The present communication is an endeavor to assess the value of a simple motility index to separate patients with neurogenic or idiopathic fecal incontinence from those patients with the secondary form of the disease.
Study population consisted of 23 patients with idiopathic fecal incontinence and 13 patients with fecal incontinence secondary to surgical or obstetric trauma. They all had a standard anorectal manometric study after a 12-hour fast. A motility index was then prepared taking into consideration the peak sphincter pressure values, contractility endurance, and rectal sensory threshold.
Despite differences in the mean peak squeeze pressure and sensory threshold between the two groups, there were significant overlaps for all parameters of standard anorectal manometry in both groups. However, patients with idiopathic incontinence had an index of smaller than 28, and the group with the secondary form of incontinence had indexes higher than 30.
本报告旨在评估一种简单的动力指数在区分神经源性或特发性大便失禁患者与继发性大便失禁患者方面的价值。
研究人群包括23例特发性大便失禁患者和13例因手术或产科创伤继发大便失禁的患者。他们在禁食12小时后均接受了标准的肛门直肠测压研究。然后，综合考虑括约肌峰值压力值、收缩耐力和直肠感觉阈值，制定了一个动力指数。
尽管两组之间平均峰值挤压压力和感觉阈值存在差异，但两组标准肛门直肠测压的所有参数都有显著重叠。然而，特发性失禁患者的指数小于28，继发性失禁患者组的指数高于30。
1）传统肛门直肠测压的四个参数中，没有一个能准确区分神经源性失禁患者和继发性失禁患者。2）这里提出的肛门直肠动力指数可以准确区分这两组患者。3）在评估大便失禁患者时，该指数优于标准肛门直肠测压。
