Footnote: Time for anastomosis in TRDG group was calculated from the surgeon operating the robot to the abdominal closure, preoperative disinfection, towel time, and anesthesia is not included. Time for anastomosis in RADG group was calculated from the beginning of transecting duodenum to the end of gastrointestinal anastomosis and detaching the robotic system
