Measuring colonic transit time with radiopaque markers is a useful diagnostic test in the investigation and evaluation of gastrointestinal disorders in adults and children. The Transit-Pellets method is suitable for patients presenting with symptoms where transit disturbance may be of pathophysiological and clinical importance, including chronic constipation and diarrhea. This method eliminates the need to perform calculations manually, with the GI Monitoring System, and allows calculation with X-ray.
This unique x-ray method can distinguish between normal, fast and slow colonic transit time (CTC) in men and women. It can differentiate slow and normal transit from constipation and identify segmental dysfunction of the colon in patients with constipation. It differentiates normal and rapid transit from diarrhea and identifies treatment effects in patients with chronic constipation. Eliminates the need for manual calculations.
The segmental and total transit time of the colon is calculated according to the distribution of the markers in the different segments of the intestine. The transit time is equal to the total number of retained markers divided by the daily dose, which results in a colonic transit time value that is compared with normal values. The technique provides a robust, economical and practical measurement and is easy to perform in all units with an X-ray device.
