“…Thirdly, Equation 7is tested in the design of a 3D Voronoi structure of a kidney cancer tumour, which can be used to increase a patient's understanding of a complex ontological surgical procedure or provide a surgical team with an in-depth model of the impending operation 26,27 . Saribudak et al 13 designed a 2D Voronoi model from a kidney cancer tumour with ε = 35.0 mm (measured using hematoxylin-eosin staining) 13 .…”

“…The emergence of additive manufacturing has extended the application of Voronoi tessellation from mere analysis to the generation of 3D scaffolds, i.e., Voronoi structures with mesh wrapped around the wireframes. Voronoi scaffolds have been 3D printed as supports for hollow objects 19 , interlocking architecture 20 , optimal lightweight structures [21][22][23] , patient specific bone scaffolds 24,25 , for surgical practice 26 , for patient education of upcoming procedures 27 , regenerative medicine and wound healing techniques 28 , implantable drug delivery 29 and T-cell culturing environments 14 .…”

“…In this way, they are widely used in the biomedical field in a wide range of applications, such as breast implants [ 29 ], prostheses [ 30 ], hypertrophic burn scars [ 31 ] or phantoms [ 32 ]. The latter application can be performed with hydrogels, although, as mentioned before, they are not very consistent, and their lifespan is very short, not enough to be used for purposes apart from surgical planning, such as patient education [ 33 ] or for medical school interns.…”

Background: Pre-surgical simulation-based training with three-dimensional (3D) models has been intensively developed in complex surgeries in recent years. This is also the case in liver surgery, although with fewer reported examples. The simulation-based training with 3D models represents an alternative to current surgical simulation methods based on animal or ex vivo models or virtual reality (VR), showing reported advantages, which makes the development of realistic 3D-printed models an option. This work presents an innovative, low-cost approach for producing patient-specific 3D anatomical models for hands-on simulation and training. Methods: The article reports three paediatric cases presenting complex liver tumours that were transferred to a major paediatric referral centre for treatment: hepatoblastoma, hepatic hamartoma and biliary tract rhabdomyosarcoma. The complete process of the additively manufactured liver tumour simulators is described, and the different steps for the correct development of each case are explained: (1) medical image acquisition; (2) segmentation; (3) 3D printing; (4) quality control/validation; and (5) cost. A digital workflow for liver cancer surgical planning is proposed. Results: Three hepatic surgeries were planned, with 3D simulators built using 3D printing and silicone moulding techniques. The 3D physical models showed highly accurate replications of the actual condition. Additionally, they proved to be more cost-effective in comparison with other models. Conclusions: It is demonstrated that it is possible to manufacture accurate and cost-effective 3D-printed soft surgical planning simulators for treating liver cancer. The 3D models allowed for proper pre-surgical planning and simulation training in the three cases reported, making it a valuable aid for surgeons.
