Intrauterine adhesions (IUA) are a challenging clinical problem in reproductive infertility. The most common causes are intrauterine surgery and abortions. We aimed to investigate whether early second-look office hysteroscopy can prevent IUA.
A single-center, prospective, two-armed, randomized controlled trial was designed to explore the efficacy of early office hysteroscopy after first-trimester induced abortion (suction dilatation and curettage [D&C]) and to further analyze fertility outcomes. Women aged 20-45 years undergoing suction D&C and desiring to conceive were recruited. Between October 2019 and September 2022, 66 women were enrolled, of whom 33 were allocated to group A (early hysteroscopy intervention). The women in intervention group A were planned to receive 2 times of hysteroscopies (early and late). In group B, women only underwent late (6 months post suction D&C) hysteroscopy.
The primary outcome was the IUA rate assessed using office hysteroscopy 6 months after artificial abortion. Secondary outcomes included menstrual amount/durations and fertility outcomes. In intervention group A, 31 women underwent the first hysteroscopy examination, and 15 completed the second. In group B (late hysteroscopy intervention, 33 patients), 16 completed the hysteroscopic exam 6 months after an artificial abortion. Twenty-one women did not receive late hysteroscopy due to pregnancy. The IUA rate was 16.1% (5/31) at the first hysteroscopy in group A, and no IUA was detected during late hysteroscopy. Neither group showed statistically significant differences in the follow-up pregnancy and live birth rates.
Early hysteroscopy following suction D&C can detect intrauterine lesions. IUA detected early by hysteroscopy can disappear on late examination and become insignificant for future pregnancies. Notably, the pregnancy outcomes showed a favorable trend in the early hysteroscopy group, but there were no statistically significant differences.

宫腔粘连(IUA)是生殖不孕领域极具挑战性的临床问题。最常见的病因是宫腔内手术和流产。本研究旨在探讨早期二次宫腔镜检查是否能预防 IUA。
采用单中心、前瞻性、双臂、随机对照试验设计,旨在探索早孕吸宫术后(吸引扩宫刮宫术[D&C])早期行宫腔镜检查的疗效,并进一步分析生育结局。招募年龄 20-45 岁、因流产而行吸宫 D&C 且有生育要求的患者。研究于 2019 年 10 月至 2022 年 9 月入组 66 例患者,其中 33 例患者被分配至 A 组(早期宫腔镜干预)。干预组 A 患者计划接受 2 次宫腔镜检查(早期和晚期)。B 组仅在吸宫 D&C 后 6 个月行晚期(宫腔镜检查)。
主要结局是人工流产后 6 个月行宫腔镜检查评估的 IUA 发生率。次要结局包括月经血量/持续时间和生育结局。干预组 A 中,31 例患者接受了第一次宫腔镜检查,其中 15 例完成了第二次检查。B 组(晚期宫腔镜干预,33 例)中,16 例在人工流产后 6 个月完成了宫腔镜检查。由于怀孕,21 例患者未接受晚期宫腔镜检查。A 组第一次宫腔镜检查时 IUA 发生率为 16.1%(5/31),晚期宫腔镜检查时未见 IUA。两组随访妊娠率和活产率均无统计学差异。
吸宫 D&C 后行早期宫腔镜检查可发现宫腔内病变。宫腔镜早期发现的 IUA 在晚期检查时可能会消失,对未来妊娠无影响。值得注意的是,早期宫腔镜组的妊娠结局呈良好趋势,但无统计学差异。
