Clinical degree of the superior mesenteric vein involvement with the surgery in the pancreas uncinate process carcinoma / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSIONS</b>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.</p>
