CT fistulography technique, directly performed on the
scanner table by manual injection through the EFO of diluted CM using a syringe
and a venous cannula (A). An example of CT fistulography (B, C) in a 69-year-old
man with ulcerative colitis, previous right hemicolectomy, and repeated surgery
for complications; shortly after ileostomy closure (note drainage tube),
low-output ECF was diagnosed, with communication between the EFO (arrowhead in B)
and the opacified ileum.
