目的 探讨内镜超声（EUS）检查对胰腺癌的诊断价值。方法 对116例胰腺癌患者行EUS检查,其中16例经管内超声（IDUS）检查并与体表B超（B超）、CT、磁共振成像（MRI）、内镜逆行胰胆管造影（ERCP）检查结果进行比较。结果EUS（包括IDUS）诊断胰腺癌的敏感性与准确性均明显高于B超,与CT、MRI及ERCP相当。EUS诊断准确率为98.2％（114/116）,IDUS为100％（16/16）;CT为85.3％（99/116）;MRI为87.0％（54/62）;ERCP为80.6％（79/98）;B超为73.2％（85/116）。结论 EUS对胰腺癌有较大的诊断价值。
Objective To investigate the diagnostic value of endoscopic ultrasonography (EUS) in pancreatic cancer. Methods One hundred and sixteen patients with pancreatic cancer underwent EUS. Among them, 16 cases were examined by IDUS and combined with B ultrasound, CT, MRI, endoscopic retrograde cholangiopancreatography (ERCP) Check the results for comparison. Results The sensitivity and accuracy of EUS (including IDUS) in the diagnosis of pancreatic cancer were significantly higher than those of B ultrasound, which were similar to those of CT, MRI and ERCP. The diagnostic accuracy of EUS was 98.2% (114/116), IDUS was 100% (16/16), CT was 85.3% (99/116), MRI was 87.0% (54/62) and ERCP was 80.6% (79 / 98); B ultrasound was 73.2% (85/116). Conclusion EUS has great diagnostic value for pancreatic cancer.
