目的：评价Ｘ线双对比造影诊断Ⅱｃ型早期胃癌的价值。材料和方法：对经Ｘ线双对比造影、胃镜检查并经手术病理证实的１０３例Ⅱｃ型早期胃癌进行Ｘ线双对比造影、病理对照研究。结果：绝大部分（９６．１％）病变位于胃中远部。低分化腺癌发病率与管状腺癌相近，两者浸润深度无显著性差异。癌性病变的主要诊断依据是：病灶区浅凹陷面、周围粘膜纠集和局限性腔壁线伸展不良。结论：熟练掌握造影技术和熟悉病变的基本征象对于发现和诊断Ⅱｃ型早期胃癌是十分重要的。
Objective: To evaluate the value of double contrast angiography in the diagnosis of type Ⅱc early gastric cancer. Materials and Methods: X-ray double contrast angiography and pathological control study of 103 cases of type Ⅱc early gastric cancer confirmed by double contrast angiography, gastroscopy and pathological examination. Results: The vast majority of lesions (96.1%) were located in the distal stomach. The incidence of poorly differentiated adenocarcinoma is similar to that of tubular adenocarcinoma, with no significant difference between the two. The main diagnosis of cancerous lesions are based on: shallow focus of the lesion area, the surrounding mucosal collection and limitations of parietal stretch poor. Conclusion: Proficiency in imaging techniques and familiar with the basic signs of lesions for the detection and diagnosis of early gastric cancer Ⅱ c is very important.
