    Abstract:
    OBJECTIVE: To investigate the value of percutaneous balloon dilation and percutaneous transhepatic cholangial drainage (PTCD) catheter maintenance in the treatment of benign biliary strictures. METHODS: The clinical data of 21 patients with benign biliary strictures at Peking Union Medical College Hospital from June 2005 to June 2011 were retrospectively studied, in which 12 patients in severe stricture (stenosis > 70%) were treated with percutaneous balloon dilation and PTCD catheter placed across the stricture, while another 9 patients in median stricture (stenosis < 70%) were only treated with PTCD catheter maintenance. RESULTS: Of the 12 patients underwent balloon dilation and 6 - 12 months (median: 9 months) of PTCD catheter placement, 11 patients had the catheter successfully removed. In the follow-up of 6 - 24 months (median: 10 months), patency of bile duct was preserved in 9 of 11 patients, and recurrent stenosis was seen in 2 patients. A severe complication with biliary artery branch rupture and massive hemobilia was seen in 1 patient during balloon dilation. Of the 9 patients only treated with 1 - 12 months (median: 6 months) of PTCD catheter placement, 7 patients had the catheter successfully removed. In the follow-up of 5 - 18 months (median: 8 months), patency of bile duct was preserved in 5 of 7 patients, and recurrent stenosis was seen in 2 patients. No severe complication occurred. CONCLUSIONS: When endoscopy therapy is failed or the patient can't undergo endoscopy therapy, the percutaneous balloon dilation and PTCD catheter maintenance method is an effective alternative therapeutic approach in the treatment of benign biliary strictures. The moderate benign biliary stricture may be effectively treated only by the PTCD catheter maintenance method.
