目的:
OBJECTIVE: To study whether intrauterine application of auto-crosslinked polymers of hyaluronic acid (ACP) gel after dilation and curettage (D&C) improves reproductive outcomes.
デザイン:
プロスペクティブ無作為化試験のフォローアップ。
DESIGN: Follow-up of a prospective randomized trial.
設定:
大学および大学付属の教育病院。
SETTING: University and university-affiliated teaching hospitals.
患者:
PATIENT(S): Women with a miscarriage at <14 weeks' gestation with at least one previous D&C were randomized to D&C plus ACP gel (intervention) or D&C alone (control). A hysteroscopy was performed after 8-12 weeks, and if intrauterine adhesion (IUAs) were encountered, adhesiolysis was executed.
介入:
参加者は治療後30ヵ月後にアンケートを受けた。
INTERVENTION(S): Participants received a questionnaire 30 months after treatment.
主なアウトカム評価項目:
進行中の妊娠とその後の妊娠の結果。
MAIN OUTCOME MEASURE(S): Ongoing pregnancy and outcome of subsequent pregnancies.
結果:
進行中の妊娠は、介入群の74.6%(50/67)対対照群の67.2%(43/64)で記録され、妊娠を希望している女性の94.3%(50/53)対71.7%(43/60)で記録された。妊娠に至るまでの期間の中央値は、それぞれ21.9カ月対36.1カ月であった。月経血量の減少は7.5%(5/67)対20.3%(13/64)、月経困難症は14.9%(10/67)対34.4%(22/64)であった。
RESULT(S): Ongoing pregnancies were recorded in 74.6% (50/67) of the intervention group versus 67.2% (43/64) of the control group, and in, respectively, 94.3% (50/53) versus 71.7% (43/60) in the women wishing to conceive. The median times to conception leading to a live birth were, respectively, 21.9 versus 36.1 months. Reduced menstrual blood loss was reported in 7.5% (5/67) versus 20.3% (13/64) and dysmenorrhea in 14.9% (10/67) versus 34.4% (22/64), respectively.
結論:
CONCLUSION(S): Application of ACP gel following D&C performed after miscarriage seems to have a favorable effect on subsequent reproductive outcomes in women with at least one previous D&C. Given the fact that the study was not powered for reproductive outcomes, the data should be interpreted with caution. The effect may be underestimated due to routine removal of IUAs.
