Assessing the perioperative complications and outcomes of robotic pancreaticoduodenectomy using the National Cancer Database: is it ready for prime time?

Robotic pancreaticoduodenectomy has generated significant interest in recent years. Our study aimed to evaluate the difference in surgical, oncological, and survival outcomes after pancreaticoduodenectomy (PD) by either a robotic (RPD) or open approach (OPD). Using the National Cancer Database, we identified patients from 2010 and 2017 diagnosed with pancreatic adenocarcinoma and underwent pancreaticoduodenectomy by either robotic PD or open approach. Patients who underwent robotic PD during 2010 were compared to patients receiving the same procedure in 2017. In addition, a secondary analysis was performed to assess outcomes of robotic PD to open PD for the 2017 patient cohorts. Our primary outcomes included 30-day and 90-day mortality, length of stay, as well as 30-day readmission. Secondary outcome measures were surgical margins, lymph node yield, and adjuvant chemotherapy initiation within 12 weeks of surgery. When we compared the 2017 data to 2010 data, we found that robotic pancreaticoduodenectomy had lower 30- and 90-day mortality rates in 2017 compared to 2010. Additionally, we found that the lymph node yield in robotic PD increased during the study period. When we compared robotic PD to open PD for 2017, we found no statistically significant differences in readmission rates (10.1% vs. 9.7%: p-0.4), lymph node yield, or negative margin between the groups. Outcomes of robotic PD have improved over the years. In 2017, outcomes of robotic PD were similar to open PD.
