【Abstract】Objective To observe the bacteria in cholesterol stones by electronic microscope and to explore the role of bacteria in the stone formation.Methods Twelve patients with cholelithiasis underwent operations (male 6, female 6, average age 54.6 years） with cholecystolithiasis 5, extrahepatic and intrahepatic bile duct stone 1, common bile duct stone combining with gallstone 6. The cholesterol stones were observed by electronic microscope.Results There were bacterial structures in the cholesterol stones and cholesterol crystals.Conclusion There are bacteria in the core and peripheral of cholesterol stones, which suggests that bacteria may play an initial role in the formation of cholesterol stones.
【摘要】目的 探讨纤维胆道镜对肝胆管狭窄的诊治价值。 方法 对45例肝胆管狭窄患者进行纤维胆道镜诊治，总结分析其方法的优越性。根据不同狭窄类型，治疗采取活检钳撕破狭窄膜或镜身扩张法、球囊扩张加支架支撑法。 结果 所有病例均成功治愈，无一例出现明显并发症。 结论 纤维胆道镜治疗胆管狭窄具有微创、安全、有效及方便等优点，是治疗肝胆管狭窄的有效手段。
【Abstract】Objective To discuss the application of endoscopic diagnosis and treatment of biliary stone with choledochofiberscope after orthotopic liver transplantation.Methods Five patients with repeated infection of bile duct and obstructive jaundice were treated with choledochofiberscope through T tube sinus, combining with the plasma shock wave lithotripsy, the eyewinker clam and the basket extraction. Results We could efficiently extract the biliary tract stone through choledochofiberscope combining with plasma shock wave lithotripsy, eyewinker clam and basket extraction; and observe the healing appearance, and blood circulation of the biliary tract. Conclusion The choledochofiberscope can be used to diagnose and treat biliary tract stone of orthotopic liver transplantation. The choledochofiberscope and T tube will be important in diagnosis and treatment of biliary tract stone following orthotopic liver transplantation.
