目的 :探讨高频超声对胃癌的诊断价值 ,提高胃癌的检出率及诊断符合率。方法 :对 62例经手术、胃镜活检病理证实的胃癌声象图进行分析。结果 :胃癌声象图的直接征象是胃壁的异常增厚、隆起 ,呈低回声 ,结构失常 ,形态不规则。转移征象表现为胃周围淋巴结转移、腹水、肝转移、Krukenberg瘤。本组超声诊断部位与手术证实基本符合。结论 :采用高频超声不仅可以提高进展期胃癌的检出率和诊断符合率 ,也可发现早期胃癌。
Objective: To investigate the diagnostic value of high-frequency ultrasound in gastric cancer, improve the detection rate of gastric cancer and the diagnostic compliance rate. Methods : Sixty-two cases of gastric carcinomas confirmed by surgery and gastroscope biopsy were analyzed. Results: The direct signs of gastric cancer acoustic image were abnormal thickening and bulging of gastric wall, hypoechoic, abnormal structure and irregular shape. The metastases manifested as lymph node metastasis, ascites, hepatic metastases, Krukenberg tumor. The ultrasound diagnostic site in this group was basically in accordance with the surgical confirmation. Conclusion: High-frequency ultrasound can not only improve the detection rate and diagnostic coincidence rate of advanced gastric cancer, but also detect early gastric cancer.
