Objective: To study the success rate of hysteroscopic adhesiolysis and the spontaneous recurrence rate of intrauterine adhesions (IUAs) in patients with Asherman syndrome.
Design: Cohort study.
Setting: University-affiliated hospitals.
Patient(s): A total of 638 women with Asherman syndrome were included, all diagnosed using hysteroscopy, and operated on between 2003 and 2013.
Intervention(s): Hysteroscopic adhesiolysis.
Main outcome measure(s): Hysteroscopic adhesiolysis was classified as successful if a normalization of menstrual blood flow occurred, along with a restored, healthy, cavity anatomy, free of adhesions, with hysteroscopic visualization of ≥ 1 tubal ostium. Recurrences of adhesions were diagnosed using hysteroscopy after an initial successful procedure.
Result(s): A first-trimester procedure preceded Asherman syndrome in 371 women (58.2%) and caused adhesions of grades 1-2A. In 243 (38.1%) women, a postpartum procedure caused IUAs of grades 3-5. The procedure was successful in 606 women (95%), and restoration of menstrual blood flow occurred in 97.8%; IUAs spontaneously recurred in 174 (27.3%) of these cases. High grades of adhesions were predictive of a higher chance of spontaneous recurrence of adhesions.
Conclusion(s): In 95% of women with Asherman syndrome, a healthy uterine cavity was restored with hysteroscopic adhesiolysis, in 1-3 attempts, with a 28.7% recurrence rate of spontaneous IUAs.
