肠道准备是CT结肠镜检查的重要组成部分，因为检查的准确性与结肠清洁的充分性密切相关，即使优化了所有其他获取参数，不良的肠道准备也可能损害诊断质量。大肠中残留的粪便和液体可能影响检查的解释，并可能增加假阳性和假阴性的数量。在这方面，大多数接受过CT结肠镜检查的患者表示，肠道准备是最不愉快的部分。不幸的是，到目前为止，关于理想的肠道准备技术还没有达成明确的共识，而且各诊断中心的准备策略也存在很大的差异。这篇综述文章的目的是描述肠道准备技术的发展和演变，以便选择最佳的方法来优化每位患者的CT结肠镜检查的诊断质量。2012爱思唯尔爱尔兰有限公司版权所有。
Bowel preparation represents an essential part of CT colonography, as the accuracy of the exam is strongly related to the adequacy of colonic cleansing, and a poor bowel preparation may compromise the diagnostic quality even despite optimization of all other acquisition parameters. Residual stool and fluid in the large bowel may affect the interpretation of the exam and may increase the number of false positives and false negatives. In this regard, the majority of patients having undergone CT colonography state that bowel preparation is the most unpleasant part.Unfortunately, to date no definite consensus has been reached about the ideal bowel preparation technique, and there is great variability in preparation strategies across diagnostic centers.The purpose of this review article is to describe the development and evolution of bowel preparation techniques in order to choose the best approach for optimizing the diagnostic quality of CT colonography in each patient.
