A new surgical instrument is supposed to allow surgeon to do surgery with better performance. However, the learning period before getting used to the new instruments is necessary. The surgeon's stress to overcome the learning effect and the surgical outcome was rarely assessed. The comparative analysis of surgical outcome, surgeon's stress, and utilization of instruments for gastrectomy will be performed in prospective cohort study
Before the surgery, all the eligible patients will be explained regarding the study and informed consent will be given. During the surgery, the surgeon will wear heart rate monitoring device to monitor hear rate variability of the surgeon. The surgical procedure will be recorded. After the surgery, morbidity following surgery will be monitored and recorded. At 1 month after surgery, additional morbidity will be recorded.
