Project goal is to evaluate utility of personalized 3D printed models in preoperative planning and performing laparoscopic liver resections. Models will be developed with unique, low-cost approach. Project will consist of three overlapping modules/stages evaluating:~Accuracy of 3D printed liver models compared to computed tomography and standard surface or volume rendering~Whether 3D printed utilized in planning surgery affects the decision making regarding the surgical plan~Whether 3D printed models utilized in planning and navigating laparoscopic resections affect perioperative outcomes~Methodology of developing 3D models is described elsewhere. Printed models will be delivered to surgical team at least 5 days prior to the resection. Surgery will be performed in both arms according to the department's procedures and surgical oncology guidelines.
