Abstract

The utilization of minimally invasive distal pancreatectomy (MIDP) is increasing, yet debate remains regarding its oncologic safety in the setting of pancreatic adenocarcinoma (PDAC). Herein we present our institutional experience with robotic (RDP), laparoscopic (LDP), and open distal pancreatectomy (ODP) in the setting of PDAC.

Retrospective review of a prospectively collected single institutional database of patients undergoing consecutive ODP, LDP, and RDP for left-sided PDAC between January 2008 and December 2019 at the University of Pittsburgh Medical Center (UPMC) was done. Perioperative and postoperative outcomes were compared using non-parametric testing and Fischer exact or chi-squared testing. Kaplan–Meier survival curves for disease-free survival and overall survival were compared by Log-Rank sum test. Backward Cox-proportional hazard regression analysis was used to determine if the operative approach was an independent predictor of recurrence and overall survival.

Over 12 years, 146 consecutive distal pancreatectomies for PDAC were performed, of which 28.1% ODP, 60.3% RDP, and 11.6% LDP. There were no statistical differences in patients’ baseline characteristics, including gender, comorbidities, prior abdominal surgeries, and AJCC8th stage (p > 0.05). Postoperatively, there was no difference in the frequency of major complications (p = 0.414), CR-POPF (p = 0.563), or DGE (p = 0.179). The median overall survival was 28.4 months for ODP, 34.6 months for RDP, and 32.5 months for LDP (Log Rank p = 0.914). On multivariate Cox proportional hazard analysis, the surgical approach was not associated with overall survival. This comparative analysis suggests a non-inferiority of RDP platforms, compared to LDP and classic ODP. The merits of MIS pancreatic surgery in the setting of PDAC should be evaluated in future prospective studies with care to analyze RDP outcomes separately from LDP.
