【摘要】：目的研究不同病理分期、病理分型胃癌组织的介电性差异。方法 20例患者的腹腔镜胃癌术后标本,每例标本选取6个胃癌组织和6个正常胃组织位点,利用开端同轴线测定其介电性,检测后取下检测位点全层组织进行HE染色,分析对比不同病理分期、Lauren分型胃癌的介电性差异。结果不同分期胃癌组织与正常胃组织介电性均有显著差异(P0.05),并且随着分期进展,介电性参数逐渐升高(P0.05)。肠型胃癌介电性要明显高于弥漫型胃癌(P0.05)。结论开端同轴线能够较好地检测出早期胃癌与正常胃组织介电性的差异以及不同病理分型胃癌组织介电性的差异,有望为胃镜提供具有诊断意义的病理信息。
[Abstract]:Objective to study the difference of dielectric properties of gastric cancer with different pathological stages and types. Methods after laparoscopic gastric cancer operation, 6 gastric cancer tissues and 6 normal gastric tissue sites were selected from 20 patients. The dielectric properties of the samples were determined by the starting coaxial line, and the whole tissue of the detection site was stained with HE. To analyze and compare the difference of dielectric properties of gastric cancer with different pathological stages and Lauren classification. Results there were significant differences in dielectric properties between gastric cancer and normal gastric tissues in different stages, and the dielectric parameters increased gradually with the progression of stage. The dielectric properties of intestinal gastric carcinoma were significantly higher than that of diffuse gastric carcinoma (P 0.05). Conclusion the beginning coaxial line can detect the difference between early gastric cancer and normal gastric tissue and the difference between different pathological types of gastric cancer, which is expected to provide pathological information with diagnostic significance for gastroscopy.
