Brief Summary:

Background: Endometriosis is a disease affecting 8-15 % of fertile women and is a cause of abdominal pain and suffering during women's menstrual periods. A subgroup of patients with DIE has an infiltration into the rectosigmoid bowel wall (4-37%). Knowledge of the growth pattern of rectosigmoid lesions related to subjective symptoms is mandatory in order to assess the need for follow-up with transvaginal ultrasound during medical treatment.


Symptoms will follow growth of rectosigmoid endometriosis.

Material and methods:

Two different cohorts of women, based on time of diagnosis of rectosigmoid endometriosis and treatment with hormonal intrauterine device or continuous oral contraceptives will receive a questionnaire and a transvaginal ultrasound scan (measuring size and volume) at inclusion, (6) and 12 months later.


Patients treated conservatively may be followed by questionnaires, thereby reducing the need for time consuming clinical controls.
