目的：通过对胃恶性溃疡旁粘膜病变的Ｘ线－病理对照研究，旨在说明胃溃疡癌变存在的事实。材料与方法：对１８例胃恶性溃疡的１２２处胃切面，采用放射状象限取材对照法观察溃疡旁粘膜病变。结果：胃溃疡癌变溃疡病灶与周围交界面主要Ｘ线表现为小段弧形隆起，边缘较规则，杵状皱襞、纤细皱襞可达溃疡龛影的边缘或小段弧形隆起的边缘；溃疡旁Ｘ线表现以迂曲粗大皱襞及纤细条纹状皱襞为主，病理镜下改变是以慢性浅表性胃炎为主。溃疡型胃癌溃疡病灶与周围交界面主要Ｘ线表现为小带状无皱襞区，近溃疡侧的纤细不规则皱襞与远侧的杵状皱襞相接；溃疡旁Ｘ线表现是粘膜皱襞影像多较模糊，尤以模糊条纹状皱襞及模糊网格状伴有“靶征”居多，病理镜下改变是以慢性萎缩性胃炎、肠上皮化生及胃粘膜上皮异型增生等癌前病变为主。结论：胃溃疡癌变与溃疡型胃癌是两种病，胃溃疡癌变的存在亦是客观事实。同时鉴于癌组织有“潜掘式”浸润的特点，因此在Ｘ线判断病变的范围时应引起注意
OBJECTIVE: Through the X-ray pathological control study of mucosal lesions of gastric ulcer, the purpose of this study is to show the existence of gastric ulcer carcinogenesis. MATERIALS AND METHODS: 122 gastric sections of 18 patients with gastric malignant ulcer were treated with radial quadrant radiography to observe the mucosal lesion of ulcer. Results: The main X-ray of gastric ulcer lesion and surrounding interface showed a small arc-shaped bulge, the edge of the rule is more regular, clubbing folds, slender folds up to the edge of the ulcer niche shadow or edge of a small arc; ulcer next to the X-ray The performance of tortuous thick folds and slender striped folds mainly pathological microscopic changes of chronic superficial gastritis based. Ulceration gastric ulcer lesion and the surrounding interface of the main X-ray showed a small strip of non-wrinkled area, near the ulcer slender irregular folds and distal clubbed folds; next to the ulcer X ray performance is more mucosal folds Blurred, especially in the fuzzy striated folds and fuzzy grid with the “target sign” mostly pathological microscopic changes in chronic atrophic gastritis, intestinal metaplasia and gastric epithelial dysplasia and other precancerous lesions based. Conclusion: Gastric ulcer carcinogenesis and ulcerative gastric cancer are two kinds of diseases, the existence of gastric ulcer carcinogenesis is also an objective fact. At the same time, given the “submerged” infiltration of cancerous tissue, attention should be paid to determine the extent of the lesion in the X-ray
