This video demonstrates Ovarian Endometrioma Ablation for Preservation of the Ovarian Parenchyma. When compared with plasma energy ablation, cystectomy is responsible for a statistically significant decrease in ovarian volume and a statistically significant reduction in AFC. This data should be taken into account in therapeutic decision-making concerning women attempting pregnancy, especially where there are other risk factors for postoperative ovarian failure.

Endometriotic Ablation is a procedure that destroys tissue. This process destroys the tissue of the uterus that grows outside the uterus.

Small cuts are made in the belly. The belly is filled with air to make more space for the doctor to work. Small tubes with tools are placed through the cuts. One tube has a camera that sends images to a screen in the room. The doctor will use it to check the area and remove patches. A laser, electric current, gas, or another method will be used to burn off the patches.

Ovarian endometrioma, commonly referred to as a “chocolate cyst,” is a frequent manifestation of endometriosis and is often associated with chronic pelvic pain, dysmenorrhea, dyspareunia, and infertility. Surgical management aims not only to relieve symptoms and reduce recurrence but also to preserve ovarian reserve, particularly in women of reproductive age. Ovarian endometrioma ablation has emerged as a tissue-sparing alternative to cystectomy, focusing on the preservation of healthy ovarian parenchyma while effectively treating the disease.

Rationale for Ovarian Parenchymal Preservation

The ovarian cortex contains primordial follicles that are essential for reproductive potential. Traditional cystectomy, though effective in reducing recurrence, may inadvertently remove or damage healthy ovarian tissue, leading to a decline in ovarian reserve. This is reflected by reduced anti-Müllerian hormone (AMH) levels and impaired ovarian response. Ablative techniques aim to destroy the endometriotic lining while minimizing trauma to the surrounding ovarian tissue, thereby maintaining hormonal function and fertility.

Indications for Endometrioma Ablation

Ovarian endometrioma ablation is particularly indicated in:

Young women desiring future fertility

Patients with bilateral endometriomas

Recurrent endometriomas after previous surgery

Small to moderate-sized cysts (generally ≤4–5 cm)

Women with reduced ovarian reserve

Careful patient selection is essential to achieve optimal outcomes.

Surgical Technique

The procedure is typically performed via laparoscopy, ensuring minimal invasiveness and enhanced visualization.

Key Steps Include:

Ovarian Exposure and Assessment: Gentle handling of the ovary to avoid unnecessary trauma.

Cyst Drainage: Aspiration of the cyst contents followed by irrigation to clearly identify the cyst wall.

Identification of the Endometriotic Lining: Differentiation between the cyst capsule and healthy ovarian tissue.

Ablation of the Cyst Wall: Controlled destruction of the endometriotic epithelium using bipolar coagulation, plasma energy, or laser (CO₂ or diode laser).

Hemostasis: Achieved with minimal thermal spread to preserve surrounding ovarian tissue.

The goal is to ablate the pathological tissue completely while maintaining the integrity of the ovarian cortex.

Ablation Modalities

Several energy sources are used for ovarian endometrioma ablation:

Bipolar Electrocoagulation: Widely available but requires cautious use to avoid thermal damage.

Plasma Energy: Offers precise tissue destruction with minimal penetration.

Laser Ablation: Provides controlled depth of penetration and superior tissue preservation.

Among these, laser and plasma energy techniques are increasingly favored for their parenchyma-sparing properties.

Advantages of Ablation Over Cystectomy

Better preservation of ovarian reserve

Reduced risk of inadvertent follicular loss

Lower postoperative decline in AMH levels

Suitable for recurrent and bilateral disease

Shorter operative time in selected cases

Limitations and Recurrence

While ablation is ovarian-sparing, it may carry a slightly higher risk of recurrence compared to complete cyst excision. Therefore, meticulous technique and postoperative medical management, such as hormonal suppression, are crucial to minimize recurrence rates.

Postoperative Management

Postoperative care includes:

Hormonal therapy (e.g., oral contraceptives or progestins) to suppress recurrence

Pain management and early mobilization

Fertility planning and follow-up evaluation of ovarian reserve

Regular follow-up with ultrasonography and clinical assessment is recommended.

Conclusion

Ovarian endometrioma ablation represents an effective, fertility-preserving surgical strategy that balances disease control with protection of ovarian function. When performed by experienced laparoscopic surgeons and in appropriately selected patients, ablation offers excellent symptomatic relief while safeguarding ovarian parenchyma and reproductive potential. As surgical technologies advance, parenchyma-sparing approaches are likely to play an increasingly important role in the management of endometriosis.
