Since abnormal gallbladder emptying may be a contributing factor in the development of
gallstone disease, we determined fasting gallbladder volume and postprandial contraction
in 20 gallstone patients and 20 normal subjects with the aid of ultrasonography. Moreover,
basal plasma cholecystokinin levels and postprandial cholecystokinin (CCK) release were
determined. Gallstone patients were divided into strong contractors (13 pts) and weak
contractors (below 95% confidence interval for AUC contraction in% during 90 min: 7 pts) …
