摘　　要：背景:B超检查是测定胆囊排空率的常用方法之一,目前胆囊排空率餐后测定时间选择的差异较大并影响到该方法的应用,探讨较理想的餐后测定时间将有益于临床实践。目的:探讨B超测定胆囊排空率的餐后测定时间。方法:对13例健康志愿者于空腹以及流质脂餐后30、60、90和120 min时用B超测定胆囊容积,计算并比较各时点的胆囊排空率。结果:13例健康志愿者餐后30 min时的胆囊排空率为55.0％±13.2％,与60、90和120 min时的排空率相比无显著差异（P>0.05）,但餐后30 min时数据的个体间变异系数最小。结论:B超测定胆囊排空率,餐后30 min时的测定值波动范围相对较小,能较客观地反映胆囊动力状态。Background: Ultrasonography is one of the common methods of measuring gallbladder emptying. The various times selected as postprandial phase of gallbladder emptying affect the application of this method. The selection of optimum postprandial phase would be benefit to clinical practice. Aims: To investigate the postprandial phase of gallbladder emptying measured by ultrasonography. Methods: The gallbladder volumes in 13 healthy volunteers were measured by ultrasonography before breakfast and at 30, 60, 90 and 120 min postprandially after a liquid-fat meal. The gallbladder emptying rates in different postprandial phases were calculated and compared. Results: The gallbladder emptying rates in 13 healthy volunteers at 30 min after meal was 55.0%±13.2%, which was not statistically different when compared with those at 60, 90 and 120 min (P>0.05). However, the coefficient of variation (CV) for individual gallbladder emptying rate at 30 min postprandially was smallest. Conclusions: The measurement of gallbladder emptying rates by ultrasonography at 30 min after meal can objectively reflect the motility status of gallbladder with limited fluctuation.
