Outline of Final Research Achievements

For the adrenal gland neuroblastoma, a three-dimensional organ model was created from a preoperative photographed CT image using a 3D printer. Using a resin that can be inserted into a trocar, a body was created, and it was used for simulation of tumor position in laparoscopic view, and examination of the best position of the trocar. We also modeled adrenal gland and liver model for liver metastasis cases of neuroblastoma and conducted surgical simulation.
For hepatoblastoma, the same pediatric malignant tumor as neuroblastoma, a three-dimensional organ model was created from preoperative CT images. We confirmed the positional relationship between the portal vein and the hepatic vein and the position of the tumor, and simulated the resection line before surgery. We found the utility such as being able to more easily understand the anatomical information.
