Measurement of colon transit time is the most basic and primary tool in evaluating disorders of colonic motility. In particular, it is helpful in pathologic diagnosis and for planning management in patients with constipation. Several techniques for measuring colon transit time currently exist. The standard measurement of colon transit time has been performed using radioopaque marker test. The radioopaque marker test is the most widely used method; it is simple to perform as well as being cost effective. But, this technique produces radiation exposure. Radionuclide scintigraphy and wireless motility capsules are other techniques used to measure colon transit time. In radionuclide scintigraphy, the transit of radioisotope is viewed by gamma camera; this approach has an advantage in that it uses minimal radiation and it allows a physiological assessment of gastrointestinal transit. Wireless motility capsules have been validated most recently, but this technique is not useful in Korea. This review presents the techniques used to measure colon transit time and the interpretations provided in different colon transit studies.
结肠通过时间的测量是评估结肠运动障碍的最基本和主要的工具。特别是，它有助于便秘患者的病理诊断和管理计划。目前有几种测量结肠通过时间的技术。结肠通过时间的标准测量一直使用不透射线标记物试验进行。不透射线标记物试验是最广泛使用的方法；它简单易行，具有成本效益。但是，这种技术会产生辐射暴露。放射性核素闪烁照相术和无线动力胶囊是另一种用于测量结肠通过时间的技术。在放射性核素闪烁照相术中，放射性同位素的通过情况由伽马相机观察；这种方法的优点是使用的辐射最小，并且可以对胃肠道通过情况进行生理评估。无线动力胶囊最近已经得到了验证，但在韩国这项技术并不适用。这篇综述介绍了用于测量结肠通过时间的技术，以及不同结肠通过研究中提供的解释。
