俯卧左侧抬高位钡餐双对比数字图像对早期贲门癌的诊断价值

Double contrast digital imaging in prone position with left side up in the diagnosis of early cardia carcinoma of stomach

目的 :研究气钡双对比造影俯卧左侧抬高位数字图像对早期贲门癌的诊断价值。方法 :搜集 2 8例经手术病理证实的早期贲门癌 ,采用 5 0 0mA岛津IDR 70 0遥控透视数字胃肠机 ,对比剂用青岛Ⅲ型双对比用硫酸钡 ,实时采集贲门区多种部位图像 ,着重采集俯卧左侧抬高位胃底贲门区像。结果 :2 8例早期贲门癌在俯卧左侧抬高位像上均能清晰显示该区微小病变。结论 :俯卧左侧抬高位胃底贲门区数字化图像能清晰显示该部位的异常X线征象 ,对早期贲门癌的诊断有积极的价值 ,尤其是癌肿未侵及食管下段时 ,显示病变优于其它摄影部位。

Objective:To study double contrast examination using digital imaging of prone position with left side up in the diagnosis of early cardia carcinoma.Methods:Double contrast examination was performed in 28 patients with early cardia carcinoma proved pathologically.When the patients were in prone position with left side up,images of various region were gathered in real time and especially images of cardiac orifice.Results:The shape of cardiac tumour could be shown in all cases examined with prone position with left side up.Conclusion:Prone position with left side up can display the patterns in cardiac orifice.It is valuable in diagnosis of cardia carcinoma and superior to any other methods while lower esophagus is not involved.
