Comparing laparoscopic and open pancreaticoduodenectomy in patients with pancreatic head cancer: oncologic outcomes and inflammatory scores

Background Both the technical and oncological safety of laparoscopic pancreaticoduodenectomy (LPD) remain controversial in treating pancreatic head cancer. We evaluated the oncologic benefit of LPD and compared the inflammatory score between LPD and open pancreaticoduodenectomy (OPD). Methods From January 2014 to March 2019, 61 patients with standard PD not combined with other organ resection were finally enrolled in this study. Among these patients, 27 underwent LPD and 34 underwent OPD (registered on 16 July 2019, and registration number is 2019‐1411‐001). Results The estimated blood loss (EBL) for the LPD group was less than that of the OPD group ( P  = 0.003). The operation time was similar, as was the incidence of complications such as postoperative fistula, delayed gastric emptying. Overall survival was not different between LPD and OPD (44.62 vs. 45.29 months, P  = 0.223). However, a significant improvement in disease‐free survival (DFS) was seen in the LPD group (34.19 vs. 23.27 months, P  = 0.027). No statistically significant differences were found in terms of the postoperative change in inflammatory scores and differentiated white blood cell counts. Conclusions LPD is not only safe and feasible in pancreatic head cancer patients but is associated with a reduced amount of EBL, favorable DFS.
