水充盈低张法在胃肿瘤性病变CT应用诊断中的价值研究

Value research into water-filling hypotonia method in CT application diagnosis of gastric tumor lesions

目的探讨水充盈低张法在胃肿瘤性病变CT应用诊断中的价值。方法选择经过纤维胃镜检查或者钡餐检查发现的胃肿瘤性病变患者50例,采用水充盈低张法进行胃部CT增强扫描和平扫,对患者肿瘤大小、位置、特征、形态及其周围结构关系等进行仔细观察。结果通过水充盈低张法能清楚显示肿瘤,有效充盈和扩张胃部,本研究50例胃肿瘤性病变患者中具体包括胃癌患者22例,胃间质瘤患者5例,平滑肌瘤患者6例,恶性淋巴瘤患者5例,胃平滑肌肉瘤患者6例,息肉样腺瘤或者胃腺瘤患者6例。结论采用水充盈低张法进行胃部CT增强扫描和平扫,能对是否存在肿瘤病变进行有效判断,同时还能对肿瘤性质进行判断,对恶性肿瘤是否存在远处转移以及周围浸润等现象进行观察。

Objective To investigate the value of water-filling hypotonia method in CT application diagnosis of gastric tumor lesions. Methods 50 sufferers with gastric tumor lesions found by fibergastroscopy or barium meal examination were selected to accept CT-enhanced scan and horizontal scan in the gastric area by means of water-filling hypotonia method,so as to closely observe the tumor size,location,characteristics,form and its peripheral structure relationship.Results Water-filling hypotonia method could clearly show the tumor,effectively fill and expand the stomach.Among the 50 sufferers with gastric tumor lesions,there were 22 cases of gastric cancer,5 cases of gastric stromal tumor,6 cases of leiomyoma,5 cases of malignant lymphoma,6 cases of gastric leiomyosarcoma,and 6 cases of polypid adenoma or gastric adenoma. Conclusion CT-enhanced scan and horizontal scan in the gastric area by means of water-filling hypotonia method can effectively judge the existence of tumor lesions,as well as the tumor nature,which can also observe the possibility of distant metastasis and peripheral invasion of malignant tumor.
