- Abstract
Introduction: Liver anatomy has always been a challenge due to its complexity and variability. In recent years, lower costs has allowed the generation of individualized 3D models for each patient, which can facilitate the surgical approach to liver lesions. The main objective was to determine usefulness of preope)rative 3D modeling for surgical planning in patients with liver lesions. Methods: Quasi-experimental before-after study. 19 cases were included in which surgery was planned using a 3D printed model (13 bilobar hepatectomies, 3 of them with vascular involvement, and 6 unilobar hepatectomies, 1 of them with vascular involvement), and another 19 cases whose planning was carried out without a 3D printed model (7 bilobar segmental hepatic resections and 12 unilobar segmental resections. None of these cases had vascular involvement). Results: A significant difference in mean lesion count was observed, higher in the group of cases when performing the Wilcoxon test (p < 0.001), and a higher number of cases with vascular involvement in the same group when performing the Pearson chi-square test (p = 0.008). The rest of the variables did not show statistically significant differences. Despite this, mortality was reduced to 0 when 3D printed models were used. Conclusion: 3D printing allows for more precise planning of complex liver surgeries, helps with the inclusion and exclusion of patients for surgery, reduces operating room time, postoperative hospitalization, and surgical complications.
