　　Professor Dong’s research interests include theories and technologies in modern hepatobiliary surgery, liver transplantation and the management of complex biliary diseases. He was first worldwide to propose the concept of “Precision Surgery”, and has been endeavoring to establish the surgical paradigm and technological system of hepatobiliary surgery ever since. By innovatively applying precision surgery to intrahepatic bile duct diseases, including intrahepatic stone, bile duct dilatation, and hilar cholangiocarcinoma, Professor Dong has successfully changed the treatment pattern from symptom alleviation to complete cure. He has also refined the strategy of liver transplantation using the paradigm of precision surgery, largely improving the treatment of end-stage hepatobiliary diseases. In extracorporeal liver resection and auto-transplantation, he and his team have optimized and standardized the procedure, and have demonstrated success in applying it to the treatment of end-stage hepatic echinococcosis. These results have a major impact on and have changed the practice of hepatobiliary surgery worldwide.
