Abstract:
Objective To examine whether the boundary patterns of the superior mesenteric artery (SMA) in the preoperative contrasted enhanced computer tomography (CE-CT) could predict poor postoperative prognosis.Methods From January 2010 to December 2015,104 patients of pancreatic head ductal adenocarcinoma received radical pancreaticoduodenectomy by a single group of surgeons.All patients underwent CE-CT before operation.The clinicopathological characteristics and the prognosis were comparatively analyzed among the patients with different SMA boundary patterns.Results The patients with obscure SMA boundary in CE-CT had a lower overall survival rate (P =0.012) and a higher liver metastasis rate (P < 0.01) compared to the patients with clear SMA boundary.38.2% of patients with obscure SMA boundary died within 6 months,69.1% of them died within 12 months while the mortality rate was 6% within 6 months and 29.2% within 12 months in patients with clear SMA boundary.Only 2.2% of patients with clear SMA boundary presented liver metastasis within 6 months,but that was 53% in patients with obscure SMA boundary.18.4% of patients developed liver metastasis within 12 months in patients with clear SMA boundary,whereas the rate was 82% in patients with obscure SMA boundary.Furthermore,the tissues around the SMA presented a higher CT value in any phase in patients with obscure SMA boundary than in patients with clear SMA boundary (P < 0.01).Conclusions The patterns of the SMA boundary in CE-CT is a potential prognostic factor in pancreatic head ductal adenocarcinoma after radical operation,and the obscure SMA boundary may be associated with early liver metastasis and high mortality.
