目的探讨超声内镜(EUS)诊断胰腺癌的价值。方法12例经体表B超、CT、MR I检查疑诊胰腺癌患者,予EUS检查,诊断结果与体表B超、CT、MR I、组织病理学进行对比。结果12例病人均行EUS检查,其中8例病人进行了手术治疗,EUS对胰腺癌平均特异性、敏感性在T及N期均明显高于影像学检查,M期影像学检查的敏感性、特异性高于EUS。结论EUS是一种新型的特殊内镜对胰腺癌有很高的诊断价值,值得在临床推广。
Objective To investigate the value of endoscopic ultrasonography (EUS) in the diagnosis of pancreatic cancer. Methods 12 cases of suspected pancreatic cancer were examined by body surface ultrasonography, CT, and MR I. EUS was performed. The results were compared with B ultrasound, CT, MR I, and histopathology. Results EUS was performed in 12 patients and 8 of them underwent surgical treatment. The average specificity and sensitivity of EUS to pancreatic cancer in T and N phases were significantly higher than those in imaging. The sensitivity of M phase imaging examination was Specificity is higher than EUS. Conclusion EUS is a new type of special endoscopy with high diagnostic value for pancreatic cancer and is worthy of clinical promotion.
