Abstract:
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.

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...
Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...
