Postoperative treatment of endometriosis — Hormonal suppression following surgical treatment of endometriosis has been found to decrease recurrence rates, but a beneficial effect on pain and pregnancy rates remains unproven. A randomized trial found that postoperative insertion of the levonorgestrel-releasing intrauterine device, compared with expectant management, resulted in decreased dysmenorrhea and pelvic pain at one-year follow-up [27]. (See "Overview of the treatment of endometriosis", section on 'Postoperative medical therapy'.)
