An interventional study of Clinical decision making based on visualizing liver 3D models in Virtual Reality (VR) environment or via a Desktop Interface (DI) in Hepatobiliary Neoplasm, sponsored by University Hospital, Ghent. Completed at 2 sites in 2 countries. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2021-07-13.

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.
University Hospital, Ghent is the lead sponsor of 665 studies on the registry; 156 are open to participants now.

Exclusion Criteria:
Group A received first five patient cases and 3D models via DI and another five cases in the VR environment
Behavioral: Clinical decision making based on visualizing liver 3D models in Virtual Reality (VR) environment or via a Desktop Interface (DI)
Group B received first five patient cases and 3D models via VR and another five cases in the DI.
Behavioral: Clinical decision making based on visualizing liver 3D models in Virtual Reality (VR) environment or via a Desktop Interface (DI)
Visualizing 3D models of livers for preoperative surgical planning via two different environment: DI and VR in sequential order
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
