3-dimensional anorectal manometry (3DARM) and 3-dimensional endoanal ultrasound (3DEAUS) have not been used to assess the anal sphincter complex (ASC) in primi gravida. This study was conducted to identify any correlation that may exist between 3DARM and 3DEAUS.
We analyzed 3DARM and 3DEAUS data of 101 consecutive primi mothers assessed in the late second trimester or early 3rd trimester. 3DARM was performed using the Given Imaging(®) Manoscan system and 3DEAUS was performed with the Olympus(®) RU 12M-R1 probe and EU-ME1 ultrasound system.
The mean age was 24.7 (SD-5.1) years. All patients had a normal Cleveland Clinic Incontinence Score. The mean resting pressure (RP) was 87.02 (SD-18.43) mmHg and the maximum squeeze pressure (SP) was 179.21 (SD-52.96) mmHg. The mean length of the high pressure zone was 3.67 (SD-0.52) cm. On 3DEAUS, there were three characteristic segments of the ASC that were identified; upper, middle and lower. Mean thicknesses for both internal anal sphincter (IAS) and external anal sphincter (EAS) were identified for primi gravida. IAS was thicker anteriorly and at 9 o' clock positions and EAS was thicker posteriorly. There was good correlation in the length of the ASC at each quadrant between 3DARM and 3DEAUS. There was no correlation between either RP or SP thickness of IAS or EAS at each level and quadrant.
Correlation is seen only in the length of ASC at each quadrant. No correlation exist between RP or SP and thickness of IAS and EAS.
三维肛肠测压法（3DARM）和三维肛管超声检查（3DEAUS）尚未用于评估初产妇的肛门括约肌复合体（ASC）。本研究旨在确定3DARM和3DEAUS之间可能存在的任何相关性。
我们分析了101例在孕中期晚期或孕晚期早期接受评估的连续初产妇的3DARM和3DEAUS数据。使用Given Imaging(®) Manoscan系统进行3DARM检查，并使用Olympus(®) RU 12M-R1探头和EU-ME1超声系统进行3DEAUS检查。
平均年龄为24.7（标准差-5.1）岁。所有患者的克利夫兰诊所失禁评分均正常。平均静息压力（RP）为87.02（标准差-18.43）mmHg，最大收缩压力（SP）为179.21（标准差-52.96）mmHg。高压区的平均长度为3.67（标准差-0.52）cm。在3DEAUS检查中，确定了ASC的三个特征段；上部、中部和下部。确定了初产妇肛门内括约肌（IAS）和肛门外括约肌（EAS）的平均厚度。IAS在前方和9点位置较厚，EAS在后方较厚。3DARM和3DEAUS在每个象限的ASC长度之间存在良好的相关性。在每个水平和象限，IAS或EAS的RP或SP厚度之间均无相关性。
仅在每个象限的ASC长度上存在相关性。RP或SP与IAS和EAS的厚度之间不存在相关性。
