Measurements of gastrointestinal tract transit times are used for evaluating motility disorders such as gastroparesis and slow transit constipation.
GASTROPARESIS
Gastric emptying time (GET) is indicated for the evaluation of patients with suspected gastroparesis. Delayed gastric emptying is implicated in such disorders as idiopathic and diabetic gastroparesis and functional non-ulcer dyspepsia.
SLOW TRANSIT CONSTIPATION
Colonic transit time (CTT) is indicated for the evaluation of colonic transit in patients with chronic constipation, to aid in differentiating slow and normal transit constipation.
