Abstract

Background: Robotic distal pancreatectomy exhibits short-term benefits over laparoscopic distal pancreatectomy. The use of minimal invasive techniques to carry out distal pancreatosplenectomy (DPS) for pancreatic ductal adenocarcinoma (PDAC) remains controversial and has not gained popular acceptance. A comparative study was designed to analyze the short- and mid-term outcomes of robotic DPS (RDPS) versus laparoscopic DPS (LDPS) on patients with PDAC.

Methods: The baseline characteristics, perioperative outcomes and survival data among patients who underwent RDPS (n = 35) versus LDPS (n = 35) for PDAC between December 2011 and December 2015 were compared after a 1:1 propensity score matching.

Results: There were no significant differences in the operative time, blood loss, blood transfusion rate, and morbidity and pancreatic fistula rates between the RDPS and LDPS groups. RDPS significantly reduced the rate of conversion to laparotomy (5.7% vs. 22.9% when compared with LDPS, p = 0.04). There were no significant differences in R0 resection rates, number of harvested lymph nodes, positive to harvested lymph node ratios, and disease-free survival and overall survival rates between the two groups. A Cox proportional hazards analysis showed N1 stage to be significantly associated with worse survival and suggested that chemotherapy might prolong overall survival in these PDAC patients.

Conclusions: This single-center study demonstrated that RDPS was safe and efficacious in treatment of PDAC. When compared with LDPS, RDPS was associated with a reduced rate of conversion to open surgery. There were no significantly differences in oncological outcomes and mid-term survival rates between the groups of patients who underwent RDPS or LDPS.
