A gastrograffin enema involves the injection of water soluble gastrograffin into the rectum using a foley catheter (fig 1). This is followed by a series of x-rays of the abdomen to show the outline of the colon and rectum and anus.

INDICATIONS FOR A GASTROGRAFFIN ENEMA
This procedure will show any obvious abnormality of the colon, rectum and anus, and is particularly useful following surgery for rectal cancer, to check that the join (anastomosis) is intact, and not narrowed (strictured) or leaking, prior to planned reversal of temporary stoma.
