Primary Outcome Measures:
  • Quality of bowel preparation [ Time Frame: 2 months ]
    Quality of bowel preparation is assessed using Ottawa bowel preparation scale.


Secondary Outcome Measures:
  • Tolerability [ Time Frame: 2 months ]
    Tolerability of bowel preparation regimen is assessed by patient questionnaire.


Enrollment: 188
Study Start Date: January 2012
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: High volume PEG
Patients who are scheduled colonoscopy ingest high volume PEG(4L) for bowel preparation.
Drug: high volume PEG
high volume polyethylene glycol 4 lilter split-dosing 2L/2L two times
Active Comparator: Low volume PEG with low residual meals
Patients who are scheduled colonoscopy ingest low volume PEG(2L) and have a prepackaged low residual meals for bowel preparation.
Drug: Low volume PEG
low volume polyethylene glycol 2 liter one time

Detailed Description:

We aimed to evaluate the efficacy and tolerability of bowel preparation protocols with low volume PEG and low residue meals PEG compared to conventional high volume (4L) split-dose and standard diet.

Entry criteria: Entry criteria: Adult outpatients and inpatients (18-85 years of age) who undergo colonoscopy for screening, cancer surveillance or with gastrointestinal symptoms, other symptoms

Primary Outcome: Quality of bowel preparation (Ottawa scale) Secondary Outcome: Tolerability (preparation completion, side effect), acceptance, willingness
