目的应用Simpson法测量技术评价老年2型糖尿病(T2DM)对患者胆囊收缩功能的影响。方法53例老年T2DM患者(A)组和36例对照(B)组采用高脂餐试验,采集胆囊长轴切面声像图,应用改良Simpson法直接测量高脂餐前后两组胆囊的容积,并统计胆囊排空率。结果与B组相比,A组空腹胆囊的容积及脂餐后1-h胆囊残余容积明显增大(P<0.01);A组胆囊排空率明显减低(P<0.01)。结论改良Simpson法测量胆囊容积简便易行。
Objective To evaluate the effect of T2DM on the gallbladder contractility in patients with Simpson method. Methods 53 elderly T2DM patients (group A) and 36 healthy volunteers (group B) received high-fat meal test. The long-axis sonogram of gallbladder was collected. The volume of gallbladder before and after high-fat meal was measured by modified Simpson method. Gallbladder emptying rate statistics. Results Compared with group B, the volume of fasting gallbladder and the residual volume of 1-h gallbladder in group A were significantly increased (P <0.01), and the rate of gallbladder emptying in group A was significantly decreased (P <0.01). Conclusion Improved Simpson method is simple and easy to measure the volume of gallbladder.
