The mechanisms of feces control is followed:(1)Perception of oncotic pressure by anal activates the kinetic response of defecation control;(2)The tension of the internal sphincter muscle of anus makes it closed inmost of the time.(3)Tension of anal sphincter and puborectalis mantain the angle between rectum and anal canal and make anal canal closed during the relaxation of anal sphincter ;(4)adaptability of rectum makes rectum engorge in the cases of the not too high pressure of rectum .Destruction of any mechanism above will result in fecal incontinence .

正常人的大便节制主要通过下列机制调控：(1)直肠对膨胀压的感知，激发控制排便节制的动力学反应；(2)肛门内括约肌的张力，使肛管在大部分时间处于关闭状态；(3)肛门外括约肌和耻骨直肠肌的张力，使得在肛门内括约肌松弛期间，维持肛管直肠角的存在，并使肛管处于闭锁状态；(4)直肠适应性，使得在直肠内压不致过高情况下，允许直肠充盈，上述机制中一种或几种受到破坏，就可以引起大便失禁。

Research of ultramicro- structure of anal sphincter in the cases of patients with fecal incontinence shows : shortness of smooth muscle cells of anal sphincter , destruction of normal structure of the rest cells , elongation of elastic tissue and increase of collagen fibers.
