摘　　要：目的提高临床胰腺癌的确诊率。方法回顾性分析北京协和医院1996年至2004年问256例资料完整胰腺癌患者的临床表现及各种影像学检查结果,包括B超、CT、ERCP、超声内镜检查(EUS)、血管造影(DSA)、MRI等。结果体重减轻是胰腺癌患者最多见的症状,发生率达79%;除体重减轻外,胰头癌最突出的症状是黄疸,而上腹痛在体尾癌的发生率达86%。B超、CT、ERCP、EUS、DSA、MRI对胰腺癌诊断的准确率分别为83%、89%、90%、91%、82%、79%。结论患者出现不能解释的上腹痛、黄疸、体重减轻等症状时应怀疑有胰腺癌,并进行B超、CT检查,对高度怀疑而前两者检查阴性者应考虑进一步行EUS、ERCP或MRI等检查。To evaluate the value of clinical data and various methods of diagnostic imaging in the patients with pancreatic cancer. Methods Two hundreds and fifty-six patients with pancreatic cancer admitted into Peking Union Medical College Hospital between 1996 and 2004 were included. The clinical symptom and the accuracy of various imaging methods （B-US, CT, ERCP, EUS, DSA and MRI） in assessing pancreatic carcinoma were analyzed. Results Weight lost was the most common symptom in 79% of patients with pancreatic carcinoma. Jaundice was mostly seen in patients with pancreatic head carcinoma. Upper abdominal pain was in 86% of patients with carcinoma in pancreatic body and tail. The diagnostic accuracies of B-US, CT, ERCP, EUS, DSA and MRI were 83% , 89% , 90%, 91% , 82% and 79% respectively. Conclusion B-US and CT scanning should be undergone in patients with abdominal pain, jaundice and weight lost who were suspected to have pancreatic carcinoma. Further imaging techniques such as EUS, ERCP and MRI should be advised in patients highly suspected to have pancreatic carcinoma, in spite of the results of B-US and CT were negative.
