealed that the rAFS score is not related to patient age, and that the percentage of patients with a nodule ≥ 2 cm and severe dysmenorrhea did not increase with age. These percentages were significantly lower in patients aged > 40.

Prevalence, Surgical, and Medical Management of Patients with Endometriosis amongst Indian Women

Objective: This study aims to determine the prevalence of endometriosis in women in South India, the epidemiological factors involved, and evaluate the symptomatic burden associated with it. Design: A large-scale Hospital-based study was conducted among women of reproductive age (16 to 44 years) in the state of Telangana between March 2018 and March 2023. A randomized multi-stage stratified sampling method was adopted and included 2,400 women who were screened using a validated structured questionnaire. Patients presenting with symptoms indicative of endometriosis underwent additional assessment using abdominal ultrasonography (AUS) and serum cancer antigen 125 (CA125) tests. For confirmation, laparoscopy was offered to the patients who consented. Patients who declined laparoscopy were given the option of undergoing magnetic resonance imaging (MRI) instead. Results: Among 2,400 women who participated, 60 women have been diagnosed with endometriosis during the 5-year study period. The prevalence of endometriosis was found to be 2.5%. The mean age of participants was 15.2 ± 3.5 years and the mean age at menarche was found to be 12.9 ± 1.1 years. Out of 60 participants diagnosed with endometriosis 30% (n = 18) experienced irregular menstrual cycles. Approximately 33.3% (n = 20) of the women reported experiencing Dysmenorrhea, with 28.4% (n = 17) complaining of dyspareunia. Among the cases with menstrual pain, exhibited ultrasound findings suggestive of endometriosis, with elevated CA125 levels observed in 45% (n = 27) of these cases. All 60 patients who consented to laparoscopic confirmation, exhibited positive histo-pathological evidence of endometriosis. The prevalence of endometriosis is found to be significant in women of reproductive age group and found to be associated with high rates of infertility in 15 (25%) patients. The results of this study showed that the prevalence of endometriosis is found to be 2.5% which is similar to the other studies reported. The severity of endometriosis during laparoscopy was assessed using the rAFS staging system, revealing rates of 55% and 45% for disease in Stages I &amp; II, Stages III, &amp; IV, respectively. Conclusion: Our study concludes that endometriosis predominantly affects women in the reproductive age group and is often associated with primary infertility. The laparoscopic findings are identified as a standard tool for both diagnosis and treatment of endometriosis.

ASPN Is a Potential Biomarker and Associated with Immune Infiltration in Endometriosis.

Objective: Endometriosis is a benign gynecological disease characterized by distant metastasis. Previous studies have discovered abnormal numbers and function of immune cells in endometriotic lesions. We aimed to find potential biomarkers of endometriosis and to explore the relationship between ASPN and the immune microenvironment of endometriosis. Methods: We obtained the GSE141549 and GSE7305 datasets containing endometriosis and normal endometrial samples from the Gene Expression Omnibus database (GEO). In the GSE141549 dataset, differentially expressed genes (DEGs) were found. The Least Absolute Shrinkage and Selection Operator (Lasso) regression and generalized linear models (GLMs) were used to screen new biomarkers. The expression levels and diagnostic utility of biomarkers were assessed in GSE7305, and biomarker expression levels were further validated using qRT-PCR and western blot. We identified DEGs between high and low expression groups of key biomarkers. Enrichment analysis was carried out to discover the target gene’s biological function. We analyzed the relationship between key biomarker expression and patient clinical features. Finally, the immune cells that infiltrate endometriosis were assessed using the Microenvironment Cell Population-Counter (MCP-counter), and the correlation of biomarker expression with immune cell infiltration and immune checkpoints genes was studied. Results: There were a total of 38 DEGs discovered. Two machine learning techniques were used to identify 10 genes. Six biomarkers (SCG2, ASPN, SLIT2, GEM, EGR1, and FOS) had good diagnostic efficiency (AUC > 0.7) by internal and external validation. We excluded previously reported related genes (SLIT2, EGR1, and FOS). ASPN was the most significantly differentially expressed biomarker between normal and ectopic endometrial tissues, as verified by qPCR. The western blot assay revealed a significant upregulation of ASPN expression in endometriotic tissues. The investigation for DEGs in the ASPN high- and low-expression groups revealed that the DEGs were particularly enriched in extracellular matrix tissue, vascular smooth muscle contraction, cytokine interactions, the calcium signaling pathway, and the chemokine signaling pathway. High ASPN expression was related to r-AFS stage (p = 0.006), age (p = 0.03), and lesion location (p < 0.001). Univariate and multivariate logistic regression analysis showed that ASPN expression was an independent influencing factor in patients with endometriosis. Immune cell infiltration analysis revealed a significant increase in T-cell, B-cell, and fibroblast infiltration in endometriosis lesions; cytotoxic lymphocyte, NK-cell, and endothelial cell infiltration were reduced. Additionally, the percentage of T cells, B cells, fibroblasts, and endothelial cells was favorably connected with ASPN expression, while the percentage of cytotoxic lymphocytes and NK cells was negatively correlated. Immune checkpoint gene (CTLA4, LAG3, CD27, CD40, and ICOS) expression and ASPN expression were positively associated. Conclusions: Increased expression of ASPN is associated with immune infiltration in endometriosis, and ASPN can be used as a diagnostic biomarker as well as a potential immunotherapeutic target in endometriosis.

Endometriosis and Impaired Placentation: A Prospective Cohort Study Comparing Uterine Arteries Doppler Pulsatility Index in Pregnancies of Patients with and without Moderate-Severe Disease.

The aim of this study was to evaluate if moderate-severe endometriosis impairs uterine arteries pulsatility index (UtA-PI) during pregnancy when compared to unaffected controls. In this prospective cohort study, pregnant women with stage III–IV endometriosis according to the revised American Fertility Society (r-AFS) classification were matched for body mass index and parity in a 1:2 ratio with unaffected controls. UtA-PIs were assessed at 11–14, 19–22 and 26–34 weeks of gestation following major reference guidelines. A General Linear Model (GLM) was implemented to evaluate the association between endometriosis and UtA-PI Z-scores. Significantly higher third trimester UtA-PI Z-scores were observed in patients with r-AFS stage III–IV endometriosis when compared to controls (p = 0.024). In the GLM, endometriosis (p = 0.026) and maternal age (p = 0.007) were associated with increased third trimester UtA-PI Z-scores, whereas conception by in-vitro fertilization with frozen-thawed embryo transfer significantly decreased UtA-PI measures (p = 0.011). According to these results, r-AFS stage III–IV endometriosis is associated with a clinically measurable impaired late placental perfusion. Closer follow-up may be recommended in pregnant patients affected by moderate-severe endometriosis in order to attempt prediction and prevention of adverse pregnancy and perinatal outcomes due to a defective late placental perfusion.

Pregnancy outcomes after in vitro fertilization for moderate and severe endometriosis. A case-control study

IntroductionPrevious international studies showed that endometriosis could have a link with obstetrical complications, as an increased risk of preterm birth, gestational diabetes mellitus, and cesarean section. However, the results are difficult to interpret because biases are common, such as heterogeneity in the severity of the endometriosis cases included. That's why some complications as risk of miscarriage and post-partum hemorrhage are still debated. Our objective was to study pregnancy outcome after In Vitro Fertilization (IVF) in women suffering from rAFS stage III and IV endometriosis. MethodsWe conducted a case-control study between 2009 and 2019. We compared pregnancy outcomes after IVF in two groups of women matched by age, body mass index and smoking in two hospital centers. Group A was constituted by singleton pregnancies following ART for moderate and severe endometriosis (rAFS stage III and IV endometriosis). Group B was composed of singleton pregnancies in women with no endometriosis following ART for another reproductive disease. All women achieved pregnancy after 22 weeks. ResultsA total of 240 pregnant women were included: 80 singleton IVF pregnancies (group A) were compared with 160 singleton IVF pregnancies (group B). We observed an increased risk of placenta previa (12.5% Vs 1.9%; p = 0,001), and cesarean section (49.4% (n = 39) Vs 29.6% (n = 47) p = 0,004). Rate of postpartum hemorrhage was not significantly different in endometriosis group (11.2% Vs 7.5% p = 0.47). ConclusionDespite conflicting results in literature due to a lot of confounding variables, the impact of endometriosis on pregnancy is still debated in women suffering from rAFS III and IV endometriosis. In our study, we observed statistically higher rates of placenta previa and cesarean section but not an increased risk of postpartum hemorrhage. Further larger series are needed to confirm our findings and a possible link with other obstetrical complications. However, we think that an ART pregnancy in a context of severe endometriosis should be considered at risk of adverse obstetrical outcomes.

Ovarian Immobility at Transvaginal Ultrasound: An Important Sonographic Marker for Prediction of Need for Pelvic Sidewall Surgery in Women With Suspected Endometriosis.

To determine whether ovarian fixation at transvaginal ultrasound (TVU) is a marker for a need for laparoscopic pelvic sidewall surgery (ie,ureterolysis or dissection of adhesions involving the pelvic sidewall). The relationship between ovarian immobility at TVU with respect to endometriosis staging using the revised American Fertility Society (r-AFS) classification was also evaluated. Retrospective diagnostic accuracy study was performed in a tertiary referral hospital and two private hospitals. Sixty-six women with pelvic pain underwent detailed TVU preoperatively followed by laparoscopic endometriosis surgery. TVU ovarian mobility findings (ie, mobile versus fixed ovary) were compared to surgical findings, the need for laparoscopic pelvic sidewall surgery and r-AFS score (I-IV). Complete ultrasound and surgical data were available for 66 of 77 (86%) women. Twenty-six of 66 (40%) had isolated superficial peritoneal endometriosis, 15 of 66 (23%) had ovarian endometrioma (OE), 13 of 66 (20%) had pelvic deep endometriosis (DE). Twenty-seven of 66 (41%) had ovarian fixation at TVU. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of ovarian fixation at TVU for the prediction of need for laparoscopic pelvic sidewall surgery was 71%, 61%, 86%, 85%, and 62%, respectively (P=.0002). Ovarian fixation at TVU was significantly associated with the presence of ipsilateral OE, pouch of Douglas obliteration, pelvic DE nodules, and r-AFS stage III/IV (moderate/severe) endometriosis (all P-values <.05). Ovarian fixation at TVU appears to be a marker for moderate/severe endometriosis and the need for laparoscopic pelvic sidewall surgery. This sign may be a valuable "red flag" for identifying women at increased risk of requiring an advanced laparoscopic surgeon, and in turn, improve surgical planning.

P–454 Oocyte vitrification for fertility preservation in women with benign gynecological disease: French national clinical guidelines with a modified Delphi consensus process

Abstract Study question Is there consensual clinical practices about fertility preservation (FP) for benign gynecological diseases BGD)? Summary answer A consensus study using the modified Delphi method identified 28 consensual practices concerning oocyte vitrification for fertility preservation in women with benign gynecological disease. What is known already Clinical Practical international guidelines are still published in oncology for offering standardized information and care for adults and children with cancer. Recently, the ESHRE Female Fertility Preservation Guideline Development Group published recommendations for healthcare professionals involved in fertility preservation for post-pubertal women and transgender adolescents and young adults. However, benign gynecological indications weren’t distinctly individualized of malignant conditions. There’s a lack of large cohort studies assessing the risks and outcome of FP for benign gynecological diseases. Healthcare professionals need consensus for defining the “good” indications of FP for benign gynecological diseases that could impair fertility. Study design, size, duration A steering group composed by 14 healthcare professionals and a patient representative with lived experience of endometriosis identified 42 potential practices concerning fertility preservation for benign gynecological disease. Then, 114 key stakeholders including various healthcare professionals (n = 108) and patient representatives(n = 6) were asked to answer at two rounds of a modified Delphi via an online survey from February to September 2020. Participants/materials, setting, methods Participants had to score 42 items for the first round and 31 for the second round using a nine-point Likert scale. These statements were distributed into five categories: Information to deliver to age-reproductive women with a BGD (n = 9), technical aspect of fertility preservation for BGD (n = 6), indications of FP for endometriosis (n = 13), indications of FP for none-endometriosis BGD (n = 10), idiopathic diminished ovarian reserve in the absence of gynecologic and endocrinologic diseases (n = 4). Main results and the role of chance Survey response of stakeholders was 75% (86 out of 114) for the round 1 and 87% (75 out of 86) for the round 2. Consensus recommendations were achieved for 28 items, and no consensus between stakeholders was achieved in the remaining items. Stakeholders rated the importance of an age-specific information concerning the risk of diminished ovarian reserve after surgery and the necessity to inform about the benefice/ risk balance of oocyte vitrification, in particular about the chance of live-birth according to the age at the time of oocyte vitrification. They endorsed oocyte vitrification as the reference FP technique for those benign indications. Experts rejected to determine lower and upper age limits in women for fertility preservation. FP shouldn’t be offered in rAFS stages I and II endometriosis without endometriomas. Limitations, reasons for caution Experts were only French native speakers from France, and Belgium. It would have been interesting to conduct this survey with experts from other continents. Wider implications of the findings: At our knowledge, we present here the first guideline s focusing on FP in women with BGD, following a designed scientific Delphi procedure. These guidelines could be useful for gynecologists to better inform women with benign gynecological diseases about the indication or not to offer a FP procedure.

Patterns of Immune Infiltration in Endometriosis and Their Relationship to r-AFS Stages.

Background: Endometriosis (EMS) is an estrogen-dependent disease in which endometrial glands and stroma arise outside the uterus. Current studies have suggested that the number and function of immune cells are abnormal in the abdominal fluid and ectopic lesion tissues of patients with EMS. The developed CIBERSORT method allows immune cell profiling by the deconvolution of gene expression microarray data.Methods: By applying CIBERSORT, we assessed the relative proportions of immune cells in 68 normal endometrial tissues (NO), 112 eutopic endometrial tissues (EU) and 24 ectopic endometrial tissues (EC). The obtained immune cell profiles provided enumeration and activation status of 22 immune cell subtypes. We obtained associations between the immune cell environment and EMS r-AFS stages. Macrophages were evaluated by immunohistochemistry (IHC) in 60 patients with ovarian endometriomas.Results: Total natural killer (NK) cells were significantly decreased in EC, while plasma cells and resting CD4 memory T cells were increased in EC. Total macrophages in EC were significantly increased compared to those of EU and NO, and M2 macrophages were the primary macrophages in EC. Compared to those of EC from patients with r-AFS stage I ~ II, M2 macrophages in EC from patients with stage III ~ IV were significantly increased. IHC experiments showed that total macrophages were increased in EC, with M2 macrophages being the primary subtype.Conclusions: Our data demonstrate that deconvolution of gene expression data by CIBERSORT provides valuable information about immune cell composition in EMS.

Relationship between serum brain-derived neurotrophic factor and clinical stage and dysmenorrhoea of enodmetriosis

Objective: To explore the association between serum brain-derived neurotrophic factor and clinical stage and dysmenorrhoea of endometriosis. Methods: A total of 82 patients were studied with laparoscopically diagnosed endometriosis between June 2017 and June 2019, and 75 healthy women with reproductive age were selected as the control group during the same period. The endometriosis patients were scored by visual analogue scale(VAS)according to their preoperative dysmenorrhoea.And endometriosis was staged and scored according to the score of Revised American Fertility Society(r-AFS).Enzyme-linked immunosorbent assay (ELISA) was used to determine preoperative BDNF level in serum, and the correlation between BDNF level with clinical stage as well as dysmenorrhea of endometriosis were analysed. Results: The serum BDNF level in endometriosis patients was (1 082±43) ng/L, significantly higher than that in the normal control [(649±30) ng/L], there was statistical difference between the two groups(P<0.001). The BDNF expression in patients with r-AFS stage Ⅲ-Ⅳ was higher than that in patients with Ⅰ-Ⅱ stage [(1 164±389) ng/L vs (791±218)ng/L, P<0.001]. BDNF level in serum was closely correlated with the degree of dysmenorrhea (r=0.682), and the BDNF level in patients with moderate or severe dysmenorrhea was significantly higher than that in patients without dysmenorrhea and patients with mild dysmenorrhea [(1 292±43) ng/L vs(718±36) ng/L, P<0.001]. Conclusions: The serum BDNF level in endometriosis patients is positively correlated with clinical stage and dysmenorrhea.

2852 Long Term Follow up of Carbon Dioxide Laser Vaporisation Versus Harmonic Scalpel Excision in the Treatment of Superficial Endometriosis: A Randomised Controlled Trial

Study Objective To evaluate if excision of endometriosis (rAFS stages I-III) with the harmonic scalpel, is superior to carbon dioxide laser vaporisation in terms of symptoms over a 3 year period. Design This was a randomized double blind controlled trial. Setting Set at a Tertiary referral unit. Patients or Participants 116 patients found to have endometriosis at laparoscopy were randomized in to the study. Interventions The study was powered for superiority, and patient's randomized with a 1:1 allocation into receiving treatment either with laser or harmonic scalpel. Data was analyzed using SPSS version 21. The primary outcome measure was the visual analogue scale (VAS) score for chronic pelvic pain score at 6 months. Secondary outcomes included core EHP-30, HADS anxiety and depression score and VAS scores for chronic pelvic pain, dysmenorrhoea, dyschezia and dyspareunia, up to 3 years. Measurements and Main Results Pre operative chronic pelvic pain (VAS) for the laser and harmonic groups were 57.1 (IQR: 28.1-75.6) and 50.6 (IQR: 0-75.0) respectively, and at 6 months 43 (IQR: 0-66.5) and 30 (IQR: 0-60.7). The difference between the two were not statistically significant, p=0.228. At 12 months the chronic pelvic pain VAS scores for laser and harmonic groups were 50 (IQR: 20-74.7) and 13.1 (IQR: 0-49.0) respectively. The difference between the two was significant, p Conclusion Excision of endometriosis with harmonic is effective at improving chronic pelvic pain up to 3 years. This does not appear to be the case with CO2 laser vaporisation. In terms of most secondary outcomes laser performs as well as harmonic at 6 months but the trend is in favor of harmonic up to 3 years.

Analysis of the Predictive Factors for the Recurrence of Deep Infiltrating Endometriosis: A 2-Year Prospective Study

Objective: To investigate factors that may be associated with the recurrence of deep infiltrating endometriosis (DIE) and DIE-related symptoms. Methods: Starting in September 2014, women with a confirmed diagnosis of DIE based on surgical and histological findings were included in the prospective study with a 2-year follow-up in our hospital. A total of 84 consecutive patients were included, all of whom underwent laparoscopic surgery. The data were obtained from the medical records of the patients. Follow-up data, including presence of pain as assessed using the visual analog scale (VAS) score and ultrasonography/magnetic resonance imaging findings, were obtained at 3, 6, 9, 12, and 24 months postoperatively. Variables, such as age, body mass index, severity and duration of symptoms, size and location of the lesion, and pre- and postoperative medical treatment, were evaluated using univariate and multivariate analyses to identify factors correlated to recurrence. Results: A total of 11 (13.1%) patients presented with recurrence, with a mean time to recurrence of 14.2 months. The univariate analysis showed that the longer duration of menstruation (7.4 vs. 6.0, P = 0.010), the more advanced revised American Fertility Society (rAFS) stage (Stages I and II vs. III and IV, χ2 = 9.964, P = 0.001), the higher VAS score for dysmenorrhea (9.4 vs. 5.2, P = 0.001), and the more severe pain during defecation (7.8 vs. 4.8, P = 0.016) were positively correlated to DIE recurrence. However, the multivariate analysis also revealed that a more severe dysmenorrhea and advanced rAFS stage were the independent factors associated with the recurrence of DIE, with an odds ratio of 1.895 (confidence interval [CI]: 1.061–3.385, P = 0.031) and 4.310 (CI: 1.091–17.028, P = 0.037), respectively. Conclusions: More than 10% of patients presented with recurrence of DIE 2 years after surgery. Recurrence of DIE was more common in patients who complained of more severe dysmenorrhea and had an advanced rAFS stage.

Ureteral endometriosis in patients with deep infiltrating endometriosis: characteristics and management from a single-center retrospective study.

As a serious type of deep infiltrating endometriosis (DIE), ureteral endometriosis (UE) can result in decreased kidney function. The aims of this study are to investigate risk factors and surgical treatments for UE. The study enrolled 329 patients with deep infiltrating endometriosis, who were treated with laparoscopic surgery between January 2014 to September 2018. All patients were divided into one of two groups: UE or non-UE. Clinical information and other surgery variables of the two groups were examined. Out of 329 patients with DIE, 68 (20.67%) cases of UE were diagnosed. Among them, 37 patients also had hydroureteronephrosis. In a multivariate analysis, the variables revised American Fertility Society (rAFS) stage IV, uterosacral ligament (USL) DIE lesion ≥ 3cm in diameter and previous surgery for endometriosis significantly increased the risk of UE. A total of 27.03% (10/37) of patients with UE and hydroureteronephrosis showed decreased kidney function. Ureterolysis was performed in 59 patients, and an ureteroneocystostomy was performed in 9 patients. A double-J stent was placed in 37 patients with UE. Only 1 patient developed acute pyelonephritis postoperatively. During more than 2years of follow-up, no patient experienced recurrence. The variables of rAFS stage IV, USL DIE lesion ≥ 3cm in diameter and previous surgery for endometriosis significantly increased the risk of UE. Laparoscopic ureterolysis and ureteroneocystostomy are feasible and safe procedures with low complication and recurrence rates.

The Prevalence of Incidental Endometriosis in Women Undergoing Laparoscopic Ovarian Drilling for Clomiphene-Resistant Polycystic Ovary Syndrome: A Retrospective Cohort Study and Meta-Analysis.

To evaluate the incidence of endometriosis in polycystic ovary syndrome (PCOS) patients who did not present with any endometriosis symptoms and underwent laparoscopic ovarian drilling (LOD) for clomiphene citrate (CC) resistance, 225 and 630 women with CC-resistant PCOS without classic endometriosis symptoms were included in a retrospective study and a meta-analysis, respectively. All women underwent LOD. The main outcome parameter was the prevalence of incidental endometriosis. Laparoscopy revealed endometriosis in 38/225 (16.9%) women (revised American Fertility Society (rAFS) stage I: 33/38, 86.8%; rAFS stage II: 5/38, 13.2%). When women with CC-resistant PCOS without endometriosis were compared, lower body mass index (BMI) and lower 25-hydroxy-vitamin D levels were associated with the presence of endometriosis at laparoscopy (odds ratios (OR): 0.872, 95% confidence intervals (95%CI): 0.792–0.960; p = 0.005 and OR: 0.980, 95%CI: 0.962–0.999; p = 0.036; respectively). The inclusion criteria for the meta-analysis were fulfilled by 4/230 reports about LOD. After correction for study heterogeneity, the pooled prevalence of incidental endometriosis was 7.7% in women with CC-resistant PCOS. In conclusion, the rate of incidental endometriosis in women with CC-resistant PCOS might reflect the prevalence of asymptomatic endometriosis. All cases were affected by minimal or mild disease. Since the literature lacks reports on associated clinical outcomes, the relevance of this entity in such patients should be the subject of further studies.

Expression and role of hScrib in endometrium, endometriosis, and endometrial adenocarcinoma.

To explore the role of hScrib in the pathogenesis of endometriosis.This was a retrospective study of 240 women in our hospital between January 2014 and January 2017. The expression of hScrib in endometrium (EM), endometriosis (EMs), and endometrial adenocarcinoma (EC) was investigated, and compared the differences among them. Serum levels, protein expressions, localizations, and correlations of hScrib and E-cadherin were determined.The levels of serum soluble hScrib and E-cadherin were significantly highest in EC, followed by EMs, and healthy women (P < .05). hScrib protein content was opposite result in 3 tissues (P < .05), and was negatively correlated with r-AFS stage in EMs. The location changed from membrane to cytoplasm. Co-localization of hScrib with E-cadherin was found at extensive cell–cell boundaries in EMs.hScrib and E-cadherin may be as new diagnostic markers of endometriosis. Low expression of hScrib leads to the loss of cell polarity and stability. Also, hScrib may induce EMT through regulating E-cadherin, might play an important role in pathogenesis of endometriosis.

Effect of gonadotropin-releasing hormone agonist used before surgery on natural pregnancy rates in patients with ovarian endometriomas

Objective: To evaluate the impact of gonadotropin-releasing hormone agonist (GnRH-a) used before surgery on natural pregnancy rates in patients with ovarian endometriomas. Methods: In this retrospective study, 57 patients with ovarian endometriomas who had a consecutive laparoscopic surgery between June, 2010 to September, 2015 in Peking Union Medical College Hospital were included. Those patients were divided into preoperative GnRH-a treatment group (n=31) and non-GnRH-a treatment group (n=26) . There were no differences in patients' characteristics between the two groups. All of them had a desire for natural pregnancy postoperatively. GnRH-a was no longer used after surgery. After the surgical procedure, the patients were observed over a period of 12 months, during which the frequency of natural pregnancy was assessed. The two groups were compared in terms of natural pregnancy rates. Results: Totally 33 patients had natural pregnancy after surgery. The univariate analysis showed that the pregnancy rates of age, r-AFS stage, infertility, preoperative use of GnRH-a, tumor size, tumor side, deep infiltrating endometriosis and adenomyosis did not have statistically significant differences (all P>0.05) . The two classified logistic regression showed that OR for preoperative use of GnRH-a was 0.250 (95%CI: 0.064-0.978) with a statistical difference (P=0.046) . Conclusion: The use of GnRH-a preoperatively may have a negative effect on natural pregnancy rates of patients after surgery with ovarian endometriomas.

Use of the Endometriosis Fertility Index to Predict Natural Pregnancy after Endometriosis Surgery: A Single-Center Study

Aims: Our objective was to predict natural pregnancy after endometriosis surgery using the endometriosis fertility index (EFI). Methods: A retrospective medical records review was conducted, examining patients surgically treated for endometriosis at a single center in Korea between January 2009 and February 2015. In total, 68 women attempting natural conception were analyzed by assessing age, preoperative serum CA-125, body mass index, revised American Fertility Society (rAFS) stage, EFI, and pregnancy outcome. Kaplan-Meier estimates and log-rank tests were used to generate cumulative natural pregnancy rate curves based on an EFI cut-point. A receiver-operating characteristic (ROC) curve was plotted for EFI. Results: Seventy-seven patients attempted conceptions, resulting in 33 natural and 9 assisted conceptions. Excluding assisted conceptions, the mean EFI scores of 68 women who were not pregnant and pregnant were 5.43 ± 0.36 and 6.88 ± 0.28 respectively. The relation between EFI and natural pregnancy was significant (cumulative overall pregnancy rate, p = 0.006), whereas rAFS stage was not (univariate logistics, p = 0.853). The cut-point for maximum natural pregnancy outcomes was 6 (area under ROC curve = 0.710, 95% CI 0.586–0.835). Conclusion: The EFI is a reliable staging system for predicting natural pregnancy after endometriosis surgery. EFI scores can be used to guide postoperative treatment of women with endometriosis.

Pregnancy Outcome in Infertility Patient with Endometriosis Cyst after Laparoscopic Cystectomy

Objective: To investigate about the rate of pregnancy in womenwho had undergone laparoscopic cystectomy.Methods: This was a retrospective study. Data were taken from themedical records of patients with infertility in Fatmawati Hospital,Jakarta, Indonesia. Data then analyze to know is there anyassociation between age, infertility duration, bilaterality of the cyst,tubal patensy, r-AFS stage with pregnancy rate.Results: A total of 64 subjects were recruited in this study. Therewere 23 subjects (35.9%) that got pregnant within one year afterundergoing laparoscopic procedure. Those who were 35 years oldor less had a greater chance to get pregnant (p = 0.01, OR = 6.75),duration of infertility  3 years had a greater chance to getpregnant with OR = 3.2 and p value = 0.032, r-AFS stage II and IIIhad a greater chance to get pregnant to with (p = 0.04, OR = 3.25and 4.25).Conclusion: The pregnancy rate after laparoscopic procedure is35.9% in this study. There are correlation between age, durationof infertility, and r-AFS staging with pregnancy rate.[Indones J Obstet Gynecol 2018; 6-1: 34-38]Keywords: endometriosis, infertility, laparoscopy, pregnancy

Expression of MTA1 in endometriosis and its relationship to the recurrence.

Metastasis-associated gene 1 (MTA1) is correlated with prognosis of many tumors. However, little is known about the role of MAT1 in endometriosis and its relationship with the recurrence of endometriosis.The expression of MTA1 in normal, eutopic and ectopic endometrium was detected by immunohistochemistry and RT-PCR, respectively. The relationship of MTA1 expression with the recurrence of endometriosis was evaluated.In the normal endometrium, eutopic endometrium and ectopic endometrium, the positive rates of MTA1 expression showed a gradually increasing trend. In addition, the MTA1 expression difference between each two groups was significant (P < .0125). However, there was no significant difference between proliferative phase and secretory phase in each group (P > .05). In the ectopic endometrium, MTA1 expression in the severe phases (III-IV) was significantly higher than that in mild phases (I-II) (P < .05), indicating the expression of MTA1 correlates with r-AFS staging (P < .05). Additionally, the MTA1 mRNA level was also closely related to the stages of r-AFS, but not to the proliferative phase or secretory phase of endometrium. Logistic regression analysis showed that r-AFS stage and MTA1 overexpression were risk factors for the recurrence of endometriosis. While, postoperative pregnancy was a protective factor for its relapse.MTA1 is closely associated with the occurrence and development of Ems. Thus, MTA1 level may be used as a new indicator to predict the progression of endometriosis.

Expression of MMIF, HIF-1α and VEGF in Serum and Endometrial Tissues of Patients with Endometriosis.

The aim of this study was to investigate the expression of macrophage migration inhibitory factor (MMIF), hypoxia-inducible factor-1 a (HIF-1α) and vascular endothelial growth factor (VEGF) in the serum and endometrial tissues of patients with endometriosis (EM) and the clinical significance. Eighty EM patients [American Reproductive Association stage I (n=20), stage II (n=22), stage III (n=21) and stage IV (n=17)] were enrolled and divided into mild (10-14 points, n=28), moderate (16-24 points, n=27) and severe (26-30 points, n=25) dysmenorrhea groups. The control group included 40 healthy women of childbearing age who underwent routine healthcare examinations in the enrolment period. The expression of MMIF, HIF-1α and VEGF in the serum and endometrial tissues was measured by enzyme-linked immunosorbent assay and Western blotting, respectively. Meanwhile, the sensitivity and specificity of serum MMIF, HIF-1α, and VEGF when separately used as single indexes or jointly used as one index were examined as well. The results showed that serum concentrations of MMIF, HIF-1α, and VEGF were significantly higher in EM patients than in controls (P<0.05). The expression of all three proteins in both serum and endometrial tissues increased significantly with the R-AFS stage (P<0.05) and with dysmenorrheal severity (P<0.05). The sensitivity and specificity of the combined detection of serum MMIF, HIF-1α, and VEGF levels were significantly higher than those of single index detection (P<0.05). In conclusion, the expression of MMIF, HIF-1α, and VEGF in the serum and endometrial tissues may be used to assess the stage of EM and the severity of dysmenorrhea. Combined evaluation of MMIF, HIF-1α, and VEGF significantly improves the diagnostic sensitivity and specificity.
