fistulography - X-ray examination method, the essence of which is the introduction of contrast medium into the fistula with subsequent fluoroscopy field fistulous.In the process of diagnosis turns out the location of the fistula motion relative to the surrounding organs, its length, the presence of cavities and branches with which it communicates.Using the results fistulography specialist determines the method of excision of the fistula and develops further treatment of underlying pathology.

fistulography The procedure was performed as follows:

  1. Begin by filling the fistula contrast marker (usually oil-based or water-soluble iodine compounds).For this purpose, the outer edges of the fistulous lubricated antiseptic solution, and then the catheter is removed with a syringe into the lumen of the fistula available content.
  2. Next injected contrast agent (pre-heated to body temperature) to tight filling.To prevent leakag
    e of contrast agent catheter tightly clamped gauze ball.
  3. When the fistula is tightly filled, the catheter is removed and the hole quickly closed plaster or kleolom.If there are multiple fistulas in the study area, each of them filled alternately, starting with the largest.The amount of contrast agent based on the presence of the communicating cavities, the size and nature of the fistula.In order to prevent the appearance of manipulation of pain is performed under local anesthesia.
  4. The next step is the patient doing fluoroscopy during which serve several X-ray sighting.After the plaster is removed survey.

This contrast can arise spontaneously.If the substance follows bad, the doctor conducts active aspiration with a syringe, washing fistula furatsilina solution or saline solution and applying a sterile dressing.

When he appointed?

indication for this study is a fistula any location:

  • esophageal;
  • urocystic;
  • stomach;
  • rectovaginal;
  • intestine (small intestine, colon, rectum);
  • epidermal;
  • fistula in the respiratory system;
  • osteomyelitis (purulent lesion of bone tissue).

If a patient has a fistula with purulent discharge, diagnosis makes it possible to determine its source, whether sequestration, abscess, foreign body or a destructive lesion in the bone.


fistulography contraindicated in the following cases:

  • bleeding from the fistula motion.
  • Idiosyncrasy radiopaque drug.
  • presence of inflammation at the site of the fistula localization.
  • severe general condition of the patient, the cause of which is associated pathology (the failure of the respiratory, hemodynamic instability).

How to prepare?

In preparation for fistulography first determined whether there is no contraindications to the procedure, as well as allergic reactions to iodine-containing drugs.

examinee before the diagnosis is carried out survey radiographs of the affected area of ​​the body in two mutually perpendicular projections.
