Abstract
Background
Hysteroscopic adhesiolysis anatomically restores the uterine cavity in cases of Asherman’s syndrome (AS); however, the extent of endometrial fibrosis could determine the pregnancy outcome.
Objectives
To determine whether endometrial thickness could influence pregnancy outcome of hysteroscopic adhesiolysis in women with a history of AS.
Subjects and methods
This was a retrospective cohort study that included 41 women who attended Women’s Specialized Hospital, King Fahad Medical City from December 2008 to December 2015, presented with a history of infertility or recurrent pregnancy loss, and were diagnosed with intrauterine adhesions and treated by hysteroscopic adhesiolysis. To analyze the causative factors of AS, history of curettage, miscarriage, postpartum hemorrhage, hysteroscopy, endometritis, and any uterine surgery were recorded. Patients were followed up for 2 years to account for pregnancy. Patients were divided into two groups based on measurement of endometrial thickness in the midsagittal plane at mid-cycle of a menstrual period. Group A consisted of 26 patients with endometrial thickness ≤5 mm, and group B included 15 patients with endometrial thickness >5 mm. The main outcome measures included endometrial thickness and pregnancy outcome.
Results
Group A had significantly (P<0.001) lower pregnancy rates compared with group B (38.4% versus 80%, respectively). Five of 10 pregnancies (50%) from group A miscarried, compared with 1 of 12 (8.3%) pregnancies in group B. This was statistically significant (P<0.001).
Conclusion
Pregnancy rates were observed to be higher when the endometrium was >5 mm in thickness among patients with AS and miscarriage rates may be reduced in this group.
