    Abstract:
    STUDY OBJECTIVE: To compare the recurrence rate, post-treatment American Fertility Society (AFS) score, ongoing pregnancy rate, and endometrial thickness of 3 secondary prevention therapies in preventing recurrent intrauterine adhesions (IUAs) and increasing pregnancy rates in infertile women after hysteroscopic adhesiolysis. DESIGN: A retrospective study. SETTING: A private fertility hospital. PATIENTS: A total of 200 consecutive infertile women, with the desire to have a baby and were diagnosed as having IUAs detected by hysterosalpingogram, who underwent hysteroscopic adhesiolysis for IUAs from January, 2018 to May, 2020. INTERVENTIONS: Women who underwent hysteroscopic adhesiolysis received hormone therapy, and one of the 3 secondary preventions: hyaluronic acid (HA) gel alone, intrauterine devices (IUDs) alone, or HA gel + IUD. MEASUREMENTS AND MAIN RESULTS: Of the 200 women included in the final analysis, 121 received HA alone, 59 were treated with IUD alone, and 20 received HA gel + IUD combination. The mean post-treatment AFS score for IUAs was significantly lower in the HA gel + IUD group than the HA alone or the IUD alone groups (adjusted p = .01 and p = .02, respectively). Multivariable analysis revealed a significantly lower recurrence rate in the women after treatment with HA gel + IUD than HA alone (adjusted odds ratio, 0.19; 95% credible interval [CreI], 0.03-0.88). Women treated with HA gel + IUD also had reduced post-treatment AFS scores compared with HA alone (β coefficients, -0.83; 95% CreI, -1.64 to -0.01). For ongoing pregnancy rates after in vitro fertilization, the adjusted odds ratio for HA gel + IUD vs HA alone was 2.03 (95% CreI, 0.44-11.00) and for IUD alone vs HA alone was 1.13 (95% CreI, 0.41-3.29), indicating nonsignificant differences. There were no differences observed in endometrial thickness on the day of embryo transfer among the 3 groups. CONCLUSION: The investigation of the primary outcome in reducing the recurrence rate IUA after treatment demonstrated that a combination of HA gel + IUD provides greater prevention of recurrent IUAs and may decrease post-treatment AFS scores for infertile women undergoing hysteroscopic adhesiolysis. However, for the secondary outcome of increasing pregnancy rates, there was no improvement in the ongoing pregnancy rates after in vitro fertilization.
