A retrospective trial was carried out comparing four methods of bowel preparation on a randomly selected group of 503 patients. The methods of bowel preparations were: (1) X-prep alone, (2) X-prep plus three-day diet, (3) X-prep plus high colonic washout, (4) X-prep plus high colonic washout and three day diet. Faecal content was assessed independently by three radiologists and recorded on a linear analogue scale. Statistically significant differences were shown between the results obtained by each method; 97% of patients prepared by method (4) were acceptable, 89% of method (2), 83% of method (3) and 71% of method (1). It was also found that in-patients exposed to the same method of preparation as out-patients showed inferior bowel cleanliness although not to a statistically significant degree.
对随机选取的503例患者进行了一项回顾性试验，比较四种肠道准备方法。肠道准备方法如下：（1）单独使用X-prep；（2）X-prep加三天饮食调整；（3）X-prep加高结肠冲洗；（4）X-prep加高结肠冲洗及三天饮食调整。由三名放射科医生独立评估粪便含量，并在线性模拟量表上记录。各方法所得结果之间显示出统计学上的显著差异；采用方法（4）准备的患者中97%可接受，方法（2）为89%，方法（3）为83%，方法（1）为71%。还发现，与门诊患者采用相同准备方法的住院患者，其肠道清洁度较差，尽管未达到统计学显著程度。
