Abstract To evaluate the efficacy of balloon dilation and injection of sodium hyaluronate combined with artificial cycle therapy for preventing the intrauterine readhesion of patients with severe intrauterine adhesion after the uterine separative operation. Methods：124 patients with severe intrauterine adhesions who had been given sodium hyaluronate injected into the uterine cavity and a 3-5ml balloon inserted for supporting the uterine cavity after hysteroscopic adhesions separation operation were involves in this study from June 2017 to June 2020. 60 patients in the observation group were given balloon dilatation in the first and the second week after operation，and 64 patients in the control group were not given balloon dilatation. All the patients in the two groups were treated with high-dose estrogen combined with artificial cycle. The recovery of uterine cavity and the menstrual situation of the patients in the two groups were followed up. Results：The rate of intrauterine readhesion (18.3%) of the patients in the observation group within 1 month after operation was significantly lower than that (40.6%) of the patients in the control group. The rate of menstrual improvement (83.3%) of the patients in the observation group was significantly higher than that (59.4%) of the patients in the control group (all P<0.05). Conclusion: Hysteroscopic intrauterine adhesion separation combined with postoperative balloon dilatation for treating the patients with severe intrauterine adhesions can significantly prevent their intrauterine readhesion, and can improve their menstrual recovery.
