INTRODUCTION: Endometriosis is a heterogeneous pain condition with variable symptom expression. Abuse history has been associated with amplified pain, gastrointestinal symptoms, and central sensitization in varying populations; however, whe…

OBJECTIVE: To (1) determine how application of the updated international definition of deep endometriosis (DE) alters apparent disease prevalence across pelvic sites, and (2) characterize the distribution of endometriosis phenotypes, includ…

In this study, we evaluate a locally-deployed large-language model (LLM) to convert unstructured endometriosis transvaginal ultrasound (eTVUS) scan reports into structured data for imaging informatics workflows. Across 49 eTVUS reports, we …

OBJECTIVE: To explore diagnostic preferences among individuals with confirmed or suspected endometriosis to inform the development of patient-centred diagnostic strategies. DESIGN: Qualitative study using semi-structured focus group discus…

In this study, we evaluate locally deployed large language models (LLMs) for converting unstructured endometriosis transvaginal ultrasound (eTVUS) reports into structured data. Across 49 de-identified reports, we compared three on-premise L…

BACKGROUND: Endometriosis is a chronic disease characterized by endometrial-like tissue outside the uterus. Superficial endometriosis (SE) is the most prevalent form, yet it remains underdiagnosed due to subtle clinical and imaging presenta…

OBJECTIVE: To evaluate the diagnostic accuracy of transvaginal ultrasonography (TVUS) in detecting deep endometriosis, ovarian endometriosis, and superficial endometriosis using the IDEA (International Deep Endometriosis Analysis) consensus…

Objective: To assess the impact of complex disease states, including pouch of Douglas (POD) obliteration and deep endometriosis (DE) of the bowel, on the diagnostic accuracy of transvaginal ultrasound (TVUS) for detecting endometriosis of t…

ABSTRACT Objective: To explore diagnostic preferences among individuals with confirmed or suspected endometriosis to inform the development of patient-centered diagnostic strategies. Design: Qualitative study using semi-structured focus gro…

INTRODUCTION: Understanding what patients prioritize when seeking care for endometriosis and chronic pelvic pain (CPP) is crucial for delivering personalized, responsive care. However, patient-defined goals remain poorly characterized acros…

Abstract BACKGROUND Patients with endometriosis experience chronic, inflammatory symptoms including severe pelvic pain and infertility, caused by endometrial-like tissue growth outside the uterus. Endometriosis remains poorly understood, la…

Lay summary: Endometriosis is a chronic condition where tissue resembling the uterine lining grows elsewhere in the pelvis, often causing pain, infertility, and inflammation. For decades, textbooks and research papers have described the rec…

• High prevalence of severe dysmenorrhea in patients with PCOM. • Heavy menstrual flow strongly predicts severe dysmenorrhea. • Gravidity appears protective against severe menstrual pain. • PCOM identified in nearly 20% of gynecologic ultra…

Endometriosis is a prevalent gynecological disease, leading to chronic pain and inflammation, affecting 1 in 10 individuals presumed female at birth. The diagnostic journey is often arduous, marked by neglect of the right diagnosis and prol…

Transvaginal ultrasound (TVS) is crucial for diagnosing endometriosis, guided by the International Deep Endometriosis Analysis (IDEA) guidelines. While TVS excels in diagnosing ovarian (OE) and deep endometriosis (DE), superficial endometri…

Endometriosis affects 1 in 9 women and those assigned female at birth. However, it takes 6.4 years to diagnose using the conventional standard of laparoscopy. Noninvasive imaging enables a timelier diagnosis, reducing diagnostic delay as we…

OBJECTIVE: To determine the diagnostic test accuracy of transvaginal ultrasound (TVS) using a standardized technique for the diagnosis of deep endometriosis (DE) of the uterosacral ligaments (USLs) and adjacent torus uterinus (TU). METHODS…

The uterosacral ligaments (USLs) and torus uterinus (TU) are common sites for deep endometriosis (DE) but are challenging to diagnose through transvaginal ultrasound (TVS). Anatomical distortion caused by severe endometriosis, including pou…

An up-to-date description of ovarian and deep endometriosis distribution is necessary as the diagnostic algorithm now includes ultrasound as a highly specific diagnostic test. The primary objective was to describe ovarian/deep endometriosis…

The primary objective of this study is to establish whether ultrasound (US) diagnosis of endometriosis affects patient decision-making on treatment options. Secondary objectives include determining: 1) patient comfort of endometriosis US; 2…
