Abstract
Background
Evidence of the advantages of robotic pancreaticoduodenectomy (RPD) over laparoscopic pancreaticoduodenectomy (LPD) is limited. Thus, this study aimed to compare the surgical outcomes of laparoscopic reconstruction L-recon) versus robotic reconstruction (R-recon) in patients with soft pancreas and small pancreatic duct.
Method
Among 429 patients treated with minimally invasive pancreaticoduodenectomy (MIPD) between October 2012 and June 2020 by three surgeons at three institutions, 201 patients with a soft pancreas and a small pancreatic duct (< 3 mm) were included in this study.
Results
Sixty pairs of patients who underwent L-recon and R-recon were selected after propensity score matching. The perioperative outcomes were comparable between the reconstruction approaches, with comparable clinically relevant postoperative pancreatic fistula (CR-POPF) rates (15.0% [L-recon] vs. 13.3% [R-recon]). The sub-analysis according to the type of MIPD procedure also showed comparable outcomes, but only a significant difference in postoperative hospital stay was identified. During the learning curve analysis using the cumulative summation by operation time (CUSUMOT), two surgeons who performed both L-recon and R-recon procedures reached their first peak in the CUSUMOT graph earlier for the R-recon group than for the L-recon group (i.e., 20th L-recon case and third R-recon case of surgeon A and 43rd L-recon case and seventh R-recon case of surgeon B). Surgeon C, who only performed R-recon, demonstrated the first peak in the 22nd case. The multivariate regression analysis for risk factors of CR-POPF showed that the MIPD procedure type, as well as other factors, did not have any significant effect.
Conclusion
Postoperative pancreatic fistula rates and the overall perioperative outcomes of L-recon and R-recon were comparable in patients with soft-textured pancreas and small pancreatic duct treated by experienced surgeons.
