In patients with Crohn's disease involving the rectum (n=25), there was an inverse relationship between rectal capacity and the degree of proctitis. However, in patients with Crohn's disease not involving the rectum (n=22) the rectal capacity was similar to that of normal controls (n=20). The frequency of defaecation was not related to the degree of proctitis or to the pressure of a colectomy and ileorectal anastomosis. Control subjects had a significantly lower frequency of defaecation than patients with Crohn's disease irrespective of involvement of the rectum.
在患有累及直肠的克罗恩病的患者(n = 25)中,直肠容量与直肠炎程度呈负相关。然而,在未累及直肠的克罗恩病患者(n = 22)中,直肠容量与正常对照组(n = 20)相似。排便频率与直肠炎程度或结肠切除术及回肠直肠吻合术的压力无关。无论直肠是否受累,对照组的排便频率均显著低于克罗恩病患者。
