Gallbladder kinetics in the black African subject with and without cholelithiasis. An ultrasonographic study
2004
PURPOSE: Gallbladder hypomotility could play a significant role in the process of lithogenesis, but this role has yet to be defined in black African populations. This role was assessed by measuring gallbladder emptying after stimulation by a fat meal in a group of black African subjects with and without cholelithiasis. MATERIALS AND METHODS: Fifteen subjects with cholelithiasis and thirty controls divided in two pools were studied. Gallbladder emptying was stimulated by fat meals of 610 and 740 Kcal, and was measured with ultrasound for a period of 120 min. RESULTS: The mean fasting gallbladder Volume of the subjects with lithiasis was significantly superior to that of the controls. Compared to what has been previously published in Caucasian subjects, gallbladder emptying was generally more rapid in our study. Further more, gallbladder emptying was significantly better in the control group than in the group of subjects with cholelithiasis. Two groups of subjects with cholelithiasis were isolated. The first group had poor gallbladder emptying and normal fasting gallbladder Volume; the second had normal gallbladder emptying but significantly increased fasting gallbladder Volume. CONCLUSION: Impaired gallbladder emptying and/or increased fasting gallbladder Volume probably play a role in lithogenesis. Hypomotility seems to play a significant role only for those subjects with normal fasting gallbladder Volume.
