Irrigoscopy (colon x-ray)

Irrigoscopy is a technique used to visualize the entire large intestine, including the small intestine.
A thin probe that is inserted into the anal canal is used to pump thick X-ray contrast medium and air into the patient. The mucous membrane of the intestine is unfolded by the air, which manifests itself as a feeling of fullness.
When the colon is completely filled, x-rays are taken in various positions under fluoroscopy.

Common uses

  • Stool problems, stool irregularities, diarrhea
  • Assessment of the length, width and position of the intestine
