Figure 1. The operative time of laparoscopic and robotic gastrectomy decreased significantly after the learning curves.

Figure 1

(A) The operative time of laparoscopic gastrectomy decreased after the 41th case. The arrows show the case number of robotic gastrectomy (RG) performed at the corresponding time of laparoscopic gastrectomy. (B) The operative time and docking time of robotic gastrectomy decreased after the 25th case.
