Deliberate practice enhances quality of laparoscopic surgical performance in a randomized controlled trial: from arrested development to expert performance
Résumé
BACKGROUND: This study investigated whether deliberate practice leads to an increase in surgical quality in virtual reality (VR) laparoscopic cholecystectomies (LC). Previous research has suggested that sustained DP is effective in surgical training. METHODS: Fourteen residents were randomized into deliberate practice (n=7) or control training (n=7). Both groups performed ten sessions of two VR LCs. Each session, the DP group was assigned 30min of DP activities in between LCs while the control group viewed educational videos or read journal articles. Performance was assessed on speed and dexterity; quality was rated with global (GRS) and procedure-specific (PSRS) rating scales. All participants then performed five porcine LCs. RESULTS: Both groups improved over 20 VR LCs in time, dexterity, and global rating scales (all p
