STUDY QUESTION: Is there an association between the somatic loss of PTEN (phosphatase and tensin homolog) and ARID1A (AT-rich interaction domain 1A) and endometriosis disease severity and worse clinical outcomes? SUMMARY ANSWER: Somatic PT…

OBJECTIVE: The World Endometriosis Research Foundation established the Endometriosis Phenome and Biobanking Harmonisation Project (EPHect) to create standardized documentation tools (with common data elements) to facilitate the comparison a…

BACKGROUND: Approximately half of people with endometriosis experience deep dyspareunia; however, there is no means of objective self-testing of endometriosis-associated deep dyspareunia. AIM: The aim of this study was to assess the accept…

Endometriosis-associated dyspareunia can persist after surgical interventions, requiring multidisciplinary treatment including pain education. This study explored the effectiveness of a one-day workshop for improving knowledge, behavioural …

IMPORTANCE: A subset of people who undergo surgery for endometriosis have persistent pain, suggesting that other factors besides the endometriosis, such as central sensitization, may play a role in this pain. The Central Sensitization Inven…

[For a first-person account of endometriosis, see www.cmaj.ca/lookup/doi/10.1503/cmaj.230215][1] KEY POINTS Endometriosis is a chronic condition defined by the presence of endometrial-like tissue outside of the uterus, which can lead to est…

Dysmenorrhea is the most common gynecologic condition among the female population and has a significant impact on life course potential. It has a widespread impact on a female's mental and physical well-being, with longstanding impairments …

The clinical phenotype of somatic mutations in endometriosis is unknown. The objective was to determine whether somatic KRAS mutations were associated with greater disease burden in endometriosis (i.e. more severe subtypes and higher stage)…

BACKGROUND: After endometriosis surgery, pain can persist or recur in a subset of patients. A possible reason for persistent pain after surgery is central nervous system sensitization and associated pelvic pain comorbidities. Surgery addres…

BACKGROUND: Endometriosis is a complex chronic disease characterized by pain, including painful sex, that can contribute to considerable sexual function, self-esteem, and relationship challenges. Digital storytelling is an arts-based, parti…

Endometriosis is a chronic, debilitating, gynecologic condition with a non-specific clinical presentation. Globally, patients can experience diagnostic delays of ~6 to 12 years, which significantly hinders adequate management and places a s…

Endometriosis is a chronic gynecological disorder that affects approximately 10% of women of reproductive age. Most medical treatments used today for endometriosis pain are hormonal therapies, which are not an option for those trying to con…

BACKGROUND: More research is needed that compares the outcomes between those who underwent a hysterectomy for endometriosis with conservation of one or both ovaries and those who underwent a hysterectomy with bilateral salpingo-oophorectomy…

Abstract Background We recognized a paucity of accessible, evidence-based, empowering patient-centred resources for those with endometriosis-associated dyspareunia. We aimed to develop a patient-centred educational website for those affec…

BACKGROUND Endometriosis is a complex chronic disease characterized by pain, including painful sex, that can contribute to considerable sexual function, self-esteem, and relationship challenges. Digital storytelling is an arts-based, parti…

A key clinical problem is identifying the patient with endometriosis whose pain is complicated by central nervous system sensitization, where conventional gynecologic treatment (eg, hormonal therapy or surgery) may not completely alleviate …

Imbalances in gut and reproductive tract microbiota composition, known as dysbiosis, disrupt normal immune function, leading to the elevation of proinflammatory cytokines, compromised immunosurveillance and altered immune cell profiles, all…

STUDY OBJECTIVE: Endometriosis fertility index (EFI) is a robust tool to predict the pregnancy rate in patients with endometriosis who are attempting non-in vitro fertilization conception. However, EFI calculation requires laparoscopy. Newl…

STUDY OBJECTIVE: The objective of our study was to provide a contemporary description of hysterectomy practice and temporal trends in Canada. DESIGN: A national whole-population retrospective analysis of data from the Canadian Institute fo…

OBJECTIVE: To characterize fellowship training experiences in the 11 Canadian minimally invasive gynaecologic surgery (MIGS) programs and compare the surgical exposure of fellows in these programs to that of the American Association of Gyne…
