  Purpose

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.


Condition Intervention
Split-dose Bowel Preparation
Polyethylene Glycol Solution
Risk Factors Inadequate Preparation

Primary Outcome Measures:
  • the index of preparation quality for the whole colon [ Time Frame: 24 hours ] [ Designated as safety issue: No ]
    the percentage of patients with adequate bowel preparation; adequate preparation is defined as excellent, good and fair, inadequate is defined as poor or unprepared colon according to the Ottawa bowel preparation scale


Secondary Outcome Measures:
  • compliance safety [ Time Frame: 24 hours ] [ Designated as safety issue: Yes ]
    number of patients with completion of preparation number of patients with side effects of preparation in each group


Estimated Enrollment: 266
Study Start Date: August 2011
Estimated Study Completion Date: March 2012
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: split-dose polyethylene glycol solution
first dose (1,5 l) of polyethylene glycol solution taken at 6-7.00 in the evening before colonoscopy, second dose (1,5 l) taken at 5.30-6.00 in the morning of a day of colonoscopy; additional bisacodyl taken at 12.00 at the day before colonoscopy
Other: individual preparation for colonoscopy
The volume of polyethylene glycol solution depends on risk factors presented in each patient. Time of administration of second dose will be confirmed according to the time of colonoscopy. In case of constipation an enema before colonoscopy will be administered. All patients will give educational booklet of preparation before colonoscopy

Detailed Description:

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.
