Mean segmental transit time of radiopaque markers through the right colon, left colon and rectosigmoid areas of adults and children has been calculated form 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 less than 0.01). Corresponding values in the left colon are 14.1 and 8.7 hours (p less than 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 respectively for adults and children 33 +/- 4 and 28 +/- 3 per cent (p = NS); 39 +/- 4 and 32 +/- 4 per cent (p = NS); and 28 +/- 4 and 41 +/- 4 per cent (p less than 0.05), indicating a relative stagnation in the rectosigmoid area of children. These physiologic differences may have implications in diseased states.
通过成人和儿童腹部连续平片上不透射线标志物的分布情况，计算出其在右半结肠、左半结肠以及直肠乙状结肠区域的平均节段转运时间。成人和儿童在大肠的总体平均转运时间无显著差异。然而，结肠内存在与年龄相关的区域差异。右半结肠的平均转运时间在成人中为13.8小时，在儿童中为7.7小时（p<0.01）。左半结肠的相应值分别为14.1小时和8.7小时（p<0.02），直肠的相应值为11小时和12.4小时（p=无显著性差异）。右半结肠、左半结肠和直肠乙状结肠区域在成人和儿童的大肠平均总转运时间中所占百分比分别为33±4%和28±3%（p=无显著性差异）；39±4%和32±4%（p=无显著性差异）；以及28±4%和41±4%（p<0.05），这表明儿童的直肠乙状结肠区域存在相对停滞。这些生理差异可能对疾病状态有影响。
