[Prospective study of preparation for colon double-contrast studies with enemas compared to oral...

In preparation for the colon double contrast method two groups of patients, both with identical dietary regimen, were compared. In one case an oral mannitol dose (20%) plus sodium picosulphate was given, in the other enema plus bisacodyl was applied. In a total of 132 patients, the group which was treated with mannitol showed significantly better cleansing results and a better coating with the contrast medium. Considerable side effects did not occur. Further advantages: reduced number of personnel required, less trouble for the patients, out-patient investigation possible.
