title: Functional disorders of the anus and rectum: findings on defecography.
abstract: In the past decade, interest in the anorectal region and the mechanism of continence and defecation has been increasing. Subsequently, techniques to visualize the anorectum have been introduced; evacuation proctography and defecography have been used to describe the dynamic radiologic evaluation of this area. Also, developments in anorectal manometry, electromyography, and transrectal sonography have renewed interest in defecography, particularly in categorizing the functional disorders including rectocele, intussusception and prolapse, enterocele, descending perineum syndrome, dyskinetic puborectalis muscle, solitary rectal ulcer syndrome, and incontinence.
