Background Reports on the safety of minimally invasive pancreaticoduodenectomy compared to open pancreaticoduodenectomy (OPD) have demonstrated mixed results. One study comparing robotic pancreaticoduodenectomy (RPD) vs OPD demonstrated decreased complications associated with RPD. Objectives To evaluate the morbidity of RPD vs OPD using a national data set. Methods This is a retrospective cohort study from 2014 to 2017. Factors associated with complications in patients undergoing pancreaticoduodenectomy were evaluated using multivariate logistic regression (MVA) and propensity score matching (PSM). Results Of 13 110 PDs performed over the study period, 12 612 (96.2%) were OPD and 498 (3.8%) were RPD. Patients who underwent RPD vs OPD were less likely to have any complications (46.8% vs 53.3%; P = .004), surgical complications (42.6% vs 48.6%; P = .008), wound complications (6.2% vs 9.1%; P = .029), clinically relevant postoperative pancreatic fistulas (11.9% vs 15.6%; P = .026), sepsis (6.2% vs 9.3%; P = .019), and pneumonia (1.6% vs 3.8%; P = .012). On MVA, OPD was associated with increased complications compared with RPD. On PSM analysis, OPD remained a significant predictor for any (OR, 1.29; 95% CI, 1.03‐1.61; P = .029) and surgical (OR, 1.26; 95% CI, 1.00‐1.58; P = .048) complications. Conclusions This is the largest multicenter study to evaluate the impact of RPD on morbidity and suggests RPD is associated with decreased morbidity.

Background: Pancreatic ductal adenocarcinoma (PDAC) is associated with increased venous thromboembolism (VTE). We sought to compare rates of bleeding complications and VTE in patients receiving extended postoperative thromboprophylaxis (EPT) to those who did not, and identify risk factors for VTE after pancreatectomy for PDAC.Methods: This is a retrospective review of pancreatectomies for PDAC. EPT was defined as 28 days of low molecular weight heparin. Multivariable analysis (MVA) was performed to identify independent risk factors of VTE.Results: Of 269 patients included, 142 (52.8%) received EPT. Of those who received EPT, 7 (4.9%) suffered bleeding complications, compared to 6 (4.7%) of those who did not (p = 0.938). There was no significant difference in VTE rate at 90 days (2.8% vs. 2.4%, p = 0.728) or at 1 year (6.3% vs. 7.9%, p = 0.624). On MVA, risk factors for VTE included worse performance status, lower preoperative hematocrit, R1/R2 resection, and minimally invasive (MIS) approach. Among those who received EPT, there was no difference in VTE rate between MIS and open approach.Conclusions: EPT was not associated with a difference in VTE risk or bleeding complications. MIS approach was associated with a higher risk of VTE; however, this was significantly lower among those who received EPT.
