Perceptions of Porta Celiac Vascular Model

A multi-item survey was prepared to assess fellow's perception of residency training. The survey was utilized by our group, understanding of patient vascular anatomy, awareness of the changes based on variations, independent decision-making, differential diagnosis, plan on key surgical steps, and preparation for unexpected bleeding. The answers to the questions asked for each case were analyzed to include senior (3 years and over) - junior (1-2 years) residents.Assistants spend 45 minutes in the survey. Data are entered into SPSS 24.0 for statistical analysis. Wilcoxon Signed Ranks Test was used to determine any significant differences in the measurements between the original CT images, 3D rendered images, the 3D model and CT images of the 3D model. Statistical significance was defined as a p value of less than 0.05. Junior assistants stated that they perceived 2D image statistically better than 3D models compared to the senior assistants (Kruskal-Wallis Test).
