Abstract
Background
Deeply infiltrating endometriosis has an estimated prevalence of 1% in women of reproductive age. Ninety percent have rectovaginal lesions but disease may also include the bowel, bladder and ureters. Current practice often favours minimally invasive surgical excision; however, there is increasing evidence that medical management can be as effective as long as obstructive uropathy and bowel stenosis are excluded. Our objective was to establish the proportion of women with deeply infiltrating endometriosis successfully managed with hormonal therapies within our tertiary endometriosis centre in West London. Secondary analysis was performed on anonymised data from the Trust’s endometriosis database.
Results
One hundred fifty-two women with deeply infiltrating endometriosis were discussed at our endometriosis multidisciplinary meeting between January 2010 and December 2016. Seventy-five percent of women underwent a trial of medical management. Of these, 44.7% did not require any surgical intervention during the study period, and 7.9% were symptomatically content but required interventions to optimise their fertility prospects. Another 7.0% were successfully medically managed for at least 12 months, but ultimately required surgery as their symptoms deteriorated. 26.5% took combined oral contraceptives, 14.7% oral progestogens, 1.5% progestogen implant, 13.2% levonorgestrel intrauterine device, 22.1% gonadotrophin-releasing hormone analogues, and 22.1% had analogues for 3–6 months then stepped down to another hormonal contraceptive. All women who underwent serial imaging demonstrated improvement or stable disease on MRI or ultrasound.
Conclusions
Medical treatments are generally safe, well tolerated and inexpensive. More than half (52.6%) of women were successfully managed with medical therapy to control their symptoms. This study supports the growing evidence supporting hormonal therapies in the management of deeply infiltrating endometriosis. The findings may be used to counsel women on the likely success rate of medical management.
