Introduction Fecal incontinence is a complex problem of diverse causes [1]. Childbirth and anorectal surgery are the main causes because the external anal sphincter and the pudendal nerve may be damaged. A systematic evaluation of the patient should reveal the underlying pathophysiology and lead to appropriate therapy [2].
OBJECTIVE: To use magnetic resonance images of living women and 3-dimesional modeling software to identify the component parts and characteristic features of the external anal sphincter (EAS) that have visible separation or varying origins and ...
How the anus works There are two rings of muscles in the anal canal that form the anus or anal canal (back passage); the internal anal sphincter and external anal sphincter. Either or both can become weak, due to childbirth, constipation and straining to have your bowels open, surgery or general wear and tear.
Loss of control of your bowel (faecal incontinence) can happen to different degrees and can happen to men and women of all ages. You must not be embarrassed about asking for help as there are ways in which we can treat the problem.

Defects in the external anal sphincter were defined at each level and recorded in ...
