Vaporization of ovarian endometrioma using plasma energy: histologic findings of a pilot study.

In ten ovarian endometriomas of diameter exceeding 30 mm, managed by complete vaporization of the inner surface using plasma energy followed by cystectomy, we performed histologic evaluation of the depth of necrosis and the effectiveness of endometrial tissue ablation. We observed that plasma energy allows the ablation of endometrial tissue with minimal damage to the ovarian parenchyma, which suggests that this technique might be of particular interest for women with risk factors of postoperative ovarian reserve impairment, such as recurrent and bilateral endometriomas.

Direct proportional relationship between endometrioma size and ovarian parenchyma inadvertently removed during cystectomy, and its implication on the management of enlarged endometriomas.

Background: The aim of this study was to estimate whether or not the size of an endometrioma is related to the thickness of the ovarian parenchyma inadvertently excised along with the cyst wall.

Methods: We performed a retrospective study including 35 women who had undergone endometrioma cystectomy, using an ovarian tissue sparing procedure. In total 38 specimens were studied by three pathologists as three women presented bilateral localizations, and all cyst diameters measured at least 30 mm.
