Evaluation of the advising doctor for operating of medical student by laparoscopic surgery simulator

Abstract

Laparoscopic surgery is less intraoperative hemorrhaging and pain than open surgery, reducing the patient’s burden. However, laparoscopic surgery requires time for practicing to acquire the procedure due to restrictions such as work through instruments or limited viewing. In this study, we elucidate the relationship of evaluation of simulator and evaluation of advising doctor, and verified the possibility of constructing educational system including education as guidance. In this experiment, the subjects were surgeons with 18 years of experience of laparoscopic surgery to qualify as an instructor. The content of the experiment was the 5-grade evaluation for the work by viewing the candidate movie. The 5-grade evaluation is “A”, “B”, “C”, “D”, “E”, and it is an evaluation that it is bad from “A” to “E”. We compared them with the evaluation items of the simulator and focused on the items of moving distance of forceps considered to be related to the medical student’s skill. It was found that the shorter the moving distance, the better the evaluation by the advising doctor depending on the moving distance of the forceps. However, in “D” as well, it was a value approximate to “B”. From this, it is considered that the reason why the forceps movement distance was short in the medical students of “D” evaluation is because they forceps are not operated (not moving). Therefore, it is thought that more accurate evaluation can be made by evaluating no only the evaluation of the simulator but also the evaluation judgment of the advising doctor, that is, the operation of the forceps.
