超声检查对胎儿胆囊结石的诊断价值

The clinical value of ultrasonography in the diagnosis of fetal gallstones

目的 探讨超声检查对胎儿胆囊结石中的诊断价值,同时探讨胎儿胆结石的发生机制.方法 对21 020例孕妇行产前常规超声检查,并进行总结分析.结果 21 020例孕妇中,检出疑似胎儿胆囊结石15例,检出率为7.14/10 000.其中男性10例,女性为5例.11例与胎龄大小接近,2例大于实际胎龄,2例小于实际胎龄.胎儿胆囊内强回声呈颗粒状、团块状、条带状,偶有后方回声增强.15例疑似胎儿胆囊结石患儿中12例于出生2周后消失,另外3例于出生半年后消失.结论 超声检查对胎儿胆囊结石的诊断有重要的价值.胎儿胆囊结石的形成机制应为胎儿胆总管反流的肠内容物形成的.

Objective To explore the clinical value of ultrasound in the diagnosis of fetal gallbladder stones and the mechanism of fetus gallstones.Methods 21 020 pregnant women were taken routine ultrasound,and the results were analyzed.Results Of 21 020 pregnant women,15 cases were suspected fetal gallbladder stones,including 10 males,5 females.The detection rate was 7.14/10 000.11 cases were close to gestational age,2 cases were greater than the actual gestational age and 2 cases were smaller than the actual gestational age.The echogenic in the fetal gallbladder showed granular,lumpy,banded.Occasionally,posterior echo enhancement was found rear.In 15 cases of suspected fetal gallbladder stones,12 cases disappeared two weeks after birth and the other 3 cases disappeared in the six months after the birth.Conclusion Ultrasound can confirm diagnosis of fetal gallbladder.There is important value in the diagnosis of suspected fetal gallbladder stones.The mechanism for echogenic might be fetal common bile duct reflux of intestinal contents.
