The aim of this study was to evaluate a visible simulation surgery technique for choosing the best surgical plan in patients with intrahepatic calculi.
A medical image processing system was used to process computed tomography (CT) scanning data collected from four cases of intrahepatic calculi. Models of liver and bile ducts in standard template library format were processed by a free-form modeling system and reconstructed three-dimensionally. Accurate digital information about the bile duct system, lesions, calculi distribution, and adjacent organs from all directions, multiple angles, and multi-strata were used to choose the best surgical plan. Then, visible simulation surgery was performed with simulation operation software.
Three-dimensionally reconstructed models provide clarity with strong relief perception and a user-friendly interface. Visible simulation surgery performed based on three-dimensionally reconstructed models led to optimal operation planning.
Visible simulation surgery is more objective and complete than routine preoperative examinations to choose the best operation plan for intrahepatic calculi.
