Objectives: To compare the efficacies of catheter-directed sclerotherapy (CDS) with 99% ethanol and surgery for ovarian endometrioma and their impact on the ovarian reserve. Methods: From January 2011 to June 2019, 71 patients who underwent surgical excision (n = 51) or CDS (n = 20) for symptomatic ovarian endometriomas were reviewed. To analyze the effect on the ovarian reserve, serum anti-Müllerian hormone (AMH) levels were compared before and after the procedure. Symptoms, serum cancer antigen 125 (CA-125), lesion size, recurrence, hospitalization, and complications were reviewed retrospectively. Results: During a mean follow-up of 22.3 months (range, 6 to 94 months), no significant difference in symptom relief was found between CDS and surgery (95.0% [19/20] and 92.2% [47/51], respectively, p > 0.999). The hospital stay was shorter with CDS than with surgery (2.6 ± 0.6 days and 4.1 ± 0.5 days, respectively, p < 0.001). There was no significant difference in serum AMH levels before and after CDS (2.3 (interquartile range (IQR) 1.1–5.3) ng/mL and 2.6 (IQR 0.9–4.9) ng/mL, respectively, p = 0.243), but there was a significant decrease in serum AMH in the surgery group (3.0 (IQR 1.3–5.5) ng/mL and 1.6 (IQR 0.7–3.2) ng/mL, respectively, p < 0.001). CA-125 decreased in both CDS and surgery groups (p = 0.001 and < 0.001, respectively). Two minor complications occurred in the surgery group, while no complication was observed in the CDS group. Conclusions: The therapeutic efficacy of CDS appears to be comparable to that of surgical resection for ovarian endometrioma. Ovarian function was well-preserved, and a shorter hospital stay was required in patients who underwent CDS. Key Points: • There was no significant difference in symptom relief between CDS and surgery (95.0% [19/20], 92.2% [47/51], respectively, p >0.999). • No significant difference in serum AMH levels was seen before and after CDS (2.3 (1.1, 5.3)* ng/mL, 2.6 (0.9, 4.9)* ng/mL, respectively, p = 0.243), whereas serum AMH levels significantly decreased after surgical resection (3.0 (1.3, 5.5)* ng/mL, 1.6 (0.7, 3.2)* ng/mL, respectively, p <0.001). *Median (25 quartiles, 75 quartiles) • The hospitalization period was shorter with CDS than with surgery (2.6 ± 0.6 days, 4.1 ± 0.5 days, respectively, p <0.001).
