✦ Synopsis

Mean segmental transit time of radiopaque markers through the right colon, left colon and rectosigmoid areas of adults and children has been calculated from their distribution on consecutive plain films of the abdomen. Overall mean transit does not differ significantly in the large bowel between adults and children. However, there are regional differences within the colon in relation to age. Mean transit time in the right colon is 13.8 hours in adults and 7.7 in children (p < 0.01). Corresponding ~alues in the left colon are 14.1 and 8.7 hours (p < 0.02) and, in the rectum, 11 and 12.4 hours (p = NS). The percentage of the mean total large bowel transit time spent in the right colon, left colon and rectosigmoid area are respecti,.-ely for adults and children 33 • 4 and 28 ~ 3 per cent (p = NS); 39 = 4and 32 :-~ 4 per cent IP = NS); and 28 = 4 and 41 = 4 per cent (p < 0.05), indicating a relative stagnation in the rectoslgmoid area of children. These physiologic differences may have implications in diseased states.
