What is defecography?
Defecography is a radiological examination used to study pelvic floor dysfunctions that cause problems with defecation
It is performed using a diluted baryta contrast medium, injected directly into the rectal ampulla.
In some cases, if required, the loops of the small intestine are also opacified with baryta contrast medium by mouth, the bladder with iodinated contrast medium by positioning a bladder catheter or even the vagina (in women) to study the reciprocal relationships of the opacified organs during the defecation.
What is defecography for?
Defecography allows you to study the phases of defecation and to identify any pathological changes that compromise the normal emptying of the rectal ampoule.
It is therefore indicated in case of chronic constipation, incomplete evacuation problems, incontinence, rectal prolapse, rectocele or cystocele.
In case of incontinence, it offers clues about the possible causes and extent of the problem.
Defecography, which patients can undergo the examination?
All patients suffering from above problems except pregnant women.
Is it painful or dangerous?
Defecography is neither painful nor dangerous.
How does defecography work?
The rectal ampulla is filled with a high-density barium-containing contrast medium using a syringe with a catheter cone.
This simulates the consistency of stool.
The patient is then made to sit on a special seat and the radiography is carried out using a device that allows to resume the movements of the rectum and possibly of the further previously opacified hollow organs.
Shooting is done sideways.
During the exam, the operator will ask the patient to contract the pelvic muscles.
The examination ends with the expulsion of the barium.
