Patient Data
Age: 75 years
Gender: Female
From the case:
Slow colon transit
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/116747/annotated_viewer_json?iframe=true\u0026lang=us"}
Twenty-four markers are ingested in this case, and abdominal x-rays are taken 1, 24, 48, 72, 96, and 120 hours later. 6 of the 24 markers are retained on day 5, located within the descending colon and rectosigmoid.
There are also post operative changes and evidence of CD insertion at the lower lumbar spine.
Case Discussion
There are numerous 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.
