CO2 laser fiber vaporization of ovarian endometriomas increased antral follicle count, especially in younger patients, without significantly altering anti-Müllerian hormone levels, suggesting potential preservation of ovarian function.

Abstract

Background In recent years, excisional surgery has been questioned as an ideal surgical approach for endometriomas because it is associated with potential removal of healthy ovarian tissue and loss of ovarian follicles with subsequent reduction of ovarian reserve. The aim of our study was to evaluate the benefits of CO 2 laser vaporization through a clinical trial assessing the postoperative changes in ovarian reserve as indicated by antral follicle count (AFC) and anti-Müllerian hormone (AMH). Materials and Methods Fifteen patients undergoing surgery for primary unilateral or bilateral symptomatic endometriomas were enrolled in the study. During surgery, the cystic lining was completely vaporized with CO 2 laser fiber (AcuPulse Duo system, Lumenis); before surgery and at 1 and 3 months after surgery, ovarian reserve was evaluated by pelvic ultrasound to determine the AFC, and blood sample to determine AMH levels. Results The AFC of the operated ovary was significantly increased after treatment at 1 and 3 months' follow-up (p = 0.0021; p = 0.005, respectively); the increase is particularly significant in women younger than 35 years (p = 0.012). No statistically significant changes were reported in serum AMH concentrations at 1 or 3 months' follow-up. No recurrences of symptoms and no recurrences of endometrioma were reported. Conclusions These data support the hypothesis that endometrioma vaporization with CO 2 laser fiber may be a valid method to preserve ovarian function; however, further studies are required before advocating the routine use of CO 2 laser vaporization for the management of ovarian endometriosis.
