Application of Puritybile capsules combined with different doses of Compound polyethylene glycol in bowel preparation

Objective The study aimed to observe the influence of Puritybile capsules combined with different doses of Compound polyethylene glycol (PEG) in bowel preparation. Methods 120 patients were set into three groups (group A, B and C) randomly (40 patients in each). Group A take the routine Compound polyethylene glycol treatment orally. On the basis of the same routine Compound polyethylene glycol treat-ment, group B added regular dose of Puritybile capsules. Group C took half dose of Compound polyethylene glycol and regular dose of Puritybile capsules. The cleaning effect and adverse reaction were compared among three groups. Results According to Ottawa Scale, the cleaning effects as well as the existing of air bubbles showed no significant difference among three groups. Among which group C was 30% lower than that of group A, 10% lower than that of group B. There was no statistical differences in adverse events. Conclusions Half dose of Compound polyethylene glycol and regular dose of Puritybile capsules can guarantee the ef-fect of bowel cleaning and lower medical expense of patients.
