The X-ray causes no discomfort. However, placement of the tube into the intestines can be uncomfortable. There is exposure to radiation. The radiation exposure may be more than for many other types of X-rays because of the length of time needed for the fluoroscopic examination. The small intestine is normal in size and contour.
Contrast travels through the intestines without reflux or obstruction and at a normal rate.
This test may not be able to evaluate portions of the intestines because of the catheter position or overlapping by contrast-filled intestines. An alternative may be an abdominal CT scan .
