Efficacy of Ethanol Sclerotherapy Versus Laparoscopic Excision in the Treatment of Ovarian Endometrioma
Ethanol sclerotherapy and laparoscopic excision were equally effective in reducing pain and recurrence of ovarian endometriomas, with sclerotherapy showing a less significant decline in AMH levels.

This retrospective, single-center study (88 women aged 25–38; Jan 2020–Feb 2022) compared recurrence of ovarian endometrioma and symptom outcomes (dysmenorrhea and dyspareunia on visual analog scale) between ethanol sclerotherapy and laparoscopic ovarian cystectomy, with follow-up visits at 2, 6, and 12 months and serial pelvic sonograms for recurrence. It also assessed intervention-related complications and measured anti-Müllerian hormone (AMH) before and 6 months after treatment to evaluate ovarian reserve changes. Both approaches reduced dysmenorrhea and dyspareunia over 12 months, with no statistically significant differences in complication rates or endometrioma recurrence, although AMH decline was higher after laparoscopy; AMH levels at 6 months were not significantly different between groups. The authors note limitations consistent with retrospective, single-center design and physician-dependent assignment, and conclude that sclerotherapy may be an alternative, while requiring more studies. This paper is centrally about endometriosis — it directly compares ethanol sclerotherapy versus laparoscopic excision for ovarian endometrioma outcomes and ovarian reserve.
