Factors That Impact Fertility after Hysteroscopic Adhesiolysis for Intrauterine Adhesions and Amenorrhea: A Retrospective Cohort Study.J Minim Invasive Gynecol. 2020 01; 27(1):54-59.JM
To identify factors that affect reproductive outcomes after hysteroscopic adhesiolysis in patients with severe intrauterine adhesions (IUAs, scored between 9 and 12 according to the American Fertility Society classification) and amenorrhea.
A retrospective cohort study.
A university-affiliated hospital.
One hundred fifty-one patients with severe IUAs and amenorrhea.
Patients were diagnosed via hysteroscopy and underwent at least 1 hysteroscopic adhesiolysis between May 2012 and January 2016.
MEASUREMENTS AND MAIN RESULTS
Of 151 patients, 12 were lost to follow-up, and 139 were included in the study with a follow-up period ranging from 2 to 6 years. Of the 139 evaluable patients, 107 (77%) recovered with a normal uterine cavity (free of IUAs), 28 (20.1%) had improved uterine cavity (fewer IUAs), and 4 (2.9%) showed no improvement. Moreover, 79 patients (56.8%) recovered with normal menstruation, 54 (38.9%) showed increased frequency of menstruation, and 6 (4.3%) had persistent amenorrhea. Seventy-seven (55.4%) became pregnant, of whom 13 had a spontaneous miscarriage, 11 birthed prematurely (at 31-36 gestational weeks), 44 experienced term delivery, and 9 were still pregnant at the end of the study. Age >32 years (p = .002, odds ratio [OR] = 3.442), >2 surgeries (p = .027, OR = 2.969), cervical canal adhesions (p = .047, OR = 2.112), and disease course >6 months (p = .037, OR = 2.335) were risk factors for infertility in patients with severe IUAs and amenorrhea.
Younger age, earlier treatment within the disease course, fewer cervical canal adhesions, and fewer surgical procedures improve the reproductive outcome in patients with severe IUAs and amenorrhea.
