Brief Summary

Colonoscopy is the best method to detect colorectal cancer and colonic polyps. Studies showed that adenoma detection rate positive correlation with good bowel preparation which makes bowel preparation an important issue. Hence, investigators conduct a clinical trial about adding another laxative agent to morning single dose low-volume PEG. To see if this new regimen could have non-inferior efficacy and lower life/sleep impact compared with standard regimen.

Outcome Measures

Primary Outcomes (1)

  • The Ottawa Bowel Preparation Scale

    Examiner will fill a case report form out after performing a colonoscopy. Score below or equal to 6 will be classified as "good preparation".

    Within 24 hours after colonoscopy

Secondary Outcomes (1)

  • Life disturbance

    30 minutes before patient receive colonoscopy

Study Arms (2)

Polyethylene glycol and bisacodyl

EXPERIMENTAL

In order to decrease the dose and frequency of polyethylene glycol, we added bisacodyl at the night before examination to facilitate the action of polyethylene glycol given solely in the morning of examination.

Drug: Polyethylene glycol and bisacodyl

Split-dose polyethylene glycol

ACTIVE COMPARATOR

The standard regimen of polyethylene glycol was used in this group. The participant of this arm receives polyethylene glycol in the evening before examination and the morning of examination .

Drug: Split-dose polyethylene glycol

Interventions

Intervention: Take 3 tablets (15mg) of stimulant laxatives Dulcolax® (bisacodyl) at 10pm the day before examination. Take two pack of osmotic laxative Klean-prep® powder (Polyethylene glycol) mixed with 2000ml water at 5am on the morning of examination.

Also known as: Dulcolax®, Klean-prep®
Polyethylene glycol and bisacodyl

Take two pack of Klean-prep® powder mixed with 2000ml water at 6pm before the day of examination, and take another two pack of osmotic laxative Klean-prep® powder mixed with 2000ml water at 5am on the examination day.

Also known as: Klean-prep®
Split-dose polyethylene glycol
