摘　　要：目的:探讨胃窗超声造影与双重超声造影用于胃癌分期判断及胃间叶源性肿瘤检出的临床价值。方法:选择42例胃癌患者及31例胃间叶源性肿瘤患者作为研究对象,均进行胃窗超声造影和双重超声造影,比较不同造影方法的诊断价值。结果:胃窗超声造影对T1期、T2期、T3期及T4期胃癌诊断准确率为55.5%、66.7%、66.7%、66.7%。超声双重造影对T1期、T2期、T3期及T4期胃癌诊断准确率分别为77.8%、94.4%、88.9%和83.3%。胃窗超声造影和双重超声造影对胃间叶源性肿瘤的检出率分别为93.5%和74.2%。胃窗超声造影对胃癌病理T分期诊断准确率低于双重超声造影(P<0.05),双重超声造影的敏感性、特异性均高于胃窗超声造影(P<0.05)。结论:双重超声造影对胃癌病理分期的诊断准确率和对胃间质叶源性肿瘤的检出率均较高,可在临床推广应用。Objective:To explore the clinical value of oral ultrasonic contrast agent ultrasound and double contrast enhanced ultrasonography in the staging of gastric cancer and the detection of gastric cancer.Methods:42 patients with gastric cancer and 31 patients with gastric mesenchymal tumor were selected as the research objects.Both oral ultrasonic contrast agent ultrasound and double contrast enhanced ultrasonography were used to compare the diagnostic value of different contrast-enhanced methods.Results:The accuracy of the staging of gastric cancer of T1 T2,T3,T4,diagnosed with oral ultrasonic contrast agent ultrasound,was 55.5%,66.7%,66.7%and 66.7%,respectively.The accuracy of the staging of gastric cancer of T1 T2,T3,T4,diagnosed with double contrast enhanced ultrasonography were 77.8%,94.4%,88.9%,and 83.3%,respectively.The detection rate of gastrointestinal stromal tumors with oral ultrasonic contrast agent ultrasound and double contrast enhanced ultrasonography were 93.5%and 74.2%,respectively.The diagnostic accuracy of oral ultrasonic contrast agent ultrasound for pathological T staging of gastric cancer was lower than that of double contrast enhanced ultrasonography(P<0.05).The sensitivity and specificity of double contrast enhanced ultrasonography were higher than those of oral ultrasonic contrast agent ultrasound(P<0.05).Conclusion:The diagnostic accuracy of double contrast enhanced ultrasonography in the pathological staging of gastric cancer and the detection rate of gastric stromal tumors are high,which can be widely used in clinical practice.
