Comparing the treatment of endometriosis-related pain by excision of endometriosis or hysterectomy: A multicentre prospective cohort study.

Patients who undergo endometriosis excision plus hysterectomy experience greater improvement in pain and quality of life compared to those who have endometriosis excision alone. There are additional benefits of bilateral oophorectomy with hysterectomy, although its value is less clear due to loss of follow-up.
