Defekography is a medical imaging technique used to evaluate rectal emptying and pelvic floor function. It is a type of dynamic fluoroscopy that involves a radiologist observing and recording the process of defecation in real-time. The procedure typically involves the patient being seated on a special fluoroscopy chair. Before the examination, the patient's rectum is filled with a contrast material, usually barium, which is visible under X-ray. Sometimes, other contrast agents may be used for the vagina or small bowel to assess their function simultaneously.

During the examination, the patient is asked to go through the normal process of defecation. The radiologist uses fluoroscopy to visualize the movement of the contrast material as it passes through the rectum and out of the anus. This allows for the assessment of various aspects of defecation, including the degree of rectal emptying, the presence of rectal prolapse (where the rectum protrudes), rectocele (a bulge of the rectum into the vagina), enterocele (a bulge of the small intestine into the pelvis), and the coordination and movement of the pelvic floor muscles.

Defekography is often used to diagnose conditions that cause difficulty with bowel movements, such as constipation, fecal incontinence, and pelvic floor dysfunction. It can help identify anatomical abnormalities and functional problems that may be contributing to these symptoms. The information obtained from a defekography study can guide treatment decisions and help healthcare providers develop personalized management plans for patients with defecation disorders. The procedure is generally considered safe, with the primary risks being those associated with radiation exposure, which is kept to a minimum by trained professionals.
