[Preparation for colonoscopy: A comparison between 3 commercially available Golytely solutions].

The preparation for colonoscopy is essential for the results of the examination. The effectiveness of 3 commercially available Golytely solutions for colonoscopy (Original-Golytely-salt, Oralav and Delcoprep) were compared in a randomized prospective study. 310 outpatients were randomized into 3 groups. One of the above-mentioned solutions were used in these patients. Before the examination the patients were asked to drink 3 l of the given solution within 2 h. The colonoscopy was realized within 3-5 h after the end of preparation. Outcome criteria were the subjective acceptability of the solution for the patient, cleanness of the bowel and the formation of foam. In all 3 groups sufficient up to very good results could be achieved. There were no significant differences in the 3 groups. We conclude that the used procedure is absolutely sufficient to prepare for colonoscopy and that administration of liquids of more than 3 l or the use of enema or laxans on the previous day, are unnecessary. The suggested procedure can be used for children, too.
