Summary
Three-dimensional printing (3DP) hepatic models accurately represent patient anatomy for surgical planning and education. While useful for understanding complex cases, 3DP models did not directly improve surgical outcomes in this study.
Area of Science:
- Hepatobiliary Surgery
- Medical Imaging
- Anatomical Modeling
Background:
- Hepatobiliary resections are complex due to intricate liver anatomy.
- Three-dimensional printing (3DP) offers patient-specific anatomical models, enhancing visualization.
Purpose of the Study:
- To validate the accuracy of 3DP models derived from imaging data.
- To assess the utility of 3DP models in hepatobiliary surgery education, patient communication, and surgical planning.
Main Methods:
- A multicenter study involving 35 patients with complex hepatobiliary tumors.
- Comparison of 3DP models with CT/MRI and surgical pathology data.
- Evaluation of model accuracy using vascular measurements, Dice Similarity Coefficient, and Bland-Altman plots.
Main Results:
- 3DP models showed high similarity to CT/MRI in vascular measurements (0.22 ± 1.8 mm) and tumor-vessel distances (0.31 ± 0.24 mm).
- Excellent agreement was found between 3DP models and surgical specimens for resection margin distances (1.15 ± 1.52 mm).
- 3DP models demonstrated a higher success rate in educational settings compared to traditional imaging (P=0.01).
Conclusions:
- 3DP hepatic models correlate well with imaging and surgical findings.
- These models are valuable tools for surgical education, patient understanding, and pre-operative planning.
- Current evidence suggests 3DP models aid planning but do not directly alter surgical outcomes.
