Abstract
OBJECTIVES
Gastric resection may predispose gallstone formation. However, the
mechanism has not been clearly understood. To evaluate the relationship between
gastric resection and gallstone formation, we compared gallbladder(GB) motility
in gastrectomized patients and control subjects. METHODS: We compared the GB
volume and ejection fraction of the 46 gastrectomized patients with 37 healthy
controls using real time ultrasonography. RESULTS: GB volume increased
significantly in the gastrectomized group in fasting (30.2 13.9 ml). The GB
volume after a fatty meal was greater in the gastrectomized group (12.6 6.4
ml) than in the control group (4.3 3.3 ml) (p +ADw- 0.01). A significant
reduction of ejection fraction was found in gastrectomized patients (56.9
13.0+ACU-) in comparison with the control group (75.5 16.1+ACU-) (p +ADw- 0.01). The GB
ejection fraction had a poor correlation to the postoperative period (r +AD0-
0.232). CONCLUSION: A gastrectomy appears to be a risk factor of GB dysmotility,
which may play a major role in gallstone formation in gastrectomized patients.
