INTRODUCTION: The purpose of the study is to compare perioperative and survival outcomes in elderly patients undergoing laparoscopic pancreaticoduodenectomy (LPD) to those undergoing open pancreaticoduodenectomy (OPD). METHODS: Patients aged ≥ 75 years with pancreatic adenocarcinoma undergoing LPD or OPD were identified from the NCDB (2010-2013). Baseline characteristics and perioperative outcomes were compared using a χ 2 and Student's t test. The Kaplan-Meier method was used to generate survival curves, and differences were tested using a log-rank test. A multivariate cox proportional hazard model was applied to estimate the hazard ratio (HR) of LPD on overall survival (OS). RESULTS: We identified 1768 patients aged ≥ 75 years who underwent LPD (n = 248, 14.0%) or OPD (n = 1520, 86.0%). The majority of patients in the LPD group had their surgery at facilities performing less than 5 LPDs per year (n = 165, 66.5%). 90-day mortality was significantly lower in the LPD compared to the OPD (7.2 vs. 12.2%, p = 0.049). The laparoscopic conversion rate was 30% (n = 74) and was associated with higher readmission rates (13.5 vs. 8.1%), 30-day mortality (8.0 vs. 3.8%), and 90-day mortality (10.4 vs. 6.0%), but these did not reach statistical significance. Median OS was significantly longer in the LPD group (19.8 vs. 15.6 months, p = 0.022). After adjusting for patient and tumor-related characteristics, there was a trend towards improved survival in the LPD group (HR 0.85, 95% CI 0.69-1.03). CONCLUSION: The vast majority of the NCDB participating facilities perform less than 5 LPD cases per year, which was associated with an increased risk of perioperative mortality. Overall 90-day mortality was significantly lower in the LPD group and there was a trend towards improved OS in the LPD group compared to the OPD group after adjusting for patient and tumor-related characteristics. Studies with increased sample size and longer follow-up are needed before definitive conclusions can be made.
