Abstract

Background: Miscarriage is a frequent problem that requires dilation and curettage in 30% of cases. This routine surgery may lead to intrauterine adhesions and severe infertility. Hyaluronic acid gel is known to reduce intrauterine adhesions after hysteroscopic surgery.

Objective: This study aimed to evaluate the rate of intrauterine adhesions after dilation and curettage for miscarriage with and without hyaluronic acid gel.

Study design: This was a multicentric (9 hospitals in France), prospective, open-label randomized trial. Patients who had a miscarriage between weeks 7 and 14 of gestation, required dilation and curettage, and wanted another pregnancy were eligible for the study. Women were randomly assigned in a 1:1 ratio to surgery alone (control group) or surgery with intrauterine instillation of hyaluronic acid gel (gel group). An office hysteroscopy was planned at 6 to 8 weeks after surgery. The primary endpoint was the rate of intrauterine adhesions during this office follow-up hysteroscopy. Two different follow-up fertility surveys were sent at 6 months and 1 year after the end of the intervention, respectively.

Results: Among the 343 patients who had curettage, 278 had hysteroscopy. After multiple imputation, the rate of intrauterine adhesions was lower in the gel group than in the control group (9.1% vs 18.4%, respectively; P=.0171). Among the 110 responders to the surveys, the overall pregnancy rate at 12 months after surgery was 64.5% (71/110), and similar in both groups (57.4% [27/47] in the control group vs 69.8% [44/63] in the gel group; P=.1789).

Conclusion: Intrauterine instillation of hyaluronic acid gel reduces the rate of intrauterine adhesions in women treated with dilation and curettage for miscarriage.
