胰腺癌发展迅速,如早期不能作出诊断,则多无法治愈。但早期症状不明显,且位置深在,很难被一般的临床方法所发现,故早期诊断相当困难。近年来,由于现代化影像技术和新的生化技术的应用及细胞学检查,使胰腺癌的早期诊断有了很大进展,现综述如下。一、影像诊断方面(一)超声波检查B 超显像属非侵入性检查,操作简便、费用低廉、无离子辐射,是诊断胰腺癌的首选方法。因B 超检查可反复进行观察对比,诊断正确率较高。Pollock 等报道,其敏感性为94%,特异性为96%。Ihse
The rapid development of pancreatic cancer, if not diagnosed in the early stages, can not be cured. However, early symptoms are not obvious, and the location is deep, it is difficult to be found by general clinical methods, so early diagnosis is very difficult. In recent years, due to the application of modern imaging technology and new biochemical technologies and cytology, the early diagnosis of pancreatic cancer has made great progress, and is summarized as follows. I. Imaging Diagnosis (I) Ultrasound B Ultrasonography is a non-invasive examination. It is simple, inexpensive, and free from ionizing radiation. It is the preferred method for diagnosing pancreatic cancer. Because B-ultrasound can be repeatedly observed and compared, the diagnostic accuracy is high. Pollock et al. reported a sensitivity of 94% and a specificity of 96%. Ihse
