Definition:

A defecography is a test in which X-rays are taken to assess anatomical problems occurring during the process of defecation. In this test, a thick barium paste is placed into the patient's rectum. The patient is then asked to sit on a special toilet to expel the paste. As this is happening, X-ray videos are taken to record the passage of the barium paste through the rectum.

Defecography is not a commonly prescribed procedure. If you are to undergo a defecography procedure, be sure that the procedure is conducted by, and the results are interpreted by, experts in analrectal motility.
