慢性胆囊炎与胆结石形成关系的超声研究

目的 探讨慢性胆囊炎与胆结石形成的关系.方法 慢性胆囊炎、胆结石患者及正常人各20例采用超声法进行脂餐前后胆囊容积及排空率的测定.结果 结石组较对照组脂餐前、餐后各期胆囊容积增大,排空率降低(P＜0.05).慢性胆囊炎组餐后胆容积及排空率与对照组无显著性差异(P＞0.05),但空腹容积显著增大(P＜0.05).结论 慢性胆囊炎患者存在胆囊运动功能异常,这种异常可能是胆囊结石形成的原因之一.

Ultrasound study on the relation between chronic cholecystitis and gallbladder stone formation

Objective To investigate the relation between chronic cholecystitis and gallbladder stone Formation.Methods Fasting and postprandial gallbladder motor function were measured by ultrasonography in 20 chronic cholecystitis,20 gallbladder stone patients and 20 normal persons.Results The results showed that the maximal percentage emptying of gallbladder in the gallbladder stone group were obviously reduced than that in control group(P<0.05).But the maximal percentage emptying of gallbladder postprandially in chronic cholecystitis group was not significant different from that in control group(P>0.05).The base gallbladder volume of chronic cholecystitis and gallbladder stone group were larger than that of control group(P<0.05).Conclusion This study suggests that abnormal gallbladder motility in patients with chronic cholecystitis may be the early change of gallbladder stone.
