Colonic Transit Studies in Children
The studies listed below demonstrate the significance of the Abrahamsson method, also known as the Transit-Pellets method, in measuring colonic transit time in children and adolescents. Compared to other techniques, research by Wagener et al (2004) and Vande Velde et al (2013) found that the Abrahamsson method is the preferred method for this population.
