Background: To evaluate a risk-adjusted comparison of clinically relevant postoperative pancreatic fistula POPF (CR-POPF) following laparoscopic pancreatoduodenectomy (LPD) vs open pancreatoduodenectomy (OPD) using the fistula risk score (FRS). Methods: We retrospectively analyzed 579 patients who underwent LPD (n = 274) or OPD (n = 305) between 2012 and 2019 at two tertiary hospitals. Using the FRS, the risk was stratified into four categories; negligible, low, intermediate and high risk. Results: The median FRS was significantly higher in the LPD than in the OPD group (5.4 ± 1.2 vs 3.9 ± 1.8, P <.001). The overall incidence of CR-POPF in the LPD vs OPD groups were 16.4% vs 17.7% (P =.187). When POPF risks were stratified by FRS, CR-POPF following LPD vs OPD in patients with low risk (0% vs 6.3%, P =.294), intermediate risk (16.1% vs 22.9%, P =.053) and high risk (33.3% vs 27.3%, P =.577) were not significantly different. Conclusion: Despite a higher risk score in the LPD group, the CR-POPF was similar following both procedures in the unadjusted and FRS-risk-adjusted comparisons. The CR-POPF was more significantly affected by patient risk factors such as the soft pancreas and small pancreatic duct.
