Double Balloon Enteroscopy Preparation

This procedure requires navigation through your large and small intestine. This test requires preparation prior to the procedure. The large intestine, or colon, normally has debris throughout that requires cleansing prior to this examination. It is important to have a clean colon without debris for this examination. By the end of this prep, you should be moving your bowels so that only clear-yellow to light yellow liquid is passing. If your colon is not properly cleansed, this examination may miss finding important things. If the preparation is not good, you may be required to repeat the preparation and undergo the procedure again.
