本文对32名正常人及18名保留肛门括约肌根治切除病例进行了肛肠压力测定,对其肛肠生理状态及其影响因素作了初步探讨。本组测得健康成人肛门括约肌静压75.51±3.52cm H_2O,挤压129.58±3.28cm H_2O,该正常值与国外报道相似。扩张直肠下端可出现肛肠松驰反射,肛管部高压带引出,未发现明显性别和年龄方面的差异。 In this paper, anorectal pressure was measured in 32 normal people and 18 cases of anorectal sphincter resection. The physiological status of the anus and its influencing factors were discussed. In this group, the healthy anal sphincter had a static pressure of 75.51±3.52 cm H 2 O and a compression of 129.58±3.28 cm H 2 O. The normal value was similar to that reported in foreign countries. Dilatation of the rectum may occur at the lower end of the rectum and a reflex of the anus may occur. The high pressure zone of the anal canal leads out. No significant gender and age differences have been found.
