摘　　要：目的探讨三维超声评估胆囊功能及胆囊胆汁动力时相的临床意义。方法利用三维超声对50例正常体检者(正常组)和50例胆囊结石患者(胆石组)进行脂餐试验,记录餐前、餐后每隔10 min的胆囊容积,共计380 min,计算胆囊最大收缩率(GBEF_(max))和最大收缩时间(Tmax),并绘制胆囊容积变化曲线图。结果正常组餐前胆囊容积为(16.75±7.14)mL,餐后90 min胆囊容积最小为(1.90±0.98)mL,GBEF_(max)为(88.61±10.39)%,Tmax为(90.34±12.36)min,360 min胆囊容积恢复到餐前水平。与正常组比较,胆石组餐前胆囊体积(19.06±6.93)mL明显增大(P<0.05),GBEF_(max)(67.27±7.26)%明显降低(P<0.05),Tmax(110.85±10.33)min明显延长,餐后约360 min胆囊容积恢复到餐前水平。依据胆囊胆汁动力相变化,胆囊胆汁排出相为餐后0~90 min,胆囊胆汁充盈相为餐后90~360 min,胆囊胆汁浓缩相为餐后360 min。结论三维超声等影像学只需检测餐前和餐后90 min胆囊容积即可达到评估胆囊功能,胆囊胆汁动力时相的变化可能更全面体现胆囊功能,对临床手术方式及时机的选择有较高实用价值。Objective To evaluate the clinical significance of gallbladder function and dynamic phase ofgallbladder in three-dimensional ultrasonography.Methods A total of50healthy subjects and50patients withcholecystitis were selected to analyze the gallbladder contraction rate(GBEFmax),maximal contraction time(Tmax),and coordinates of the gallbladder volume was drew by the h-fat meal experiment.Results In healthysubjects group,the volume of gallbladder was(16.75±7.14)mL before h-fat meal,and the minimum volume was(1.90±0.98)mL after h-fat meal90min,GBEFmax was(88.61±10.39)%,and the volume of gallbladder was recoveredto normal after h-fat meal360min.Compared with healthy subjects group,gallbladder volume before h-fatmeal in the patients group was increased significantly(P<0.05),GBEFmax was decreased significantly(P<0.05),Tmax was extended significantly(P<0.01),but the gallbladder movement cycles were similar(P>0.05).ConclusionThe volume of gallbladder which measured before h-fat meal and after h-fat meal90min can evaluate thegallbladder function.
