Is this trial a fit for you?

Likely a good fit

Ideal candidates are people who received HIFU for rectal endometriosis in study HIFU/F/13.12, HIFU/F/20.01 (ENDO HIFU R1), or HIFU/F/21.12 (ENDO HIFU R2), agree to participate, and have internet access to complete electronic questionnaires.

Probably not a fit

Patients who were not treated with HIFU in the listed prior studies, who cannot complete electronic questionnaires, or who are under guardianship or deprived of liberty are not eligible and therefore will not receive benefit from this follow-up.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational follow-up collects long-term outcome data from patients previously treated with HIFU for rectal endometriosis in the named earlier HIFU studies. Participants complete an electronic questionnaire and receive a telephone call to report symptoms and other health parameters. No new procedures are performed; the study relies on patient-reported outcomes and phone monitoring. The goal is to describe durability of symptom change and any late effects after HIFU treatment.

Why it matters

Potential benefit: If successful, the study could show that HIFU provides durable symptom relief and lower recurrence for rectal endometriosis patients treated with this technique.

How similar studies have gone: HIFU has shown promise in small and early studies for pelvic indications, but long-term data specifically for rectal endometriosis remain limited.
