What is defecography?

Defecography is an x-ray of the anorectal area that evaluates completeness of stool elimination, identifies anorectal abnormalities, and evaluates rectal muscle contractions and relaxation. During the examination, the patient's rectum is filled with a soft paste that is the same consistency as stool. The patient then sits on the toilet positioned inside an x-ray machine, and squeezes and relaxes the anus to expel the solution. The physician studies the x-rays to determine if anorectal problems occurred while the patient was emptying the paste from the rectum.
