What are the management options for endometriosis?

Management Options for Endometriosis

Hormonal therapies should be offered as first-line treatment for endometriosis, with combined oral contraceptives (COCs) and progestins being equally effective options for pain management in patients who do not desire immediate pregnancy. 1, 2

First-Line Treatment Options

Hormonal Therapies

• Combined Oral Contraceptives (COCs)

  • Preferably used in continuous regimen to provide consistent hormonal suppression
  • Standard starting dose: 30-35 μg ethinyl estradiol with levonorgestrel or norgestimate
  • Contraindications: severe uncontrolled hypertension, ongoing hepatic dysfunction, complicated valvular heart disease, migraines with aura, thromboembolism or thrombophilia, and complications of diabetes 1

• Progestins

  • Options include:
    • Norethindrone acetate
    • Depot medroxyprogesterone acetate (DMPA)
    • Dienogest
  • Effective for all endometriosis phenotypes for long-term treatment
  • Side effects may include amenorrhea (75% of patients on MPA), breakthrough bleeding, weight gain, and mood changes 1

Treatment Monitoring and Duration

• Evaluate treatment response after 3-6 months
• Long-term therapy is often necessary as 25-34% of patients experience recurrent pelvic pain within 12 months of discontinuing hormonal treatment 1, 2
• Approximately one-third of women demonstrate resistance to progestin therapy, requiring alternative treatments 1

Second-Line Treatment Options

Surgical Interventions

• Laparoscopic removal of endometriotic lesions
  • Consider when hormonal therapies are ineffective or contraindicated
  • Provides significant pain reduction during first six months
  • Up to 44% of women experience symptom recurrence within one year 1, 2
  • Excision of endometriosis is preferred over ablation or fulguration 3

Advanced Hormonal Therapies

• GnRH agonists and antagonists (second-line)

  • Effective for pain relief but may cause bone mineral loss
  • Should be used with add-back therapy to prevent side effects 1, 2

• Aromatase inhibitors (third-line) 2

Treatment for Severe or Refractory Cases

Definitive Surgical Options

• Hysterectomy with removal of endometriotic lesions
  • Consider for patients who have completed childbearing and have severe symptoms unresponsive to other treatments
  • Approximately 25% of patients experience recurrent pelvic pain after hysterectomy
  • 10% require additional surgery 1, 2

Special Considerations

Fertility Concerns

• For patients desiring pregnancy, timing of treatment is critical as progestins inhibit ovulation during active treatment 1
• For fertility-preserving therapy, medroxyprogesterone acetate (MPA) or megestrol acetate (MA) is recommended 1

Holistic and Adjunctive Approaches

• Nutritional interventions

  • Gluten-free, low-nickel, and high omega-3 diets may improve endometriosis-related pelvic pain
  • Low FODMAP and plant-based diets can help, especially with concurrent IBS 4

• Mind-body therapies

  • Cognitive behavioral therapy (CBT) beneficial for postoperative pain reduction
  • Mindfulness, progressive muscle relaxation, and yoga may improve pain and quality of life 4

• Other adjunctive therapies

  • Acupuncture and moxibustion may improve pain scores
  • Transcutaneous electrical nerve stimulation (TENS) can improve deep dyspareunia 4

Common Pitfalls to Avoid

• Delaying treatment escalation when first-line therapies fail
• Using GnRH agonists without add-back therapy
• Discontinuing hormonal therapy too early
• Using progestins alone in women who have undergone oophorectomy 1
• Failing to recognize that endometriosis is a multisystem disease requiring a multimodal approach 5

Management Algorithm

1. Start with hormonal therapy (COCs or progestins) for patients not seeking immediate pregnancy
2. Evaluate response after 3-6 months
3. If inadequate response, consider:
   • Alternative hormonal therapy
   • Surgical removal of lesions
4. For persistent symptoms despite surgery and hormonal therapy, consider:
   • Second-line hormonal options (GnRH agonists/antagonists)
   • Third-line options (aromatase inhibitors)
   • Definitive surgery (hysterectomy) for those who have completed childbearing
5. Incorporate adjunctive and holistic approaches throughout treatment course
