Colonic Transit Time and Fecal Impaction in Children With Cy
A Study was conducted to evaluate the total and segmental colonic transit time in children and adolescents with cystic fibrosis (CF) based on the presence of constipation and radiological fecal impaction.

CF-associated constipation was diagnosed for Paediatric Gastroenterology Hepatology and Nutrition criteria. Total and segmental colonic transit time was determined using radiopaque markers. Fecal impaction on plain abdominal radiography was assessed based on the Barr score.

--34 patients were participated. Constipation was found in 44.1% of children and adolescents, predominantly in girls.

--The total colonic transit time and the segmental right colon transit time were significantly longer in CF-associated constipation group than in the group of patients without constipation.

--The frequency of radiological fecal impaction was similar in patients with and without CF-associated constipation.

--There was no relationship between radiological fecal impaction and the total and segmental colonic transit time.

Conclusively, children and adolescents suffering from CF-related constipation had a longer total and segmental right colon transit time. Patients with and without radiographic fecal impaction had similar colonic transit times.
