目的：分析双重超声造影在胃癌术前分期的诊断意义。方法选择166例胃癌患者为纳入研究，术前对其行双重超声造影检查，分别用胃窗超声造影与双重超声造影结果进行术前分期，精确分期以术后病理检查结果为准。结果双重超声造影T分期诊断符合率（82.2%）高于胃窗超声造影术前T分期（60.1%），差异有统计学意义（χ2=25.499，P＜0.05）。双重超声造影T1、T2、T3、T4诊断符合率分别为88.9%，82.8%，86.0%，88.7%，其中T2、T3和T4分期双重造影诊断符合率优于胃窗超声造影，差异有统计学意义（χ2=6.340、4.150、11.257，P=0.011、0.042、0.001）。结论超声双重造影对胃癌术前分期有一定的临床价值。

Objective To investigate the diagnostic value of double contrast-enh anced ultrasonography (DUCS) in the preoperative T staging of gastric cancer. Methods A total of 166 patients with gastric cancer were enrolled in the study. All the cases have been preoperatively evaluated with the DUCS before the surgery. The diagnostic accuracy of oral ultrasonic contrast agent or DUCS for TNM staging of gastric cancer was determined by subsequent postoperative histopathologic findings. Results The overall accuracy of total T stage of DUCS was statistically higher than the oral ultrasonic contrast agent( 82.2%vs 60.1%, χ2=25.499, P < 0.05), while the accuracy of T1, T2, T3 and T4 stage was 88.9%, 82.8%, 86.0% and 88.7%, respectively. Compared with the oral ultrasonic contrast agent, the accuracy of T2, T3 and T4 stage of DUCS were obviously higher ( χ2= 6.340, 4.150, 11.257; P = 0.011, 0.042, 0.001, respectively). Conclusion The DUCS might have some clinical value on evaluating the preoperative T stage of gastric cancer.
