Functional fecal retention visualized by (111)In-DTPA colon transit scintigraphy.

Constipation is an extremely common problem in children, varying from mild and short-lived to severe and chronic. Chronic constipation is a serious childhood condition and requires further investigation, including blood test, colonoscopy, radio-opaque marker study, and/or scintigraphy. We present small bowel and colon transit scintigraphy of a 14-year-old girl with history of chronic constipation, abdominal pain, weight loss, and poor response to medical treatment. After oral administration of In-DTPA in water, planar and SPECT/CT images showed normal small bowel transit time and functional fecal retention in colon transit study.
