    Abstract:
    BACKGROUND: How the oncologic outcomes after robotic distal pancreatectomy (RDP) compare to those after laparoscopic distal pancreatectomy (LDP) remains unknown. METHODS: Using the National Cancer Database (NCDB), we analyzed all patients undergoing LDP or RDP for resectable pancreatic adenocarcinoma over a 4-year period (2010-2013). RESULTS: Of the 704 eligible patients, 605 (86%) underwent LDP and 99 (14%) underwent RDP. The median follow-up for patients was 25 months. There were no differences in the two groups with respect to sociodemographic, clinicopathologic, or treatment characteristics. On comparing LDP versus RDP, there was no difference in the margin-positive rate (15% vs 16%; P = 0.84); lymph nodes examined (12 vs 11; P = 0.67); overall survival (hazard ratio [HR], 1.1, 95% confidence intervals [CI], 0.7 to 1.7; 28 vs 25 months; P = 0.71); hospital stay (6 vs 5 days; P = 0.14); time to chemotherapy (50 vs 52 days; P = 0.65); 30-day readmission (9.4% vs 9.1%; P = 0.92); and mortality (1% vs 0%; P = 0.28). Patients undergoing LDP had a significantly higher conversion rate to open or minimally invasive pancreatic cancer resections compared with RDP (27% vs 10%; P < 0.001). CONCLUSION: The early national experience with RDP demonstrates similar oncologic outcomes to LDP, with a significantly lower conversion rate.
