Description
Summary:Abstract Purpose To compare the efficacy of ultrasound-guided alcohol sclerotherapy versus laparoscopic cystectomy for the management of ovarian endometriomas, focusing on complications, recurrence, pain relief, and healthcare costs. Methods We conducted a multicentre, randomized clinical trial across 20 centers in Spain. A total of 167 women aged 18–40 years with ovarian endometriomas (35–100 mm) were recruited between June 2018 and June 2022. Participants were randomized to receive either ultrasound-guided aspiration with ethanol sclerotherapy or standard laparoscopic cystectomy. Complications were graded using the Clavien–Dindo classification. Pain was assessed using a visual analogue scale (VAS) before and six months after treatment. Recurrence was defined as the reappearance of a cystic lesion at the treated site and analyzed using Kaplan–Meier curves and log-rank tests. The primary analysis followed an intention-to-treat approach and included 158 patients (sclerotherapy: n  = 84; cystectomy: n  = 74). The per-protocol analysis included 92 patients (sclerotherapy: n  = 57; cystectomy: n  = 37). Direct hospital costs, complication rates, recurrence, and pain relief were compared between groups. Results Intention-to-treat analyses show that complications were low in both groups (12%), most of which were Grade I–II, although 4.1% were Grade III in the surgery group. The cost of sclerotherapy was significantly lower (€472 vs. €2128, p  < 0.001). In per-protocol analyses, the cyst recurrence or reappearance was similar between the two groups, with rates of 25.7% (9 of 35) in the surgery group and 22.8% (13 of 57) in the sclerotherapy group ( p  = 0.16). Pain was improved or completely resolved in 49 of 55 cases (89.1%) in the sclerotherapy group and in 21 of 32 cases (65.7%) in the laparoscopic surgery group ( p  = 0.05). Conclusions Ultrasound-guided alcohol sclerotherapy is a safe, cost-effective alternative to laparoscopic cystectomy for the treatment of endometriomas, with comparable recurrence rates and pain relief.
