This study was performed in 15 healthy control subjects (8 males- age 23-70 and 7 females age 20-74) as a way to compare the total and segmental colonic transit time with two different type of radiopaque markers. One type of markers was 3 mm cut sections of a radiopaque polietilene 14 French Levine tube, with a medium weight of 64.3 mg and a specific gravity (SG) of 1.28. The other type were 7 mm lenticular insoluble barium (lentils) with medium weight of 231 mg and a SG of 1.87. Each subject ingested 20 markers of each type with the breakfast and front and profile plain films of the abdomen were taken 24 and 48 hs after. The total colonic transit time for the polietilene markers was 17.7 hs and 27.3 hs for the barium type (BM) (p < 0.001). The segmental transit time for right colon was 2.4 hs (PM) and 9.7 hs (PM) and 9.7 hs (BM) (p < 0.001) in the left colon 9.5 hs (PM) and 11.3 hs (BM) and in rectoanun 5.9 hs (BM) with no statistical significance. Conclusion: the physical characteristics of the radiopaque markers can modify the results of the colonic transit times.
