Abstract    For diagnosis of patients with recurrent intrahepatic calculi, 3D and visible simulation techniques  have more significant advantages than routine preoperational imaging examinations, because  they are able to provide a more intuitive and comprehensive displaying of strictures in the bile duct , variations of biliary duct or blood vessel  and  residual lesions near the previous operation area. Moreover, three-dimensional reconstruction and visible simulation techniques have unique value in optimizing repeated operation plans for patients with recurrent intrahepatic calculi through designing the operational  incision and operational path,facilitating the understanding of the mechanism of stone formation or recurrence, guiding hepatoectomy and choledochojejunostomy and the optimization of surgical procedures.
