A mannitol-bisacodyl regimen for radiological visualization of the colon.

The effectiveness of a 20% solution of mannitol-bisacodyl for oral use in preparing patients for barium enemas was investigated, in an investigator-blind control situation. The results were evaluated and compared with other methods currently in use. No comparative study where mannitol had been used could be found in the world literature. The mannitol-bisacodyl regimen was found to be an acceptable and reliable method for colon preparation in a high percentage of cases. Side-effects and changes in electrolyte balance of body fluids were recorded. The regimen was found to be safe for use on any patient irrespective of race, age or clinical condition and is not contraindicated in cases of cardiac and renal failure.
