Key result
Three-dimensional technologies improve preoperative planning accuracy and alter surgical decisions in up to ~35% of pancreatic cases.
Why the study?
Three-dimensional printing enables the creation of physical models from digital images to assist in surgical planning and decision making for complex cardiac tumors.
Systematic Review
Blinded reviewers during data extraction (blinded to authors and journal titles)
Yes
May aid planning for complex cardiac tumors; hypothesis-generating and requires prospective validation before practice change.
The application of three-dimensional (3D) printing enables the creation of material objects from digital images by depositing layers of plastic material into 3D structures and can be used for training, education, and surgical planning. We report two patients with large complex cardiac tumors where 3D technology was utilized to analyze the tumor size, location, and extension more precisely, allowing better preoperative planning and decision making.

Jabbari et al. (2016) conducted a systematic review in Benign or malignant pancreatic diseases requiring pancreatic surgery. Three-dimensional (3D) technologies (3D-CT reconstruction, 3D printing, augmented reality [AR], and virtual reality [VR]) vs. Conventional 2-dimensional (2D) cross-sectional imaging or absence of 3D modeling was evaluated on Applications and clinical/educational outcomes across preoperative planning, intraoperative navigation, and surgical training (descriptive synthesis; no single quantitative primary endpoint pooled due to heterogeneity). Three-dimensional technologies improved preoperative anatomical visualization in 32 of 40 planning studies (>90% arterial accuracy) and altered surgical decisions in 15%-35% of pancreatic cases.
