Abstract: Intrauterine adhesions (IUAs) may lead to abnormal menstruation, infertility, and pregnancy-related complications. Hysteroscopic separation is the gold standard treatment for IUA and can be performed using a variety of instruments and methods, including cold scissors and electrotomy. However, it is unclear which method is more effective for relieving IUA, restoring uterine anatomy, and improving the pregnancy rate in women of childbearing age. This multicenter prospective randomized clinical trial included 218 women aged 20-40 years who were treated for IUA between 1 March 2021 and 30 June 2022 and followed for 1.5 years. The women were randomly assigned to a cold scissors group ( n = 109) or electrosurgical excision group ( n = 109). Second-look hysteroscopy was performed in all patients within 3-10 days after the end of the first postoperative menstrual period. The primary outcome was the change in American Fertility Society score. Secondary outcomes included postoperative menstrual blood loss, the recurrence rate, and the reproductive outcome. There was no significant difference in the curative effect of hysteroscopic adhesiolysis between the cold scissors group and the electrosurgical excision group (5 [interquartile range, 4-6] vs. 5 [interquartile range, 4-6], P = 0.729) or in the postoperative recurrence rate (27.5% vs. 30.6%, relative risk 0.901, 95% confidence interval 0.594-1.366, P = 0.623) or pregnancy outcomes between the two groups. Postoperative menstrual blood loss was significantly greater in the cold scissors group than in the electrosurgical excision group (65.1% vs. 48.1%, P = 0.029). The treatment cost was significantly lower in the cold scissors group ( P < 0.001). In conclusion, hysteroscopic adhesiolysis using cold scissors does not differ significantly from electrosurgery in terms of treatment efficacy, recurrence rate, pregnancy rate, or pregnancy-related complications in patients with IUA who have normal ovarian reserve and an endometrial thickness of ≥6 mm before ovulation. The cold scissors ploughing technique can increase menstrual blood loss and is a cost-effective procedure.
