Postprandial gall-bladder emptying in patients with gall stones.

Publication Date
  • Research Article


Gall-bladder emptying in response to a standard meal was assessed in 34 patients with radiolucent gall stones and 34 matched controls. Percentage gall-bladder emptying, derived from volume measurements made on standardised oral cholecystography, was significantly higher at 15 minutes in the patients than the controls (mean +/- SE of mean 38.0 +/- 3.7% v 28.0 +/- 3.8%). This difference was maintained at 30 and 60 minutes. It is concluded that postprandial gall-bladder emptying is increased in patients with cholesterol gall stones, and that this may be the cause of the small bile-acid pool found in these patients.
