Abstract
Rectal prolapse is an uncommon, disabling condition that has long fascinated surgeons. Rectal prolapse is a condition in which the rectum loses its internal support and protrudes or fails out of the anus. In the earliest phase, the rectal prolapse may be internal, but as the condition progresses, the rectum can be seen or felt outside of the body. When this occurs, it is called a complete rectal prolapse.
Rectal prolapse occurs due in part to I weakening of supporting structures within the peNis as well as loss of anal sphincter muscle tone. A lifelong habit of straining to have bowel movements may contribute, or it may occur as a late result of the stresses involved in childbirth. There may be a hereditary factor in some families. In most cases, however, there is no single cause which can be identified; it just happens.
Usually by taking a careful history and performing a complete anorectal examination. An examination called a videodefecogram may be helpful for diagnosis. Anorectal manometry measures muscle function, and also can diagnose nerve disorders which may affect the sphincter muscles.
There are several different surgical methods used to correct rectal prolapse. The simplest method involves implanting a band of elastic material under the skin around the outside of the anal muscle. This is called the Thiersch procedure.
Operating through the anus and removing the extra tissue from the rectum. This approach is called the Delorme procedure or the Altemeier procedure.
The most complicated approach involves operating through the abdomen and correcting the rectal prolapse from inside. This approach often involves removing a

segment of the colon or rectum which is too long, as well as resupporting the rectum from the inside. But it is the most permanent and effective operation for advanced cases.
Success depends on a number of factors, including the status of the anal sphincter muscles before surgery, whether the prolapse is internal or external, the overall condition of the patient and the surgical method used.
