The objective is to evaluate the inter-recti distance on ultrasound measurement at different locations in healthy nulliparas. Electronic databases were searched for studies describing the inter-recti distance measured by ultrasound in healthy nulliparas. We excluded studies without descriptions of the measurement position or the condition of the abdominal wall. A meta-analysis was performed to evaluate the inter-recti distance on ultrasound measurement. Seven eligible studies with 295 healthy nulliparas were included. The location of the inter-recti distance measurement by ultrasound was not uniform. The pooled data divided the measurement locations into three areas. The meta-analytic summary values of the umbilical inter-recti distance of the nulliparas was 8.77 mm (6.56-10.99 mm), the distance at the epigastric area was 7.22 mm (2.76-11.68 mm), and that at the infraumbilical area was 4.09 mm (1.55-6.64 mm). The maximal reported inter-recti distance in healthy nulliparous women is smaller than 10 mm on ultrasound measurement at all locations and the range in the umbilical area is larger than that in the epigastric, infraumbilical areas. The values for the inter-recti distance reported in this systematic review can be used as the reference of feasible and desirable distance of the rectus muscles after rectus fascia plication. The limitation was that the methodological quality of the assessment in most studies was unclear or low.
目的是评估健康未产妇不同部位超声测量的腹直肌间距。检索电子数据库以查找描述健康未产妇超声测量腹直肌间距的研究。我们排除了未描述测量位置或腹壁状况的研究。进行荟萃分析以评估超声测量的腹直肌间距。纳入了7项符合条件的研究，共295名健康未产妇。超声测量腹直肌间距的位置并不统一。汇总数据将测量位置分为三个区域。未产妇脐部腹直肌间距的荟萃分析汇总值为8.77毫米（6.56 - 10.99毫米），上腹部区域为7.22毫米（2.76 - 11.68毫米），脐下区域为4.09毫米（1.55 - 6.64毫米）。健康未产妇超声测量的所有部位最大腹直肌间距报告值均小于10毫米，且脐部区域范围大于上腹部、脐下区域。本系统评价中报告的腹直肌间距值可作为腹直肌筋膜折叠术后腹直肌可行和理想间距的参考。局限性在于大多数研究评估的方法学质量不明确或较低。
