Abstract: [Abstract] Objective: To analyze the cause of bile duct injury, and find a way to prevent bile duct injury ,so as to promote the application of LC.Methods: To study bile duct injury of 29 LC cases which were treated in Affiliated Hospital of Zunyi Medical College from september 2003 to april 2010 , and in order to find way to prevent bile duct injury during LC . Results: LC bile duct injury was an anccident by various levels physicians and at various levels hospitals.The accident mostly been done by the beginners,and mostly happpend in primary hospital.It always been found after operation. The most injury was bile duct transection . Anatomical variations and triangle inflammatory adhesions always be the cause which led to bile duct injury.Conclusion: Bile duct injury closely relate to biliary anatomical variations, biliary pathological factors and the clinical experience and surgical skills of doctors. To understand the physiological characteristics of bile duct tissue and the technical characteristics of LC will help us to prevention bile duct injury during LC. In ordor to treate enything that may lead to bile duct injury reasonablely during LC , surgeon should improve his Clinical quality and increase awareness of bile duct injury and change the surgical technique timely laparotomy.

摘要： 目的 分析腹腔镜胆囊切除术（laparoscopic cholecystectomy, LC）胆管损伤发生的原因，预防胆道损伤，促进LC普级应用。方法 对遵义医学院附属医院肝胆外科2003年9月～2010年4月收治的29例胆道损伤病例进行研究，分析LC发生胆管损伤的原因，研究预防胆管损伤的措施。结果 LC胆道损伤在各级医院，各级医师都有发生，而以基层医院和初学者发生率最高， 并且多在手术后发现。损伤性质中以胆管横伤最常见，而解剖变异和三角区炎症粘连是LC胆管损伤最常见因素。结论 胆道解剖变异、病理因素以及医生的临床经验和手术技能与胆道损伤关系密切，了解胆道组织生理构建、LC技术特点有利于预防胆道损伤。手术医师提高综合素质，合理处理可能导致LC胆道损伤的不利因素，提高对胆管损伤的警觉性，适时中转。
