From the Research
The most effective management option for endometriomas is a personalized approach that considers the patient's symptoms, fertility desires, and endometrioma characteristics, with laparoscopic excision being the preferred surgical method for symptomatic patients or those with large endometriomas, as supported by the most recent study 2. Management options for endometriomas include both medical and surgical approaches. Medical management typically involves hormonal suppression with combined oral contraceptives, progestins, or GnRH agonists, which can reduce pain and potentially slow endometrioma growth.
- Key considerations for management include:
- Patient symptoms: severity and impact on quality of life
- Fertility desires: immediate pregnancy plans or future fertility goals
- Endometrioma characteristics: size, location, and presence of adhesions
- Surgical management, specifically laparoscopic excision (cystectomy), is preferred over drainage and ablation for its benefits in pain relief, lower recurrence rates, and improved fertility outcomes, as noted in 2 and 3.
- However, surgery carries risks, such as diminishing ovarian reserve, especially with repeated procedures or bilateral endometriomas, highlighting the need for careful patient selection and surgical technique, as discussed in 4 and 5.
- The decision between medical and surgical approaches should be individualized, considering factors such as patient age, symptom severity, cyst size, fertility plans, and previous treatment responses, with the goal of optimizing outcomes while minimizing risks, as emphasized in 2 and 5.
