Projectional radiography ("X-ray") of the abdomen and pelvis:

In children

Colon diameters

Leech score

Areas used for the Leech system of constipation grading.

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]

In adults
