Twenty-four markers are ingested in this case, and abdominal x-rays are taken 1, 24, 48, 72, 96, and 120 hours later. 23 of the 24 markers are retained on day 5, located within the descending colon and rectosigmoid.
Case Discussion
There are several variations in how a colonic transit study is conducted and how the findings are interpreted. If 24 markers are used, <5 markers should be present within five days in a patient with normal colon transit.
