Abstract
OBJECTIVES: To assess the effect of periodic and moderate alcohol intake on gallbladder motility. METHODS: The ultrasonographic ellipsoid method was used in 21 healthy male subjects: 12 non-alcohol and 9 alcohol drinkers. The stimulus for gallbladder contraction was 165 ml of half cream milk. Gallbladder dynamics were studied for 20 minutes following the ingestion of the milk. The mean percentage change in gallbladder volume after 10 and 20 minutes gave indications of gallbladder motility. RESULTS: Moderate and periodic alcohol intake did not stimulate rapid postprandial gallbladder emptying. CONCLUSION: The protective effect of alcohol against biliary cholesterol cholelithiasis could not be due to stimulation of gallbladder emptying.
