Brief summary
Investigators hypothesize that a virtual reality (VR) environment enhances general surgery residents' performance compared to Desktop Interface (DI)-based visualization of 3D models in decision making for patients with liver tumors. To determine this, a proficiency-based stepwise training curriculum for preoperative planning has been developed using both modalities. The overall objective of the curriculum is that by the end of the training program, residents would be able to formulate a treatment plan for patients with liver tumors.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Residents' decision-making accuracy | Immediately after completing the educational intervention | Residents' decision-making accuracy when reviewing patient data and 3D liver models using DI or VR, measured by comparing their performance to experts' opinions. The measurement tool will be a questionnaire consisting of ten questions, rate of correct answers will be recorded (e.g. 8/10 correct answers) and higher scores mean a better outcome. Minimum score=0; Maximum score=10. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Cognitive knowledge retention | Baseline and immediately after completing the educational intervention | Retention of knowledge assessed by validated multiple choice questions. Questionnaire consisted of 15 questions will be used, rate of correct answers will be recorded (e.g. 8/15 correct answers), and higher scores mean a better outcome. Minimum score=0; Maximum score=15. |
| Residents' scores in recognizing intrahepatic structures and liver segments | Immediately after completing the educational intervention | Assessed by recognizing intrahepatic structures and 8 liver segments. Questionnaire consisted of 22 questions will be used, rate of correct answers will be recorded (e.g. 8/22 correct answers), and higher scores mean a better outcome. Minimum score=0; Maximum score=22. |
| Time needed to devise a surgical plan using the DI or VR platform | Immediately after completing the educational intervention | Assessed by total time needed to make decision for 10 patient cases in minutes |
