The Clinical Significance Of Colonic Transit Study In Diagnosis And Classfication Of Chronic Functional Constipation

Objective To study the value of colonic transit study in diagnosis and classf ication of chronic functional constipation . Methods In 23 patients with chronic functional constipation and 20 normal persons . Total and segmental colon transit time (CTT) were determined by using radiopaque marks and calculate the transit index (TI).The patients were divided into groups based on the result. Result The total and segmental CTT were significantly longer in the patients with constipation than normal person (P<0.01).The egmental CTT were significantly different between the patients with normal total CTT and normal person . According TI .dividing the patients with longer total CTT into slow transit constipation (STC)group and outlet obstructive constipation (00C)group. The segmental CTT were significantly different between the two groups. Conclusion The use of colonic transit study helps to identify the diagnosis and classfication of constipation .Furthermore the segmental CTT helps to identify patients,who may benefit from futher check-up.For the reasons, the colonic transit study should be acted as the first study in clinic.
