Defecography: Technique, Interpretation and Clinical Application

  • Ah Young KimEmail author


Defecography has been established as one of the primary examinations for patients with defecation disorder because of easy accessibility and cost-effectiveness. This examination enables, in real time, the morphologic as well as functional evaluation of the rectum and anal canal in a physiologic manner by injection of a thick barium paste into the rectum and its subsequent evacuation. Major indications of defecography include chronic intractable constipation, incomplete evacuation, incontinence, unexplainable rectal bleeding or mucous discharge, and suspected rectal prolapse. Technique and interpretation of this examination are outlined in this review.
