Whole-bowel transit in patients with the irritable bowel syndrome.
The transit of radiolabelled preparations through the stomach, small intestine and colon was monitored in ten patients with the irritable bowel syndrome. Five patients complained of diarrhoea, and five complained of constipation. The preparations comprised a non-disintegrating capsule and a multiparticulate system. Both preparations emptied from the stomach together and at the same rates in both groups of patients. In the patients complaining of constipation, the transit times through the small intestine were the same for both preparations. In the patients complaining of diarrhoea, the capsule passed through the small intestine slightly faster than the particles, but there were no significant differences in the small-intestinal transit rates of the two patient groups. Within the colon, the transit of the capsule was faster than that of the small particles. Although movement through the colon was, on average, faster in the group of patients complaining of diarrhoea, there was considerable intersubject variability, and the differences in transit rates between the two patient groups were not statistically significant.
