Comparison of three oral regimens with compound polyethylene glycol electrolyte for bowel preparation

Abstract

Objective To evaluate the effects of three methods with oral compound polyethylene glycol electrolyte powder. Methods A total of 180 patients scheduled for colonoscopy were prospectively randomized into three groups, group A (n=67), group B (n=54) and group C (n=59), which received 4-L split-dose PEG, 3-L split-dose PEG and 4-L whole-dose PEG, respectively. The colon cleansing quality, the access time and polyp detection were evaluated. Results The access times of the 3 groups were(10.07±5.219)min, (10.19±4.903)min and (11.05±5.306)min, respectively, which had no significant differences (P>0.05). However, in terms of the quality of colon cleansing, group A was superior to group B, and there was significant difference in the scores of recto-sigmoid colon, mid colon, right colon, total fluid quantity as well as total score between the two groups(P 0.05). Conclusion 4-L split-dose PEG is better than the other 2 regimens in the colon cleansing quality, so it can better reach the intestinal cleaning standards before enteroscopy, which is a more suitable regimen for bowel preparation.
