In a woman with extensive adenomyosis, multiple intramural fibroids, lower abdominal wall endometriosis, who has failed levonorgestrel intrauterine system (LNG‑IUS) and two months of dienogest and continues to have heavy bleeding through day 25, what are the recommended next management steps?

Management of Extensive Adenomyosis with Multiple Fibroids and Abdominal Wall Endometriosis After Failed Medical Therapy

Given the failure of both LNG-IUS and dienogest with persistent heavy bleeding through day 25, and the presence of extensive adenomyosis with multiple intramural fibroids and abdominal wall endometriosis, hysterectomy is the definitive treatment that should be strongly considered, as it provides complete resolution of all symptoms and eliminates the risk of recurrence. 1

Primary Surgical Consideration: Hysterectomy

Hysterectomy remains the most appropriate definitive treatment for this complex presentation, particularly given:

• Treatment failure of both first-line (LNG-IUS) and second-line (dienogest) medical therapies 2, 3
• Extensive adenomyosis with concomitant multiple intramural fibroids, which significantly reduces the likelihood of symptom relief from uterus-preserving procedures 1
• Persistent heavy bleeding despite 2 months of dienogest, indicating inadequate response to hormonal suppression 4, 5

Key Points About Hysterectomy in This Context

• Hysterectomy provides definitive resolution of all fibroid-related and adenomyosis-related symptoms and allows simultaneous treatment of the adenomyosis, fibroids, and potentially the abdominal wall endometriosis if excised during the same procedure 1
• The least invasive route should be selected: vaginal or laparoscopic approaches are associated with shorter hospital stays, faster recovery, and lower infection rates compared to abdominal hysterectomy 1
• Ovarian conservation is recommended (assuming no other indication for removal) to avoid precipitating menopause and associated cardiovascular risks 1

Important Caveats About Hysterectomy

• Even with ovarian conservation, hysterectomy carries risks including elevated cardiovascular disease risk, mood disorders, and some studies report increased mortality especially when performed at young age 1
• Short-term complications include venous thromboembolism, ureter/bowel/bladder injury, bleeding requiring transfusion, and vaginal cuff complications 1

Alternative Uterus-Preserving Options (If Fertility Desired or Patient Declines Hysterectomy)

Uterine Artery Embolization (UAE)

UAE is the most appropriate uterus-preserving intervention for this presentation, given the extensive disease burden:

• Effective for both adenomyosis and fibroids simultaneously 1, 6
• Causes persistent decreases in pain and heavy menstrual bleeding with average fibroid size reduction >50% at 5 years 1
• Lower complication rates compared to hysterectomy with similar symptom relief in randomized trials 1
• Reintervention rates: 28% at 5 years and 35% at 10 years in long-term follow-up 1

Why Other Uterus-Preserving Options Are Less Suitable

Myomectomy (laparoscopic or open) is NOT recommended in this case because:

• Patients with significant intramural fibroid burden AND concomitant adenomyosis are less likely to experience symptom relief from myomectomy 1
• Myomectomy does not address the extensive adenomyosis, which is likely the primary driver of heavy bleeding 1

Hysteroscopic myomectomy is NOT applicable as the fibroids are intramural (not submucosal), and this approach would not address the adenomyosis 1

MR-guided focused ultrasound (MRgFUS) could be considered but:

• Limited data for extensive adenomyosis with multiple fibroids 1
• Reintervention rates range from 13-30% at 2 years 1
• May require multiple treatment sessions given the extensive disease burden 1

Management of Abdominal Wall Endometriosis

The abdominal wall endometriosis should be addressed separately or concurrently:

• Percutaneous thermal ablation (such as cryoablation) is effective for extraperitoneal abdominal wall endometriosis 6
• Surgical excision can be performed at the time of hysterectomy if that route is chosen 1
• This lesion will not respond to UAE and requires separate intervention 6

Additional Medical Options (If Surgery Declined or Delayed)

If the patient refuses surgical intervention or needs temporizing therapy:

• GnRH antagonists (elagolix, relugolix) with add-back therapy are second-line medical options that reduce bleeding and tumor volume 1, 7
• GnRH agonists (leuprolide) can be used short-term but are associated with hypoestrogenic effects 1, 8
• However, given the failure of LNG-IUS and dienogest, further medical therapy is unlikely to provide adequate symptom control 2, 4

Critical Decision Points

The key factors determining the optimal approach are:

1. Desire for future fertility: If yes, UAE is the best option; if no, hysterectomy is definitive 1
2. Severity of symptoms and impact on quality of life: Persistent bleeding through day 25 despite medical therapy indicates severe disease requiring definitive intervention 4, 5
3. Patient preference regarding uterine preservation: This must be explicitly discussed 1

Common pitfall to avoid: Do not pursue additional medical therapy or limited surgical procedures (like myomectomy alone) in patients with extensive adenomyosis and multiple intramural fibroids, as treatment failure rates are high 1, 4
