Effect of oral polyethylene glycol at different time for painless colonoscopy preparation / 中国内镜杂志

ABSTRACT

Objective To compare the efficacy and comfort of oral polyethylene glycol at different time for painless colonoscopy preparation. Methods According to time of oral compound polyethylene glycol electrolyte powder, 173 painless colonoscopy patients were divided into group A, group B and group C. Patients in group A took 4 boxes of compound polyethylene glycol electrolyte powder for colonic preparation at 2200 on day 1 before the check, the time of painless colonoscopy is 830 ~ 1030. Group B patients took 1 box of compound polyethylene glycol electrolyte powder for colonic preparation at 2000 on day 1 before the check and took 3 boxes at 500 am on check day, the time of painless colonoscopy is 1030 ~ 1230. Group C patients took 1 box of compound polyethylene glycol electrolyte powder for colonic preparation at 2000 on day 1 before the check and took 3 boxes at 700 am on check day, the time of painless colonoscopy is 1330 ~ 1530. At last, we compare the colon cleanliness and comfort of patients among the three groups. Results There was no significant difference in instetinal cleanliness among the 3 groups (P > 0.05), but there was greatly significant difference in subjective tolerance among 3 groups (P < 0.05). Conclusion The 3 methods of having boxes of compound polyethylene glycol electrolyte power all have the satisfying effect for colonic preparation, but fractionated dose polyethylene glycol electrolyte power provides a better tolerance for bowel preparation of painless colonscopy.
