Reproductive outcome following hysteroscopic adhesiolysis in Asherman's syndrome.

OBJECTIVE

To determine whether hysteroscopic adhesiolysis improves reproductive outcome in women with Asherman's syndrome and pregnancy failure.

SUBJECTS

Ninety consecutive women who had undergone hysteroscopic adhesiolysis of intrauterine adhesions during a 5-year period. Only women in whom at least two previous pregnancies had ended with either a spontaneous abortion or a premature delivery accompanied by fetal or neonatal mortality and a hysteroscopic diagnosis of intrauterine adhesions were enrolled.

RESULTS

Whereas pregnancy outcome prior to the operation was 18.3% term deliveries, 3.3% premature deliveries, 62.4% first-trimester abortions, and 16.0% late abortions, after hysteroscopic adhesiolysis pregnancy outcome was 68.6% term deliveries, 9.3% premature deliveries, 17.4% first-trimester abortions, and 4.7% late abortions. In women with two previous unsuccessful pregnancies, the operative success rate measured by delivering a healthy newborn improved from 18.3% preoperatively to 64% postoperatively. In women with three or more unsuccessful pregnancies the success rate improved from 18.3% to 75%. Successful outcome of adhesiolysis was observed in 61.9% of mild (stage I) and in 70.6% of moderate to severe cases (stages II and III) of intrauterine adhesions.

CONCLUSION

Hysteroscopic adhesiolysis in women with Asherman's syndrome and poor reproductive performance contributes significantly to a successful reproductive outcome.
