Design: N/A

Setting: The patient was brought to the operating room and placed in dorsal lithotomy position.

Patients or Participants: This patient is a 35 year old who presented with pelvic pain, dyspareunia, and dyschezia secondary to endometriosis, seeking fertility-preservation surgery for treatment of endometriosis and bilateral ovarian endometriomas.

Interventions: The patient was scheduled for robotic-assisted endometriosis resection and CO2 fiber laser vaporization of ovarian endometriomas.

Measurements and Main Results: N/A

Conclusion: In conclusion, this video presents a case of CO2 laser vaporization for the surgical treatment of ovarian endometriomas. Increasing evidence suggests that the traditional approach of cystectomy negatively affects ovarian reserve. Vaporization techniques using CO2 and plasma energy may better preserve ovarian function, suggesting a viable alternative approach to the surgical treatment of ovarian endometriomas.
