RESUMO
STUDY OBJECTIVE: To compare the accuracy of preoperative ultrasound (US) in predicting the laparoscopically defined 2021 American Association of Gynecologic Laparoscopists (AAGL) Endometriosis Staging. DESIGN: Retrospective multicenter study of patients treated at 3 specialized endometriosis centers. SETTING: Three specialized endometriosis surgical centers in São Paulo (Brazil), Barcelona (Spain), and Avellino (Italy) participated. PATIENTS: A total of 878 patients aged 15 to 45 years with no history of pelvic malignancy underwent laparoscopic (LPS) treatment for suspected endometriosis. INTERVENTIONS: Retrospective review of preoperative transvaginal and transabdominal US (index test) assessed for endometriosis at all sites used in the 2021 AAGL Endometriosis Classification and classified patients into AAGL-US stages 1 to 4. Results were compared with reference-standard LPS (AAGL-LPS) staging. MEASUREMENTS AND MAIN RESULTS: The AAGL-US and AAGL-LPS stage were concordant in 586 cases (66.7%) (weighted kappa [WK] 0.759; intraclass correlation = 0.906), with the highest agreement observed in patients with no endometriosis (n = 70, 75.3% concordance), AAGL-LPS stage 1 (104, 50.7%) and stage 4 disease (358, 88.2%). Endometriosis was most accurately diagnosed in the rectum/sigmoid colon (WK 0.862), bladder (WK 0.911), and ovaries (WK 0.835/0.795 for right/left, respectively) and least accurately diagnosed at superficial peritoneal (WK 0.442), tubal (WK 0.391/0.363 for right/left, respectively), and retrocervical/uterosacral ligament (WK 0.656) sites. CONCLUSION: Sonographic estimation of the 2021 AAGL Endometriosis Staging is greatest in AAGL-LPS stages 1 and 4 and among patients with no endometriosis. US best identifies endometriosis of the ovaries, bladder, and bowel but is more limited for the tubes and superficial peritoneum.

OBJECTIVE: To evaluate the frequencies of iNKT cells and their subsets in patients with deep endometriosis. METHODS: A case-control study was conducted between 2013 and 2015, with 73 patients distributed into two groups: 47 women with a histological diagnosis of endometriosis and 26 controls. Peripheral blood, endometriosis lesions, and healthy peritoneal samples were collected on the day of surgery to determine the frequencies of iNKT cells and subtypes via flow cytometry analysis. RESULTS: The authors observed a lower number of iNKT (p = 0.01) and Double-Negative (DN) iNKT cells (p = 0.02) in the blood of patients with endometriosis than in the control group. The number of DN iNKT IL-17+ cells in the secretory phase was lower in the endometriosis group (p = 0.049). There was an increase in the secretion of IL-17 by CD4+ iNKT cells in the blood of patients with endometriosis and severe dysmenorrhea (p = 0.038), and severe acyclic pelvic pain (p = 0.048). Patients with severe dysmenorrhea also had a decreased number of CD4+ CCR7+ cells (p = 0.022). CONCLUSION: The decreased number of total iNKT and DN iNKT cells in patients with endometriosis suggests that iNKT cells play a role in the pathogenesis of endometriosis and can be used to develop new diagnostic and therapeutic agents.

INTRODUCTION: Endometriosis is a chronic inflammatory disease that affects approximately 10%-15% of women of childbearing age. Laparoscopic surgery is the preferred surgical approach. Recently, robotic surgery has been used for benign gynecologic surgery, but its role in the treatment of endometriosis is still unknown. AREAS COVERED: We included studies that evaluated the outcomes of robotic surgery for endometriosis. Using the keywords 'endometriosis' and 'robotics', a comprehensive literature search on PubMed, Embase, and the Cochrane Library was performed in July 2021. EXPERT OPINION: Robotic surgery for endometriosis has similar outcomes as conventional laparoscopy, with no evidence of increased complication rates. Despite the non-inferiority of the surgical route, the associated costs of robotic surgery limit its availability. Rapid development of robot-assisted surgery necessitates long-term prospective randomized controlled trials. However, the limitations of robotic surgery should not be overlooked. If robotic surgery can facilitate the spread of minimally invasive surgery, it will be necessary to evaluate the cost, availability, complexity of the lesions, and most importantly, the results of patient satisfaction and values of value-based medicine.

RESUMO
STUDY OBJECTIVE: To develop a new endometriosis classification system for scoring intraoperative surgical complexity and to examine its correlation with patient-reported pain and infertility. DESIGN: Multicenter study of patients treated at 3 recognized endometriosis centers. SETTING: Three specialized endometriosis surgical centers in São Paulo, Brazil and Barcelona, Spain. PATIENTS: Patients aged 15 to 45 years with histologically proven endometriosis and no history of pelvic malignancy underwent laparoscopic treatment of endometriosis. INTERVENTIONS: Demographic data and clinical history, including dysmenorrhea, noncyclic pelvic pain, dyspareunia, dysuria and dyschezia, were prospectively recorded. All patients were staged surgically according to the new 2021 American Association of Gynecologic Laparoscopists (AAGL) and revised American Society of Reproductive Medicine (ASRM) classification systems. The staging for each system was compared against a 4-level surgical complexity scale defined by the most complex procedure performed. MEASUREMENTS AND MAIN RESULTS: A total of 1224 patients undergoing surgery met inclusion criteria. The AAGL score discriminated between 4 stages of surgical complexity with high reproducibility (κ = 0.621), whereas the ASRM score discriminated between the complexity stages with poor reproducibility (κ = 0.317). The AAGL staging system correlated with dysmenorrhea, dyspareunia, dyschezia, total pain score, and infertility comparably with the ASRM staging system. CONCLUSION: The AAGL 2021 Endometriosis Classification allows for identifying objective intraoperative findings that reliably discriminate surgical complexity levels better than the ASRM staging system. The AAGL severity stage correlates comparably with pain and infertility symptoms with the ASRM stage.

BACKGROUND: Human endometrium harbors stem/progenitor cells (SPCs) that may contribute to the establishment of endometriosis when seeded outside the uterus. Oct-4, C-kit and Musashi-1 are some of the many proteins used to characterize SPCs, but their association with endometriosis is uncertain. OBJECTIVE AND DESIGN: In this study, specimens of normal endometrium (n = 12), eutopic endometrium from women with endometriosis (n = 9), superficial peritoneal endometriosis (SUP, n = 12) and deep endometriosis (DE, n = 13) lesions were evaluated for localization and intensity of immunostaining for Oct-4, C-kit and Musashi-1. RESULTS: The three markers were abundantly expressed in normal endometrium, eutopic endometrium from endometriosis patients, SUP and DE specimens. Oct-4 and C-kit expression did not vary across groups as regards intensity or frequency. C-kit staining signal was seldom detected in vascular endothelium of normal or eutopic endometrium from endometriosis patients; however, it was positive in 67% of the SUP lesions and in 25% of the DE lesions (p = 0.042). Musashi-1 was expressed in some endometriotic glands as cell clusters, but its signal was similar between the four types of tissue (p = 0.971) CONCLUSION: The wide distribution of Oct-4, C-kit and Musashi-1 in endometria of patients with and without endometriosis and in SUP and DE endometriotic lesions suggests that these markers are not suitable for the in situ characterization of endometrial SPCs and should not be taken as surrogates for the study of SPCs in the pathogenesis of endometriosis.

BACKGROUND: Elagolix is an oral, gonadotropin-releasing hormone (GnRH) receptor antagonist, that significantly reduces dysmenorrhea and non-menstrual pelvic pain (NMPP) in women with moderate to severe endometriosis-associated pain. METHODS: Data were pooled from two 6-month, placebo-controlled, phase 3 studies (Elaris Endometriosis [EM]-I and II) in which 2 doses of elagolix were evaluated (150 mg once daily and 200 mg twice daily). Pooled data from > 1600 women, aged 18-49, were used to evaluate the efficacy of elagolix and health-related quality of life (HRQoL) in prespecified subgroups of women with various baseline characteristics. RESULTS: Of the 1686 women treated, 1285 (76.2%) completed the studies. The percentages of women with clinically meaningful reductions in dysmenorrhea and NMPP were generally consistent by subgroup. Significant treatment by subgroup interaction was demonstrated for dysmenorrhea response in baseline analgesic use (p < 0.01) and previous history of pregnancy (p < 0.05) subgroups, and for NMPP response in the baseline NMPP score (p < 0.05) and history of pregnancy (p < 0.05) subgroups. Patient-reported reduction in pain at month 3 was significant across all subgroups taking elagolix 200 mg BID, and significant across most subgroups with elagolix 150 mg QD. Women across subgroups experienced improvement within each domain of the Endometriosis Health Profile-30 (EHP-30), although significant treatment by subgroup interactions were observed in several categories. CONCLUSIONS: Elagolix was effective in reducing dysmenorrhea and NMPP, and improving HRQoL, compared with placebo across numerous subgroups of women with various baseline characteristics, covering a broad segment of the endometriosis disease and patient types.

Deep endometriosis (DE) is classically defined as disease that infiltrates structures by more than 5 mm, such as bowel, ureters, bladder and vagina. The two major symptoms related to DE are pain and infertility. A lot of debate goes on upon the best treatment choice for DE. Treatments include medical therapy with oral progestins or combined contraceptives, and surgery for resection of DE nodules. In this review we focus on the best option treatment for the symptomatic patients with DE not seeking conception. We performed a narrative review of literature searching for the latest evidence on efficacy and outcomes of medical and surgical treatment of DE patients. Results showed that 2/3 of patients with DE will be satisfied with hormonal treatment, and surgery will be effective in improving QoL in most patients with DE. Most studies published regarding surgical outcomes involve bowel endometriosis, and their complication rates should not be extrapolated to all DE. DE that does not infiltrate pelvic viscera accounts for most cases of DE. Together with DE affecting the urinary tract, a much lower rate of severe complications is reported when compared to bowel endometriosis. This distinction should influence decision making. Medical treatment should be first option for non-complicated DE patients not seeking conception. Surgery should be indicated for those who do not tolerate nor improve with medical treatment, as well as those cases complicated by visceral impairment.

INTRODUCTION: The prevalence of appendiceal endometriosis ranges from 0.4% to 22%. The carcinoid tumor is the most common neoplasm of the appendix, with incidence ranging from 0.3% to 0.9%. Appendix lesions develop in up to 22% of women with deep infiltrative endometriosis. Even though these are most likely endometriosis, carcinoid tumors should always be considered. The aim of this review was to assess the prevalence of appendiceal carcinoid tumors and appendiceal endometriosis in patients undergoing gynecologic surgery, its association with endometriosis, and related symptoms. EVIDENCE ACQUISITION: We included retrospective and prospective studies that assessed women who underwent appendicectomy in the past 20 years for appendiceal endometriosis and/or appendix carcinoid tumor confirmed by histological analysis. Results were reported as relative and absolute frequencies. Due to the heterogeneity of included studies, a statistical analysis (meta-analysis) was not performed. EVIDENCE SYNTHESIS: The prevalence of appendiceal endometriosis was 15.2% in patients who underwent surgery for pelvic endometriosis and 11.4% in those who underwent benign gynecological surgery. Conversely, carcinoid tumors of the appendix were present in 2.4% of endometriosis patients and 1.3% of other benign gynecological surgeries. CONCLUSIONS: The rates of carcinoid tumors in patients with endometriosis are the same as in the general population. Given the risk of a malignant appendiceal tumor, in all gynecological surgeries, especially those for endometriosis, the appendix should be inspected and removed if it has an abnormal appearance.

STUDY QUESTION: What is the sensitivity and the specificity of preoperative transvaginal ultrasound with bowel preparation (TVUS-BP) compared to diagnostic laparoscopy (DL) for the identification of ovarian and deep sites of endometriosis? SUMMARY ANSWER: DL was able to detect retrocervical, ovarian, and bladder endometriosis with similar sensitivity and specificity as TVUS-BP, whereas for vaginal and rectosigmoid endometriosis, DL had lower sensitivity and specificity than TVUS-BP. WHAT IS KNOWN ALREADY: TVUS-BP is a non-invasive examination with good accuracy for diagnosing ovarian and deep endometriosis. DL is expensive and can lead to surgical complications. STUDY DESIGN, SIZE, DURATION: This prospective study included a total of 120 consecutive patients who underwent surgery for suspected endometriosis with preoperative imaging (TVUS-BP), including a video of the laparoscopic procedure, between March 2017 and September 2019. PARTICIPANTS/MATERIALS, SETTING, METHODS: Two radiologists performed preoperative TVUS-BP using the same protocol for diagnosing endometriosis. Two surgeons, who were blinded to the results of the preoperative imaging and clinical data, reviewed the surgical videos from the entry of the abdominal cavity until the surgeon finalized a complete and systematic review prior to beginning any dissection (considered as a DL). A data sheet was used by surgeons and radiologists to record the sites and size of disease involvement, the American Society for Reproductive Medicine (ASRM) stage, and the Enzian score. The surgical visualization of endometriosis lesions that were confirmed by histological analysis was the gold standard. MAIN RESULTS AND THE ROLE OF CHANCE: DL was able to detect retrocervical, ovarian, and bladder endometriosis with similar sensitivity and specificity as TVUS-BP. DL was not able to detect vaginal endometriosis (sensitivity and specificity 0%): this is compared to a sensitivity and specificity of 85.7% and 99.1%, respectively with the utilization of a preoperative TVUS-BP. In addition, DL was notably poor at detecting rectosigmoid endometriosis, with a sensitivity of 3.7-5.6%, and this compares to 96.3% sensitivity with utilization of a preoperative TVUS (P < 0.001). For the ASRM stage, TVUS-BP results were highly correlated with the degree of endometriosis and pouch of Douglas (POD) obliteration (weighted Kappa of 0.867 and 0.985, respectively). For the Enzian score, there was a substantial correlation between TVUSP-BP and DL for compartment A (weighted Kappa = 0.827), compartment B (weighted Kappa = 0.670), and compartment C (weighted kappa = 0.814). LIMITATIONS, REASONS FOR CAUTION: The number of participants included may be a limitation in this study and, as the evaluators were blinded to the physical exam, the DL accuracy could be underestimated. As biopsies of pelvic organs were obtained only if there was a suspicion of endometriosis, the gold standard was not always applicable. This aspect could underestimate the prevalence of lesions and overestimate the sensitivity and the specificity of both the TVUS-BP and the DL. WIDER IMPLICATIONS OF THE FINDINGS: Preoperative TVUS-BP was accurate in identifying all sites of ovarian and deep endometriosis that were evaluated. It had significantly higher sensitivity than DL in detecting rectosigmoid endometriosis and predicting intraoperative ASRM staging and the Enzian score. These results suggest that TVUS-BP can replace DL for the diagnosis and treatment planning for patients with ovarian and deep endometriosis.

OBJECTIVE: Endometriosis has a complex and multifactorial pathology, and it is considered one of the main causes of infertility nowadays. The angiogenic process, which involves remodeling of extracellular matrix, is crucial for the development of this disease, mainly by the action of the matrix metalloproteinase 3 (MMP-3). It is known that genetic factors can influence endometriosis, thus; we investigated the role of MMP3 276G>A polymorphism as a risk factor for the development of the disease and its symptoms. STUDY DESIGN: This case-control study included 283 women with endometriosis (cases) and 217 women without the disease (controls) who were submitted to laparoscopic or laparotomy surgery. Real-time polymerase chain reaction performed by TaqMan system was applied for all polymorphisms. A multivariate logistic regression was performed to evaluate the association between polymorphism and endometriosis or clinical and gynecological characteristics of the disease, using their respective odds ratios (OR) and 95% confidence intervals (CI). RESULTS: The allelic frequency of the MMP3 276 G > A polymorphism was 33.6% in controls and 40.3% in endometriosis cases. The allelic distribution was significantly different between the two (P = 0.03). The variant genotype of MMP3 276AA was associated with increased endometriosis risk in the advanced endometriosis cases (OR: 2.08, 95% CI: 1.05 - 4.07 and OR: 1.87, 95% CI: 1.01 - 3.45). Regarding the symptoms, endometriosis-related infertile women had a positive association with the presence of MMP3 276 G > A polymorphism (OR: 3.13, 95% CI: 1.08-9.08 and OR: 3.30, 95% CI: 1.31 - 8.33). CONCLUSIONS: These findings suggest that the MMP3 276A polymorphism is involved with advanced endometriosis cases and infertility, and these associations may implicate in the behavior of disease.
RESUMO
OBJECTIVE: To assess whether the HLA-G immunomodulatory protein is potentially involved in the pathophysiology of endometriosis or disease progression. STUDY DESIGN: Cross-sectional observational study of 227 women who underwent laparoscopy, being 146 for endometriosis excision and 81 for elective tubal ligation (control group). Soluble HLA-G (sHLA-G) levels in the serum and peritoneal fluid (PF), as well as the HLA-G protein expression in matched eutopic and ectopic endometrium of women with and without endometriosis were evaluated by ELISA and immunohistochemistry assays, respectively. Women with endometriosis were separated into groups according to the initial (I/II, n = 60) and advanced (III/IV, n = 86) stages of disease. sHLA-G measurement was performed only in women with matched serum and PF samples in both the control (CTRL; n = 77) and endometriosis (EDT; I-II, n = 60; III-IV, n = 83) groups. HLA-G protein expression was evaluated in 26 women with deep endometriosis (I-II, n = 12; III-IV, n = 14) and 22 controls. RESULTS: Higher concentrations of sHLA-G (P = 0.013) in the serum but not in the PF were observed in women with advanced endometriosis compared to the control group. In situ expression of HLA-G protein was also higher in ectopic (P = 0.018) but not in eutopic endometrium of women with advanced endometriosis compared to control group. CONCLUSION: Our findings suggest that HLA-G upregulation in advanced stages may contribute to the state of immunosuppression in endometriosis as disease progresses.

OBJECTIVE: To detect Mollicutes in women with endometriosis and healthy peritoneal tissues and evaluate the participation of these bacteria in the immune response during endometriosis. DESIGN: Cross-sectional study. SETTING: University hospitals. PATIENT (S): Women with endometriosis (n = 73) and without endometriosis (n = 31). INTERVENTION(S): Endocervical swabs, peritoneal fluid, and biopsied lesions of endometriosis of women with endometriosis (study group) and healthy peritoneal tissues (control group) were collected during surgery. Clinical characteristics were registered before surgery. MAIN OUTCOME MEASURE(S): We determined the infectious agents with the use of quantitative polymerase chain reaction (PCR). The cytokine secretion profile was determined with the use of Luminex. The expression of immune response related genes was determined with the use of a PCR array kit. RESULT(S): All target microorganisms were detected at least once in the swab samples analyzed. It was possible to observe higher diversity of microorganisms in the samples of swab and peritoneal fluid in the study group compared with the control. Ureaplasma parvum was associated with the severity of the symptom dyspareunia. Mycoplasma genitalium was associated with higher production of interferon-γ and interleukin-1ß. Genes of inflammatory response activation and antigen presentation were up-regulated in biopsied tissue of women with endometriosis. In women with endometriosis, peritoneal fluid cells showed a down-regulation of genes associated with the inflammatory response. This down-regulation profile was higher in presence of M. genitalium. CONCLUSION(S): Mycoplasma genitalium may play a key role in the immune tolerance process and, especially, the aggravation of this profile. More studies are needed to understand this immune tolerance profile of bacterial infections.

INTRODUCTION: Endometriosis is a chronic inflammatory disease that affects young women in reproductive age. It has mainly three different clinical presentations: superficial (peritoneal), ovarian (endometriomas) and deep endometriosis (DE). The last one is the most advanced form of the disease, frequently impairing fertility and harming women's quality of life (QoL). EVIDENCE ACQUISITION: We conducted a systematic review on the surgical treatment of DE in the last ten years focusing on its benefits to improve QoL and for pain relief as well as related surgical complications. EVIDENCE SYNTHESIS: Twenty-three studies were included for qualitative analysis. Overall, included studies showed a relevant improvement in QoL as well as in pain scores using specific questionnaires and the ten-point Visual Analogue Scale (VAS) for pain. CONCLUSIONS: Until further comparative studies regarding medical versus surgical treatment for DE are concluded, currently, surgery is the best option for patients with DE and severe pain (VAS>7).

Review of literature is conducted to determine the best minimally invasive hysterectomy (MIH) route for large uterus, identify preoperative considerations and describe alternative techniques to power morcellation. Studies after 2010 revealed multiple MIH approaches. Vaginal hysterectomy is preferred over laparoscopic and laparoscopic assistance with less operative time and hospital cost. In morbidly obese patients with large uteri, total laparoscopic hysterectomy is superior to vaginal hysterectomy with lesser odds of blood transfusion and lower length of hospital stay. Although MIH for the large uterus is feasible, many questions remain unanswered. Well-designed multicenter prospective trial incorporating clinical pathways to compare outcomes is needed.

STUDY OBJECTIVE: To show a step-by-step laparoscopic approach for excision of an ovarian endometrioma following surgical principles for safety and maximal preservation of ovarian function. DESIGN: Video. Medical management of ovarian endometriomas is not recommended. Operative laparoscopy is the treatment of choice. Although considered a simple procedure, ovarian cystectomy requires a precise and correct technique in order to preserve ovarian function. SETTING: A private hospital. PATIENT: An asymptomatic, 27-year-old woman with ultrasound imaging suggesting a 6.2 × 5.4 cm left endometrioma. Additional findings of endometriotic implants were noted in the posterior aspect of the left broad ligament, retrocervical region, Douglas pouch, and left round ligament. INTERVENTIONS: After trocar insertion, standard inspection of the pelvic cavity with identification of endometriosis lesions and adhesions was performed. The endometrioma was drained with direct trocar puncture to avoid spillage of the endometriotic contents. Cyst aspiration and saline cleaning were executed. After drainage, a cold cut was performed at the puncture site for better identification of the cyst capsule. Through gentle traction and countertraction, the capsule was peeled from the ovarian cortex, preserving as much ovarian tissue as possible followed by careful hemostasis with a bipolar instrument. The ovary is fixed, anatomy re-established, and concomitant pelvic endometriosis resected. We aim for complete surgical excision in order to avoid leaving disease behind. The ovarian edges were reapproximated using simple interrupted stitches. MEASUREMENTS AND MAIN RESULTS: The total procedure time was 40 minutes. CONCLUSION: Laparoscopic endometrioma stripping offers an effective option for ovarian endometriosis treatment, reducing recurrence and being reproducible by gynecologic surgeons after proper training.

STUDY QUESTION: Is mRNA expression of LDL receptors altered in deep bowel endometriotic foci? SUMMARY ANSWER: mRNA expression of LDL receptors is up-regulated in deep bowel endometriotic foci of patients with endometriosis. WHAT IS KNOWN ALREADY: Several studies have demonstrated the overexpression of low-density lipoprotein receptors in various tumour cell lines and endometriosis has similar aspects to cancer, mainly concerning the pathogenesis of both diseases. This is the first study we know of to investigate lipoprotein receptors expression in deep endometriosis with bowel involvement. STUDY DESIGN, SIZE, DURATION: During 2014-2015, an exploratory case-control study was conducted with 39 patients, including 20 women with a histological diagnosis of deep endometriosis compromising the bowel and 19 women without endometriosis who underwent laparoscopic tubal ligation. PARTICIPANTS/MATERIALS, SETTING, METHODS: Peripheral blood samples were collected on the day of surgery for lipid profile analysis, and samples of endometrial tissue and of bowel endometriotic lesions were also collected. The tissue samples were sent for histopathological analysis and for LDL-R and LRP-1 gene expression screening using quantitative real-time PCR. MAIN RESULTS AND THE ROLE OF CHANCE: Patients with deep endometriosis had lower LDL-cholesterol than patients without the disease (119 ± 23 versus 156 ± 35; P = 0.001). Gene expression analysis of LDL receptors revealed that LDL-R was more highly expressed in endometriotic lesions when compared to the endometrium of the same patient but not more than in the endometrium of women without endometriosis (0.027 ± 0.022 versus 0.012 ± 0.009 versus 0.019 ± 0.01, respectively; P < 0.001). LRP-1 was more highly expressed in endometriotic lesions, both when compared with the endometrium of the same patient and when compared with the endometrium of patients without the disease (0.307 ± 0.207 versus 0.089 ± 0.076 and versus 0.126 ± 0.072, respectively; P < 0.001). The study also showed that LDL-R gene expression in the endometrium of women with endometriosis was higher during the secretory phase of the menstrual cycle (P = 0.001). LRP-1 gene expression was increased during the secretory phase in the endometrium of women without the disease (P = 0.008). LIMITATIONS, REASONS FOR CAUTION: In the endometriotic lesions, the presence of fibrosis is substantial, restricting access to the stromal and glandular components of the lesion. Despite that, we found that LDL receptor mRNA was overexpressed. Future studies may perform laser microdissection to isolate the area of interest in the target tissue, excluding fibrosis contamination. WIDER IMPLICATIONS OF THE FINDINGS: This study supports the feasibility of LDL-R targeted therapy in the treatment of deep endometriosis. STUDY FUNDING/COMPETING INTERESTS: This study was supported by Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP #2011/17245-0). The authors have no conflicts of interest to declare.
