AIM:It is difficult to differentiate gallstone dyspepsia and functional dyspepsia by clinical symptoms and signs. We hypothesized that gallstone dyspepsia was related to abnormal gallbladder motility. We aimed to differentiate gallstone dyspepsia from functional dyspepsia by measuring gallbladder motility.METHODS: We measured gallbladder volume changes in response to gastric distension (saline 500mL) and fatty meal in 10normal volunteers (controls) and 62 patients with gallstones and dyspepsia before cholecystectomy. Forty cholecystectomized patients were symptom free or had improvement (group I), while the remaining 22 patients had persistent dyspepsia (group Ⅱ). Gallbladder volume change and ejection fraction were analyzed and compared among the three groups.RESULTS:In group I, there were significant decreases in gallbladder volumes 5-25 rain after gastric distension,compared to fasting volumes. Compared to normal volunteers and group Ⅱ, group I had significantly decreased gallbladder volumes 10-20min after drinking 500mL of normal saline and 10 to 50min after eating fatty meal.CONCLUSION:Our results support the hypothesis that increased gallbladder contraction after gastric distension or fatty meal may be related to dyspeptic symptoms in uncomplicated gallstone disease. These findings may be useful in differentiating functional dyspepsia from gallstone dyspepsia, patients with the latter disease may benefit from laparoscopic cholecystectomy.
