Aspiration of ovarian endometriomas yields high recurrence, while laparoscopic cystectomy offers prolonged symptom relief, lower recurrence, and higher pregnancy rates compared to ablation or aspiration alone.

This paper reviews controversies in the surgical management of ovarian endometriomas, focusing on hormonal suppression, aspiration, laparoscopic fenestration/ablation, and laparoscopic cyst wall stripping, including implications for ovarian function and fertility. It reports that hormonal suppression for ovarian endometriomas larger than 1 cm is not effective for the lesion itself, though symptoms may improve in about 40% to 65% for 6–12 months; transvaginal or transabdominal guided aspiration is not recommended as first-line surgery due to high recurrence (28% to 100% within 1–9 months), and adding hormonal suppression before or after aspiration does not change outcomes. Laparoscopic fenestration and ablation of the cyst wall (laser or electrocautery) is described as better than aspiration alone, with symptomatic improvement rates of 74–91%, recurrence 8–13%, and pregnancy 45–50%, while laparoscopic stripping of the cyst wall appears associated with more prolonged symptom improvement and lower pelvic pain recurrence and reoperation rates, despite being technically more demanding. The paper concludes current studies indicate internal wall vaporization does not impair IVF performance, that cystectomy carries theoretical risk of viable ovarian tissue loss that can be mitigated with microsurgical technique preserving the residual cortex, and that IVF outcomes after endometrioma removal/destruction are similar to those in tubal-factor or idiopathic infertility. This paper is centrally about endometriosis — it specifically addresses the surgical management of ovarian endometriomas and related fertility and recurrence outcomes.

Abstract

La supresión hormonal del endometrioma ovárico mayor de 1 cm no es efectiva; sin embargo, tal supresión puede mejorar los síntomas en el 40% a 65% de los pacientes por un período de 6 a 12 meses. La aspiración de endometrioma ya sea transvaginal o transabdominal mediante la guía ultrasonográfica o por laparoscopía no es aconsejable como tratamiento quirúrgico de primera línea. Estos procedimientos están seguidos de una alta tasa de recurrencia (28% a 100%) dentro de 1 a 9 meses siguientes a la aspiración. La supresión hormonal antes o después de la aspiración no afecta el resultado. La vaporización laparoscópica de las paredes del quiste previa apertura de éste ya sea con láser o electrocauterio es mejor que el tratamiento de aspiración solo. La tasa de mejoría de los síntomas después del procedimiento es de 74% a 91%, la tasa de recurrencia es de 8% a 13% con una tasa de embarazo del 45% al 50%. El tratamiento laparoscópico del endometrioma ovárico por extirpación de la pared del quiste parece ser el mejor tratamiento quirúrgico. Este procedimiento es técnicamente más difícil que la vaporización de la pared del quiste, pero se asocia con una mejoría prolongada de la sintomatología, baja recurrencia del dolor pélvico, y bajas tasas de reoperación. Las tasas acumulativas de embarazo son más altas que después de vaporización. Los estudios actuales concluyen primero, que la vaporización de la pared interna del endometrioma no daña la función ovárica en términos de los parámetros de FIV y resultados; segundo, que los riesgos teóricos de pérdida de tejido ovárico viable durante la cistectomía existen pero se puede evitar con una técnica microquirúrgica laparoscópica, teniendo el cuidado de preservar la corteza ovárica residual normal; y tercero, los resultados de FIV después de extirpar o destruir los endometriomas en los pacientes con endometriosis son similares cuando se comparan con mujeres con factor tubárico o infertilidad idiopática.The hormonal suppression of ovarian endometriomas larger than 1 cm is not effective; however, such suppression may improve the symptoms in 40% to 65% of the patients for a period of 6 to 12 months. Aspiration of endometriomas either by transvaginal or transabdominal ultrasound guidance or laparoscopy is no advisable as a first-line surgical treatment. These procedures are followed by a high recurrence rate (28% to 100%) within 1 to 9 months following the aspiration. Hormonal suppression before or after the aspiration does not affect the result. Laparoscopic fenestration and ablation of the endometriotic cyst wall either by laser or electrocautery is a better treatment than aspiration alone. This procedure can be done in a simple setting, eliminating the need for another operation. The symptomatic improvement rate after this procedure is 74% to 91%, the recurrence rate is 8% to 13%, and the pregnancy rate is 45% to 50%. Laparoscopic treatment of ovarian endometrioma by stripping the cyst wall from the remaining ovarian tissue seems to be the best surgical treatment. This procedure is technically more demanding than fenestration, but is associated with prolonged symptomatic improvement, a lower recurrence of pelvic pain, and a lower reoperation rate. The cumulative pregnancy rate is also higher than after fenestration only. The current studies conclude, first, that vaporization of the internal cyst wall does not impair ovarian function in terms of IVF parameters and outcome; second, that theoretical risks of loss of viable ovarian tissue during cystectomy exist but may be avoided by microsurgical laparoscopic technique, taking care to preserve the normal residual ovarian cortex; and, third that, after removal or destruction of endometriomas, IVF outcomes are similar in endometriosis patients when compared to women with tubal factor or idiopathic infertility.
