This is a prospective, randomized, single-blind study designed to evaluate the influence of individual approach on bowel preparation quality for colonoscopy. The investigators compare split-dose polyethylene glycol solution (PEG, Fortrans, Beaufour Ipsen) to modified split-dose PEG regarding predictors of inadequate preparation for colonoscopy.
Up to 22% of patients are not good prepared for colonoscopy and it is caused of aborted procedures and increased costs. There are identified predictors of inadequate bowel preparation before colonoscopy, but we still don't know if an individual approach improve the quality of preparation.
