Preoperative imaging evaluation may be useful for determining the position of recti abdominis muscles before their correction. The purpose of this study is to evaluate the accuracy of ultrasonography to measure the width of rectus abdominis muscle diastasis.
Rectus diastasis was measured by ultrasonography preoperatively in 20 females. Rectus diastasis was measured in seven levels along the anterior rectus sheath by ultrasound after sustained deep inspiration and after expiration. Rectus diastasis, at the same levels, was also measured after its exposition during abdominoplasty by two independent observers, using a surgical compass. These values were compared using Wilcoxon's statistical text, for non independent values.
There was no significant difference between the values obtained by ultrasound and those measured during surgery in the supra-umbilical levels and at the level of the umbilicus. However, below the umbilicus these values differed significantly, showing smaller values in the imaging evaluation.
Ultrasonography is an accurate method to measure rectus diastasis above the umbilicus and at the umbilical level.
术前影像学评估可能有助于在矫正腹直肌之前确定其位置。本研究的目的是评估超声测量腹直肌分离宽度的准确性。
对20名女性患者术前进行超声测量腹直肌分离情况。在持续深吸气后和呼气后，通过超声沿腹直肌前鞘在七个水平测量腹直肌分离情况。在腹壁成形术中暴露腹直肌后，由两名独立观察者使用手术圆规在相同水平测量腹直肌分离情况。对于非独立值，使用威尔科克森统计检验比较这些值。
在脐上水平和脐水平，超声测量值与手术测量值之间无显著差异。然而，在脐下这些值有显著差异，影像学评估显示的值较小。
超声是测量脐上和脐水平腹直肌分离的准确方法。
