背景原发性肝内胆管结石常合并胆道感染。本研究旨在探讨肝内胆管结石与胆道感染的关系。方法对35例胆汁标本和30例结石标本进行细菌培养，并对12例结石标本进行扫描电镜（SEM）和透射电镜（TEM）观察。结果94.2%的胆汁标本和96.7%的结石标本细菌培养阳性。扫描电镜和透射电镜下可见结石内有细菌。结论结石内细菌与胆道感染有关。
BACKGROUND Primary intrahepatic cholelithiasis is usually combined with biliary tract infection. This research was undertaken to investigate the relationship between intrahepatic stones and biliary tract infection. METHODS Thirty-five bile samples and 30 stones specimens were cultured for bacteria and 12 stones specimens were examined with a scan electron microscope (SEM) or a transmission electron microscope (TEM). RESULT 94.2% bile samples and 96.7% stones specimens were positive in bacteria culture. Bacteria were found in stones under SEM and TEM. CONCLUSION Bacteria in stones are associated with the infection of the biliary tract.
