A member asked:
When evaluating an abdominal xray, how can you tell if the large bowel is dilated? is it based solely on the size/circumference of the bowel?
A doctor has provided 1 answer
Yes: The upper limit of normal diameter of the bowel is generally accepted as 3cm for the small bowel, 6cm for the colon and 9cm for the cecum (3/6/9 rule). Hard numbers are less commonly used than a determination based on experience though.
