摘要
目的 研究CT泪滴状肠系膜上静脉 (SMV)征能否可靠判断胰头癌的不可切除性。方法 回顾性分析 98例经手术病理证实的胰头癌 ,对照分析CT表现及手术病理 ,评价泪滴状SMV征反映胰头癌不可切除性的敏感性、准确性和特异性。结果 在增强CT上 ,泪滴状SMV征结合其他CT表现可明显提高胰头癌不可切除的敏感性 (从 6 1%到 89% )和准确性 (从 70 %到 91% ) ,但对可切除的特异性无显著影响 (从 10 0 %到 96 % )。结论 泪滴状SMV征是胰头癌不可切除性的可靠表现 。
Objective To study whether a teardrop shaped superior mesenteric vein (SMV) is a reliable CT sign of unresectable adenocarcinoma in the head of pancreas. Methods Enhanced CT images of ninety eight patients with pancreatic carcinomas proved by pathology were retrospectively reviewed by two radiologists who were unfamiliar with the final diagnosis. Surgical and pathological outcomes were used as the reference standard to determine the sensitivity, accuracy and specificity of teardrop shaped SMV. Results Added to conventional signs, teardrop SMV significantly increased CT's sensitivity (from 61% to 89%) and accuracy (from 70% to 91%) without significantly changing its specificity (from 100% to 96%) for evaluating resectability of carcinoma in pancratic head. Conclusion The teardrop SMV is a reliable CT sign for predicting unresectability of adenocarcinoma of the pancreatic head and can significantly contribute to preoperative planning. [
