| Abstract: | BACKGROUND: The superior mesenteric artery (SMA) first approach was proposed recently as a new modification of the standard pancreaticoduodenectomy. Increasing evidence showed that a periadventiceal dissection of the SMA with early transection of the inflow during pancreaticoduodenec-tomy associates better early perioperative results, and setup the scene for long-term oncological benefits. The objectives of the current study are to compare the operative results and long-term oncological outcomes of SMA first approach pan-creaticoduodenectomy (SMA-PD) with standard pancreatico-duodenectomy (S-PD).DATA SOURCES: Electronic search of the PubMed/MEDLINE, EMBASE, Web of Science and Cochrane Library was performed until July 2015. We considered randomized controlled trials (RCTs) and non-randomized comparative studies (NRCSs) comparing SMA-PD with S-PD to be eligible if they included patients with periampullary cancers.RESULTS: A total of one RCT and thirteen NRCSs met the in-clusion criteria, involving 640 patients with SMA-PD and 514 patients with S-PD. The SMA-PD was associated with less in-traoperative bleeding, less blood transfusions and higher rate of associated venous resections. The pancreatic fistula and delayed gastric emptying had a significantly lower rate in the SMA-PD group. There were no differences between the two approaches regarding overall complications, major complica-tion rates and in-hospital mortality. There was no difference regarding R0 resection rate, and one-, two- or three-year over-all survival. The SMA-PD was associated with a lower local, hepatic and extrahepatic metastatic rate.CONCLUSIONS: The SMA-PD is associated with better perioperative outcomes, such as blood loss, transfusion re-quirements, pancreatic fistula, and delayed gastric emptying. Although the one-, two- or three-year overall survival rate is not superior, the SMA-PD has a lower local and metastatic re-currence rate. |
