The Visual Effect of a Down-Regulation With Dienogest and GnRH Analogues in Endometriosis: Lessons Learned From Two-Step Surgical Approach.

OBJECTIVE: To evaluate the intraoperative visual effect of treatment with GnRH-analogues and Dienogest in endometriosis. DESIGN: Retrospective observational study. SETTING: Every laparoscopy from all the different disciplines in our hospital is documented on video and stored in a database. The study was approved by the local ethics committee. A total of 193 patients with histological proven endometriosis from 2007 to 2021 were included, who underwent 2-step surgical procedure. Indications were endometrioma before CO2-Laser therapy, missing consent because of emergencies or other surgeries from other disciplines, or high active and extended disease. When endometriosis was suspected in a surgery conducted by other disciplines, a gynecological surgeon was called during the surgery. Data and intraoperative videos were reviewed by 2 independent reviewers at one referral center. Only cases with available video of first and second look laparoscopy were included. We excluded patient who had prior hormonal treatment in the last 6 months. Lesions were classified according to the description of Khan et al. Statistical analysis was performed using SPSS (Version 27.0, IBM). Mann-Whitney U test (nonparametric analysis) and χ2 tests were applied. Percentages were calculated for categorical variables and mean and standard deviation were calculated for continuous variables. Significance level was set to p <.05. INTERVENTIONS: Seventy-seven received GnRH-analogues and 116 Dienogest for preoperative hormone down-regulation. The median duration of down-regulation with GnRH-analogues or Dienogest was 3 months. The mean age was 32.3 (SD 6.3) years for GnRH-analogues and 32.6 (SD 6.3) years for Dienogest, p = .619 respectively. The visible intraoperative effect will be demonstrated in the video. CONCLUSION: The effect of a hormonal treatment can be observed macroscopically in endometriosis. This can help to understand the in vivo response to the administrated treatment. This video is showing our past experience, as performing second-look laparoscopy is not state of the art anymore.

Co-Existence of Endometriosis with Ovarian Dermoid Cysts: A Retrospective Cohort Study.

Both endometriosis and ovarian dermoid cysts are benign conditions characterized by the presence of well-differentiated tissues in ectopic locations. The presence and surgical excision of these entities can potentially impact ovarian reserves, contributing to reduced chances of future pregnancy. The objective of our study is to investigate the bidirectional association between endometriosis and ovarian dermoid cysts, as well as to analyze the clinical characteristics of patients diagnosed with both conditions. A retrospective cohort study was conducted, including women who underwent laparoscopy and received histological diagnoses of endometriosis and/or dermoid cysts between 2011 and 2019 at the Cantonal Hospital of Schaffhausen. We identified 985 women with endometriosis and 83 women with ovarian dermoid cysts. Among these groups, 22 women presented with both endometriosis and ovarian dermoid cysts. The majority of the above patients had endometriosis stage rASRM I-II (72.7%), with peritoneal endometriosis being the most common phenotype of endometriosis (77.2%). Out of the 14 patients with a desire for future pregnancy, the majority (11/14, 78.5%) had an EFI score of 7-8. The prevalence of bilateral ovarian dermoid cysts was higher in women with both ovarian dermoid cysts and endometriosis in comparison to women with ovarian dermoid cysts without endometriosis (18% vs. 6.5%). Our study revealed that 26.5% of women with ovarian dermoid cysts also had endometriosis, a notably higher prevalence than observed in the general population. Clinicians should be aware of this co-existence, and preoperative counseling should be an integral part of the care plan for affected individuals, where the potential risks and the available options for fertility preservation should be discussed in detail.

Dysmenorrhea in adolescents requires careful investigation of endometriosis-an analysis of early menstrual experiences in a large case-control study.

Introduction: Recent evidence shows that endometriosis, a significant cause of infertility, may already present in adolescents. Dysmenorrhea, often leading to school absences, is a key symptom of the maturing menstrual cycle but also of endometriosis. However, it is often perceived as "normal" and left untreated. In adolescents, laparoscopy, the standard procedure to diagnose endometriosis, is performed particularly cautiously. To improve reproductive health in adolescents, we evaluate associations between early menstrual experiences and endometriosis. Methods: Retrospective data on early menstrual experiences from 563 women with surgically/histologically verified endometriosis and from 563 age-matched controls were compared. Study participants were recruited in Switzerland, Germany, and Austria. Information on menstrual experiences was collected via a structured questionnaire. Results: The bivariate analysis showed that early menarche (p = 0.004), dysmenorrhea and negative memories of menarche (p < 0.001) were significantly associated with a diagnosis of endometriosis. After controlling for confounders in bivariate regression analysis occurrence of dysmenorrhea (p = <0.001, OR 5,74, 95% CI 3.82-7.22) especially with onset >3 years after menarche ((p = <0.001, OR 3.42, 95% CI 2.09-5.64) remained statistically significant predictors for diagnosis of endometriosis. Dysmenorrhea in mothers and mothers' perceived attitude towards menstruation were not associated with the occurrence of Endometriosis. Conclusions: Dysmenorrhea and onset of dysmenorrhea at menarche or several years after it are strongly associated with the development of endometriosis. As mothers perceived attitudes towards menstruation show no significant association with their daughters' experiences, physical symptoms accompanying menarche and menstrual period pain in adolescents seem to be very reliable predictors in diagnosis of endometriosis. Therefore, dysmenorrhea in adolescents requires careful investigation of possible endometriosis, especially if it does not respond to medical management. Clinical trials registration: The study was registered on ClinicalTrials.gov, identifier (NCT02511626).

Physical Activity in Women with Endometriosis: Less or More Compared with a Healthy Control?

BACKGROUND: Endometriosis, i.e., endometrial-like tissue outside the uterus, is a chronic inflammatory condition affecting physical functioning. However, the specific levels of physical activity (PA) in the context of endometriosis and different disease symptoms remain unclear. METHODS: This multi-center, cross-sectional study compared PA levels and influencing factors in endometriosis patients and non-endometriosis patients. Data were collected through questionnaires. Endometriosis was surgically confirmed. A statistical analysis was performed with appropriate tests. RESULTS: The study included 460 women with endometriosis and 460 age-matched women without this condition. The two groups did not differ significantly in terms of age, education level, or stable partnership. Women with endometriosis exhibited lower PA levels, practicing fewer hours of sports weekly and climbing fewer stairs daily compared to the control group. These differences remained significant after controlling for confounding factors. Factors such as endometriosis, current dysmenorrhea, and depression were associated with decreased PA. CONCLUSIONS: These findings suggest that women with endometriosis engage in less PA compared to those without this condition. These results highlight the need for interventions to promote increased PA in endometriosis patients and harness the associated health benefits. Further research is warranted to explore the underlying mechanisms and develop tailored exercise therapies for this population.

Treatment after endometrioma recurrence: a narrative review.

INTRODUCTION: Ovarian endometrioma is a common subtype of endometriosis with a prevalence between 17 and 44%. The reported average recurrence of endometrioma after surgical management is 21.5% after 2 years and 40-50% after 5 years. The aim of this narrative review was to summarize the existing literature focusing on treatment options after endometrioma recurrence in order to provide an evidence-based approach for the clinical practice. EVIDENCE ACQUISITION: Three electronic databases (MEDLINE, EMBASE and Cochrane) were searched until September 2022 for eligible studies. EVIDENCE SYNTHESIS: The available studies showed that repeated surgery has a negative impact on ovarian function, without improving the fertility outcomes. Transvaginal aspiration as an alternative option for surgery has a high rate of recurrence, which varies from 8.20 to 43.5% depending on the technique used and on the study population. Pregnancy related outcomes were similar between transvaginal aspiration groups and no intervention groups in patients with endometrioma recurrence. Regarding medical treatments, only four studies were found, showing that progestins reduce the pain and the diameter of the ovarian cyst. CONCLUSIONS: Recurrent endometrioma is a challenging condition which could be encountered during the care of women with endometriosis. The decision about the treatment-strategy has to be individualized considering family planning status, age, ovarian reserve and transvaginal ultrasound findings. Well-designed randomized clinical trials are needed to export safer conclusions about the most appropriate treatment in each specific condition after endometrioma recurrence.

Intraoperative Appearance of Endosalpingiosis: A Single-Center Experience of Laparoscopic Findings and Systematic Review of Literature.

Background: Endosalpingiosis is assumed to be the second most common benign peritoneal pathology after endometriosis in women. Although recent studies indicate a significant association with gynecologic malignancies, many underlying principles remain unclear. This work aimed to systematically describe the intraoperative appearance of endosalpingiosis. Methods: Data and intraoperative videos of patients with histologically verified endosalpingiosis were retrospectively reviewed. The main outcome measures were macroscopic phenotype and anatomical distribution. Additionally, a systematic review searching PubMed (Medline) and Embase was conducted. Results: In the study population (n = 77, mean age 40.2 years (SD 16.4)), the mean size of lesions was 3.6 mm and the main visual pattern was vesicular (62%). The most frequent localization was the sacrouterine ligaments (24.7%). In the systematic review population (n = 1174 (210 included studies overall), mean age 45.7 years (SD 14.4)), there were 99 patients in 90 different studies with adequate data to assess the appearance of the lesions. The mean size of the lesions was 48.5 mm, mainly with a cystic visual pattern (49.5%). The majority of the lesions affected the ovaries (23.2%), fallopian tubes (20.4%), or lymph nodes (18.5%). Comparing this study to the literature population, the main differences concerned the size (p < 0.001) and main visual patterns (p < 0.001) of lesions. Conclusions: The usual intraoperative findings of endosalpingiosis appeared less impressive than described in the literature. In our study population, lesions of a few millimeters in size with a vesicular appearance were mostly seen, most frequently in the sacrouterine ligament area. Intraoperative recognition by the gynecologic surgeon and histologic diagnosis should play an important role in further understanding this entity, scientifically and clinically.

Prospective Multicenter Trial Assessing the Impact of Positive Peritoneal Cytology Conversion on Oncological Outcome in Patients with Endometrial Cancer Undergoing Minimally Invasive Surgery with the use of an Intrauterine Manipulator : Positive Peritoneal Cytology Conversion and Its Association with Oncological Outcome in Endometrial Cancer.

BACKGROUND: Minimally invasive surgery is the standard approach in early-stage endometrial cancer according to evidence showing no compromise in oncological outcomes, but lower morbidity compared with open surgery. However, there are limited data available on the oncological safety of the use of intrauterine manipulators in endometrial cancer. PATIENTS AND METHODS: This prospective multicenter study included patients with endometrial cancer undergoing laparoscopic staging surgery with the use of an intrauterine manipulator. We obtained three different sets of peritoneal washings: at the beginning of the surgical procedure, after the insertion of the intrauterine manipulator, and after the closure of the vaginal vault. The rate of positive peritoneal cytology conversion and its association with oncological outcomes was assessed. RESULTS: A total of 124 patients were included. Peritoneal cytology was negative in 98 (group 1) and positive in 26 (group 2) patients. In group 2, 16 patients presented with positive cytology at the beginning of the surgery (group 2a) and 10 patients had positive cytology conversion during the procedure (group 2b). Recurrence rate was significantly different among the study groups, amounting to 9.2%, 25.0%, and 60.0% for groups 1, 2a, and 2b, respectively (p < 0.001). Group 1 showed the best recurrence-free and overall survival, followed by group 2a, while patients in group 2b had the worst oncological outcomes (p = 0.002 and p = 0.053, respectively). Peritoneal cytology was an independent predictor of recurrence and death on multivariable analysis. CONCLUSION: A total of 8.1% of patients with endometrial cancer undergoing minimally invasive surgery with intrauterine manipulation showed positive peritoneal cytology conversion associated with significantly worse oncological outcome.

Superficial papilloma of the ovary.

Superficial papilloma of the ovary is a rare benign ovarian finding, which was first described back in 1895. Here, we present the intraoperative and histological findings of a superficial papilloma of the ovary in a 59-year-old patient.

Living with endometriosis: Comorbid pain disorders, characteristics of pain and relevance for daily life.

BACKGROUND: Pain plays a central role in endometriosis. The complex relationship among pain characteristics, comorbid pain disorders and daily life represents a challenge for medical support. This multicentre cross-sectional case-control study analysed the association between endometriosis-related chronic pain and functions of daily life in 510 women with endometriosis, 265 (52%) who experienced chronic pain, either from endometriosis alone (N = 134, 26.3%) or in association with additional pain disorders (N = 131, 25.7%). METHODS: Self-administered questionnaires from the Brief Pain Inventory and the Pain Disability Index were used to investigate associations between pain characteristics (frequency, duration, intensity) and daily life. Also, associations between different endometriosis characteristics (rASRM stage, presence of adhesions, localisation of lesions) and pain were evaluated. RESULTS: Chronic pain is negatively associated with almost all (12/14) aspects of daily life investigated, including standing, walking, sitting, defaecation, sleep, sports activities, family and domestic responsibilities, sexuality, social functioning, professional life, mood, and joy of life. Altogether, 33.7% of women with chronic pain reported moderate and 27.5% severe limitations. Comorbid pain disorders resulted in significantly more limitations. The length of pain episodes showed a particularly important influence, especially for family/domestic responsibilities (OR 22.94, p < 0.001), professional life (OR 16.56, p < 0.001) and social functioning (OR 41.03, p < 0.001). CONCLUSIONS: Our data confirm that despite treatment, about 50% of women experience pain. Pain was associated with at least moderate negative effects on almost all areas of daily life; additional pain comorbidities increased limitations. Improving pain management is essential for improving quality of life in women with endometriosis. SIGNIFICANCE: The study provides an accurate overview of the impact of endometriosis-associated pain on daily life. This is important because pain plays a central role in women living with endometriosis, and despite modern therapies, many women continue to suffer from chronic pain. The detailed analysis of its impact with a comprehensive survey of all aspects of daily life in a very large study population is unique. We expect an improved understanding of consequences of pain to significantly advance medical support in these patients.

How and where to expect endosalpingiosis intraoperatively.

OBJECTIVE: To describe the anatomical distribution and intraoperative morphology of endosalpingiosis. DESIGN: Retrospective observational video study. SETTING: Data and intraoperative videos were reviewed by two independent reviewers at one referral center. The study was approved by the local ethics committee. PATIENT(S): A total of 77 patients with histologically proven endosalpingiosis from 2007-2020. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The primary endpoints were anatomical distribution and macroscopic phenotype. The secondary endpoints were demographic and clinical characteristics as well as associated diseases. RESULT(S): Of the 77 patients with endosalpingiosis, the mean age was 40.2 years (standard deviation, 16.4 years), mean body mass index 24.1 kg/m2 (standard deviation, 5.7 kg/m2), 59.7% (n = 46) were nulligravide, 70.1% (n = 54) nulliparous, 22.1% (n = 17) suffered of infertility, and 53.2% (n = 41) had at least one previous abdominal or vaginal surgery. Endometriosis was associated in 53.2 % (n = 41) and malignancies in 28.6% (n = 22, 7 endometrial cancers, 1 uterine carcinosarcoma, 8 borderline ovarian tumors, 5 epithelial ovarian cancers, and 1 yolk sac tumor of the ovary). Anatomic distribution and varying intraoperative phenotypes were demonstrated in the video presentation. CONCLUSION(S): In the majority of this population, endosalpingiosis was located in the pelvis. The higher prevalence of specific gynecologic tumors is consistent with previous results. In phenotype, most lesions appear to be less spectacular than prominent in the literature. For further studies on the relevance as a risk factor for malignancy and consequently clinical recommendations, sound knowledge about endosalpingiosis of laparoscopists as initial diagnosticians is crucial.

Treatment of endometriosis: a review with comparison of 8 guidelines.

BACKGROUND: Endometriosis, the presence of endometrial-like tissue outside the uterus, is a common clinical entity between women of reproductive age, with a prevalence of about 10%. Due to the variety of endometriosis-associated symptoms, a great variety of treatments have been implemented. The aim of this review is to give an overview on therapeutical approaches of eight national and international widely used guidelines. METHODS: Six national (College National des Gynecologues et Obstetriciens Francais, National German Guideline (S2k), Society of Obstetricians and Gynaecologists of Canada, American College of Obstetricians (ACOG) and Gynecologists, American Society for Reproductive Medicine (ASRM) and National Institute for Health and Care (NICE) and two international (World Endometriosis Society, European Society of Human Reproduction and Embryology) guidelines are included in this review. CONCLUSION: All the above-mentioned guidelines agree that the combined oral contraceptive pill, progestogens are therapies recommended for endometriosis associated pain. Concerning infertility, there is no clear consensus about surgical treatment. Discrepancies are also found on recommendation of the second- and third-line treatments.

[Endosalpingiosis - an Irrelevant Incidental Finding During Laparoscopy?] / Endosalpingiose ­ ein irrelevanter laparoskopischer Zufallsbefund?

Endosalpingiosis - an Irrelevant Incidental Finding During Laparoscopy? Abstract. Endosalpingiosis refers to the ectopic presence of tubal epithelium. However, this incidental finding received little attention, although it is the second most common benign peritoneal pathology in women following endometriosis. In contrast to endometriosis, endosalpingiosis shows an increase in prevalence with age beyond the menopause. Furthermore, it does not appear to be chronically inflammatory and, according to research to this date, does not cause chronic pain or infertility. Recent epidemiological and molecular pathological studies show a significantly higher incidence of ovarian and endometrial tumors in women with endosalpingiosis. These correlations have not been conclusively clarified. Generally accepted clinical recommendations for the detection of endosalpingiosis do not yet exist. In order to better understand the disease value of endosalpingiosis and its oncological correlations, this entity should be brought to the attention of surgical gynecology and involved pathology.

Qualitative and quantitative aspects of sex life in the context of endometriosis: a multicentre case control study.

RESEARCH QUESTION: What are the specific characteristics of sexual activity in women with endometriosis compared with women without endometriosis? DESIGN: Multicentre case control study. Participants were recruited from university hospitals, district hospitals and doctor's offices in Germany, Switzerland and Austria. A total of 565 women with endometriosis were pair-matched to 565 control women by age and ethnic background. Diagnosis of endometriosis was confirmed by histology, and disease stage was classified according to American Society for Reproductive Medicine criteria. Data on sexuality were collected using selected questions from the Brief Index of Sexual Function and the Sexual History Form. RESULTS: Altogether, 69.1% of women with endometriosis and 77.8% of control women engaged in sexual activity during the month before the study period (P < 0.001). Overall, 42.3% of endometriosis-affected women and 30.5% of the control women desired a higher frequency of sexual activity (P < 0.001). Petting, foreplay and vaginal sexual intercourse were reported to be practised less often by women with endometriosis. Frequencies for masturbation, reciprocal masturbation, oral and anal sex were similar in both groups. Dyspareunia was negatively associated with sexual activity (OR 2.42, 95% CI 1.26 to 4.63), whereas chronic pain showed no association with sexual activity (OR 1.35, 95% CI 0.93, 1.96). CONCLUSIONS: Women with endometriosis have lower frequencies of petting, foreplay and vaginal sexual intercourse than control women; this difference has to be attributed, at least in part, to dyspareunia. Potentially pain-free sexual options are used to a limited degree. As endometriosis-affected women desire higher levels of sexual activity, sexual counselling should be included in medical support.

The ENZIAN score as a preoperative MRI-based classification instrument for deep infiltrating endometriosis.

PURPOSE: Comparison of preoperative magnetic resonance imaging (MRI) with intraoperative findings in patients with deep infiltrating endometriosis (DIE) by means of the ENZIAN score. METHODS: This retrospective two-center study includes 63 patients with deep infiltrating endometriosis, who underwent surgery between 2012 and 2016 at both the University Hospital of Zurich and the Cantonal Hospital of Schaffhausen. Inclusion criteria were a preoperative pelvic MRI and intraoperative or bioptic confirmation of DIE. The preoperative MRI findings were compared with the intraoperative results by means of the ENZIAN score. Furthermore, the various MRI sequences were analyzed for their diagnostic value based on a Likert scale. RESULTS: Sensitivity and negative predictive values of MRI confirmed by surgery were 95.2% and 91.7% (lesions in the vaginal/rectovaginal space), 78.4% and 56% (uterosacral ligaments), 91.4% and 89.7% (rectum/sigmoid colon), 57.1% and 94.1% (myometrium), 85.7% and 98.3% (bladder), and 73.3% and 92.2% (intestine), respectively. T2 axial and sagittal MRI sequences in combination with a T1 sequence were diagnostically sufficient. CONCLUSIONS: The MRI-based ENZIAN score correlates well with the intraoperative findings, enabling a better planning of the surgical procedure for patients and physicians. However, considerable difficulty and a poorer comparability result from the variations in sequences used in the detection of this multifaceted disease. Therefore, a standardization of MRI protocols used in the detection of DIE will be a crucial step towards increased diagnostic validity and the ENZIAN score may be used as an anatomical land map and valuable communication tool between radiologists and gynecologists.

Does endometriosis affect professional life? A matched case-control study in Switzerland, Germany and Austria.

OBJECTIVES: Endometriosis is a gynaecological disease most commonly causing severe and chronic pelvic pain as well as an impaired quality of life. The aim of this study was to investigate if and how endometriosis affects choices regarding professional life as well as the quality of daily working life. DESIGN, SETTING AND PARTICIPANTS: In the context of a multicentre case-control study, we collected data from 505 women with surgically/histologically confirmed diagnosis of endometriosis and 505 matched controls. Study participants were recruited prospectively in hospitals and doctors' practices in Switzerland, Germany and Austria. Using a detailed questionnaire, the study investigated work-life and career choices of study participants. MAIN OUTCOME MEASURES: Associations between endometriosis/disease symptoms and limitations in career development as well as ability to work. RESULTS: Women with endometriosis were less often able to work in their desired profession than women from the control group (adjusted OR=1.84, 95% CI: 1.15 to 2.94, R2=0.029, p=0.001) and they had to take health-related limitations into consideration in their career decisions to a significantly higher degree than women in the control group (OR=4.79, 95% CI: 2.30 to 9.96, R2=0.063, p<0.001). Among women with endometriosis, chronic pain was significantly associated with increased sick leave (OR=3.52, 95% CI: 2.02 to 6.13, R2=0.072, p<0.001) as well as with loss of productivity at work (OR=3.08, 95% CI: 2.11 to 4.50, R2=0.087, p<0.001). CONCLUSIONS: Endometriosis is associated with impairment of professional life, in particular with regard to career choices. Further research to develop strategies to support endometriosis-affected women in realising professional opportunities is recommended. TRIAL REGISTRATION NUMBER: NCT02511626; Pre-results.

The use of home remedies and complementary health approaches in endometriosis.

RESEARCH QUESTION: Conventional treatments are often associated with adverse effects and endometriosis pain symptoms may reoccur despite treatment. Consequently, many women use complementary health approaches (CHA) and home remedies (HR) to relieve their pain. The aim of this study was to examine the frequency and the subjectively perceived efficacy of CHA/HR use by women affected by endometriosis. DESIGN: Retrospective evaluation using medical charts and a questionnaire. Women recruited in hospitals and in self-help groups were asked about the use of 'topical heat', 'repose/relaxation', 'movement/massages', 'homeopathy/phytotherapy', 'acupuncture/traditional Chinese medicine (TCM)' and 'kinesiology/physiotherapy'. RESULTS: From a total of 574 women with a confirmed diagnosis of endometriosis, 359 (62.5%) applied some form of CHA/HR. Women suffering from fatiguing disease symptoms more often selected alternative therapies (odds ratio [OR] 3.14, 95% confidence interval [CI] 1.39-7.11, P = 0.006) compared with women without these characteristics. Furthermore, women dissatisfied with healthcare provided by their treating physician, more frequently (OR 2.30, 95% CI 1.19-4.45, P = 0.013) chose the aforementioned alternative strategies. CONCLUSION: As conventional therapies may not be sufficiently effective, women's needs should be closely examined, and individual treatment options should be discussed and initiated by clinicians to provide the best comprehensive treatment possible for endometriosis.

Satisfaction with medical support in women with endometriosis.

Endometriosis affects various aspects of women's lives. We searched for predictors for patient satisfaction with medical support (PSwMS) in women with endometriosis. The study was designed as a multi-centre retrospective cohort study. We approached women with histologically confirmed endometriosis from 2010 until 2016, comparing women satisfied to women dissatisfied with medical support. We analysed data on characteristics of endometriosis, PSwMS and the influence of disease characteristics on PSwMS. Information on satisfaction with medical support was collected through a standardized questionnaire. After exclusion of 73 women because of inchoately filled in questionnaires, data from 498 women was evaluated. Altogether, it was observed that 54.6% (n = 272) of the study participants were satisfied with medical support and 45.4% (n = 226) were not. Feeling adequately informed by the time of diagnosis (p < 0.001), taking women's mental troubles seriously (p < 0.001) and supporting women in handling their pain (p < 0.001) were significantly associated with satisfaction. We found adequate information to be the most distinctive indicator for PSwMS. Further, acknowledging psychological distress and supporting women in handling their symptoms rather than to alleviate them, positively affect PSwMS. To achieve PSwMS, healthcare providers have to give adequate information on endometriosis and its management.

Fatigue - a symptom in endometriosis.

STUDY QUESTION: Is fatigue a frequent symptom of endometriosis? SUMMARY ANSWER: Fatigue is an underestimated symptom of endometriosis as it affects the majority of women with endometriosis, but it is not widely discussed in literature. WHAT IS KNOWN ALREADY: Fatigue can be a symptom of endometriosis causing major distress impacting the daily activities and quality of life of women with endometriosis. However, few studies with large sample sizes have investigated fatigue as a symptom of endometriosis. STUDY DESIGN, SIZE, DURATION: The study was designed as a multi-center matched case-control study. Recruitment took place at hospitals and private practices in Switzerland, Germany and Austria between 2010 and 2016. Data was collected from 1120 women, 560 of them with endometriosis. The women with endometriosis were matched to 560 control women in regard to age ±3 years and ethnic background. PARTICIPANTS/MATERIALS, SETTING, METHODS: Diagnosis of women with endometriosis had to be surgically and histologically confirmed. Surgical exclusion or absence of any endometriosis-identifying symptoms was required for control subjects. Materials included surgical and histological reports as well as data retrieved from a self-administered questionnaire. This study focused on the symptom fatigue in endometriosis. Relationships of variables were established by regression analysis and associations were quantified as odds ratios. MAIN RESULTS AND THE ROLE OF CHANCE: Frequent fatigue was experienced by a majority of women diagnosed with endometriosis (50.7% versus 22.4% in control women, P < 0.001). Fatigue in endometriosis was associated with insomnia (OR: 7.31, CI: 4.62-11.56, P < 0.001), depression (OR: 4.45, CI: 2.76-7.19, P < 0.001), pain (OR: 2.22, CI: 1.52-3.23, P < 0.001), and occupational stress (OR: 1.45, CI: 1.02-2.07, P = 0.037), but was independent of age, time since first diagnosis and stage of the disease. LIMITATIONS, REASONS FOR CAUTION: Women with asymptomatic endometriosis cannot be excluded in the control group which would lead to underestimation of our results. The study's design allows no evaluation of causal effects. WIDER IMPLICATIONS OF THE FINDINGS: As fatigue is experienced by numerous women with endometriosis, it needs to be addressed in the discussion of management and treatment of the disease. In addition to treating endometriosis, it would be beneficial to reduce insomnia, depression, pain and occupational stress in order to better manage fatigue. STUDY FUNDING/COMPETING INTEREST(S): There was no additional funding received for this study and no conflict of interest. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT02511626.

Does Endometriosis Affect Sexual Activity and Satisfaction of the Man Partner? A Comparison of Partners From Women Diagnosed With Endometriosis and Controls.

BACKGROUND: Endometriosis-associated pain and dyspareunia influence female sexuality, but little is known about men's experiences in affected couples. AIM: To investigate how men partners experience sexuality in partnership with women with endometriosis. METHODS: A multi-center case-control study was performed between 2010 and 2015 in Switzerland, Germany, and Austria. 236 Partners of endometriosis patients and 236 partners of age-matched control women without endometriosis with a similar ethnic background were asked to answer selected, relevant questions of the Brief Index of Sexual Functioning and the Global Sexual Functioning questionnaire, as well as some investigator-derived questions. OUTCOMES: We sought to evaluate sexual satisfaction of men partners of endometriosis patients, investigate differences in sexual activities between men partners of women with and without endometriosis, and identify options to improve partnership sexuality in couples affected by endometriosis. RESULTS: Many partners of endometriosis patients reported changes in sexuality (75%). A majority of both groups was (very) satisfied with their sexual relationship (73.8% vs 58.1%, P = .002). Nevertheless, more partners of women diagnosed with endometriosis were not satisfied (P = .002) and their sexual problems more strongly interfered with relationship happiness (P = .001) than in partners of control women. Frequencies of sexual intercourse (P < .001) and all other partnered sexual activities (oral sex, petting) were significantly higher in the control group. The wish for an increased frequency of sexual activity (P = .387) and sexual desire (P = .919) did not differ statistically between both groups. CLINICAL TRANSLATION: There is a need to evaluate qualitative factors that influence sexual satisfaction in endometriosis patients. CONCLUSIONS: This is one of the first studies to investigate male sexuality affected by endometriosis. The meticulous verification of diagnosis and disease stage according to operation reports and histology allows for a high reliability of diagnosis. Our men's response rate of almost 50% is higher compared to other studies. Recruiting men through their woman partner may have caused selection bias. The adjustment to the specific situation in endometriosis by selecting questions from the Brief Index of Sexual Functioning and Global Sexual Functioning and adding investigator-derived questions likely influenced the validity of the questionnaires. Despite the fact that both partners of endometriosis patients and of control women largely reported high sexual satisfaction, there are challenges for some couples that arise in the context of a sexual relationship when one partner has endometriosis. Challenges such as sexuality-related pain or a reduced frequency of sexual activities should be addressed by health care professionals to ameliorate any current difficulties and to prevent the development or aggravation of sexual dysfunction.
