defecography

def·e·cog·ra·phy

(def'ĕ-kog'ră-fē),
Radiographic examination of the act of defecation of a radiopaque stool.
[defecation + G. graphō, to write]

defecography

/def·e·cog·ra·phy/ (def″ĕ-kog´rah-fe) the recording, by videotape or high-speed radiographs, of defecation following barium instillation into the rectum; used in the evaluation of fecal incontinence.

defecography

[def′əkog′rəfē]
the radiographic examination of the rectum and anal canal of patients with defecative dysfunction. A barium sulfate paste is instilled directly into the rectum, and the patient is seated on a radiolucent commode in front of a fluoroscope. Lateral projections of the rectum and anal canal are recorded during defecation.

Anorectal manometry and a rectal balloon expulsion are indicated in those who fail to respond to laxatives but defecography only when anorectal manometry and a rectal balloon expulsion are inconclusive for defecatory disorders.
Occasionally, if the clinical examination does not match the patient's symptoms, radiologic studies such as a defecography can help identify the support defects.
MDR remains at the forefront of radiologic technology, as one of first centers to offer Breast MRI in an outpatient setting, and one of the only practices in the entire Tri-State area to routinely conduct complex MR studies including secretin MRCP and pelvic floor defecography.
Before operative treatment is performed, colonic and anorectal physiologic studies, including measurement of anorectal inhibitory reflex, anal canal pressures, radio-opaque marker colonic transit study, and video defecography, should be performed.
At the forefront of radiological technology, Manhattan Diagnostic Radiology was also among the first practices to introduce Breast MRI in an outpatient setting, and is one of the only practices to routinely conduct complex MR Defecography studies in the entire Tri-State Area.
Defecography, surface EMG, anal manometry, and colonic transit studies also may be useful.
Manometry provides information about the functional status of the anal sphincter and distal rectum, and often is used with other tests such as anal ultrasound, anal sphincter EMG, pudendal nerve terminal motor latency assessment, and defecography, said Dr.

When the prolapse is not demonstrable during the evaluation, defecography is useful for identifying rectoceles and other pathology that might be affecting evacuation.
The tests--colonic motility study, anorectal manometry, defecography, electromyography and pudendal nerve terminal motor latency--serve to differentiate a pelvic outlet obstruction, which is the problem in a majority of patients, from colonic inertia.
In the future, MRI will replace standard retrograde and micturating cystourethrogram and defecography in the presurgical evaluation of pelvic prolapses, said Dr.
Types of tests include manometry, electromyography, endoanal ultrasonography, defecography, magnetic resonance imaging, and saline continence testing, said Dr.
