BACKGROUND/AIMS: Adequate preparation of the bowel is essential for accurate colonoscopic examination. Standard polyethylene glycol solution had been used as a bowel cleansing premedication. But many patients dislike the taste and saltiness of the polyethylene glycol solution. Comparison has made between colonic preparation with a new polyethylene glycol based solution that reduced the salt content and added flavoring in attempt to improve the palatability and to encourage patient compliance with the standard polyethylene glycol solution.
One hundred patients were randomized to receive either the new polyethylene glycol solution or the standard polyethylene glycol solution for their bowel cleansing preparation. Two gastroenterologists performing the colonoscopies were made unaware of the type of the preparation. The cleansing score and amount of residual fluids in each colonic segment was then evaluated.
There was no significant difference in the colonic cleansing score and amount of residual fluids between two groups. Patients' compliance was higher for the new polyethylene glycol solution group than for the standard polyethylene glycol group. There was no difference in side effects of bowel cleansing solutions. CONCLUSION: The new polyethylene glycol solution as a bowel cleansing method has a higher patient compliance rate and is as effective as the standard polyethylene glycol solution.
