    Abstract:
    BACKGROUND: The frequency of minimally invasive distal pancreatectomy is gradually exceeding that of the open approach. Our study aims to compare short-term outcomes of robotic (RDP) and laparoscopic (LDP) distal pancreatectomies for pancreatic ductal adenocarcinoma (PDAC) using a national database. METHODS: The National Cancer Database was utilized to identify patients with PDAC who underwent distal pancreatectomy from 2010-2020. Short-term technical and oncologic outcomes such as margin status and nodal harvest were included. Propensity-score matching (PSM) was performed comparing LDP and RDP cohorts. Multivariate logistic-regression models were then used to assess the impact of institutional volume on the MIDP surgical and technical oncologic outcomes. RESULTS: 1537 patients underwent MIDP with curative intent. Most cases were laparoscopic (74.4%, n = 1144), with a gradual increase in robotic utilization, from 8.7% in 2010 to 32.0% of MIDP cases ten years later. For PSM, 698 LDP patients were matched with 349 RDP. The odds of conversion to an open case were 58% less in RDP (12.6%) compared to LDP (25.5%) with no statistically significant difference in technical oncologic results. There was no difference in length of stay (OR = 1.0[0.7-1.4]), 30-day mortality (OR = 0.5[0.2-2.0]) or 90-day mortality (OR = 1.1[0.5-2.4]) between RDP and LDP, although there was a higher 30-day readmission rate with RDP (OR = 1.71[1.1-2.7]). There were statistically significant differences in technical oncologic outcomes (nodal harvest, margin status, initiation of adjuvant therapy) based on MIDP volume quartiles. CONCLUSION: Laparoscopic and robotic distal pancreatectomy have similar peri- and post-operative surgical and oncologic outcomes, with a higher rate of conversion to open in the laparoscopic cohort.
