Histological Evaluation of Ovarian Endometrioma Ablation Using a Dual-wavelength Diode Laser (LEONARDO® DUAL 45): a Pilot Study
Обзор
Background: Ovarian endometrioma is the most common manifestation of endometriosis and is associated with chronic pelvic pain, infertility, and reduced ovarian reserve. Surgical treatment options include cystectomy and ablative techniques. Recent evidence suggests that ablative approaches may better preserve ovarian reserve compared with cystectomy while maintaining comparable recurrence and pregnancy rates. However, limited histological data are available regarding the depth of tissue damage induced by ablative techniques and their ability to completely eradicate endometriotic tissue. Objective: This pilot study aims to histologically evaluate the effects of ex vivo ovarian endometrioma ablation using the LEONARDO® DUAL 45 dual-wavelength diode laser (980 nm and 1470 nm). The study will assess the completeness of endometriotic tissue ablation, the depth of laser-induced necrosis within the endometrioma pseudocapsule, and the extent of thermal injury to the surrounding ovarian tissue. Methods: Adult women undergoing laparoscopic surgery for unilateral or bilateral ovarian endometriomas ≥3 cm will be prospectively enrolled. Surgical treatment will consist of cystectomy in reproductive-age women and adnexectomy in selected peri- or postmenopausal women according to routine clinical practice. After surgical excision, ex vivo samples of the internal endometrioma wall will undergo laser ablation using two different laser settings. Histological examination will evaluate residual endometrial glands and stroma, depth of necrosis, and thermal damage to adjacent ovarian tissue. Clinical, surgical, and pathological data will also be collected. Study Design: Prospective, observational, pilot study involving a medical device. Approximately 30 patients will be enrolled, generating multiple histological specimens for analysis. The study is designed to provide preliminary evidence regarding the histological efficacy and tissue effects of dual-wavelength diode laser ablation of ovarian endometriomas.
