Colonoscopy is the premier method for colonic evaluation and its diagnostic accuracy and therapeutic safety depends on the quality of the colonic cleansing. Bowel cleansing with polyethylene glycol and sodium phosphate provides cleansing with high-quality preparations with an acceptably low morbidity rate and a high degree of patient satisfaction in a cost-effective manner. Modifications have reduced the volume of the polyethylene glycol preparations. Sodium phosphate has been associated with electrolyte and osmolarity imbalances and nephrocalcinosis; therefore, its clinical use has been questioned. Polyethylene glycol may be safer in patients with a history of significant renal, heart, or liver disease.
结肠镜检查是结肠评估的首要方法，其诊断准确性和治疗安全性取决于结肠清洁的质量。使用聚乙二醇和磷酸钠进行肠道清洁可提供高质量的制剂，发病率低且患者满意度高，具有成本效益。改进措施减少了聚乙二醇制剂的用量。磷酸钠与电解质和渗透压失衡以及肾钙质沉着症有关；因此，其临床应用受到质疑。对于有严重肾脏、心脏或肝脏疾病史的患者，聚乙二醇可能更安全。
