What non‑hormonal treatment options are recommended for a patient with endometriosis who refuses hormonal therapy?

Non-Hormonal Treatment for Endometriosis

For patients refusing hormonal therapy, NSAIDs should be the primary medical treatment for immediate pain relief, with surgery being the definitive option when medical management fails or for severe disease. 1, 2

First-Line Non-Hormonal Medical Management

NSAIDs are the cornerstone of non-hormonal pain management for endometriosis:

• Start with naproxen 550 mg twice daily or ibuprofen 600-800 mg three times daily for immediate pain relief 2, 3
• NSAIDs should be used at appropriate doses and schedules as adjunctive therapy 4
• These medications work by reducing prostaglandin production from endometriotic lesions, which is a primary driver of pain 5

Important limitation: 11-19% of patients with endometriosis experience no pain reduction with any medical treatment, and NSAIDs alone rarely provide complete symptom control 6

Surgical Management

Surgery is the definitive non-hormonal treatment and should be strongly considered when NSAIDs are insufficient:

• Laparoscopic excision by an endometriosis specialist provides significant pain reduction during the first 6 months after surgery 1, 3
• Complete surgical excision of all visible endometriotic lesions is the gold standard approach 3
• Surgery is particularly indicated for severe endometriosis, deep infiltrating disease, or when medical treatment is ineffective or contraindicated 2, 3

Critical caveat: Up to 44% of women experience symptom recurrence within one year after surgery, highlighting that surgery is not always curative 1, 2, 3

Preoperative Imaging

Before proceeding to surgery, obtain high-quality imaging:

• Pelvic MRI is recommended to map disease extent, identify deep infiltrating lesions, and plan the surgical approach 2
• Transvaginal ultrasound is an acceptable alternative or complementary modality 2
• Preoperative imaging reduces morbidity and mortality by decreasing incomplete surgeries and the need for repeat procedures 2, 3

Surgical Classification and Planning

During surgery, complete multiple classifications:

• r-ASRM staging for general classification 3
• Enzian classification if deep endometriosis is present 3
• Endometriosis Fertility Index (EFI) if fertility is a concern, as this validated tool predicts fertility outcomes and guides treatment planning 3

Hysterectomy Considerations

For patients with completed childbearing who fail conservative treatments:

• Hysterectomy with bilateral salpingo-oophorectomy and removal of all visible endometriotic lesions may be considered 2, 6
• This is the most definitive surgical approach for appropriate candidates 2

Major pitfall: Approximately 25% of patients who undergo hysterectomy for endometriosis experience recurrent pelvic pain, and 10% require additional surgery 6

Non-Medical Adjunctive Strategies

Emerging evidence supports complementary approaches:

• Dietary modifications, exercise, and self-management strategies are increasingly recognized as part of a multimodal approach 7, 8
• These should supplement, not replace, primary treatment with NSAIDs or surgery 9, 8

Critical Clinical Pitfalls to Avoid

• No medical therapy completely eradicates endometriotic lesions—NSAIDs only provide symptomatic relief without addressing the underlying disease 1, 3
• Pain severity correlates poorly with laparoscopic appearance but correlates with the depth of lesions, not the type of lesions seen 1, 3
• Diagnostic delay averages 5-12 years after symptom onset, with most women consulting 3 or more clinicians before diagnosis 6
• Normal physical examination and imaging do not exclude endometriosis—definitive diagnosis requires surgical visualization 6

Treatment Algorithm for Non-Hormonal Management

1. Initiate NSAIDs at therapeutic doses (naproxen 550 mg BID or ibuprofen 600-800 mg TID) 2, 3
2. If NSAIDs provide inadequate relief within 3 months, proceed to surgical evaluation 2
3. Obtain preoperative pelvic MRI to map disease extent 2, 3
4. Refer to endometriosis specialist for laparoscopic excision of all visible lesions 3
5. If symptoms recur after surgery, consider repeat surgery or discuss hormonal options despite initial refusal 1, 6
6. For refractory cases with completed childbearing, hysterectomy with bilateral salpingo-oophorectomy may be offered 2, 6
