目的：通过Ｘ线病理对照分析，对浸润型胃癌的早期Ｘ线征象及诊断问题进行探讨。材料与方法：手术切除的狭窄前期浸润型胃癌１０例，术后标本行病理学对照检查，比较不同Ｘ线征象的病理学意义。结果：全部病灶均出现局限性的胃壁伸展受限和Ⅱｃ样凹陷灶，病变主要位于大弯侧。大皱襞型癌浸润主要位于粘膜下层及其深层，小区破坏型的粘膜层内癌浸润则更为明显。结论：浸润型胃癌诊治的关键是在胃腔狭窄出现之前做出正确诊断；局限性的大弯侧胃壁伸展受限和Ⅱｃ样凹陷灶是浸润型胃癌最常见的早期Ｘ线征象；粘膜皱襞的不同Ｘ线表现标志着癌组织在胃壁内浸润程度的不同；足量的气体和钡剂使胃壁充分伸展和对胃内凹陷灶的精细检查是避免漏、误诊的关键。
Objective: To explore the early X-ray signs and diagnosis of invasive gastric cancer by X-ray pathology analysis. Materials and Methods: Surgical resection of prestenotic invasive gastric cancer was performed in 10 cases. Postoperative specimens were examined by pathological examination to compare the pathological significance of different X-ray signs. RESULTS: All the lesions showed limited limitations of gastric wall extension and IIc-like depressions. The lesions were mainly located on the side of the greater curvature. The infiltrates of the large plica type carcinoma are mainly located in the submucosa and its deep layers, and the infiltration of cancer in the submucosal layer of the community is even more pronounced. Conclusion: The key to the diagnosis and treatment of invasive gastric cancer is to make a correct diagnosis before the occurrence of gastric cavity stenosis; limitations of the large curvature of gastric wall extension and IIc-like depression are the most common early X-ray signs of invasive gastric cancer; mucosal folds Different X-ray findings indicate the degree of invasion of the cancerous tissue in the stomach wall; sufficient gas and tincture to make the stomach wall fully stretched and the fine examination of the gastric depression is the key to avoid leakage and misdiagnosis.
