胃次全切除术后胆囊排空功能的超声研究

摘要

24例胃次全切除术患者眼自制胆囊标准试餐(Lundh试餐:脂肪18.0g、蛋白质15.0g、碳水化合物45.0g),行B超检查,其空腹胆囊B超容积为29.22±15.35ml,餐后最小残余容积为13.69±7.96ml,最大收缩率为52.26±17.63%,与正常对照组差异显著.提示:胃次全切除术后.胆囊排生功能呈多指标性减弱.%This article presents the sonographic changes of gallbladder motility functions in 24 patients after gastrectomy.All patients used with Lundh Test Meal(fat 18.0g,protein 15.0g,eatbohydrate 45.0g).The results of investigation suggest:1)the fasting gallbladder volume is 29.22±gallbladder contration is 52.26±17.63%.It is concluded that many indexes of gallbladder motility functions wear decrease in patients after gastrectomy.
