产后胆囊排空功能变化与胆囊结石形成的关系

The relationship between the postpartum change of gallbladder emptying function and the formation of gallbladder gallstone

对48例产妇和20例正常未婚女性的胆囊大小、排空功能和胆囊结石影像学进行了对比研究。结果:(1)两组空腹胆囊大小分别为11.6±2.9cm^2和12.9±2.7cm^2,P>0.05,(2)两组胆囊脂餐后60分钟排空率分别为52.8±18.0%和55.1±12.4%,P>0.05。(3)产后组未见胆囊胆汁淤滞与胆石形成影像。作者认为:妊娠期胆囊增大、排空迟滞、胆汁淤滞是一种暂时性变化,不会因此而诱发胆囊结石的形成。

The comparison of maximal longitudinal section and emptying function of gallbladder was studied between postpartum and control groups.The results showed that the maximal longitudinal section of gallbladder in postpartum group(12.9±2.7cm^2)was not significantly larger than that in control one(11.6±2.9cm^2).The difference of emptying function of gallbladder after fatty meal was not obvious in statistics between post- partum(52.8+18.0%)and control group(55.1±12.4%).No evidence of gallbladder gallstone or bile stasis was found.The authors considered that the enlargement of gallbladder,the reduction of emptying function and bile stasis during pregnancy were temporary.All of these changes would soon return to normal once the pregnancy ended.The changes induced by pregnancy was not a cause in the formation of gallbladder gallstone.
