Brief summary

Like endometriosis, adenomyosis is a benign uterine disorder and is histologically defined by presence of endometrial tissue in the myometrium (muscle layer) of the uterus. The prevalence of adenomyosis is difficult to determine, since histological confirmation is necessary following surgical biopsy or more commonly hysterectomy. For women wanting to retain their uterus, hysterectomy is not an option. Imaging technologies (e.g. transvaginal ultrasound and MRI), are used as a less invasive method of diagnosis and detection, although they have limitations. The Australian Endometriosis Clinicians Collaborative (AECC): adenomyosis substudy is a prospective longitudinal clinical study that will: 1. compare diagnosis and treatment of adenomyosis with regards to impact on pain, bleeding patterns, general health symptoms and quality of life using validated questionnaires 2. determine cost-effectiveness of diagnostic and treatment options 3. establish a national biobank of adenomyosis (and endometriosis) for future research capacity. Outcomes will determine optimised diagnosis and treatment pathways for clinicians that improve quality of life for women with adenomyosis.

Interventions

Current standard of care and management (e.g. hysterectomy) for patients with adenomyosis. Participants will be asked to complete online questionnaires at time of consent, related clinical care information (either from medical records or the clinician directly) will be entered onto the NECST Registry. Consenting participants will be followed up at 6-, 12-months and then annually post-enrolment for 5 years.
