Abstract    Objective    To analyze risk factors of bile duct injuries caused by laparoscopic cholecystectomy. Methods The clinical data of 4531 cases of laparoscopic cholecystectomy between October 1999 and December 2010 in People’s Hospital of Liuyang City were analyzed retrospectively. All influential factors were checked in chi square, and independent risk factors about bile duct injuries were analyzed simultaneously. Results    Univariate analysis showed bile duct injuries were associated with gender, staging of inflammation, thickness of cholecyst wall by sonography, anatomy of Calot’s triangle and surgical experience (P＜0.05). Anatomy of Calot’s triangle and surgical experience were independent risk factors of bile duct injuries, which was showed by multivariate unconditional Logistic regression analysis (P＜0.05). Conclusion    Anatomy of Calot’s triangle and surgical experience are independent risk factors of bile duct injuries.
