本文介绍食道钡剂—胶体溶液双重造影法应用于检查早期食道癌。本法的主要优点:(一)检查技术操作简便,胶液量易控制,病员乐于接受,安全无害;(二)能使正常段扩张,粘膜皱襞展平,钡膜涂布较薄,暂无蠕动和小气泡影响。因此,立体感比较强,能避免重叠掩盖;(三)能清楚显示细微病变如粘膜增粗,毛糙及迂曲中断,小龛影,小充盈缺损和局部功能紊乱等。这些特点表明它对早期食道瘤的诊断价值优于钡—气双重造影,更优于普通钡餐法。
This article describes the esophageal liniment-colloidal solution double contrast method applied to the examination of early esophageal cancer. The main advantages of this method are as follows: (1) The inspection technique is easy to operate, the glue volume is easy to control, the patient is happy to accept it, safe and harmless; (2) It can make the normal segment expand, the mucous membrane folds flatten, and the thin film coating is temporary. No creep and small bubble effects. Therefore, the three-dimensional feeling is relatively strong, which can avoid overlap and cover; (c) can clearly show subtle lesions such as thickening of the mucous membranes, coarsening and disruption of disruption, small defects, small filling defects, and local dysfunction. These characteristics indicate that its diagnostic value for early esophageal neoplasms is better than that of phlegm-breath contrast imaging, and it is better than ordinary barium meal method.
