目的 探讨早期胃癌X线表现与浸润深度的关系。方法 总结了经胃肠气钡双重造影及手术病理证实的 19例早期胃癌X线表现 ,并与其浸润深度作了对照分析。结果 经手术证实的 19例中 ,黏膜内癌 9例 ,黏膜下癌 10例。黏膜内癌主要X线表现为胃壁舒张度减低 ,轮廓线模糊 ,胃小区增大 ,出现大小不等的颗粒样阴影 ,胃小沟模糊紊乱 ,似石榴籽样 ;黏膜下癌主要X线表现为胃壁僵直 ,局部密度增高 ,有小的充盈缺损 ,不规则形龛影 ,局部黏膜皱襞粗大、僵直、中断 ,胃小区小沟破坏。早期胃癌有功能性的改变 :异常收缩 ,滞留液增多。结论 胃肠气钡双重造影对早期胃癌的浸润深度有一定的诊断价值
Objective To investigate the relationship between the X-ray findings and the depth of invasion in early gastric cancer. Methods The X-ray findings of 19 cases of early gastric cancer confirmed by double-contrast gastrointestinal barium double angiography and surgical pathology were summarized and compared with the depth of invasion. Results 19 cases confirmed by surgery, 9 cases of intramucosal carcinoma, submucosal carcinoma in 10 cases. The main X-ray findings of intramucosal carcinoma were the decrease of gastric wall dilation, blurred contour lines, enlargement of gastric area, particle-like shadows with different sizes, blurring of gastric minor groove and pomegranate-like appearance. The main X-ray findings of submucosal carcinoma were Stomach wall stiffness, increased local density, a small filling defect, irregular shaped niche, local mucosal folds thick, stiff, interrupted, small cell damage in the stomach area. Early gastric cancer have functional changes: abnormal contraction, retention fluid increased. Conclusion Gastrointestinal double contrast barium has a certain diagnostic value for the depth of invasion of early gastric cancer
