Endometriosis: papel del láser de CO2 en el abordaje quirúrgico

The surgical treatment of choice for endometrioma is cystectomy or endometrioma decapsulation. However, there is sufficient scientific evidence showing that this technique is associated with a decrease in ovarian reserve, either due to the removal of healthy ovarian tissue during the procedure or due to thermal damage performed during the control of haemostasis. For this reason, new surgical approaches have been described to alleviate this negative effect on ovarian reserve. The use of the CO₂ laser in gynecology has been known since the 1980s, and vaporization of the endometrioma capsule using this laser is a simple, easy-to-use, easily reproducible, and technically accessible technique. Although it was initially thought that the recurrence rate with this technique was higher, several studies show the opposite. Likewise, the damage to the ovarian reserve is less compared to decapsulation, in terms of better follicular count and antimullerian hormone level. Although the rates of spontaneous pregnancy and assisted reproductive techniques are similar, in assisted reproductive techniques patients treated with CO₂ laser vaporization have a higher follicular count and antimullerian hormone level compared to patients treated with decapsulation. To this day, the treatment of endometrioma continues to be a matter of discussion. However, the studies reviewed below favor ablative techniques in terms of better preserving ovarian reserve without increased risk of recurrence.
