肛门搔痒是一种常见的疾患,但对其发病机理却所知甚少。一过性肛门搔痒是特发性的,而持续性的搔痒多伴有皮肤或肛门的原发病变。本文应用生理测压方法,探讨搔痒患者肛门括约肌的功能缺陷。共测定34例患者,并以年龄、性别相当的20例正常人,无胃肠道疾患者作对照。所有患者均无腹泻,部分伴有痔、皮赘和肛门脱垂病变,并通过直肠镜,乙状结肠镜检查和微生物、寄生虫学检查,除外了寄生虫或真菌引起的搔痒。紫外线照射下没有莹光,会阴涂沫,一例患者有白色念珠菌生长,一例有小的红串酵母菌接种,并没有发现 C.minutissimum 这种肛门搔痒症罕见病因的霉菌。 Anal itching is a common condition, but little is known about its pathogenesis.
