Assessment of colon transit time is the most useful tool to evaluate disorders of colonic motility. It is especially helpful in making a pathologic diagnosis and for planning management in patients with complaints of constipation. Currently, several techniques for assessing colon transit time are available. Assessment of colon transit by radio-opaque markers has been most widely used. This study is simple and inexpensive, as well as reliable. However, it requires good compliance on the part of the patient, produces radiation exposure, and does not measure the transit of a true meal [1–3].
