[Is there a "hypertonic gallbladder" in hyperthyroidism? Initial results]

In five female patients with hyperthyroidism the motor function of the gallbladder was examined using sonography. After therapy, the fasting volume and the volume resulting 30 minutes after cholagogue showed a tendency to increase (p approximately 0.15, p approximately 0.25, respectively). The emptied volume and the rate of emptying showed no changes. Although our findings failed to attain statistical significance they suggest an influence on the motor function of the gallbladder resembling a "hypertonic gallbladder". It will be necessary to study a significantly greater number of patients to confirm this thesis.
