What is the best treatment for adenomyosis in a symptomatic woman who does not wish to preserve fertility?

Best Treatment for Adenomyosis (No Fertility Preservation Desired)

For symptomatic women with adenomyosis who do not wish to preserve fertility, hysterectomy remains the definitive treatment providing complete symptom resolution, though uterine artery embolization (UAE) should be strongly considered as a first-line uterus-sparing alternative given its favorable safety profile and comparable symptom control to hysterectomy. 1

Treatment Algorithm

First-Line Options (in order of preference):

1. Uterine Artery Embolization (UAE)

• Primary recommendation for patients desiring uterus preservation 2
• Long-term symptomatic relief ranges from 65-88% at 24-65 months follow-up 2
• Recent prospective data shows 83% achieve complete adenomyosis necrosis with significant symptom relief 2
• Critical advantage over hysterectomy: Randomized trials demonstrate similar symptom relief but with decreased severe complications, shorter hospitalization, and faster return to activities 1
• Recurrence rates: 40-50% at 2 years, though more recent studies show better durability 2
• Works well for both pure adenomyosis and adenomyosis with coexistent fibroids 1

2. Hysterectomy (Definitive Treatment)

• Only when UAE fails or patient specifically requests definitive surgery 1
• Provides 100% resolution of adenomyosis symptoms
• Important caveats: Even with ovarian preservation, hysterectomy carries increased risks of:
  • Cardiovascular disease 1
  • Osteoporosis and bone fractures 1
  • Dementia 1
  • Mood disorders 1
  • Increased mortality when performed at young age 1
• If hysterectomy chosen, use least invasive route: Vaginal > Laparoscopic > Abdominal 1

Medical Management (Temporizing Only)

Use when patient declines procedures or as bridge therapy:

• Levonorgestrel-releasing IUD (LNG-IUS): Most effective medical option 1
  • Demonstrated superior to combined oral contraceptives in randomized trials 1
  • Local mechanism reduces systemic hormone exposure
  • Long duration of action
• GnRH antagonists: Effective for symptom control but only short-term use 1
• Dienogest or continuous oral contraceptives: Secondary options 3, 4

Critical limitation: Medical therapies only temporize symptoms and do not treat bulk symptoms 1

Options NOT Recommended

Myomectomy alone: Ineffective for adenomyosis as it does not address the diffuse myometrial disease 1

Endometrial ablation: Associated with high failure rates in presence of adenomyosis 1

MR-guided focused ultrasound (MRgFUS): Insufficient evidence specifically for adenomyosis treatment 1

Key Decision Points

Choose UAE over hysterectomy when:

• Patient desires uterus preservation
• Patient is younger (to avoid long-term cardiovascular/cognitive risks of hysterectomy)
• Patient wants faster recovery and return to activities
• Symptoms are primarily bleeding and pain

Choose hysterectomy when:

• UAE has failed
• Patient has concurrent conditions requiring hysterectomy (high-grade cervical dysplasia, uterine prolapse, endometrial pathology)
• Patient specifically requests definitive treatment
• Concomitant severe endometriosis requiring surgical management 2

Common Pitfalls

1. Assuming hysterectomy is automatically superior: The 2024 ACR guidelines explicitly state hysterectomy should be avoided if less invasive procedures are available, given the increased complication rates 1

2. Overlooking UAE durability concerns: While older data showed 40-50% recurrence at 2 years, more recent studies (2018 guidelines) demonstrate 73-88% symptom control at longer follow-up 2

3. Using myomectomy for adenomyosis: This addresses fibroids but not the diffuse adenomyotic tissue 1

4. Relying solely on medical management: These are temporizing measures that don't address bulk symptoms and require indefinite use 1
