Abstract: Digital medical technology pioneered the three dimensional (3D) era of the surgery. The 3D reconstruction and visualization technology made a breakthrough of the bottleneck of clinical diagnosis and therapy of the biliary surgery, and are widely used for the treatment of  biliary disease such as hepatolithiasis and hilar cholangiocarcinoma, and achieved digital anatomy, procedural diagnosis and visualized surgery, just as provide a 3D X ray vision to surgeons. With the development of the digital medical technology and the wide application of 3D laparoscopy and robotic system, biliary tract surgery access to a 3D era.
