目的：探讨对比增强超声造影对胃下部癌区域淋巴结转移的预测价值。方法采用六氟化硫微气泡造影剂和连续实时成像对比脉冲序列技术，对250例经胃镜活检确诊的胃下部癌患者术前行超声造影及螺旋CT检查，诊断区域淋巴结转移情况，并与术后病理检查结果对比。结果对比增强超声造影预测胃下部癌区域淋巴结转移的准确率、敏感度、特异度、Youden指数分别为71.2%、70.3%、88.5%、0.588，螺旋CT预测结果分别为71.4%、66.4%、89.9%、0.563，两者预测区域淋巴结转移准确率的差异均无统计学意义（均P＞0.05）。两者联合应用的预测准确率为82.5%。对比增强超声造影预测第3、8a、8p组淋巴结转移准确率明显高于螺旋CT；预测第1、11p组淋巴结转移准确率明显低于螺旋CT，差异均有统计学意义（P＜0.05或0.01）。结论对比增强超声造影预测胃下部癌区域淋巴结转移具有一定的价值；对比增强超声造影联合螺旋CT检查可提高预测胃下部癌区域淋巴结转移的准确率。
目的：探討對比增彊超聲造影對胃下部癌區域淋巴結轉移的預測價值。方法採用六氟化硫微氣泡造影劑和連續實時成像對比脈遲序列技術，對250例經胃鏡活檢確診的胃下部癌患者術前行超聲造影及螺鏇CT檢查，診斷區域淋巴結轉移情況，併與術後病理檢查結果對比。結果對比增彊超聲造影預測胃下部癌區域淋巴結轉移的準確率、敏感度、特異度、Youden指數分彆為71.2%、70.3%、88.5%、0.588，螺鏇CT預測結果分彆為71.4%、66.4%、89.9%、0.563，兩者預測區域淋巴結轉移準確率的差異均無統計學意義（均P＞0.05）。兩者聯閤應用的預測準確率為82.5%。對比增彊超聲造影預測第3、8a、8p組淋巴結轉移準確率明顯高于螺鏇CT；預測第1、11p組淋巴結轉移準確率明顯低于螺鏇CT，差異均有統計學意義（P＜0.05或0.01）。結論對比增彊超聲造影預測胃下部癌區域淋巴結轉移具有一定的價值；對比增彊超聲造影聯閤螺鏇CT檢查可提高預測胃下部癌區域淋巴結轉移的準確率。

Objective To evaluate contrast- enhanced ultrasonography (CEUS) in diagnosis of regional lymph node metastasis in the lower third gastric cancer. Methods A sulfur hexafluonde- fil ed microbubble ultrasound contrast agent and a continuous real- time imaging technique of contrast pulse sequencing were used.Two hundred and fifty patients with lower third gastric cancer confirmed by biopsies, who received preoperative CEUS and MSCT examinations, were enrol ed in this study. The results of lymph node metastasis detected by CEUS were compared with postoperative pathological findings. Results The accuracy, sensitivity, specificity and Youden Index of CEUS and MSCT in assessment of lymph node metastasis were 71.2%, 70.3%, 88.5% and 0.588;71.4%, 66.4%, 89.9%and 0.563, respectively. There was no significant difference in the accuracy of assessment of lymph node metastasis(χ2=2.86, P>0.05). The accuracy of CEUS combined with MSCT was 82.5%. The accura-cies of CEUS in assessment of the No.3, 8a, 8p groups were higher than those of MSCT, while the accuracies of the No.1, 11p groups were lower than those of MSCT (P<0.05); there were no significant differences in other groups (P>0.05). Conclusion DCUS combined with MSCT can improve the diagnostic accuracy of regional lymph node metastasis in the lower third of gastric cancer.
