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.

Residents' decision-making accuracy
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.
Time frame: Immediately after completing the educational intervention
Cognitive knowledge retention
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.
Time frame: Baseline and immediately after completing the educational intervention
Residents' scores in recognizing intrahepatic structures and liver segments
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 frame: Immediately after completing the educational intervention
Time needed to devise a surgical plan using the DI or VR platform
Assessed by total time needed to make decision for 10 patient cases in minutes
Time frame: Immediately after completing the educational intervention
