胃癌的数字胃肠造影与CT诊断对照分析

目的研究数字胃肠造影和CT在胃癌诊断中的价值。方法用数字胃肠和CT分别对42例胃癌进行检查，并对二种检查结果进行对比分析。结果42例胃癌中，数字胃肠造影的特征为胃粘膜破坏40例，胃腔狭窄12例，恶性溃疡10例，充盈缺损12例，蠕动异常36例。CT检查特征为胃壁增厚30例，胃腔内肿块36例，胃腔狭窄36例，周围淋巴结及远处脏器转移19例，幽门梗阻4例。结论数字胃肠造影能清楚显示胃腔内变化，照片清楚细致。CT对胃腔外的肿块范围、淋巴结和远处器官转移的诊断和手术适应证的评估具有重要价值。

A comparative study of digital GI and CT in diagnosis of gastric carcinoma

Objective To evaluate the digital GI and CT in the diagnosis of gastric carcinoma. Methods In total 42 patients with gastric carcinoma recieved digital GI and CT examination. The digital GI and CT findings were analyzed comparatively. Results 42 cases of patients with gastric carcinoma were examined with digital GI and CT. Digital GI demonstrated mucosal erosion in 40 cases, narrowed gastric lumen in 12, malignant ulceration in 10, filling defect in 12 and abnormal peristalsis in 36. CT revealed gastric wall thickening in 30 cases, intra-gastric masses in 36, narrowed gastric lumen in 36, regional lymphadenopathy and/or distant metastases in 19 and pyloristenosis in 4. Conclusion The lesions in stomach could be demonstrated on digital GI, the imaging is clear and precise. CT is valuable for assessing the extra-gastric involvement, lymphadenopathy and distant metastases, which is an important pre-operative examination.
