The term rectal prolapse implies the descent of a complete circumference of rectal wall through the anus. Frequently this term is applied erroneously to haemorrhoids or to a prolapsed mucosa of the anal canal. A true rectal prolapse is the protrusion of a complete thickness of rectal wall across the anal orifice. The rectal prolapse is a disease which occurs mainly at two extremes of life, the mucosal one in fact is more common in babies whereas the complete prolapse is diagnosed most of all in elderly patients. Adults in over 90% of the cases, are elderly women.
