Percutaneous biliary intervention is widely accepted as an effective and safe treatment for various types of bile duct diseases. We present the case of a 44-year-old woman who developed bile leakage after a living-donor liver transplantation for locally advanced cholangiocarcinoma. A percutaneous drainage tube was placed in the segment 8 bile duct via the blind end of the jejunum. However, the bile leakage was unchanged. Bile leakage from the right posterior hepatic duct was suspected. Using a dual lumen microcatheter, a percutaneous drainage tube was placed in the segment 7 bile duct via the blind end of the jejunum, which reduced the bile leakage. These results suggest that a dual lumen microcatheter is a valuable tool for navigating the biliary tree during difficult percutaneous biliary interventions.
