ABSTRACT
The digital intelligent medical technology such as three dimensional visualization, three dimensional printing,enhanced/virtual reality technology, indocyanine green molecular imaging are widely used in the clinical diagnosis and treatment of hepatobiliary and pancreatic diseases and showed a booming trend. Perihepatic hilar biliary tract diseases with complex anatomical structure, special physiological pathology character and lower efficiency of diagnosis and treatment are the major and difficult disease in the field of surgery. Efficient preoperative evaluation is the key to improve the efficiency of diagnosis and treatment. The digital intelligent medical technology can be used to obtain the comprehensive, individualized image diagnostic information,and comprehensive analysis the anatomy relations of the hepatic artery, portal vein, bile duct and lesions, and quantitatively measure the liver volume, formulate the reasonable operation scheme, determine the best approach of surgery, predict intraoperative injury risk and improve the surgical treatment effect.
