Description
Purpose This study was designed to introduce our novel technique of percutaneous single catheter placement into the hilar bile ducts strictures while fulfilling the purpose of bilateral biliary drainage and stenting. We investigated the efficacy and safety of the technique for the treatment of hilar nonanastomotic biliary strictures. Methods Ten patients who were post-orthotopic liver transplantation between July 2000 and July 2010 were enrolled in this study. Percutaneous Y-configured singlecatheter stenting for bilateral bile ducts combined with balloon dilation was designed as the main treatment approach. Technical success rate, clinical indicators, complications, and recurrent rate were analyzed. Results Technical success rate was 100%. Nine of the ten patients had biochemical normalization, cholangiographic improvement, and clinical symptoms relief. None of them experienced recurrence in a median follow-up of 26 months after completion of therapy and removal of all catheters. Complications were minor and limited to two patients. The one treatment failure underwent a second liver transplantation but died of multiple system organ failure. Conclusions Percutaneous transhepatic Y-configured single-catheter stenting into the hilar bile ducts is technically feasible. The preliminary trial of this technique combined with traditional PTCD or choledochoscopy for the treatment of hilar biliary strictures after orthotopic liver transplantation appeared to be effective and safe. Yet, further investigation is needed.
