Abstract    Objective    To discuss the value of percutaneous interventional procedure in the treatment of iatrogenic bile duct injury.  Methods    The clinical data of 51 cases of iatrogenic bile duct injury treated with percutaneous interventional procedure initially since 2000 in Shengjing Hospital of China Medical University were analyzed retrospectively. Results    Abdominal fluid collection was found in 27 cases and then treated with percutanous drainage initially. Biliary endoprosthesis implantation was attempted in 6 cases. Intrahepatic and/or extrahepatic bile duct dilatation was found in 26 cases. Percutaneous transhepatic biliary drainage was performed in 24 cases. Balloon dilatation was attempted in 3 cases. Endoscopic biliary stenting was performed in the other 2 cases. Percutaneous drainage of abdominal fluid collection was performed in 27 cases successfully. The relief of clinical symptoms and the reduction of fluid collection were represented in all cases. Bile leak immediately disappeared in 4 cases performed biliary endoprosthesis implantation and the biliary fistula finally healed in 2 cases. Percutaneous transhepatic biliary drainage was all performed successfully in 24 cases. The bilirubin decreased significantly (t= 15.61, P<0.01) 1 week later. Balloon dilatation was performed in 3 cases successfully and the biliary obstruction was relieved immediately. However, restenosis of bile duct occurred within 24 hours in 1 case. Endoscopic biliary stenting was performed in 2 cases successfully, who both represented restenosis of bile duct 6 months later. Conclusion    Percutaneous interventional procedure has a great value in the initial treatment of iatrogenic bile duct injury.
