超声内镜对胰腺癌可切除性评估的价值分析

Value of endoscopic ultrasonography in assessment of resectability of pancreatic carcinoma

目的探讨内镜超声检查术(EUS)对胰腺癌的可切除性评估的价值。方法收集在术前均经EUS、BUS以及CT检查,后经手术治疗,并最终为病理组织学证实为胰腺癌的病例。对EUS在术前对胰腺癌的可切除性评估进行回顾分析,以手术结果为金标准进行对比,并与BUS以及CT诊断结果进行比较。结果21例接受手术治疗,其中6例术前EUS认为可切除,实际术中切除5例,EUS评估胰腺癌可切除性的准确度为83.3%;15例术前EUS评估为不可切除,实际手术无法切除14例,EUS评估不可切除准确度为93.3%。提示EUS术前评估结果与手术结果一致性较好。EUS诊断胰腺癌准确率为95.2%,CT为90.5%,B超为71.4%。结论应用EUS评估胰腺癌的可切除性是一种有效的方法。

Objective To study the value of endoscopic ultrasonography （EUS） in assessment of the resectability of pancreatic carcinoma. Methods Twenty-one cases with pancreatic carcinoma,who underwent pancreatectomy and all were confirmed by histopathology,received EUS,BUS and CT examinations. The resectahility of pancreatic carcinoma was assessed by EUS,BUS and CT findings in comparison with surgical finding as the gold standard. Results Six and 14 cases out of 21 cases were considered as resectable and inresectable by EUS before surgery respectively. Compared with surgical finding there was 1 false negative and 1 false positive case with a sensitivity of 83.3% and a specificity of 93.3%. The accuracy rates of EUS,CT and B-type sonography in assessment of resectability of pancreatic carcinoma were 95. 2%, 90. 5% and 71.4%, respectively. Conclusion Endoscopic ultrasonography is an effective method to assess the resectability of pancreatic carcinoma before operation.
