Abstract/OtherAbstract:
BACKGROUND: Colonic transit study provides valuable information before surgical treatment is considered for patient with constipation. The radiopaque markers method is the most common way for evaluating colon transit time. The aim of this study is to compare the barium suspension with the radiopaque makers to assess the colonic mobility in patient with constipation.
METHODS: Colonic transit time was measured in 11 female patients with slow-transit constipation using both radiopaque markers and barium suspension method. In radiopaque markers method, the patient ingested 20 markers on the first day, and an abdominal radiograph was performed every 24h until 80% markers were excreted. In barium suspension method, the patient swallowed up to 50ml of 200% (w/v) barium meal. The abdominal radiographs were taken at the same time point as the former.
RESULTS: The total or segmental colonic transit time were obviously prolonged in all patients. Segmental transits time spent in the right colon, left colon and rectosigmoid for radiopaque markers and barium suspension method was, respectively, 30±6h and 34±7h; 38±9h and 32±6h; 40±8h and 38±10h. In the radiopaque markers method, total colonic transit time was 108±14h and it was 103±13h in the barium suspension method (P>0.05).
CONCLUSION: The barium suspension and radiopaque markers gave the similar results for colonic transit time. The barium suspension was a simple and cheap method for evaluating the colonic mobility.
