Abstract

To analyze the initial learning curve (LC) for robot-assisted pancreaticoduodenectomy (RAPD) and compare RAPD during the initial LC with open pancreaticoduodenectomy (OPD) in terms of outcome. This study is a retrospective review of patients who consecutively underwent RAPD and OPD between October 2015 and January 2020 in our hospital. 41 consecutive RAPD cases and 53 consecutive open cases were enrolled for review. Compared with OPD, RAPD required a significantly longer operative time (401.1 ± 127.5 vs. 230.8 ± 44.5 min, P < 0.001) and higher cost (194621 ± 78342 vs. 121874 ± 39973 CNY, P < 0.001). Moreover, compared with the OPD group, the RAPD group revealed a significantly smaller mean number of lymph nodes harvested in malignant cases (15.6 ± 5.9 vs 18.9 ± 7.3, P = 0.025). No statistically significant differences were observed between the two groups in terms of incidence of Clavien–Dindo grade III–V morbidities and 90-day mortality and readmission (P>0.05). In the CUSUM graph, one peak point was observed at the 8th case, after which the operation time began to decrease. LC for RAPD may be less than 30 cases, and RAPD is safe and feasible during the initial LC.

Highlights

  • To analyze the initial learning curve (LC) for robot-assisted pancreaticoduodenectomy (RAPD) and compare RAPD during the initial LC with open pancreaticoduodenectomy (OPD) in terms of outcome

  • Laparoscopic pancreaticoduodenectomy (LPD) presents intrinsic disadvantages compared with conventional laparotomy, including instrument motion, two-dimensional imaging, poor surgeon ergonomics, and a long LC

  • 41 cases and 53 cases were scheduled for RAPD and OPD, respectively, between January 2016 and January 2020

Summary

Introduction

To analyze the initial learning curve (LC) for robot-assisted pancreaticoduodenectomy (RAPD) and compare RAPD during the initial LC with open pancreaticoduodenectomy (OPD) in terms of outcome. Compared with OPD, RAPD required a significantly longer operative time (401.1 ± 127.5 vs 230.8 ± 44.5 min, P < 0.001) and higher cost (194621 ± 78342 vs 121874 ± 39973 CNY, P < 0.001). Compared with the OPD group, the RAPD group revealed a significantly smaller mean number of lymph nodes harvested in malignant cases (15.6 ± 5.9 vs 18.9 ± 7.3, P = 0.025). Laparoscopic pancreaticoduodenectomy (LPD) was first reported in 1994 by Gagner[2]; today, this procedure could be performed as safely as open pancreaticoduodenectomy (OPD) by skilled surgeons[3,4]. LPD presents intrinsic disadvantages compared with conventional laparotomy, including instrument motion, two-dimensional imaging, poor surgeon ergonomics, and a long LC. This article addresses the LC of a single surgical team in our hospital
