Objective
For patients with pancreatic and peri-ampullary adenocarcinoma, it has been hypothesized that extended lymphadenectomy may result in higher R0 resection rates and improved survival. As such, the objective of this systematic review was to compare the oncologic outcomes after pancreaticoduodenectomy (PD) with standard lymphadenectomy (SLA) versus PD with extended lymphadenectomy (ELA).
Methods
A Cochrane systematic review was conducted to identify all randomized controlled trials comparing PD with SLA versus PD with ELA for participants with periampullary or pancreatic cancer. The following electronic databases were reviewed: the Cochrane Central Register of Controlled Trials; MEDLINE; PubMed and EMBASE. The methodological quality of the included studies was assessed using the Cochrane risk of bias criteria and the quality of evidence for important outcomes using GRADE. Extended lymphadenectomy included the interaortocaval space, left side of the celiac trunk, and superior mesenteric artery.
Results
Seven randomized controlled trials were included with 843 patients (421 ELA and 422 SLA). No difference in overall survival (1- and 3-years after surgery) was seen between groups. Mortality and morbidity rates (including pancreatic fistula, delayed gastric emptying, and postoperative bleeding) were similar between the two groups. Operative time was significantly longer following extended resection (Mean Difference 50.1 min; 95% CI 19.2 to 81.1 min; P = 0.001). Total amount of blood loss during surgery was significantly increased following extended resection (Mean Difference 137 ml; 95% CI 12 to 263 ml; P = 0.03), as well as transfusion requirements (Mean Difference 0.15 units; 95% CI 0.13 to 0.17 units; P < 0.00001). More lymph nodes were retrieved during ELA (Mean Difference 11 nodes; 95% CI 7 to 15 nodes; P < 0.00001). Incidence of positive resection margins was not different between groups.
Conclusion
There is no indication for extended lymphadenectomy in pancreatic head resection as a routine procedure.
