What is the role of defecography (evacuation proctography)?
- Defecography may identify the cause and help direct therapy if there is anorectal dysfunction.
- It may also show one or more of the following: rectocele, rectal intussusception (rectorectal or intraanal), external rectal prolapse, and enterocele.
- Optimal diagnosis and management require correlation of defecography findings with history, physical examination, nonimaging tests of anorectal function, and often endoanal ultrasound.
