Brief summary
The goal of this trial is to compare the evaluation of 3D liver models visualised as holograms with HoloLens 2 and on digital PDF files in HPB surgical trainees. The main questions it aims to answer are: * Do the holographic models allow a superior accuracy in terms of anatomical evaluation and surgical planning? * Is there any difference in terms of time consumed and Task Load Index? Participants will analyse cases through both modalities and answer a questionnaire.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Diagnostic and planning accuracy | Immediately after completing the evaluation | Correctly identify anatomy and appropriate surgical planning Residents' decision-making accuracy when reviewing patient data and 3D liver models using Holograms or on PDF, measured by comparing their performance. The measurement tool will be a questionnaire consisting of 11 questions, rate of correct answers will be recorded (e.g. 8/10 correct answers) and higher scores mean a better outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Time consumed | Immediately after completing the evaluation | Analyse the time spent for the evaluation of the cases and complete the questionnaire Assessed by total time needed to make decision for 15 patient cases in minutes |
| NASA Task Load Index | Immediately after completing the evaluation | Analyse the NASA TLI score for each participant to evaluate the cases by conducting a subjective mental workload assessment rating performance across six dimensions to determine an overall workload rating: 1. Mental demand - how much thinking, deciding, or calculating was required to perform the task. 2. Physical demand - the amount and intensity of physical activity required to complete the task. 3. Temporal demand - the amount of time pressure involved in completing the task. 4. Effort - how hard does the participant have to work to maintain their level of performance? 5. Performance - the level of success in completing the task. 6. Frustration level - how insecure, discouraged, or secure or content the participant felt during the task. Each participant gives a rating for each subscale from 1 (low) to 20 (high) and the TLX will calculate the overall worklaod score between 0 and 100 |
