Fractional small intestine passage

The fractional intestinal passage (FDP) is a radiological method for the preparation of the small intestine.

Here the patient drinks up to 300 ml of a water-soluble ionic contrast medium . X-rays are taken while the contrast agent naturally passes through the entire intestine. Their number and chronological sequence depend on the individual passage of the contrast agent.

With this examination, the passage time, i.e. the time that the contrast agent needs to pass through the small intestine, can be determined, or an ileus or a subileus can be diagnosed. It is used when the passage through the small intestine according to Sellink (enteroclysis) is contraindicated.

The method was introduced by Pansdorf in 1931 .
