Endometriosis: A Review

Area of Science:

• Gynecology
• Reproductive Endocrinology
• Surgical Innovation

Background:

• Endometriosis is a chronic, estrogen-dependent inflammatory condition affecting up to 10% of reproductive-age women globally.
• Characterized by endometrial-like tissue outside the uterus, it frequently causes pelvic pain (90%) and infertility (26%).
• Diagnosis is often delayed, averaging 5-12 years, despite symptoms like dysmenorrhea, nonmenstrual pelvic pain, and dyspareunia.

Purpose of the Study:

• To review the current understanding of endometriosis, including its clinical presentation, risk factors, and diagnostic challenges.
• To evaluate the effectiveness of various treatment modalities, from first-line hormonal therapies to surgical interventions.
• To highlight the persistent challenges in managing endometriosis, particularly recurrent pain after treatment.

Main Methods:

• A comprehensive review of existing literature on endometriosis was conducted.
• Clinical presentations, risk factors, diagnostic methods (symptoms, imaging, surgery), and treatment outcomes were analyzed.
• A network meta-analysis of hormonal treatments was considered for pain reduction efficacy.

Main Results:

• Hormonal treatments (oral contraceptives, progestins, GnRH agonists) show significant pain reduction compared to placebo, with minimal differences among options.
• However, 11-19% experience no pain relief, and 25-34% have recurrent pain within a year of discontinuing hormonal therapy.
• Surgical lesion removal and hysterectomy are considered for refractory cases, but recurrence rates remain significant (25% pain recurrence post-hysterectomy).

Conclusions:

• Endometriosis significantly impacts women's quality of life, necessitating effective and sustained management.
• First-line hormonal therapies offer pain relief for many, but a substantial proportion require alternative or adjunctive treatments.
• Recurrent pain after various interventions underscores the chronic nature of endometriosis and the need for long-term patient care strategies.
