the fact that operations which do no more than fix the rectum in the sacral hollow are most successful and often cure incontinence if present is the best evidence that lack of support of the rectum is a prime cause of prolapse -- but it is equally likely that such operations work by preventing intussusception , now regarded as the likely mechanism ( rather than sliding herniation ) of complete rectal prolapse .
