Effective colonoscopy requires an adequate level of cleansing as a basic component. This review will describe a compact review about general considerations in bowel preparation for colonoscopy and specific considerations for various patients. A low-fiber diet instead of a regular diet on the day before colonoscopy is an independent predictor of adequate bowel preparation. Improved bowel cleansing does not result from the routine use of enemas or prokinetics in addition to oral bowel preparation. For morning colonoscopy, a split method of 4 L polyethylene glycol on the day before and the day of colonoscopy is recommended, while patients scheduled for afternoon colonoscopy typically receive a full method of 4 L polyethylene glycol on the day of the procedure. Valid alternatives are 2 L polyethylene glycol plus ascorbic acid or 2 L sodium picosulphate plus magnesium citrate. Although there are no statistically significant differences between polyethylene glycol and oral sodium phosphate for colon cleansing, polyethylene glycol-based bowel preparation is advisable in most situations because of safety concerns.
有效的结肠镜检查需要足够的肠道清洁水平作为基本要素。本综述将简要介绍结肠镜检查肠道准备的一般注意事项以及针对不同患者的特殊注意事项。结肠镜检查前一天采用低纤维饮食而非常规饮食是肠道准备充分的独立预测因素。除口服肠道准备药物外，常规使用灌肠剂或促动力药并不能改善肠道清洁效果。对于上午进行结肠镜检查的患者，建议在检查前一天和检查当天采用分次服用4升聚乙二醇的方法，而安排在下午进行结肠镜检查的患者通常在检查当天采用一次性服用4升聚乙二醇的方法。有效的替代方法是2升聚乙二醇加抗坏血酸或2升匹可硫酸钠加枸橼酸镁。虽然聚乙二醇和口服磷酸钠在结肠清洁效果上无统计学显著差异，但出于安全考虑，在大多数情况下建议采用基于聚乙二醇的肠道准备方法。
