Value of 3-D visualization technique in the diagnosis and treatment of iatrogenic bile duct injury        WANG Jian. Department of Pancreaticobiliary Surgery, Renji Hospital, School of Medicine, Shanghai Jiaotong University, Shanghai 200127, China
Abstract    Repairing of iatrogenic biliary stricture is a challenge in the field of biliary surgery due to the complexity and variability of the hilar anatomy，the diversity of injury forms and types and the difficulty of repair technique. Comprehensive preoperative assessment，especially imaging evaluation，is a prerequisite for successful repairing. 3-D visualization technology can be used to evaluate the confluence and spatial conformation of hepatic portal vasculature intuitively，stereoscopically and comprehensively.It can also be used to quantitatively assess the position of bile duct stenosis，hepatic portal depth and hepatic portal rotation angel，and measure the volume of each segment of liver to determine whether there is hepatic atrophy.By rotation，superposition and removal of intrahepatic vascular structure，surgeons can formulate reasonable surgical paths，forecast the operation risk，plan operation scheme to improve the operation safety and efficacy，avoid secondary injury caused by blind surgical exploration.

Key words: 3-D visualization technique, iatrogenic bile duct injury
