目的:应用阻抗式胃动力检测进行胃癌普查。方法:观察各期胃癌15 0例、胃溃疡80例、胃炎2 4 7例及健康成人10 0例的阻抗式胃动力特点,以发现胃癌患者的阻抗式胃动力特点及其特征性阻抗图轨迹。结果:试验性诊断胃癌2 8例,经电子胃镜检查及病检证实胃癌13例,准确率4 6 .4 %。结论:阻抗式胃动力检测可以发现胃癌胃动力和特异性表现,辅助诊断胃癌有一定的价值
OBJECTIVE: To screen gastric cancer by impedance gastric motility test. Methods: Observe the gastric motility characteristics of 15 cases of gastric cancer, 80 cases of gastric ulcer, 247 cases of gastritis and 100 cases of healthy adults. Observe the characteristic of impedance gastric motility and trace of characteristic impedance in gastric cancer patients . Results: Twenty-eight cases of gastric cancer were diagnosed by experiment. Thirteen cases of gastric cancer were confirmed by electron gastroscopy and pathological examination, with an accuracy rate of 46.4%. Conclusion: Impedance gastric motility test can find gastric motility and specificity of gastric cancer, and it is valuable to diagnose gastric cancer
