采用Ｂ超对胃切除组９４例与健康对照组８６例胆囊收缩功能和胆囊结石发生情况进行对照观察。结果发现胃切除术后胆囊收缩功能不良者胃切除组６８例（７２．３％），对照组１７例（１９．８％），胆囊结石胃切除组３２例（３４．０％），对照组４例（４．７％）。两组比较差异有显著性（Ｐ＜０．０１）。说明胃切除术后胆囊收缩功能下降及胆汁瘀积是胆囊结石形成的两大要素 B-ultrasound on the gastrectomy group of 94 patients and healthy control group of 86 cases of gallbladder contractility and gallbladder stones were controlled.
