Surgical and Oncological Outcomes of Laparoscopic Versus Open Pancreaticoduodenectomy in Patients With Pancreatic Duct Adenocarcinoma.

It is not clear which of the 2 principal treatments for patients with pancreatic duct adenocarcinoma (PDAC), laparoscopic pancreaticoduodenectomy (LPD) and open pancreaticoduodenectomy (OPD), has greater safety and efficacy. We performed the present meta-analysis to assess the efficacy of both treatments for PDAC patients undergoing LPD. Multiple electronic databases were systematically searched to identify studies (up to October 2018) comparing LPD with OPD for PDAC. Short- and long-term oncological outcomes were evaluated. Six studies were qualified for inclusion criteria in this meta-analysis with a total of 9144 PDAC participants. Regarding safety, there were fewer overall postoperative complications associated with LPD (P = 0.005), but the results were similar in terms of pancreatic fistula and mortality. Laparoscopic pancreaticoduodenectomy was associated with a better trend of performance both in R0 resection (relative risk, 1.03; 95% confidence interval [CI], 1.00-1.07; P = 0.07) and preserved lymph nodes (median, 2.14; 95% CI, -0.21 to 4.49; P = 0.07). Long-term overall survival was comparable between LPD and OPD (hazard ratio, 1.03; 95% CI, 0.95-1.13; P = 0.49). In conclusion, LPD was found to be a suitable alternative to OPD in selected PDAC patients with respect to both surgical and oncological outcomes.
