  • Application of 3D Printing Technology in Hepatic Resection

    ObjectiveTo explore clinical value of 3D printing technology in hepatic resection. MethodsFrom March to May 2015, multidetector-row computed tomography images of 12 patients, including hepatic carcinoma in 6, hepatic hemangioma in 3, intra-and extra-hepatic bile duct stones in 3, were used for 3D hepatic reconstruction, the final segmentation data were converted to stereolithography files for 3D printing, 50%-70% scale of the full-sized liver model was fabricated by polylactic acid to be used to analyze its anatomical structure, design surgical planning, select the optimal operative route and simulate hepatic resection. Hepatic resection was performed by referring to the 3D printing model. ResultsThe hepatic resections were successful without complications by referring to the preoperative 3D printing models, the average blood loss was 340(100-1000) mL. ConclusionHepatic resection is more accurate and safe by 3D printing technology.
