Résumé : Transit times through the whole colon and its segments were measured in 10 healthy children and 14 children suffering constipation secondary to myelomenin-gocele. The subjects ingested radio-opaque markers on three successive days, and on the fourth a plain abdominal roentgenogram was taken using fast film. In the healthy children, total colonic transit time (mean ± SD) was 37.8 ± 6.2 h, with segmental times of 10.8 ± 3.5 h for the right colon, 12.2 ± 2.7 h for the left, and 14.7 ± 2.1 h for the rectosigmoid; upper normal limits of 17.8 h for the right colon, 17.6 h for the left, 19.1 h for the rectosigmoid, and 50.2 h for the total colonic transit time were established. In the constipated children, the total transit time was 59.9 ± 5.4 h, with segmental times of 15.9 ± 2.3 h for the right colon, 18.9 ± 2.3 h for the left, and 25.0 ± 2.6 h for the rectosigmoid. The technique described is simple, is easy to use in clinical practice, and involves a lower radiation dose than other methods. It may prove useful for measurement of colonic transit time in suitable patients. © 1991 Raven Press, Ltd., New York.
