Projectional radiography ("X-ray") of the abdomen and pelvis:
In children
The diameters of different segments of the large intestine can be compared to the width of lumbar vertebra 2 for more consistent reference ranges on abdominal x-rays.[1]
Ratios of large intestinal segments compared to lumbar vertebra 2, as 75th percentile, meaning that 25% of children normally have a ratio higher than this.[1]
For children, the degree of constipation may be scored by the Leech or the Barr systems:
- The Leech system assigns a score of 0 to 5 based on the amount of feces:[2]
- 0: no visible feces
- 1: scanty feces visible
- 2: mild fecal loading
- 3: moderate fecal loading
- 4: severe fecal loading
- 5: severe fecal loading with bowel dilatation
- These score are assigned separately for the right colon, the left colon and the rectosigmoid colon, resulting in a maximum score of 15. A Leech score of 9 or greater is regarded as positive for constipation.[2]
- The Barr system rates both the amount and consistency of the faeces, and assigns a score separately for the ascending colon, transverse colon, descending colon and rectum. Its maximum score is 22, and a score of 10 or greater is regarded as positive for constipation.[3]
