There are few contraindications. If evaluation of the colonic mucosa is what is clinically desired, then a double contrast barium enema is preferred. If screening for colon cancer, then CT colonography is preferred.

One of the most important considerations for a single contrast barium enema is the density of the barium or water-soluble contrast. If it is too dense, then not only will the fluoroscopic tube "burn out" the background image and obscure overlapping loops, it will also obscure smaller and sometimes large!

You want contrast that's dense enough to see filling defects, but not too dense. Where this optimal density lies is dependent on one's fluoroscopic equipment and available contrast solutions. Water-soluble contrast e. Some radiologists also prefer giving the patient 1 mg of glucagon IV or SQ before the exam to relax the colon, but this is not mandatory, and has questionable utility. The following technique is for a standard single contrast exam.

If the exam is for postoperative leak or for evaluation of a known lesion, it can be modified. During the exam, palpation should be performed to press out the contrast at the head of the contrast column. This allows for some evaluation of the mucosa. This is harder to do when the colon is completely full of contrast.

It may be impossible to compress the colonic flexures underneath the ribs. Don't slavishly follow a protocol sequence. If you need to break out of an imaging sequence to accomplish either of these goals The patient should be encouraged to stay hydrated and, if using barium, not to be alarmed if white material comes out in future stools.
