Abstract
OBJECTIVE To evaluate rate and determinants of long-term recurrence of endometriosis in a population of young women. DESIGN Retrospective cohort study. SETTING University tertiary care referral center for women with benign gynecologic diseases. PARTICIPANTS Young women undergoing first-line conservative surgery for endometriosis were eligible for the study. Data on age at surgery, disease stage, anatomical characteristics of endometriotic lesions, and endometriosis-related symptoms were collected. After diagnosis, patients were treated according to the standard care of the center. The protocol required all women to be followed up 1 month after surgery, and every 6 months afterward, with an interview to investigate persistence of symptoms, a clinical examination, and an ultrasound pelvic assessment. RESULTS Fifty-seven women aged ≤ 21 (mean age at diagnosis ± SD: 19.0 ± 1.1 years) entered the study. During a 5-year follow-up, 32 (56%, 95% confidence interval [CI]: 43%-68%) recurrences of endometriosis were diagnosed. A second laparoscopy to treat the recurrence was performed in 11 (34%) cases and confirmed the presence of the disease in all of them. In the remaining 21 (66%) cases, the recurrence was based on the reappearance of the symptoms or clinical or sonographic findings. The recurrence rate increased constantly with time from first surgery. No association emerged between recurrence rate and endometriosis-related symptoms, site/stage of the disease, type of surgery, and post-surgical medical treatment. CONCLUSIONS The recurrence rate of endometriosis in young women appears higher than in older women. Since no determinants for recurrence have been detected among the factors examined, a profile of women at increased risk cannot be drawn.

Abstract
Purpose The symptoms of endometriosis are heterogeneous and overlap with those of other conditions, resulting in misdiagnoses and/or delayed diagnosis and treatment. The Uterine Bleeding and Pain Women's Research Study (UBP-WRS) collected data to elucidate differences in diagnoses and treatment experiences of women, and to assess the impact of endometriosis on their quality of life. Methods The UBP-WRS interviewed women aged 15 to 49 in eight countries using an online methodology. Quotas were applied for the age, region, level of education, and income of respondents. Questions assessed menstruation, diagnoses of endometriosis or other gynecological conditions (e.g., uterine fibroids), symptoms, impact on life, and perceptions of treatments. Results Of the total of 21 749 women, 2.7% reported surgically diagnosed endometriosis, 2.4% reported nonsurgically diagnosed endometriosis, 5.5% had physician-suspected endometriosis, and 6.2% reported symptoms indicative of endometriosis but no diagnosis. Prevalence of the different diagnoses was comparable between countries. Mean age at diagnosis was 28 years and estimated time-to-diagnosis was 6.1 years. Pain symptoms were generally more common and severe in women with diagnosed endometriosis than in those with suspected disease, whereas the reverse was true for their quality-of-life. Of women receiving treatment for diagnosed endometriosis, 60% were satisfied and 40% were dissatisfied with efficacy. However, 29% of women with diagnosed endometriosis were not receiving any treatment. Conclusions Approximately 17% of women in the UBP-WRS reported diagnosed, suspected or symptoms of endometriosis; this is comparable to previously published studies. The UBP-WRS – among the largest surveys of its kind – may help to improve understanding of this enigmatic disease and guide therapeutic practices.

Abstract
Endometriosis is a chronic disease primarily affecting women of childbearing age, in which endometriotic lesions form outside the uterus, typically leading to painful symptoms, fatigue, and infertility. The symptoms of endometriosis may cause significant impairment in quality of life and represent a substantial economic burden to patients, families, and society. There is no cure for endometriosis; management consists of alleviating pain and other symptoms, reducing endometriotic lesions, and improving quality of life. Recurrence after surgical intervention is common, while the clinical evidence to support the efficacy and safety of many medications currently used in endometriosis is limited. Dienogest is an oral progestin that has been investigated extensively in the treatment of endometriosis in two clinical programs performed in Europe and Japan, including dose-ranging, placebo-controlled, active comparator-controlled, and long-term (up to 65 weeks) studies. These studies demonstrated that dienogest 2 mg daily effectively alleviates the painful symptoms of endometriosis, reduces endometriotic lesions, and improves indices of quality of life. Dienogest showed a favorable safety and tolerability profile in these studies, with predictable adverse effects, high rates of patient compliance, and low withdrawal rates. This review article describes the clinical trial evidence that characterizes the efficacy and safety of dienogest in endometriosis, including two studies characterizing dienogest in long-term use. The relevance of these findings to the management of endometriosis in clinical practice is discussed.

Abstract
Purpose To investigate the efficacy and safety of dienogest as a long-term treatment in endometriosis, with follow-up after treatment discontinuation. The study included women with endometriosis, who had previously completed a 12-week, placebo-controlled study of dienogest, who participated in an open-label extension study for up to 53 weeks. Thereafter, a patient subgroup was evaluated in a 24-week follow-up after treatment discontinuation. Methods A multicenter study performed in Germany, Italy and Ukraine. Women with endometriosis were enrolled at completion of the placebo-controlled study (n = 168). All women received dienogest (2 mg once daily, orally) and changes in pelvic pain (on a visual analog scale), bleeding pattern, adverse events and laboratory parameters were evaluated during and after treatment. Results The completion rate among women who entered the open-label extension study was 90.5% (n = 152). A significant decrease in pelvic pain was shown during continued dienogest treatment (P < 0.001). The mean frequency and intensity of bleeding progressively decreased. Adverse events, rated generally mild or moderate, led to withdrawal in four patients (2.4%). No clinically relevant changes in laboratory parameters were observed. During treatment-free follow-up (n = 34), the reduction in pelvic pain persisted, while bleeding frequency and intensity returned to normal patterns. Conclusions Long-term dienogest showed a favorable efficacy and safety profile, with progressive decreases in pain and bleeding irregularities during continued treatment; the decrease of pelvic pain persisted for at least 24 weeks after treatment cessation.

Abstract
Endometriosis is defined as the presence of endometrial glands and stroma outside the uterine cavity. Although the exact pathophysiology is unclear, endometriosis is a well-known cause of pelvic pain and infertility in reproductive-aged women. Endometriosis can have extrapelvic manifestations relevant for colorectal surgeons to appreciate, such as cyclic constipation, diarrhea, hematochezia, and dyschezia. The treatment of endometriosis involves a combination of medical and surgical interventions where close collaboration between the gynecologist and colorectal surgeon can help achieve prolonged periods of symptom remission.

Abstract
OBJECTIVE Cumulative evidence supports the view that ovarian endometriomas originate from ovulatory events and that the ovarian reserve is reduced following surgery. On these bases, we have hypothesized that the risk of recurrence may be related to the residual ovarian reserve of the operated ovary. STUDY DESIGN We retrospectively selected 45 women scheduled for in vitro fertilization who previously underwent surgical excision of monolateral endometriomas and compared ovarian responsiveness in those who did (n = 24) and did not (n = 21) have a recurrent endometrioma. RESULTS In the intact ovaries, the mean ± SD number of codominant follicles in women with and without recurrences was 3.5 ± 1.7 and 3.7 ± 2.2, respectively (P = NS). In the affected ovaries, the mean ± SD number of follicles in gonads with and without recurrences was 2.5 ± 2.3 and 1.1 ± 1.5, respectively (P < .05). CONCLUSION Ovarian responsiveness is higher in gonads that developed recurrent endometriomas.

Abstract
Endometriosis, the growth of endometrial tissue outside the uterine cavity, is a common gynecological disorder affecting 10% to 15% of women in their reproductive years. Retrograde menstrual shedding containing endometrial stem/progenitor cells has been postulated to be involved in its pathogenesis. In this study, we identified putative endometriotic stem/progenitor cells by their colony-forming potential, self-renewal capacity, and multipotency. Purified epithelial and stromal cells isolated from ovarian endometriotic cysts formed large and small colony-forming units (CFUs) in clonogenic assay. The colony-forming activity of epithelial and stromal cells was found to differ greatly between autologous endometrium and ovarian endometrioma samples. The large CFUs could propagate more than the small CFUs. The endometriotic epithelial small CFUs expressed epithelial markers (epithelial cell adhesion molecule, cytokeratin, and α6 integrin); only occasional large CFUs expressed α6 integrin. Aside from the expression of fibroblast markers, stromal CFUs also expressed three somatic stem cell markers: sal-like 4, CD133, and Musashi-1. Endometriotic stromal cells derived from large CFUs could differentiate into four mesenchymal lineages when cultured in the respective inducing-media, as determined by histochemical staining and RT-PCR of lineage specific markers. These findings demonstrate that ovarian endometrioma contains a subset of cells displaying somatic stem cell properties.

Abstract
China was the first country in the world that approved mifepristone (RU-486) for abortion. A total of 6 years after the report published in the Western world indicated that mifepristone may also be effective in treating endometriosis, the first paper on the same topic was published in China in 1997. Since then, over 160 studies on this topic have been published in China. We retrieved 104 papers on clinical trials and trial-like studies conducted in China evaluating the use of mifepristone to treat endometriosis that were published in the last 11 years. We found that the quality of these studies is well below an acceptable level, making it difficult to judge whether mifepristone is truly efficacious. There are intriguing signs that these studies, as a whole, have serious anomalies. The areas that are glaringly deficient are informed consent, choice of outcome measures, the evaluation of outcome measures, data analysis and randomization. The uniformly low quality is disquieting, given the large quantity of studies, the enormous amount of resource and energy put into these studies and, above all, the weighty issue of treatment efficacy that concerns each and every patient with endometriosis. Equally disquieting are the low-quality repetition, the absence of a critical, systematic review on the subject, the lack of suggestions for multicenter clinical trials and the seemingly unnecessary duplication of clinical trials without due informed consent. In view of this, it may be time to institute changes in attitude and practice, and to change education and training programs in the methodology of clinical trials in obstetrics and gynecology research in China.

Abstract
BACKGROUND Endometriosis is estimated to affect 1 in 10 women during the reproductive years. There is often delay in making the diagnosis, mainly due to the non-specific nature of the associated symptoms and the need to verify the disease surgically. A biomarker that is simple to measure could help clinicians to diagnose (or at least exclude) endometriosis; it might also allow the effects of treatment to be monitored. If effective, such a marker or panel of markers could prevent unnecessary diagnostic procedures and/or recognize treatment failure at an early stage. METHODS We used QUADAS (Quality Assessment of Diagnostic Accuracy Studies) criteria to perform a systematic review of the literature over the last 25 years to assess critically the clinical value of all proposed biomarkers for endometriosis in serum, plasma and urine. RESULTS We identified over 100 putative biomarkers in publications that met the selection criteria. We were unable to identify a single biomarker or panel of biomarkers that have unequivocally been shown to be clinically useful. CONCLUSIONS Peripheral biomarkers show promise as diagnostic aids, but further research is necessary before they can be recommended in routine clinical care. Panels of markers may allow increased sensitivity and specificity of any diagnostic test.

Abstract
OBJECTIVE We report the first randomized trial of laparoscopically assisted versus open colorectal resection for endometriosis focusing on perioperative complications, improvement in symptoms, quality of life, and fertility. SUMMARY OF BACKGROUND DATA Bowel endometriosis is one of the most severe forms of endometriosis. Although laparoscopically assisted surgery is a validated technique for colorectal cancer, there are serious concerns about its appropriateness for endometriosis in young women wishing to conceive because it is almost invariably a traumatic procedure. METHODS We conducted a noninferiority trial and randomly assigned 52 patients with colorectal endometriosis to undergo laparoscopically assisted or open colorectal resection. The median follow-up was 19 months. The primary end point was improvement in dyschesia. RESULTS Overall, a significant improvement in digestive symptoms (dyschesia P < 0.0001, diarrhea P < 0.01, and bowel pain and cramping P < 0.0001), gynecologic symptoms (dysmenorrhea P < 0.0001 and dyspareunia P < 0.0001), and general symptoms (back pain P = 0.001 and asthenia P = 0.0001) was observed. No difference in the symptom delta values and quality of life was noted between the groups. Median blood loss was lower in the laparoscopic group (P < 0.05). Total number of complications was higher in the open surgery group (P = 0.04), especially grade 3 (P = 0.03). Pregnancy rate was higher in the laparoscopic group (P = 0.006), and the cumulative pregnancy rate was 60%. CONCLUSION Our findings support that laparoscopy is a safe option for women requiring colorectal resection for endometriosis. Moreover, laparoscopy offers a higher pregnancy rate than open surgery with similar improvements in symptoms and in quality of life.

Abstract
Endometriosis is the primary cause of infertility in women, with a prevalence rate ranging from 5% to 10%. Women with endometriosis suffer from symptoms such as chronic pelvic pain, dysmenorrhea and dyspareunia, which significantly reduce the quality of life. Endometriosis is a polygenic disease with a complex, multifactorial etiology. The mechanism responsible for the initiation and development of this disease remains largely unknown. Prostaglandin E2 (PGE2), a versatile eicosanoid that exerts numerous physiological and pathological functions, has been implicated to play critical roles in the development of endometriosis. A growing body of evidence demonstrates that PGE2 regulates many pathophysiological processes including cell proliferation, antiapoptosis, immune suppression and angiogenesis during the development of endometriosis. This review focuses on recent advances in cellular and molecular mechanisms triggered by PGE2 that contribute to the pathological processes of endometriosis.

Abstract
Prevention of the recurrence of post-operative endometriosis is crucial for future fertility. The incidence of disease relapse can be influenced by major demographic changes and by the use of long-term adjuvant medical treatment. Decrease in age at menarche, number of pregnancies and duration of breastfeeding and increase in age at first birth all lead to an increase in the overall number of ovulations and menstruations a woman has within a reproductive lifespan. These changes impact during the decade at highest risk for endometriosis, i.e. between 25 and 35 years of age, and may substantially expand the hiatus between first-line surgical treatment and conception attempt. Several lines of evidence suggest that ovulation inhibition reduces the risk of endometriosis recurrence. After pooling the results of a cohort and a randomized controlled trial on long-term post-operative oral contraceptive use, a recurrent endometrioma developed in 26/250 regular users (10%; 95% CI 7-15%) compared with 46/115 never users (40%; 95% CI 31-50%), with a common OR of 0.16 (95% CI 0.04-0.65). After first-line surgery for endometriosis, women should be invited to seek conception as soon as possible. Alternatively, oral contraceptive use until pregnancy is desired should be considered.

Abstract
BACKGROUND Dienogest is a selective progestin that has been investigated in a clinical trial programme for the treatment of endometriosis. The current non-inferiority trial compared the efficacy and safety of dienogest against leuprolide acetate (LA) for treating the pain associated with endometriosis. METHODS Patients with confirmed endometriosis were randomized to treatment with dienogest (2 mg/day, orally) or LA (3.75 mg, depot i.m. injection, every 4 weeks) for 24 weeks. The primary efficacy variable was absolute change in pelvic pain from baseline to end of treatment, assessed by visual analogue scale (VAS). Safety variables included adverse event profile, laboratory parameters, bone mineral density (BMD), bone markers and bleeding patterns. RESULTS A total of 252 women were randomized to treatment with dienogest (n = 124) or LA (n = 128); 87.9 and 93.8% of the respective groups completed the trial. Absolute reductions in VAS score from baseline to Week 24 were 47.5 mm with dienogest and 46.0 mm with LA, demonstrating the equivalence of dienogest relative to LA. Hypoestrogenic effects (e.g. hot flushes) were reported less frequently in the dienogest group. As expected, bleeding episodes were suppressed less with dienogest than with LA. Changes in mean lumbar BMD between screening and final visit were +0.25% with dienogest and -4.04% with LA subgroups (P = 0.0003). Markers of bone resorption increased with LA but not dienogest. CONCLUSIONS Dienogest 2 mg/day orally demonstrated equivalent efficacy to depot LA at standard dose in relieving the pain associated with endometriosis, although offering advantages in safety and tolerability.

Abstract
In response to the pressing need for more efficacious and safer therapeutics for endometriosis, there have been numerous reports in the last decade of positive results from animal and in vitro studies of various compounds as potential therapeutics for endometriosis. A handful of these have undergone phase II/III clinical trials. Since the announcement of the International Committee of Medical Journal Editors that mandated registration as a prerequisite for publication, 57 endometriosis-related clinical trials have been registered at ClinicalTrials.gov, an Internet-based public depository for information on drug studies. Among them, 25 are listed as completed, and 2 as suspended. There are 15 completed phase II/III trials, which evaluated the efficacy of various promising compounds. Yet only three of the 15 trials (20%) have published their results. The remaining 12 (80%) studies so far have not published their findings. We argue that this apparent lack of transparency will actually not benefit the trial sponsors or the public, and will ultimately prove detrimental to research efforts attempting to develop more efficacious and safer therapeutics for endometriosis. Thus we call for more transparency of clinical trials on endometriosis.

Abstract
The regressive potential of the borderline patient has been recognized ever since the term was first introduced by Adolph Stern in 1938. He believed these patients were "too ill for classical psychoanalysis," and indeed almost all who have written on this subject have supported Stern's view, recognizing the severe regressive potential of a borderline patient in unmodified psychoanalysis. Taking medication is not generally considered to be a particularly regressive experience. It should be remembered, however, that for many patients and especially for patients with borderline personality disorder, medication can be both an overvalued hope and a terrifying assault. Thus, although the pharmacologic action of the medication may help to integrate the patient's ego functioning, the very taking of the medication may at the same time initiate subtle and unanticipated regressive drives. Two forces are then set in motion with potentially different effects. In a treatment where the same physician is prescribing medication and doing psychotherapy, the common pathway of these forces is transference. Thus, pharmacologic action may modify transference. And more importantly, because it is less easily recognized, transference issues may affect the patient's subjective experience of the action of the medication. For this reason, it is particularly important that not only diagnostic issues but also transference issues be understood before medication is prescribed.(ABSTRACT TRUNCATED AT 250 WORDS)
