- W3029593438 abstract "ObjectiveTo 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.MethodsFrom 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.ResultsThe 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).ConclusionsThe 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.Key words: Pancreatic neoplasms; Mesenteric artery, superior; Neoplasm metastasis; Prognosis" @default.
