目的 评价经腹超声在进展期胃癌术前诊断和分型中的作用。方法 对 5 4例进展期胃癌患者进行了纤维胃镜和经腹超声检查 ,所有患者均经手术治疗并将上述检查结果与术后病理结果对照。结果 经腹超声判断进展期胃癌的分型与病理结果一致性较好 ,Kappa值为 0 .74 ,经腹超声分型准确率为 79.6 3%。经腹超声对胃周围肿大淋巴结总显示率为 6 4 .1 % ,转移淋巴结显示率为 79.2 %。结论 经腹超声对进展期胃癌术前的诊断和分型有较高的准确性 ,在临床上有一定实用价值
Objective To evaluate the role of transabdominal sonography in preoperative diagnosis and classification of advanced gastric cancer. Methods 54 cases of advanced gastric cancer patients underwent fiber endoscopy and abdominal ultrasonography, all patients were treated by surgery and the above test results and postoperative pathological results. Results The results of transabdominal ultrasonography showed that the classification of the advanced gastric cancer was consistent with the pathological results. The Kappa value was 0.74, and the accuracy of transabdominal sonography was 79.6 3%. Transabdominal ultrasound on the stomach around the enlarged lymph nodes showed a total rate of 64.1%, lymph node metastasis rate was 79.2%. Conclusion Transabdominal ultrasonography has a high accuracy in preoperative diagnosis and classification of advanced gastric cancer and has clinical value
