Sponsor's own description

Background: Primary aspect of hepatic navigation surgery is the identification of source vascular details to preserve healthy liver which has a vascularity anatomy quite challenging for the young surgeons. The purpose was to determine whether three-dimensional (3D) vascular pattern models of preoperative computed tomography images will assist resident-level trainees for hepatic surgery.

Methods: This study was based on the perception of residents who were presented with 5 different hepatic source vascular pattern and required to compare their perception level of CT, and 1:1 models in terms of importance of variability, differential of patterns and preoperative planning.

Results: All subspecialties agree that models provided better understanding of vascular source and improved preplanning. Five stations provided qualitative assessment with results showing the usefulness of porta-celiac models when used as anatomical tools in preplanning (p=0.04), simulation of interventional procedures (p=0.02), surgical education (p=0.01). None of the cases a scored less than 8.5. Responses related to understanding variations were significantly higher in the perception of the 3D model in all cases, furthermore 3D models were more useful for seniors in more complex cases 3 \& 5. Some open-ended answers: "The 3D model can completely change the operation plan" One the major factors for anatomical resection of liver transplantation is the positional relationship between the hepatic arteries and the portal veins. Conclusions: The plastic-like material presenting the hepatic vascularity enables the visualization of the origin, pattern, shape, and angle of the branches with appropriate spatial perception thus making the well-structured.
