RESUMEN
OBJECTIVE: To describe how the knowledge from standard imaging practices can be translated into three-dimensional visualization techniques and utilized in the surgical planning and management of endometriosis. SETTING: Tertiary care academic centre. PARTICIPANTS: Two case studies of patients with endometriosis are described. INTERVENTIONS: Transvaginal ultrasound (1), magnetic resonance imaging, three-dimensional printing (2), and three-dimensional virtual reality modeling (3) were utilized during patient workup and preparation. Three-dimensional modeling was performed by a virtual reality technician and verified for accuracy by a fellowship trained radiologist. Surgical management for endometriosis was performed. CONCLUSION: While expert transvaginal ultrasound and/or magnetic resonance imaging suffice for the majority of cases, three-dimensional printing and virtual reality modeling are a novel adjunct to standard imaging modalities. Rendering two-dimensional images into a three-dimensional representation allows users to interact with the anatomy and is particularly useful when distorted by complex pathology. These techniques contributed to improved patient understanding and experience, and helped medical learners better grasp regular imaging techniques and its translation to pelvic anatomy. Last, it augmented surgeon comprehension of the relationship between the pelvic structures, allowing for enhanced surgical planning and intraoperative decision making. Further study is being performed to quantify these effects.
RESUMEN
To provide a contemporary approach to the understanding of the impact and methods for the diagnosis of endometriosis in Canada. Individuals, families, communities, health care providers, and health care administrators who are affected by, care for patients with, or manage delivery of services for endometriosis. The diagnosis of endometriosis is facilitated by a detailed history, examination, and imaging tests with providers who are experienced in endometriosis care. Surgical evaluation with pathology confirms a diagnosis of endometriosis; however, it is not required for those whose diagnosis was confirmed with imaging. There is a need to address earlier recognition of endometriosis to facilitate timely access to care and support. Education directed at the public, affected individuals and families, health care providers, and health care administrators are essential to reduce delays in diagnosis and treatment. Increased awareness and education about the impact and approach to diagnosis may support timely access to care for patients and families affected by endometriosis. Earlier and appropriate care may support a reduced health care system burden; however, improved clinical evaluation may require initial investments. Each section was reviewed with a unique search strategy representative of the evidence available in the literature related to the area of focus. The literature searches for each section of this guideline are listed in Appendix A and include information from published systematic reviews described in the text. The recommendations were developed following two rounds of review by a national expert panel through an iterative 2-year consensus process. Further details on the process are shared in Appendix B. The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See Appendix C (Table C1 for definitions and Table C2 for interpretations of strong and conditional recommendations). This guideline is intended to support health care providers and policymakers involved in the care of those impacted by endometriosis and the systems required to support them.

The Heavy menstrual bleeding: Evidence-based Learning for best Practice (HELP) Group developed an educational website about heavy menstrual bleeding (HMB). The "HMB improving Outcomes with Patient counseling and Education" (HOPE) project examined the website's impact on women's knowledge, confidence, and consultations with healthcare providers (HCPs). HOPE was a quantitative online survey of gynecologists and women with HMB in Brazil. After an initial consultation, patients had unlimited access to the website and completed a survey. HCPs also completed a survey about the sconsultation. After a second consultation, HCPs and patients completed another survey. HCP surveys assessed their perception of patients' awareness, understanding, and willingness to discuss HMB. Patient surveys assessed their knowledge, experience, and confidence in discussing HMB. Forty HCPs recruited 400 women with HMB. Based on HCP perceptions at the first consultation, 18 percent of patients had "good knowledge" or "very good knowledge" of HMB, increasing to 69 percent after patients had visited the website. Before and after visiting the website, 34 percent and 69 percent of patients, respectively, regarded their HMB knowledge as "goo.d" Additionally, 17 percent of women reported their anxiety as "highest" during the first consultation; this decreased to 7 percent during the second consultation. After visiting the HELP website, patients' knowledge of HMB improved and they were less anxious.

OBJECTIVES: Describe the current practice of Canadian obstetricians-gynaecologists in managing placenta accreta spectrum (PAS) disorders from suspicion of diagnosis to delivery planning and explore the impact of the latest national practice guidelines on this topic. METHODS: We distributed a cross-sectional bilingual electronic survey to Canadian obstetricians-gynaecologists in March-April 2021. Demographic data and information on screening, diagnosis, and management were collected using a 39-item questionnaire. The survey was validated and pretested among a sample population. Descriptive statistics were used to present the results. RESULTS: We received 142 responses. Almost 60% of respondents said they had read the latest Society of Obstetricians and Gynaecologists of Canada clinical practice guideline on PAS disorders, published in July 2019. Nearly 1 in 3 respondents changed their practice following this guideline. Respondents highlighted the importance of 4 key points: (1) limiting travel to thereby remain close to a regional care centre, (2) preoperative anemia optimization, (3) performance of cesarean-hysterectomy leaving the placenta in situ (83%), (4) access via midline laparotomy (65%). Most respondents recognized the importance of perioperative blood loss reduction strategies such as tranexamic acid and perioperative thromboprophylaxis via sequential compression devices and low-molecular-weight heparin until full mobilization. CONCLUSIONS: This study demonstrates the impact of the Society of Obstetricians and Gynaecologists of Canada's PAS clinical practice guideline on management choices made by Canadian clinicians. Our study highlights the value of a multidisciplinary approach to reducing maternal morbidity in individuals facing surgery for a PAS disorder and the importance of regionalized care that is resourced to provide maternal-fetal medicine and surgical expertise, transfusion medicine, and critical care support.

OBJECTIVE: Developments in 3-dimensional (3D) printing technology has made it possible to produce high quality, affordable 3D printed models for use in medicine. As a result, there is a growing assessment of this approach being published in the medical literature. The objective of this study was to outline the clinical applications of individualized 3D printing in gynecology through a scoping review. DATA SOURCES: Four medical databases (Medline, Embase, Cochrane CENTRAL, Scopus) and grey literature were searched for publications meeting eligibility criteria up to 31 May 2021. STUDY ELIGIBILITY CRITERIA: Publications were included if they were published in English, had a gynecologic context, and involved production of patient specific 3D printed product(s). STUDY APPRAISAL AND SYNTHESIS METHODS: Studies were manually screened and assessed for eligibility by two independent reviewers and data were extracted using pre-established criteria using Covidence software. RESULTS: Overall, 32 studies (15 abstracts,17 full text articles) were included in the scoping review. Most studies were either case reports (12/32,38%) or case series (15/32,47%). Gynecologic sub-specialties in which the 3D printed models were intended for use included: gynecologic oncology (21/32,66%), benign gynecology (6/32,19%), pediatrics (2/32,6%), urogynecology (2/32,6%) and reproductive endocrinology and infertility (1/32,3%). Twenty studies (63%) printed 5 or less models, 6/32 studies (19%) printed greater than 5 (up to 50 models). Types of 3D models printed included: anatomical models (11/32,34%), medical devices, (2/32,6%) and template/guide/cylindrical applicators for brachytherapy (19/32,59%). CONCLUSIONS: Our scoping review has outlined novel clinical applications for individualized 3D printed models in gynecology. To date, they have mainly been used for production of patient specific 3D printed brachytherapy guides/applicators in patients with gynecologic cancer. However, individualized 3D printing shows great promise for utility in surgical planning, surgical education, and production of patient specific devices, across gynecologic subspecialties. Evidence supporting the clinical value of individualized 3D printing in gynecology is limited by studies with small sample size and non-standardized reporting, which should be the focus of future studies.
RESUMEN
Although laparoscopy has classically been defined as the gold standard for diagnosis of endometriosis, there is now a strong recommendation for the use of advanced imaging in diagnosing the disease. In addition to playing a crucial role in the diagnosis of endometriosis, advanced imaging is also essential for assisting gynaecologic surgeons in planning the surgical management of complex cases of deep endometriosis. This case demonstrates a metaverse of high-level imaging modalities, including advanced ultrasound and magnetic resonance, which were further enhanced with medical virtual reality and used for the assessment of a patient seen in an outpatient tertiary care gynaecology clinic.

Heavy menstrual bleeding (HMB) has an estimated prevalence of 18-32% but is known to be under-reported due to poor recognition and estimation of menstrual blood loss (MBL). HMB can negatively impact quality of life, affecting social interactions, work productivity and sexual life. Abnormal menstrual bleeding may have an underlying structural or systemic cause, such as endometrial and myometrial disorders; however, for some, there is no identified pathological cause. Several methods are available for assessing MBL, including the alkaline hematin (AH) method and the menstrual pictogram (MP). The AH method is considered to be the most accurate way to monitor MBL; however, it is associated with inconvenience and expense, therefore limiting its value outside of research. The MP requires the user to select an icon from a chart that reflects the appearance of a used sanitary product; the icon is associated with a blood volume that can be used to determine MBL. Validation studies have demonstrated that the results of the MP and AH method are well correlated, showing that the MP can measure MBL with sufficient accuracy. Additionally, the MP is more convenient for users, less expensive than the AH method, may be used in regions where the AH method is unavailable and may also be used as part of a digital application. Overall, the MP offers a convenient approach to monitor MBL both in research and clinical practice settings.
RESUMEN
BACKGROUND: Failure to obtain an office-based endometrial biopsy for abnormal uterine bleeding is not uncommon. Although operating room-based procedures are traditionally considered the gold standard assessment tool in these circumstances, outpatient hysteroscopy is a less invasive, more cost-effective, and safer alternative. However, there is no contemporary Canadian literature on the effectiveness of an outpatient approach for this specific population. OBJECTIVE: We aim to evaluate the effectiveness and outcomes of outpatient hysteroscopy for uterine cavity evaluation for patients who have failed an in-office endometrial biopsy attempt. METHODS: We conducted a retrospective cohort study of all patients referred to an academic outpatient hysteroscopy unit between January 2015 and January 2018, who underwent an outpatient hysteroscopy following failed endometrial biopsy. Data were collected from electronic medical records. RESULTS: Of the 407 consecutive patients who underwent an outpatient hysteroscopic procedure, 68 met inclusion criteria. Postmenopausal bleeding was the most common indication for initial biopsy, and most failures were attributed to cervical stenosis. Outpatient hysteroscopies were successfully completed in 96% of cases (n = 65/68). Failure resulted from either anxiety and discomfort (n = 2), or severe intrauterine adhesions (n = 1). Overall, 10% of patients subsequently required an operating room-based hysteroscopy, either to complete a myomectomy or polypectomy, or to allow general anesthesia. Outpatient hysteroscopy identified endometrial hyperplasia and cancer in 4.5% and 3% of patients, respectively. CONCLUSION: Outpatient hysteroscopy following unsuccessful office endometrial biopsy attempts appears to be a feasible, safe, and cost-effective investigation strategy that may prevent the need for an operating room-based procedure in 90% of cases.

Endometriosis, affecting 5-10% of reproductive-age women, is a common contributor to dysmenorrhea and chronic pelvic pain. Diagnosis requires laparoscopic tissue biopsy, but careful pelvic examination, and/or imaging with either ultrasound or MRI, may identify patients who should receive empiric first-line therapy. The presence of dyschezia, particularly with cyclical exacerbation, should raise suspicion for bowel or rectovaginal septum involvement, and a greater need for surgical management. Treatment of dysmenorrhea includes hormonal suppression of the menstrual cycle, and/or analgesics; more severe cases with strong pain and disability may require earlier surgical intervention to excise disease while preserving fertility desires.

Uterine fibroids are common benign tumors that occur in up to 80% of women. Approximately half of the women affected experience considerable physical, psychological, and economic burdens and impact on quality of life due to symptoms such as heavy menstrual bleeding, pelvic pain, and infertility. Several medical and surgical options are available to treat uterine fibroids; however, healthcare providers may benefit from practical guidance in the development of individualized treatment plans based on a personalized approach. Medical treatments and minimally invasive procedures are generally preferred by most patients before considering more invasive, higher risk surgical interventions. In general, patient-centered, uterine-preserving procedures may be prioritized based on the patient's goals and the clinical scenario. Occasionally, hysterectomy may be the preferred treatment option for some patients who require definitive treatment. This call-to-action highlights recent challenges to patient care, including radical shifts in physician-patient interactions due to the COVID-19 pandemic and recent changes to evidence-based, clinically approved therapies. This report also reviews contemporary recommendations for women's health providers in the diagnosis and medical and surgical management of uterine fibroids. This call-to-action aims to empower healthcare providers to optimize the quality of care for women with uterine fibroids utilizing the best available evidence and best practices.

OBJECTIVE: To identify 1) the current state of pediatric and adolescent gynecology (PAG) provision of care; 2) barriers to practicing PAG; and 3) the need for increased PAG training in residency and continuing medical education (CME). METHODS: Obstetricians and gynecologists (OB/GYNs) across Canada who currently practice gynecology were asked to complete an anonymous, self-administered, Internet-based survey. RESULTS: One-hundred and forty-seven OB/GYNs across Canada responded to the survey, and after applying exclusion criteria (retired gynecologists, medical students, postgraduate trainees, gynecologists who do not currently practice gynecology, PAG specialists, or OB/GYNs seeing predominantly pregnant adolescent women), 135 were included. Seventy-six percent of survey respondents stated that they care for pediatric and adolescent patients in their practice. The pathologies and surgeries they are comfortable managing are those that are similar to the adult population, such as intrauterine device insertion in the office/OR, adnexal detorsion, laparoscopy in patients over 12 years of age, examination under anesthesia, and hymenectomy. Respondents who stated wanting to learn more about PAG preferred either online learning modules (85%) or CME workshops at regional meetings (91%). CONCLUSION: Canadian OB/GYNs provide PAG care with very little training to support their work. Attention must be given to better training for our residents via available curriculums and teaching modalities, as well as increased access to CME for OB/GYNs.

OBJECTIVE: To describe a stepwise approach to the laparoscopic excision of bladder endometriosis. DESIGN: Narrated surgical video. SETTING: Academic tertiary care hospital. PATIENT(S): Surgical footage was obtained from three patients who underwent surgery for bladder endometriosis. Institutional review board approval was not required in accordance with the Tri-Council Policy Statement of Canada, article 2.5. INTERVENTION(S): Laparoscopic excision of bladder endometriotic nodules by partial cystectomy. MAIN OUTCOME MEASURE(S): Overview of the relevant anatomy, disease overview, surgical planning and perioperative care, and the approach to the excision of bladder endometriotic nodules. RESULT(S): The approach to excision of bladder endometriotic nodules can be standardized in six reproducible steps: cystoscopy with or without ureteral stent placement; abdominal survey and treatment of posterior compartment disease; bladder mobilization; partial bladder cystectomy under cystoscopic guidance; cystotomy closure; and water-leak test. CONCLUSION(S): The safe and complete excision of bladder endometriosis relies on the understanding of surgical anatomy, the multidisciplinary aspect of patient care, and the standardization of the surgical approach.

OBJECTIVE: Evaluate the quality of information reported online about endometriosis and period pain. METHODS: An online search identified the top 20 websites for 4 search engines (Google, Ask, Bing, Yahoo). Videos, duplicates, and websites not containing information related to endometriosis and period pain were excluded. Three independent authors screened websites and systematically extracted data on website characteristics and on diagnosis and treatment mentions. Website accuracy and completeness were rated for a score out of 15. The Flesch readability ease score (FRES) was used to assess readability. RESULTS: Of 34 websites included, most were news related (44.1%) and health care affiliated (26.5%). Websites with affiliations had significantly higher accuracy scores than those without. Those with references had significantly higher completeness than those without. Non-news-related websites had significantly higher accuracy and completeness than news-related websites. The most commonly reported symptoms were dysmenorrhea (97.1% of websites), infertility (88.2%), and dyspareunia (82.4%). Cancer was mentioned on 41.1% of websites. Diagnostic laparoscopy (91.0%) and ultrasound (88.3%) were the most commonly mentioned diagnostic tools. Commonly reported therapeutics included the oral contraceptive pill (79.4%), laparoscopy (70.6%), non-steroidal anti-inflammatory drugs (NSAIDs; 67.6%), and gonadotropin-releasing hormone (GnRH) agonists (64.7%). Hysterectomy (59.0%) was mentioned more than progestins (53.0%). Overall, 18 of 34 websites (53%) contained 1 or more inaccurate or misleading statements. CONCLUSION: While most websites contained accurate statements, commonly reported misconceptions included an emphasized risk of cancer, lack of use/benefit of ultrasound for diagnosis, and a bias for surgical over medical management, where laparoscopy was mentioned more than first-line medications. This study highlights the importance of directing patients to evidence-based resources.
