为了研究肠易激综合征（ＩＢＳ）患者直肠肛门运动功能，测定了８０例ＩＢＳ患者和２０例正常人直肠肛门压力及排便功能。发现：①直肠静息压、肛门括约肌静息压及其最大缩窄压在ＩＢＳ腹泻组、便秘组及正常对照组均无显著差异。②肛管高压带长度在ＩＢＳ腹泻组及便秘组均显著高于正常对照组。③直肠壶腹部的感觉阈值、最大耐受量、直肠顺应性及直肠－肛门抑制反应的直肠扩张容量在ＩＢＳ腹泻组均显著低于正常对照组，肛门括约肌松弛率ＩＢＳ腹泻组与正常对照组无显著差异。④ＩＢＳ便秘组感觉阈值与正常对照组无差异，但其最大耐受量及引起直肠－肛门抑制反射的直肠扩张容量均显著高于正常对照组，其直肠顺应性和肛门括约肌松弛率显著低于正常对照组。
In order to study rectal anomotility in patients with irritable bowel syndrome (IBS), rectal anal pressure and defecation were measured in 80 IBS patients and 20 normal controls. The results showed: (1) Resting pressure at rectum, resting pressure of anal sphincter and its maximum constriction pressure were not significantly different between IBS diarrhea group, constipation group and normal control group. ② The length of anal pressure band in IBS diarrhea group and constipation group were significantly higher than the normal control group. ③ The sensory threshold, maximal tolerance, rectal compliance and rectal-anal rectum rectum expansion capacity in rectum ampulla were significantly lower in IBS diarrhea group than in normal control group. The anal sphincter relaxation rate in IBS diarrhea group and normal control group were Significant differences. ④ The sensory threshold of IBS constipation group was the same as that of the normal control group, but its maximal tolerability and the rectum-dilatation capacity of rectal-anal inhibition reflex were significantly higher than those of the normal control group, and the rectal compliance and the anal sphincter relaxation rate were significantly lower than those of the normal control group Control group.
