The end of the gastrointestinal tract has two important muscles that are placed in a ring around the anus. Both muscles are controlled by different parts of the nervous system.
During the internal sphincter muscle of the anus (Internal anal sphincter muscle) is supplied by involuntary nerve fibers, the external sphincter (External ani sphincter muscle) in connection with voluntary nerves. Due to this innervation, the internal sphincter not control by your own will. The external sphincter of the anus, on the other hand, can controlled open or locked.
The real job of these two muscles lies in the Regulation of defecation. Together with the so-called Levator ani muscle, the inner and outer muscles of the anus form the Closing apparatus of the rectum (rectum). In addition, the Sphincter muscles the end section of the gastrointestinal tract and thus form the anal canal. This channel can be a Length of about two to four centimeters accept.

For advanced hemorrhoids that clearly protrude from the anus, a more extensive therapy to be necessary. Especially the so-called Sclerotherapy is one of the most frequently performed treatment measures. In this procedure will be small portions of the hemorrhoid fixed and then with a substance that provokes inflammatory reactions (for example Polidocanol), treated.

In addition, some of the affected patients react oversensitive to the adhesive material of the collection bag. In addition, it can praeter too immediately after the creation of the anus inflammatory reactions in the surgical field come. Wound healing disorders are also not uncommon in patients with anus praeter. If complications arise after creating an anus praeter, a further surgical intervention be performed. Although many of the affected patients feel restricted in their everyday life, it must be stated that people with anus are basically praeter same activities can exercise like other people.
