【摘要】 目的研究食管动态双对比造影(DDCR)在早期食管癌(EEC)诊断中的应用价值。方法采用数字胃肠机对疑诊为EEC患者进行常规双对比造影(CDCR)和/或DDCR检查,随机抽取经内镜或手术病理证实且2种造影资料均具有的40例EEC,采用双盲法分析,评价其诊断的可靠性。结果病变主要表现为局部黏膜粗细不均、扭曲以及不规则的小龛影和充盈缺损,病变区食管壁柔软度及舒张度减低,甚至消失。DDCR对EEC局部功能的显示明显优于CDCR,两者有统计学意义的差异(2χ=4.50,Р<0.05)。结论DDCR在EEC的诊断中具有较高价值,是一种较理想的检查方法。更多还原

【Abstract】 Objective To study the role of esophageal dynamic double contrast radiography(DDCR) in diagnosing early esophageal carcinoma(EEC).Methods The patients with clinical suspected EEC underwent conventional double contrast radiography(CDCR) and DDCR using digital fluoroscopic imaging unit.The radiographic materials including CDCR and DDCR in 40 cases of EEC proved by endoscopy or pathologic histology were analyzed by a blind study,and the reliability of CDCR and DDCR was evaluated.Results The major findings of EEC included the mucosal irregularity and tortuous,small niches and filling defect,the soft and expansive extent of esophageal wall reduced or disappeared.In showing the esophageal function,DDCR was significantly superior to CDCR(χ~2=4.50,Р<0.05).Conclusion DDCR is of important value and is a satisfactory method in diagnosing EEC.更多还原
