本文对60例经手术及/或胃镜病理证实的中后期胃癌,进行了超声显像与X线双对比造影的对照研究。结果表明:X线对中后期胃癌检出的阳性率(95％)显著高于超声(81.7％)(P<0.05),诊断正确率(93.3％)同样显著高于超声(71.6％)(P<0.05)。对转移病例的检出,超声(88％)却显著高于X线(12％)(P<0.05),超声对胃癌浸润程度的评定亦远较X线为优。但超声显像不应作为诊断胃癌的首选方法。
In this article, 60 cases of gastric cancer in the middle and late stages confirmed by pathology of surgery and/or gastroscopy were studied by contrast-enhanced ultrasound and X-ray double contrast. The results showed that the positive rate (95%) detected by X-ray in late-stage gastric cancer was significantly higher than that in ultrasound (81.7%) (P<0.05), and the diagnostic accuracy rate (93.3%) was also significantly higher than that of ultrasound (71.6%). <0.05). Ultrasound (88%) was significantly higher than that of X-ray (12%) in the detection of metastatic cases (P < 0.05). Ultrasound was also superior to X-ray in assessing the extent of gastric cancer infiltration. However, ultrasound imaging should not be used as the preferred method for the diagnosis of gastric cancer.
