Background: The qualitative evaluation for laparoscopic training of medical students was performed using Rubric evaluation, and weak points in conjunction with the lack of anatomical knowledge were derived. To conquer these weak points, virtual reality (VR) + augmented reality (AR) training for understanding of regional anatomy was investigated.
Materials and Methods: One hundred and six students in 5th grade of Tokushima Univ. participated basic laparoscopic task training (gummy band ligation, beads transfer, delivery of beads, gauze excision) with training box and sham laparoscopic cholecystectomy with virtual simulator. Rubric evaluation, as qualitative evaluation, which includes the evaluation standards for each maneuver were performed before and after basic task training and sham operation. The group which self-evaluation was higher in a Rubric evaluation was investigated.
The 3D image of vessels and bile duct obtained from MDCT of real patient was projected in reality space with Microsoft HoloLens. Training of AR image using HoloLens was performed for understanding of regional anatomy. After training with HoloLens, rubric evaluation was performed in sham operation again.
Results: Rubric evaluation in basic task training showed no difference between self-evaluation and evaluation by tutor before and after practice. In sham laparoscopic cholecystectomy, several students showed higher score than tutor, especially in part of extension of operation field by elevation of the Gall bladder, exposure of triangle of Calot, and exposure of cystic duct.
After AR training, all students showed high score in questions related regional anatomy during operation. Especially, rubric evaluation of students who showed high self-evaluation in sham operation showed same score with tutor.
Conclusions: As Rubric evaluation showed weak points of detailed parts of maneuver, and VR+AR was useful for understanding details of regional anatomy for laparoscopic training.
