title: [Clinical degree of the superior mesenteric vein involvement with the surgery in the pancreas uncinate process carcinoma].
abstract: OBJECTIVE
  To create the clinical degree of the superior mesenteric vein (SMV) involvement in pancreas uncinate process carcinoma (PUPC) and its clinical significance to be discussed.
  
  
  METHODS
  According to the contiguous relationship between the SMV and the PUPC, the clinical degree of SMV involvement in PUPC are as followings four grades, 1 grade, the grade of clear boundary. 2 grade, the grade of fuzzy boundary. 3 grade, the grade of dissolved boundary. 4 grade, the grade of SMV infringed. The coherence between the type under the CT scan (Tx) and the type under the inoperative judgement (Sx) were analyzed with Kappa-test.
  
  
  RESULTS
  There is a significant difference between the grade of SMV involvement and the surgery. The resection rate is 100% in 1st grade, 97.4% in 2nd grade, 65.8% in 3rd grade and 21.7% in 4th grade. There is coherent in the degree judgement between the CT scan and the inoperative inspection (U = 15.96, P < 0.01).
  
  
  CONCLUSIONS
  There is clinical significance to establish the degree of SMV involvement in PUPC. It is helpful for clinician to accurately know its anatomic characteristic and decide more reasonable surgical strategy.
