To explore the safety, short-term efficacy and advantages of robotic surgery system in pancreaticoduodenectomy.

The clinical data of 88 patients with pancreatic diseases who underwent pancreaticoduodenectomy with da Vinci Robotics operation system and laparoscopic surgery system in the first affiliated Hospital of South China University from Mar. 2015 to Mar. 2022 were analyzed retrospectively.

All patients were operated successfully. In the robot group (38 cases), the median operation time was 5.00 h(4.15 h, 5.73 h), the median intraoperative blood loss was 100.00 mL (50.00 mL, 150.00 mL), 1 case had abdominal infection. Among the postoperative accelerated rehabilitation indexes, the median time of first feeding, defecation, drainage and hospital stay were 3.00 d(2.75 d, 4.00 d), 5.00 d(4.00 d, 6.00 d), 12.00 d(8.00 d, 14.25 d) and 13.50 d(9.75 d, 16.00 d) respectively. In the laparoscopy group (n=50), the median operation time was 8.00h and the median intraoperative blood loss was 200.00 mL (150.00 mL, 200.00 mL), 7 cases were converted to laparotomy, 10 cases had abdominal infection. Among the postoperative accelerated rehabilitation indexes, the median time of first feeding, defecation, drainage and hospital stay were 5.00 d(4.00 d, 6.00 d), 6.00 d(5.00 d, 6.00 d), 20.00 d(16.00 d, 21.75 d) and 19.50 d(17.00 d, 29.25 d) days respectively. There was significant difference in the above-mentioned indexes between the two groups (P<0.05).

Under the background of enhanced recovery after surgery, RPD has more obvious advantages than LPD in operative safety, complications and rapid recovery.
