A fistulogram is a test to look at a fistula, which is like an abnormal tube between organs or from an organ to the skin.
A sinogram is a test to look at a sinus. A sinus is like a fistula. But instead of connecting two organs, it's like a tube that's closed on one end.
Both of these tests use X-rays with a special dye that is injected into the area of the fistula or sinus. The dye allows the fistula or sinus to show up on the X-ray. A CT scan can also be used for these tests.
The test may be done to diagnose a fistula or sinus. These tests also help your doctor find out details about the fistula or sinus, such as where it is and the organs it affects. This helps your doctor plan how to treat the problem.
Your doctor may tell you how to prepare for the test. What you'll need to do depends on where the fistula or sinus is.
The test is usually done in a clinic or a hospital.
The test will take about 30 minutes to an hour.
