    ¡¾Abstract¡¿AIM: To detect the value of contrast ultrasonography in the diagnosis of advanced gastric cancer. METHODS: Sixtyª²three patients with suspected advanced gastric cancer were examined by contrast ultrasonography after taking in gastric contrast medium that mixed by 10 mL ultrasonographic contrast medium and 400-600 mL pure water. The 63 patients also had gastroscopy and biopsy and results of contrast ultrasonography were compared with those of gastroscopy and biopsy. RESULTS: Fiftyª²nine patients were diagnosed to have gastric cancer by contrast ultrasonography, among whom, 23 were lumpish shaped, 8 localized ulcer like, 3 infiltrative ulcer like and 25 with infiltration. Gastroscopyª²directed biopsy findings showed that 1 case had been misdiagnosed positively and another case had been misdiagnosed negatively. The total diagnostic coincidence, sensitivity and specificity, was 96.8%, 98.3% and 75.0%, respectively. CONCLUSION: Contrast ultrasonography can accurately reflect the morphologic characteristics of advanced gastric cancer and can also provide more reliable information for the diagnosis and classification of gastric cancer. ......
