Abstract
BACKGROUND: There is no general consensus on the feasibility and safety of robotic pancreatoduodenectomy (RPD) and whether it increases surgical risks. The purpose of this study was to assess the safety, feasibility, and rationality of RPD by comparing perioperative data among open pancreatoduodenectomy (OPD), laparoscopic pancreatoduodenectomy (LPD), and RPD performed in our center in recent years. METHODS: Clinical data of patients had undergone RPD (n = 32), LPD (n = 21), and OPD (n = 86) in The First Affiliated Hospital of Guangxi Medical University between January 2016 and June 2020 were retrospectively collected and analyzed. RESULTS: RPD required more time for operation (537.2 min vs. 441.5 min, p < 0.001) than OPD did, but less time to remove abdominal drainage tube (12.5 d vs. 17.3 d, p = 0.001). The differences between the RPD group and LPD group were interesting, as the two groups had similar operation time (537.2 min vs. 592.9 min, p = 1.000) and blood loss (482.8 ml vs. 559.5 ml, p > 0.05), but the RPD group had a higher activity of daily living score on postoperative day 3 (35.8 vs. 25.7, p = 0.0017) and a lower rate of conversion to OPD (6.5% vs. 38.1%, p = 0.011). Regarding complications, such as the postoperative pancreatic fistula, abdominal hemorrhage, intra-abdominal infection, bile leakage, reoperation, and perioperative mortality, there were no significant differences among the three groups. CONCLUSIONS: Not only is RPD feasible and reliable, it also offers significant advantages in that it improves postoperative recovery of skills needed for everyday life, has a low conversion rate to open surgery, and does not increase surgical risks.
