双重超声造影在胃癌诊断中的应用价值

Application of Double Contrast-enhanced Ultrasonography in the Diagnosis of Gastric Cancer

目的探讨双重超声造影在胃癌诊断中的应用价值.方法回顾性分析2014年10月至2015年7月昆明医科大学第三附属医院收治的26例经病理证实为胃癌的患者的双重超声造影检查资料,与术后病理比较.结果双重超声造影在胃癌定位、定性、T分期中诊断符合率分别为:100%(26/26)、100%(26/26)、88.5%(23/26).与普通超声检查比较,DCUS对胃癌的术前定性诊断准确率高于普通超声检查,差异有统计学意义(P<0.05);对胃癌的术前T分期诊断明显高于普通超声检查,差异无统计学意义(P>0.05).结论双重超声造影在胃癌诊断中具有重要的应用价值.

Objective To investigate the clinical value of double contrast-enhanced uhrasonography （DCUS） for the diagnosis of gastric cancer. Methods A retrospective analysis was performed to review the DCUS data of 26 patients which were diagnosed as gastric cancer by pathology in the third affiliated hospital of Kunming Medical University from October 2014 to July 2015. The analysis results were co .mpared with postoperative pathology to get accuracy rates. Results The located accuracy, qualitative accuracy and accuracy at T phase of DUCS was 100% （26/26）, 100% （26/26） and 88.5% （23/26）, respectively. Compared with color doppler flow imaging （CDFI） , the qualitative accuracy of DUCS was much higher （P 〈 0.05） . The accuracy of DUCS at T phase was higher than that of CDFI with no statistical significance （P 〉 0.05） Conclusion DUCS has an important application value in the diaznosis of zastric cancer.
