Defecography

Defecography or defaecography is a diagnostic radiological examination of the rectum and anus used to evaluate defecation. This procedure is performed to identify any abnormalities in the structure or function of the rectum and anus that may cause fecal incontinence or constipation.

Procedure

Defecography is performed by inserting a soft paste made of barium sulfate into the rectum of the patient. The patient is then asked to sit on a specially designed radiolucent commode. X-ray images are taken before, during, and after the defecation process. The images provide valuable information about the anatomy and function of the rectum and anus.

Indications

Defecography is indicated in patients with symptoms of fecal incontinence, constipation, rectal prolapse, and rectocele. It can also be used to evaluate the success of surgical treatments for these conditions.

Limitations

While defecography provides valuable information, it has some limitations. It is an invasive procedure and may cause discomfort to the patient. The procedure also exposes the patient to a small amount of radiation. Furthermore, the artificial conditions under which defecation is simulated during the procedure may not accurately represent the patient's normal defecation process.
