It is known as defecography
or evacuation proctography.
The commonly employed imaging methods include defecography
, contrast enhanced computerized tomography scan, MRI scan and ultrasonography including endorectal sonography.
Patients were evaluated using standardized clinical and paraclinical investigations such as anoscopy, colonoscopy, defecography
, colon transit time, endoanal sonography and anal manometry.
(which makes it possible to visualize the rectal emptying process) can be helpful if a diagnosis of rectal prolapse is being considered.
imaging tests, such as pelvic or abdominal sonography, MRI defecography
, spinal imaging, CAT scan of the abdomen and pelvis or other imaging tests
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.
This last consensus definition provides greater clarity in the definition and understanding of the problem, requiring criteria for functional constipation together with physiological evidence of the characteristic abnormal defecation dynamics through electromyography (EMG), anorectal manometry or imaging techniques such as defecography
Occasionally, if the clinical examination does not match the patient's symptoms, radiologic studies such as a defecography
can help identify the support defects.
Medical imaging modalities such as defecography
, dynamic magnetic resonance imaging and ultrasound help health care providers make effective treatment decisions.
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.
Constipation and incomplete evacuation are some of the indications for defecography
