[Morphometric findings of the healthy pediatric gallbladder in ultrasound].
OBJECTIVE
Ultrasonographic determination of gallbladder wall thickness, volume and excretion in children.


METHODS
In 76 children (1-16 years) we determined the volume of the fasting and stimulated gallbladder by the ellipsoid formula (length X width X depth X 0.523). We also measured the gallbladder wall thickness. Stimulation was performed with a standardised breakfast.


RESULTS
We always measured the gallbladder wall thickness 3 mm or less and did not find a difference between fasting and stimulation. There was no correlation between gallbladder wall thickness and status of contraction. The healthy gallbladder should excrete at least 25% of the fasting volume within 1 hour.


CONCLUSIONS
Ultrasound is a suitable method to determine the excretion of the gallbladder. In children standardised meals can be used as stimulus instead of commercial stimulating meals.
