Abstract
OBJECTIVE To assess the reporting quality of published RCT abstracts regarding patients with endometriosis pelvic pain and investigate the prevalence and characteristics of spin in these abstracts. METHODS PubMed and Scopus were searched for RCT abstracts addressing endometriosis pelvic pain published from January 1st, 2010 to December 1st, 2023.The reporting quality of RCT abstracts was assessed using the CONSORT statement for abstracts. Additionally, spin was evaluated in the results and conclusions section of the abstracts, defined as the misleading reporting of study findings to emphasize the perceived benefits of an intervention or to confound readers from statistically non-significant results. Assessing factors affecting the reporting quality and spin existence, linear and logistic regression was used, respectively. RESULTS A total of 47 RCT abstracts were included. Out of 16 checklist items, only three items including objective, intervention and conclusions were sufficiently reported in the most abstracts (more than 95%), and none of the abstracts presented precise data as required by the CONSORT-A guidelines. In the reporting quality of material and method section, trial design, type of randomization, the generation of random allocation sequences, the allocation concealment and blinding were most items identified that were suboptimal. The total score for the quality varied between 5 and 15 (mean: 9.59, SD: 3.03, median: 9, IQR: 5). Word count (beta = 0.015, p-value = 0.005) and publishing in open-accessed journals (beta = 2.023, p-value = 0.023) were the significant factors that affecting the reporting quality. Evaluating spin within each included paper, we found that 18 (51.43%) papers had statistically non-significant results. From these studies, 12 (66.66%) had spin in both results and conclusion sections. Furthermore, the spin intensity increased during 2010-2023 and 38.29% of abstracts had spin in both results and conclusion sections. CONCLUSION Overall poor adherence to CONSORT-A was observed, with spin detected in several RCTs featuring non-significant primary endpoints in obstetrics and gynecology literature.

Abstract
Except when surgery is the only option because of organ damage, the presence of suspicious lesions, or the desire to conceive, women with endometriosis-associated pain often face a choice between medical and surgical treatment. In theory, the description of the potential benefits and potential harms of the two alternatives should be standardized, unbiased, and based on strong evidence, enabling the patient to make an informed decision. However, doctor's opinion, intellectual competing interests, local availability of specific services and (mis)information obtained from social media, and online support groups can influence the type of advice given and affect patients' choices. This is compounded by the paucity of robust data from randomized controlled trials, and the anxiety of distressed women who are eager to do anything to alleviate their disabling symptoms. Vulnerable patients are more likely to accept the suggestions of their healthcare provider, which can lead to unbalanced and physician-centred decisions, whether in favour of either medical or surgical treatment. In general, treatments should be symptom-orientated rather than lesion-orientated. Medical and surgical modalities appear to be similarly effective in reducing pain symptoms, with medications generally more successful for severe dysmenorrhoea and surgery more successful for severe deep dyspareunia caused by fibrotic lesions infiltrating the posterior compartment. Oestrogen-progestogen combinations and progestogen monotherapies are generally safe and well tolerated, provided there are no major contraindications. About three-quarters of patients with superficial peritoneal and ovarian endometriosis and two-thirds of those with infiltrating fibrotic lesions are ultimately satisfied with their medical treatment although the remainder may experience side effects, which may result in non-compliance. Surgery for superficial and ovarian endometriosis is usually safe. When fibrotic infiltrating lesions are present, morbidity varies greatly depending on the skill of the individual surgeon, the need for advanced procedures, such as bowel resection and ureteral reimplantation, and the availability of expert colorectal surgeons and urologists working together in a multidisciplinary approach. The generalizability of published results is adequate for medical treatment but very limited for surgery. Moreover, on the one hand, hormonal drugs induce disease remission but do not cure endometriosis, and symptom relapse is expected when the drugs are discontinued; on the other hand, the same drugs should be used after lesion excision, which also does not cure endometriosis, to prevent an overall cumulative symptom and lesion recurrence rate of 10% per postoperative year. Therefore, the real choice may not be between medical treatment and surgery, but between medical treatment alone and surgery plus postoperative medical treatment. The experience of pain in women with endometriosis is a complex phenomenon that is not exclusively based on nociception, although the role of peripheral and central sensitization is not fully understood. In addition, trauma, and especially sexual trauma, and pelvic floor disorders can cause or contribute to symptoms in many individuals with chronic pelvic pain, and healthcare providers should never take for granted that diagnosed or suspected endometriosis is always the real, or the sole, origin of the referred complaints. Alternative treatment modalities are available that can help address most of the additional causes contributing to symptoms. Pain management in women with endometriosis may be more than a choice between medical and surgical treatment and may require comprehensive care by a multidisciplinary team including psychologists, sexologists, physiotherapists, dieticians, and pain therapists. An often missing factor in successful treatment is empathy on the part of healthcare providers. Being heard and understood, receiving simple and clear explanations and honest communication about uncertainties, being invited to share medical decisions after receiving detailed and impartial information, and being reassured that a team member will be available should a major problem arise, can greatly increase trust in doctors and transform a lonely and frustrating experience into a guided and supported journey, during which coping with this chronic disease is gradually learned and eventually accepted. Within this broader scenario, patient-centred medicine is the priority, and whether or when to resort to surgery or choose the medical option remains the prerogative of each individual woman.

Abstract
OBJECTIVE Dienogest (DNG), a fourth-generation progestin, reduces pain associated with endometriosis and uterine adenomyosis; however, it is associated with irregular uterine bleeding that can cause anemia and poor quality of life. We investigated risk factors for heavy bleeding following DNG administration. MATERIALS AND METHODS We retrospectively investigated patients who received DNG for risk factors of heavy uterine bleeding, including clinical diagnosis, use of pretreatment gonadotropin-releasing hormone agonist, smoking, cancer antigen 125, and blood hormone levels. We additionally assessed the uterine area in patients with uterine adenomyosis, the major axis of the uterine body, the major axis of myometrial thickness, the site of tumor development, and the site of myoma development in patients with uterine fibroids. RESULTS Eighty Japanese patients were administered DNG. The median age was 41 (range: 24-51) years. The odds ratio (OR) for moderate-to-severe bleeding according to clinical diagnosis were 0.33 (P = 0.011) for endometrioma and 9.00 (P = 0.049) for uterine adenomyosis. Receiver operating characteristic curve analysis of the uterine area associated with uterine adenomyosis showed an area under the curve (AUC) of 0.909 between those with major and minor bleeding, with an optimal cut-off value of 7388.2 mm2. The uterine body major axis had an AUC of 0.946, with an optimal cut-off value of 78.3 mm. The major axis of myometrial thickness had an AUC of 0.855, with an optimal cut-off value of 46.8 mm. CONCLUSION Patients with endometrioma treated with DNG were less likely to experience heavy uterine bleeding. Uterine bleeding in patients with uterine adenomyosis and adenomyosis associated with uterine fibroids should be closely monitored while administering DNG.

Abstract
The French National College of Obstetricians and Gynecologists (CNGOF) published guidelines for managing endometriosis-associated pain in 2018. Given the development of new pharmacological therapies and a review that was published in 2021, most national and international guidelines now suggest a new therapeutic approach. In addition, a novel validated screening method based on patient questionnaires and analysis of 109-miRNA saliva signatures, which combines biomarkers and artificial intelligence, opens up new avenues for overcoming diagnostic challenges in patients with pelvic pain and for avoiding laparoscopic surgery when sonography and MRI are not conclusive. Dienogest (DNG) 2 mg has been a reimbursable healthcare expense in France since 2020, and, according to recent studies, it is at least as effective as combined hormonal contraception (CHC) and can be used as an alternative to CHC for first-line treatment of endometriosis-associated pain. Since 2018, the literature concerning the use of DNG has grown considerably, and the French guidelines should be modified accordingly. The levonorgestrel intrauterine system (LNG IUS) and other available progestins per os, including DNG, or the subcutaneous implant, can be offered as first-line therapy, gonadotropin-releasing hormone (GnRH) agonists with add-back therapy (ABT) as second-line therapy. Oral GnRH antagonists are promising new medical treatments for women with endometriosis-associated pain. They competitively bind to GnRH receptors in the anterior pituitary, preventing native GnRH from binding to GnRH receptors and from stimulating the secretion of luteinizing hormone and follicle-stimulating hormone. Consequently, estradiol and progesterone production is reduced. Oral GnRH antagonists will soon be on the market in France. Given their mode of action, their efficacy is comparable to that of GnRH agonists, with the advantage of oral administration and rapid action with no flare-up effect. Combination therapy with ABT is likely to allow long-term treatment with minimal impact on bone mass. GnRH antagonists with ABT may thus be offered as second-line treatment as an alternative to GnRH agonists with ABT. This article presents an update on the management of endometriosis-associated pain in women who do not have an immediate desire for pregnancy.

Abstract
This work provides consensus guidance regarding clinical diagnosis and early medical management of endometriosis within Asia. Clinicians with expertise in endometriosis critically evaluated available evidence on clinical diagnosis and early medical management and their applicability to current clinical practices. Clinical diagnosis should focus on symptom recognition, which can be presumed to be endometriosis without laparoscopic confirmation. Transvaginal sonography can be appropriate for diagnosing pelvic endometriosis in select patients. For early empiric treatment, management of women with clinical presentation suggestive of endometriosis should be individualized and consider presentation and therapeutic need. Medical treatment is recommended to reduce endometriosis-associated pelvic pain for patients with no immediate pregnancy desires. Hormonal treatment can be considered for pelvic pain with a clinical endometriosis diagnosis; progestins are a first-line management option for early medical treatment, with oral progestin-based therapies generally a better option compared with combined oral contraceptives because of their safety profile. Dienogest can be used long-term if needed and a larger evidence base supports dienogest use compared with gonadotropin-releasing hormone agonists (GnRHa) as first-line medical therapy. GnRHa may be considered for first-line therapy in some specific situations or as short-term therapy before dienogest and non-steroidal anti-inflammatory drugs as add-on therapy for endometriosis-associated pelvic pain.

Abstract
Objectives: To evaluate the side effects and causes of discontinuation of either combined oral contraceptives or dienogest (DNG) used to prevent recurrence in patients with surgically confirmed endometriosis.Methods: We retrospectively analyzed the medical records of 213 women with endometriosis who had been treated with combined oral contraceptives (ethinyl estradiol 0.02 mg/drospirenone 3 mg [EE/DRSP]) or DNG 2 mg for 12 months or more. The side effects reported by the patients, laboratory parameters, causes of discontinuation of medication, and recurrence rates were evaluated one, two, three, four, and five years after starting medication (Y1, Y2, Y3, Y4, and Y5).Results: EE/DRSP were administered to 59 patients, while DNG was administered to 154 patients. The mean durations of postoperative use of EE/DRSP and DNG were 44.5 ± 22.6 months and 23.6 ± 13.5 months, respectively. The prevalence of side effects was 27.1%, 19.0%, 10.0%, 10.5%, and 7.4% in the EE/DRSP group and 29.2%, 15.7%, 14.0%, 23.1%, and 0.0% in the DNG group at Y1, Y2, Y3, Y4, and Y5, respectively. The discontinuation rates were 1.7%, 1.7%, 4.0%, 0.0%, and 7.4% at Y1, Y2, Y3, Y4, and Y5, respectively, in the EE/DRSP group and 10.4%, 3.3%, 4.0%, 3.8%, and 0.0% at the same times in the DNG group. The recurrence rates were less than 4% in both the groups.Conclusions: The side effects of commonly prescribed postoperative hormone treatments were relatively mild, and the occurrence of side effects decreased with continuous administration. Further, the long-term use of postoperative hormone treatments is likely to prevent recurrence of endometriosis after surgery.

Abstract
OBJECTIVE To evaluate the efficacy and safety of 40-mg relugolix (REL) compared with those of leuprorelin (LEU) in women with endometriosis-associated pain. DESIGN Phase 3, multicenter, randomized, double-blind, double-dummy, active-controlled study in Japanese patients. SETTING Hospitals and clinics. PATIENT(S) Women aged ≥20 years with regular menstrual cycles (25-38 days) experiencing endometriosis or ovarian endometrioma and reporting pelvic pain. INTERVENTION(S) In the REL group, 40 mg of REL was orally administered once a day for 24 weeks. In the LEU group, 3.75 or 1.88 mg of LEU was subcutaneously injected every 4 weeks for 24 weeks. MAIN OUTCOME MEASURE(S) The primary endpoint was the change in the maximum visual analog scale score for pelvic pain from baseline until 28 days before the end of treatment. RESULT(S) Changes in the maximum visual analog scale score were -52.6 ± 1.3 for REL and -57.5 ± 1.4 for LEU. Ovarian endometrioma decreased by 12.26 ± 17.52 cm3 for REL and 14.10 ± 18.81 cm3 for LEU. Drug-related treatment emergent adverse events with an incidence of >10% for both groups were hot flush, metrorrhagia, headache, and genital hemorrhage. Discontinuations from treatment emergent adverse events were 2.9% for REL and 4.3% for LEU. CONCLUSION(S) Relugolix was noninferior to LEU for treating endometriosis-associated pelvic pain. Safety profiles of both medications were comparable, although menses returned earlier in patients taking REL, a huge benefit for women who plan to conceive after treatment. CLINICAL TRIAL REGISTRATION NUMBER ClinicalTrials.gov: NCT03931915.

Abstract
We present a case of hemorrhagic shock occurred during dienogest therapy for uterine adenomyosis which necessitated an emergency hysterectomy. The patient was a 45-year-old woman with adenomyosis. Magnetic resonance imaging showed type I adenomyosis measuring 10 cm. She had a history of intimal thrombectomy of pulmonary embolism and had been receiving warfarin and aspirin until the onset of the hemorrhagic shock. Following 6-month of gonadotropin-releasing hormone analogue, dienogest was commenced. Nine months after switching to dienogest, the patient experienced a persistent abnormal uterine bleeding for 2 weeks, eventually causing a massive bleeding and was transferred to our emergency room. A diagnosis of hemorrhagic shock with a severe anemia (hemoglobin 3.6 g/dL) was made. Despite blood transfusion and warfarin antagonization, continuous bleeding ≥150 g/h was not controlled. Emergent hysterectomy was opted and enabled hemostasis. Although the number of patients with adenomyosis who can avoid surgery by dienogest is increasing, care must be taken during dienogest therapy, especially in patients with anticoagulants and after gonadotropin-releasing hormone analogue treatment. To prevent such a critical event, careful management including patient education should be carried out.

Abstract
INTRODUCTION Progestins are commonly prescribed first-line drugs for endometriosis. High rates of non-response and intolerance to these drugs have been previously reported. However, no study to date has investigated the characteristics and comorbidities of patients taking progestins in relation to treatment outcomes, so identifying which patients will respond to or tolerate the treatment is currently impossible. The purpose of this study, therefore, was to identify risk factors for non-response and discontinuation of Dienogest (DNG) in women with endometriosis. MATERIAL AND METHODS This is a retrospective cohort study including women currently taking, or newly prescribed, DNG for endometriosis-associated pain presenting in the Endometriosis Clinic of the University Hospital of Bern between January 2017 and May 2018. Women with initiation of treatment directly after surgery for endometriosis were excluded. For all participants the symptoms and comorbidities were documented. Effectiveness, tolerability and discontinuation of DNG were the primary end points. Univariate and multivariate binary logistic regression models were carried out to identify risk factors for non-response, intolerance and discontinuation of DNG. RESULTS A sufficient or excellent treatment response was reported by 85/125 (68%) participants. Genital bleeding during the DNG treatment was negatively (OR 0.185, 95% CI 0.056-0.610, P = .006) and rASRM endometriosis stages III and IV were positively (OR 3.876, 95% CI 1.202-12.498, P = .023) correlated with the DNG response. When accounting for exclusively pretreatment factors, primary dysmenorrhea (OR 0.236, 95% CI 0.090-0.615, P = .003) and suspicion of adenomyosis (OR 0.347, 95% CI 0.135-0.894, P = .028) were inversely correlated with DNG response, and the latter was also correlated with treatment discontinuation (OR 3.189, 95% CI 1.247-8.153, P = .015). CONCLUSIONS Genital bleeding during the DNG treatment and low rASRM stages are independent risk factors for DNG non-response. Before treatment initiation, primary dysmenorrhea and suspicion of adenomyosis correlate with DNG non-response. The results could assist the clinician first to provide detailed information to women before treatment initiation, second to identify and possibly modify in-therapy factors correlated to treatment effectiveness and lastly to switch treatment on time if needed.

Abstract
Objective To evaluate the effectiveness of triptorelin for the treatment of adenomyosis, the benign invasion of endometrial tissue into the myometrium, as a fertility‐preserving alternative to the gold standard hysterectomy. Methods In this multicenter, open‐label, observational study in Russia, performed from November 3, 2011, to August 24, 2015, we assessed the efficacy and safety of triptorelin 3.75 mg administered intramuscularly every 28 days in Russian women who were gonadotropin‐releasing hormone agonist treatment‐naïve, aged 25–40 years, and had a diagnosis of endometriosis or adenomyosis with heavy menstrual bleeding. We performed a medical record review, interviews to assess symptom severity, and pelvic assessments including transvaginal ultrasound. Data were obtained at first injection of triptorelin (visit 1), on the day of last injection (visit 2), 6 months after last injection (visit 3), and 9 months after last injection (visit 4). Significance was assessed by Wilcoxon signed rank test. Results A total of 465 women were included. There was a significant improvement from baseline in severity of heavy menstrual bleeding in 390/463 (84.2%) of women 6 months after last injection (P<0.0001). Severity of dysmenorrhea, abnormal uterine bleeding, and pelvic pain was decreased at visit 3 compared with baseline (P<0.0001). Endometriosis symptoms stopped in 253/262 (96.6%) of women at visit 2 and in 243/263 (92.4%) of women at visit 3. Pregnancy was reported in 116/465 (24.9%) women within 9 months following the end of treatment. Conclusion Triptorelin has a favorable safety profile, is highly efficacious in treating clinical symptoms of adenomyosis, and improves reproductive function. ClinicalTrials.gov registration number: A‐38‐52014‐191, registered October 2011.

Abstract
Endometriosis infiltrating the bowel can be treated medically in accurately selected women not seeking conception and without overt obstructive symptomatology. When the rectosigmoid junction is involved, the probabilities of intestinal symptoms relief, undergoing surgery after treatment failure, and developing bowel obstruction during hormonal treatment are around 70%, 10%, and 1-2%, respectively. When the lesion infiltrates exclusively the mid-rectum, thus in cases of true rectovaginal endometriosis, the probabilities of intestinal symptoms relief and undergoing surgery are about 80% and 3%, respectively. Endometriotic obstructions of the rectal ampulla have not been reported. A rectosigmoidoscopy or colonoscopy should be performed systematically before starting medical therapies, also to rule out malignant tumours arising from the intestinal mucosa. Progestogens are safe, generally effective, well-tolerated, inexpensive, and should be considered as first-line medications for bowel endometriosis. Independently of symptom relief, intestinal lesions should be checked periodically to exclude nodule progression during hormonal treatment.

Abstract
This study elucidated the degree of adenomyosis recurrence following gonadotropin-releasing hormone agonist (GnRHa) discontinuation and dienogest efficiency for recurrent adenomyosis. This retrospective cohort study included 30 patients, divided into a group of patients whose progress was observed without providing additional therapy following GnRHa administration for six months (Group G) and a group of patients administered dienogest for six months following six months of GnRHa administration (Group D). Menorrhagia, dysmenorrhea, chronic pelvic pain, abdominal fullness, and uterine volume were recorded prior to treatment, six months after the start of therapy (6 M), and 12 months after the start of therapy (12 M). In Group G (n = 15), although all subjective symptoms disappeared at 6 M, nearly all symptoms recurred at 12 M. Uterine volume significantly decreased from 341.0 cm3 to 156.0 cm3 at 6 M (p = .001) and significantly increased again to 282.3 cm3 at 12 M (p = .003). In Group D (n = 15), all subjective symptoms disappeared at 6 M, and only abdominal fullness returned in a significant number of patients (5 of 5; p = .021) at 12 M. Uterine volume decreased significantly at 6 M (p = .003) and significantly increased again from 162.5 cm3 to 205.6 cm3 at 12 M (p = .006). Subjective symptoms, except for abdominal fullness, did not recur when dienogest was administered after GnRHa.

Abstract
Objective: Endometriosis affects up to 10% of women of reproductive age, and the main goal of treatment is to relieve symptoms. Progestins have been the mainstay of endometriosis suppression, of which dienogest has become an important option in many parts of the world. This is an expert literature review, with recommendations on the use of dienogest in the context of various clinical considerations when treating endometriosis.Methods: A search of PubMed was conducted for papers published between 2007 and 2019 on the use of dienogest in endometriosis. Experts reviewed these and included those they considered most relevant in clinical practice, according to their own clinical experience.Results: Evidence regarding the long-term use (>15 months) of dienogest for the management of endometriosis is presented, with experts concluding that the efficacy of dienogest should be assessed primarily on its impact on pain and quality of life. Fertility preservation, the option to avoid or delay surgery, and managing bleeding irregularities that can occur with this treatment are also considered. Counseling women on potential bleeding risks before starting treatment may be helpful, and evidence suggests that few women discontinue treatment for this reason, with the benefits of treatment outweighing any impact of bleeding irregularities.Conclusions: Overall, the evidence demonstrates that dienogest offers an effective and tolerable alternative or adjunct to surgery and provides many advantages over combined hormonal contraceptives for the treatment of endometriosis. It is important that treatment guidelines are followed and care is tailored to the woman's individual needs and desires.

Abstract
Herlyn-Werner-Wunderlich syndrome (HWWs) is a rare congenital malformation that involves uterus dideslphys, obstructed hemivagina and ipsilateral renal agenesis. The obstructed vagina affects menstrual flow and causes related clinical features after menarche. Pelvic endometriosis is one of the common complications of HWWs. Resection of the vaginal septum can release the obstruction and result in good outcomes. However, in the case of cervical atresia, a rare variant of HWWs, ipsilateral hysterectomy is recommended because it is difficult to canalize cervical atresia surgically. Here we present a case of HWWs with cervical atresia complicated with pelvic endometriosis. She was treated with laparoscopic ovarian cystectomy followed by hormonal therapy. Six months after surgery, there is no evidence of recurrence of endometrioma.

Abstract
We aimed to examine how leuprorelin has been studied for the treatment of women with endometriosis in Asia. We conducted a literature search of PubMed, the Cochrane Library and ClinicalTrials.gov. This review includes randomised trials of women with endometriosis treated with leuprorelin in Asia. Phase I-IV clinical trials published between January 1 2000 and December 31 2016 and written in English were included. Four studies were identified, showing that leuprorelin significantly improves pain and quality of life. The oestrone and oestradiol levels are decreased by leuprorelin but can be increased using an 'add-back' therapy with conjugated equine oestrogen and methoxyprogesterone. Menopause is more common in women treated with leuprorelin. The bone mineral density is reduced in women treated with leuprorelin. There are limited studies investigating the use of leuprorelin for the treatment of endometriosis in Asian populations. However, the research that has been conducted supports the use of leuprorelin in an Asian population.

Abstract
Objective To compare the efficacy and safety of dienogest (DNG) with depot leuprolide acetate (LA) in patients with recurrent pelvic pain following laparoscopic surgery for endometriosis. Design Prospective randomized trial. Setting Zagazig University hospitals, Egypt. Patients Two hundred and forty-two patients with recurrent pelvic pain following laparoscopic surgery for endometriosis. Intervention Dienogest (2 mg/day, orally) or depot LA (3.75 mg/4 weeks, intramuscularly) for 12 weeks. Main Outcome Measures A visual analogue scale was used to test the intensity of pain before and after the end of treatment. Results There was highly significant reduction in pelvic pain, back pain and dyspareunia in both groups with mean of difference in dienogest group (28.7 ± 5.3, 19.0 ± 4.3 and 20.0 ± 3.08 mm, respectively) and in LA group (26.2 ± 3.01, 19.5 ± 3.01 and 17.9 ± 2.9 mm, respectively). The most frequent drug-related adverse effects in dienogest group were vaginal bleeding and weight gain (64.5 and 10.8%, respectively) which were significantly higher than LA group (21.5 and 3.3%, respectively). While the most frequent drug-related adverse effects in LA group were hot flushes and vaginal dryness (46.3 and 15.7%, respectively) which were significantly higher than dienogest group (15.7 and 3.3%, respectively). Conclusion Daily dienogest is as effective as depot LA for relieving endometriosis-associated pelvic pain, low back pain and dyspareunia. In addition, dienogest has acceptable safety, tolerability and lower incidence of hot flushes. Thus, it may offer an effective and well-tolerated treatment in endometriosis.

Abstract
INTRODUCTION Endometriosis is a chronic estrogen and progestogen responsive inflammatory disease associated with pain symptoms and infertility. The medical therapy of endometriosis aims to induce decidualization within the hormonally dependent ectopic endometrium, and it is often administered to ameliorate women' pain symptoms or to prevent post-surgical disease recurrence. A variety of progestins have been used in monotherapy for the medical management of women with endometriosis. Areas covered: This review aims to offer the reader a complete overview of pharmacokinetic (PK) and clinical efficacy of progestins for the treatment of endometriosis. Expert opinion: Each progestin has a distinct PK parameters and pharmacodynamics affinity not only for progesterone receptor, but also for other steroid receptors, such as estrogen, androgen, and glucocorticoid. Moreover, progestins can also be delivered in different formulations. All these characteristics influence their final biological effect. Randomized, controlled, non-blinded studies support the use of oral progestin-only treatment for pelvic pain associated with endometriosis. Currently, the only two progestins approved by Food and Drug Administration (FDA) for the treatment of endometriosis are norethindrone acetate (NETA) and depot medroxyprogesterone acetate (DMPA).

Abstract
RATIONALE Many types of pain assessment are available to researchers carrying out clinical trials in chronic pelvic pain (CPP), ranging from a single-item scale to multidimensional inventories. AIM Our objective was to investigate which assessments of pain are more commonly used in clinical trials on CPP. METHOD We have reviewed articles published between 1991 and 2014. A total of 74 studies out of 1299 original research articles reviewed met the selection criteria by containing at least one method of pain assessment. The selected studies were classified according to the dimensions of pain evaluated, the type of scale and the descriptors used. RESULTS The instruments most frequently used were single-item VAS and Biberoglu and Behrman pain score, while multidimensional inventories were used in few studies. The results of clinical studies in CPP are more frequently based on one-dimensional measurements. Valuable results from clinical studies in CPP might have been omitted because of incomplete outcome measurements. CONCLUSION We believe the authors of clinical studies should report their results in a comprehensive way including in the outcomes of the measurement of one-dimensional and multidimensional pain characteristics.

Abstract
Background In four randomized, controlled, European trials, dienogest 2 mg once daily demonstrated significant efficacy for lesion reduction and reduction in pain intensity in endometriosis. We describe a pooled analysis of the safety and tolerability data from these trials to confirm and further characterize the safety profile of dienogest in the treatment of endometriosis. Methods All 332 women treated with dienogest 2 mg who participated in the four clinical trials were included in the pooled analyses for safety assessments, including adverse events, laboratory tests, vital signs, body weight, and bleeding patterns. Safety variables were analyzed using descriptive statistics. Results Pooled analyses of this large patient population confirmed that dienogest 2 mg is well tolerated, with a favorable safety profile extending over a period up to 65 weeks in women with endometriosis. The most common adverse drug reactions were headache, breast discomfort, depressed mood, and acne, each occurring in <10% of women. All these adverse events were generally of mild-to-moderate intensity and associated with low discontinuation rates. The bleeding pattern associated with dienogest 2 mg was well tolerated, and only two women (0.6%) reported bleeding events as the primary reason for premature discontinuation. Laboratory and vital sign assessments indicated no safety concerns for dienogest. Estradiol levels were maintained within the low-physiological range, in support of previous evidence indicating that dienogest 2 mg demonstrates therapeutic efficacy without inducing estradiol deficiency. Conclusion In this pooled analysis of 332 women with endometriosis, dienogest was well tolerated with a favorable safety profile extending over a period of up to 65 weeks. There is a paucity of randomized trial evidence to support the use of many treatments in endometriosis. These pooled analyses from four clinical trials of dienogest 2 mg represent a contribution to evidence-based medicine in endometriosis, providing outcomes of potential relevance to daily practice.

Abstract
Background The aim of this study was to evaluate treatment with dienogest in women with deep infiltrating endometriosis (DIE). Methods A prospective cohort study was conducted at the Department of Gynecology and Obstetrics in the University of Campinas (UNICAMP), Brazil. The study included 16 women with DIE and pain which was not responsive to treatment with other progestins, who were treated with dienogest, and who attend a tertiary university hospital in 2013. Scores for pain complaints, quality of life, sexuality and extent of endometriotic lesions were evaluated before and 6 months after treatment. Statistical methods included the Wilcoxon matched-pairs test, which was used for the analysis of the quantitative data, and the relationship between them was tested by the Spearman correlation index. Results Women were a mean 36 ± 6.2 years old and reported onset of painful symptoms at a mean 29.9 ± 8.6 years of age. A significant reduction in dysmenorrhea, acyclic pelvic pain, dyspareunia and defecation pain was reported after treatment. There was no significant change in the assessment of quality of life or the Female Sexual Function Index. Intestinal lesions, which had an initial 3.4 ± 4.2 cc average size, decreased to 1.6 ± 1.8 cc, but this reduction was not statistically significant. The most common side effects were headaches and acne. Conclusions Dienogest can be used for clinical pain control in DIE.

Abstract
OBJECTIVE This study assessed the relief of uterine bleeding and clinical symptoms during cyclic administration of dienogest for the treatment of endometriosis. METHODS In total, 25 patients undergoing ovarian cyst enucleation and given dienogest participated in this study. Dienogest 2 mg/day was administered for 3 weeks, and the drug was then withdrawn for 1 week (cyclic administration of dienogest). This 4-week cycle was repeated six times. Patients' records were prospectively analyzed for the number of days on which any uterine bleeding occurred, as well as menstrual pain before and after the start of dienogest administration were evaluated with a view to using the data obtained herein as the basis. RESULTS During the period of cyclic administration of dienogest, uterine bleeding occurred on 5.8 to 7.7 days per 4-week period on an average through cycles. Of uterine bleeding episodes, menstruation-like uterine bleeding was present in about 80% of patients. The visual analog scale (VAS) value for menstrual pain significantly decreased from 3.8 before dienogest administration after surgery to 1.5 at the completion of cycle 1, VAS remained low thereafter. CONCLUSION These results raise the possibility that cyclic administration of dienogest may relieve lessen uterine bleeding, a major adverse event and menstrual pain.

Abstract
OBJECTIVE To evaluate patient satisfaction at 6-months dienogest (DNG) treatment in women with symptomatic rectovaginal endometriosis who had pain persistence and were unsatisfied after 6-months of norethisterone acetate (NETA) therapy. STUDY DESIGN This 24-weeks pilot open-label prospective study enrolled 25 women. The main outcome was the degree of patient satisfaction measured by using a Likert scale. Secondary outcomes were to evaluate differences in endometriosis-related pain, quality of life, sexual function changes and volumetric nodules changes during DNG compared to NETA treatment. RESULTS Patient satisfaction improved at 3- and 6-months (p<0.001, respectively) treatment with DNG compared with baseline treatment with NETA. Six months DNG treatment decreased the intensity of all the endometriosis-associated pain (chronic pelvic pain, dyspareunia, dyschezia) compared to baseline (p<0.001 for all comparisons). Quality of life and quality of sexual life evaluated with the EHP-30 and FSFI, respectively, increased after 6 months treatment. The volume of the endometriotic nodules did not significantly change during treatment. CONCLUSIONS This study confirms the efficacy of DNG in treating symptomatic women with rectovaginal endometriosis even in a particular endometriotic subpopulation of NETA "resistant" patients. Further randomized clinical trials comparing these two progestins both in first than second line are warranted.

Abstract
Adenomyosis is a common disorder in premenopausal women that causes dysmenorrhea, pelvic pain and menorrhagia. Considering that adenomyosis is an estrogen-dependent disease, the medical treatment is based on this hormone. Effective and well-tolerated medical treatments for symptomatic adenomyosis are needed. Dienogest, an oral progestin, has been extensively investigated in the treatment of endometriosis. In this report, we present the results on the efficacy and safety of dienogest in the treatment of symptomatic adenomyosis. Seventeen patients with symptomatic adenomyosis were included in this study, of which 15 continued dienogest for up to 24 weeks. Dienogest significantly reduced adenomyosis-associated pelvic pain as well as serum CA-125 and CA19-9 levels. It also demonstrated a modest suppression of estradiol (>50 pg/ mL), which is consistent with the findings of other reports. During treatment, five patients experienced worsening anemia because of metrorrhagia, which is the most frequent adverse effect associated with dienogest. This report suggests that dienogest is an effective and well-tolerated therapy for symptomatic adenomyosis.

Abstract
Endometriosis is one of the most frequent benign diseases in women of child-bearing age. The main symptoms are chronic upper abdominal pain and infertility. However, the aetiology and pathogenesis of endometriosis are as yet insufficiently clarified. Thus, therapy is mainly symptomatic with laparoscopic surgery being the gold standard. The aim of drug therapy is to achieve a hypo-oestrogenic condition. In cases of severe endometriosis and a desire to have children there is often an indication for assisted reproduction. The present article illustrates almost all current aspects on the diagnosis of and therapy of endometriosis. From the clinical viewpoint, emphasis is placed on the rare cases of deeply infiltrating endometriosis that are, however, accompanied with a high morbidity. Current therapeutic options in cases of infertility are also presented in more detail. Furthermore, special attention is paid to the latest research results from both clinical and basic research fields in order to demonstrate our current knowledge on the pathogenesis and, where possible, potentially related therapeutic options.

Abstract
BACKGROUND Numerous studies concerning endometriosis and pain have been reported. However, there is no consensus on the best method to evaluate pain in endometriosis and many scales have been used. Moreover, there are only a few descriptions of minimal clinically important differences after treatment (MCID) to evaluate variations in pain. In our study, we aim to identify pain scales used in endometriosis pain treatment, to address their strong and weak points and to define which would be the ideal scale to help clinicians and researchers to evaluate endometriosis-related pain. METHODS A search of the MEDLINE and EMBASE databases was carried out for publications in English, French or Portuguese from 1980 to December 2012, for the words: endometriosis, treatment, pain. Studies were selected if they studied an endometriosis treatment and a pain scale was specified. A quantitative and a qualitative analysis of each scale was performed to define strong and weak points of each scale (systematic registration number: CRD42013005336). RESULTS A total of 736 publications were identified. After excluding duplications and applying inclusion criteria 258 studies remained. We found that the visual analog scale (VAS) is the most frequently used scale. Both VAS and the numerical rating scale (NRS) show a good balance between strong and weak points in comparison with others such as the Biberoglu and Behrman scale. Concerning MCID, only VAS, NRS and Brief Pain Inventory scales have reported MCID and, among these, only VAS MCID has been studied in endometriosis patients (VAS MCID = 10 mm). Adding the Clinical Global Impression score (CGI) to the pain scale allows calculation of the MCID. CONCLUSIONS When using pain scales their strengths and weaknesses must be known and included in the analysis. VAS is the most frequently used pain scale and, together with NRS, seems the best adapted for endometriosis pain measurement. The use of VAS or NRS for each type of typical pain related to endometriosis (dysmenorrhea, deep dyspareunia and non-menstrual chronic pelvic pain), combined with the CGI and a quality-of-life scale will provide both clinicians and researchers with tools to evaluate treatment response.

Abstract
We have reported good control of atypical genital bleeding when using a cyclic administration of dienogest (repeated 4-week cycles, each consisting of the administration of 2 mg/day of dienogest for 3 weeks, followed by 1 week of drug withdrawal) in patients with endometriosis. Herein, we report the effectiveness of the long-term cyclic administration (22 months) of dienogest in a case of pathological disappearance of intestinal endometriosis diagnosed by endoscopy and histology of the lower gastrointestinal tract. There is no recurrent sign after 16 months of the treatment being stopped. Atypical genital bleeding during treatment was 3–5 days a month in each cycle. Compliance was good, so we could continue the therapy. The long-term cyclic administration of dienogest in patients with intestinal endometriosis may have significant merit.

Abstract
Approaches to the treatment of endometriosis vary worldwide, but studies comparing endometriosis medications in different ethnic groups are rare. A systematic literature search identified two studies directly comparing dienogest (DNG) versus gonadotropin-releasing hormone (GnRH) analogues in European and Japanese populations. Meta-analysis of visual analogue scale scores revealed no heterogeneity in response between the trials, indicating equivalent efficacy of DNG and GnRH analogues for endometriosis-related pain across populations. DNG was significantly superior to GnRH analogues for bone mineral density change in both trials, but significant heterogeneity between the studies may indicate ethnic differences in physiology.

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.
