摘　　要：AIM:To evaluate the efficacy of reduced cathartic bowel preparation with 2 L polyethylene glycol(PEG)-4000 electrolyte solution and 10 mg bisacodyl enteric-coated tablets for computed tomographic colonography(CTC).METHODS:Sixty subjects who gave informed consent were randomly assigned to study group A,study group B or the control group.On the day prior to CTC,subjects in study group A were given 20 mL 40% wt/vol barium sulfate suspension before 3 mealtimes,60 mL 60% diatrizoate meglumine diluted in 250 mL water after supper,and 10 mg bisacodyl enteric-coated tablets 1 h before oral administration of 2 L PEG-4000 electrolyte solution.Subjects in study group B were treated identically to those in study group A,with the exception of bisacodyl which was given 1 h after oral PEG-4000.Subjects in the control group were managed using the same strategy as the subjects in study group A,but without administration of bisacodyl.Residual stool and fluid scores,the attenuation value of residual fluid,and discomfort during bowel preparation in the three groups were analyzed statistically.RESULTS:The mean scores for residual stool and fluid in study group A were lower than those in study group B,but the differences were not statistically significant.Subjects in study group A showed greater stool and fluid cleansing ability than the subjects in study group B.The mean scores for residual stool and fluid in study groups A and B were lower than those in the control group,and were significantly different.There was no significant difference in the mean attenuation value of residual fluid between study group A,study group B and the control group.The total discomfort index during bowel preparation was 46,45 and 45 in the three groups,respectively,with no significant difference.CONCLUSION:Administration of 10 mg bisacodyl enteric-coated tablets prior to or after oral administration of 2 L PEG-4000 electrolyte solution enhances stool and fluid cleansing ability,and has no impact on the attenuation value of residual fluid or the discomfortAIM: To evaluate the efficacy of reduced cathartic bowel preparation with 2 L polyethylene glycol (PEG)-4000 electrolyte solution and 10 mg bisacodyl enteric-coated tablets for computed tomographic colonography (CTC).

RESULTS: The mean scores for residual stool and fluid in study group A were lower than those in study group B, but the differences were not statistically significant. Subjects in study group A showed greater stool and fluid cleansing ability than the subjects in study group B. The mean scores for residual stool and fluid in study groups A and B were lower than those in the control group, and were significantly different. There was no significant difference in the mean attenuation value of residual fluid between study group A, study group B and the control group. The total discomfort index during bowel preparation was 46, 45 and 45 in the three groups, respectively, with no significant difference. CONCLUSION: Administration of 10 mg bisacodyl enteric-coated tablets prior to or after oral administration of 2 L PEG-4000 electrolyte solution enhances stool and fluid cleansing ability, and has no impact on the attenuation value
