For colonic transit radiomarkers:

  • Fecal impaction should be addressed prior to study
  • Figure 1 algorithm: If >80% of markers remain in colon on day 4 or 5, this is an abnormal study. “Children are considered as having slow transit constipation when there is a delay in transit, with the pellets spread throughout the colon. When the delay occurs and over 50% of the markers are held up in the rectosigmoid colon, children are labeled as having rectal outlet obstruction”
